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.

This power consumption / heat output is insane… this is putting their 90nm Netburst Prescott / Pentium D Smithfield days to shame. Remember when Apple left IBM/Motorola alliance? Power architecture power consumption going thru the roof, and intel JUST pivoted back to PIII/Pentium M-based Core arch. No wonder why Apple dumped Intel, they called what they were seeing really early on. Arm for windows/linux desktop needs to get more serious, apple's desktop arm is proving nearly as powerful using a fraction of the power draw. Windows is ready, and can even run non-arm code too.herozeros - Tuesday, October 17, 2023 - link

What point are you trying to make, that you have no clue how thermodynamics work?This 14900K manages to pull 430 watt peak. 430. 0.43 kilowatt. one CPU.
It is still beat by a 80 watt peak 7800x3d. What is your point?

I think the point was that you don't have to abandon x86 for ARM to achieve good efficiency, just Intel.The Von Matrices - Thursday, October 19, 2023 - link
People remember Netburst CPUs as being absurdly power hungry, but they forget that even the most power-hungry Netburst CPUs still only had a TDP of 130W. Today that would be considered a normal or even a low TDP for a flagship CPU. It's actually understating the TDP if you compare it to a Netburst CPU.GeoffreyA - Friday, October 20, 2023 - link
And didn't Cedar Mill further drop that to a 65W TDP?GeoffreyA - Friday, October 20, 2023 - link
Possibly, ISA is just a small piece of the power puzzle, and the rest of the design is what's carrying the weight.An interesting article:

Did i miss something or are there no temperatures shown? Because 428W shouldn't be on the low side and demands a good Cooling Solution.Gastec - Tuesday, October 17, 2023 - link
Just one question: do these AI "tools" connect to the Internet, after they "measure specific system characteristics, including telemetry from integrated sensors", to send that data to those Intel servers that are in the "cloud"?TheinsanegamerN - Tuesday, October 17, 2023 - link
Of course they do. Even if they say they dont.
