Architectural Differences

  1. Clock Speed: Significantly faster clock speeds were observed on the RTX 4080 Super. The RTX 4080 Super has a base clock of 2295MHz and goes up to 2550MHz. Whereas the RX 6900 XT starts at 1825 MHZ and goes up to 2015 MHz.
  2. VRAMDespite releasing 3.5 years before the RTX 4080 Super, the RX 6900 XT matches the 16 GB VRAM offered by the RTX 4080 Super. This is embarrassing from a $999 graphics card in today’s age, but at least it’s faster GDDR6X RAM.
  3. TDPThe RTX 4080 Super will require a bigger PSU to run, as it has a slightly bigger TDP of 320 watts. Compared to that, the RX 6900 XT comes with a TDP of 300 watts.
  4. Process NodeThe RTX 4080 Super comes with the latest 5 nm process node launched by TSMC. Compared to that, the RX 6900 XT features a slightly older 7 nm process node by the same manufacturer. 
  5. Other Technologies: This is the aspect where Nvidia GPUs excel. The RTX 4080 Super comes with DLSS 3 and Frame generation which nearly double its performance. Compared to that, AMD’s GPU offers FSR as a replacement to that.

Nvidia has dropped a new thousand-dollar GPU in the market, the RTX 4080 Super. But how does that compete against a similarly priced GPU from the previous generation launched by their competitor AMD? Keep reading as we compare the RTX 4080 Super Vs RX 6900 XT and analyse their performance differences.

Editor`s Note
Image

In terms of gaming benchmarks, the RTX 4080 Super seems to crush it against the older RX 6900 XT. However, one thing we need to keep in mind is that the RX 6900 XT does not cost $999 anymore, and is now available for a fraction of its price. So does, the RTX 4080 Super justify its hefty price tag?

In terms of thermal efficiency, our observation states that the RTX 4080 Super runs 10% cooler as compared to the RX 6900 XT. The new 5 nm process node is easier to cool. Regardless of that, the difference is not small enough to fall within the margin of error, hence the RTX 4080 Super is the more thermal efficient GPU out of the two.

Difference0%66.7%

Both of these flagship GPUs were launched for $999 with a 0% difference in MSRP. However, since the RX 6900 XT has been out for a while, you can find it for much less than what it launched for. Our research indicates that you can find it for around $499 now. That puts RTX 4080 Super in a tricky position as it is 66% more expensive now.


What We Recommend

RX 6900 XT: If you are on a tight budget, and you want to squeeze the absolute most amount of gaming performance within the budget and want top performance for your dollar, we recommend you to check out RX 6900 XT. Its massive VRAM enables us to be able to play games at 2160p even after four years of its launch date. 

RTX 4080 Super: If you can afford to increase your budget, the RTX 4080 Super is recommended for you. It literally crushed the RX 6900 XT in almost every game we tested while also running cooler. That is before we even factor in DLSS 3, Frame generation and Ray Tracing performance, which make this GPU very hard to ignore.

After spending our time testing with these graphics cards, we can confirm that both of these GPUs are very capable in their respective price range. Which one is better suited for you would depend greatly on your budget, however, you can not go wrong with either of these GPUs.  


Frequently Asked Questions

Which one is better recommended for a warmer climate?

Our observation states that the RTX 4080 Super runs roughly 10% cooler as compared to the RX 6900 XT. So if you dwell in a warm climate zone, you should consider that.

Does RX 6900 XT have DLSS?

DLSS is limited to Nvidia GPUs. AMD features their FSR as an alternate with their GPUs to counter Nvidia’s DLSS.

Is 16 GB VRAM enough for today?

Both of our GPUs come with 16 GB VRAM and we tested around seven games at maxed-out 2160p resolution and both GPUs were able to provide a playable experience.
