Today we finally have a 5th generation Core i7 processor on the test bed, as we take a close look at the Core i7-5775C. Based on the Broadwell microarchitecture, this new 14nm socketed processor features Intel’s most advanced integrated graphics solution yet, in fact it is the most powerful iGPU we have seen to date...
Last month we got our first look at Intel’s new ‘Braswell’ system-on-chip solutions in the form of the Pentium N3700 and Celeron N3050B. These new SoCs used the 14nm process and featured Intel’s new Airmont CPU cores. When compared to the company’s 22nm Silvermont microarchitecture Braswell promised to be more efficient, though the real headline was the greatly improved 3D performance. That review touched on the fact that setbacks in developing the 14nm process delayed the arrival of the desktop ‘Broadwell’ parts, especially the high performance variants. Although supporting Z97 motherboards arrived over 6 months ago now, we are yet to see the accompanying Broadwell parts.  Like we saw with Braswell, Broadwell is a 14nm die shrink, though in this case a shrink of Haswell which was built using the 22nm process. Naturally moving to a smaller process results in a smaller die and lower power consumption. However as is often the case with Intel’s ‘Tick’ updates, a few minor tweaks have been applied. The advantage of this minor update means that it is compatible with the existing LGA1150 platform, at least when using an Intel 9-series chipset that is. That said, it is possible through a BIOS update that Z87 motherboards could also support these new processors.  Intel officially announced ten new Broadwell processors on the 2nd of June 2015 and at the time handed out very limited samples, needless to say we missed out. That said, we were far from the only ones, and even today getting your hands on the now month old processor series is next to impossible. Sources that we have spoken with point to an early August availability, which is surprising given Broadwell was announced 2 months prior. Not just that, but Broadwell has been heavily delayed as it is, so we are surprised Intel decided on what appears to have been an unorganized soft launch. Anyway, whatever the case, we now know that there are almost a dozen desktop Broadwell CPUs inbound and today we have the flagship model on hand. Of the ten new models five are 65w desktop processors and five are 47w laptop processors. |

Pretty disappointing performace, hopefully skylake will deliver better results. |
