  • RX 6950 XT uses RDNA 2.0 architecture, whereas the RTX 4080 uses ADA Lovelace architecture. Some of AMD’s latest cards use RDNA 3.0, so buying an RX 6950 XT may not be as future-proof.
  • While AMD RX 6950 XT has more RT Cores, ideal for ray tracing and specific AI workloads, the RTX 4080 has more Tensor Cores, which are suitable for AI, deep learning, and dedicated inference tasks.

Never before have we seen such a spectacular showdown between two revolutionary graphics cards. On one side, we have the RTX 4080 from NVIDIA; on the other, AMD’s RX 6950 XT. Both offer incredible performance and stunning visuals. Answering the question of which is the better buy can be tricky, but no matter how you slice it, one must come out on top.

AMD’s RX 6950 XT, built on 7 nm process technology, launched on May 10th, 2022, and was priced at a whopping $1,100. In November of the same year, NVIDIA launched the RTX 4080, built on 4 nm tech, for a hefty $1,200. The price difference can be negligible in some cases, but this can be a deciding factor for those on a budget.

So, to better decide which is the better buy, we took a closer look at their overall features and performance. We’ll discuss how these beasts perform in a few gaming scenarios and try to help you decide on the right buy, so buckle up! Let’s ride.

RTX 4080 vs RX 6950 XT: Overview

RTX 6950 XT was rushed to the party, no lie. We say so because AMD currently incorporates RDNA 3 architecture in its 2023 line of GPUs like the RX 7600M XT, whereas the 6950 XT still runs on RDNA 2. Despite being an outdated architecture, it brings innovative features like AMD’s infinity cache technology and ray tracing capabilities.

With the RDNA 3 architecture, you’d get AI acceleration, improved shading performance, and 2nd gen hardware-accelerated ray tracing capabilities. AMD had its reasons for the early launch, but we’d have seen a completely different product if it had waited.

NVIDIA’s RTX 4080, on the other hand, packs a mean punch with its Ada Lovelace architecture. AI-based neural graphics and ray tracing capabilities are no longer just a dream with this bad boy. You also get AV1 encoders, which are 40% more efficient and faster than H.264, and an AI-based DLSS 3 Ultra performance boost.

To match the software optimization effectiveness of the RTX 4080’s AI-based features, AMD RX 6950 XT must use hardware brute force. It’s not a bad thing per se, but we all know that software optimization beats hardware optimization any day, any time.

RTX 4080 vs RX 6950 XT: What’s the Difference

From the above table, it’s easy to notice that the RTX 4080 has better specs in most categories. But how do these paper stats translate to performance? Let’s find out.

Architectural Differences: Ada Lovelace vs. RDNA 2.0

The RTX 4080 runs on the latest Ada Lovelace architecture, whereas the RX 6950 XT uses a slightly older RDNA 2.0 architecture.

Ada Lovelace is built from the ground up for ray-tracing and AI. It supports real-time ray tracing, DLSS 3.0, and other features that make gaming more immersive and realistic. Packed with fourth-gen tensor and third-gen RT cores, this architecture will increase throughput, making it more than five times faster than the previous generation.

On the other hand, RDNA 2.0 touts enhanced compute units and first-gen ray-tracing accelerators. It also offers improved performance and efficiency over the previous RDNA 1.0 architecture. Enough of the technical mumbo jumbo – let’s talk about how these architectural differences affect gaming performance.

Although AMD has more RT cores (80) than NVIDIA (76), the RTX 4080 has 304 tensor cores, whereas the RX 6950 XT doesn’t. The role of tensor cores is to facilitate AI and machine learning processes. So when it comes to ray-tracing and AI, the RTX 4080 will outperform its AMD rival.

Ada Lovelace facilitates the use of Artificial Intelligence for DLSS3.0 upscaling. The results are more intuitive and realistic images, with none of the blurriness that can occur with lower-quality upscaling algorithms.

In a basic sense, it inserts more frames and smooths out image transitions, so gaming looks smooth and realistic. On the other hand, the hardware-oriented RDNA 2.0 architecture relies on the FSR 2.0 upscaling algorithm, which is good but not as advanced as DLSS3.0.

Memory and Bandwidth

The role of memory and bandwidth is to make sure that the GPU doesn’t bottleneck. For instance, if the GPU is processing data faster than the memory can keep it in the VRAM, there will be a bottleneck that wastes performance.

For a long time, NVIDIA has held the lead in terms of memory and bandwidth. The RTX 4080 comes with 16 GB GDDR6X VRAM, which offers 716GB/s of memory bandwidth, compared to the RX 6950 XT’s 16 GB GDDR6 VRAM and 576 GB/s bandwidth. The difference between GDDR6X and GDDR6 is that the former offers higher speeds and efficiency.

There’s no comparable difference between the memory capacity of both cards, but the RTX 4080’s higher bandwidth allows it to keep up with its faster memory. The bus width is the same across both cards: 256-bit. So it’s really the speed and efficiency of GDDR6X that gives the RTX 4080 an advantage.

Processing Size

If you’ve ever compared CPUs and GPUs, you’ll know that the size of the transistors matters. Smaller transistors mean better performance, less power consumption, and more efficiency. The RTX 4080 has 4 nm transistors compared to the RX 6950 XT’s 7nm. This difference may seem negligible, but it can significantly affect performance and power draw.

For instance, the RTX 4080’s 4 nm transistors will produce less heat than the RX 6950 XT’s 7 nm, which means you can overclock the card to higher levels without worrying about its temperature. RTX 4080 has 45,900 million transistors, while the 6950 XT has 26,800 million. Increased transistors mean more computational power, which translates to better performance.

Speed: Core, Boost, and Overclocking

A vital factor to consider when comparing two GPUs is their base and boost speeds. The RTX 4080 has a base clock of 2,205 MHz and a boost clock of 2,505 MHz. The RX 6950 XT runs at a 1,860 MHz base and 2,310 MHz boost.

In terms of raw speed, the RTX 4080 is ahead by a fair margin. It’s also worth noting that both cards have relatively ample overclocking headroom. If you’re willing to take the time and effort, you can push them close to their theoretical maximum speeds. Remember, though, that overclocking can be risky and should only be done if you’re confident in your abilities.

TDP

There’s also the matter of thermal design power (TDP). The RTX 4080 requires 320W, while the RX 6950 XT needs 335W. Now, this isn’t only about your electricity bills. It’s also about the cooling setup you’ll need to get the card running correctly. The lower TDP of the RTX 4080 means it will run cooler and quieter than its AMD counterpart.

Cuda Cores

Another critical factor when comparing GPUs is their CUDA core count. CUDA core counts help determine how many calculations the GPU can handle at once, ultimately affecting its performance. NVIDIA’s RTX 4080 has 9728 CUDA cores, while the RX 6950 XT stream processor count stands at 5120.

Interestingly, you’ll notice some unexpected differences in ray tracing cores. The RTX 4080 has 76 RT cores, compared to the RX 6950 XT’s 80. However, tensor cores are different, with the RTX 4080 holding the lead with 304 vs. the RX 6950 XT’s 0 cores. The RTX 4080 will perform better in tasks requiring ray tracing and AI, such as DLSS3.0.

Gaming Performance

So, how do these cards compare in gaming performance? You first need to realize that these are high-end GPUs, so any tests you run should be 4K resolution at ultra settings. You want to push the cards to their maximum capabilities and get an accurate representation of the performance.

Mark PC on YouTube benchmarked these two cards with different games, and the results are pretty interesting.

  1. God of War: When playing God of War at 4K Ultra 2160p, the RTX 4080 maintained an FPS above 100. The RX 6950 XT didn’t manage to keep up, but it still delivered playable FPS with drops below 78 FPS. Low 1% results were a bit more dramatic, with the RTX 4080 maintaining 93 FPS versus the RX 6950 XT’s 24 FPS.
  2. Cyberpunk 2077: Cyberpunk 2077 is a resource-intensive game on even the best GPUs, and these two cards are no exception. The RTX 4080 managed highs of 80 FPS and lows of 63 FPS. The RX 6950 XT couldn’t exceed 60 FPS but still delivered playable frame rates. Low 1% results were an average of 55 FPS for the RTX 4080 and 8 FPS for the RX 6950 XT.
  3. Assassins Creed Valhalla: Again, the RTX 4080 came out on top in this game. Highs were over 95 FPS with lows of about 84, and low 1% results were an average of 2 FPS. The RX 6950 XT couldn’t keep up, with highs of only 75 FPS and lows of 64. Low 1% results were an average of 2 FPS. Similar to the RTX 4080.

Overall, these two cards offer excellent gaming performance, but with a slightly different balance of power. The RTX 4080 maintains a higher average frame rate than the RX 6950 XT, but performance can vary depending on the title.
