New Intel Raptor Lake benchmarks deliver some weird results

With Intel Raptor Lake on the horizon, the first benchmarks of the upcoming processors are starting to appear. Today, the mid-range Core i5-13600K was put to the test and compared to its successful Alder Lake predecessor, the Core i5-12600K.

The benchmarks produced…weird results. The Core i5-13600K blows its predecessor out of the water with an 80% improvement, but also falls flat in another test with a 26% downgrade. What does this mean for the Raptor Lake lineup?

A well-known leaker, Enthusiastic Citizen (ECSM_Official) on Bilibili, was able to get their hands on a technical sample of the Intel Core i5-13600K. This pre-production model is labeled “ES3”, meaning it is the third technical monster (ES) of the Raptor Lake CPU. Enthusiastic Citizen simulated the processor to run at the same frequency as a qualifying sample (QS), then proceeded to run tests on CPU-Z and Cinebench R23.

To accurately simulate a QS model, the tester had to crank up the clock speeds. The performance cores (P) were tuned to a frequency of 5.1GHz, while the efficiency cores (E) were boosted to 4.0GHz. While Intel has yet to release the official specs for the Core i5-13600K, ECSM says the CPU will come with six P-cores and eight E-cores, making a total of 14 cores and 20 threads. This is an upgrade of the Intel Alder Lake offering with 10 cores and 16 threads.

As far as the benchmark results are concerned, there is certainly a slight difference here. In the CPU-Z benchmark, the Intel Core i5-13600K performed very well across the board, with 830 points in single-core and 10,031 points in multi-core versus the 768 and 5,590 points achieved by the Core i5-12600K. As noted by VideoCardz, this equates to an 8% upgrade in single-core and a massive 79% upgrade in multi-core operations. Of course, an improvement is to be expected, but the 79% gain seems almost too optimistic to be true.

The Cinebench R23 test is where it gets even more confusing. The Core i5-13600K scored 1,387 points in single-core and 24,420 in multi-core tests. While the multi-core improvement is still there, albeit less (40% vs. 79%), the single-core test was definitely a disappointment, resulting in a 26% downgrade. The tester did not explain this huge discrepancy between the benchmarks.


Since the benchmark results are everywhere, what does that mean for the Intel Core i5-13600K? Will it be a multi-tasking beast that falls flat on single-core tasks? It seems unlikely. It’s early days and we’re dealing with technical samples, so there’s no telling if these test results are accurate. If so, that means Intel should go back and try to address that problem.

Such a weird discrepancy has no place in mass production, so if it keeps showing up in further benchmarks, let’s hope Intel fixes it before the CPUs hit the shelves. The last rumored release date for Intel Raptor Lake is in October, so time is running out.
