AnandTech, during testing platforms with processors Skylake-K (model Core i7-6700K and i5-6600K) revealed an unpleasant feature. When you work with discrete graphics performance on both new items are almost always inferior to platforms generation Broadwell and Haswell. On average, the gap Skylake was at 1-3%, although in some cases, reducing the average frame rate reached 5.7%. And if compared with Broadwell processors problem can be changed on the mechanisms of the buffer module as eDRAM, why Skylake lagged Haswell, remained a mystery.
As it turned a register in Skylake processors does not work as planned. Intel is working on the problem. We are talking about the case, which is responsible for the value of the clock ring bus. Specifically, for the portion between the processor and PCI Express Graphics (PEG). ASUS explained, too, it may be due to an incorrect setting FCLK.
According to Intel's request frequency FCLK for mobile platforms is set relative to the reference generator BCLK multiplier x8 (800 MHz), and desktop platforms - x10 (1 GHz). Default manufacturers for desktop systems installed less frequency - 800 MHz.
After adjusting settings already on the new BIOS fixesFCLK to 1 GHz did not much improved the situation with the speed of Skylake with discrete graphics. Backlog from Broadwell and Haswell gone, , but it turned out to be purely symbolic advance . Related Products :
