AMD Radeon PRO W7900 vs AMD Radeon VII Comparison

AMD Radeon PRO W7900 vs AMD Radeon VII

The benchmark database records only two head-to-head tests for these GPUs, and each card claims one victory. The AMD Radeon VII wins the Geekbench OpenCL test with a score of 91,947 against the PRO W7900's 84,379, a lead of 8.2 percent. The AMD Radeon PRO W7900 responds decisively in Geekbench Vulkan, scoring 137,070 versus 91,788, a massive 49.3 percent advantage. The overall average benchmark score reflects this split: the PRO W7900 averages 110,725 across all recorded tests, while the Radeon VII averages 66,004. The data shows two very different performance profiles, one built for compute-style workloads and the other for modern graphics APIs.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the Radeon VII's strongest showing. Its score of 91,947 exceeds the PRO W7900's 84,379, meaning the older card outperforms the newer workstation flagship by 8.2 percent in this specific test. This is notable because the Radeon VII relies on GCN 5.1 architecture with 3,840 shading units, while the PRO W7900 uses RDNA 3.0 with 6,144 shading units. The OpenCL result suggests that raw shader count does not automatically translate to higher compute scores, at least in this benchmark configuration.

The Geekbench Vulkan test tells the opposite story. The PRO W7900 scores 137,070, which is 49.3 percent higher than the Radeon VII's 91,788. This gap is far larger than the OpenCL difference and indicates a substantial architectural advantage for the newer card in modern graphics workloads. Vulkan is a low-level API that benefits from the RDNA 3.0 design, including its dedicated ray tracing cores and updated scheduling. The Radeon VII, lacking those features, cannot keep pace.

Looking at broader database context, the PRO W7900 sits at the 94th percentile among all GPUs, while the Radeon VII sits at the 90th percentile. The average benchmark score difference is substantial: 110,725 for the PRO W7900 versus 66,004 for the Radeon VII, a gap of approximately 67.8 percent. The PRO W7900's nearest rivals in the database include the AMD Radeon Pro Vega II at an average score of 109,617 (1 percent lower), the NVIDIA RTX A5500 Mobile at 113,944 (2.8 percent higher), the AMD Radeon Pro W6600X at 107,342 (3.2 percent lower), and the NVIDIA Tesla V100 SXM2 16 GB at 114,395 (3.2 percent higher). This places the PRO W7900 in a competitive band with high-end workstation and data-center cards.

The Radeon VII's nearest rivals are quite different in character. The NVIDIA Tesla T4 scores 66,733 (1.1 percent lower), the NVIDIA Tesla P40 scores 65,095 (1.4 percent higher), the AMD Radeon Pro WX 9100 scores 64,212 (2.8 percent higher), and the NVIDIA CMP 30HX scores 63,842 (3.4 percent higher). These are much lower-tier products, reflecting the Radeon VII's age and its end-of-life production status.

The Verdict

The data supports a clear recommendation for the AMD Radeon PRO W7900 for anyone prioritizing modern graphics performance, workstation reliability, or long-term software support. Its Vulkan score of 137,070 is nearly 50 percent higher than the Radeon VII, and its average benchmark score of 110,725 is almost double. The PRO W7900 also carries active production status, a 5 nm process node, and support for DirectX 12 Ultimate, Vulkan 1.4, and DisplayPort 2.1. These are current-generation features that the Radeon VII cannot offer.

The AMD Radeon VII remains relevant only for specific compute scenarios where OpenCL performance matters more than Vulkan or modern API support. Its OpenCL win of 8.2 percent is real, but it comes with trade-offs: 16 GB of HBM2 memory versus 48 GB of GDDR6, a 4096-bit bus versus 384-bit, and GCN 5.1 architecture without ray tracing. The Radeon VII is also marked end-of-life, meaning no active driver development or production support.

For a professional workstation user, the choice is unambiguous. The PRO W7900's higher average benchmark score, better Vulkan performance, larger memory pool, and active status make it the superior option. The Radeon VII's single OpenCL victory does not compensate for its lower overall scores, older architecture, and discontinued status. Anyone considering the Radeon VII today should look at the recorded data and recognize that its strengths are narrow and its weaknesses broad.

Architecture Differences

The two cards come from different eras of AMD GPU design. The Radeon PRO W7900 uses the Navi 31 chip on the RDNA 3.0 architecture, codenamed Plum Bonito, manufactured on TSMC's 5 nm process. It packs 57,700 million transistors into a 529 mm² die, giving a transistor density of 109.1 million per square millimeter. The Radeon VII uses the Vega 20 chip on GCN 5.1, built on TSMC's 7 nm process, with 13,230 million transistors on a 331 mm² die and a density of 40.0 million per square millimeter. The newer card has over four times the transistor count on a larger die with a much tighter packing density.

The memory subsystems differ fundamentally. The PRO W7900 uses 48 GB of GDDR6 on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The Radeon VII uses 16 GB of HBM2 on a 4096-bit bus, achieving 1.02 TB/s. While the Radeon VII has higher raw bandwidth, the PRO W7900 has three times the capacity, which matters more for large datasets and modern workloads.

Compute resources also diverge sharply. The PRO W7900 has 6,144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The Radeon VII has 3,840 shading units, 240 TMUs, and 64 ROPs, with no ray tracing cores at all. The PRO W7900's pixel rate is 479.0 GPixel/s versus 112.0 GPixel/s for the Radeon VII. Texture rate is 958.1 GTexel/s versus 420.0 GTexel/s. FP32 throughput is 61.32 TFLOPS versus 13.44 TFLOPS. The FP16 rates are 61.32 TFLOPS (1:1) for the PRO W7900 and 26.88 TFLOPS (2:1) for the Radeon VII, showing the newer card handles FP16 at full rate while the older one halves its throughput.

Clock speeds reflect the process node advantage. The PRO W7900 runs at a base of 1760 MHz and boosts to 2495 MHz. The Radeon VII runs at 1400 MHz base and 1750 MHz boost. Memory clocks are 2250 MHz (18 Gbps effective) for the PRO W7900 versus 1000 MHz (2 Gbps effective) for the Radeon VII.

API support shows the generation gap. The PRO W7900 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon VII supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The PRO W7900 also has DisplayPort 2.1 outputs (three DisplayPort 2.1 and one mini-DisplayPort 2.1), while the Radeon VII has one HDMI 2.0b and three DisplayPort 1.4a. The bus interface is PCIe 4.0 x16 on the PRO W7900 versus PCIe 3.0 x16 on the Radeon VII.

Where Each One Wins

The AMD Radeon VII wins in the OpenCL compute test, a result that may appeal to users running legacy compute kernels or applications optimized for GCN architecture. Its HBM2 memory provides 1.02 TB/s of bandwidth, which is higher than the PRO W7900's 864.0 GB/s, though capacity is much lower at 16 GB versus 48 GB. The Radeon VII also uses a dual-slot design with a smaller footprint, measuring 280 mm in length, 125 mm in height, and 40 mm in width, versus the PRO W7900's triple-slot 280 mm by 110 mm by 51 mm. For users constrained by slot width, the Radeon VII fits more chassis.

The AMD Radeon PRO W7900 wins in every other measurable category. Its Vulkan score is 49.3 percent higher, its average benchmark score is roughly 67.8 percent higher, and it sits at the 94th percentile versus the Radeon VII's 90th. It has more shading units, more TMUs, more ROPs, ray tracing cores, higher pixel and texture rates, higher FP32 and FP16 throughput, and a larger memory pool. It supports newer APIs and display outputs, runs on PCIe 4.0, and remains in active production. For any workload that uses Vulkan, DirectX 12 Ultimate, or large memory buffers, the PRO W7900 is the clear choice.
