RX 6900 XT vs RTX 3080 – High End Battle

Latest update:

With the 3090 being such an expensive option, we’re looking at the cards that follow comparing the 6900 XT and the 3080. A fan-favorite duo that costs less but likely plenty of performance for all games and resolutions.

They both came out with their own streak, and they were the staple of formations for most people. Competing for the title of best graphics card, it offers a great choice from both AMD and Nvidia. We take a closer look at the best option for you.

building

Being from different GPU manufacturers, there is a lot of difference between how they are made. The AMD card is built based on the RDNA 2.0 architecture and in particular, the 6900 XT uses a NAVI 21 XTX GPU. It is built with TSMCs 7nm process making the mold 520mm2. While it also consists of 26.8 billion transistors.

On the other hand, Nvidia owns the Ampere die architecture. The 3080 is built using a proprietary GA102 GPU that is manufactured using Samsung’s 8nm process. 628mm mold packing2 With 28.3 billion transistors. Which gives it a much larger dice than the 6900 XT because it compensates for the larger transistors and fits better.

Comparing the 6900 XT and the 3080, we take a look at the components of graphics cards. At the most basic level, they have different architectures and so looking at their specifications may not be a one-to-one comparison. But it does give us a good idea, so we’ll look at some specific specs.

TDP

First, we take a look at the power of the thermal design of the two GPUs. This number tells us how much energy the die can consume at maximum power. This also tells us how much heat the card will produce. A factor to consider when considering overclocking, cooling your GPU, or the cost of running it.

Comparing these two cards, we find that it is a 6900 XT with a lower TDP. It maxes out at 300 watts, 20 watts below the 3080. Demonstrating that it will stay cooler and use less power to achieve its performance is probably a big factor when considering which one to choose.

VRAM

The GPU’s video memory is the frame buffer between the card and the CPU as well as the storage of texture maps. An important feature when considering the large resolution and multiple screens. Because it reduces latency and buffering with the ever-increasing demand for the number of pixels.

Comparing the 6900 XT and the 3080, there is a difference in both types of memory and size. AMD goes for the number of sizes rather than speeds. The 6900 XT has 16GB of GDDR6 VRAM, very large capacity but with a clock rate of 17Gbps and bandwidth of 512GB/s.

Whereas, Nvidia chooses the speed. The 3080 has 10GB of GDDR6X, which has a clock rate of 19Gbps, putting bandwidth at 760.3GB/s. Both may have different effects on performance.

hour rate

The clock speed of the card is determined by the speed at which the silicon crystal can register. This rotation handles the graphical instructions that output the graphical quality you need. While it’s not a straightforward display of performance, it can be a good indicator. Especially when you are trying to get the most out of the GPU with overclocking.

Again as we saw earlier, AMD is gaining an edge in clock speed over Nvidia. The 6900 XT is factory set to a base clock of 1826MHz and a boost clock of 2250MHz. Compared to base 3080s 1440MHz and 1710MHz. Offer a slight advantage to the red team.

GPU die cores

Cores are the various processing units within a GPU. They have different majors, and at our closer look, we have shaders, RTs, and TMUs. These focus on rendering and shading scenes, real-time ray tracing, and creating 3D textures from bitmap images.

Comparing the 6900 XT versus the 3080, the RTX card benefits from the number of shaders but loses in RT cores and TMUs. Possibly degraded performance in some areas.

RX 6900 XT Performance vs. RTX 3080

By taking a look at 3dmark benchmarks we can see the live graphic performance of graphics cards. And it is the 6900 XT that leads in this position, in fact, taking first place in the benchmark with a score of 20,352 points. While 3080 ranks only eighth with a score of 17,650.

In other scenarios though it’s a pretty close call. With 3080 effective speed slightly higher. But in games, they tend to trade blows with the performance being very similar. However, ray tracing is where Nvidia still takes the crown and gives the 3,080 an advantage in those scenarios.

price comparison

The launch price for the 6900 XT is $999, but the 3080 is much cheaper at $699. Which is a big difference at $300. The 43% price difference could be a huge turnaround from choosing an AMD card, especially with the performance similar.

However, in the current pricey GPU market, you are unlikely to be able to purchase a graphics card at MSRP. Checking these two, we find that PCPartPicker offers a cheaper 3080 at $1,798, compared to the 6900 XT at $1,260. Much cheaper for an AMD card.

Conclusion

Comparing the 6900 XT versus the 3080 on the MSRP, it’s hard to justify the 6900 XT in terms of performance. With a similar FPS but a loss in ray tracing, it doesn’t make sense, especially with Nvidias software solutions. However, in the current market, an AMD card is cheaper, so it might be better to afford it at that time. Although, time may be your friend, with current GPU prices dropping and the new RTX 4000 series near.
