AMD Radeon Pro 580X vs NVIDIA TITAN V Comparison

AMD Radeon Pro 580X vs NVIDIA TITAN V is a matchup between two very different products: one is an integrated-class Apple MPX part aimed at Mac workflows, the other a dual-slot desktop behemoth from the Volta generation. The data shows a clear performance gap, but the Radeon Pro 580X still holds relevance in specific contexts. Here is how they compare.

Where Each One Wins

The NVIDIA TITAN V wins every head-to-head benchmark recorded in the data, and it wins by a wide margin. In Geekbench OpenCL, the TITAN V scores 157265 against the Radeon Pro 580X’s 36426, a delta of -76.8% for the AMD card. In Geekbench Vulkan, the TITAN V scores 152117 versus 40115, a -73.6% gap. That means the TITAN V is roughly four times faster in both compute APIs. If your workload is raw throughput—OpenCL or Vulkan compute—the TITAN V is the only rational choice.

The Radeon Pro 580X wins nowhere in the head-to-head data. Its wins are contextual: it is an IGP (integrated graphics processor) designed for Apple MPX bus systems, so it fits environments where a dual-slot, 267 mm, 250 W card with a 1x 6-pin + 1x 8-pin connector cannot go. The TITAN V’s slot width, power connectors, and physical dimensions (267 mm length, 112 mm height, 40 mm width) make it incompatible with tightly integrated Mac chassis. The Radeon Pro 580X’s 2x HDMI 2.0b outputs also serve a different display configuration than the TITAN V’s 1x HDMI 2.0 and 3x DisplayPort 1.4a. In short, the TITAN V wins on performance; the Radeon Pro 580X wins on platform fit.

Architecture Differences

The two GPUs come from opposite design philosophies. The Radeon Pro 580X uses AMD’s GCN 4.0 architecture on a 14 nm process from GlobalFoundries, with a die size of 232 mm² and 5,700 million transistors. That yields a transistor density of 24.6M per mm². The NVIDIA TITAN V uses Volta on a 12 nm TSMC process, packing 21,100 million transistors into an 815 mm² die—a density of 25.9M per mm². The TITAN V’s die is over 3.5 times larger in area and holds nearly 4 times the transistors.

Core resources differ massively. The Radeon Pro 580X has 2304 shading units, 144 texture mapping units, and 32 ROPs. The TITAN V has 5120 shading units, 320 TMUs, and 96 ROPs. The TITAN V also brings 640 tensor cores, which the Radeon lacks entirely. Neither card has ray tracing cores. Memory subsystems are also divergent: the Radeon uses 8 GB of GDDR5 on a 256-bit bus with 218.9 GB/s bandwidth, while the TITAN V uses 12 GB of HBM2 on a 3072-bit bus with 651.3 GB/s bandwidth—roughly 3 times the bandwidth. Clock speeds favor the TITAN V as well: base 1200 MHz versus 1100 MHz, boost 1455 MHz versus 1200 MHz.

Compute throughput tells the story. The Radeon Pro 580X delivers 5.530 TFLOPS FP32 and 5.530 TFLOPS FP16 (1:1 ratio). The TITAN V delivers 14.90 TFLOPS FP32 and 29.80 TFLOPS FP16 (2:1 ratio). The TITAN V is 2.7 times faster in FP32 and 5.4 times faster in FP16. Pixel and texture rates follow: 139.7 GPixel/s and 465.6 GTexel/s for the TITAN V versus 38.40 GPixel/s and 172.8 GTexel/s for the Radeon. The TITAN V supports DirectX 12_1 and Vulkan 1.4; the Radeon supports DirectX 12_0 and Vulkan 1.3. Both support OpenGL 4.6.

FAQ

Q: Which card has higher average benchmark scores across all tests?

A: The Radeon Pro 580X has an average benchmark score of 38706, while the TITAN V’s average is 34355. However, this average is misleading because the TITAN V’s dataset includes many Passmark tests (DirectX 9, 10, 11, 12, G2D, G3D, compute) that score low (e.g., 153, 152, 81, 213, 937, 19805, 9263), dragging its average down despite its dominant OpenCL and Vulkan scores.

Q: In the head-to-head benchmarks, what is the largest performance gap?

A: The largest gap is in Geekbench OpenCL, where the TITAN V scores 157265 versus the Radeon’s 36426, a delta of -76.8% (meaning the Radeon is 76.8% slower). The Vulkan gap is slightly smaller at -73.6%.

Q: Does the Radeon Pro 580X have any compute advantage over the TITAN V?

A: No. The Radeon Pro 580X’s FP16 throughput is identical to its FP32 (5.530 TFLOPS, 1:1), whereas the TITAN V’s FP16 is double its FP32 (29.80 TFLOPS, 2:1). In every recorded compute benchmark, the TITAN V wins.

Q: What memory type and bus width does each card use?

A: The Radeon Pro 580X uses 8 GB of GDDR5 on a 256-bit bus with 218.9 GB/s bandwidth. The TITAN V uses 12 GB of HBM2 on a 3072-bit bus with 651.3 GB/s bandwidth.

Q: Are both cards still in production?

A: No. Both are marked as End-of-life in the data. The Radeon Pro 580X was released on 2019-03-17, while the TITAN V was released earlier on 2017-12-06.

Q: Which card has a higher percentile ranking among all GPUs?

A: The Radeon Pro 580X sits at the 82nd percentile, while the TITAN V sits at the 79th percentile. This again reflects the TITAN V’s mixed benchmark set, not its actual compute capability.

Head-to-Head Benchmarks

The head-to-head data contains exactly two tests, and the TITAN V dominates both. In Geekbench OpenCL, the Radeon Pro 580X scores 36426, while the TITAN V scores 157265. The delta is -76.8%, meaning the AMD card delivers less than a quarter of the TITAN V’s OpenCL throughput. This is consistent with the raw specs: the TITAN V has 2.7 times the FP32 rate and 5.4 times the FP16 rate, plus over 2.9 times the memory bandwidth.

In Geekbench Vulkan, the Radeon Pro 580X scores 40115, slightly higher than its OpenCL score, but the TITAN V again reaches 152117. The delta is -73.6%. The TITAN V’s Vulkan score is actually slightly lower than its OpenCL score, but that does not close the gap—the Radeon still trails by a factor of about 3.8. The wins tally is 0 for the Radeon Pro 580X and 2 for the TITAN V.

Notably, the Radeon Pro 580X’s own benchmark suite (Geekbench Metal, OpenCL, Vulkan) shows scores of 39577, 36426, and 40115, giving an average of 38706. The TITAN V’s broader suite includes Passmark tests where it scores as low as 81 (DirectX 12) and 152 (DirectX 11), but its compute-focused results (Geekbench OpenCL 157265, Vulkan 152117, Passmark G3D 19805, GPU Compute 9263) are far above the Radeon’s. The average score of 34355 for the TITAN V is dragged down by these legacy DirectX tests, which likely reflect driver or architecture quirks rather than real-world capability.

The Verdict

The NVIDIA TITAN V is the superior card by every performance metric in the data. It is faster in OpenCL, faster in Vulkan, has more than double the FP32 throughput, more than five times the FP16 throughput, and nearly three times the memory bandwidth. Its 640 tensor cores add a feature the Radeon Pro 580X cannot match. If you need compute power, the TITAN V is the clear pick.

The Radeon Pro 580X is not without a purpose, but that purpose is narrow. It is an IGP with an Apple MPX bus interface, meaning it is designed to slot into Mac systems where a 250 W, dual-slot, 600 W PSU-requiring card like the TITAN V physically cannot fit. The Radeon’s 185 W TDP and 2x HDMI 2.0b outputs suit a specific integrated chassis. For users on that platform, the Radeon Pro 580X is the only option among these two, but its performance—at roughly 23-27% of the TITAN V’s compute scores—should temper expectations.

Choose the TITAN V if you have the slot space, power delivery, and need maximum compute. Choose the Radeon Pro 580X only if your system dictates an MPX form factor and you accept a large performance compromise. The data does not support any other conclusion.
