Recently unveiled Intel Skylake lineup brought couple of surprises including a high 95W TDP for quad-core parts and according to Intel, this is due to a more powerful integrated graphics part inside Skylake CPUs which will offer up to 50 percent improvement over Haswell IGP.
While Intel's 6th generation Core Skylake CPUs are based on 14nm manufacturing process, a big surprise was a rather high 95W TDP for quad-core parts like Core i7-6700K and the Core i5-6600K, especially considering that Haswell 22nm Core i7-4770K and the Core i5-4670K parts had an 84W TDP.
A new leaked slide puts a bit more light on Intel's IGPs inside Skylake CPUs, which is a main reason behind such higher TDP and promises up to 50 percent higher integrated graphics performance compared to Haswell.
According to the slide, despite higher TDP, Skylake based SoCs will draw as much as 60 percent less power compared to Haswell SoC, which, according to Intel, translates to 35 percent longer HD video playback on portable devices. Intel's new IGP will use the recently mentioned eDRAM cache, which should significantly improve performance and also offer higher resolution support, including 4K (3840 x 2160) and 5K (5120 x 2880) resolutions.
Of course, these numbers for Skylake Iris Pro graphics will be more important on portable devices like notebooks while desktop market will still rely on discrete graphics parts.
