Intel Releases 16GB Xeon Phi
Intel has announced five Xeon Phi accelerators including a high density add-in card while upping memory capacity to 16GB.
Intel has managed to get its Xeon Phi accelerator cards to power the Tianhe-2 cluster to the summit of the Top 500 list, however the firm isn’t waiting around to bring out new products. At the International Supercomputing show, Intel extended its Xeon Phi range with five new products, all of which have more than one TFLOPS double precision floating point performance, and the Xeon Phi 7120P and 7120X cards, which have 16GB of GDDR5 memory.
Intel’s Xeon Phi 7120P and 7120X cards have peak double precision floating point performance of over 1.2 TFLOPS, with 352GB/s bandwidth to the 16GB of GDDR5 memory. The firm also updated its more modest Xeon Phi 3100 series with the 3120P and 3120A cards, both with more than one TFLOPS of double precision floating point performance and 6GB of GDDR5 memory with bandwidth of 240GB/s.
Intel has also brought out the Xeon Phi 5120D, a high density card that uses mini PCI-Express slots. The firm said that the Xeon Phi 5120D card offers double precision floating point performance of more than one TFLOPS and 8GB of GDDR5 memory with bandwidth greater than 300GB/s.
That Intel is concentrating on double precision floating point performance with its Xeon Phi accelerators highlights the firm’s focus on research rather than graphics rendering or workstation tasks. However the firm’s ability to pack 16GB into its Xeon Phi 7100 series cards is arguably the most important development, as larger locally addressable memory means higher resolution simulations.
Intel clearly seems to believe that there is significant money to be made in the high performance PC market, and despite early reservations from industry observers the firm seems to be ramping up its Xeon Phi range at a rate that will start to give rival GPGPU accelerator designer Nvidia cause for concern.
AMD Touts Its Memory Architecture

Comments Off on AMD Touts Its Memory Architecture
AMD has said the memory architecture in its heterogeneous system architecture (HSA) will move management of CPU and GPU memory coherency from the developer’s hands down to the hardware.
While AMD has been churning out accelerated processing units (APUs) for the best part of two years now, the firm’s HSA is the technology that will really enable developers to make use of the GPU. The firm revealed some details of the memory architecture that will form one of the key parts of HSA and said that data coherency will be handled by the hardware rather than software developers.
AMD’s HSA chips, the first of which will be Kaveri, will allow both the CPU and GPU to access system memory directly. The firm said that this will eliminate the need to copy data to the GPU, an operation that adds significant latency and can wipe out any gains in performance from GPU parallel processing.
According to AMD, the memory architecture that it calls HUMA – heterogeneous unified memory access, a play on unified memory access – will handle concurrency between the CPU and GPU at the silicon level. AMD corporate fellow Phil Rogers said that developers should not have to worry about whether the CPU or GPU is accessing a particular memory address, and similarly he claimed that operating system vendors prefer that memory concurrency be handled at the silicon level.
Rogers also talked up the ability of the GPU to take page faults and that HUMA will allow GPUs to use memory pointers, in the same way that CPUs dereference pointers to access memory. He said that the CPU will be able to pass a memory pointer to the GPU, in the same way that a programmer may pass a pointer between threads running on a CPU.
AMD has said that its first HSA-compliant chip codenamed Kaveri will tip up later this year. While AMD’s decision to give GPUs access to DDR3 memory will mean lower bandwidth than GPGPU accelerators that make use of GDDR5 memory, the ability to address hundreds of gigabytes of RAM will interest a great many developers. AMD hopes that they will pick up the Kaveri chip to see just what is possible.
Intel’s Pentium Getting Updated
Intel is going to update its desktop Pentium family with several slightly faster Ivy Bridge-based processors.
According to CPU World the chips should hit the shops in the second quarter of 2013 which is a quarter after January’s refresh of budget desktop families, and one quarter before the launch of Haswell. The new chips have the original titles of Pentium G2030, G2030T, G2120T and G2140. They will have two cores, but lack Hyper-Threading technology, and can run two threads before getting all confused.
Both the G2000 and G2100 series CPUs support only basic features, like Intel 64 and Virtualization. They do integrate HD graphics which are clocked at 650 MHz and dual-channel memory controller, that supports DDR3-1333 on the G2030 and the G2030T, and up to DDR3-1600 on the G2120T and the G2140.
Pentium G2030T and G2120T are low-power models, replacing G2020T and G2100T but are clocked 100 MHz higher, that is at 2.6GHz and 2.7GHz respectively. However they still fit into 35 Watt thermal envelope. Pentium G2030 and G2140 mainstream microprocessors will be faster than “T” SKUs, and they will have 57 per cent higher TDP. Intel expects these to replace the G2020 and G2130 SKUs. The G2030 will run at 3 GHz. The G2140 will operate at 3.3 GHz. No word on prices yet.
AMD Goes Richland
There have been more than enough leaks dealing with Richland, AMD’s successor to the Trinity powered Virgo platform, and we even had a chance to see some leaks regarding its successor, codenamed Kaveri. As you may already know, Richland is planned to last through 2013 and it is clear that this is very important chip for AMD.
Based on the Piledriver architecture and built using 32nm technology, Richland will feature an integrated GPU that will be upgraded to Radeon HD 8000 series, a generation ahead of Trinity. As you know, there has been a lot of leaks regarding the Richland parts and the quad-core A10-6800K with Radeon HD 8670D graphics is expected to pack quite a punch. Best of all, Richland will still use the same FM2 socket.
According to our sources, the NDA will be lifted on 12th of March, 8am EST, and we are sure that we will see at least a couple of reviews as well as some additional info regarding the price and the availability date.
Quantum Computing Making Strides
Researchers at the University of Innsbruck in Austria have managed to transfer quantum information from an atom to a photon, which is being seen as a breakthrough in the making of quantum computers.
According to Humans Invent the breakthrough allows quantum computers to exchange data at the speed of light along optical fibres. Lead researcher on the project Tracy Northup said that the method allows the mapping of quantum information faithfully from an ion onto a photon.
Northup’s team used an “ion trap” to produce a single photon from a trapped calcium ion with its quantum state intact using mirrors and lasers. No potential cats were injured in the experiment. The move enables boffins to start to play with thousands of quantum bits rather than just a dozen or so. This means that they can get a computer to do specific tasks like factoring large numbers or a database search, faster.
AMD Debuts R5000
AMD has released its Firepro R5000 graphics card that has video over IP capabilities.
AMD typically promotes its workstation class Firepro cards using CAD/CAM software, however this time the company is relying on remote viewing as the big selling point for its latest workstation graphics card. AMD’s Firepro R5000 has a GPU that uses its Graphics Core Next (GCN) architecture and Teradici PC video over IP technology to send graphics output over the network.
AMD used its Pitcarin GPU coupled to 2GB of GDDR5 memory in the Firepro R5000. However it isn’t AMD’s GPU that is the big selling point of the Firepro R5000 but rather Teradici’s Tera2240 chip that encrypts display output before sending it out on the network, while supporting up to 60fps (frames per second).
AMD’s Firepro R5000 is intended to be used in render farms, with each final image being sent over an IP network to the end host, and the firm claims that the technology can be used in education, financial and media environments.
The Firepro R5000 is a single slot graphics card that has two mini Displayport outputs that can drive two 2500×1600 displays, however it can also drive a further four remote displays at 1920×1200 resolution by sending data over its RJ45 Ethernet port.
Both AMD and Teradici talked up the low configuration overheads of the Firepro R5000.
Intel’s Core i7 3940XM Said To Be Fast
Comments Off on Intel’s Core i7 3940XM Said To Be Fast
The fastest Core i7 for notebooks currently available is the Core i7 3940XM, with four cores working at 3GHz by default and 3.9GHz in its turbo mode. It has a massive 8MB of cache and fits the 55W TDP envelope. It costs an arm, a leg and a few other organs of your choice, as its official price sits at $1096.
As of Q3 2013, the Core i7 3940XM will cease to be the fastest kid on the block. The Haswell replacement is right around the corner and the name of the new market leader is Core i7 4930MX. The “X” stands for Extreme Edition, while M means that the processor comes from the M-line of processors. We mentioned the H-line of processors here and the only main difference is that H comes GT3 graphics while Intel HD graphics 4600, Intel HD graphics 4×00 for GT2.
The Core i7 4930XM (yes the letters have changed the place from Ivy Bridge MX to XM with Haswell) is a quad-core with eight threads, 3GHz core clock, 3.9GHz maximum single core turbo, 3.8GHz max dual-core turbo and an impressive 3.7GHz max quad-core turbo clock.
The graphics core of choice Intel’s new GT2 HD graphics core which works between 400 and 1350MHz, but we are not aware of the number of graphics cores inside at this point. The fastest supported memory is rather disappointing, DDR3 or DDR3L 1600, and we expected a higher number here.
Intel Makes Changes To Haswell
Intel has started dividing its mobile market segments into processors lines, where the Y processor line goes up to 11.5W TDP, U line covers chips in the 15W to 25W range, while the M line covers 37W, 47W as well as 57W TDP space, with two to four cores and graphics up to GT2.
The high performance H processor line is yet another BGA package processor line that also aims for 37W, 47W and 57W TDPs, with quad-core processors and up to GT3 graphics with on-package cache memory.
Intel expects that high performing gaming and workstation PCs will go use these processors and they fit some thick clamshell designs, no Ultrabooks with 57W unless you would want to use one for welding.
Intel currently doesn’t detail the processor number and the number of SKUs but it is obvious that they will end up with quad-core Core i7 branding for QC1+ and QC2+ market segments.
Toshiba To Offer A 20-megapixel Image Chip
Comments Off on Toshiba To Offer A 20-megapixel Image Chip
Toshiba is gearing up for to offer a 20-megapixel image sensor for digital cameras that it says will be the highest resolution of its kind.
The Tokyo-based firm said the new chips will be able to support capturing 30 frames per second at full resolution. They will also be able to shoot video at 60 frames per second at 1080P or 100 frames at 720P.
Toshiba said it will begin shipping samples of the new CMOS chips in January, with mass production to begin in August of 300,000 units monthly. Toshiba is best known in components for its NAND flash memory, which it develops with partner SanDisk, but is also a major manufacturer of LSI and other semiconductors.
Digital point-and-shoot cameras are steadily falling in price, squeezed between brutal competition among manufacturers and the increasing threat of smartphones and mobile devices. While the number of pixels a camera can capture is not always a direct measure of the overall quality of its images, it is a key selling point to consumers.
The image resolution of top-end smartphones now often meets or exceed that of digital cameras. The Nokia 808 PureView launched earlier this year has a 41-megapixel image sensor.
The Japanese manufacturer said it has increased the amount of information pixels in the new chip can store compared to its previous generation of CMOS, producing better overall images. It has also reduces the size of pixels – the new 20-megapixel version has individual pixels that measure 1.2 micrometers, down from 1.34 micrometers in its 16-megapixel product.
Intel’s Haswell Goes 13W
Intel’s Haswell Y-series processors as we said a few weeks ago have yet launch. The current plan is to launch two Ivy SKUs in Q1 2013, both dual-cores, and later in 2013 Intel plans to replace them with Haswell Y series parts, with even lower TDP.
The faster one is called Core i7 3689Y and has two cores and two threads, as well as a base clock of 1.5GHz. With the help of Intel Turbo Boost 2.0, the top single-core turbo clock is an impressive 2.6GHz, while the maximum dual-core turbo clock stops at 2.4GHz, which is still impressive. This core comes with Intel HD graphics 4000 clocked between 350MHz and 860MHz with turbo.
This new core supports both DDR3 and DDR3L at 1600MHz, has 4MB of cache and impressively low 13W TDP. We have explained that SDP stands for Standard Dissipation Power and Intel expect it to be at 7W for this part.
The runner up is called Core i5 3439Y and has the same two cores and two threads with 1.5GHz base clock, but the single core turbo clock stops at 2.3GHz, while the dual-core top clock is 2.10GHz. The graphics speed, TDP and memory support remain the same, but there is a difference in cache size. Core i5 3439Y comes with 3MB instead of 4MB for Core i7 Y series 3689Y part.
