FreeSync Only For New AMD Chips
AMD has explained that its new FreeSync technology will only work in new silicon.
FreeSync is AMD’s initiative to enable variable-refresh display technology for smoother in-game animation and was supposed to give Nvidia’s G-Sync technology a good kicking.
G-Sync has already resulted in some top production gaming monitors like the Asus ROG Swift PG278Q.
However AMD said that the only the newest GPU silicon from AMD will support FreeSync displays. Specifically, the Hawaii GPU that drives the Radeon R9 290 and 290X will be compatible with FreeSync monitors, as will the Tonga GPU in the Radeon R9 285.
The Bonaire chip that powers the Radeon R7 260X and HD 7790 cards could support FreeSync, but that is not certain yet.
Now that would be OK if the current Radeon lineup is populated by a mix of newer and older GPU technology. What AMD is saying is that there are some brand-new graphics cards selling today that will not support FreeSync monitors when they arrive.
The list of products that won’t work with FreeSync includes anything based on the older revision of the GCN architecture used in chips like Tahiti and Pitcairn.
So if you have splashed out on the the Radeon R9 280, 280X, 270, and 270X hoping that it will be FreeSync-capable you will be out of luck. Nor will any older Radeons in the HD 7000 and 8000 series.
Nvidia’s G-Sync works with GeForce graphics cards based on the Kepler architecture, which include a broad swath of current and past products dating back to the GeForce GTX 600 series.
AMD’s Carrizo Goes Mobile Only
AMD’s upcoming Carrizo APU might not make it to the desktop market at all.
According to Italian tech site bitsandchips.it, citing industry sources, AMD plans to limit Carrizo to mobile parts. Furthermore the source claims Carrizo will not support DDR4 memory. We cannot confirm or deny the report at this time.
If the rumours turn out to be true, AMD will not have a new desktop platform next year. Bear in mind that Intel is doing the exact same thing by bringing 14nm silicon to mobile rather than desktop. AMD’s roadmap previously pointed to a desktop Carrizo launch in 2015.
AMD’s FM2+ socket and Kaveri derivatives would have to hold the line until 2016. The same goes for the AM3+ platform, which should also last until 2016.
Not much is known about Carrizo at the moment, hence we are not in a position to say much about the latest rumours. AMD’s first 20nm APU will be Nolan, but Carrizo will be the first 20nm big core. AMD confirmed a number of delays in a roadmap leaked last August.
The company recently confirmed its first 20nm products are coming next year. In all likelihood AMD will be selling 32nm, 28nm and 20nm parts next year.
ARM Launches Juno
ARM has announced two programs to assist Android’s ascent into the 64-bit architecture market.
The first of those is Linaro, a port of the Android Open Source Project to the 64-bit ARMv8-A architecture. ARM said the port was done on a development board codenamed “Juno”, which is the second initiative to help Android reach the 64-bit market.
The Juno hardware development platform includes a system on chip (SoC) powered by a quad-core ARM Cortex-A53 CPU and dual-core ARM Cortex-A57 CPU in an ARM big.little processing configuration.
Juno is said to be an “open, vendor neutral ARMv8 development platform” that will also feature an ARM Mali-T624 graphics processor.
Alongside the news of the 64-bit initiatives, ARM also announced that Actions Semiconductor of China signed a license agreement for the 64-bit ARM Cortex-A50 processor family.
“Actions provides SoC solutions for portable consumer electronics,” ARM said. “With this IP license, Actions will develop 64-bit SoC solutions targeting the tablet and over-the-counter (OTT) set top box markets.”
The announcements from ARM come at an appropriate time, as it was only last week that Google announced the latest version of its Android mobile operating system, Android L, which comes with support for 64-bit processors. ARM’s latest developments mean that Android developers are likely to take advantage of them in the push to take Android to the 64-bit market.
Despite speculation that it would launch as Android 5.0 Lollipop, Google outed its next software iteration on Wednesday last week as simply Android L, touting the oddly-named iteration as “the largest update to the operating system yet”.
Intel Links Up With Rockchip
Intel has joined forces with Chinese chip design firm Rockchip to develop next generation processors for the tablet market based on Intel Atom core technology and integrating 3G broadband communications.
Under the terms of the agreement, Intel and Fuzhou Rockchip Electronics (Rockchip) will work together on an Intel branded mobile system on chip (SoC) processor with the intention of enabling a range of entry-level Android tablets.
The chip is expected to ship in the first half of 2015, according to Intel, and will be based on a quad-core Atom processor design integrated with Intel’s 3G modem technology, which the firm gained through its acquisition of Infineon Technologies in 2010.
Rockchip, which is expected to contribute to the integrated graphics technology, will also help Intel bring the product to market faster than might otherwise be the case. The firm is a leading fabless semiconductor design company and already develops mobile SoCs, although its present designs are largely focused around the ARM architecture.
The agreement builds on announcements Intel made at an investor relations day last year, where chief executive Brian Krzanich disclosed the Intel Sofia family, of which the latest chip will form part, and conceded that the chipmaker needed to become more agile in order to gain traction in entry-level markets.
“The strategic agreement with Rockchip is an example of Intel’s commitment to take pragmatic and different approaches to grow our presence in the global mobile market by more quickly delivering a broader portfolio of Intel architecture and communications technology solutions,” Krzanich said.
With this announcement, the Intel Sofia family comprises three products, which are not shipping yet.
A dual-core 3G version is slated for the fourth quarter this year, the quad-core 3G version is due in the first half of 2015, and a version with 4G/LTE communication is also due in the first half of next year.
ARM To Focus On 64-bit SoC
ARM announced its first 64-bit cores a while ago and SoC makers have already rolled out several 64-bit designs. However, apart from Apple nobody has consumer oriented 64-bit ARM devices on the market just yet. They are slowly starting to show up and ARM says the transition to 64-bit parts is accelerating. However, the first wave of 64-bit ARM parts is not going after the high-end market.
Is 64-bit support on entry-level SoCs just a gimmick?
This trend raises a rather obvious question – are low end ARMv8 parts just a marketing gimmick, or do they really offer a significant performance gain? There is no straight answer at this point. It will depend on Google and chipmakers themselves, as well as phonemakers.
Qualcomm announced its first 64-bit part late last year. The Snapdragon 410 won’t turn many heads. It is going after $150 phones and it is based on Cortex A53 cores. It also has LTE, which makes it rather interesting.
MediaTek is taking a similar approach. Its quad-core MT6732 and octa-core MT6752 parts are Cortex A53 designs, too. Both sport LTE connectivity.
Qualcomm and MediaTek appear to be going after the same market – $100 to $150 phones with LTE and quad-core 64-bit stickers on the box. Marketers should like the idea, as they’re getting a few good buzzwords for entry-level gear.
However, we still don’t know much about their real-world performance. Don’t expect anything spectacular. The Cortex A53 is basically the 64-bit successor to the frugal Cortex A7. The A53 has a bit more cache, 40-bit physical addresses and it ends up a bit faster than the A7, but not by much. ARM says the A7 delivers 1.9DMIPS/MHz per core, while the A53 churns out 2.3DMIPS/MHz. That puts it in the ballpark of the good old Cortex A9. The first consumer oriented quad-core Cortex A9 part was Nvidia’s Tegra 3, so in theory a Cortex A53 quad-core could be as fast as a Tegra 3 clock-for-clock, but at 28nm we should see somewhat higher clocks, along with better graphics.
That’s not bad for $100 to $150 devices. LTE support is just the icing on the cake. Keep in mind that the Cortex A7 is ARM’s most efficient 32-bit core, hence we expect nothing less from the Cortex A53.
The Cortex A57 conundrum
Speaking to CNET’s Brooke Crothers, ARM executive vice president of corporate strategy Tom Lantzsch said the company was surprised by strong demand for 64-bit designs.
“Certainly, we’ve had big uptick in demand for mobile 64-bit products. We’ve seen this with our [Cortex] A53, a high-performance 64-bit mobile processor,” Lantzch told CNET.
He said ARM has been surprised by the pace of 64-bit adoption, with mobile parts coming from Qualcomm, MediaTek and Marvell. He said he hopes to see 64-bit phones by Christmas, although we suspect the first entry-level products will appear much sooner.
Lantzsch points out that even 32-bit code will run more efficiently on 64-bit ARMv8 parts. As software support improves, the performance gains will become more evident.
But where does this leave the Cortex A57? It is supposed to replace the Cortex A15, which had a few teething problems. Like the A15 it is a relatively big core. The A15 was simply too big and impractical on the 32nm node. On 28nm it’s better, but not perfect. It is still a huge core and its market success has been limited.
As a result, it’s highly unlikely that we will see any 28nm Cortex A57 parts. Qualcomm’s upcoming Snapdragon 810 is the first consumer oriented A57 SoC. It is a 20nm design and it is coming later this year, just in time for Christmas as ARM puts it. However, although the Snapdragon 810 will be ready by the end of the year, the first phones based on the new chip are expected to ship in early 2015.
While we will be able to buy 64-bit Android (and possibly Windows Phone) devices before Christmas, most if not all of them will be based on the A53. That’s not necessarily a bad thing. Consumers won’t have to spend $500 to get a 64-bit ARM device, so the user base could start growing long before high-end parts start shipping, thus forcing developers and Google to speed up 64-bit development.
If rumors are to be believed, Google is doing just that and it is not shying away from small 64-bit cores. The search giant is reportedly developing a $100 Nexus phone for emerging markets. It is said to be based on MediaTek’s MT6732 clocked at 1.5GHz. Sounds interesting, provided the rumour turns out to be true.
Can AMD Lead?
He is one of the drivers behind AMD’s transformation, with the ultimate goal of turning the chipmaker into a new organization that is not so heavily dependent on the PC market. John confirmed that the company is on the road to achieve a huge milestone in its transition plans, generating approximately 50 percent of its revenue from the non-PC market by the end of 2015.
The time for the talk could not been better, as the market reacted positively to AMD’s Q1 earnings and at press time the stock was at $4.14, up $0.45 or 12.06 percent which is a huge jump for a tech stock. Keep in mind that many tech stocks have been bearish over the last four weeks, with several massive selloffs, especially in software and internet companies.
AMD fighting back in CPU space
We covered numerous topics from desktops, notebooks and tablets strategy all the way to the server, semi-custom APUs and of course the graphics market.
John said that leadership in the graphics sector is critical in AMD’s strategy, none more so than in the PC space where AMD wants to use their performance APU’s to compete with Intel’s Core i3 and Core i5 processors in the lucrative mainstream market. This is what AMD wants to address with Kaveri and to some extent with Kabini APUs.
AMD has high hopes for its upcoming server parts where they just launched their first ARM 64-bit product for the dense server space, where AMD expects to be a leader. On the other side of the spectrum the frugal AM1 platform launched a few weeks ago and it is getting very positive reviews. The first Kaveri parts have been on sale for a while, although we would like to see more desktop SKUs, not to mention mobile Kaveri APUs, including ULV variants.
Semi-custom APUs are blurring the line between AMD’s traditional product classes, but sales appear to be good, with more than 12 million Xbox One and PlayStation 4 consoles in the wild.
Phenomenal discrete GPU sales
Byrne is quietly confident when it comes to the GPU market, having just seen very strong sales in the performance and enthusiast high end segments of the market. The surge was driven by competitive products, great games and bundles, even with the cryptocurrency craze which was more or less a fluke for AMD.
The company remains committed to the GPU market, and expects to bring the successful R9 / R7 architecture further down into the mainstream price points in 2014, with similar traction. This means AMD will continue the fight against Nvidia in desktop and notebook GPU markets, while at the same time taking on Intel on desktop and notebook side with new APUs.
AMD thinks that the mix of great gaming performance, HSA, Mantle, Open CL, compute performance and some cool technologies like facial recognition can boost its position in the GPU market. This is just one part of the magic potion that is really starting to work for AMD, but it’s good to know that when it comes to graphics and gaming, AMD will stay committed to these markets in 2014 and beyond.
Enthusiasts need not worry. Although the company is reinventing itself and pursuing non-PC revenue streams, AMD will still be there to cater to their needs.
Can AMD Grow
AMD posted some rather encouraging Q1 numbers last night, but slow PC sales are still hurting the company, along with the rest of the sector.
When asked about the PC market slump, AMD CEO Rory Read confirmed that the PC market was down sequentially 7 percent. This was a bit better than the company predicted, as the original forecast was that the PC market would decline 7 to 10 percent.
Rory pointed out that AMD can grow in the PC market as there is a lot of ground that can be taken from the competition. The commercial market did better than expected and Rory claims that AMD’s diversification strategy is taking off. AMD is trying to win market share in desktop and commercial segments, hence AMD sees an opportunity to grown PC revenue in the coming quarters. Rory also expects that tablets will continue to cannibalize the PC market. This is not going to change soon.
Kaveri and Kabini will definitely help this effort as both are solid parts priced quite aggressively. Kabini is also available in AMD’s new AM1 platform and we believe it is an interesting concept with plenty of mass market potential. Desktop and Notebook ASPs are flat which is something that the financial community really appreciated. It would not be so unusual that average selling prices were down since the global PC market was down.
Kaveri did well in the desktop high-end market in Q1 2014 and there will be some interesting announcements in the mobile market in Q2 2014 and beyond.
AMD, Intel & nVidia Go OpenGL
AMD, Intel and Nvidia teamed up to tout the advantages of the OpenGL multi-platform application programming interface (API) at this year’s Game Developers Conference (GDC).
Sharing a stage at the event in San Francisco, the three major chip designers explained how, with a little tuning, OpenGL can offer developers between seven and 15 times better performance as opposed to the more widely recognised increases of 1.3 times.
AMD manager of software development Graham Sellers, Intel graphics software engineer Tim Foley and Nvidia OpenGL engineer Cass Everitt and senior software engineer John McDonald presented their OpenGL techniques on real-world devices to demonstrate how these techniques are suitable for use across multiple platforms.
During the presentation, Intel’s Foley talked up three techniques that can help OpenGL increase performance and reduce driver overhead: persistent-mapped buffers for faster streaming of dynamic geometry, integrating Multidrawindirect (MDI) for faster submission of many draw calls, and packing 2D textures into arrays, so texture changes no longer break batches.
They also mentioned during their presentation that with proper implementations of these high-level OpenGL techniques, driver overhead could be reduced to almost zero. This is something that Nvidia’s software engineers have already claimed is impossible with Direct3D and only possible with OpenGL (see video below).
Nvidia’s VP of game content and technology, Ashu Rege, blogged his account of the GDC joint session on the Nvidia blog.
“The techniques presented apply to all major vendors and are suitable for use across multiple platforms,” Rege wrote.
“OpenGL can cut through the driver overhead that has been a frustrating reality for game developers since the beginning of the PC game industry. On desktop systems, driver overhead can decrease frame rate. On mobile devices, however, driver overhead is even more insidious, robbing both battery life and frame rate.”
The slides from the talk, entitled Approaching Zero Driver Overhead, are embedded below.
At the Game Developers Conference (GDC), Microsoft also unveiled the latest version of its graphics API, Directx 12, with Direct3D 12 for more efficient gaming.
Showing off the new Directx 12 API during a demo of Xbox One racing game Forza 5 running on a PC with an Nvidia Geforce Titan Black graphics card, Microsoft said Directx 12 gives applications the ability to directly manage resources to perform synchronisation. As a result, developers of advanced applications can control the GPU to develop games that run more efficiently.
AMD’s Kaveri Coming In Q4
AMD really needs to make up its mind and figure out how it interprets its own roadmaps. A few weeks ago the company said desktop Kaveri parts should hit the channel in mid-February 2014. The original plan called for a launch in late 2013, but AMD insists the chip was not delayed.
Now though, it told Computerbase.de that the first desktop chips will indeed appear in late 2013 rather than 2014, while mobile chips will be showcased at CES 2014 and they will launch in late Q1 or early Q2 2014.
As we reported earlier, the first FM2+ boards are already showing up on the market, but at this point it’s hard to say when Kaveri desktop APUs will actually be available. The most logical explanation is that they will be announced sometime in Q4, with retail availability coming some two months later.
Kaveri is a much bigger deal than Richland, which was basically Trinity done right. Kaveri is based on new Steamroller cores, it packs GCN graphics and it’s a 28nm part. It is expected to deliver a significant IPC boost over Piledriver-based chips, but we don’t have any exact numbers to report.
AMC Goes To The Clouds
Applied Micro Circuits has released its cloud chip which takes networking and computing and crams it all onto one SoC.
The X-Gene server on a chip, is being billed as the first 64-bit-capable ARM-based server in existence. According to the company it is the first chip to contain a software-defined network (SDN) controller on the die that will offer network services such as load balancing and ensuring service-level agreements on the chip.
Paramesh Gopi, president and CEO of Applied Micro, said that these new chips have now made it past the prototype stage and are being used by Dell and Red Hat. Gopi expects physical servers containing the X-Gene to hit the market by the end of this year.
The chip is manufactured at 40 nanometers and has eight 2.4 GHz ARM cores, four smaller ARM Cortex A5 cores running the SDN controller software, four 10-gigabit ethernet ports, and various ports that can support more Ethernet, SSDs, accelerator cards such as those from Fusion-io or SATA drives.
The cost of ownership, which includes power requirements are about half of that of a comparable x86 product, but wouldn’t discuss actual power consumption, the company claims.
