Any news on 7800 xt?

[Jay85]

Anyone starting to suspect that the 7900 GRE is AMD testing the waters for what's going to be the 7800 XT?

AMD Radeon RX 7900 GRE ASIC Smaller than Navi 31, Slightly Larger than Navi 21

The GPU at the heart of the China-exclusive AMD Radeon RX 7900 GRE (Golden Rabbit Edition) sparked much curiosity. It is a physically different GPU from the one found in desktop Radeon RX 7900 XT and RX 7900 XTX graphics cards. AMD wouldn't go through all that effort designing a whole different...

AMD's Radeon RX 7900 GRE Gets Benchmarked

AMD's China exclusive Radeon RX 7900 GRE has been put through its paces by Expreview and the US$740 equivalent card should in short not carry the 7900-series moniker. In most of the tests, the card performs like a Raden RX 6950 XT or worse, with it being beaten by the Radeon RX 6800 XT in 3D...

$649 for a card that near enough matches the 4070 or at best beats it by a 10'ish percent.

Trying to pull an Nvidia i suspect.

Personally, I'm waiting for the RX 7700 7900 Flying Pink Unicorn edition.

You sure its not the Couldn't Give A Flying **** edition by AMD?

7800xt unveiled by Powercolor

It has 25% less cores than the 7900GRE but the same memory configuration and clocks

Given the 7900gre is only 10% faster than a 6800xt, it's looking like the 7800xt will either be on par or slower than the 6800xt. The 7800xt is a replacement for the 6800 and imo should be priced at $399

PowerColor Leak Confirms AMD Radeon RX 7800 XT GPU: 3840 Cores & 16 GB VRAM

PowerColor has leaked AMD's upcoming Radeon RX 7800 XT graphics card which features a brand new RDNA 3 GPU SKU with 16 GB VRAM.

It should be priced at $399, but it won't.

 

[uscool]

Probably £50 lower than the 4070

 

[Doop!]

They couldn't release it slower than the 6800XT, could they?

This surely???

 

[humbug]

The GRE? its got the same amount of CU's, Bus Width and memory speed as the 6950XT.

in terms of specifications its identical, other than core clocks, boost clock is 65Mhz lower.

Here are the qHD figures for the RX7900GRE:

https://www.techpowerup.com/img/y84B0404PNVkfXh9.jpg

The RTX4070/RX6800XT are 88% of the RX7900GRE,which makes it around 14% faster overall. The same review puts the RX7900XT at 24% faster than the RX7900GRE.

But if you look at the TFLOPs difference:

AMD Radeon RX 7900 GRE Specs

AMD Navi 31, 2245 MHz, 5120 Cores, 320 TMUs, 160 ROPs, 16384 MB GDDR6, 2250 MHz, 256 bit

www.techpowerup.com

AMD Radeon RX 7900 XT Specs

AMD Navi 31, 2394 MHz, 5376 Cores, 336 TMUs, 192 ROPs, 20480 MB GDDR6, 2500 MHz, 320 bit

www.techpowerup.com

Only a 12% difference,showing Navi 31 is severely constrained by the memory subsystem,ie,only 72% of the memory bandwidth of the RX7900XT.

The RX7800XT has the same memory bandwidth,and the core is also clocked higher. If it is more balanced of a core WRT to memory bandwidth it might possibly be closer at lower resolutions.

However,as the RX7900GRE is at $650 already I can't see it beating an RTX4070. So whatever price the RX7800XT is,it needs to be cheaper,unless OFC the core actually clocks closer to 3GHZ during games.

I don't understand why they don't release the GRE as 7800xt and the 7800xt as the 7800.

Naming patterns seem to be all over the shop

Sounds like they are finding a way to dump Navi 32 dies. It will be actually interesting to see if Navi 32 can clock close to 3GHZ during normal gameplay(or not).

copying nvidia - surely its a misprint and it should read 7700XT.

Apologies for my dimness, what do you mean dumping the navi32 dies?

Less infinity cache as well though

Oops,I meant Navi 31 dies not Navi 32 and the RX7900GRE.

AMD might have produced too many of them,and have a bunch of defective dies to get rid off. So are making a weird SKU which is neither here nor there and dumping it in China and to some system integrators.

I remember,many years ago they made the HD7870LE/HD7870XT,which used a cut down large die in a similar way:

AMD Radeon HD 7870 XT Specs

AMD Tahiti, 975 MHz, 1536 Cores, 96 TMUs, 32 ROPs, 2048 MB GDDR5, 1500 MHz, 256 bit

www.techpowerup.com

It was only slightly faster than the midrange HD7870:

AMD Radeon HD 7870 GHz Edition Specs

AMD Pitcairn, 1000 MHz, 1280 Cores, 80 TMUs, 32 ROPs, 2048 MB GDDR5, 1200 MHz, 256 bit

www.techpowerup.com

The HD7870LE/HD7870XT was not much faster than the HD7870 and it appeared to be unbalanced in specifications.

I couldn't work that out either the GRE card is a Navi31 die.

Someone has got to have got their wires crossed, noway a new mid range card is going to be slower then the card it's nominally replacing. I reckon the specs that were quoted are for a 7800 non XT and the XT will feature the full Navi32 die.

A 7800XT being on par with a 6800XT is completely embarrassing,it's pointless even releasing it

Only real benefit will be that it uses less power. That's exactly what Nvidia is doing as well. I'd guess that the 7800xt will end up using 100w less in games than the 6800xt, so yeah instead of more performance AMD just gives you lower power draw which is exactly what Nvidia is doing with everything under the 4070ti

 

[JediFragger]

Nah the architecture is not power efficient enough to use less than 200w imo, at a guess I'd say 50/60w less.

Nvidia 4xxx also has DLSS3, which gives a huge "performance" increase over corresponding 3xxx cards. Not really, but it counts for marketing purposes and it is useful. Especially for hobbled underpowered cards. Like most of the 4000 series.

AMD 7xxx has better ray tracing than the 6xxx cards, but that's not counting for much.
