Engineering samples of upcoming processors Intel Raptor Lake Core i7-13700K and Core i5-13600K have been thoroughly tested, and the results appeared in bilibilia Chinese social media platform.
Comparing next-gen CPUs to their current-gen counterparts reveals massive performance gains, with some of the benchmarks returning up to 64% higher scores for Raptor Lake. Unfortunately, these performance gains come at a price.

Today’s round of juicy Raptor Lake leaks comes from ExtremePlayer on Bilibili, who posted a new video featuring the upcoming CPUs. ExtremePlayer previously reviewed the flagship Core i9-13900K, and now, moved on to review and compare the two mid-range models in the Raptor Lake-S lineup.
The processors, like Intel Alder Lake, feature a hybrid core configuration with a combination of Raptor Cove performance cores and Gracemont efficiency cores. The Core i7-13700K is said to come with 16 cores (eight P cores and 8 E cores) and 24 threads, while the Core i5-13600K serves up 14 cores (6 P cores, 8 E cores) and 20 threads. Intel Raptor Lake is rumored to offer some massive clock speeds, with boost clocks said to hit over 5.8GHz, but that’s on the Core i9-13900K – the Core i7-13700K is expected to max out at 5.4 GHz Unfortunately, these engineering samples have failed to achieve such high numbers, but they still outperformed their predecessors by a wide margin.
The Intel Core i7-13700K tested in the video was clocked at up to 5.3GHz, while the Core i5-13600K maxed out at 5.1GHz. Both models were tested twice, once with DR4-3600 memory, and then again with DDR5-5200, to compare the effect of DDR5 RAM on the performance of Intel’s next-generation CPUs. Recent benchmarks showed that Intel Raptor Lake could finally make DDR5 memory shine, and today’s leak just goes to show.
Several benchmarks were used for testing purposes, but most of them gave similar results. The Core i7-13700K appears to offer up to a 10% performance boost in single-threaded operations, but in a multi-core environment the gains are really intense. In general, an improvement of about 30-35% can be seen, but some of the tests offered a performance gain of up to 64% when the Core i7-13700K was compared to the current generation Core i7-12700KF. In a 7-Zip test, the win was even bigger, with a staggering 164.84% increase over the Alder Lake processor.
The lower-tier Core i5-13600K also managed to leave its predecessor in the dust, with smaller single-threaded gains (around five to eight percent), but, once again, massive numbers in multi-threaded operations. On average, the Core i5-13600K appears to be up to 40% better than the Core i5-12600K when tested with DDR5 RAM.
These benchmarks once again prove that DDR5 RAM might finally get its chance to shine. Until now, the adoption of DDR5 has been quite slow due to how expensive these memory kits have been. Now, with these performance improvements shown by Intel Raptor Lake, and with AMD Zen 4 using DDR5 exclusively, we can bet that the market will soon be flooded with some of the best DDR5 RAM.
The supposed performance increase comes at a high cost to power consumption, as pointed out by VideoCardz. The Intel Core i7-13700K reached a power consumption of up to 244 watts, which is really high, especially when compared to the Alder Lake Core i7-12700K with 188 watts. The Core i5-13600K also saw a similar boost: 178 watts vs. 148 watts.
While the results are exciting, it’s still early days. We’ve been seeing more and more Intel Raptor Lake benchmark results popping up recently, but until the finished product gets into the hands of early reviewers, we won’t know its full potential. That said, and with a healthy helping of skepticism, it certainly looks like Intel’s 13th Gen CPUs could become true multi-core beasts.
