AMD engineers posted some code updates here: https://github.com/ROCmSoftwarePlatform
that contained the following lines:

These should pair up with the 7800 series cards and the 7600/7700 mobile parts.
 
Considering the 7800xt seem to be an Navi 32, that does leave room for an 7700xt Navi 33:

Apparently there a rumors that Navi 32 is not ready so it could take a giant while.

Or it would make the Navi 32 stack quite long from 7800xt to 7600xt, from a size mature node for which I am not sure has much yield to be gained to bin that low versus making a simple 203mm Navi 33.

Will be interesting to see how well they will price that 7800xt, 83% the core count, half the cache (if techpowerup is right), the costly die part less than 40% the size of 6800xt, 75% of the ram and bus, seem to be aggressive on power-clock to perform while going all-in 4080 12gb style to cut price, maybe that where they reach the 3ghz on the smaller die.

A return to an actual $500 top end mid range (not sure it actually happened in 2020 for people to be able to buy a $500 3070 without making a line or having an online strategy) card would be nice.
 
Both 7800xt & 7700xt could be derived from Navi 32

Navi 33 could be 7600xt
Could be I imagine the tech power up are just putting best guess rumors has a place holder.

I guess it depend how well the chiplets work and stop to make sense,a really small Navi 32 tsmc 5nm could make it that a 7800xt and 7800 is more than enough to have an excellent yield and save money on the 7700xt going navi 33 right away.
 
Speculation by Igor that AMD is facing issue with the market positioning of (multi-chip) Navi 32

Add it to claim by Lakados that AMD has 6 months worth of RDNA 2 stock & it looks like they are in a pickle regarding Navi 32 situation


The way I see it, AMD has below options:
  1. Take the L, sell 2 Navi 32 cards for as low margin as possible(or loss?)
  2. Take the RDNA 1 approach, skip Navi 32, sell discounted RDNA 2 & shift focus to RDNA 4
  3. Spend some time to fix "bugs" in mcd/navi 32 & then sell Navi 32 with "fixed" performance for higher price (this is probably what AMD is doing now)
  4. Go for fallback option. Make Navi 32 as monolithic RDNA 3 chip but on 6nm (unlikely, but also a practical option for AMD if RDNA 3 multi-chip issues are not worth spending effort to fix)
Speculation from Igor:

AMD not confident of selling Navi 32 (7800xt/7700xt) for a profit. Might introduce Navi 33 (7600xt) first in computex.

NVIDIA stops supply of chips, the RTX 4060 Ti comes at the end of May/beginning of June and AMD shows the RX 7600 at Computex​

I kinda don’t see a stockpile of RDNA 2 as a “problem”. Unless of course they’re selling at a loss and they think they could sell newer parts for a profit.

6900XT/6950XT are tremendous bargains right now. If nVidia actually had 3080/3090/Ti’s lying around right now they also likely wouldn’t launch new product and enjoy coasting. Those cards for nVidia actually sold out as they are (were) reasonably priced as compared to everything thats coming from Lovelace.
