Could be they are holding back on bigger cores, waiting for nvidia's response.
Or they just prefer to make as many smaller cards as they can, as they might be going into console cores building as well.
3090 will beat 2080 not 2080Ti. VII will have higher bandwith over GDDR6 3080/3090. Besides, we don't need a faster 2080Ti we need a cheaper 2080Ti. This will sell like hotcakes. AMD is going for market saturation, not the performance crown right now.

I certainly don't think they will achieve that, but that's what the post claims.

Look at how much faster VII is vs Vega 64. Not much. 1TB/s does not help it in games. We will have to wait and see but I still think AMD needs to beat 2080 Ti.

How is it no way they can achieved that when R7 is not even a fully unlocked GPU? They have 60 CUs, but the full die is 64.


3090 will certainty beat the R7 if it comes unlocked and on a faster, more advanced process. They just need to sort out their bandwidth limitation.

If they bring 2060/2070/2080 performance but at really affordable prices then they've got themselves a winner.

I know with my V64 at 1050mhz HBM2 (537.6GB/s bandwidth), any gains past that point were minimal at 3200x1800 or higher and far less than noticeable lower than that. Mind you my gpu sits at 1630mhz so it's a bit slower than a VII clock speed wise but I've got the full fat 64CU too which from research was never really a benefit compared to the V56 as scores/fps are near identical clock for clock.

Any idea what kind of bandwidth speeds GDDR6 would typically produce assuming a 256bit bus and average clocks (I know, this is not exactly an easy request)?

I did see quite nice gains, atleast in BFV going from 945mhz mem to 1050 so i'd imagine faster clocks, the full 64CU's but being limited to less bandwidth would really kill some performance, at least at higher res. Also, despite the move to 7nm it's not like VII is a low power gpu. GDDR6 is only going to increase this so I'd imagine Navi would have memory clocks on the reserved side.

Edit:

Forgot the 2080 used GDDR6 w/ a 256bit bus. So assuming the same 14ghz we are talking 448gb/s when a stock clocked V64 is at 483.8gb/s. Considering the gains I saw going up 53.8gb/s I can't imagine Navi being much faster than a V64 with less bandwidth despite a fairly large jump in clock speed.

VII is faster than a half decent V64 but in all reality, it's certainly not earth shattering. At stock it has double the bandwidth (still blows my mind to see over 1,000gb/s on a GPU) and a boost clock barely over 100mhz faster than a stock liquid cooled V64 (which face it, those speeds are typically easy enough to achieve on any V64).

Navi is going to have to be priced really well to sell or it's going to have to pull a high clock trick out of it's hat.

Anything faster than RTX 2070 is really optimistic. Radeon VII was aiming at RTX 2080 after all.

However, I'm sure there's a market for a GPU that has close to RTX 2070 performance with more VRAM at RTX 2060 pricing.

@ SoloCamo, RTX 2070 is on GDDR6 with 256-bit memory bus and so is the RTX 2080.

https://www.techpowerup.com/gpu-spec...rtx-2080.c3224 , about 448 GB/s

Judging from CES 2019, we know how disappointing the truth is than rumor. Expecting a gpu as good as 2080ti for lower price, end up getting 2080's level for the same ridiculous price.. I wouldn't be surprised if the rx 3080 end up slower than 2070 and priced just as absurd.

Thanks for confirming, caught it and edited it moments prior.

Navi is going to have to be quite the interesting card to gain sales.
