Intel Skylake GT4e GPU is 50 percent more powerful than Broadwell GT3e

In a platform slide, Intel claims that the GT4e GPU, the fastest GPU of the Skylake platform, has a 50 percent higher score than the GT3e, Broadwell’s most powerful GPU. Intel bases itself on a 3DMark score of a Skylake chip with a TDP of 45W versus a 47W Broadwell CPU.

Intel claims to have measured the 50 percent increase in performance on both 3DMark Vantage and 3DMark 11, in otherwise identical system configurations. That is stated in a platform slide that has appeared on the AnandTech forum. Earlier rumors indicate that the GT4e GPU will be part of the Skylake H-quadcores for laptops, with a TDP of up to 45W. The GT4e is Intel’s ninth generation GPU, and contains 72 eu’s and 128MB edram.

Skylake’s GT1, GT2, and GT3 GPUs will have 12, 24 and 48 EUs respectively, just like Broadwell. At Broadwell, the GT3e is the most powerful gpu, with 48 eu’s and 128MB edram. This concerns an eighth generation GPU; Intel may have made improvements to the architecture.

Intel also expects Skylake to bring improvements to the Y-series, or Core M. The consumption of a Skylake Y-soc is said to be 60 percent lower than that of the Core M 5Y10 when measured when playing 1080p content on a 2-in-1 device with an 11.6″ display. it is about ‘pre-silicon projections’, which means that the final consumption difference can turn out differently.

The first Skylake chips should appear later this year, but for the Skylake H quadcores for laptops, that may not be until early 2016. The first Broadwell mobile quadcores have yet to appear, which may be in June.
