A new leaked benchmark of what appears to be a retail version of the 11th Gen Intel Core i7-11700K shows the Rocket Lake part beat the Zen 3 based AMD Ryzen 7 5800X in both the single-threaded as well as the multi-threaded tests (in Geekbench 5).
Both the chips were running at 4.9GHz for the duration of the benchmark, with the 11700K managing a higher all-core boost of 4989MHz (vs 4937MHz on the 5800X). The Core i7-11700K scores 1,810 points in the single-core benchmark and 11,304 in the multi-core test. In comparison, the Ryzen 7 5800X falls slightly short with 1,744 and 11,067 points in the single-core and multi-core tests, respectively. A small delta in both cases but it’s enough considering that both CPUs pack the same number of cores and are running at roughly the same frequency.
As you can see, both the CPUs are octa-core parts L1I and L2 cache sizes. The L1 Data Cache is 50% larger per core on Rocket Lake at 48KB while the L3 cache is twice as much on the 5800X.
However, before making any conclusions it’s important to note that Geekbench gives a heavy weightage to crypto-based tests such as AES. In this particular benchmark, Intel’s Sunny Cove core has a major advantage compared to Zen 3. In terms of Integer and Floating Point performance, the two chips exhibit more or less identical levels of performance, with the 5800X being slightly faster in the latter and the 11700K eking out a victory in the former.
