Really too bad about that Gigabyte model, but I DID warn you about that didn't I?   

TPU Link for anyone that would like to see what was going on with his Gigabyte card:
https://www.techpowerup.com/forums/threads/gigabyte-has-fallen.320080/

TLDR:  BUY A GIGABYTE CARD IN 2024 AT YOUR OWN RISK (Labrat here isn't the only one reporting MAJOR problems with Gigabyte cards).

 

------------------------------------------------------------

 

Glad you've got the Sapphire Nitro+ model now, I get the feeling you're in for a GOOD time with that card!

Now, let's see your benches.  You're probably the only person on EHW with one of these.

Driver Updates - Unlocked VRAM OCing

AMD's latest 24.3.1s have lifted the VRAM OC limits for the GRE, and most-all cards will clock 2500-2600MHz+

I'd like to submit a petition to perhaps change this to a general 7900 club?

There's only two 7900GRE's on site I believe so far......   

Up to you of course, not my club.

It's a solid enough card as a slot in between the 7900XT and the 7800XT. But looking at the performance vs the 4070 and 4070 Super I think the price is kind of a hard sell for what you give up in RT. It's not terrible, but it's definitely a worse card if RT matters for you and I think the 16GB vs 12GB argument at this price segment is less important. So asking for the same money as a 4070...I don't know. Its also considerably more power consumption than the 4070 and 4070 Super under load, so I don't see a win there either.

 

I guess if 12GB vs 16GB is make or break for your use case, otherwise I don't know, not excited about this card at $550.

Thing is, the GRE is faster, generally (in rasterization) and does RT 'fine' w/ XeSS or FSR Scaling (or lower Native-res. 1080p 144hz, here)

The GRE should in theory, be capable of doing RT titles as well as any other 7900 series card I'd think.  They're all Navi 31 cards afterall.  It's a tad cut down in terms of shaders and all that jazz, sure.  But its still a full fat Navi 31.  I'm not sure which portion of the card is responsible for the RT performance on the 7900 series cards, but its not cut down THAT badly.

With that said, yes Nvidia cards are doing RT better.  We all know that.  At 5120x1440 / 120Hz, I have zero complaints about the RT performance on my 7900xtx though.  It could be better, yes.  But I knew RT was a bonus when buying this card, and it does the job well enough with FSR / frame scaling.  Last gen's AMD cards were an absolute joke with RT performance.  At least the 7900 series are capable of PLAYING the titles with RT enabled.  I want to say the 7900 xtx is approximately on par with a 3090 or so in RT performance?  Please correct me if I'm wrong, but the performance really isn't bad for RT titles.

IDK if we'll ever see actual feature parity between AMD and Nvidia. We're at the point where AMD does all the same stuff albeit a gen behind. 

 

And that's fine for most people. Sure it's fun to crank the settings in Cyberpunk and go stare at some neon sign reflections in a puddle of water, but at some point you just want to play through your backlog of games. I DO have mostly nvidia cards and I still don't bother with ray tracing. 

 

If it weren't for the lackluster Folding@home performance and higher power draw, I'd buy more AMD cards. The GRE will drop to $500 before Ngreedia ever drops the price of the 4070 Super. As it sits, I think it's an OK option for a lot of people.

Yes I agree its the faster raster card, but its definitely a worse card for RT w/ FSR.

It's Navi31 sure, but I wouldn't call it "full fat". That's the 7900XTX. Its 80 compute units for the GRE vs 96 on the XTX, not to mention a reduction in memory bandwidth from 384-bit to 256-bit.

 

The architecture is basically that each compute unit has a ray accelerator, so it is 80 vs 96. That's about a 17% cut-down on the GRE.

 

Sure we can all say "its not that bad" but its still for all intents and purposes a generation behind which is why I think trying to slot in price wise to Nvidia's current gen really isn't all that compelling to me.

Yeah I just feel like that "generation behind" on RT / FSR like features makes these launch MSRPs for AMD cards really lackluster - they are after all pricing within Nvidia's current generation.

 

I can at least say the price usually course corrects, unlike Nvidia.
