CHIPMAKER Intel will offer five GPU SKUs in its upcoming Haswell based processors and a further two for its server chips.
Intel has been placing greater emphasis on its graphics performance in the last few generations of its chips, with Ivy Bridge finally bringing full profile OpenCL capability. Now the firm has released some more details on the GPUs that will be available with its Haswell processors, with five options for desktop and laptops that the firm claims are up to twice as fast on its favoured 3DMark benchmarks.
While Intel showed off performance figures using various versions of its favoured synthetic 3Dmark benchmark, the firm also said that its next generation GPU will support Microsoft's DirectX 11.1 and OpenGL 4.0 along with OpenCL 1.2. The firm also said it will put DRAM on the same package as the GPU.
Intel also revealed what GPUs certain processors will have. The Core i7-4650U, a 15W TDP chip for ultrabooks, will have a GT3 GPU, while the Core i7-4558U, a 28W TDP mobile chip, will have a higher performance GPU aimed at larger laptops. The firm will drop its internal GTx codenames in favour of more marketable monikers.
Before Intel plasters its HD Graphics and various other stickers on the GPUs, the firm said GT1 GPUs will be destined for processors carrying the Pentium and Celeron branding, with GT2 being the most common GPU found in processors branded as Core. Intel's GT3 and GT3e GPUs will come in three flavours for particular TDPs, with the firm using the desktop Core i7 4770K and Core i7 4770R as examples of chips with different TDPs, 84W and 65W respectively, with different GPUs and benchmark performance.
While Intel's GPUs in Haswell processors are still unlikely to be enough for gamers, it is clear that Haswell chips will provide another significant jump over Intel's previous generation GPUs, which is particularly important for laptop users who are starting to see higher resolution displays but are forced to run with integrated graphics. µ
