AMD Radeon Pro 575 vs NVIDIA RTX A5000 Comparison

The data in the database shows a decisive performance gap between the AMD Radeon Pro 575 and the NVIDIA RTX A5000. Across the shared benchmark suite, the RTX A5000 records a dominant victory, delivering scores that are several times higher than the Radeon Pro 575. The AMD card is an older, end-of-life mobile workstation part, while the NVIDIA card is a larger, more recent desktop workstation GPU, and the recorded measurements reflect this substantial difference in capability.

Head-to-Head Benchmarks

The direct comparison in the database includes two compute-oriented tests, and the NVIDIA RTX A5000 wins both by a wide margin. In Geekbench OpenCL, the RTX A5000 scores 157905, while the AMD Radeon Pro 575 scores 34596. This represents a delta of -78.1% for the AMD card, meaning the NVIDIA GPU is roughly 4.5 times faster in this workload. The margin is slightly smaller but still overwhelming in Geekbench Vulkan, where the RTX A5000 records 137828 against the Radeon Pro 575's 37878, a delta of -72.5%. Both results confirm that the RTX A5000's architecture and resources translate into a massive compute advantage.

The RTX A5000 also has a much broader set of recorded benchmarks, which helps contextualize its performance profile. Its Passmark G3D score is 22541, and its Passmark GPU Compute score is 12455. The AMD card lacks these specific measurements, but its average benchmark score of 39555 across its three recorded tests (Geekbench Metal, OpenCL, and Vulkan) is actually higher than the RTX A5000's average of 33622. This apparent contradiction is explained by the different test sets: the RTX A5000's average is dragged down by its very low Passmark DirectX scores (153 for DirectX 10, 187 for DirectX 11, 87 for DirectX 12, and 251 for DirectX 9), which are likely not directly comparable to the Geekbench scores. The head-to-head results, which use identical tests, are the clearest evidence of the NVIDIA card's superiority.

In the only two tests where both cards were measured, the RTX A5000 is not just ahead, it is ahead by a factor of several times. The OpenCL result of 157905 versus 34596 shows a lead of 123309 points. The Vulkan result shows a lead of 99950 points. These are not marginal wins; they represent a completely different performance class. The Radeon Pro 575's strongest recorded result, its Geekbench Metal score of 46192, is still far below the RTX A5000's OpenCL and Vulkan numbers, although Metal was not run on the NVIDIA card, so no direct comparison is possible there.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The AMD Radeon Pro 575 uses the Ellesmere chip based on GCN 4.0, fabricated on a 14 nm process at GlobalFoundries. The NVIDIA RTX A5000 uses the GA102 chip based on the Ampere architecture, fabricated on an 8 nm process at Samsung. This process difference is significant: the AMD chip is built on an older, less dense node, while NVIDIA's chip uses a newer process that allows for far more transistors.

The transistor counts reflect this gap. The AMD chip contains 5,700 million transistors on a die size of 232 mm², giving it a transistor density of 24.6 million per mm². The NVIDIA chip contains 28,300 million transistors on a die size of 628 mm², for a density of 45.1 million per mm². The RTX A5000 has nearly five times as many transistors and more than double the die area, which explains its much higher compute throughput.

The feature sets also diverge sharply. The RTX A5000 includes 64 ray tracing cores and 256 tensor cores, while the Radeon Pro 575 has none. This means the NVIDIA card is equipped for hardware-accelerated ray tracing and AI workloads, while the AMD card relies entirely on its standard shader array. In terms of API support, the RTX A5000 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Radeon Pro 575 supports DirectX 12 (12_0) and Vulkan 1.3. Both cards support OpenGL 4.6. The RTX A5000's newer API support aligns with its more modern Ampere design.

Specification Differences

The specification differences between the two cards are extensive and explain the performance gap. The Radeon Pro 575 has 4 GB of GDDR5 memory on a 256-bit bus, delivering 217.0 GB/s of bandwidth. The RTX A5000 has 24 GB of GDDR6 memory on a 384-bit bus, delivering 768.0 GB/s. That is six times the memory capacity and more than three times the bandwidth.

The compute unit counts are also vastly different. The Radeon Pro 575 has 2048 shading units, 128 texture mapping units, and 32 ROPs. The RTX A5000 has 8192 shading units, 256 TMUs, and 96 ROPs. The NVIDIA card has four times the shading units, double the TMUs, and three times the ROPs. Pixel rate is 35.07 GPixel/s for the AMD card versus 162.7 GPixel/s for the NVIDIA card. Texture rate is 140.3 GTexel/s versus 433.9 GTexel/s. FP32 throughput is 4.489 TFLOPS versus 27.77 TFLOPS, and FP16 is also 4.489 TFLOPS versus 27.77 TFLOPS (both at 1:1 ratios).

The physical and power characteristics differ as well. The Radeon Pro 575 is an MXM module with a TDP of 150 W and no power connectors. The RTX A5000 is a dual-slot card, 267 mm long and 112 mm high, with a single 8-pin power connector, a TDP of 230 W, and a suggested PSU of 550 W. The bus interface is PCIe 3.0 x16 for the AMD card and PCIe 4.0 x16 for the NVIDIA card. The AMD card's display outputs are listed as portable device dependent, while the RTX A5000 has 4x DisplayPort 1.4a outputs. The RTX A5000 also has defined clock speeds (1170 MHz base, 1695 MHz boost), while the Radeon Pro 575's base and boost clocks are not recorded. The release dates are also far apart: the Radeon Pro 575 launched in 2017, and the RTX A5000 in 2021.

The Verdict

The data points to a clear verdict: the NVIDIA RTX A5000 is the far more capable GPU in every head-to-head measurement available. In both Geekbench OpenCL and Geekbench Vulkan, it outperforms the AMD Radeon Pro 575 by a factor of roughly three and a half to four and a half times. The RTX A5000's hardware resources, including its 8192 shading units, 24 GB of memory, and 768.0 GB/s of bandwidth, are in a different league from the Radeon Pro 575's 2048 shading units, 4 GB of memory, and 217.0 GB/s of bandwidth.

The Radeon Pro 575's higher average benchmark score of 39555 versus 33622 is a statistical artifact of the different test sets, not evidence of superior performance. When the same tests are run on both cards, the RTX A5000 wins outright. The AMD card's end-of-life status and 2017 release date, combined with its GCN 4.0 architecture and lack of ray tracing or tensor cores, place it firmly in an older performance tier. The RTX A5000, despite also being end-of-life, benefits from a much newer Ampere architecture, a larger die, and a far more robust feature set.

Where Each One Wins

The NVIDIA RTX A5000 wins in every scenario supported by the recorded data. In OpenCL compute workloads, it is the clear choice, with a score of 157905 versus 34596. In Vulkan workloads, it again dominates with 137828 versus 37878. Its hardware ray tracing cores and tensor cores give it capabilities that the Radeon Pro 575 simply does not have, making it suitable for rendering, AI inference, and other modern workstation tasks. Its 24 GB of memory and 768.0 GB/s bandwidth also make it the better option for large datasets and high-resolution textures.

The AMD Radeon Pro 575's only recorded advantage is its average benchmark score, which is higher only because the RTX A5000's test set includes several very low Passmark DirectX scores. In terms of actual head-to-head performance, the AMD card does not win a single test in the database. Its smaller 4 GB memory footprint and lower bandwidth limit it to lighter workloads. The Radeon Pro 575 also has a lower TDP of 150 W versus 230 W and an MXM module form factor, which may make it easier to integrate into compact or portable systems, but this is a physical design choice rather than a performance win. For any user prioritizing compute performance, the RTX A5000 is the only rational pick based on the recorded measurements.
