AMD Radeon Pro 575X vs NVIDIA RTX A5000 Comparison

Head-to-Head Benchmarks

The benchmark data in this comparison is decisive, though the available test coverage is narrow. Two shared workloads appear in the database for both cards, and the NVIDIA RTX A5000 wins both by a substantial margin.

In Geekbench OpenCL, the AMD Radeon Pro 575X records a score of 34,773. The NVIDIA RTX A5000 reaches 157,905 in the same test. That places the RTX A5000 approximately 78% ahead. This is not a marginal victory; the NVIDIA card delivers nearly four and a half times the raw compute output in this workload. The delta is consistent with the massive difference in shading units, memory bandwidth, and FP32 throughput listed in the specification records.

The Geekbench Vulkan test shows a similar pattern. The AMD card posts 37,919, while the NVIDIA RTX A5000 scores 137,828. The RTX A5000 leads by roughly 72.5%. Vulkan is often a strong API for AMD hardware due to its low-level access and GCN architecture heritage, but the data here does not support that narrative. The sheer compute advantage of the Ampere-based card overpowers any architectural efficiency gains the older GCN design might offer.

The head-to-head summary shows a clean sweep: the NVIDIA RTX A5000 wins both recorded benchmarks, and the AMD Radeon Pro 575X has zero wins. The delta percentages are steep, 78% in OpenCL and 72.5% in Vulkan. Each of these is a dominant result, not a close call.

It is also worth placing these results in the context of each card’s broader database standing. The AMD Radeon Pro 575X holds an average benchmark score of 39,116 across its recorded tests, placing it in the 82nd percentile of all GPUs in the database. Its nearest rivals include the AMD Radeon Pro 580X (38,706, within 1.1%) and the NVIDIA GeForce MX570 A (38,691, also within 1.1%). The Radeon Pro 575X is slightly ahead of those cards. On the other side, the NVIDIA RTX A5000 has an average score of 33,622 across its broader test set, which includes many legacy DirectX and Passmark workloads. That places it in the 78th percentile. Its nearest rivals include the NVIDIA GeForce GTX 1060 5 GB (33,694, within 0.2%) and the AMD Radeon RX 480 (33,997, within 1.1%). The averages are not directly comparable because the test suites differ, but they show that the RTX A5000’s average is pulled down by older API tests, while its compute and modern API scores are far higher.

Where Each One Wins

The use-case split is stark based on the recorded data. The NVIDIA RTX A5000 wins every shared workload. In compute-heavy tasks that rely on OpenCL, such as rendering, physics simulation, or general-purpose GPU acceleration, the RTX A5000 is the clear choice. Its OpenCL score of 157,905 versus 34,773 demonstrates a massive workload advantage. For Vulkan-based graphics or compute applications, the same conclusion applies, with the RTX A5000 scoring 137,828 versus 37,919.

The AMD Radeon Pro 575X does not win any recorded benchmark in this head-to-head. However, it can still be positioned for specific scenarios. The data shows it performs within 1.1% of the AMD Radeon Pro 580X and the NVIDIA GeForce MX570 A in average score, so it sits in a performance class well below the RTX A5000. Where the 575X might be suitable is in lightweight or legacy workflows that do not demand high compute throughput. Its GCN 4.0 architecture supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, which covers older professional applications. The card is also an integrated graphics processor (IGP) with no power connectors and a 150 W TDP, so it fits in systems where physical space and power delivery are limited. The RTX A5000, being a dual-slot card with a 230 W TDP and a single 8-pin power connector, requires a more robust platform.

For users who need 24 GB of VRAM, the RTX A5000 is the only option in this comparison. The AMD card offers 4 GB. For large datasets, high-resolution textures, or AI inference tasks that hold large models in memory, the RTX A5000’s memory capacity is decisive. The AMD card’s 4 GB is a constraint for modern workloads.

Architecture Differences

The architectural gap between these two cards is generational. The AMD Radeon Pro 575X uses the Ellesmere chip based on GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. The NVIDIA RTX A5000 uses the GA102 chip based on Ampere architecture, manufactured on an 8 nm process at Samsung. This is a significant node difference, and the transistor counts reflect it.

The AMD chip contains 5,700 million transistors on a 232 mm² die, giving a transistor density of 24.6 million per square millimeter. The NVIDIA chip contains 28,300 million transistors on a 628 mm² die, with a density of 45.1 million per square millimeter. The RTX A5000 has nearly five times the transistor count and a much denser design.

The memory architecture is also very different. The AMD Radeon Pro 575X uses 4 GB of GDDR5 on a 256-bit bus, running at 6.8 Gbps effective. This yields 217.0 GB/s of bandwidth. The NVIDIA RTX A5000 uses 24 GB of GDDR6 on a 384-bit bus, running at 16 Gbps effective, for 768.0 GB/s of bandwidth. That is more than three times the bandwidth and six times the memory capacity.

Compute resources scale accordingly. The AMD card has 2048 shading units, 128 texture mapping units, and 32 ROPs. The RTX A5000 has 8192 shading units, 256 TMUs, and 96 ROPs. The pixel rate for the AMD is 35.07 GPixel/s, while the NVIDIA achieves 162.7 GPixel/s. The texture rate is 140.3 GTexel/s versus 433.9 GTexel/s. FP32 throughput is 4.489 TFLOPS for the AMD and 27.77 TFLOPS for the NVIDIA, a six-fold difference. Both cards have 1:1 FP16 and FP32 ratios, so the FP16 numbers match their FP32 counts.

The RTX A5000 also includes dedicated hardware for ray tracing: 64 RT cores and 256 tensor cores. The AMD Radeon Pro 575X has none, as GCN 4.0 predates ray tracing acceleration and tensor processing. This makes the RTX A5000 suitable for DXR workloads, while the AMD relies on compute or software-based rays.

The API support differs as well. The AMD supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The NVIDIA supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Vulkan 1.4 is newer and includes additional extensions. DirectX 12 Ultimate brings features like ray tracing and variable rate shading, linking the API support to the RT cores.

The bus interface is also different: the AMD is PCIe 3.0 x16, while the NVIDIA is PCIe 4.0 x16. The RTX A5000 can use double the bandwidth on supported systems, which benefits data transfer for large datasets. The NVIDIA also has four DisplayPort 1.4a outputs, while the AMD’s display outputs are listed as “Portable Device Dependent,” because it is an integrated part of a Mac system.
