I have been reading this thread and the Ampere threads for a while now. I haven't seen much that could be classed as hype in this thread. Let's look at some facts.
Every single time Nvidia have even a reasonable advantage in GPU performance their prices are set high. Think almost double the price for ~30% performance when they are competing against themselves. 2080 to 2080Ti pricing for example. This is their MO, always has been and always will be. This time we see 3080 priced at less than half the price of the 3090. So Nvidia are low-balling the 3080 and 3070 prices for a very good reason.
For me this alone points at AMD competing with 3080 at a lower price point. Nvidia never do the consumer favours, so if it's priced the way it is then there's a reason for it.
The benchmarks Nvidia leaked are 100% guaranteed to be best case scenario for the 30X0 and worse case for the 20X0. Experience teaches us (well those not prone to hype) that these marketing slides are generally overstated by ~15% or more. For example the Doom scores for the 2080Ti in that leaked performance video had the 2080Ti performing ~15% worse than reality according to some on reddit. Also if we look at actual benchmarks fro earlier this year the 2080Ti was 100+fps average in Doom Eternal 4K Ultra Nightmare. Suddenly we are to believe it is more like mid 80-90 FPS?
So RTX 3080 is likely to be ~40% faster than 2080Ti at rasterisation if we remove the marketing bias official benchmarks usually carry.
- The XBX is RDAN2 with 52 CUs coming in at RTX 2080 Super levels.
- RDNA 2 has higher IPC other other improvements over RDNA1
- Navi 21 should have ~76 - 80 CUs (rumoured)
So even using the XBX as a base we can calculate that Navi 21 should have roughly 50-60% more performance at least. This puts Navi 21 right around 3080 performance.
So not hype, logic.
