AMD Radeon Pro VII vs NVIDIA RTX A4500 Comparison

The NVIDIA RTX A4500 and AMD Radeon Pro VII are both end-of-life workstation graphics cards, but they represent fundamentally different design philosophies. The RTX A4500, built on NVIDIA's Ampere architecture, and the Radeon Pro VII, based on AMD's GCN 5.1, compete in the same professional segment yet deliver distinct performance profiles. Benchmark data from the Geekbench suite and aggregate scores reveal a clear leader in raw compute, while architectural differences explain why each card might still appeal to specific workloads.

Head-to-Head Benchmarks

The shared benchmark suite consists of two tests: Geekbench OpenCL and Geekbench Vulkan. In both, the NVIDIA RTX A4500 decisively outperforms the AMD Radeon Pro VII. In Geekbench OpenCL, the RTX A4500 scores 141,837 against the Radeon Pro VII's 90,148, a delta of 57.3%. The Vulkan test shows a similar gap: 131,402 for the RTX A4500 versus 87,774 for the Radeon Pro VII, a 49.7% advantage. These are substantial margins, indicating that the RTX A4500 delivers roughly 50–57% higher throughput in these cross-platform compute and graphics workloads.

The aggregate benchmark scores reinforce this pattern. The RTX A4500's average benchmark score is 92,145, while the Radeon Pro VII averages 88,961. The RTX A4500's nearest-rival list places the Radeon Pro VII at a 3.6% deficit, meaning the A4500 holds a modest but consistent lead in overall performance. Both cards sit at the 95th percentile of all GPUs, confirming that they belong to the high-end tier, but the RTX A4500's superiority in every shared test is unambiguous. The RTX A4500 also has a 3DMark Steel Nomad DX12 score of 3,196, though no comparable figure exists for the Radeon Pro VII in the data.

The Verdict

Based strictly on the benchmark results, the NVIDIA RTX A4500 is the superior card for general compute and graphics tasks. It wins both Geekbench tests by wide margins, and its aggregate score is higher by 3.6%. For users prioritizing raw performance in OpenCL or Vulkan workloads, the RTX A4500 is the clear choice. The Radeon Pro VII, while also a high-end card at the 95th percentile, cannot match the RTX A4500 in these metrics.

However, the data does not tell the whole story. The Radeon Pro VII's architectural strengths—such as higher memory bandwidth and higher FP16 throughput—are not reflected in the Geekbench tests. Those who rely on applications that exploit HBM2 memory or half-precision compute might still find the Radeon Pro VII competitive, but the available benchmark evidence points to the RTX A4500 as the stronger all-around performer. The RTX A4500 also offers features like ray tracing and tensor cores, which the Radeon Pro VII lacks entirely, further tilting the verdict toward NVIDIA for modern professional workloads. The Radeon Pro VII had a launch MSRP of 1,899 USD, but that figure does not alter the performance analysis.

Architecture Differences

The two cards diverge sharply at the silicon level. The RTX A4500 uses NVIDIA's GA102 chip on an 8 nm Samsung process, while the Radeon Pro VII employs AMD's Vega 20 on a 7 nm TSMC node. The RTX A4500 packs 28,300 million transistors across a 628 mm² die, yielding a transistor density of 45.1 million per mm². The Radeon Pro VII contains 13,230 million transistors on a 331 mm² die, with a density of 40.0 million per mm². The RTX A4500's larger, denser chip reflects its more complex architecture.

Memory configurations differ significantly. The RTX A4500 offers 20 GB of GDDR6 memory on a 320-bit bus, delivering 640.0 GB/s of bandwidth. The Radeon Pro VII features 16 GB of HBM2 on a 4096-bit bus, achieving 1.02 TB/s—a 59% higher bandwidth figure. However, the RTX A4500 has more memory capacity, which can be critical for large datasets. Clock speeds also differ: the RTX A4500 runs at a base of 1050 MHz and boost of 1650 MHz, while the Radeon Pro VII operates at 1400 MHz base and 1700 MHz boost. Despite lower clocks, the RTX A4500's higher shading unit count (7,168 vs. 3,840) and tensor/RT core complement (224 tensor cores and 56 RT cores vs. none) drive its compute advantage.

Compute throughput numbers underscore the divergence. The RTX A4500 delivers 23.65 TFLOPS of FP32 and an equal 23.65 TFLOPS of FP16 (1:1 ratio). The Radeon Pro VII offers 13.06 TFLOPS FP32 but 26.11 TFLOPS FP16 (2:1 ratio), meaning it has higher half-precision capability. Pixel and texture rates also differ: the RTX A4500 achieves 158.4 GPixel/s and 369.6 GTexel/s, while the Radeon Pro VII posts 108.8 GPixel/s and 408.0 GTexel/s. The Radeon Pro VII's higher texture rate is notable, but the RTX A4500 leads in pixel fill.

Power and physical characteristics vary as well. The RTX A4500 has a TDP of 200 W and requires a single 8-pin power connector, with a suggested PSU of 550 W. The Radeon Pro VII consumes 250 W, needs one 6-pin and one 8-pin connector, and suggests a 600 W PSU. Both are dual-slot cards, but the RTX A4500 is shorter at 267 mm (10.5 inches) versus the Radeon Pro VII's 305 mm (12 inches). Display outputs differ: the RTX A4500 provides four DisplayPort 1.4a ports, while the Radeon Pro VII offers six mini-DisplayPort 1.4a connectors. API support also separates them—the RTX A4500 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the Radeon Pro VII only reaches DirectX 12 (12_1) and Vulkan 1.3. The RTX A4500 launched in November 2021, succeeding Quadro Turing, while the Radeon Pro VII arrived in May 2020, following Radeon Pro Polaris.

Where Each One Wins

The RTX A4500 wins every benchmark in the shared suite, so its advantage is clear in OpenCL and Vulkan compute tasks. Its 23.65 TFLOPS FP32 performance, combined with 56 RT cores and 224 tensor cores, makes it the better choice for workloads that leverage ray tracing, AI acceleration, or modern DirectX 12 Ultimate features. The 20 GB GDDR6 frame buffer provides more capacity for large models and textures, and the lower TDP (200 W vs. 250 W) means less power draw. The RTX A4500's shorter length and single 8-pin power connector also simplify installation in compact chassis.

The Radeon Pro VII, despite losing the benchmarks, retains specific strengths. Its 1.02 TB/s memory bandwidth is substantially higher than the RTX A4500's 640.0 GB/s, which can benefit applications that are heavily memory-latency sensitive. The 26.11 TFLOPS FP16 throughput (2:1 ratio) is also higher than the RTX A4500's 23.65 TFLOPS, making it potentially attractive for half-precision compute. The Radeon Pro VII offers six display outputs versus four, which may suit multi-monitor setups. However, these advantages do not translate into wins in the tested benchmarks, and the lack of RT and tensor cores limits its appeal for modern AI or ray-traced workflows. For users who prioritize raw benchmark performance and feature completeness, the RTX A4500 is the data-backed winner; for those with specific bandwidth or FP16 needs, the Radeon Pro VII remains a niche option.
