AMD Radeon Pro Vega 64 vs NVIDIA RTX A1000 Mobile Comparison

The Verdict

The data is unambiguous: the AMD Radeon Pro Vega 64 is the faster GPU by a wide margin in both recorded benchmarks. Its average benchmark score of 72,379 places it at the 91st percentile of all GPUs, while the NVIDIA RTX A1000 Mobile averages 47,743, sitting at the 85th percentile. In the two shared tests, the Radeon Pro Vega 64 wins both, with a 46% lead in Geekbench OpenCL and a 58.6% lead in Geekbench Vulkan. There are zero recorded wins for the RTX A1000 Mobile.

However, the choice between them is not about raw speed alone. The Radeon Pro Vega 64 is an integrated graphics processor from 2017, built on a 14 nm process with a 250 W TDP, and its display outputs are portable-device dependent. The RTX A1000 Mobile is a 2022 part on an 8 nm process, drawing 60 W, with 16 dedicated ray tracing cores and 64 tensor cores. Anyone selecting between these should ask what they actually need: maximum compute throughput in legacy APIs, or modern feature support with dramatically lower power draw.

For raw performance, the AMD Radeon Pro Vega 64 is the only logical pick. For a mobile workstation where power efficiency, ray tracing hardware, and modern API compliance matter more than raw Geekbench scores, the RTX A1000 Mobile is the defensible choice. The benchmark database shows no scenario where the NVIDIA part wins a recorded test, so if performance is the sole criterion, the decision is already made.

Where Each One Wins

The AMD Radeon Pro Vega 64 wins every benchmark category recorded in the database. In Geekbench OpenCL, it scores 71,094 against 48,703 for the RTX A1000 Mobile, a 46% advantage. In Geekbench Vulkan, it scores 74,174 against 46,782, a 58.6% advantage. These are not narrow margins; they are substantial, consistent leads across two different compute APIs.

The RTX A1000 Mobile does not win any recorded benchmark. Its strengths lie outside the measured tests. It has 16 ray tracing cores and 64 tensor cores, hardware the AMD part lacks entirely. It supports DirectX 12 Ultimate (12_2), whereas the Radeon Pro Vega 64 supports DirectX 12 (12_1). It also supports Vulkan 1.4, one full revision ahead of the Radeon's Vulkan 1.3. In workloads that use those features, such as ray-traced rendering or AI inference, the NVIDIA part has architectural capabilities the AMD part cannot match, even if those capabilities do not show up in the Geekbench scores recorded here.

The power envelope also separates them. The RTX A1000 Mobile is rated at 60 W TDP, the Radeon Pro Vega 64 at 250 W. In thermally constrained portable chassis, that difference can be decisive. The AMD part is an IGP (integrated graphics processor) with no power connectors and a PCIe 3.0 x16 interface; the NVIDIA part is also an IGP with no power connectors but uses PCIe 4.0 x8. The RTX A1000 Mobile is the more practical choice for a thin, battery-powered laptop, while the Radeon Pro Vega 64 is a performance-first part that assumes the host system can feed and cool it.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The AMD Radeon Pro Vega 64 uses the Vega 10 chip on GCN 5.0 architecture, fabricated by GlobalFoundries on a 14 nm process. It packs 12,500 million transistors into a 495 mm² die, yielding a transistor density of 25.3 million per square millimeter. The NVIDIA RTX A1000 Mobile uses the GA107 chip on Ampere architecture, fabricated by Samsung on an 8 nm process. It contains 8,700 million transistors on a 200 mm² die, with a much higher density of 43.5 million per square millimeter.

The compute resources differ sharply. The Radeon Pro Vega 64 has 4,096 shading units, 256 texture mapping units, and 64 render output units. The RTX A1000 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs, exactly half in shading units and ROPs, and a quarter in TMUs. The AMD part also has no ray tracing or tensor cores, while the NVIDIA part has 16 RT cores and 64 tensor cores.

Memory configurations are radically different. The AMD GPU uses 16 GB of HBM2 on a 2048-bit bus, delivering 402.4 GB/s of bandwidth. The NVIDIA GPU uses 4 GB of GDDR6 on a 128-bit bus, delivering 176.0 GB/s. The AMD part has four times the capacity and more than twice the bandwidth. Clock speeds also differ, with the AMD part running at 1250 MHz base and 1350 MHz boost, versus 630 MHz base and 1140 MHz boost for the NVIDIA part. The AMD memory runs at 786 MHz (1572 Mbps effective), while the NVIDIA memory runs at 1375 MHz (11 Gbps effective).

The rated throughput figures reflect the hardware disparity. The Radeon Pro Vega 64 reaches 11.06 TFLOPS FP32 and 22.12 TFLOPS FP16 (2:1 ratio). The RTX A1000 Mobile reaches 4.669 TFLOPS FP32 and 4.669 TFLOPS FP16 (1:1 ratio). Pixel rates are 86.40 GPixel/s versus 36.48 GPixel/s, and texture rates are 345.6 GTexel/s versus 72.96 GTexel/s. The AMD part is faster in every raw throughput metric, but the NVIDIA part maintains full FP16 rate, meaning it does not need to halve throughput for half-precision work.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows a 46% win for the AMD Radeon Pro Vega 64. The AMD part scores 71,094 against 48,703 for the NVIDIA RTX A1000 Mobile. In terms of context, the AMD part sits 0.4% above the NVIDIA TITAN X Pascal (72,098 average score, -0.4% delta from the AMD average of 72,379, meaning the TITAN is 0.4% lower, and the AMD Radeon RX 6650M is 0.9% lower at 71,768; the AMD Radeon Vega Frontier Edition is 1.4% higher at 73,370). The RTX A1000 Mobile, by contrast, sits 1.5% below the AMD Radeon RX 6800 XT (48,477 average) and 2.2% above the AMD Radeon RX 6550M (46,702 average). This puts the two GPUs in completely different performance tiers, with the Radeon Pro Vega 64 competing against desktop-class parts and the RTX A1000 Mobile competing against mid-range mobile parts.

The Geekbench Vulkan test is even more lopsided. The AMD Radeon Pro Vega 64 scores 74,174, which is 58.6% higher than the RTX A1000 Mobile's 46,782. This is the largest recorded delta in the head-to-head data. The Vulkan result suggests the AMD architecture scales particularly well in this API, possibly due to its much wider memory bus and higher raw shading throughput. The NVIDIA part's Vulkan score is actually lower than its OpenCL score, while the AMD part's Vulkan score is higher than its OpenCL score, widening the gap further.

The AMD part's average benchmark score of 72,379 places it at the 91st percentile of all GPUs, meaning it outperforms roughly nine out of ten GPUs in the database. The RTX A1000 Mobile's average of 47,743 places it at the 85th percentile. Despite the large raw score difference, both are above the median, but the AMD part sits in a clearly higher performance band. The recorded data shows a consistent pattern: the Radeon Pro Vega 64 leads by roughly half in OpenCL and by nearly three-fifths in Vulkan, with no recorded test favoring the NVIDIA part.

The two GPUs share some traits: both are integrated graphics processors with no power connectors, portable-device-dependent display outputs, no suggested PSU, and no dimensions recorded. Both support OpenGL 4.6. Both are end-of-life products. But the differences dominate, from process technology and transistor counts to memory systems, compute resources, and API support. The Radeon Pro Vega 64 is a high-power, high-throughput part from 2017; the RTX A1000 Mobile is a low-power, feature-rich part from 2022. The benchmark data shows one is much faster, while the specification sheet shows the other is much more modern.
