AMD Radeon Pro 580X vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data contains a single directly comparable benchmark between the AMD Radeon Pro 580X and the NVIDIA RTX PRO 4500 Blackwell: the Geekbench Vulkan test. This is a decisive result. The NVIDIA RTX PRO 4500 Blackwell scores 221,768 points, while the AMD Radeon Pro 580X scores 40,115 points. The delta is reported as -81.9% from the perspective of the AMD part, meaning the NVIDIA card outperforms it by a factor of roughly 5.5x. This is not a marginal generational gap; it is a categorical separation in raw compute throughput under the Vulkan API.

The AMD Radeon Pro 580X does have its own benchmark history across three tests. Its Geekbench Metal score is 39,577, its OpenCL score is 36,426, and its Vulkan score is 40,115. These are internally consistent, with the Vulkan result being the highest of the three. The NVIDIA RTX PRO 4500 Blackwell, by contrast, has a broader benchmark profile. Its Passmark G3D score is 33,360, its Passmark GPU Compute score is 19,255, and its 3DMark Steel Nomad DX12 score is 7,025. The Passmark DirectX 11 score is 320, DirectX 10 is 204, DirectX 9 is 397, and DirectX 12 is 119. The Passmark G2D score is 1,336. These figures cannot be compared directly to the AMD Geekbench results, but they paint a picture of a card that is designed for sustained, varied workloads rather than a single synthetic peak.

When examining the average benchmark scores, the AMD Radeon Pro 580X posts an average of 38,706 across its recorded tests, while the NVIDIA RTX PRO 4500 Blackwell averages 31,532. This apparent inversion is an artifact of the test sets: the AMD card's average is drawn from three Geekbench compute tests, while the NVIDIA card's average includes the much lower Passmark DirectX scores, which drag down its mean. The raw Vulkan head-to-head is the only apples-to-apples comparison, and it strongly favors NVIDIA.

The nearest rivals for each card further contextualize their standing. The AMD Radeon Pro 580X sits at the 82nd percentile of all GPUs in the database. Its closest competitor is the AMD Radeon Pro 575X, which averages 39,116, a delta of -1% relative to the 580X. The NVIDIA GeForce MX570 A is essentially tied at 38,691 with a delta of 0%, and the GeForce RTX 5080 Mobile is 0.9% behind at 38,349. The GeForce MX570 trails by 1.1% at 38,299. This cluster of rivals around the 38,000 to 39,000 mark shows that the 580X, despite its age, holds its own against a narrow band of mobile and workstation parts in aggregate scoring.

The NVIDIA RTX PRO 4500 Blackwell, at the 76th percentile, has a different competitive set. Its nearest rival is the Intel Arc Pro A30M, which averages 31,894, a delta of -1.1%. The NVIDIA TITAN RTX is 0.5% ahead at 31,676, while the GRID M60-1Q and Quadro M5000 are both 1% ahead at 31,220 and 31,206 respectively. These deltas are small, indicating that the RTX PRO 4500 Blackwell's average score places it in a tightly packed tier. The gap between its Vulkan score and its average score is substantial, suggesting that its aggregate performance is pulled down by the legacy DirectX tests, which are not representative of its modern compute capabilities.

Architecture Differences

The two cards are built on fundamentally different architectures and process technologies. The AMD Radeon Pro 580X uses the Ellesmere chip, based on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. The chip contains 5,700 million transistors on a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip, based on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. This chip packs 45,600 million transistors onto a 378 mm² die, for a density of 120.6 million per square millimeter. The density advantage is roughly 4.9x, which reflects the massive process node leap.

The compute layout differs dramatically. The AMD card has 2,304 shading units, 144 texture mapping units, and 32 raster operation units. It has no dedicated ray tracing cores and no tensor cores. The NVIDIA card has 10,496 shading units, 328 TMUs, and 112 ROPs. It also includes 82 ray tracing cores and 328 tensor cores. The presence of dedicated RT and tensor hardware is a structural difference, not just a numerical one. Any workload that relies on ray tracing or AI acceleration will see a fundamentally different performance profile.

Clock behavior also diverges. The AMD card has a base clock of 1100 MHz and a boost clock of 1200 MHz, a modest 100 MHz spread. The NVIDIA card has a base clock of 1635 MHz and a boost clock of 2407 MHz, a 772 MHz spread. The NVIDIA boost clock is exactly double the AMD boost clock plus 7 MHz. This clock advantage compounds with the shading unit count to produce the massive Vulkan score difference.

The memory architectures are equally distinct. The AMD card uses 8 GB of GDDR5 on a 256-bit bus, with memory clocked at 1710 MHz (6.8 Gbps effective) and bandwidth of 218.9 GB/s. The NVIDIA card uses 32 GB of GDDR7 on a 256-bit bus, with memory clocked at 1750 MHz (28 Gbps effective) and bandwidth of 896.0 GB/s. The NVIDIA card has 4x the capacity and roughly 4.1x the bandwidth. Both use a 256-bit bus, so the bandwidth gain comes entirely from the faster GDDR7 memory.

API support differs as well. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_2 feature level on the NVIDIA card enables hardware ray tracing and mesh shaders, which the AMD card's 12_0 level cannot match.

Specification Differences

The physical and electrical specifications show a clear generational shift. The AMD Radeon Pro 580X is an integrated graphics processor (IGP) with a slot width of IGP and no power connectors listed. It has a TDP of 185 W. The NVIDIA RTX PRO 4500 Blackwell is a dual-slot card with a 16-pin power connector and a suggested PSU of 550 W. Its TDP is 200 W, only 15 W higher than the AMD card despite the enormous compute difference.

The bus interfaces differ. The AMD card uses Apple MPX, while the NVIDIA card uses PCIe 5.0 x16. Display outputs also diverge: the AMD card has 2x HDMI 2.0b, while the NVIDIA card has 4x DisplayPort 2.1b. The NVIDIA card has recorded physical dimensions of 267 mm length, 111 mm height, and 40 mm width. The AMD card has no recorded dimensions.

The production status and release dates reflect their lifecycles. The AMD card is end-of-life and was released on 2019-03-17. The NVIDIA card is active and was released on 2025-03-17, exactly six years later to the day. The NVIDIA card's predecessor is listed as Workstation Ada, while the AMD card has no predecessor or successor listed.

The remaining differences are in raw compute throughput. The AMD card has a pixel rate of 38.40 GPixel/s, a texture rate of 172.8 GTexel/s, FP32 of 5.530 TFLOPS, and FP16 of 5.530 TFLOPS (1:1). The NVIDIA card has a pixel rate of 269.6 GPixel/s, a texture rate of 789.5 GTexel/s, FP32 of 50.53 TFLOPS, and FP16 of 50.53 TFLOPS (1:1). The NVIDIA card is roughly 7x faster in pixel rate, 4.6x faster in texture rate, and 9.1x faster in FP32 and FP16.

The Verdict

The data is unambiguous for anyone choosing between these two cards. The NVIDIA RTX PRO 4500 Blackwell wins the only direct benchmark comparison by a staggering margin, with a Geekbench Vulkan score of 221,768 versus 40,115 for the AMD Radeon Pro 580X. The delta of -81.9% for the AMD card means the NVIDIA card is over five times faster in that test. For any workload that uses Vulkan, the NVIDIA card is the only rational choice.

The AMD Radeon Pro 580X does have a higher percentile ranking (82nd versus 76th), but this is a function of the test set, not a sign of superior performance. Its nearest rivals, including the GeForce MX570 A and the Radeon Pro 575X, are all clustered within 1% of its average score. The NVIDIA card's nearest rivals, including the TITAN RTX and Quadro M5000, are similarly clustered but at a different performance level. The average scores are not directly comparable because the tests are different.

The architecture differences reinforce the benchmark results. The NVIDIA card has 4.5x the shading units, 2.3x the TMUs, 3.5x the ROPs, and dedicated ray tracing and tensor cores. It has 4x the memory capacity and 4.1x the bandwidth. Its boost clock is 2,407 MHz versus 1,200 MHz. Every structural advantage points the same way.

The AMD card's only advantages are its IGP form factor, its Apple MPX bus interface, and its end-of-life status, which may suit a legacy Mac environment. But for raw performance, the NVIDIA RTX PRO 4500 Blackwell is the clear winner. The verdict is simple: choose the NVIDIA card for modern compute, ray tracing, or high-bandwidth workloads. The AMD card is only relevant for systems that specifically require its Apple MPX integration and cannot accommodate a dual-slot PCIe card.
