The AMD Ryzen 9 7900, Ryzen 7 7700, and Ryzen 5 7600 Review: Zen 4 Efficiency at 65 Watts
by Gavin Bonshor on January 9, 2023 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 Ryzen 7000 series 65 W SKUs, as well as the other Ryzen 7000 processors tested, 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
We saw relatively decent performance across the board at very low resolutions of 720p and below, with low to minimal settings selected to bring raw CPU performance into play as opposed to discrete graphics. In most titles, the 65 W Ryzen 7000 CPUs trade blows well compared to other SKUs from both AMD and Intel, despite their power limitations.
The biggest limitation of power came in our Total War Warhammer 3 benchmark, where limited power did seem to handicap performance at 720p more than we've seen in other games so far.

"Looking at the Ryzen 9 7900, it marginally beats out the Ryzen 9 _7950X_ and sits" - Typo, should be 5950X, above borderlands 3 test on conclusion page.Gavin Bonshor - Monday, January 9, 2023 - link
Thank you for spotting that!MadAd - Monday, January 9, 2023 - link
Did I miss the single core performance test?djsvetljo - Monday, January 9, 2023 - link
I am concerned about Zen4 minimum power draw (idle). Judging by graphs on page 2, it seems like CPU consumes 20 watt on idle???Going back to the Zen4 X comparison vs 13th gen, Intel seems to have advantage at idle. Planning to update home server that sits on idle or very low load 80% of the day, but needs to be on 24/7. I eventually am planing to run VMs on it (rare gaming with GPU pass thru). Thoughts?

thoughts? you are creating a wacko system. one site you want to have low low idle, and than intel is better although the latest generation is less difference... its not the cpu, its the total package with pci-e5 etc that is upping the idle power. on the other side you want GPU power which eats already 50% of your total idle power. so the diff between intel and amd will now be only way less vs total idle.. on top for VM you should have an AMD multicore for sure. my advise? wait for the 7000 APU it might fit both your needs.kpb321 - Monday, January 9, 2023 - link
Is it just me or do the 7600x and 7700x just seem like bad deals compared to the newly released chips. $30 moves you up to the 7700 or 7900 respectively with the same rated boost clocks for ST task. Lower base clocks will hurt but the additional cores will help compensate in most MT situations. The 7700 beats the 7600x in many of the multi-threaded tests and does it for a small premium and while using a lot less power in the process.steveofwa - Monday, January 9, 2023 - link
Seems like there is no reason for the "x" versions to exist. They can have their non X with good power efficiency, and the x3d for performance.Byte - Tuesday, January 10, 2023 - link
X is now the "founders" edition where rather than get discounts like kickstarter, you pay for the privilege for getting it first. Nvidia did this with the 2080Ti FE being $1200 whereas msrp was $999. They saw it work well so everyone taking a page. Ryzen traditionally launched with non-X and that was the go to. The X is mostly for emotional reasons which plays a bigger factor in marketing than you think. Most people will never lower themselves to a x700 series card for instance. That is why nvidia did two 4080s in the beginning but backtracked. Wrong move.AndrewJacksonZA - Monday, January 9, 2023 - link
Hi. For "(3-3) Dolphin 5.0 Render Test" you have the test results in your Bench different to the test results in the graph.In the graph:
Intel Core i9-12900KS = 182.2
In your Bench:
Intel Core i9-12900KS with DDR5 = 169
Intel Core i9-12900K with DDR4 = 181
Also, according to your Bench, for "(3-4c) Factorio v1.1.26 Test, 20K Hybrid," the i3-12300 with a score of 72 beats *ALL* the new Ryzen 7xxx CPUs. Can you confirm that please?
I haven't checked any of the other results to your bench but suspect that more might also be different. Also, are efforts underway to update the Bench to include these results, please?
Thank you
