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.
