The listing has all the telltale signs of "Cypress Cove," such as 48 KB L1D cache, 512 KB per core L2 cache, and and 16 MB shared L3 cache for this 8-core/16-thread chip. "Cypress Cove" is rumored to be to be a back-port of Intel's "Willow Cove" CPU core design from its original 10 nm+ node to the 14 nm++. VideoCardz compared this "Rocket Lake-S" ES benchmark result to that of a retail Core i7-10700K, and found its single-threaded performance to be roughly 6.35 percent higher despite a 200 MHz clock-speed deficit, although for some reason, its multi-threaded performance is trailing by over 15 percent.

A plethora of Rocket Lake benchmarks is now available over at the SiSoftware database, as spotted by @momomo_us, which gives us a sneak peek of the processor's performance in comparison to the current 10th Generation Comet Lake-S offerings.

The Rocket Lake chip in question comes with eight CPU cores, 16 threads and 16MB of L3 cache. Given the identical design to the Core i7-10700K, the unnamed Rocket Lake part is likely the successor to the existing octa-core Comet Lake-S chip. Rocket Lake should be similar to Comet Lake-S in a lot of ways. For example, Rocket Lake will likely employ the 14nm process node, even if it's just for the cores; there's a rumor that Intel is implementing its Gen12 Xe intel graphics via 10nm die inside a chiplet structure.
...
Luckily, Rocket Lake may finally break away from the antiquated Skylake microarchitecture. The current speculation is that Rocket Lake will exploit the Willow Cove microarchitecture but with a slight twist. Willow Cove is designed for Intel's 10nm processors, and Rocket Lake is allegedly using 14nm CPU cores. That would mean Intel would have to backport Willow Cove to the 14nm node. Cypress Cove is the rumored codename for this backport.

Based on these newfound (and unconfirmed) benchmark results, the Rocket Lake CPU was operating at a 3.2 GHz clock speed, which we assume is the base clock. Sisoftware didn't reveal or wasn't able to pick up the processor's boost clock speed. A similar octa-core Rocket Lake chip surfaced on Geekbeench 5 with a boost clock that soared to 5 GHz. We're not certain if this is the same processor.

The Rocket Lake processor scored 729.65 Mpix/s on the processor multimedia test. Assuming that the chip was running at 3.19 GHz during the entire duration of the test, that equates to 228.73 Mpix/s per gigahertz.

According to Sisoftware's database, the average score and clock speed for a Core i7-10700K are 918.59 Mpix/s and 4.85 GHz, respectively. So the Core i7-10700K puts out 189.4 Mpix/s per gigahertz. If that's the case, the Rocket Lake chip delivered 20.8% higher Mpix/s per gigahertz than the Comet Lake part.

Sisoftware's average score for the Core i7-10700K is most likely skewed, since we suspect it takes both stock and overclocked results into consideration. We know that the Core i7-10700K has a 4.7 GHz all-core boost clock. If we use that value as reference, it works out to 195.44 Mpix/s per gigahertz on the Core i7-10700K, meaning the Rocket Lake offers only 17% better performance.

Neither method is accurate, but it at least gives us a faint idea of the performance uplift Rocket Lake may offer.

Intel is struggling with its node development and it looks like next-generation consumer systems are going to be stuck on 14 nm for a bit more. Preparing for that, Intel will finally break free from Sky Lake-based architectures and launch something new. The replacement for the current Comet Lake generation is set to be called Rocket Lake and today we have obtained some more information about it. Thanks to popular hardware leaker rogame (_rogame), we know a few stuff about Rocket Lake. Starting off, it is known that Rocket Lake features the backport of 10 nm Willow Cove core, called Cypress Cove. That Cypress Cove is supposed to bring only 10% IPC improvements, according to the latest rumors.

With 10% IPC improvement the company will at least offer some more competitive product than it currently does, however, that should be much slower than 10 nm Tiger Lake processors which feature the original Willow Cove design. It shows that backporting of the design doesn't just bring loses of the node benefits like smaller design and less heat, but rather means that only a fraction of the performance can be extracted. Another point that rogame made is that Rocket Lake will run up to 5 GHz in boost, and it will run hot, which is expected.
