Intel Core i5-11600KF Slower, Hotter & Less Efficient than the Ryzen 5 5600X in Leaked Benchmarks

A few synthetic benchmarks of Intel’s upcoming Rocket Lake-S budget offering, the Core i5-11600KF have surfaced, showing what the next-gen chip is capable of. Unfortunately, while the performance is a step up from its predecessor, it still fails to match up against AMD’s hex-core rival, the Ryzen 5 5600X. This is despite the fact that the latter is a 65W SKU while the 11600KF is a 125W (PL1) part, with a boost power draw of around 150-160W.

In Cinebench R15, the Ryzen 5 5600X is a significant 15% faster than the 11600K in the multi-core benchmark and a modest 6-7% faster in the single-threaded test. The deltas shrink to just 5% in Cinebench R20 for the multi-core benchmark and just a couple of percent for the single-core test. The Core i5-11400F, although offers similar performance in the single-threaded test, it falls behind by a notable margin in multi-threaded workloads.

In Cinebench R23, the Ryzen 5 5600X is a hundred points ahead of the stock 11600KF in the multi-threaded test and 74 points faster in the single-core benchmark. The Core i5-11400F which has the same TDP as the 5600X scores just 10,132 and 1,401 points in the multi and single-threaded benchmarks, respectively.

CPU-Z sees the Ryzen 5 5600X take a rather substantial lead over both the Core i5-11400F and the Core i5-11600KF in the multi-threaded bench, being more than a thousand points faster than the former and nearly 800 points faster than the latter. The single-threaded test sees the Core i5-11600KF claim its maiden victory.

Finally, we have the 3DMark scores which are more indicative of the graphics card performance than the CPU. The Core i5-11600KF still manages to take a sizable lead over the 11400F, showing that these benchmarks are more affected by the single-core performance rather than multi-threaded grunt.
