Intel Skylake Gen9 Series Graphics Architecture Unveiled 29

MojoKid writes: Intel's Skylake is here and the new architecture comprises Intel's 6th generation Core line of CPUs. In recent testing it was confirmed that Intel's Skylake-based Core i7-6700K is the company's fastest quad-core desktop processor to date. However, one thing Intel kept a tight lid on was the underlying technology of the Gen9 Intel HD Graphics engine on board Skylake, that is until now. An overview of the changes Intel made specific to Intel Gen9 graphics, notes the following among other tweaks: Available L3 cache capacity has been increased to 768 Kbytes per slice (512 Kbytes for application data). Sizes of both L3 and LLC request queues have been increased. This improves latency hiding to achieve better effective bandwidth against the architecture peak theoretical. Gen9 EDRAM now acts as a memory-side cache between LLC and DRAM. Also, the EDRAM memory controller has moved into the system agent, adjacent to the display controller, to support power efficient and low latency display refresh. Gen9 has also been designed to enable products with 1, 2, or 3 slices, each with 24 EUs per slice and 8 EUs per subslice. Finally, Gen9 adds new power gating and clock domains for more efficient dynamic power management. This can particularly improve low power media playback modes.

  • The Skylake processors might be the fastest "stock" processors released, but the "k" series processors are made for overclocking. It still turns out that the 2xxxK and the 3xxxK chips still overclock as fast or faster than the broadwell and skylake counterparts/replacements to the point that even though the skylake processors are more efficient clock for clock, the older ones overclocked to such a higher clock speed to more than makeup for those efficiency improvements.

    Although I've got Linux on my servers, I'm using Apple on the desktop (app development). The last MacBook Pro update was... lackluster, without a CPU update. I'm really hoping for Skylake and its integrated graphics, because I want the fastest laptop but without discrete graphics. The repeated disasters in the past with the discrete graphics basically melting off the motherboards, left me waiting for something like this.

    It's a nice update and good progress on the GPU architecture.
    However not very interesting considering DirectX12 support isn't very far/complete.
    And no DirectX12 features such as Conservative Rasterization are supported in the hardware.
    Looking forward for the next Intel GPU architecture that does support Conservative Rasterization.

Don't be irreplaceable, if you can't be replaced, you can't be promoted.
