I’m planning on building a new rig within the next six months to a year and I can’t decide on weather or not to go with a 7000 or 9000 cpu because I’ve heard a lot of reviewers say there isn’t a big difference between the two ?

I stopped being crazy about computers in 2021, because i finally got a pc and never had the money to upgrade. But now im ready to upgrade, and have two likely options for a cpu: 7700x and 9900x. the difference in price is 350 to 440 pre tax (usd) which seems way too good to be true, since thats around a 20% difference for a 50% core/thread increase. thats why im skeptical about my options. i mostly play fps games and a bit of other games on the side like black myth wukong, and im getting into cyberpunk later. ill be pairing it with either a 4070 super or 7900 xtx.

When building a new AM5 PC, would you go with 9000 series or 7000 series?

Do you think the performance benefit of 9000 is worth the additional costs?

And what are your thoughts when comparing 9700x to 7900x ? which are about the same price (at least in my country)

Thank 🫵 !

So I built my PC about 7-8 years ago, and have upgraded parts since. I currently have a MAG B550 Tomahawk (Just purchased), 6700XT Gpu (fairly new), 16gb ram, and a Ryzen 7 5800X with Arctic Liquid Freezer AIO cooling.

As soon as I upgraded to the 5800X It started overheating (after reapplying enough paste and redoing it a few times) so I thought I would upgrade to an AIO liquid cooler setup. The change was almost unnoticeable, maybe a few degrees smaller, but still super high. I made sure there were no overclock settings checked in the bios. After a bit of research I found lots of people have the same problem. I rode with it till my motherboard fried from slightly pushing her limits. (I had a funky matlab code running while hulu and a few other things may have been open). I want to be safe, plus I dont feel like gaming at 80-90+c is ok in the long run.

TLDR; trying to decide which cpu to upgrade, along with a 6700xt are the differences going worth the price difference?:

Ryzen 7 9700X is 312, 7800X3D is $429

Ryzen 9: 7900X is $360, 9900X is $380, 7950X is $480 ( slightly out of price range, honorable mention)

I'll keep it short since the video explains it well. Except for specific cases, the average improvement between equivalent Zen4 and Zen5 (7600X vs 9600X), after a year since Zen5 came out, went from 5% to 6%.

I'm not saying never buy a Ryzen 9000 series, but if a 7000 is cheaper for you, that extra money can go to the GPU, memory, storage, or a cooler case if you feel like it.

If the price difference is nothing, go for the 9000, in the future we should start having programs that take good advantage of AVX-512 or AVX-10.1 (it's the same but properly standardized), and the performance in professional tasks is much better than in games.

The bottleneck of the current AM5s is the input/output circuit, the IO die, since it has a pretty mediocre memory controller (hence the 6000 MHz memory limit for Ryzen while Intel is laughing its ass off with 8000 or more), and it also limits bandwidth in connectivity. Apparently they'll fix it with Zen6 next year.
