AMD Radeon Pro 575X vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Radeon Pro 575X and the NVIDIA RTX A1000 is decisively one-sided, with the RTX A1000 winning both recorded head-to-head tests. In Geekbench OpenCL, the RTX A1000 scores 52,078 against the Radeon Pro 575X's 34,773, a 33.2% advantage. The Vulkan result tells a similar story: the RTX A1000 posts 49,574 versus 37,919 for the AMD card, a 23.5% lead. These are not marginal differences; the NVIDIA card is substantially ahead in both compute APIs, with the OpenCL gap being particularly pronounced.

Looking at the broader database context, the RTX A1000's average benchmark score of 34,207 places it just ahead of the NVIDIA RTX A2000 12 GB, which averages 34,154, a 0.2% difference. The RTX A1000 also edges out the AMD Radeon RX 560 XT by 0.2% and the AMD Radeon RX 480 by 0.6%. Its closest challenger from above is the NVIDIA TITAN V, which scores 34,355, meaning the RTX A1000 trails that card by a mere 0.4%. The Radeon Pro 575X, by contrast, has an average benchmark score of 39,116, which places it in a different competitive tier entirely.

The Radeon Pro 575X's average score puts it 1.1% ahead of both the AMD Radeon Pro 580X and the NVIDIA GeForce MX570 A, while it also sits 1.1% behind the AMD Radeon Pro 575 and the NVIDIA RTX A500 Mobile. This clustering around the 38,700 to 39,600 score range indicates that the Radeon Pro 575X is competitive within its immediate peer group, but that group operates at a lower performance level than what the RTX A1000 achieves. The percentile rankings reinforce this: the Radeon Pro 575X sits at the 82nd percentile among all GPUs, while the RTX A1000 sits at the 79th percentile. Despite the RTX A1000 winning every direct comparison, its overall percentile is lower, which suggests that the database's broader GPU population includes many cards that outperform both of these workstation parts.

The per-test results also reveal something about workload characteristics. The RTX A1000's OpenCL advantage of 33.2% is larger than its Vulkan advantage of 23.5%. This could indicate that the NVIDIA card's architecture handles OpenCL's execution model more efficiently relative to the AMD part, or that the Radeon Pro 575X's GCN design is comparatively stronger in Vulkan workloads. Either way, the direction of the results is consistent: the RTX A1000 is the faster card in every measured scenario.

Architecture Differences

The two GPUs come from fundamentally different architectural generations and manufacturing processes. The AMD Radeon Pro 575X is built on GCN 4.0 architecture, using the Ellesmere chip, and is fabricated on a 14 nm process at GlobalFoundries. The NVIDIA RTX A1000 uses the Ampere architecture with the GA107 chip, manufactured on an 8 nm process at Samsung. This process difference is significant: the AMD chip packs 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The NVIDIA chip crams 8,700 million transistors into a smaller 200 mm² die, achieving a density of 43.5 million per square millimeter, nearly double the AMD part's density.

The shader configurations differ as well. The Radeon Pro 575X has 2,048 shading units, 128 texture mapping units, and 32 raster output units. The RTX A1000 has 2,304 shading units, 72 texture mapping units, and 32 raster output units. While the NVIDIA card has more shading units, it has significantly fewer texture units, which explains some of the performance profile differences. The RTX A1000 also brings dedicated hardware that the AMD card lacks entirely: 18 ray tracing cores and 72 tensor cores. These are absent from the Radeon Pro 575X, reflecting the AMD part's older GCN design that predates dedicated ray tracing and tensor processing hardware.

Memory subsystems take different approaches. The Radeon Pro 575X uses 4 GB of GDDR5 on a 256 bit bus, delivering 217.0 GB/s of bandwidth. The RTX A1000 uses 8 GB of GDDR6 on a 128 bit bus, delivering 192.0 GB/s. The AMD card has a wider bus and higher bandwidth, but the NVIDIA card offers double the capacity with slightly lower bandwidth. The memory clock speeds reflect this: the Radeon Pro 575X runs at 1,695 MHz, translating to 6.8 Gbps effective, while the RTX A1000 runs at 1,500 MHz with 12 Gbps effective. The GDDR6 technology in the NVIDIA card achieves higher effective data rates per pin despite the lower base clock.

Compute throughput numbers show the RTX A1000's theoretical advantage. The AMD card delivers 4.489 TFLOPS of FP32 and the same 4.489 TFLOPS for FP16, a 1:1 ratio. The NVIDIA card delivers 6.737 TFLOPS for both FP32 and FP16, also at 1:1. The RTX A1000's pixel rate is 46.78 GPixel/s versus 35.07 GPixel/s for the AMD card, while the texture rates are 105.3 GTexel/s for NVIDIA versus 140.3 GTexel/s for AMD. The AMD card wins on texture fill rate, reflecting its larger TMU count, but loses on pixel throughput and compute.

The power profiles are starkly different. The Radeon Pro 575X has a TDP of 150 W and is integrated into the Mac as an IGP with no power connectors. The RTX A1000 has a TDP of just 50 W, is a single-slot card with no power connectors, and has a suggested PSU of 250 W. The RTX A1000 also uses a PCIe 4.0 x8 interface, while the Radeon Pro 575X uses PCIe 3.0 x16. The NVIDIA card offers four mini-DisplayPort 1.4a outputs, while the AMD card's display outputs are portable device dependent. The API support differs too: the RTX A1000 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Radeon Pro 575X supports DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The AMD Radeon Pro 575X has an average benchmark score of 39,116, which is higher than the NVIDIA RTX A1000's average of 34,207. However, this aggregate metric does not reflect the head-to-head results, where the RTX A1000 wins both Geekbench tests.

Q: Why does the RTX A1000 win the head-to-head tests despite having a lower average score?

A: The average benchmark score includes a different set of tests across the database. In the specific head-to-head Geekbench OpenCL and Vulkan tests, the RTX A1000 leads by 33.2% and 23.5% respectively. The average score incorporates a broader range of workloads, which can shift relative standings.

Q: How much memory does each card have, and what type?

A: The AMD Radeon Pro 575X has 4 GB of GDDR5 memory on a 256 bit bus with 217.0 GB/s bandwidth. The NVIDIA RTX A1000 has 8 GB of GDDR6 memory on a 128 bit bus with 192.0 GB/s bandwidth.

Q: What are the TDP ratings for these two cards?

A: The AMD Radeon Pro 575X has a TDP of 150 W. The NVIDIA RTX A1000 has a TDP of 50 W, a quarter of the AMD card's power draw.

Q: Does the RTX A1000 support ray tracing?

A: Yes, the RTX A1000 includes 18 ray tracing cores and 72 tensor cores as part of its Ampere architecture. The AMD Radeon Pro 575X has no ray tracing or tensor cores.

Q: What is the production status of each GPU?

A: The AMD Radeon Pro 575X is end-of-life, with a release date of March 2019. The NVIDIA RTX A1000 is active, with a release date of April 2024.

The Verdict

The data points to a clear winner for most workloads: the NVIDIA RTX A1000. In the two direct comparisons available, it beats the AMD Radeon Pro 575X by 33.2% in OpenCL and 23.5% in Vulkan. It offers double the memory capacity at 8 GB versus 4 GB, uses faster GDDR6 memory, and consumes only 50 W compared to 150 W. It brings dedicated ray tracing and tensor cores, supports the newer DirectX 12 Ultimate feature set, and uses a PCIe 4.0 interface. Its smaller die with higher transistor density on a more advanced 8 nm process gives it a modern architectural foundation.

The AMD Radeon Pro 575X does have advantages in specific areas. Its average benchmark score across the database is higher, at 39,116 versus 34,207. It has a wider 256 bit memory bus with higher bandwidth at 217.0 GB/s, and it delivers a higher texture fill rate of 140.3 GTexel/s against the RTX A1000's 105.3 GTexel/s. It also holds a higher percentile ranking at 82 versus 79. For users who prioritize those specific characteristics, the AMD card remains competitive within its peer group, sitting close to the Radeon Pro 580X and the GeForce MX570 A.

However, the head-to-head results are what matter most for direct comparison. The RTX A1000 wins every measured test, and it does so with a fraction of the power draw. The Radeon Pro 575X is an end-of-life product from 2019, while the RTX A1000 is an active product from 2024. For new workstation builds, the RTX A1000 is the stronger choice based on the recorded data. For users already invested in the AMD ecosystem or those who specifically need the higher texture throughput, the Radeon Pro 575X can still serve, but it is an older design with less headroom.
