AMD Radeon RX 6800 XT vs NVidia RTX 3080 (Updated 2022)

The old Team Red and Team Green dispute is back again this year!

The epic fight between AMD and Nvidia carries on, through the new video cards. We saw AMD release the RDNA2-based Radeon graphics cards – the RX 6000-series, and Nvidia taking their 2nd gen RTX architecture, the Ampere-powered RTX 30-series straight out of the oven.

While Nvidia had major stock issues with the RTX 30-series that were in greater demand than expected, AMD launched the RX 6800, RX 6800 XT and RX 6900 XT to match their rival.

When it comes to finding a GPU that offers the best performance per price ratio, two video cards come to mind: AMD Radeon RX 6800 XT and NVidia GeForce RTX 3080. But which model should you get and which one has an advantage?

Nvidia is known as the best performance GPU maker, but what if AMD is overthrowing that position with its Radeon RX 6800 XT? There’s only one way we can find out, so let’s compare these GPUs in terms of specs, benchmark test results, and pricing.

AMD Radeon RX 6800 XT vs NVidia RTX 3080 – Specs & Features

When it comes to memory, the two GPUs are not just different in terms of quantity, but also in terms of speeds. The AMD Radeon RX 6800 XT does come with 60% more VRAM than the GeForce RTX 3080, but the latter comes with a memory that has faster bandwidth speeds since it’s a GDDR6X memory.

Right now, games do not need more than 10 GB of VRAM, but in the future, they will undoubtedly be more demanding, which is where the GeForce RTX 3080 may struggle to keep up with the competition. Adobe Premiere can also benefit from more VRAM, and this is where the Radeon RX 6800 XT wins.

Looking at the memory bus, we see that the Radeon RX 6800 XT is smaller than the GeForce RTX 3080. However, AMD’s Infinity Cache adds an extra 128 MBs, closing the gap and even surpassing the competition.

Not even the GDDR6X VRAM type can save the GeForce RTX 3080 from this loss.

Looking at the shading units, cores and CUs, the Radeon RX 6800 XT is capable (in theory) of a performance of 41.47 TFLOPs, 20.74 TFLOPs, and 1.296 TFLOPs in FP16, FP32, and FP64 performance respectively, as seen in the spec sheet above.

Meanwhile, the GeForce RTX 3080 is equipped with 8,704 CUDA Cores, 272 TMUs, 96 ROPs, 68 RT cores, and 272 Tensor cores. This would yield a theoretical performance of 29.77 TFLOPs (FP16 and FP32) and 0.4651 TFLOPs (FP64).

We will talk about rendering power in the benchmark results and see how the two GPUs compare not just in theoretical scores, but also in tests.

In terms of power consumption, the Radeon RX 6800 XT performance (as marketed by AMD) surpasses the GeForce RTX 3080, and it should need more power. However, it needs even less power than its rival, and this also means it runs cooler. So, once again, AMD wins in terms of power efficiency as seen on the spec sheet.

Of course, each GPU comes with its own features. We see the RDNA2 architecture on the Radeon RX 6800 XT, along with Infinity Cache, new Ray Accelerators and AMD Smart Access Memory.

Nvidia also brings a new architecture and new features, including a different thermal performance for “for a quieter and cooler gaming system. ” Then, there’s DLSS AI Acceleration and Ray tracing.

Let’s see how these GPUs perform in different tests.

AMD Radeon RX 6800 XT vs NVidia RTX 3080 – Benchmarks

Nvidia revealed the performance of the NVidia RTX 3080 against the RTX 2080 and the GTX 1080. With RTX ON (RT + DLSS), at 4K, highest game settings, the RTX 3080 reached almost 80 FPS in Control and Minecraft. Meanwhile, at the same settings, it was able to reach 60 FPS. It’s safe to say that the RTX 3080 is a great upgrade over the RTX 2080, the latter offering nearly 50% less performance.

AMD also revealed benchmarks – more than what Nvidia shared so far about their GPUs. They put the RX 6800 XT against not only its predecessors but also against the competition. We chose the Borderlands benchmark from AMD to show you a comparison between the two tests.

We see the RX 6800 XT on the second spot, head to toe with the GeForce RTX 3090 and not with its direct competitor – the RTX 3080! Reaching nearly 66 FPS, the RX 6800 XT shames the GeForce RTX 3080, which can only reach around 58 FPS.

What we don’t know from AMD is whether the GeForce RTX 3080 had RTX on and DLSS or not. If AMD were to use Ray Tracing in these tests, numbers would look totally different. But enough with tests from AMD and Nvidia. Let’s see if what they’re bragging about is true.

RX 6800 XT vs NVidia RTX 3080 (Core i0-10900K) – Ultra Settings, 1920×1080, 2560×1440, 3440×1440

Looking at the test results in the list above, we see that both GPUs yield nearly the same results.

The RX 6800 XT delivers from 68 FPS to 131 FPS when playing Microsoft Flight Simulator, Assassin’s Creed Valhalla, Cyberpunk 2077, Red Dead Redemption 2 and other games at 1080p Full HD. At 1440p Quad HD, we ran the same games and saw an average of 62 FPS.

The RTX 3080 delivers from 67 FPS to 130 FPS when running the same games at the same settings. At 1440p Quad HD, we ran these games and saw an average of 63 FPS.

However, these tests don’t show us everything about what these GPUs can do.

For instance, AMD’s Rage Mode is a significant boost, offering overclocking with one touch of a button. Along with Smart Access Memory, the RX 6800 XT becomes up to 13% better than the RTX 3080 – but only in specific games (such as Forza Horizon 4).

Let’s not forget that Ray Tracing is also a sensitive subject when it comes to AMD’s performances. In synthetic benchmarks, we see the RX 6800 XT losing against not only its opponent but also against the RTX 2080 Ti.

In terms of Ray Tracing, Nvidia’s RTX 3080 has the upper hand when it comes to achieving better FPS, due to its dedicated RTX cores.

In addition, turning on DLSS will yield better performance at no cost to visual fidelity – sometimes even improving it. With DLSS turned on, the FPS grows by nearly 65% in some games.

On paper, looking at the test results, and using the default settings for each GPU, there’s no noticeable difference in terms of performance.

However, once you start using Nvidia’s DLSS and Ray Tracing features, the performance and visuals of the RTX 3080 significantly improve. Even though AMD tries catching up with their Rage Mode and Smart Access Memory feature, it’s still left behind. Moreover, Smart Access Memory will only work with AMD Ryzen 5000 CPUs.

We’re still waiting for AMD to finish their work on FidelityFX, which will be AMD’s answer to Nvidia’s DLSS. On the other hand, Nvidia is also working on their own version of Smart Access Memory, which will work with any next-gen CPU.

AMD Radeon RX 6800 XT vs NVidia RTX 3080 – Price

The RX 6800XT was launched at a $649 MSRP, while the GeForce RTX 3080 was launched at a $699 MSRP. For a $50 difference, Nvidia is the clear loser here if we were to look at the sheet provided by GPUcheck. The RX 6800XT has an overall score of 74/100, while the GeForce RTX 3080 has a score of 65/100.

AMD Radeon RX 6800 XT vs NVidia RTX 3080 – Verdict

Imagine being able to play Minecraft in 4K with ray tracing on and Nvidia DLSS at 93 FPS. Now use AMD’s Radeon RX 6800 XT at the same settings and try playing at barely 30 FPS. Even though AMD tries to keep up with other options such as adaptive sharpening and varying-rate shading, it cannot offer the same option as DLSS (yet).

The verdict is that although the overall performance is the same, Nvidia’s extra features are worth the extra cash. If we wanted to build a new gaming PC, we’d grab an NVidia RTX 3080 GPU without a second thought – but that’s mostly because we’d play games that use DLSS and Ray Tracing. Unfortunately, it isn’t easy to find an NVidia RTX 3080 on the market right now.

If you’re looking to buy a powerful video card that plays standard rendered 4K resolution games, both the NVidia GeForce RTX 3080 and the AMD Radeon RX 6800 XT offer great performances. In the end, two factors will influence your choice: availability and price.

The AMD Radeon RX 6800 and 6800 XT graphics cards went on sale on November 18 in very limited quantities. Even now it is very difficult to find them in retail at an adequate price. The recommended cost of the first is $579, and the second is $649.

They differ from each other in GPU configuration. The RX 6800 got the Navi 21 XL chip with support for 3840 stream processors instead of the 4608 in the Navi 21 XT. The GPU clock speeds of the RX 6800 XT are 145-200 MHz higher. This leads to an increase in performance and TDP. But the video memory subsystem in both cases consists of 16 GB GDDR6 with an effective frequency of 16 GHz and a 256-bit bus. Also available in 128 MB Infinity Cache.

In addition, the RX 6800 supports all the technologies that we talked about in the 6800 XT review. We will not go deep: for those who are interested, see the previous comparison with a more detailed description. Here we only briefly recall the key points.

First of all, this is a full implementation of the DirectX 12 Ultimate API, including Mesh Shading, Sampler Feedback, VRS and ray tracing. Hardware support for ray tracing is provided using special Ray Accelerator blocks and is accelerated by Infinity Cache.

AMD pioneered Smart Access Memory technology. Although it has existed for a long time in the form of the Re-Size BAR function of the PCIe interface, no one has shown interest in it before, and after the announcement of AMD by NVIDIA, Intel and motherboard manufacturers have actively taken up its adaptation.

AMD Anti-LAG technology in conjunction with Radeon Boost reduces Input Lag in games. It will be especially useful in competitive shooters and eSports disciplines. This is an analogue of NVIDIA Reflex.

AMD also has a set of FidelityFX technologies to improve the visual quality of games. Later, Super Resolution technology will appear in it — an analogue of NVIDIA DLSS.

Finally, let’s recall the support for HDMI 2.1 and USB Type-C interfaces, as well as hardware acceleration of the AV1 format.

We will get acquainted with the capabilities of the novelty using the example of the PowerColor Radeon RX 6800 Red Dragon OC video card. She received two BIOS chips with Silent and OC profiles. In the first case, the game and boost frequencies are 1905 and 2140 MHz, and in the second — 1950 / 2170 MHz. This is higher than the reference 1815/2105 MHz. We tested in OC mode.

This video card is not good for overclocking alone. She also received an 8 + 2-phase power subsystem with DrMOS chips and an efficient cooler. Its massive build includes a large copper base, a two-piece aluminum heatsink, seven 6mm heatpipes, a metal backplate, and three fans: two 100mm and one 90mm. They are based on reliable double ball bearings. Not without red LED-backlight and semi-passive mode thanks to Mute Fan technology.

For correct operation, the new product requires two 8-pin PCIe connectors. The set of external interfaces has one HDMI and three DisplayPort.

The following opponents participated in the comparison. Inside AMD’s lineup, we’ll take a look at the RX 6800 versus 6800 XT . The second is a reference model with a vapor chamber, an aluminum heatsink and three fans as part of the cooler.

The RX 6800 has no direct external competitor. It sits between the more expensive $699 RTX 3080 and the cheaper $499 RTX 3070. The first of these is represented by the INNO3D GeForce RTX 3080 iCHILL X4 model. It boasts a factory overclocked GPU dynamic frequency from 1710 to 1770 MHz. In games, the speed will be even higher due to the efficient cooler with 8 heat pipes and 4 fans.

The honor of the less expensive representative of Ampere will defend Palit GeForce RTX 3070 JetStream OC . It also received a factory overclocked GPU dynamic frequency from 1725 to 1815 MHz. That is, the RX 6800 and a couple of competitors are placed in the same conditions. And the novelty from Palit has a stylish design, addressable RGB lighting, two BIOS chips, DrMOS chips in the power circuits and an efficient cooler with 2 fans.

To complete the picture, we added the reference NVIDIA GeForce RTX 3060 Ti to the comparison. It is not a direct competitor — the difference in recommended prices is $180 or 45%. Is it worth it to pay extra or can you save money? The video card itself looks very stylish with a dual-fan cooling system. Unlike the older versions, the cooler has lost the evaporation chamber, but it is not needed in a 200-watt video card. The GPU and 8GB of GDDR6 memory run at reference clock speeds. For power, you need to connect a new 12-pin connector — that’s where the corresponding cable from Seasonic came in handy!

The comparison would not be complete without a member of the Turing family. The RTX 3070 competes with the RTX 2080 Ti in terms of performance, so the MSI GeForce RTX 2080 Ti GAMING X TRIO was added to the tests. Thanks to Telemart for it. This is a real flagship of the last generation with a factory overclocked GPU dynamic frequency up to 1755 MHz and a massive 3-fan TRI-FROZR cooler.

In synthetic we also added the results of PowerColor Red Devil Radeon RX 5700 XT OC and Palit GeForce RTX 2080 SUPER GameRock to evaluate the new product against the backdrop of a larger number of previous generation video cards.

Let’s take a quick look at the test bench. It is based on the once top 16-thread processor Core i9-9900K .

We did not manually overclock it, but used the bus function on the ASUS Prime Z390-A board.

3-section dropsy assigned to CPU temperature NZXT Kraken X73 with FDB bearings.

The 32 GB kit DDR4-3600 CORSAIR Dominator Platinum RGB solved all the problems with RAM.
