Another Intel Rocket Lake Desktop CPU has leaked out within the 3DMark benchmark database but this time we are looking at 8 cores offering speeds of up to 4.30 GHz. The previous leak we covered was also for an 8 core and 16 thread part but the chip was in a far early engineering state running at clock speeds of just 1.80 GHz.

Intel Rocket Lake-S Desktop ES CPU With 8 Cores, 16 Threads & Up To 4.30 GHz Clock Speeds Benchmarked in 3DMark

It looks like Intel's Rocket Lake-S Desktop CPUs have seen a new ES revision, now offering clocks beyond 4.00 GHz. Just last month, we reported another 6 core & 12 thread processor which was running at up to 4.10 GHz clock speeds. The new chip which has been spotted by Rogame comes with a 4.30 GHz clock speed across 8 cores and 16 threads. These are still nowhere near the final clock speeds but it looks like progress is being made on Rocket Lake's development before it heads out on desktop platforms.

In terms of performance, the Intel Rocket Lake-S Desktop CPU was tested in 3DMark Firestrike and 3DMark Time Spy benchmarks. The CPU scored 4963 points in the Time Spy &18898 points in the Firestrike benchmarks. These scores in each respective benchmark are super low but that could be due to several reasons. When compared with our own results, you can see that the 8 core Rocket Lake chip doesn't even come close to the Core i5-8600K which is 6 core and 6 thread CPU. You can see the performance comparisons below:

It is possible that the maximum clock speeds are being reported but could not be operating properly. Furthermore, the overall clock speeds of Intel's 8 core Rocket Lake CPUs are still much lower than what 14nm is capable of. Considering that this is still an ES part, we advise waiting for more leaks in the coming months to extrapolate the final performance of Rocket Lake-S desktop processors.

Here's Everything We Know About The 11th Generation Rocket Lake Desktop CPUs

Intel's Rocket Lake-S desktop CPU platform is expected to feature support on LGA 1200 socket which will make its debut with Comet Lake-S CPUs although on 400-series motherboards. The Intel Rocket Lake-S processors will be launching alongside the 500-series motherboards but it has since been confirmed that LGA 1200 motherboards will offer support for Rocket Lake-S CPUs, especially given the fact that PCIe Gen 4.0 is a prominent feature of Z490 motherboards which would only be enabled with the use of Rocket Lake-S desktop CPUs.

Main features of Intel's Rocket Lake Desktop CPUs include:

Increased Performance with new processor core architectureNew Xe graphics architectureIncreased DDR4 speedsCPU PCIe 4.0 LanesEnhanced Display (Integrated HDMI 2.0, HBR3)Added x4 CPU PCIe Lanes = 20 Total CPU PCIe 4.0 LanesEnhanced Media (12 bit AV1/HVEC, E2E compression)CPU Attached Storage or Intel Optane MemoryNew Overclocking Features and CapabilitiesUSB Audio offloadIntegrated CNVi & Wireless-AXIntegrated USB 3.2 Gen 2x2 (20G)2.5Gb Ethernet Discrete LANDIscrete Intel Thunderbolt 4 (USB4 Compliant)

Once again, the reason I think that Rocket Lake is using Willow Cove cores is that Tiger Lake with the same architecture features Xe Gen 12 graphics while Ice Lake with Sunny Cove cores is using the Gen 11 GPU. It is possible that the cache is different on desktop chips but once again, that remains to be confirmed and until we see more leaks, this is up for debate.
