Any news on 7800 xt?

random_matt · 20 Jul 2023 at 11:58

NVIDIA: Anything below the RTX 4090 sucks.
AMD: Anything below the 7900 XTX sucks.

Is that about right?

Kinda shocking how quickly the 3070(i've owned one) went from a proclaimed 1440p RT card to 1080p with reduced settings

Lol. TBF it performs pretty well in 1440p tests still, it's just going to struggle more and more and future memory demands go up.

That's certainly their positioning. But the 7900XT, 4080, 4070Ti and 4070 are actually all decent too (4070s a bit memory limited) but at least 50% over priced.

still happy with the rx6700xt which surprised me after my rx5700 experience I would have picked the 3070 but circumstances made the 6700 a free upgrade at the time and no 3070's anywhere

fate may have helped me a little there

Something is niggling at me...

RDNA3 is only marginally better than RDNA2 in gaming. The clearest example of this is 7600 compared with 6650XT. Same number of CU, same clock speeds, same memory...and same performance in games.

Yet the 60 CU 7800 (something) is claimed to be beating the 72 CU 6800XT. Why?

Could be that there might be a 7650 XT that will surpass the 6700 XT later on.

Angilion · 20 Jul 2023 at 18:41

There's a "leak" (i.e. unsubstantiated claim) about pricing. $450 for the 7700 (something) and $550 for the 7800 (something). Which would probably be £500 and £600 when you add the +40% pricing for the UK because reasons.

I'm wondering if maybe I should go for it and buy a 6800XT while they're still available. It's that or the 7800 (something) and I'd be a bit miffed if the 7800 (something) turns out to be worse performance, price or both and all the 6800XTs have been sold by the time we know the price and performance of the 7800 (something).

If the leaked performance benchmarks released today for Time Spy are anything to go by, you might as well as the jump in performance just doesn’t justify the extra cost.

The Time Spy benchmark leak I saw was inconclusive because it didn't give any details about the hardware, only a score. Timespy score can vary a lot with the same graphics card and different other hardware, so the score alone is vague. The score given for the 7800 (something) could be better than a 6800XT or worse than a 6800.

The prices are a leak, i.e. an unsubstantiated claim. Besides, even if they are the official MSRP from AMD that could still change at any time up to 5 minutes before release.

And maybe RDNA3 will fare better over time. It should be more powerful than it is. There's a lot of extra hardware in it.

I'm great at making decisions

Clock speeds?

Angilion · 20 Jul 2023 at 20:19

Clock speeds?

Enough to offset a 20% deficit in CUs? 7900XT has faster memory than the 6950XT a wider bus and higher GPU clock speed and 5% more CUs and it's only ~15% higher performance in gaming. Maybe Navi32 clocks very high. Really high.

FoxEye · 20 Jul 2023 at 21:30

Yeah, but we all know how marketing works. If it beats it in 10% of games by 5 FPS, and loses in 90% of games by 105 FPS, it's still "a 6800XT beater"

humbug · 20 Jul 2023 at 21:37

My thinking is it will match the RX 6800XT.

The 7900XTX has 11% higher clock speeds and 25% higher memory speeds vs the 6800XT.

Its actually the same configuration as the RX 6800 tho it will have 19% higher clock speeds than that along with the 25% higher memory speeds.

Look, if its £500 or less, sold. it will be competing with the RTX 4070, cheapest one of those currently £570, to get one that's not like this one... https://www.overclockers.co.uk/inno...dr6x-pci-express-graphics-card-gx-08v-in.html its £600+.

That's true, but it's not marketing. AMD aren't marketing it yet. I think they'll hardly market it at all, just plop it out so they can say they're done with RDNA3.

The "7800 (something) beats a 6800XT" idea is based on speculation and rumours and a single alleged Timespy score that's of dubious use even if it's real. Timespy scores vary a lot in different PCs with the same graphics card.

I'm not sold on the idea that a 60CU RDNA3 card will match a 72CU RDNA2 card in games. There's no sign of that much improvement in the existing RDNA3 cards. Navi31 doesn't do it. Navi33 doesn't do it. Why would Navi32 do it? The 7800 something will have a small advantage in memory bandwidth over the 6800XT, but relative performance will be almost entirely down to the GPU. It's not as though the 6800XT is hobbled by memory bandwidth.

But if it the 7800 (something) doesn't at least match the 6800XT in performance then what is it for? If it only has ~85% of the performance of a 6800XT (due to the lower CU count) then it's at best a 6700XT replacement. Which does make sense, given that the "7900XT" is the actual 6800XT replacement, the actual 7800XT, with the name inflated so the price could be inflated. So the 60CU Navi32 card was meant to be the 6700XT replacement.

You think the clock speed will be higher than that of a 6800XT by enough for that and the faster memory to make up for a 20% lower CU count?

humbug said:
The 7900XTX has 11% higher clock speeds and 25% higher memory speeds vs the 6800XT.

And 33% more CUs.

humbug said:

So it will beat a 6800. But will it match a 6800XT, which will probably be the closest competitor in price?

It will mostly be competing with the 6800XT. At the same price as a 6800XT it would be a better buy. But the next model up in the range is £800+ and that's not the top model in the range so halo pricing doesn't apply. £500 to £800 is a big jump from 3rd place to 2nd place.

That's pretty much how i treat everything until third-party reviews go up.

Prices especially as we've heard how close to launch those can change.

explicit4u · 21 Jul 2023 at 00:59

At this rate my best hope is that the new cards further push down the old range, got my eyes on a RX580 8GB -> RTX 6700XT upgrade but can’t justify it yet at 1080p.

why, give it a week after release and they cut the price of the 7800(which ever variant it is)

Martini1991 · 21 Jul 2023 at 09:38

At this point I'm far more inclined to sell up my PC/Gaming laptop and just buy a ROG Ally with a 4090 XG lol.

seen rx6600xt's go for £80-100 on the secondhand market
