This also required some tweaks to the PCB layout, so the 3070 Ti doesn't use the exact same boards as the 30 Ti. In comparison, the 3070 just used two fans on the same side of the card. Basically, the 3070 Ti has a flow-through cooling fan at the 'back' of the card, similar to the 30 Founders Edition cards. Unlike the RTX 3080 Ti, Nvidia actually made some changes to the RTX 3070 Ti's design. (Yeah, I know, but the RTX 3060 12GB remains a bit of an anomaly in that department.) GeForce RTX 3070 Ti Design: A Blend of the 30 And with the 30 Ti offering 10GB and 12GB, respectively, there was basically no chance Nvidia would equip a lesser GPU with more GDDR6X memory. The 256-bit interface means Nvidia can do 8GB or 16GB - nothing in between. The difficulty is that there's no good way to get more memory other than simply doing it. But a few judicious tweaks to settings (like dropping texture quality a notch) will generally suffice.
Not surprisingly, many of those come in games promoted by AMD, it's almost like AMD has convinced developers to target 12GB or 16GB of VRAM at maximum quality settings. These days, we'd say it's sufficient for any game you want to play, but there are definitely instances where you'll run into memory capacity issues. There's still the question of whether 8GB of memory is enough. Some of it also allows for slightly higher clocks, but generally, that's a significant increase in TDP just for a change in VRAM.
It's a bit shocking to see that the 3070 Ti has a 70W higher TDP than the 3070, and we'd assume nearly all of that goes into the GDDR6X memory. In general, we expect performance to land between the 30, but closer to the 3070.īesides performance specs, it's also important to look at power. More important by far is that the 3070 Ti goes from 14Gbps of GDDR6 and 448 GB/s of bandwidth to 19Gbps GDDR6X and 608 GB/s of bandwidth, a 36% improvement. It also has slightly higher clocks, giving it 7% more TFLOPS - and it still has 27% fewer TFLOPS than the 3080. The GeForce RTX 3070 Ti provides just a bit more theoretical computational performance than the 3070, thanks to the addition of two more SMs. Will that happen before the next-gen GPUs arrive? Probably, but only because the next-gen GPUs are likely to be pushed back thanks to the same shortages facing current-gen chips. Nvidia is also producing more Turing GPUs right now, mostly for the CMP line of miner cards, and at some point, supply should catch up. By launching the RTX 3070 Ti, with its binned GA104 chips and GDDR6X memory, Nvidia continues to steadily increase the number of GPUs it's selling. The gamers among us will certainly hope so, but even without crypto coin mining, demand for GPUs continues to greatly exceed supply. That's still enough for the cards to 'break even' in about six months, but again, profitability has dropped and may continue to drop. Profitability should be a bit higher with tuning, but right now, we'd estimate making only $3.50 or so per day.

With the limiter in place, Ravencoin (KAWPOW) and Conflux (Octopus) are the most profitable crypto coins right now, and both of those hashing algorithms still appear to run at full speed. The good news, depending on your perspective, is that mining profitability has dropped significantly during the past month, which means cards like the RTX 3090 are now making under $7 per day after power costs, and the RTX 3080 has dropped down to just over $5 per day.Įven if the RTX 3070 Ti didn't have a limited hashrate, it would only net about $4.25 a day. Or maybe they're just optimistic about where crypto is going in the future. Maybe they made too much money off of the jump in crypto prices during the past six months.

Maybe they hope the limiter will be cracked or accidentally unlocked again. In fact, miners are probably still trying to buy the limited RTX 3080 Ti, 3080, 3070, 3060 Ti, and 3060 cards. Will it be enough to avoid having the cards immediately sell out at launch? Let me think about that, no. Nvidia has also implemented its Ethereum hashrate limiter, basically cutting mining performance in half on crypto coins that use the Ethash / Dagger-Hashimoto algorithm. While Nvidia could have tried doing this last year, both the RTX 3080 and RTX 3090 were already struggling to get enough GDDR6X memory, and delaying by nine months allowed Nvidia to build up enough inventory of both the GPU and memory for this launch. Nvidia takes the GA104 GPU that powers the RTX 3070 and RTX 3060 Ti, only this time it's the full 48 SM variant of the chip, and pairs it with GDDR6X. The basic idea behind the RTX 3070 Ti is simple enough.
