Bilibili hardware tester finds discrepancies between SK hynix and Samsung memory across Radeon 9070 XT models

This is kinda funny, because I've just been trying to find out whether any RX 9070's (non-XT) use Samsung GDDR6. It supposedly runs cooler, which is significant, with VRAM temps being one of the card's weaknesses. Whether I like it or not, I'm probably to end up with a card having SK Hynix, which I'm then going to see if I can down-clock to 19 Gbps - potentially more than twice as bad a performance penalty as if I could've just gotten it with Samsung memory.

Once the card is out-of-warranty, I might see what mods I can do to lower VRAM temps, and then maybe I can clock it back up to its specified frequency.

the 9070 XT is one of the most elusive new GPUs released in 2025, with any models of the card still unavailable anywhere for less than $150 over its $599 MSRP.

Well, I think they burned through inventories imported before tariffs took effect, pretty quickly. The exemption on PC components isn't a total exemption, either, as far as I understand. And I'd assume there are also some card manufacturers taking advantage of the high-demand situation.

But, it's not actually that hard to find. I think it became generally available sooner after launch than the first RTX 5000 models did.

Right now, Newegg has 5 models in stock: brand new and sold by Newegg. The cheapest is $730, which is still a significant markup, but less than the stated amount of $150.

@bit_user If the samsung Vram runs a bit colder than the hynix it's a big win for me...
Here I have ambient temp's over 86 F

Then my Newegg searches are broken because I've been checking daily for weeks and there is never anything cheaper than about $800 unless you count open box items. I just checked and still 799.99 for new anything other than open box items. Extremely limited availability, very over priced, and virtually no selection at all.

Ugh. The one time I didn't include a link... I swear, when I wrote that, there was a model selling for $729.99. It was XT, but I don't remember anything else about it. Obviously, it's sold out or re-priced, now.

Actually, I think it might've been this. The name does seem familiar and the price matches. So, it was probably still in stock, when I wrote that.

I agree that the lowest price is now ~$800. Keep your eyes peels and good luck!

FWIW, here's a non-XT that's only $600 ($50 above MSRP). It's in stock now, and I've also seen it in stock @ this price a couple days ago:

Awesome! So, my GPU loses all of its thermal paste, but at least it's at the top of the list! LOL
