AMD Radeon Pro 580X vs NVIDIA GeForce RTX 4080 SUPER Comparison

Head-to-Head Benchmarks

The database contains two shared benchmark results for these cards, and both paint a stark picture. In Geekbench OpenCL, the NVIDIA GeForce RTX 4080 SUPER scores 219,065 against the AMD Radeon Pro 580X's 36,426. That is a 501.4% advantage for the NVIDIA card. The gap is even wider in Geekbench Vulkan, where the RTX 4080 SUPER hits 260,075 while the Radeon Pro 580X manages 40,115, a 548.3% lead. These are not close contests by any measure; the results indicate the RTX 4080 SUPER is in a completely different performance tier.

Looking at the average benchmark score across all recorded tests, the RTX 4080 SUPER posts 54,209, whereas the Radeon Pro 580X averages 38,706. The database's nearest rival comparisons put the RTX 4080 SUPER at the 86th percentile of all GPUs, while the Radeon Pro 580X sits at the 82nd percentile. The percentile gap is modest, but the raw score difference is substantial because the benchmark pools differ. The RTX 4080 SUPER has ten recorded benchmark entries, including PassMark DirectX 9, 10, 11, 12, G2D, G3D, and GPU Compute tests. The Radeon Pro 580X has only three entries: Geekbench Metal, OpenCL, and Vulkan.

In the head-to-head tests, the RTX 4080 SUPER wins 2 out of 2 matchups. The Radeon Pro 580X does not win a single shared benchmark. For context, the RTX 4080 SUPER's nearest rivals in the database are the RTX 4080 (0.1% lower average score), the Radeon Pro W5700X (1.1% higher), the RX 6750 GRE 12 GB (2.7% higher), and the Radeon 8060S (2.8% higher). The Radeon Pro 580X's nearest rivals are the MX570 A (equal score), the RTX 5080 Mobile (0.9% higher), the MX570 (1.1% higher), and the Radeon Pro 575X (1% lower). The data shows the RTX 4080 SUPER competes with modern high-end desktop parts, while the Radeon Pro 580X sits alongside entry-level mobile and older workstation parts.

Where Each One Wins

The RTX 4080 SUPER wins every category where both cards have recorded data. In compute workloads using the OpenCL API, its 219,065 score dwarfs the 36,426 of the Radeon Pro 580X. Vulkan performance follows the same pattern: 260,075 versus 40,115. The RTX 4080 SUPER also has a much broader test footprint, with PassMark scores across DirectX 9 (381), DirectX 10 (193), DirectX 11 (301), DirectX 12 (134), G2D (1270), G3D (34245), and GPU Compute (19822). These additional benchmarks show strengths in legacy DirectX titles, 2D desktop acceleration, and general compute workloads.

The Radeon Pro 580X has one unique benchmark result not shared with the RTX 4080 SUPER: Geekbench Metal, where it scores 39,577. This is relevant for macOS applications that leverage the Metal API, and it is the only area where the Radeon Pro 580X has a recorded advantage by virtue of having a result at all. However, the RTX 4080 SUPER does not have a Metal benchmark in the database, so no direct comparison is possible. The Radeon Pro 580X also has a lower TDP at 185 W versus 320 W, and it uses an Apple MPX bus interface with an IGP slot width, which suggests it is designed for specific Mac Pro configurations rather than general PC builds.

For raw gaming performance, the RTX 4080 SUPER's PassMark G3D score of 34,245 and its DirectX 12 score of 134 indicate it handles modern APIs effectively. The Radeon Pro 580X has no PassMark results, so its DirectX performance cannot be directly quantified from the database. The RTX 4080 SUPER also shows strong FP32 compute at 52.22 TFLOPS versus 5.530 TFLOPS for the Radeon Pro 580X, which matters for scientific simulations, rendering, and other floating-point-heavy tasks.

Architecture Differences

The architectural gap between these two cards is generational. The RTX 4080 SUPER uses the AD103 chip built on Ada Lovelace architecture at TSMC's 5 nm process. It packs 45,900 million transistors into a 379 mm² die, yielding a transistor density of 121.1 million per mm². The Radeon Pro 580X uses the Ellesmere chip based on GCN 4.0 architecture, manufactured by GlobalFoundries at 14 nm. It has 5,700 million transistors on a 232 mm² die, with a density of 24.6 million per mm². The RTX 4080 SUPER has roughly 8 times the transistor count on a die that is only about 1.6 times larger.

Memory configurations differ sharply. The RTX 4080 SUPER has 16 GB of GDDR6X on a 256-bit bus, delivering 736.3 GB/s of bandwidth. The Radeon Pro 580X has 8 GB of GDDR5 on a 256-bit bus, providing 218.9 GB/s. Both use the same bus width, but the newer memory type and higher effective clock speed of 23 Gbps versus 6.8 Gbps give the RTX 4080 SUPER more than 3 times the bandwidth. The RTX 4080 SUPER also has 80 RT cores and 320 tensor cores, features entirely absent from the Radeon Pro 580X, which lists no RT or tensor core counts.

The compute resources are massively lopsided. The RTX 4080 SUPER has 10,240 shading units, 320 texture mapping units, and 112 ROPs. The Radeon Pro 580X has 2,304 shading units, 144 TMUs, and 32 ROPs. Pixel rate is 285.6 GPixel/s versus 38.40 GPixel/s, and texture rate is 816.0 GTexel/s versus 172.8 GTexel/s. The RTX 4080 SUPER's FP32 and FP16 throughput are both 52.22 TFLOPS with a 1:1 ratio, while the Radeon Pro 580X offers 5.530 TFLOPS in both, also at 1:1. Clock speeds reflect the different design goals: the RTX 4080 SUPER runs at 2295 MHz base and 2550 MHz boost, while the Radeon Pro 580X runs at 1100 MHz base and 1200 MHz boost.

API support also differs. The RTX 4080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro 580X supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RTX 4080 SUPER's newer DirectX feature level and higher Vulkan version give it access to more advanced rendering features. Power delivery differs as well: the RTX 4080 SUPER uses a 16-pin connector and suggests a 700 W PSU, while the Radeon Pro 580X has no listed power connectors or suggested PSU, consistent with its Apple MPX integration.

The Verdict

The data is unambiguous. The RTX 4080 SUPER outperforms the Radeon Pro 580X by more than 500% in both shared benchmark tests. For any workload that relies on OpenCL or Vulkan, the RTX 4080 SUPER is the clear choice. Its 52.22 TFLOPS of FP32 compute, 736.3 GB/s of memory bandwidth, and 16 GB of GDDR6X memory make it suitable for demanding rendering, AI inference, and high-end gaming. The Radeon Pro 580X, with 5.530 TFLOPS and 218.9 GB/s, is a legacy workstation part from 2019, suited only for light duties or specific Mac Pro environments where its Metal support and Apple MPX interface are required.

The RTX 4080 SUPER also has a much richer benchmark profile, with scores across DirectX 9 through 12, 2D acceleration, and compute. Its 86th percentile ranking places it near the top of the database, while the Radeon Pro 580X's 82nd percentile is respectable but reflects a much older and slower architecture. The RTX 4080 SUPER's launch MSRP is 999 USD, and it is now end-of-life, succeeded by the GeForce 50 series. The Radeon Pro 580X is also end-of-life, with no listed successor.

For a PC builder selecting between these two, the choice depends entirely on the platform. If building or upgrading a standard desktop PC with PCIe 4.0, the RTX 4080 SUPER is overwhelmingly faster in every measurable way. If working within a Mac Pro that requires the Apple MPX bus interface and Metal support, the Radeon Pro 580X is the only compatible option, though its performance is a fraction of the NVIDIA card's. The data does not support any scenario where the Radeon Pro 580X wins on raw performance.
