The NVIDIA part lists its predecessor as Quadro Turing-M and successor as Ada-MW, while the AMD part has no recorded predecessor or successor.

The Verdict

The benchmark data points to a clear overall winner: the NVIDIA RTX A1000 Mobile. It wins both recorded head-to-head tests, holds a 22.1% higher average benchmark score (47743 versus 39116), and sits three percentile points higher in the database-wide ranking (85th versus 82nd). For anyone choosing between these two for general compute or graphics workloads, the NVIDIA card is the stronger option in every measured discipline.

That said, the AMD Radeon Pro 575X is not without its own data-backed merits. It offers 217.0 GB/s of memory bandwidth, which is 23.3% higher than the NVIDIA card's 176.0 GB/s, and it has double the texture units (128 versus 64). Its texture rate of 140.3 GTexel/s is nearly double the NVIDIA part's 72.96 GTexel/s. For texture-heavy workloads that scale with fill rate and bandwidth, the AMD card could hold an edge, even if its overall compute scores lag.

The production status of both parts is end-of-life, so neither represents a future-proof investment. The AMD Radeon Pro 575X sits close to its nearest rivals: the Radeon Pro 580X is only 1.1% higher in average score, and the NVIDIA RTX A500 Mobile is just 1.1% higher as well. The NVIDIA RTX A1000 Mobile's nearest rivals are all within 2.5% of its average score, indicating a tightly packed competitive field around that performance tier.

Buyers who prioritize raw compute throughput, modern API support, and higher benchmark scores should choose the NVIDIA RTX A1000 Mobile. Buyers who need maximum memory bandwidth or texture throughput, or who are confined to a platform requiring the AMD part's specific feature set, may still find the Radeon Pro 575X acceptable, but the data shows it is the weaker performer overall.

Head-to-Head Benchmarks

The two recorded head-to-head comparisons both favor the NVIDIA RTX A1000 Mobile, but the margins differ substantially between tests.

In Geekbench OpenCL, the NVIDIA card scores 48703 against 34773 for the AMD Radeon Pro 575X. That is a 40.1% lead, the largest margin in any direct comparison between the two. OpenCL workloads often scale with shading unit efficiency and driver optimization. Both cards have 2048 shading units, so the 40.1% gap reflects architectural efficiency rather than raw unit count. The NVIDIA Ampere architecture delivers 4.669 TFLOPS of FP32 compute, while the AMD GCN 4.0 part delivers 4.489 TFLOPS, a difference of only 4.0% in theoretical peak. The fact that the real-world OpenCL gap is ten times larger than the theoretical peak gap suggests significant driver or scheduling advantages for the NVIDIA architecture.

In Geekbench Vulkan, the NVIDIA card scores 46782 versus 37919, a 23.4% lead. Vulkan is a lower-overhead API that tends to expose architectural differences more directly. The NVIDIA part's support for Vulkan 1.4 versus the AMD part's Vulkan 1.3 may partially explain the gap, but version support alone does not account for a 23.4% performance difference. The NVIDIA card's newer 8 nm process node (versus 14 nm for AMD) likely contributes to better clock behavior under sustained load. The NVIDIA base clock is 630 MHz with a boost of 1140 MHz, while the AMD card has no recorded base or boost clocks in the database, making direct clock comparison impossible.

The NVIDIA card's average benchmark score of 47743 is pulled up by its two strong results. The AMD card's average of 39116 is the mean of three results: 44655 in Geekbench Metal, 34773 in Geekbench OpenCL, and 37919 in Geekbench Vulkan. Interestingly, the AMD card's best result (44655 in Metal) is close to the NVIDIA card's worst result (46782 in Vulkan), but the AMD part's OpenCL score drags its average down significantly. The database records no Metal benchmark for the NVIDIA card, so a direct Metal comparison is unavailable.

The win tally stands at 2 for the NVIDIA RTX A1000 Mobile and 0 for the AMD Radeon Pro 575X in head-to-head tests. No benchmark in the recorded data shows the AMD card ahead.

Specification Differences

The two GPUs differ across nearly every major specification category.

Process and die: The NVIDIA RTX A1000 Mobile uses an 8 nm process at Samsung with 8,700 million transistors on a 200 mm² die, yielding a transistor density of 43.5M per mm². The AMD Radeon Pro 575X uses a 14 nm process at GlobalFoundries with 5,700 million transistors on a 232 mm² die, yielding 24.6M per mm². The NVIDIA chip packs 52.6% more transistors into a 13.8% smaller die.

Memory: Both have 4 GB, but the NVIDIA part uses GDDR6 on a 128-bit bus with 176.0 GB/s bandwidth and 11 Gbps effective speed. The AMD part uses GDDR5 on a 256-bit bus with 217.0 GB/s bandwidth and 6.8 Gbps effective speed. The AMD card has 23.3% more bandwidth despite older memory technology, thanks to its double-width bus.

Compute units: Both have 2048 shading units and 32 ROPs. The NVIDIA part has 64 TMUs, 16 RT cores, and 64 tensor cores. The AMD part has 128 TMUs and no recorded RT or tensor cores. The AMD card has double the texture units, while the NVIDIA card brings dedicated ray tracing and tensor acceleration hardware.

Rates: The NVIDIA part achieves 36.48 GPixel/s pixel rate and 72.96 GTexel/s texture rate. The AMD part achieves 35.07 GPixel/s and 140.3 GTexel/s. The AMD card has a 92.3% higher texture rate but a 4.0% lower pixel rate.

Compute throughput: The NVIDIA part delivers 4.669 TFLOPS in both FP32 and FP16 (1:1 ratio). The AMD part delivers 4.489 TFLOPS in both, also 1:1. The NVIDIA part is 4.0% higher in each.

Architecture Differences

The NVIDIA RTX A1000 Mobile is built on the Ampere architecture using the GA107 chip. Ampere is a modern architecture with dedicated RT cores and tensor cores, hardware features absent from the AMD part. The 16 RT cores provide hardware-accelerated ray tracing, and the 64 tensor cores enable AI-accelerated workloads. The architecture supports DirectX 12 Ultimate, which includes features like ray tracing and variable rate shading, and Vulkan 1.4.

The AMD Radeon Pro 575X uses the GCN 4.0 architecture with the Ellesmere chip. GCN 4.0 is an older design without dedicated ray tracing or tensor hardware. It relies on its large texture unit count (128 TMUs) and wide 256-bit memory bus for performance. The architecture tops out at DirectX 12 (12_0) and Vulkan 1.3, missing the Ultimate feature set.

The process node difference is stark: 8 nm at Samsung for NVIDIA versus 14 nm at GlobalFoundries for AMD. This explains why the NVIDIA chip packs 8,700 million transistors into 200 mm² while the AMD chip fits only 5,700 million into 232 mm². The transistor density advantage (43.5M versus 24.6M per mm²) is a direct consequence of the newer node.

The AMD part has double the TMUs (128 versus 64), which drives its texture rate to 140.3 GTexel/s versus 72.96 GTexel/s. However, the NVIDIA part compensates with higher clock behavior and modern scheduling. The NVIDIA base clock is 630 MHz with a boost of 1140 MHz; the AMD card has no recorded clocks, so its operating frequencies remain undocumented in the database.

The memory architecture reflects the era of each design. The AMD card uses GDDR5 at 6.8 Gbps effective on a 256-bit bus. The NVIDIA card uses GDDR6 at 11 Gbps effective on a 128-bit bus. The AMD card wins on bandwidth (217.0 versus 176.0 GB/s), but the NVIDIA card's newer memory type operates at 61.8% higher effective speed.

Both parts are end-of-life, but the NVIDIA card has a recorded successor (Ada-MW) and predecessor (Quadro Turing-M). The AMD card has neither, suggesting it was a terminal product in its line.

• FP32 and FP16 compute: 4.669 TFLOPS versus 4.489 TFLOPS.
• Pixel rate: 36.48 versus 35.07 GPixel/s.
• PCIe generation: PCIe 4.0 versus 3.0.
• Percentile ranking: 85th versus 82nd.

AMD Radeon Pro 575X wins on:

• Memory bandwidth: 217.0 GB/s versus 176.0 GB/s, a 23.3% advantage.
• Texture rate: 140.3 GTexel/s versus 72.96 GTexel/s, a 92.3% advantage.
• Texture unit count: 128 versus 64.
• Memory bus width: 256-bit versus 128-bit.
• Die size: 232 mm² versus 200 mm² (larger, though less dense).
• Metal benchmark: the database records a 44655 Metal score for the AMD part, with no Metal result for the NVIDIA card.

The use-case split follows the data. The NVIDIA card is the better choice for general compute, modern API workloads, ray tracing, AI acceleration, and any scenario where power draw matters. The AMD card could be preferable for texture-heavy workloads that saturate its double texture rate and higher memory bandwidth, such as certain older game engines or texture-bound rendering tasks. The AMD card's Metal score of 44655 suggests it may hold up reasonably in macOS-specific workloads, though the database does not provide a direct NVIDIA comparison in that API. For everything else, the NVIDIA RTX A1000 Mobile is the data-backed pick.
