Review: AMD Ryzen 9 7900 processor

More expensive than a 5800X3D with lesser 4K performance, that's progress right there.

 

I hope people buying a 7900 non-X and non X3D don't buy it for gaming indeed... but I doubt it. I have trust in those people actually buying it for workloads.

 

Not bad at mulitcore but gaming, get the 7600 instead.

 

I have a 3800x and x570 Asus Tuff built three yeras ago that will go to my wife that is need of a new pc.

Was looking at pricing of the new chipset platforms for a new mid-range gaming pc and ended up going with the 5800x3d and MSI x570s Tomahawk MAX. The 3800x pc has been a solid and great 1440p gaming pc and the pricing vs performnace gain for the new platforms didn't appear to be worth it for me.

No doubt the 7800x3d is likely going to be a great gaming cpu when released. But considering what is available now the 5800x3d was the route I chose.

 

Looking at these benchmarks, and with the knowledge that the X3D version is coming next month, I have to wonder what the point of the 7900X was.

 

It's not only the fact that it's more expensive than the 5800X3D that make it a poor choice for gaming, it" also the fact that AM5 boards are very expensive compared to the AM4 ones right now.
It's a much better option compared to the 7900x for productivity, unless you need something that heavily utilizes the CPU for extended time periods.
That 10% uplift could matter on such occasions. But then again, this one needs a lot less power under load. Yeah, the 7900x is a tough sell now.

 

Power consumption at idle seemed striking, then I remembered it had integrated graphics, though testing was done with an RTX 3090 installed, perhaps that's why it's power consumption in only that metric was greater than the R9 5900x, 78 watts vs. 69 watts? With multithreading use it was gobs more efficient. I have a 5900x, and I love it, but this is impressive. In another couple of generations I'd be tempted by such frugal and efficient power usage. https://www.guru3d.com/articles_pages/amd_ryzen_9_7900_processor_review,6.html

 

To me it's simple:
Does your workload benefit from higher clock speeds or more cache? If you have the ability to cool it properly, opt for the higher cache and overclock it for the best combo.

 

I was in the same boat, changed my 3800x for a 5800X3D, il buy a cheaper MOBO to use the 3800x in as i have spare RAM as weel.

 

Wait, didn't we just have Ryzen 7000 reviews recently? So this is AMD's strategy to spam with as many SKUs as possible to keep review buzz cycle going.

EDIT: oooh ones before had X

 

It's a normal strategy, first they release the best chips, and a bit later release the chips that have some small problems(that might explain the higher consumption at 1 core and at idle), to keep the news rolling

 

No way in hell Id buy a 6 core anymore. I just left a 5600x to a 5800x3d.

 

The point is that some guys need powerful CPUs for work instead of gaming, because not everyone buys good hardware for gaming.

 

I could afford a 7800 X3D and an AM5 set up but with having a 5800X3D i feel it's too early to let go of this system yet.

These chips might not be the best for gaming but there still better than most. If you're 100% into gaming then i'd still say go for AM4 and get the 5800X3D because this chip still has years of performance left, i have no doubt about that. I'd even go as far as 4 years from release so that would be whatever comes after 7XXX series. 8XXX series will be two years away and i'm sure still on AM5.

5800 X3D isn't cheap but the ram and motherboard can be had for very little money compared to AM5. You don't need an expensive mobo or ram to get the best out of a 5800X3D as long as the vrm is half decent you'll be fine.

 

12 cores & 24 threads 5.4GHz @ only 65w is pretty impressive...

 

Every day that purchase of a 5800X3D is looking better and better. These CPUs wouldn't seem so bad if it weren't for the atrocious motherboard prices. The cost of an AM5 system is just too much.

 

The 5800X3D as a "CPU" -gaming = very poor MT performance. I would still have the 7900 over the 5800X3D after a good ram kit and OC will finish it off nice. I only stayed on intel because I like lower latency and I play at 1080p and 1440p way more than 4k. But yes, if just gaming and you are on AM4 a 5800 would be no brainer I agree.

 

A decent solution for lower cost video encoding i spose, just a shame that any saving on your electricity bill are lost on the MOBO and RAM prices.

 

5800X3D is £350, the AM5 RAM kit and MOBO is how much if you want decent OCing. And that 65W is an AMD 65W, they have been making up the power draw on their CPUs for years.
