If you are thinking of buying a high-end graphics card and you are interested in having dedicated ray tracing hardware, surely you have considered some of these two graphics cards. For this reason, today we are going to make a technical comparison of the RTX 2080 Ti vs RTX 2080 graphics not to see which is better because that is evident, but to see whether or not it is worth paying the price difference between the two.
Although the starting price of the RTX 2080 was $ 699 and the RTX 2080 Ti was $ 999 , they have always had substantially higher prices in the European market and, currently, the RTX 2080 Ti are priced around 500 euros higher. to the RTX 2080, more than enough reason to consider whether or not the increase in performance they are going to provide is worth it.
Here you can see an example with these two graphics of the Zotac assembler in its AMP model, whose price difference is about 485 euros.
It is clear that the Ti version is vastly superior to the normal version, but how much for this price difference?

Technically, the RTX 2080 Ti is far superior to the RTX 2080: it has 5 million more transistors in a much larger area die, with 22 more CUs that represent no less than 1408 Shaders, 88 TMUs and 24 more ROPs, so its Gross computing power hits a huge jump of 3.38 TFLOPs .
As for the dedicated hardware for ray tracing, the ratio is logically the same and the RTX 2080 Ti wins by a lot. In total, it has 22 RT cores and 176 more Tensor Cores, so the performance on RTX will be much higher .
All this is increased by the graphic memory, and not only because the RTX 2080 Ti has 3 GB more of gross quantity, but also because although both graphics use GDDR6 memory, the bus of this GPU is wider and allows a bandwidth. far superior, in total 168 GB / s more than the RTX 2080.
All these improvements have a “price”, and it is that logically the Ti version has a 35W higher consumption , and since both have the same heatsink (we are talking about the reference models, of course) NVIDIA had to relax the operating frequencies of the RTX 2080 Ti compared to RTX 2080 so that the temperature would not shoot up, among other things.
This means that in the custom models of the assemblers who have equipped a better heatsink in this graph they will have much more room for Overclock than in the RTX 2080, but of course, always with an eye on the temperature since with its consumption it can reach be an inconvenience .
As for the heatsink , as we said both reference graphs use the same and, in fact, in most custom models it is also like this. For a couple of generations, NVIDIA has modified its graphics heatsink for a much more efficient one, both in terms of preserving operating temperature and noise, and it really is quite good and more than enough to keep graphics running at good temperature.
Finally, regarding the video outputs, both graphics incorporate exactly the same: 1 HDMI, 3 DisplayPort and a USB-C .
What performance do these graphics cards offer?
Both graphics cards are designed to offer excellent performance in any type of game and with all the graphic adjustments to the maximum, including 4K resolution. However, as you know, current triple A games with everything at maximum and 4K resolution are still too demanding and not even a RTX 2080 Ti can maintain 60 FPS stable in almost none of them.
All in all and with that, here is the average relative performance of these charts.
Obviously the RTX 2080 Ti gives us better performance in all cases.
Is it worth paying the price increase of the 2080 Ti?
If we extrapolate the average FPS that we obtain with each of these graphics cards and relate it to their price, we can get a very interesting fact, the FPS per dollar (based on launch prices). Thus, at 4K resolution the RTX 2080 Ti gives us 0.075 FPS per dollar compared to 0.095 FPS per dollar of the RTX 2080, while at QHD resolution these figures go to 0.105 on the RTX 2080 Ti and 0.137 on the RTX 2080.
This means that speaking of a direct relation of performance for price the best option is the RTX 2080 , although not by too much difference, everything is said. However, of course, if you do not have a budget limit and what you are looking for is the best performance whatever the situation, then your option should be the RTX 2080 Ti , as performance is undoubtedly the best option. available.
