The Intel i5-13600K ES3 Upto 40% Faster than Last Generation

Intel’s upcoming generation of CPUs will be based off of the ‘Intel 7 process‘ which is 10nm process node, carrying the codename ‘Raptor Lake‘. The i5-13600K ES3 (Third Engineering Sample) from the upcoming Raptor Lake series has been allegedly benchmarked running at the same frequency as the QS (Qualfication Sample). 

According to ECSM_Official from Bilibili, the processor has been fine tuned to run at the same speeds as the QS. The actual ES3 variant has the Performance Cores clocked at 5.1/4.9 GHz whereas the Efficient Gracemont cores are running at 3.9 GHz. In the QS sample, these speeds are a bit higher so ECSM slightly overclocked the Performance Cores to 5.1 GHz and the smaller Efficient cores to 4.0 GHz to match the QS sample.

As you can see in the CPU-Z screenshot above, the i5-13600K features 6 Performance Cores and 8 Efficiency Cores for a total of 14 Cores/20 Threads which is higher than the Alder Lake based i5-12600K’s 10 Cores/16 Threads. Intel’s big.LITTLE hybrid CPUs don’t feature hyperthreading on the E-Cores, that’s why this CPU only has 20 threads.


Note on the CPU | ECSM

The total power consumption is about 173W while the CPU core voltage is at 1.31V, showing there is a lot of room for more efficiency. ECSM states that the final release variant may have TDP of around 160W which is 10W higher than the i5-12600K’s Maximum Turbo Power of 150W

Performance breakdown

Moving on to the actual performance of this chip, the i5-13600K scores 24420 points in the Multi-Core test and 1387 points in the Single-Core test inside Cinebench. The i5-12600K scores 17660 and 1918 points in the same test, respectively. So, the 13th Gen CPU is 38% faster in Multi-Core, but 27% slower in Single-Core than its 12th Gen counterpart. This inconsistency is yet to be explained.

CPU-Z puts the i5-13600K 27% faster than the Ryzen 9 5950X in Single-Core (830 vs 648) testing and 15% slower in Multi-Core (10031 vs 11906) tests. This shows that Zen 4 may still have the lead in multi-threaded tasks however being an ES3 sample, the i5-13600K is expected to show improvement upon final release. But, due to the discrepancy in the Cinebench benchmarks, take these leaks with a grain of salt.
