Pros And Cons

Comparison Table

Architectural Differences

1. Clock Speed: The RTX 4080 Super has faster clock speeds, running at 2295 MHz and up to 2550 MHz. The RX 7800 XT, on the other hand, has a base clock of 1295 MHz that goes up to the boost clock of 2124 MHz.
2. VRAM: Both GPUs come with 16 GB VRAM. The RTX 4080 Super has a superior VRAM buffer of 16GB of GDDR6X memory. The RX 7800 XT relies on a slightly slower GDDR6 memory. Both GPUs share the same 256-bit memory bus.
3. TDP: AMD takes the point here, as they managed to release RX 7800 XT with a remarkably low TDP of 262 watts compared to the RTX 4080 Super which comes with a much bigger TDP of 320 watts. 
4. Process Node: Another spec that both of our competing graphics cards seem to share with each other is the process node. Both graphics cards come with the 5 nm process node made by TSMC.
5. Other Technologies: This is the aspect where Nvidia shines the brightest. Both GPUs come with their own version of AI upscaling like AMD’s FSR and Nvidia’s DLSS 3 and Frame generation. However, the RTX 4080 Super has both.

Both Nvidia and AMD had price cuts in their last line of GPUs. So the situation redeemed us fit to get our hands on two of the newly released GPUs by both these manufacturers and let them lock horns against each other in a comparison to see which one emerges victorious. The GPUs in the equation are RTX 4080 Super Vs RX 7800 XT.

Gaming Tests – 2160p

To ensure fair competition, we have tailored this testing rig specifically for this comparison to ensure there are zero bottlenecks and most of the load falls directly on the graphics cards. This will enable us to closely monitor the performance difference of both GPUs without leaving any performance on the table.

• Power Supply: ENERMAX REVOLUTION D.F. X 1050W

Cyberpunk 2077

• Cyberpunk 2077 at maxed out 4k settings is no joke. However, both our competitors manage to provide a playable experience. The RTX 4080 Super provided 76 fps on average, whereas the RX 7800 XT provided 52.  
• The performance difference among both cards is staggering, as the 1% lows of the RTX 4080 Super are ahead of the average fps of the RX 7800 XT. The RTX 4080 Super provided 60 fps compared to the 45 fps of the RX 7800 XT. 

Watch Dogs Legion

• Watch Dogs Legion was a breath of fresh air for our GPUs, who were still recovering from the damage caused by Cyberpunk. The game ran at 111 fps at the RTX 4080 Super and 33% slower at the RX 7800 XT which was at 80 fps. 
• We observed a similar degree of separation between both GPUs in terms of 1% lows as well, at around 36% in favor of RTX 4080 Super. This time it was flying high at 97 fps, whereas its competitor could not go beyond 67 fps. 

Horizon Zero Dawn

• Horizon Zero Dawn ran smoothly on our graphics cards as both of them are now hitting triple digits. The RTX 4080 Super was at 132 fps. Compared to that, the RX 7800 XT was around 25% behind, yielding an average of 102 fps. 
• The difference observed in 1% lows was smaller this time, as the RTX 4080 Super retains its lead by 20%. The 1% lows provided by the RTX 4080 Super were at 92 fps while the RX 7800 XT was around 75 fps. 

Assassin’s Creed Valhalla

• Assassin’s Creed Valhalla ended up seeing a bigger difference than what we anticipated, even though the game runs better on AMD GPUs. The RTX 4080 Super was 32% ahead, giving 113 fps on average compared to 82 by the latter. 
• 1% lows had a similar tale to tell, as the RTX 4080 Super is 33% ahead here. On average, it provided 98 1% low fps in comparison to the 70 fps provided by the RX 7800 XT. 

Doom Eternal

• Doom Eternal is the easiest game to run in our benchmark, as both GPUs provide a high refresh rate experience. The RTX 4080 Super crushes the game at around 246 fps. The RX 7800 XT also provides a decent average of 184 fps. 
• The 1% lows were not very different from what we previously saw. The RTX 4080 Super was at 212 fps. The RX 7800 XT, at the same time, was 24% behind at 166 fps. 

A Plague Tale Requiem

• A Plague Tale Requiem brought our GPUs to their knees as we saw a t drop in their average fps. The RTX 4080 Super manages to run at 72 fps on average. The RX 7800 XT was seen struggling as it maxed out at 50 fps. 
• The game ran significantly smoother on RTX 4080 Super, as it was 30% ahead in terms of 1% lows. The 1% lows observed on the RTX 4080 Super were around 64 fps while the RX 7800 XT hovered around 47 fps. 

Red Dead Redemption 2

• Red Dead Redemption 2 was easier on both of our GPUs compared to the last title. The RTX 4080 Super yielded us a solid 118 fps experience. The RX 7800 XT, at the same time, was around 21% behind at an average of 95 fps. 
• The 1% lows saw an 18% difference in favor of the RTX 4080 Super. This time around, it provided an average of 91 1% low fps. In comparison to that, the RX 7800 XT maxed out at 76 fps. 

Overall Gaming Performance

As per our observation, the RTX 4080 Super totally wiped the floor with RX 7800 XT during our gaming benchmark. In terms of average fps, it was 30% ahead, of the average data of seven games at 2160p resolution. As for the 1% lows, things are not different here either, as the RX 7800 XT is still behind by a margin of 26%.

Editor`s Note

So far, the RTX 4080 Super does appear to be a much better GPU in almost every workload. However, performance is not the only aspect you consider when it comes to buying a new GPU. It also costs significantly more than its competitor and not a lot of people would be willing to bear that price tag.

Thermal Efficiency

Speaking of thermal efficiency, our analysis states that the RTX 4080 Super ran roughly 12% cooler than the RX 7800 XT. This could be due to its beefier heatsink. Either way, it is the more thermal efficient out of the two and if temperatures are of a concern for you, then you should definitely be looking into this. 

Price And Value

At launch price, the RTX 4080 Super is roughly 66% more expensive than the RX 7800 XT. Since both these GPUs are fairly new, you are unlikely to find them for lower than their MSRP. This makes the case a bit tricky for the RTX 4080 Super, as it is not easy to justify that hefty thousand-dollar price tag. 

What We Recommend

RX 7800 XT: Despite being dominated in almost every benchmark we conducted today, it is easier for us to recommend the RX 7800 XT because of its price tag and value. It performs 30% worse in games, but it is also 66% cheaper. That easily makes it the better bang for the buck. 

RTX 4080 Super: Unlike its competitor, the RTX 4080 Super is a premium flagship card and you have to pay a premium for it as well. It costs significantly more but you can’t ignore its merits. It has dominated every single one of our benchmarks, while also running cooler. This is before we even factor in DLSS and Frame generation.

Both RTX 4080 Super and RX 7800 XT are very capable GPUs and you can not go wrong with either of them. However, they are both launched for different consumers with different budgets. Whether you should go for Team Red or Team Green will depend greatly on your use case and how much you are willing to spend.
