In a bizarre move, a VXD392 decode block is still included from Img - despite Intel's own decoder being present in the design. That being said, Imagination isn't totally out of Valleyview. By the time Intel gets to 14nm, I wouldn't be too surprised if it starts playing around with gen-graphics in a smartphone. We've expected Intel to move away from licensing Imagination's GPUs for quite a while now, and it seems like Valleyview might be the first attempt at doing just that. The big news are the four integrated Gen7 graphics engines, which I can only assume refer to Intel's EUs (Intel's HD 2500 has 6 EUs, while HD 4000 has 16 EUs). Whenever this does go into a Windows 8 tablet, the performance should be quite good. The combination of new architecture, more cores and higher max clock speeds should yield much better performance than Cedar Trail. Each core gets a hefty 512KB L2 cache, for a total of 2MB in a quad-core configuration. The SoC will feature between 1 and 4 22nm Silvermont cores (Out-of-Order Atom, new architecture) running at anywhere from 1.2GHz to 2.4GHz. Valleyview will replace Cedar Trail's SoC, although you can expect that a Clover Trail/Medfield replacement will come down the road. Today EXPreview posted a bunch of slides offering additional insight into Valleyview. Take up to four 22nm next-generation Atom cores and pair them with Intel's own Gen7 graphics (currently used in Ivy Bridge) and you've got Valleyview. It uses 1 - 2 Saltwell derived Atom CPU cores and a PowerVR SGX 545 GPU from Imagination.Īn unintentional leak a few months ago brought the codename Valleyview to light. The GPU core is expected to be the PowerVR SGX 544MP2, and clocked high enough to be competitive with the 543MP4 in Apple's A5X SoC.Ĭedar Trail is the 32nm netbook/nettop platform. The two 32nm CPU cores are based on the Saltwell design, which happens to be the same CPU core used in Intel's Medfield platform for smartphones. Clover Trail will be in ASUS' Tablet 810 as well as Acer's W510. Clover Trail is the dual-core 32nm Atom platform that will power the first generation of value x86 Windows 8 tablets (and go up against ARM based Windows RT designs).
