crossfire Crossfire support

[RetroGamer9250]

Does the AMD Radeon HD 6450 LP 1gb support crossfire?

Specifically the Powercolor AX6450 is what I am wondering about.

Yes, but Crossfire itself is basically dead and even if you got 100% scaling the performance would still be worse than abysmal. We're talking about a "display adapter"-level GPU from 13 years ago.

Yes, though it’s probably not a great idea as two 6450’s isn’t going to do a whole lot. If you’re playing games which run well on an hd 6450, and they support and scale well with crossfire, and your board supports crossfireX, then yeah there’s worse ways to spend $10

 

But I’d still just look at an overall different GPU rather than crossfire for two low end display adapter cards.

why do you need crossfire?

The performance would essentially be the equivalent of a single 6450 +/- maybe 10% which you could say is within margin of error. Crossfire and SLI barely worked and even when it did, it was at most <50% performance gain. You were always much better off just buying a higher-tier GPU when these things were new.

I'm just doing it for fun since I have a couple laying around from a few old Dells

well then yeah, as long as the motherboard supports crossfireX, they should work

might have to fight with some different amd driver versions

yeah for fun I guess, but don't expect any miracles from crossfiring 2 very slow cards compared to today's tech

Yea it’ll be a good show off piece or something for two truths one lie.

I’ve been wanting to do this for a while

I take issue with this. Both Crossfire and SLI as terms are a bit complicated to the levels that were supported - namely the fact that you could use more than two cards with either technology. Games were more likely to properly support two-way SLI, versus three-way, or four-way, and it depended on the resolution that you were playing at, amongst other things, and the percentages gained would obviously be less and less as you continued to add more cards, even with perfect scaling.

 

So I disagree that they barely worked, but Crossfire had issues beyond performance gains. Even if you did gain performance, you had issues with frame pacing, along with runt frames, which caused stuttering issues that were present for years, even if your frame rate was high. The same issue presented itself on SLI, but it was more managed.
