There is been a flurry of leaks around Intel’s future Rocket Lake desktop CPUs, and it points in reverse instructions as significantly as what to anticipate from the CPU.

Most lately, there are some SiSoft Sandra outcomes by using THG that demonstrate an 8C/16T Rocket Lake chip running under the functionality of a Ryzen three 3300X with a claimed one.8GHz base clock and a 4.4GHz boost clock. Last week, info from Ashes of the Singularity and Geekbench implied that the new CPU was an approximate match for the Ryzen 7 5800X. Both equally just can’t be true, but the greater, greater figures are more probable to be precise. The a lot more new outcomes may mirror an early CPU, reduce-than-claimed clocks, a minimal-watt TDP aspect, or some other attribute that would impact the relative comparison.

Rocket Lake utilizes Intel’s Cypress Cove architecture on a 14nm approach. Cypress Cove is fundamentally Intel’s Sunny Cove (Ice Lake) CPU main, backported to 14nm. Sunny Cove, if you recall, was a authentic IPC uplift for Intel, but it traded again virtually as much frequency as it gained in IPC. As a end result, CPU general performance in numerous purposes was flat on a main-for-main or clock-for-clock foundation.

The issues that pressured lower clocks on Intel’s 10nm node with Ice Lake, nonetheless, never exist on the older 14nm node — and that, in convert, indicates that Intel really should be equipped to supply a internet CPU functionality enhancement with this shift. At the identical time, increased IPC normally involves far more power use at a supplied frequency, and Intel cut the whole number of CPU cores on this chip to 8, down from 10. We really should also expect to see indicators of larger for each-main ability consumption.

GeekBench-Leaks

This image, from WCCFTech, summarizes some GeekBench 5 functionality final results from last week. As opposed to the Sandra final results, this knowledge seems to be exactly like what we’d forecast.

The Main i9-10900K is 17 p.c slower in single-core testing, implying that Rocket Lake retains all of Comet Lake’s clock at 14nm and completely positive aspects from its IPC uplift. On paper, the Core i9-10900K’s 10 cores should really be 25 p.c more quickly than the unnamed RKL CPU’s 8, but in exercise, it’s only about 1.12x faster. As we theorized, bigger IPC from the RKL CPU helps to compensate for the lessened selection of cores.

The Main i7-10700K’s relative overall performance is also exciting, specifically if you contemplate them compared with, say, AMD’s advancements from the 3950X to the 5950X. In AMD’s scenario, the 5950X gains additional effectiveness versus the 3950X in 1T manner than it does at full load, partly due to the fact each CPUs bump up from the energy limitations baked into all AM4 motherboards. The reality that the RKL CPU can conquer the Main i7-10700K by 22 % in 1T but only by 9 p.c in multi-threading implies that the clock gap involving the two cores is larger in one manner than the other.

These effects also match with what we know about Intel’s product options and strategies these past handful of several years. The organization has been emphasizing solitary-threaded burst functionality and quick-period workloads, and leaning on types like gaming, which it nevertheless received more usually than it dropped till the start of AMD’s Ryzen 5000 collection a couple of months in the past.

Incidentally, this knowledge also implies rough parity among RKL and the Ryzen 5000 sequence on a core for core basis. AMD’s desktop system would nevertheless offer you extra total cores than Intel, making it possible for for bigger optimum general performance in a solitary socket, but early knowledge implies Intel will still be in a significantly greater position when the new chips debut at the stop of March. With core-per-main parity, Intel could even consider an in general price/performance management posture in sure match-ups, really should it opt for to selling price to do so.

As often, just take all rumors, leaks, and equivalencies with a grain of salt.
