Nvidia GeForce RTX 4080 Review

It’s time to examine the new Nvidia GeForce RTX 4080, Nvidia’s $1,200 GPU representing a significant 71% price increase over the RTX 3080. Of course, Nvidia would like that we ignore the RTX 3080 entirely and instead concentrate on the $1,200 3080 Ti.

While the industry has undoubtedly altered since then, it will be intriguing to see what the RTX 4080 offers. There are many topics to cover and benchmarks to look at, but before we do that, let’s talk about the specs, look at the Nvidia Founders Edition model, and then go on to the blue bar graphs. We also acquired partner models from PNY, Asus, and MSI in time for this review, which we will highlight at the conclusion.


  • GPU with the second-fastest speed (for now)
  • A top-notch ray tracing performance
  • It contains all of the Ada Lovelace upgrades


  • Over-priced
  • Needs DLSS 3 for true gaming performance
  • Persistent worries about the 16-pin connection

The Nvidia GeForce RTX 4080 is the follow-up to the RTX 4090, released last month, and is now one of the greatest graphics cards and is ranked first in our hierarchy of GPU benchmarks. Of course, the melting 16-pin connections have taken a little bit of the shine off. The good news is that since the RTX 4080 consumes less power, it should be less likely to channel enough power to melt the plastic connection. The bad news is that it inherits the RTX 3080 Ti launch price, which we also thought was too excessive, and is still too expensive for most gamers at $1,199. It also marks a significant generational price rise.

The GeForce RTX 4080 is built on the 378.6 mm2 AD103 silicon, which is 38% smaller than the AD102 silicon used by the RTX 4090 and has 40% fewer transistors. However, the 4080 still has 62% more transistors than the 3090 Ti flagship of the previous generation. Given those numbers, it shouldn’t be surprising that the 4080 has 41% fewer CUDA cores than the 4090, a 33% narrower memory bus, and 11% less L2 cache.

As for core clocks, there isn’t much of a difference between the RTX 4090 and 4080; boost clocks are 2505 MHz versus 2520 MHz, with the 4090 having a slight advantage. The RTX 4080 receives faster 22.4 Gbps GDDR6X memory, a 7% improvement over the series flagship, but the overall memory bandwidth has been reduced by 29% to 717 GB/s due to the smaller 256-bit wide memory bus.

Inside RTX 4080

How is the RTX 4080 constructed?

The AD103 chip, a second-tier Ada Lovelace GPU, is used in this RTX 4080 16GB card. The AD104, a third-tier GPU that should practically only be used in an RTX 4070-series card and not a modified RTX 4080, was chosen as the GPU for the 12GB card. Which, I suppose, is where we’ll see it reappearing next, with or without the “Ti” suffix.

The RTX 4080’s AD103 GPU, though, has all the architectural awesomeness that made the RTX 4090 such a potent new chip, regardless of how the AD104 stuff works out in the end. In addition to the frame-generating magic of DLSS 3, you also receive the fourth-generation Tensor Core and the third-generation RT Core. Naturally, this somewhat smaller piece of silicon.

Nvidia has chosen to utilize the same MASSIVE cooler used for the RTX 4090 Founders Edition, despite the GPU in the RTX 3060 Ti being smaller than the Ampere chip at its core. I have a PNY RTX 4080 that is the size of a tiny moon; the add-in board partners (AIBs) have also adopted this strategy.

Additionally, it uses a PCB that is quite similar to the RTX 4090 Founder Edition, a modified PG136. To handle the 320W Total Graphics Power (TGP) that the RTX 4080 generates, the board must have the same cutoff and be highly power-phased.

It has a common 16-pin power connector as well, but the supplied adapter is a triple-headed one rather than a quad-headed one like the RTX 4090’s. Although it’s not good for a very expensive, powerful graphics card, the cause of the melting 16-pin adapters in the wild is still unknown, Nvidia is continuing to work on the issue. Also, AIBs are.

Does this mean that, compared to the RTX 4090, the Nvidia GeForce RTX 4080 has a higher sweet spot for non-4K gaming? Maybe, but if you’re purchasing any RTX 40-series card to play games at 1080p, I’d suggest something isn’t quite right regarding your sense of appropriateness or value. When it comes to sub-4K resolutions, where you may still be constrained by the capabilities of your CPU, the RTX 4080 is virtually on par with the top-tier Ada card.
The updated drivers have given it additional performance in games where the 1080p and 1440p scores had previously been almost comparable. As a result, I was first shocked to find the RTX 4080 overtaking the RTX 4090 in several CPU-bound titles. Since then, with the most recent software, I’ve tested the Ada monster again on those games, and the tide has absolutely lifted all the silicon boats in the sea. I saw a 12% and 16% improvement in 1080p performance in Far Cry 6 and F1 22, respectively.

All of that is against the top-tier RTX 40-series card, but what about the RTX 3080 Ti, the $1,200 GPU it apparently replaces? The RTX 4080 outperforms the Ampere card by about 38% on average across all of our benchmarking software. That’s a significant performance improvement at the same cost.

Is an RTX 4080 a good investment?

When all other factors are taken into account, the fact that Nvidia can remove such a large portion of the GPU’s best features from its AD103 silicon while still performing at a level that is only a third lower than the much larger AD102 core indicates that it provides what you would want from the RTX 4080. Although the shroud is unreasonably large, it is quick, the GPU is surprisingly compact, and I am absolutely in love with DLSS with Frame Generation.

Nvidia has a history of determining card prices solely based on performance rather than the actual silicon used. The company has improved performance and efficiency going back to the Kepler architecture and the GTX 680(opens in new tab), and as a result, priced lower spec GPUs higher nominally.
