Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTGaming Performance: 720p And Lower
The reason we test games in CPU reviews at lower resolutions such as 720p and below is simple; titles are more likely to be CPU bound than they are GPU bound at lower resolutions. This means there are more frames for the processor to process as opposed to the graphics card doing the majority of the heavy lifting.
There are some variances where some games will still use graphical power, but not as much CPU grunt at these smaller resolutions, and this is where we can show where CPU limitations lie in terms of gaming.
We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K, the Ryzen 9 7950X, and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Civilization VI
World of Tanks
Borderlands 3
Grand Theft Auto V
Red Dead Redemption 2
F1 2022
Hitman 3
Total War: Warhammer 3
Cyberpunk 2077
Digesting our results at 720p (and lower) resolutions, we can see that things are quite competitive at the top end, especially with the Core i9-13900K and the Core i9-12900KS across most of the games. Some of the games from our testing look to benefit from a different variable, whether that is core count, quality of cores versus core count and frequency; L3 cache size, or a mixture of all three.
In World of Tanks, the majority of the field of processors on test look to be within a certain margin depending on frequency, IPC, and core count. The Ryzen 9 7950X does well here, although the latest Raptor Lake chips seem to be hovering around the levels of performance as the previous 12th Gen Core chips. In Civ VI, the latest AMD Ryzen 7000 and their Zen 4 cores dominate the field, while the 5800X3D and R9 5950X are also competitive. Behind these come the Intel chips with the Core i9-13900K performing the best of those.
Overall, it's a bit of a mixed bag at 720/480p in terms of performance. There are cases where Raptor Lake performs well, but equally, the same can be said for the Ryzen 7000 chips. But ultimately, none of the top chips here have a 95th percentile frame rate lower than 170fps in any action game, while the more unique Civlization 6 never drops 114fps. Which is to say that these high-end CPUs aren't likely to be a gaming performance bottleneck any time soon – getting a GPU that can keep up at higher resolutions is going to be the harder task.

PCs are idle (or used for light browsing, reading bews, watching youtube or a movie, etc.) most of the time. Intel idles at around 12W due to E cores while AMD idles at around 45W which will make the energy consumption 4x. Replyt.s - Thursday, October 20, 2022 - link
idle around 45w? sources? My 5600G idle at 11W. others, around 7 s/d 17W. Replytitaniumrock - Thursday, October 20, 2022 - link

And where it states the AMD vs Intel watt vs watt? ReplyWrs - Friday, October 21, 2022 - link
A 5600g is a monolithic chip, just like the Intels. A 7600x or 7950x is a multi-chip module, though, with 2 or 3 modules, and the IOD idle is very substantial now with all the PCIe5 lanes. Bottom line Zen 4 is more efficient when doing major work, courtesy of being one process generation ahead, but Raptor Lake and Alder Lake idle lower. If you want low idle with Zen4, wait for the SoC variants like your 5600g. Replytygrus - Saturday, October 22, 2022 - link
They don't run constantly with at maximum power consumption in all workloads. They use less while gaming or more integer & less FP/AVX. Highest usage probably when they have a performance lead over the other. AMD can run at lower power limits & loose a few % in many cases. Replyneblogai - Thursday, October 20, 2022 - link
I was hoping for Ryzen 7000X iGPU benchmarks too. There are no proper comparisons of them vs Intel's 32EU iGPUs on the internet. Replynandnandnand - Thursday, October 20, 2022 - link

It's similar to the UHD 770 in Alder Lake, sometimes a little better or worse. About half the performance of a 5700G which is impressive for 2 CUs.
UHD 770 in Raptor Lake gets +100 MHz across the board, so that could make a slight difference. Reply

Thanks. I liked the ones on Techpowerup, as they include tests at 720p low, and tested more than a few titles. Part of my interest is the need to compare to Tomshardware 7950 iGPU results, which looked suspiciously low for the specs, and probably faulty: https://www.tomshardware.com/news/ryzen-7000-integ...

About power consumption.I think it is completely useless to measure it when running a useless benchmark that you then don't even use to compare the relative performances to other CPUs.
It would be much worth having a measurement for some more useful (common?) benches, just to understand when a real work is applied how much the CPU is consuming and, related to the performances, understand how efficient it is.
Just think what the results would be if the CPU would be artificially limited (by BIOS/driver) in Prime95 bench: you would measure a much lower consumption that extrapolated for other tests, and you could just think the CPU is consuming a fraction of what is does. It's the same for the torture benches of GPUs. The max consumption in that test is useless to understand how much they really consume while gaming, and in fact, most of them are artificially limited or just hit the max TDP (which is again not a measure of power consumption).
If you don't want to provide the power consumption for most benches, at least use a bench that gives a comparable performance, so that (at least for that test) one can make a comparison of the efficiency. Reply
