Intel Rocket Lake-S makes another appearance on a benchmark website.
Intel 11th Gen Core aka “Rocket Lake-S”
Last month we saw the first Rocket Lake-S engineering sample running 3DMark software. That sample was a six-core model with hyperthreading enabled. Today we are reporting on an 8-core model with 16-threads enabled.
But first lets recap what we know about Rocket Lake-S so far. This is the upcoming Intel mainstream desktop architecture designed for the LGA1200 socket. Some motherboard makers have already confirmed that Rocket Lake will be compatible with the existing 400-series motherboards. Others have indirectly advertised PCIe Gen4 hardware readiness on the Z490 series. Since Comet Lake is PCIe Gen3 only, it basically confirms support for Rocket Lake’s PCI Gen4 support.
The Rocket Lake architecture will finally put the end to Skylake-based core design. It wasn’t quite clear if Rocket will use Sunny Cove or Willow Cover core, but the new leak would suggest that Rocket Lake does actually share more with Ice Lake (Sunny Cove) than Tiger Lake (Willow Cove). This essentially puts ‘Willow Cove backport’ rumors in doubt.

Intel Rocket Lake-S will also be the first architecture to support the Xe Graphics engine. This integrated graphics processor is a similar Gen12 design we will be seeing in the upcoming mobile Tiger Lake. According to the leak, the sample tested ships with 32 Execution Units, which means 256 Unified cores in total. For comparison, Intel’s first discrete graphics based on Xe design — DG1 — is expected to feature 96 EUs, which means 768 cores.
The new engineering sample is also the first known 8-core and 16-thread SKU from the Rocket Lake series. The base clock is actually lower from the previous leak as it is now reported at 3.2 GHz — compared with a 6-core leak that’s a -8.6% difference. Unfortunately, the boost clock is not reported by Geekbench software on the public page, but it can be extracted from the source code. It is reported at 4.3 GHz, which is 200 MHz higher than the first sample. We do however have first information on the Xe graphics clock speed which is 1.15 GHz.

The Xe Graphics in this new Rocket Lake-S chip scored 6266 points in the OpenCL benchmark. This means it is actually slower than Intel UHD 630 graphics in Core i7-10700K processor (which is also an 8-core chip), which scores 6360 points, as noted by Wccftech.

We have already leaked the feature set for Rocket Lake, which brings many innovations to the Intel mainstream desktop platform, such as PCIe Gen4 support and wider DMI 3.0 interface. The most significant upgrade, however, is the Gen12 Xe-based graphics. According to the leak above, it might still need more work on the backbone before it reaches the market.
