Architectural Differences

  1. Core Clocks: Though the RTX 4080 has a significantly lower number of cores than its competition, it makes up for it with a frequency of anywhere from 2205MHz to 2505MHz. The RTX 3080 Ti, however, clocks in at a frequency of 1370MHz to 1667MHz.
  2. Process Nodes: The RTX 3080 Ti uses a fairly modern 8nm manufacturing process, whereas the RTX 4080 one-ups it with its 4nm lithography, allowing for great efficiency. 
  3. TDP: The RTX 3080 Ti has a rather high TDP of 350 watts, whereas the RTX 4080 improves on this with a slightly lower TDP of 320 watts. The actual power consumption of these cards can fluctuate quite a bit, which we will see in the power consumption section of this comparison.
  4. Memory: The VRAM capacity on the RTX 3080 Ti is 12GB, while the RTX 4080 improves on this again with a capacity of 16GB. Both use GDDR6X memory, but the older GPU has a wider bus.
  5. Other Features: Both cards are more or less matched in terms of features, except for one. The RTX 4080 can utilize AI to interpolate frames between traditionally generated frames to improve its framerate using Nvidia DLSS 3. Sadly, this feature does not make its way to the older card.

Average temperatures of the two graphics cards

The RTX 4080 showed no weakness in its thermal management either, averaging a peak temperature of around 76°C in our testing, while the RTX 3080 Ti averaged a peak of around 79°C.

Many factors can affect the thermal performance of your graphics cards, so you might experience totally different numbers than what we’re seeing here if you choose to purchase either.

Price and Availability

You can buy an RTX 4080 for around $1199 in most configurations, while the price might vary from variant to variant. The RTX 3080 Ti, however, comes in at around $1000 for new cards, according to PC part picker, though it can also very easily reach the price of the RTX 4080.

Both cards are very popular and should be accessible at any nearby computer parts store.

RTX 4080 Vs RTX 3080 Ti: What We Recommend

Now that we’ve seen the ins and outs of both cards, this part of the comparison will deal with the decision between the two graphics cards.

Despite what we expected, the RTX 4080 turned out to be a great upgrade to the last generation of high-end graphics cards, despite coming in at pricing expected from the tier above. Unless you are buying used, the performance uplift of the RTX 4080 justifies its cost, at least in the GPU market as of writing this comparison.

If you buy used, the RTX 3080 Ti can give you amazing bang for the buck, but the price of the card in unused condition has yet to come down to being reasonable enough to buy.
