AMD RX 7600 XT Rumored With Navi 32 and 12GB or 10GB VRAM

A new EEC listing from PowerColor features the RX 7600 XT model name, including versions with both 10GB and 12GB memory capacities. (Hat tip to @harukaze5719 on X.) The Eurasian Economic Commission listing also includes an assortment of RX 7800 XT and RX 7700 XT models, with the former now ranking among the best graphics cards.

PowerColor unveiled four RX 7600 XT models in total, with two featuring 10GB capacities and the other two featuring 12GB. The model names are RX7600XT 12G-L/OC, RX7600XT 12G-F, RX7600XT 10G-L/OC, and RX7600XT 10G-F. Assuming these models are actually legitimate, it means AMD is working on an RX 7600 XT that will have more VRAM than the RX 7600, and possibly the same memory capacity as the RX 7700 XT (12GB).

Do note that EEC listings are often more placeholders than actual specs, however, so it's entirely possible the RX 7600 XT won't even materialize. From what we've seen of previous filings, it appears manufacturers can publish any name they want to the EEU/EEC, even if it's a made-up name based on educated guesses. This allows names of future graphics card models to be processed earlier if the manufacturer guesses correctly. Plus, there are good reasons for AMD to have such a card, like the $200 price gap between the RX 7600 and the RX 7700 XT.

AMD has not yet announced an RX 7600 XT, and recently SVP Scott Herkelman even said that the RDNA 3 lineup was "now complete." But there's always room for another intermediate GPU, if yields and market conditions allow for it, and in that same article Scott noted that it was possible AMD might develop more graphics cards based on its current Navi 31, 32, and 33 graphics dies — beyond the RX 7800 XT and 7700 XT. We're not sure if he was talking specifically about the RX 7600 XT, but it's as good of a hint as any.

If AMD goes through with an RX 7600 XT, a 12GB seems far more likely than a 10GB variant. The problem with a 10GB capacity is that it doesn't divide well into an RDNA 3 GPU featuring a Navi 32 die. A Navi 32 GPU features up to eight GDDR6 chips split up between four MCDs (Memory Cache Dies), with each MCD controlling two GDDR6 ICs. To get to 10GB, that would mean disabling one full MCD and half of a second MCD, which could create idiosyncrasies due to the non-uniform L3 cache sizes. 12GB spread across three fully utilized MCDs would make far more sense for a potential RX 7600 XT.

That means a hypothetical RX 7600 XT would look very similar to a RX 7700 XT, featuring the same memory capacity and bus width but packing fewer RDNA 3 Compute Units. There's a big gap between the RX 7600's 32 CUs and the RX 7700 XT's 54 CUs, leaving plenty of room for a potential RX 7600 XT with somewhere around 42–46 CUs. Navi 32 is also the only sensible option, since the vanilla RX 7600 already comes with a fully enabled Navi 33 die.

While we don't have any rumored specs, AMD has plenty of options for how to configure and price an intermediate RX 7600 XT. Price it around the $350 mark, give it 12GB of VRAM, maybe even clock the VRAM a bit lower than the RX 7700 XT if that would reduce pricing. Then use 42 CUs, give or take, with a more modest clock than the 7700 XT, and we could potentially have an RX 6750 XT replacement with better efficiency and performance. Will we actually get such a card? Only time will tell.

    12GB on Navi 33/128bits is possible if AMD got their hands on 24Gbits GDDR6.

    AMD will probably release this otherwise they don't have anything to compete at the same price as the 4060 ti 8gb.

    While non-power-of-two DDR5 memory now exists, I don't believe anyone has done that with GDDR6 yet. Correct me if I'm wrong. Theoretically, it's possible, but until it actually gets manufactured we will only have the standard power of two increments (barring non-uniform configurations like some of the old Nvidia GPUs where you had 2GB courtesy of four 2Gb chips and two 4Gb chips).

    Or they could just set the price of the 7700XT to 400 (like it should be), and that'd compete very nicely, and generally exceed it when you don't count RT, which we shouldn't be on these cards cos they're all kind of rubbish at that, let's face it.

    That is, in my opinion, all that's needed to make the 7700 a great card this generation - though I admit that's not a very high bar to overcome.

    Nvidia is about to pull an Intel and get complacent and offer very incremental upgrades if AMD doesn't do something.

    That would be the nice approach. But more likely AMD wants to keep prices as high as it can, and a $350 RX 7600 XT that's 20% slower than the 7700 XT would fill out the product stack and still potentially encourage people to consider the higher priced card. And if you're considering the 7700 XT, then maybe just go for the 7800 XT instead...

    We shall see, but it feels like the 7700 XT mostly exists right now to push people to the 7800 XT. Watch AMD do a $379 RX 7700 12GB instead.

    6700 XT same raster, same 12GB, $275 like new. This card coming out at $350 will be just "about right". The same cannot be said about the 7700 XT though as it's virtually a downgraded RX6800 whichs about $375 at ebay right now. The 7700XT definetly isn't worth more than $400. I'd choose 6700XT or RX6800 any day ober these, same goes fir the 6800XT vs 7800XT!

    24Gbits (and 32Gbits) GDDR7 already exists, slapping a GDDR6 bus interface between the cell arrays and IO pins is a relatively minor design change as they already have all of that too from previous products.

    That chip is a single die? Don't like these new glued chips.

    Is it? Because what I've learned over the years is that few changes are "minor" when it comes to cutting edge tech — of which GDDR7 most certainly is a part. I'd file this as "theoretically possible but completely unlikely to ever happen." We'll get products with native GDDR7 support long before anyone backports GDDR7 onto a GDDR6 memory controller with some separate chip doing the translation. That's my bet.

    But besides that... I've found zero sources indicating that Samsung (or anyone else) has actually talked about doing 24Gb / 3GB GDDR7 modules. The closest thing I can find is people wondering if Samsung might offer such capacities. The only official announcement about GDDR7 that I've found talks about 32Gbps GDDR7 speeds (which is slightly slower than earlier rumors of 36Gbps speeds):

    If you have a source saying 24Gb GDDR7 modules are actually confirmed, I'd love to see it! As in, I'm interested in seeing it, not that I'm questioning you or anything. I definitely can't recall seeing anything other than speculation about the possibility.
