AMD Radeon Pro 580 vs NVIDIA GeForce RTX 3080 Ti Comparison

# Head-to-Head Benchmarks

The benchmark data presents an unambiguous picture: the NVIDIA GeForce RTX 3080 Ti dominates the AMD Radeon Pro 580 in every shared test, with margins that are nothing short of generational. In Geekbench OpenCL, the RTX 3080 Ti scores 170,037 against the Radeon Pro 580's 38,457, a delta of 342.1% — meaning the NVIDIA card delivers more than four times the raw compute throughput in this workload. The Vulkan comparison is even more lopsided, with the RTX 3080 Ti hitting 192,697 versus the AMD card's 43,285, a 345.2% advantage. These are not incremental gains; they represent a fundamental leap in processing capability.

Looking at the broader benchmark landscape, the RTX 3080 Ti's average benchmark score across all tests stands at 41,187, placing it in the 83rd percentile of all GPUs. The Radeon Pro 580, with an average score of 40,318, sits at the 82nd percentile. While the percentile gap appears narrow — just one percentage point — the absolute performance difference in head-to-head tests tells a more dramatic story. The RTX 3080 Ti's nearest rivals include the AMD Radeon Pro 5300 (averaging 40,870, just 0.8% behind) and the NVIDIA Tesla M40 24 GB (41,707, 1.2% ahead), indicating that its aggregate score is competitive with professional workstation cards from a similar era. The Radeon Pro 580's nearest rival list shows it trading blows with the NVIDIA GeForce RTX 5070 (40,377, a 0.1% deficit) and the AMD Radeon Pro WX 7100 (40,063, 0.6% behind).

The head-to-head results reveal that the RTX 3080 Ti wins both shared tests decisively. In OpenCL, the 342.1% margin means the NVIDIA card processes roughly 4.4 times the work per unit time. In Vulkan, the 345.2% gap is nearly identical in proportion, suggesting that the architectural advantages scale consistently across different API paradigms. The Radeon Pro 580 has no benchmark victories to claim in this comparison — its sole competitive arena is the Metal API, where it scores 39,213, but no corresponding Metal score exists for the RTX 3080 Ti in the data, leaving that comparison undefined.

For context, the RTX 3080 Ti also posts substantial scores in other tests not shared with the AMD card: 26,896 in Passmark G3D, 15,282 in Passmark GPU Compute, and 5,077 in 3DMark Steel Nomad DX12. The Radeon Pro 580's only other data point is that Metal score, which falls below every non-Metal result the NVIDIA card achieves except the Passmark DirectX 12 test (110) and Passmark DirectX 10 (184). Even the RTX 3080 Ti's weakest DirectX result — 110 in Passmark DirectX 12 — is dwarfed by its OpenCL and Vulkan numbers, underscoring that the NVIDIA architecture excels across compute-heavy workloads.

# Architecture Differences

The underlying silicon tells a story of two vastly different design philosophies separated by four years of process technology evolution. The RTX 3080 Ti uses NVIDIA's GA102 chip built on Ampere architecture, fabricated on Samsung's 8 nm process. This is a massive die: 628 mm² housing 28,300 million transistors, yielding a density of 45.1 million transistors per square millimeter. In contrast, the Radeon Pro 580 employs AMD's Ellesmere chip based on GCN 4.0 architecture, produced on GlobalFoundries' 14 nm node. Its die is 232 mm² with 5,700 million transistors, giving a density of 24.6M/mm². The RTX 3080 Ti packs nearly five times the transistor count into roughly 2.7 times the die area — a clear indicator of both process advantage and design complexity.

The compute resources diverge sharply. The RTX 3080 Ti fields 10,240 shading units, 320 texture mapping units, and 112 ROPs, alongside 80 dedicated ray tracing cores and 320 tensor cores. The Radeon Pro 580 offers 2,304 shading units, 144 TMUs, and just 32 ROPs, with no ray tracing or tensor core hardware whatsoever. This translates to a raw throughput gap that mirrors the benchmark results: the NVIDIA card delivers 34.10 TFLOPS of FP32 performance versus 5.530 TFLOPS for the AMD card, a 6.2x difference. FP16 performance is equally skewed, with the RTX 3080 Ti achieving 34.10 TFLOPS (1:1 with FP32) against the Radeon Pro 580's 5.530 TFLOPS (also 1:1).

Memory architecture amplifies the disparity. The RTX 3080 Ti uses 12 GB of GDDR6X across a 384-bit bus, yielding 912.4 GB/s of bandwidth. The Radeon Pro 580 has 8 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s. That is a 4.2x bandwidth advantage for the NVIDIA card. Clock speeds tell a subtler story: the RTX 3080 Ti runs at 1365 MHz base and 1665 MHz boost, while the Radeon Pro 580 operates at 1100 MHz base and 1200 MHz boost. The NVIDIA card's higher clocks compound its architectural lead. Pixel and texture rates follow suit: 186.5 GPixel/s and 532.8 GTexel/s for the RTX 3080 Ti versus 38.40 GPixel/s and 172.8 GTexel/s for the Radeon Pro 580.

Power and physical characteristics differ markedly. The RTX 3080 Ti is a 350 W dual-slot card requiring a 1x 12-pin power connector and a 750 W suggested PSU, measuring 285 mm in length. The Radeon Pro 580 is an IGP (integrated graphics processor) with a 185 W TDP, no external power connectors, and dimensions listed as "Portable Device Dependent" — reflecting its intended deployment in Apple Mac systems. The RTX 3080 Ti supports PCIe 4.0 x16, while the Radeon Pro 580 uses PCIe 3.0 x16. Display outputs also diverge: the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, whereas the AMD card's outputs are portable-device dependent. API support shows the NVIDIA card supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the Radeon Pro 580 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

# Where Each One Wins

The NVIDIA GeForce RTX 3080 Ti wins comprehensively in every measurable category covered by the data. In compute-heavy workloads — represented by Geekbench OpenCL and Vulkan — the RTX 3080 Ti's 342.1% and 345.2% margins respectively over the Radeon Pro 580 make it the clear choice for tasks like GPU-accelerated rendering, scientific simulation, and machine learning inference. Its 34.10 TFLOPS of FP32 throughput, 80 dedicated ray tracing cores, and 320 tensor cores provide hardware-accelerated features that the Radeon Pro 580 simply lacks. The 12 GB GDDR6X memory with 912.4 GB/s bandwidth supports larger datasets and texture-heavy workloads without bottlenecking, a critical advantage for 4K texturing and large model training.

The Radeon Pro 580's niche is defined by its form factor and integration rather than raw performance. As an IGP with a 185 W TDP and no external power connectors, it is designed for portable Mac systems where power and space are at a premium. Its PCIe 3.0 x16 interface and portable-device-dependent display outputs reflect a mobile-first design philosophy. In its home environment — likely a laptop or all-in-one Mac — the Radeon Pro 580 delivers 5.530 TFLOPS of FP32 performance and 217.0 GB/s of bandwidth, which is respectable for its 2017-era 14 nm process node. It supports Vulkan 1.3 and DirectX 12 (12_0), making it adequate for mainstream productivity and light 3D workloads.

For any user who needs maximum compute throughput, the RTX 3080 Ti is categorically superior. The data shows no scenario in the shared benchmark suite where the Radeon Pro 580 comes close. However, the choice between these two cards will likely be dictated by system constraints: the RTX 3080 Ti demands a 350 W TDP, a 750 W PSU, dual-slot space, and 285 mm of chassis clearance, while the Radeon Pro 580 slots into a portable system with no additional power cabling. In terms of percentile ranking, both cards sit within one percentage point of each other (83rd versus 82nd percentile) when averaged across all GPUs, but this aggregate metric is skewed by the RTX 3080 Ti's many additional benchmark scores. The head-to-head numbers leave no ambiguity about which GPU delivers superior performance when both can be deployed.
