Update: Extreme Player posted new updated charts, this article has been updated accordingly.
Intel Core i9-13900K up to 10% faster than i9-12900K in single-core
Intel Raptor Lake desktop processor has now been fully reviewed ahead of launch.
This sample is obviously not the production unit that will go to market in Q4 this year, but a qualification sample, which is often considered near identical in terms of performance. It is as close as we get to a prelaunch review of Raptor Lake. The sample is a 24-core and 32-thread CPU with power limits set to 125W and 250W (MTB), confirming that this is indeed the K-series SKU.
Based on the CPU-Z data shared by the reviewer from China (Extreme Player), this sample has identical clock speeds to the processor that appeared two days ago over at Geekbench. That’s a base clock of 3.0 GHz and boost in 5.5 GHz to 5.7 GHz range (depending on the boost technology).
The processor was tested on ASUS ROG Z690 Extreme motherboard with DDR5 memory at 6400 MT/s. The system was also equipped with GeForce RTX 3060 Ti graphics, 1500W power supply and Thermalright AIO Frozen Magic 360 cooling solution.
The reviewer claims that the 13900K is on average 10% faster in single-core tests than 12900KF and up to 35% faster in multi-threaded workloads. Results depend on the test, but Raptor Lake appears to go as fast as 46.34% in multi-core CPU-Z than Alder Lake CPU, but also 22% in Geekbench 5 MT.
The reviewer conveniently put all benchmark results in a single chart, clearly showing that in all but one test, Raptor Lake is indeed faster.
One must note, however, that Raptor Lake’s performance boost in mainly coming from higher clocks. Both processors tested at the same frequency reach almost identical performance in CPU-Z test:
There is also a question of how much thermal efficiency is required from the CPU cooler. The 13900K tested in Intel’s own XTU tool reached 100°C peak temperature and began to throttle despite using 360 AIO cooler. Furthermore, the PL4 (package) power reportedly hit as high as 420W.
Intel has not really confirmed the launch date for its 13th Gen Core series, but given the rumored timeline, it should become available around October. This means that this review is essentially a glimpse of what Raptor Lake might offer in its final production form three months from now.
