According to a report sourced by MyDrivers, NVIDIA is planning to launch its Ampere flagship, the GeForce RTX 3080 Ti next month, sometime in the second or third week, with 12GB of GDDR6X memory and a slightly higher core count compared to the RTX 3080. Thanks to data shared by @kopitekimi on Twitter, we know that the GPU will be based on the GA102 die, same as the RTX 3080 and 3090, with 10,240 FP32 cores and half as many integer cores.
In the latest update, the tipper confirms that the RTX 3080 Ti will have 12GB of GDDR6X memory clocked at 19 Gbps, and wait for it…will also get the Ethereum mining block, cutting the hash rate in half, although as we’ve already explained that’s just bad for everyone, gamers, miners, alike. Furthermore, if the bus width of the 3080 Ti is lower than that of the 3090 (same as the 3080), it’ll pretty much perform the same as the 3080 in cryptomining. Either way, miners have plenty of profitable currencies to choose from so it’s a moot point.
| RTX 3080 | RTX 3080 Ti | RTX 3090 | |
|---|---|---|---|
| FP32 Cores | 8,704 | 10,240 | 10,496 |

In comparison, the RTX 3080 packs 8,704 FP32 cores and 4,352 integer cores paired with 10 GB of GDDR6X memory via a 320-bit bus. The memory runs at 19 Gbps, the same as the upcoming 3080 Ti. There’s a chance that NVIDIA could use a 352-bit (slightly lower than the full-fledged 384-bit on the 3090) using clamshell mode, but even then the performance delta between the 3080 and 3080 Ti shouldn’t be more than 10%. And that’s a best-case scenario we’re looking at. I can easily see NVIDIA selling the 3080 Ti for $999 despite a minor uplift over the 3080 and call it a day. And the fact that supply is extremely limited for the time being is just the icing on the cake. It’ll drive even more gamers/miners towards the 3080 Ti and given the higher profit margin, it means more money for NV.
