Intel Core i9-14900K, Core i7-14700K and Core i5-14600K Review: Raptor Lake Refreshed
by Gavin Bonshor on October 17, 2023 9:00 AM ESTSPEC2017 Multi-Threaded Results
Single-threaded performance is only one element in regard to performance on a multi-core processor, and it's time to look at multi-threaded performance in SPEC2017. Although things in the single-threaded SPEC2017 testing showed that both Zen 4 and Raptor Lake were consistently at loggerheads, let's look at data in the Rate-N multi-threaded section.
Looking at multi-threaded performance in SPECint2017, the only test that seemed to benefit from the increased core clock speeds of the Core i9-14900K was in 502.gcc_r, which is a simulation based on the GNU C compiler that analyzes source code inputs and compiles a few large files instead of many different small files. In this instance, we saw 34% more performance with the Core i9-14900K than the Core i9-13900K, but we are currently re-testing to ensure this isn't an anomaly and is an accurate representation.
Of course, it's also fair to assume that the clock speed increase yields a benefit, although we aren't seeing this translate to more performance in other tests within the SPECint2017 MT suite.
The last section of our SPEC2017 testing is the SPECfp2017 MT, and once again, we are seeing some gains, but they are very marginal at most. We did actually see some regression in one test, 511.povray_r, which represents a 2560 x 2048 pixel rendering of a chess board and is saved as a Targa (.tga) file extension. Given that we also run a specific Persistence of Ray tracing (POVRay) test in our suite, and we didn't see this regression here, it could be an anomaly, and as we've stated, we are re-testing SPEC to eliminate any of these anomalies or variations.
Overall, in both ST and MT SPEC2017 suite performance, the Intel Core i9-14900K doesn't represent significant gains in performance over the Core i9-13900K.

Maybe they do it through a proxy app, part of the overall package of Windows' Telemetry?pookguy88 - Tuesday, October 17, 2023 - link
you didn't have a 13700k to test against?shabby - Tuesday, October 17, 2023 - link
Yup pity, that would show us what those 4 e-cores can actually do.TheinsanegamerN - Tuesday, October 17, 2023 - link
I mean they still dont have a GPU test bed going on 3 years post fire. I wouldnt expect much.nandnandnand - Wednesday, October 18, 2023 - link
I recommend everyone go to Tom's Hardware if they are missing something here. They'll have the reviews, decent ones IMO, and are owned by the same company as AnandKek.TheinsanegamerN - Thursday, October 19, 2023 - link
Tom's Hardware was caught shilling for Nvidia eons ago. They're another dinosaur of the tech space.Techspot, Techpowerup, and reviewers like gamers nexus are the new hotness.

Some motherboards will let you just set a power limit. I'd like to see a benchmark where the power limit is set to only the advertising number (125 W) and see what it can do with that constraint. 400+ watts just seems insane. My laptop is currently suffering terrible battery life because the CPU throttles up and gets hot and cooks the laptop because of exactly this Power Be Damned philosophy. I want a quiet desktop that isn't going to cook me if I'm sitting next to it, and isn't going to just cook the motherboard components and fail after a few years.I was expecting the new chip to be slightly more power efficient with a year of design tweaks and improvements. (And you'll note Intel wants you to think this because they kept the 125W marketing power usage on the box.) I am kinda baffled how Intel is executing so poorly. Nobody had a gun to their head forcing them to release this product. There's some deeply broken structural inertia in the organization to just keep pumping out products and not disrupting the flow of new model numbers. Somebody in Intel should have been screaming and said the plan wasn't working, rather than just keeping their head down to deliver a new model number for no reason.

If you want low power, get a ryzen. The 7800x3d tops out at just 50 watt.Performance loss, if anything like raptor lake (which this is) will be 15%+ down at 125 watt, more if they make heavy use of P cores.

Andandtech did this with the 13900k vs 7950X at different TDP/PPT. Basically the Ryzen at 65W TDP or 88W PPT was faster than Intel at 125W TDP. Once the Ryzen was set to 105W TDP or 142W PPT the Intel needed 253W TDP to be faster. In fact the scaling on the Ryzem dropped off quite quickly over 105W TDP.mode_13h - Wednesday, October 18, 2023 - link
