I need your help to choose my next CPU Contenders :
Ryzen 7700x Single CCD 8/16T with 8+32Mb Cache, 4.5>5.4Gh @ 230£
Ryzen 7800x3d Single CCD 8/16T with 8+96Mb V-Cache, 4.2>5Gh @ 310£
Ryzen 7900x Dual CCD , 2x6/12(12/24) with 12+64 Cache , 4.7>5.6 @ 310£
After researching for some time I am not any wiser
My uses for PC is Gaming some software Compiling and virtualization like QubeOS.
CPU will be installed in ASUS TUF Gaming B650-Plus with
Lexar ARES DDR5 RAM 32GB Kit (16GB x 2) 6400 MHz CL32 and RX 6950XT OS only Linux
Things I am struggling with the choice are :
Single 8/12 vs Dual 6/12 CCD for gaming.
64Mb Cache on 7900x its not small amount even compeering to x3d and have higher clocks and more cores.
7700x have highest clocks and due to single CCD most thermal head room for gaming, 8 cores might be fine for rest?
Online revives are inconsistent for 7800x3d some showing no performance gain for 4K gaming.
For virtualization and compiling more cores is better.
The X3D chips give a good boost but when you have a 6950 XT it feels kinda silly not going for the 7900X for your specific use case. Already 8 cores are becoming a minimum requirement for high+ graphics.
So my advice is, X3D can be a good boost in some titles but in your case I would get the 7900X for the better productivity boost.
However, I would also step up to the Asus Gaming X670E Plus, reason being you can then upgrade to a 2026 12 core Zen 6 almost guaranteed, without skipping a beat. It is a 90% likelihood it will happen. That means you will not need a new platform for the coming 5 years. No need for a new case, Mobo or PSU. Factor in 128 GB RAM for… $200? Plus an 8TB SSD in 2026 when it costs $200, plus CPU $500 plus $800 GPU, means something like $2500 including whatever you buy now. For 7 years, that is like $350 per year. Not bad considering you will game on high+ all that time
Considering your uses (gaming, software compiling, and virtualization on QubeOS), here’s my take:
If gaming is your primary concern, the 7700x seems like a solid choice with its high clocks and potential thermal advantages.
If you’re heavily into software compiling and virtualization, the 7900x might be worth the investment for its dual CCD, more cores, and cache.
It ultimately depends on your priorities. I’d lean towards the 7700x for a gaming-centric build, but if you want an all-around powerhouse, the 7900x might be your go-to.
Good luck with your decision!
What games do you play? for esports games or default triple a titles it doesn’t matter much. But if you like playing strategy, simulation or VR games, then i would pick the 7800x3d.
You do have to decide what the main use case is for your computer. Do you mind getting less fps in a game more or less than a simulation taking 20% longer?
I’d say get the 7800X3D now if it meets your current needs, then upgrade at some point in the future. I can see AMD doing a dual chiplet CPU that combines an X3D die with a Zen4C efficiency die at some point.
Only get 7800x3D when you max out GPU first, such as RTX 4090. Put same dollar towards GPU give you most FPS.
If you do a lot encoding or compiling, 7900x/7950x may be also feasible.
If primary is gaming, I would avoid dual CCD unless 7950X3D. You need to also state what games you are playing. If just single player, it doesn’t matter. Sims=X3D. Competitive multiplayer? Intel is still a valid choice because of the 1% and 0.1% lows.
