AMD Unveils Zen Microarchitecture, Demos Summit Ridge Performance
Taking On Broadwell-E Surprisingly, AMD chose to demonstrate a head-to-head test of Summit Ridge against the Intel Broadwell-E Core i7-6900K, which also sports 8 cores and 16 threads.

The early Zen silicon is only clocked at 3 GHz, so AMD downclocked the 6900K (3.2 GHz base and 3.7 GHz turbo) to 3 GHz to normalize the test. We aren't privy to the final Summit Ridge clock speeds, but the company indicated that some SKUs would ship with higher clock speeds when it comes to market. We advise readers to take the test with a grain of salt. AMD did not share test bed details, such as the amount of system RAM, but indicated that the systems had comparable configurations. The test consisted of a CPU-intensive multi-threaded Blender 3D rendering that scaled across all of the cores. The Summit Ridge CPU rendered the image ever so slightly faster than the Intel 6900K. The contest was close enough that, without a stopwatch, we couldn't give an accurate measurement of the speed difference, and AMD did not provide specific measurements for the test.
