AMD Makes Cuts
AMD has cut its third quarter revenue and gross margin forecasts citing weak demand.
AMD’s lacklustre Bulldozer processor line has left the firm desperately trying to compete with Intel in the desktop market while its more impressive accelerated processor unit (APU) range has been rebuffed by Intel’s multi-million dollar ultrabook marketing push. Now AMD has revised down its estimate of third quarter revenues, which it says will be around 10 percent lower than the previous quarter.
Even more worrying for AMD is its lower forecast for gross margin, the difference between selling an item and the cost to make it, down from 44 percent to 31 percent. Effectively AMD said its cost of doing business has risen considerably higher, although it laid most of the blame on an $100m inventory writedown.
AMD couldn’t avoid admitting the blindingly obvious and said that its writedown of inventory was due to “lower anticipated future demand for certain products”. The firm has suffered through a disappointing 2012, and earlier this year it announced a $580m loss back in April.
AMD Confirms Trinity’s New Specs
AMD has confirmed the specifications of its Trinity accelerated processor units (APUs), with the majority being quad-core units with 4MB cache.
AMD launched its mobile Trinity APUs earlier this year in a bid to cash in on “back to school” sales and now it has detailed the specification of Trinity processors that will slot into desktop systems. The firm confirmed that Trinity has moved from Socket FM1 to Socket FM2 and save for two A4 and A6 SKUs the chips will all be quad-core parts with base frequencies over 3GHz.
AMD stuck with its A4, A6, A8 and A10 branding with the dual-core A4-5300, base clocked at 3.4GHz with turbo mode pushing that up to 3.6GHz and 128 graphics cores clocked at 723MHz at the foot of AMD’s APU line-up. Next up the firm has the unlocked dual-core A6-5400K, which not only bumps the CPU clock speed by 200MHz to 3.6GHz and 3.8GHz for base and turbo modes, respectively, but increases the number of graphics cores to 192 and their frequency to 760GHz.
While AMD’s A4 and A6 Trinity processors are dual-core, the four other chips in the range are all quad-core parts, with the A8-5500 and A8-5600K sporting base clock speeds of 3.2GHz and 3.6GHz, respectively, with turbo mode boosting those to 3.7GHz and 3.9GHz, respectively. The firm has kept the number of graphics cores on both chips the same at 356 and clocked them at 760MHz, however the higher frequency on the A8-5600K means that the firm bumped up the TDP to 100W, though given it is unlocked, the factory TDP is largely academic.
AMD’s A10 chips follow in the same vein as the A8 parts, with the 65W A10-5700 part clocked at 3.4GHz, boosted to 4GHz while the 100W A10-5800K part has its clocks set at 3.8GHz and boosted to 4.2GHz. AMD has given both processors 384 graphics cores clocked at 800MHz.
AMD Officially Launches Trinity Mobile
AMD has finally and officially lifted an NDA veil off its mobile Trinity A-series APU lineup based on the 2nd-gen Bulldozer CPU core, aka Piledriver, and VLIW4 Northern Islands GPU squeezed together on a 32nm SOI die.
Architecture-wise, AMD’s Trinity combines two to four Piledriver x86 cores combined with up to 384 VLIW4 Radeon cores on a 32nm die which ends up as a 246mm2 chip with 1.303B transistors, slightly more than Llano’s 228mm2/1.178B. Since it is made in the same 32nm manufacturing process as Llano, the greatest win for Trinity are actual CPU and GPU performance improvements as well as impressive power consumption improvements when compared to Llano APUs.
Same as the FX-series desktop parts based on the Bulldozer architecture, AMD’s Trinity CPU part has a 2+1 integer/floating point design where you get two integer cores that share a single floating point scheduler. Although it appears to the OS as two cores, each Piledriver module actually has less resources than traditional core design. But with Piledriver, those Bulldozer kinks got ironed out as much as possible, improving IPC (instruction per cycle), reducing leakage, reducing CAC and giving it a slight frequency uplift.
As far as the GPU is concerned, we are looking at quite familiar Northern Islands VLIW4 part, a same one that was behind Cayman Radeon HD 6970 graphics card. Of course, the GPU has been cut down to up to 384 stream processors (organized in 6 SIMDs) with 24 texture units and 8 ROPs. The clocks have also gone down to 497MHz base clock that can “turbo” up to 686MHz.
Trinity Launching On Desktops This Summer
Comments Off on Trinity Launching On Desktops This Summer
AMD is expected to introduce its new mobile Trinity APU in a week or so and now we are hearing some timeframes for desktop parts as well.
According to Digitimes, desktop Trinity parts are coming in August, while Brazos 2.0 chips are expected in June. There is no word on Trinity ULV parts yet and we believe they will be the most interesting of the lot.
AMD’s Trinity To Have Fewer Cores
AMD’s soon to launch A10 5800K is a 100W quad-core Trinity 32nm CPU with 3.8 GHz base clock and 4.2GHz maximal clock possible with AMD turbo core dynamic overclocking technology.
The A10 5800K has 4MB of L2 cache, supports DDR3 1866, dual graphics configurations as well as AMD’s new FM2 socket. The fun part is new HD 7660D GPU that works at 800MHz and comes with 384 shader units. The current APU market leader A8 3870K that works at 3GHz has HD 6550 graphics with 400 cores running at 600MHz.
AMD claims that new Radeon cores from Trinity CPU including A10 5800K are more efficient and this is the main reason why you have fewer cores that can deliver superior performance. The other reason is that with 800MHz core clock they can probably process more data, meaning that HD 7660D of A10 5800K should end up quite a bit faster than the Llano A8 3870K.
All these Radeon cores are a key feature of the Vision Engine that accelerates GPU enabled applications. AMD also tells the world that Trinity is DirectX 11 compatible, supports Direct compute and the new A series of processors, including the A10 5800K all the way to dual-core A4 5300, should not have any issues playing Blu-ray 3D. The GPU part of Trinity supports AMD V, UVD3 as well as Open CL acceleration.
