One of the strengths of Broadwell processors generation is considered to be not only compatible with motherboards equipped with socket LGA 1150 but also the graphics system Intel Iris Pro 6200 with the type of built-in memory 128 MB eDRAM. However, integrated graphics - as the choice of enthusiasts in extremely rare cases.
Associates Legit Reviews have found that Intel left the frequency control of eDRAM memory type , which are equipped with Broadwell processors by LGA 1150. Officially, it's made for the possibility of retaining eDRAM memory frequency at values close to the regular 1800 MHz when overclocking other processor units . However, if the eDRAM memory frequency can be reduced, nothing prevents it to improve. Through experiments with processor Core i7-5775C and a new version of firmware for the motherboard Asus Z97-A our colleagues we found that the memory eDRAM can be overclocked over 2000 MHz, 2200 MHz but the line usually becomes critical - productivity falls, contrary to expectations. Interestingly, the firmware of the motherboard allows to not only raise or lower the frequency of eDRAM using the dividers, but also completely disable the memory eDRAM!
WE argue that eDRAM has a significant impact on the performance of the graphics system. It remains to wait for the new versions of the firmware to take advantage of these opportunities in the existing motherboards with chipsets Intel ninth series. In addition to Asus, Gigabyte will develop an appropriate functionality of their motherboard .
Associates HardwareLuxx.de simultaneously claim that Haswell integrated voltage regulator will be absent in Skylake and Kaby Lake processors.
