I7 7700k cinebench6/6/2023 ![]() This isn't too shocking since we're comparing 4.2-4.5GHz 4-core against 3.4-3.8GHz 6-core parts, with the 4-core part sporting an improved 6-wide superscalar architecture and other tweaks. Even when overclocked, the i7-7700K uses less power (165W under load) than the various Haswell-E/Broadwell-E processors (165-200W), thanks in part to a more power efficient platform. Obviously, overclocking the 6-core chips changes the story, but only by substantially increasing power use. In the overall ranking, the 7700K OC beats all three of the 6-core chips we tested. Also worth note is that in many of the heavily threaded benchmarks the overclocked 7700K is roughly equal to the various 6-core Haswell-E and Broadwell-E CPUs. Single-threaded performance is a clear highlight of Kaby Lake, with the stock and overclocked 7700K claiming the two top spots in Cinebench's single-threaded test. Looking at CPU performance, I'm including stock performance from all of the other processors, though you can view the overclocked performance in the main Kaby Lake hub (opens in new tab). Of particular note, the DRM means 4K Netflix streaming can only work via the integrated video ports. ![]() The 4K Netflix support also features DRM, like it or not-we should place wagers on how long it will be before someone cracks this DRM. Does that matter to desktop users? Probably not, since they'll be plugged in and most likely running a dedicated graphics card. Intel claims that laptops with Kaby Lake will get up to 9.5 hours of battery life while decoding 4K video, which is an excellent result. I'll get to those in a moment, but let's start with a short discussion of the video/graphics/multimedia performance.įirst, 4K streaming when you're using the HD Graphics 630 works really well-and CPU utilization is very low with Netflix 4K as an example. CPU and gaming performance with a dedicated graphics card is the same as before, but here I'm highlighting just the i7-7700K in the charts, with both overclocked and stock clocked performance. This is the shorter executive summary of the i7-7700K, focusing on a single product rather than the entire Kaby Lake lineup. I've already discussed all of these aspects of Kaby Lake, but never rendered a final verdict.
