New Raptor Lake Benchmarks Show Dual-Core 5.8GHz Boost Clock

A new batch of Raptor Lake benchmarks have appeared on a Chinese video site, with additional information on the new architecture’s performance. Overall, things are looking promising for the successor to Alder Lake. Single-core workloads are up by 10 percent, but multi-core benchmarks are up as much as 1.5x. That’s considerably higher than what we’d normally expect for a same-node CPU architecture (both Alder Lake and Raptor Lake are built on Intel 7).

The latest benchmarks come from the video tech reviewer Extreme Player, who posted several synthetic results after testing a QS engineering sample of Intel’s latest CPU. The chip is running at a 3GHz base clock with an all-P boost clock of 5.5GHz. It also features a dual-core boost clock of 5.8GHz. This is substantially higher than the Alder Lake-based Core i9-12900K, but not nearly enough to account for some of the claimed performance improvements. Raptor Lake IPC is up substantially over Alder Lake, if these rumors are true.

It was also previously rumored that Intel was aiming to offer a 5.8GHz maximum boost clock. However, at the time it was assumed that meant single-core only. That could end up being incorrect, based on these benchmarks. Still, earlier benchmarks showed another Raptor Lake CPU hitting 5.7GHz, but on a single core. This gives us a very good indication of what Intel is aiming for with Raptor Lake, as far as clocks are concerned.

ExtremePlayer compared the Core i9-13900K to the Core i9-12900K using an Asus ROG Maximus Z690 Extreme mobo, DDR5-6400 memory, and a GeForce RTX 3060 Ti. All the tests were synthetic, or based on content creation.

The Raptor Lake CPU was up to 40 percent faster in multi-core tests. For single-core tests, the delta usually hovered around 10 percent depending on the benchmark. As an example, in the oft-used Cinebench R23, Raptor Lake was 38.78 percent faster than Alder Lake in multi-core, but just 13.71 percent faster in single-core. Other tests followed a similar pattern. These numbers also sync up with the previous Geekbench scores. Those showed Raptor Lake with a seven percent advantage over Alder Lake in single core. In multi-core, though, Raptor Lake blew past its predecessor by over 30 percent.

Overall, things are looking very promising for Raptor Lake.No one was quite sure what to expect when Alder Lake launched. The new CPU used an unknown hybrid CPU architecture and Intel hadn’t exactly distinguished itself recently. Alder Lake has done well and Raptor looks as though it will offer sizeable gains, too. However, Alder Lake launched against Zen 3, which had been around for quite some time. That won’t be true for Raptor Lake, as it’s going up against an all-new Zen 4 from AMD. Therefore, despite Raptor Lake’s promising early benchmarks, it still has a steep hill ahead of it to hold onto the fastest CPU crown.
