Pre-production samples of the upcoming Intel Core i9-13900K have started making the rounds. In China, a reviewer with a sample conducted several tests, comparing the First Edition chip with the Core i9-12900KF. Overall, Raptor Lake seems to provide a big boost in multi-core performance over Alder Lake.

The i9-13900K pre-production sample video review has been posted at bilibili by Extreme Player (via video cardz). Additionally, it shows the chip operating at the same clock speeds as the latest engineering samples we saw, with the 24C/32T processor hitting operating frequencies of 5.5-5.7 GHz. According to the video, the tests were performed on a system using an Asus ROG Z690 Extreme motherboard with DDR5-6400 memory, an RTX 3060 Ti GPU, and a 1500W PSU. The CPU was cooled using a Thermalright AIO Frozen Magic 360 AIO cooler.

The test suite included many benchmarks, like Cinebench R23, CPU-Z, Geekbench, 3DMark, Blender, and AIDA64. Unfortunately, there are no game benchmarks at this time.

On average, the Intel Core i9-13900K was 10% faster than the Core i9-12900KF in single-core workloads, beating the Alder Lake chip in all AIDA64 memory write tests. However, considering the difference, it is within the margin of error. In multi-core tests, the Raptor Lake chip was 35% faster.

The video also shows each processor tested at the same clock speeds. During these tests, the scores were nearly identical, suggesting that Raptor Lake’s performance boost comes from a combination of higher clock speeds and additional electronic cores to facilitate multi-threaded workloads.

The thermals on this pre-production sample during testing were a little worrying, with the chip reaching 100°C despite the 360mm AIO CPU cooler being used. At this temperature, the processor began to throttle. According to the data collected, the power of the package reached 420 W.

KitGuru says: It looks like users will have to pay a hefty price for the extra performance that Raptor Lake brings. The high clock speeds of the upcoming chips seem to be the reason for the increase in single-core performance. However, to benefit from it, you will need a capable CPU cooler.
