6700XT vs 7800XT (First Build) (self.buildapc)

Hello, very simple question. I am doing my first build and about to order my parts, but I was wondering if the 7800XT is worth the leap and possible long-term gains over the 6700XT? I wanted to know personal experience from normal people, rather than a bunch of tech youtubers. Also if you use Linux, that would be quite helpful.

You can expect about a 20% better performance. You also have 4GB more of RAM which supposedly is good for future-proofing but only a few games and applications can even use more than 12GB right now. I don't expect it to be the norm anytime soon.

On the Linux side you should check to see if people on RX7000-series have resolved any initial issues with graphics drivers, since I've often heard reports of problems when AMD graphics cards are fresh out of release.

It's not just about how much RAM, it's about how big the memory bus is. The 6700XT has a 192-bit memory bus, and the 7800XT has a 256-bit memory bus. That means the RAM can work faster.

Probably why the 6700XT is matched by the 3060ti instead of the 3070; even though the 6700XT has 4GB more RAM, the 3060ti has a 256-bit memory bus.

Thanks for the more in-depth comment. I want to build something that'll last a while without me having to upgrade it. Doing a minimal gaming build with the Fractal Terra.

What resolution does your monitor have or will have?

The 7800xt is almost certainly going to be better in every way, but how limited is your budget now? If you're planning on 1080p for the forseeable future the 6700xt is damn good, its even pretty good at 1440p, its a GREAT card for the price point. A graphics card swap down the track (money aside) is a very easy swap, so have a think about would you rather "future proof" your mobo/cpu/ram with the price difference or get the better card now.

I only have 1080p atm, but was planning on upgrading my monitor. I'm still debating on what to do really. My mobo is already future proof, and I have 32 gigs of RAM. I saw an open box 6700 XT going around 250, so tbh I might just wait for the gen after this one or something before I upgrade the monitor and get a new GPU. Only issue is that I want to go SFF, so I wonder if the next gen would even fit in this thing. The Terra can fit up to 320 mm, but it still scares me.

Minor ramble aside, thanks for the advice. This actually helped me the most.

Edit: Yeah these things are going for like 200 on the secondhand market. Ez pick.

Happy to help, I scored my 6700xt second hand for about $225US about 12 months ago. It was an absolute steal, not the card I was looking for but at that price I was willing to give it a go and I havent had a single complaint yet at 1080p.

7>6

[–] shinnoodles 3 points 9 months ago (1 children)

Damn, is it really that simple? Alright.

[–] [email protected] 1 points 9 months ago

Be careful though, because 7 ate 9

The only issue with the 7800XT is that the 7000 series is still kind of unstable on Linux

[–] brenticus 2 points 9 months ago (1 children)

Is it? I haven't seen any problems since I put together my 7800XT build in November.

Well, other than having a cable jammed against the top of my case too tight so if my cat jumps on it the graphics card loses power and the driver crashes... but I assume that's not what we're talking about.

[–] [email protected] 1 points 9 months ago

It depends on your distro I guess

[–] sploosh 2 points 9 months ago

6.3+ kernel runs the 7800XT just fine.

[–] LinusOnLemmyWld 1 points 9 months ago

malarkey, as a general comment. depends on distro and Wayland vs x11. modern distro with Wayland no issues, typically
