Rocket Lake Flaunts Up To 18% Higher Single-Core Performance Than Core i9-10900K

In the latest Rocket Lake teaser, Intel touted double-digit instruction per cycle (IPC) gains. If the recent UserBenchmark results (via Tum_Apisak) are accurate, we might be looking at improvements up to 21%.

Wielding Cypress Cove cores, Rocket Lake processors will once again top out at eight cores and 16 threads like in the pre-Comet Lake-S days. Therefore, the octa-core Rocket Lake processor from the UserBenchmark submission is likely the flagship chip. The processor reportedly features a 3.4 GHz base clock and 4.2 GHz boost clock. 

The Rocket Lake sample was running on MSI's Z590-A PRO-12VO (MS-7D10) motherboard. The last part of the model name (12VO) particularly caught our eye as it may be referring to Intel's ATX12VO specification, which aims to replace the chubby 24-pin power connector with a 10-pin one instead. ASRock has already squeezed the ATX12VO power connector into one of its Z490 motherboards so it looks like MSI did the same on its upcoming Z590-A Pro.

UserBenchmark doesn't have the best street cred in the benchmarking world so it's healthy to take the results with a pinch of salt. Rocket Lake is unreleased hardware so the software might not always behave correctly. Furthermore, it's just one Rocket Lake submission in compared to the average for tens of thousands of user benchmarks.

Intel Rocket Lake Benchmarks

2-Core368302292
4-Core682599566
8-Core1,1151,1561,042

Rocket Lake is expected to max out at eight cores so the Core i7-10700K is the logical comparison. For reference, the Core i7-10700K has a 3.8 GHz base clock and 5.1 GHz boost clock. The unidentified octa-core Rocket Lake processor delivered up to 21% higher single-core performance than the Core i7-10700K. However, the Rocket Lake was only up to 7% faster than the Core i7-10700K in terms of eight-core performance.

If we do a flagship to flagship comparison, the Rocket Lake is evidently at a two-core disadvantage with the Core i9-10900K. Regarding single-core performance, the Rocket Lake outperformed the Core i9-10900K by 18%. It should not be forgotten that the Core i9-10900K has a 3.7 GHz base clock and 5.3 GHz boost clock. For once, it appears that Intel is actually offering substantial IPC improvements instead of just jacking up the clock speeds. Despite having two less cores, the Core i9-10900K was reportedly only 4% faster than the Rocket Lake sample.

Intel will launch Rocket Lake first quarter of 2021. An alleged, leaked Intel roadmap reduces the timeframe to late March so it might be a while before we corroborate Intel's claims or UserBenchmark's numbers. However, the real question is whether Rocket Lake can handle Ryzen 5000, which promises up to a 19% increase in IPC.

    Its kind of funny. +17% or +21% might be a really great thing ... except if you are actually CPU bound, in which case, assuming some reasonable scaling, then you're only 15% to 19% less impacted by being CPU bound.

    I would rather think that for a given system -- if upgrading -- that leaving a competent late-generation CPU in place and doubling or quadrupling the memory, the SSD and possibly the GPU card ... would yield better results. For maybe similar money.

    $ / improvement... that's the gig.

    Core i9-10700K = 5.1 Ghz = 148 =>> 1 Ghz = 148 / 5.1= 29.02
    Rocket Lake = 4.2 Ghz = 179 =>> 1 Ghz = 179 / 4.2= 42.62

    1 Ghz Rocket Lake vs 1 Ghz 10700K = 42.62 / 29.02 = 147% = +47% IPC ?¿?¿??¿? I don't think so.

    FAKE!!

    I would rather think that most people aren't bothering to upgrade at all for 20% gains and skip a few generations instead - in the 90s where CPUs were getting much faster much quicker, most people upgraded only every 3-4 years, usually to something that was both more than twice as fast and cheaper.

    Enthusiasts' willingness to throw absurd amounts of money at tiny incremental upgrades is nuts.

    So, they're announcing they plan to show up months late and cores short, but hey, they'll at least be hanging in there on IPC. What, do they want a participation prize?

    Right now it's best to upgrade your gpu (if you can find one...) rather than upgrade other parts of your system. Unless you have a 6 year old pc to start with.

    It keeps the hopes of intel fan boys alive. It remains yet to be seen if Rocket lake will be faster than Zen 3. And they won't have an answer for the 12 and 16 core Zen 3 parts.

    I saw real Tiger Lake vs Renoir Benchmarks and I'm not impressed by these fake scores.

    AlderLake is Intel's real last chance.

    comet lake winner + 20 lanes pcie4 + avx512 + dlboost + xe gpu + 18% ipc core update + DDR4 memory speed updates.

    Those updates should result in performance updates in a wide range of applications. Just add one of the new pcie4 m.2 SSD drives, a pcie4 graphics card and some high speed memory.

    The DDR4 memory speed update you are talking about is intel going from DDR4 2933 to 3200. So don't expect much there the rest of the improvements should be nice.

    Uhh 5600x is faster than 10900k in single core not even overclocked. now that is the slowest of the new 5000 series. so 5950x is even faster. but wait. by the time this crap 8 core 14nm++++++++++++++++++ comes to the market Ryzen 6000 series will be out but I am willing to bet AMD will release an XT variant in about 6 to 7 months from when their yields are better for the 5600xt 5800xt and 5900xt pushing them all to or close to 4.9ghz single core boost speeds. Intel at this point is irrelevant in all aspects they are only going to have an 8 core CPU in 2021 if they are lucky, while AMD is still at 16 core that is in fact faster and will get faster from firmware and driver updates and software optimizations for the new Zen 3 cores. I have a 3800x that already boosts itself to 4.65ghz in Ryzen master before better to best yields of the XT. AMD is faster uses less power and has more cores and more threads. so it is possible a 5950x could boost past 4.9ghz hitting that make believe magical number of 5ghz in one or two cores leaks already indicate this happening but lets just wait and see after November 5th. Now if Intel does come out with something better GOOD it will make AMD step up even more cuz Dr. Lisa Su loves to compete PERIOD..
