Hi everyone,

Previously, I posted some cpu and gaming benchmarks between the 11900k and 12900KF using ASRock motherboards here. I would like to do the same but this time comparing the intel i9 12900 KF vs. intel i9 13900 K vs. Ryzen 9 7950X using the ASRock Z690 Aqua OC and ASRock X670E Taichi.

I’ve selected five benchmarks for this review which includes three games I currently play and two benchmarks I use for stability testing. Peak power measurements at the wall using a Watt-O-Meter are also reported.

The systems consist of the following:

-System 1: ASRock Z690 Aqua OC and Intel i9 12900KF (Engineering samples)
-System 2: ASRock Z690 Aqua OC and Intel i9 13900K (Engineering samples)
-System 3: ASRock X670E Taichi and Ryzen 9 7950X (Engineering samples)

-RTX 4090 TUF OC
-2 x 32GB 5600cl40 DDR5
-Noctua NH-D15 Air cooler
-1200W Gold rated PSU
-1TB M.2 drive
-1440p @ 165Hz - 27inch G-sync monitor
-MX4 thermal paste

The results shown below are divided into three categories:

1) System at stock settings with memory set to XMP profile (5600 MHz - cl40)
2) CPU manual OC with memory set to XMP
3) CPU manual OC with memory manual OC

Manual cpu overclocks:

-12900KF P-cores = 5.1 GHz @ 1.25v, E-cores = 4.1 GHz and uncore = 4.3 GHz.
-13900K P-cores = 5.5 GHz @ 1.22v, E-cores = 4.4 GHz and uncore = 4.6 GHz.
-7950X core = 5.25 GHz @ 1.20v

Manual memory overclocks:

-12900KF 6,000 MHz - cl30-38-38 @ 1.43v
-13900K 6,000 MHz - cl 30-38-38 @ 1,43v
-7950X 6,200 MHz - cl32-38-38 @ 1,43v using AMD’s aggressive timing profile

Some additional notes: I left memory integrity enabled in all tests as this feature is now included in the latest win 11 versions. GTAV framerate would have been higher but forgot to disable v-sync in all tests so capped at 165 FPS.

In summary:

the 13900k provided a nice boost in performance over the 12900kf. In cinebench there was a 38% increase and in gaming 19% on average when comparing both systems at stock settings with XMP profiles enabled. Overclocking the 13900k provided an 8% boost over stock settings in cinebench however had minimal impact on gaming performance (less than 1%). Overclocking the memory helped further increase gaming performance by 3%. The performance boost of the 13900k over the 12900kf did come at a power consumption cost. In cinebench at stock settings the 13900k consumed 38% more power than the 12900kf at stock while for gaming, roughly 14% more power. Overclocking the 13900k in combination of down-volting helped reduce the power consumption by around 10%

The 7950X cinebench benchmark also has a nice boost in score over the 12900kf with an 40% increase in performance and 5% less power consumption at stock settings. Gaming performance increased by 23% in World of warcraft but decreased in the other two games when compared to the 12900kf. Overclocking the 7950X added an additional 2% performance gain in gaming while lowering the power consumption another 8%. Overall, the 7950X has similar gaming performance to the 12900kf but at 90% of the power consumption when both these cpus are overclocked.

I've also included comparison for 3DMark Port Royal to see if any small improvements to the GPU score could be gained and although the difference is very small, the 13900K pulled ahead when overclocked in combination of a memory overclock by almost 200 extra points when compared to the 12900k and about 100 points above the 7950X.

Future testing will include disabling e-cores for the 13900k and disabling 8 of the 16 cores (CCD2) to see how it impact gaming performance and results will be updated in this post.

I hope these results are helpful and open to suggestions if anyone would love to see certain benchmark comparisons in the future.

I would have preferred to see graphs that aren't visually misleading. The gaps are 10-15 fps difference, scores are MAYBE 10% in favor of Intel with the synthetic scores being within margin of error (<5% vs AMD). This kind of thing is seen as sleazy by anyone that knows how to market one product over another. Bottom of the graphs should read "0" for framerates and scores. This legitimately makes Intel seem insanely better compared to AMD, which it isn't by any metric that you'd notice on any level.

AMD's only serious loss vs Intel is their platform cost for AM5. It's so much of a problem that unless they drop motherboard prices by a solid 20% across the board, they are likely going to lose the momentum they built on up to this point.

Definitely don't want to end the post on a bad note. Love the comprehensive testing done by people on OCN, but don't do graphs like that. It looks like the same kind of marketing BS we see everywhere. No need to exacerbate the win unless you want people like me to nitpick your work. :p

I'm always trying to figure this one out. If a GPU is undervolted and at the maximum temp before it drops core clock speed, then a newer/faster CPU could give it more FPS and it would just drop the core clock anyway?

13900K is a BEAST for sure! Imagine using DDR5 7200-8000!
I'd consider 13900K to be the current champ for an all gaming build, no contest. And it accomplishes this with 8 performance cores vs the 7950X's 16 full speed performance cores. Makes me excited to see what intel's new raptor lake-s lineup performs like once they drop.

Definitely! Plus they are cheap considering what you’re actually getting. I remember how expensive (10/20) Intel 10900K’s were, sold out everywhere $1,000 bucks a pop for even a standard chip on eBay, blazing fast in games, but they would get whooped in multithreaded by the cheaper Ryzen chips. And now the 13900K is less expensive and more powerful as well. Crazy how pure competitiveness changes everything.

**** ....

Arctic 420 AIO dispatched, and my refund for the 360 was processed yesterday.

And the case is in stock at both Scan and OCUK, but my order with OCUK didn't dispatch yet, I sent a webnote as it was 2 hours past their phonelines closing, hopefully it will dispatch tomorrow or monday at the latest.

Z790 SOON!!!!

That’s awesome. Are you getting a 13900KS?

Yes when it comes out, going to spend a while testing for any ram OC differences between the boards with the current 12600k.

All the CPUs are engineering samples. How valid are the benchmarks vs actual commercial units?

My scores and framerate seems in line with what others have posted on hwbot and on a few forums on OCN. Same as max overclocks on air cooling, so I wouldnt say there is a big difference between ES and retail samples in this thread.
