6700 XT vs 3080: Key Specifications

Architecture

Nvidia RTX 3080 2
Nvidia RTX 3080

The last few years saw both Nvidia and AMD take quantum leaps in technology — as Nvidia unveiled its Ampere architecture, AMD brought RDNA2 as its plus 1 for the party. Both Ampere and RDNA2 have done wonders for GPU capabilities, as can be seen on both the low-end as well as the upper end of cards both companies released based on these architectures. So you have the 6700 XT with RDNA2 and the RTX 3080 with Ampere. 

But what’s the big deal?

While RDNA2 introduced Infinity Cache and Smart Access Memory (SAM) as a key feature, Ampere brought us Deep Learning Super Sampling (DLSS). And if you were wondering what they are, Infinity Cache efficiently accesses more of your onboard memory, allowing SAM to dig into all of your GPU VRAM, which was not possible earlier because of a 256MB limit. 

What does that mean for you as a gamer? According to AMD, anything between a 5% to 15% bump in performance. 

Not many people may be aware that Nvidia, too, utilizes the same tech, called Resizable BAR. The company announced Resizable BAR support for 3060 GPUs and RTX 3000 series graphics cards in 2021, clearly after AMD inspired it to do so. 

But let’s talk about DLSS now, shall we? 

It is a type of rendering that uses AI to first render frames at a lower resolution, then upscale the frames in the output so that they look sharp and detailed. In short, it could render the frames of a game at 1080p and then blast you with 4K output thanks to AI, but with a lot less computational power, which means excellent FPS and crisp details.

This round is a draw.

Clock Speeds and Overclocking

The clock speed is the speed at which your video card operates. From the table above, you can see that the 6700 XT has a base clock of 2321 MHz, while the 3080 runs at 1440 MHz. This is what you get off the shelf. 

And if you wish to overclock your GPU so that you can get some more juice out of them at the cost of more power, that is possible as well. But note that overclocking can be tricky — you really should know what you’re doing, and you’re supposed to overclock in a staggered manner so that you don’t brick your card.

And once you’re ready, you should know that the 6700 XT allows you to dial it up all the way to 2581 MHz, while the 3080 lets you push it to 1710 MHz. 

You can read stories online where some users have gone beyond, but it could be a case-by-case thing, so we don’t really recommend that you do the same. After all, you still have to deal with the bump in power and heat, so don’t take this lightly!

This round is a draw as well!

Cores

Cores! What cores? Well, cores are the heart of your GPU and are the muscle responsible for the calculations needed for graphics; while AMD calls them stream processors, Nvidia likes to call them CUDA (Compute Unified Device Architecture) cores, sounding like something you’d see in a Star Wars movie. So the 6700 XT has 2560 stream processors while the 3080 packs 8704 CUDA cores, and yes, that does make the 3080 superior to the 6700 XT. 

The RTX 3080 wins.

Shaders, Ray Tracing cores, and TMUs

RT cores on the 3080 are your Ray Tracing Cores, and they are the reason that gaming visuals look so great these days. The 6700 XT offers ray tracing, too, thanks to its compute units. But the 3080 has 68 RT cores, whereas the 6700 XT has 40 compute units.

Shaders tackle the shadows, lighting, and shading aspects of gaming graphics, whereas TMUs or texture mapping units work on 3D mapping from bitmaps. Both of these components play a critical role in ensuring you get the best graphics at the best frames per second. 

In this comparison, the 3080 wins with their TMU and shader count, too — it has 272 TMUs (or, as Nvidia also calls them, Tensor cores) and 8704 shaders. In comparison, the 6700 XT has 160 TMUs and 2560 shading units.

The winner here is the RTX 3080.

VRAM and Memory Specs

The 6700 XT flexes hard with its 12GB of DDR6 RAM, punching well above its weight class. Which makes a lot of sense when you consider how important Smart Access Memory is to AMD cards in general. 

The RTX 3080 is considered a premium card and, unfortunately, only packs 10GB of VRAM, which is a bit annoying and makes you wonder if the card is ready for the games that will release over the next few years.

We give this round to the 6700 XT because we’d like to send a message to Nvidia!

Performance and Resolutions

When it comes to performance and resolution, the RTX 3080 is clearly the superior card. The 3080 is more of a 4K gaming beast and is much more expensive than the 6700 XT. If you wanted an AMD card that could take on the likes of the 3080, you’re best off considering the 6800 XT instead, which makes this a good moment to plug our 6800 XT vs 3080 comparison article!

Be it benchmark tests or FPS during heavy games, the RTX 3080 consistently outperforms the 6700 XT when it comes to both resolution and performance. If 4K gaming at 60fps was your dream, the 3080 is here to make that dream come true.

The 3080 dominates this round.

Connectivity

The 6700 XT has a single HDMI 2.1 and three 1.4a DisplayPorts, and it is the exact same story for the RTX 3080. As for power connectors, the 3080 uses a single 12-pin connector, whereas the dual-slot 6700 XT uses a 6-pin + 8-pin connector combo (good time to remind you not to use split power cables for your video cards!). 

An annoying bit of news about both these cards is that they both lack USB ports. You do still have four peripheral ports. We consider this round a tie.

TDP

TDP, or Thermal Design Power (also called Thermal Design Point), is the maximum power your card is permitted to pull from your power supply unit. On the 6700 XT, this number is at 230W, whereas it’s a whopping 320W for the 3080. But don’t get confused about the power rating for your PSU because you need headroom as well. We recommend a 550W PSU for your system if you get a 6700 XT and a 700W PSU if you get an RTX 3080.

And if you’re feeling the heat from the price tag on the RTX 3080, we would like to recommend that you take a look at the RTX 3070 Ti. Here’s a comparison of the 3070 Ti vs RTX 3080 to clear things up!

Conclusion

Well, we could have told you this at the start, but we had to go into detail to justify our reasons in this 6700 XT vs 3080 comparison — the 3080 is the clear winner, purely from an output perspective. It is significantly more expensive because it can do much more than the 6700 XT can. That said, the RTX 3080 can be overkill for many gamers — so if you’re a casual gamer looking for a good time, the 6700 XT delivers the goods.
