In terms of nitty-gritty specifications, we’ll start with the RTX 3070. If this leak is true, the card should ship with 8GB of GDDR6 VRAM clocked at 16 Gbps, across a 256-bit memory bus. The TGP should be about 220W, though the CUDA Core count and boost clock speed are unknown at the moment.
Moving on to the RTX 3080, we’re looking at 10GB of GDDR6X VRAM (clocked at 19 Gbps), a 320-bit memory bus, 4352 CUDA cores, a boost clock of 1710 MHz, and a TGP of 320W. Videocardz says a second variant of the 3080 with twice the memory (20GB in total) is also in development, but it was unable to determine when the card might release.
The final leaked SKU, the RTX 3090, is an absolute monster. It’s expected to have 5248 CUDA cores, a boost clock of 1695 MHz, a whopping 24GB of GDDR6X VRAM clocked at 19.5 Gbps, a 384-bit memory bus, and a TGP of 350W. Memory bandwidth for the 3070, 3080, and 3090 should be 512 GB/s, 760 GB/s, and 936 GB/s, respectively.
They really can’t screw up this time, the dies are large, ray tracing mature, and the api’s finally fleshed out. I am expecting a real generational improvement this time around.
Hopefully I don’t eat my words, I am expecting a real generational improvement in terms of price to performance as well.
if indeed the 3070 is as fast or faster than a 2080 ti, that’s like a 25% performance increase for the same money, and RTX performance will actually be usable.
The only market segment they need to worry about is the RTX 3070.
They need a 2080ti level performer with competent ray tracing at or around $450.
If they can’t then they’ll be forced to try to dominate the sub $300 market, which if Nvidia’s GTX lineup will also be absent RTX features, i’m sure they can do.
