The Intel Rocket Lake-S architecture will be presented later this year as the successor to Comet Lake-S, a generation that was officially released just a few days ago and which, as we have told you in previous articles, represents a very small evolution in front of Coffee Lake Refresh.
With the launch of the Intel Rocket Lake-S architecture we will live a rather peculiar situation. According to the latest information, the chip giant Failed to complete transition to 10nm ++ process on time with its high-performance processors, which means you will have no choice but to resort to a 14nm adaptation of the Willow Cove cores, used in low-power Tiger Lake processors (10nm ++).
Intel Rocket Lake-S will keep the 14nm process, but unlike Comet Lake-S it will bring important changes thanks to the use of these Willow Cove cores, which will allow us to talk about a jump to the process of 14 nm +++. This should be Intel’s latest “tock” about this process, although after seeing the evolution we have experienced in recent years in this regard, it is impossible to take anything for granted.
Intel Rocket Lake-S performance in 3DMark is below expectations
The most important consequence of integrating Willow Cove cores into Intel Rocket Lake-S processors will be a notable increase in the CPI. There has been talk of an increase of up to 20% compared to the current generation, but as it is an adaptation of the 10 nm ++ process, the improvement may end up being smaller than expected.
The 14nm process will impose important limitations, to such an extent that Intel will have to limit the maximum number of cores and threads to 8 and 16, respectivelyThis represents a step backwards compared to the 10 cores and 20 threads of the Core i9 10900K. This movement would be offset by the increase in the CPI to which we referred, but the first performance test that we have had the opportunity to see is not rosy.
In the 3DMark database we have seen the results of a processor Intel Rocket Lake-S with 6 cores and 12 threads running at 3.5 GHz-4.2 GHz, normal and turbo mode, and this is below the Core i5 10400, which adds 6 cores and 12 threads at 2.9 GHz-4.3 GHz, normal and turbo mode. The first reaches 11,887 points in the physics test and the second reaches 12,828 points.
I want to think this is because the new chip is an early sample of engineering and the result is not illustrative of the final performance of the Rocket Lake-S series, but at the same time I can’t stop thinking about the problematic which could be that adaptation of the Willow Cove nuclei designed for the 10 nm ++ process to the 14 nm +++ process. In any case, let’s not rush, we will wait to see what Intel surprises us with, after all, the company has room for maneuver until the end of this year, when the launch of this new architecture will take place.
