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.
