Nvidia GeForce RTX 3080 Ti Specifications

The Nvidia GeForce RTX 3080 Ti is the "poor man's" take on the RTX 3090. For gaming purposes, it delivers very similar performance as very few games actually use more than 12GB of VRAM. It uses the same GA102 GPU, only with 80 SMs instead of the 82 enabled in the RTX 3090. It also uses twelve 1GB (8Gb) GDDR6X memory chips rated for 19 Gbps. You can see where the RTX 3080 Ti ranks among other cards in our GPU performance hierarchy.

While the above image shows the RTX 3080 Ti Founders Edition, that's a very poor choice of card for the 3080 Ti. It has the same basic size and cooling capabilities as the RTX 3080, but with more cores and higher clockspeeds plus more GDDR6X chips, it runs very hot and gets quite loud. I recommend looking at the various AIC (add-in card) partner offerings for better 3080 Ti models.

Launch Price$1,199

Launched about nine months after the Ampere architecture first arrived, the RTX 3080 Ti likely would have replaced the RTX 3080 in pricing, or perhaps it would have cost a bit more. However, the cryptocurrency boom of 2021 was in full swing and every graphics card was sold out. Nvidia opted to use a recommended price of $1,199, but all the cards immediately sold out and ended up going for closer to $2,000 — this despite the implementation of Nvidia's Lite Hash Rate (LHR) anti-Ethereum limiter, version 2.

Thankfully, the GPU shortages are behind us, and with RTX 40-series cards now starting to arrive, Nvidia and its partners have a glut of high-end RTX 30-series cards to sell. RTX 3080 Ti models often sell below $1,000, and short-term sales have seen prices as low as $700. With the RTX 4080 slated to launch on November 16, and likely an RTX 4070 or similar arriving by January that will at least match the performance of the RTX 3080 Ti, I wouldn't spend a ton of money on this sort of card right now.

Nvidia "unlaunched" the RTX 4080 12GB, but the AD104 GPU used in that card will almost certainly arrive in an RTX 4070 or 4070 Ti in the next couple of months. Such a card shouldn't cost much more than $599, and leaked benchmarks of the canceled RTX 4080 12GB suggest it would be at least as fast as the 3080 Ti — plus with support for DLSS3, improved ray tracing hardware, and with lots of L2 cache to mitigate the relatively narrow memory bus.
