The NVIDIA GeForce RTX 3080 Ti graphics card has been waiting for a long time, although it is basically just a slightly twisted RTX 3090 with half the memory capacity. NVIDIA could launch one on the market much earlier, if it wanted to. It was wanted only now, although of course the situation on the market and in production also contributed to this.

Yesterday we were able to see that the RTX 3080 Ti is only slightly weaker than the RTX 3090, whose performance can be easily caught up with increased beats. And so on Tom’s Hardware in the test, it states that it is “essentially a 3090 with half the VRAM and a weaker heatsink.” However, this applies to the Founders Edition.-

With a weaker heatsink because the card’s design is the same on the outside as in the case of the RTX 3080 Founders Edition, while the RTX 3090 is noticeably larger and thus has a more powerful heatsink. The heatsink from the RTX 3080 card must cool an additional 30 W on the Ti model, however, this of course only applies to cards from NVIDIA and AIB manufacturers can arrange otherwise.

The results of the game tests show that NVIDIA was able to beat the competing Radeon RX 6900 XT as expected, although with a card that is 200 USD more expensive. However, official prices mean almost nothing today, although some stores such as Best Buy try to keep them. But then there are scalpers again, who buy almost everything and the cards still reach end customers at significantly higher prices.

Very similar game test results are also shown by the Hexus server, which also tested the Founders Edition, except for the performance of the original RTX 3080 FE in relation to Radeons, but this will be greatly influenced by the choice of games.
In short, the NVIDIA GeForce RTX 3080 Ti is really just a little weaker RTX 3090 with half the capacity of VRAM. Thanks to overclocking, many non-reference versions could catch up and overtake the RTX 3090 FE, so players will be clear if they get to their chosen card.
