Intel Core i7-14700K performance and specifications leak showing up to 17% gain vs Core i7-13700K in multi-threaded benchmarks

First spotted by @9550pro on Twitter, specifications and performance of an Intel Core i7-14700K Engineering Sample (ES) have leaked on the Chinese social media site Bilibili. According to the leaked information, the Core i7-14700K ES is a 20-core/28-thread part with P and E-core boost clocks of 5.5 GHz and 4.3 GHz respectively. The CPU also reportedly has 33 MB of shared L3 cache, 2 MB of L2 cache per P-core, and 4 MB of L2 cache per E-core module.

In essence, the Core i7-14700K has 4 more E-cores, 3 MB of additional L3 cache, and a 200 MHz higher boost clock for the P-cores vs the Core i7-13700K.

More interestingly, the leak also depicts benchmark scores of the Core i7-14700K ES and compares them to the Core i7-13700K. The Core i7-14700K appears 4.74% and 16.96% faster than the Core i7-13700K in the Cinebench R23 Single-Core and Multi-Core benchmarks respectively. The Core i7-14700K ES also reportedly beats the Core i7-13700K in the 3DMark Time Spy CPU benchmark with a score of 18,593 which is 6.88% better than the 17,314 score managed by the Core i7-13700K.

Similarly, in CPU-Z single and multi-core tests, the Core i7-14700K ES supposedly outpaces the Core i7-13700K by 4.55% and 16.11% respectively.

These latest Core i7-14700K CPU-Z and Cinebench R23 results are consistent with the ones that leaked in early July. But, since the CPU in question is an engineering sample, we can expect the performance to be notably better in the retail samples.

That said, we should judgments until the Core i7-14700K officially launches and gets independently tested.
