Intel slide leak shows Coffee Lake VS Kaby Lake

With Intel’s Coffee Lake announcement just days away, the leaks are starting to roll in. Today, slides from one of Intel’s presentations appeared on the web, showing the expected performance gains the company is expecting in the jump from Kaby Lake to Coffee Lake on desktop systems.

This presentation reportedly took place as part of training for retailers in China. According to the slide, Intel’s upcoming Core i7 8700K CPU will be around 11 percent faster than the 7700K in single threaded applications and 51 percent faster in multi-threaded ones. Meanwhile, the Core i5 8600K is said to receive a 19 percent performance boost over the Kaby Lake i5 in single-threaded workloads and a 55 percent boost in multi-threaded.


Intel will be announcing Coffee Lake on Monday the 21st of August, timing its announcement with the US solar eclipse. From there, an official release is expected before the end of this year. Aside from performance improvements, Intel will also be bumping up the core counts for its mainstream processors in the wake of Ryzen.

Going forward, Intel’s 8th Gen Core i7 and Core i5 parts will utilise six cores. As usual though, Hyper Threading will be reserved for the Core i7. Meanwhile, the Core i3 will no longer be a dual-core part, instead, the Core i3 will finally join the quad-core club. Speaking of the Core i3, this chip also appeared on the performance boost slide. Up against the Core i3 7350K, Intel’s 8th Gen equivalent will be 17 percent better in single-threaded workloads and 65 percent better in multi-thread.

Here's the full set of stats from the slide:

Kaby Lake Single-thread Performance Gain (%) Multi-thread Performance Gain (%) Coffee Lake
Core i7 7700K 11 51 Core i7 8700K
Core i7 7700 18 58 Core i7 8700
Core i5 7600K 19 55 Core i5 8600K
Core i5 7400 29 61 Core i5 8400
Core i3 7350K 17 65 Core i3 8350K
Core i3 7100 16 61 Core i3 8100

KitGuru Says: That is about all we could grab from the slide leak. We don’t have to wait very long for confirmation on this either, as Intel’s announcement will be happening on Monday afternoon. Until then, let us know what you think about the leaked performance improvements in the comments!
