Intel 13th Gen Raptor Lake i9-13900 review suggests AMD Ryzen 7000 could be king

Microsoft confirmed that it will publicly release the Windows 11 22H2 feature update in the second half of this year. It will also see the hardware giants clash as both Intel and AMD are set to unveil their upcoming processor architectures. AMD is expected to release the Zen 4-based Ryzen 7000 series first, followed by Intel's 13th-gen Raptor Lake-S CPUs.

SiSoftware has decided to release an early performance preview of the upcoming Raptor Lake-S SKU. The Intel Core i9-13900 is a locked version of the i9-13900K and has been tested. The part has been tested against the previous-generation Alder Lake-S (ADL-S) Core i9-12900, the 11th-generation Rocket Lake-S (RKL-S) i9-11900K, and AMD's 12C/24T Ryzen 9 5900X (Zen 3) Compare.

We have arithmetic (integer and floating point) benchmarks where the new Raptor Lake CPUs are a huge improvement over the 12th Gen 12900 processors. In fact, in one instance, performance even doubled. It's also enough to put the Core i9-13900 ahead of Ryzen CPUs, which is impressive. The two additional smaller Gracemont core clusters on Raptor Lake seem to really help. So, the Raptor Lake i9 CPU is a 24-core, 32-thread part compared to the 16-core, 24-thread on Alder Lake.

Tested the Vector SIMD (Single Instruction Multiple Data) benchmark, and unlike the non-SIMD case, the performance of the Raptor Lake-S i9-13900 compared to Alder Lake The improvement is quite limited. The bigger takeaway is that the upcoming Intel CPU won't be able to beat the Ryzen 9 5900X, as the latter has a healthy performance lead.

Upcoming Intel chips may have a hard time competing with AMD's Zen 4 parts in SIMD workloads, as AMD brings AVX-512 with these upcoming CPUs Come.

The company stated:

For highly vectorized SIMD workloads - RPL cannot beat ADL by more than 4-6%, So it usually loses even to the AVX512 enabled RKL which has only 16 threads (compared to 32T on the RPL). This goes to show how much the AVX512 can help despite the extra power required - and here it's greatly missed.

However, AMD's Zen3 (5900X) with fewer threads (24T) but 12 big cores (vs. 8C 16c) still beats RPL by a sizeable margin, which is not good news for Intel. With AMD's upcoming Zen4 with AVX512 support, RPL could be severely beaten - possibly by as much as 2x (100%). Intel will once again have to rely on non-SIMD workloads/benchmarks (Cinebench?) to demonstrate performance leadership.
