AMD Radeon RX 7800 XT and RX 7700 XT Reference Design Pictured

[btarunr]

AMD, in a now-deleted tweet, revealed what it is probably going to announce later today—the Radeon RX 7800 XT and RX 7700 XT desktop graphics cards. The company briefly tweeted the marketing flier for these cards, before deleting it, but not before VideoCardz saved a copy. This flier confirms the SKU names RX 7800 XT and RX 7700 XT up for launch; and gives us two images of the Made by AMD (reference design) graphics card. It appears like AMD is using a common board design for both SKUs.

The reference Radeon RX 7800 XT appears to be a slightly shrunk down version of the RX 7900 XT reference. The dual-slot card comes with two axial-flow fans instead of three on the RX 7900 XT. The card draws power from two 8-pin PCIe power connectors. Earlier this month, a leak by PowerColor spilled the beans on the RX 7800 XT being based on the "Navi 32" silicon. A chiplet-based GPU just like the "Navi 31" powering the RX 7900 series; the Navi 32 is maxed out by the RX 7800 XT, and packs 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 64 MB of Infinity Cache memory, and a 256-bit GDDR6 memory interface, which holds 16 GB of memory on the RX 7800 XT. Specs of the RX 7700 XT remain under the wraps.

The 7900XTX and 7900XT landed with 6 and 5 memory chiplets, 96MB and 80MB cache, 384 bit and 320 memory interfaces, and 24GB and 20GB VRAM respectively. So 4 memory chiplets, 64MB cache, 256 bit interface, and 16GB of VRAM is pretty expected for the 7800XT at this point. Compare to the 6800XT, the memory hasn't improved much, just a 10% higher frequency. And the core count is down. The 6800XT used Navi 21 whereas this is Navi 32.

not going to be a good value proposition against RDNA2 cards

I'm wondering if this cooler design is gonna be enough considering that the reference 6750 XT has three fans that are already barely adequate.

 

[Kirederf]

If the RX 7800 XT also comes with this (ugly) dual cooler design, than AMD is basically admitting that the RX 7800 XT really is an RX 7700 XT.. The real RX 7800 XT is the RX 7900 GRE / XT..

 

[Broken Processor]

I don't care what they call it, it's not a 7800 xt and they know it. AMD screwed there entire lineup this gen and instead of admitting it they have doubled down. Regardless of the name if it's priced right it will sell but who am I kidding it's AMD 2023 it won't be.

A link to where you got that info pls

First-hand experience (see my system specs). How do you like a 102-105 °C hotspot at stock? Even the weakest AIB cards can do much better than this.

LMAO at the "partner logo" box on the image. Yeah, someone jumped the gun there.

I can't find any reference models of the 6750XT were they even available ? And I honestly doubt they were that much different than the rest, 100C hotspot isn't that uncommon even on AIB cards.

My reference 7900XT reached 100C hotspot too when overclocked on a hot day, isn't that big of a deal.

AMD sells a reference 6750 XT directly.

Also your reference 7900 XT shouldn't be hitting 100C hotspot at all unless you have really bad airflow in your PC case. I know the earlier MBA 7900 XTX had a faulty HSF that had this problem (mine does not have this as it seems to be the newer revision post-April), but I never heard of the MBA 7900 XTs having a hotspot problem.

It ran at like 80-82C stock, when overclocked it would hit 100C. Hot spot temperatures increase disproportionally with power consumption it seems, on water at stock it runs at about 60-65C but then once overclocked it shoots up to 70-75C even though the edge temperature stays almost the same.

This goes to a page not found for me, I guess it's location dependent.

tbh the 6750xt was pushed past its optimal efficiency range by AMD. It uses way more power than a 6800, about par with a 6800XT

 

[Frick]

Any idea when it'll actually released?

 

[Macro Device]

RX 7900 GRE

No, this is the real RX 7800 non-XT. RX 7900 XT is the real 7800 XT. The 7800 XT is the real 7700 XT. The 7700 XT must be the real 7600 XT, whereas 7600 is the real 7500 XT.

Regardless of the name if it's priced right it will sell but who am I kidding it's AMD 2023 it won't be.

A million times yes.

 

[Space Lynx]

will be interesting to see prices on the 7800 xt. 7900 xt was only $705 recently on Prime Day sales (no tax either cause of prime visa/prime day combo)... so if this comes in at $499 it makes sense, but at $599 it really doesn't make any sense.

my 7900 xt has been rock solid for me, just can't really use the OC bios mode unless you set fan speed at unreasonably loud levels. on default bios its the coldest 7900 xt there is though, my temps match the guru3d review of same exact model that i have on default bios as well as the scores. with a mild/medium oc it matches a 7900 xtx in many games i have tested. pretty happy with it.

That's pretty garbage bro. My 6800xt when OCed this a 82c hotspot temp. 100c hotspot just shouldnt be happening on a competent cooler, especially on such a large surface area die.

It will NOT sell even if it priced right. People buy Nvidia logo hardware, laught at AMD hardware, because "it lacks DLSS, it doesn't offer CUDA, it draws more wattage which is a problem only when AMD does it, it's slower in RayTracing, it doesn't have good drivers, it breaks for no reason, it is incompatible, AMD's logo is not shinny enough, AMD hardware is for peasants, someone told me that only Nvidia exists" and stuff.
So even if the final price was taking in consideration all the above reasons, even the non logical, people would invent 10 more reasons to go with an Nvidia card. Even a slower, more expensive Nvidia model instead of buying an AMD one.

will be interesting to see prices on the 7800 xt.

I would expect a price close to current 6800 XT with a minor premium for the 7800 XT, so $529-$549 and a higher price than the current price for the 6750 XT, meaning $399 for the 7700XT.

The fun part will be AMD avoiding comparing these new GPUs with RDNA2 models, but choosing to compare with RTX 4060 Tis, 7700XT against the 8GB Nvidia model and 7800 XT against the 16GB Nvidia model.

even with medium oc on default bios my 7900 xt never breaks 84 celsius hot spot in most demanding games. on oc bios it will hit mid 90's celsius with heavy oc.

but with default bios and no oc, it never breaks 75 celsius on hotpsot in same demanding games.

pretty good card over reference model. but yeah, I do envy Nvidia for its cold temps. overall pretty happy with my card though

For all the talk of "competition', it doesnt seem to be helping here. AMD seems really content to remain in a VERY distant 2nd place to nvidia.

Glad I jumped on rDNA2.

huh? my 7900 xt with medium oc beats a 4090 in ac valhalla and damn near matches it in shadow of tomb raider. i wouldn't call that very distant second place. at 1440p anyway.

 

[alphaLONE]

Come on, I can't be the only one to notice AI image generation artefacts on the card on the bottom right and on the "RADEON" text in the PC. Same thing for the AMD logos on the fans, they're off!

It will be a suicidal move if they try to do a price war with Nvidia. Not to mention that if Nvidia wasn't reacting and the price war was a success, driving buyers to AMD GPUs, AMD will be facing another problem. To allocate wafers to cover the extra demand for a product line that probably doesn't bring enough profits.

But profits is not the most important. Now AMD has a more improtant task - to stay relevant in the graphics business, and this can only be achieved by good marketing strategy, and gaining more market/mind share.


I think AMD run out of ideas, everything they do is wrong these days.

Radeon RX 7800 XT with its 3840 shaders is actually a downgrade from RX 6800 XT with as many as 4608 shaders - this is 768 shaders LESS and almost 20% LESS.
Radeon RX 7700 XT with its miserable 12 GB VRAM is also not good enough, no matter how much they beefed the specs elsewhere.

Both cards should be DOA as we speak

It was available at Scan UK for a few months a while back.

I'm not saying it's the end of the world, just that AIB 6750 XTs can do a lot better.

It ran at like 80-82C stock, when overclocked it would hit 100C. Hot spot temperatures increase disproportionally with power consumption it seems, on water at stock it runs at about 60-65C but then once overclocked it shoots up to 70-75C even though the edge temperature stays almost the same.

That's what I mean. The reference 6750 XT reaches 100 °C at stock (with no overclock).

For all the talk of "competition', it doesnt seem to be helping here. AMD seems really content to remain in a VERY distant 2nd place to nvidia.

Everybody seems to be hung up on the fact that AMD is a distant second, but that doesn't mean they're not making a profit. It's a smaller company than Nvidia, after all. Dominating a market isn't everything.
