AMD Radeon PRO V620 vs AMD Radeon PRO W7700 Comparison

The AMD Radeon PRO V620 and AMD Radeon PRO W7700 represent two distinct generations of AMD’s professional graphics lineup, with the V620 built on the older RDNA 2.0 architecture and the W7700 on the newer RDNA 3.0 design. Benchmark data shows the V620 leading in both recorded Geekbench tests, but the W7700 counters with a significantly newer process node, higher clock speeds, and far superior compute throughput. The following analysis breaks down their architectural differences, head-to-head performance, and which card suits specific workloads based strictly on the provided data.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The AMD Radeon PRO V620 scores 136,472 on average, while the AMD Radeon PRO W7700 scores 118,976. This puts the V620 14.7% ahead in aggregate performance.

Q: How do the two cards compare in the Geekbench OpenCL test?

A: The V620 wins with a score of 128,580 versus the W7700’s 108,245, a delta of 18.8%. This is the largest single-test gap between the two.

Q: Which GPU has better ray tracing hardware?

A: The V620 has 72 ray accelerators, whereas the W7700 has 48. Both support DirectX 12 Ultimate (12_2), but the V620 carries 50% more RT cores.

Q: What is the memory capacity difference?

A: The V620 features 32 GB of GDDR6 memory, double the W7700’s 16 GB. Both use a 256-bit bus, though the W7700 achieves higher bandwidth at 576.0 GB/s versus 512.0 GB/s.

Q: Which card is more power-efficient according to TDP?

A: The W7700 has a 190 W TDP, while the V620 is rated at 300 W. The W7700 also requires a single 8-pin connector and a 450 W power supply, compared to the V620’s dual 8-pin and 700 W recommendation.

Q: Does the W7700 support modern display outputs?

A: Yes, the W7700 has 4x DisplayPort 2.1 outputs. The V620 has no display outputs at all, making it unsuitable for direct monitor connection.

Architecture Differences

The two GPUs are built on different generations of AMD’s RDNA architecture. The V620 uses RDNA 2.0 with the Navi 21 chip, fabricated on TSMC’s 7 nm process. It packs 26,800 million transistors on a 520 mm² die, yielding a transistor density of 51.5 million per mm². In contrast, the W7700 moves to RDNA 3.0 with the Navi 32 chip, codenamed “Wheat Nas,” on TSMC’s 5 nm node. This newer process accommodates 28,100 million transistors on a smaller 346 mm² die, achieving a density of 81.2 million per mm² — a 57.6% improvement in density.

Core counts differ substantially. The V620 features 4,608 shading units, 288 texture mapping units, and 128 raster operations pipelines. The W7700 reduces these to 3,072 shading units, 192 TMUs, and 96 ROPs. Ray tracing hardware also favors the V620, which has 72 RT cores versus the W7700’s 48. Neither card includes tensor cores.

Clock speeds reverse the trend. The W7700 runs at a 1,900 MHz base and 2,600 MHz boost, while the V620 operates at 1,825 MHz base and 2,200 MHz boost. This gives the W7700 a 400 MHz advantage in boost clocks. Memory clocks also favor the W7700, with 2,250 MHz (18 Gbps effective) compared to the V620’s 2,000 MHz (16 Gbps effective). Despite this, the V620’s 32 GB frame buffer doubles the W7700’s 16 GB capacity, though the W7700 counters with 576.0 GB/s bandwidth versus 512.0 GB/s.

Compute performance heavily favors the W7700. The newer card delivers 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1), while the V620 manages 20.28 TFLOPS FP32 and 40.55 TFLOPS FP16. Pixel and texture rates tell a mixed story: the V620 leads in pixel fill rate at 281.6 GPixel/s versus 249.6 GPixel/s, but the W7700 wins in texture rate at 499.2 GTexel/s versus 633.6 GTexel/s — wait, the V620 actually has the higher texture rate at 633.6 GTexel/s. Both cards share PCIe 4.0 x16 interfaces and identical API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Physically, the V620 is larger at 267 mm in length and 50 mm in width, while the W7700 is shorter at 241 mm and thinner (no width listed). The V620 is end-of-life with a 2021 release date, whereas the W7700 launched in 2023 with a launch MSRP of 999 USD.

Head-to-Head Benchmarks

The benchmark results consistently favor the AMD Radeon PRO V620 across both recorded tests. In Geekbench OpenCL, the V620 scores 128,580 against the W7700’s 108,245, representing an 18.8% advantage. This is a substantial margin, indicating that the older RDNA 2.0 card handles general-purpose compute workloads notably better in this specific test. The V620’s higher shading unit count (4,608 vs 3,072) and larger memory pool likely contribute to this result.

The Geekbench Vulkan test shows a narrower but still decisive lead for the V620. It scores 144,364, while the W7700 trails at 129,706, a difference of 11.3%. Vulkan performance typically benefits from raw throughput and driver optimization, and here the V620’s extra RT cores and ROPs appear to provide an edge despite the W7700’s higher clocks and FP32 compute.

The deltaPct values against their nearest rivals contextualize these scores. The V620’s average of 136,472 sits within 0.5% of the AMD Radeon Pro W6800X Duo (135,774), 0.8% of the AMD Radeon PRO W6800 (135,396), 0.9% of the NVIDIA A10M (135,230), and 0.9% of the NVIDIA RTX 4000 Ada Generation (135,218). This places the V620 in a tight cluster of high-end workstation GPUs, where small margins separate the top performers. The W7700’s average of 118,976 is 1.3% ahead of the NVIDIA GB10 (117,393), 1.6% ahead of the NVIDIA RTX 4000 SFF Ada Generation (117,088), 4% ahead of the NVIDIA Tesla V100 SXM2 16 GB (114,395), and 4.4% ahead of the NVIDIA RTX A5500 Mobile (113,944). This suggests the W7700 competes in a lower performance tier, despite its architectural advantages.

The percentile rankings reflect this hierarchy. The V620 sits in the 96th percentile of all GPUs, while the W7700 is in the 95th. Although the V620 wins both head-to-head tests, the W7700’s superior FP32 throughput (31.95 TFLOPS vs 20.28 TFLOPS) and higher memory bandwidth indicate that synthetic benchmarks do not capture all aspects of performance. The V620 leads in wins with 2 to 0, but the W7700’s architectural efficiency could translate to different results in compute-heavy applications not represented in these Geekbench tests.

The Verdict

The data clearly designates the AMD Radeon PRO V620 as the stronger performer in the recorded benchmarks, winning both Geekbench OpenCL and Vulkan tests with double-digit margins. Its 32 GB memory capacity and higher core counts make it suitable for memory-intensive workloads and tasks that leverage massive parallelism. The 96th percentile ranking and close proximity to the Radeon Pro W6800X Duo indicate it belongs to the upper echelon of workstation GPUs, despite being end-of-life.

The AMD Radeon PRO W7700, however, offers compelling advantages for specific use cases. Its 5 nm process node and RDNA 3.0 architecture deliver 31.95 TFLOPS FP32, which is 57.5% higher than the V620’s 20.28 TFLOPS. This suggests superior raw compute capability for tasks that scale with FLOPs, such as certain scientific simulations or machine learning inference. The W7700 also consumes 36.7% less power (190 W vs 300 W), requires a simpler power setup, and provides 4x DisplayPort 2.1 outputs, making it a practical choice for desktop workstations needing direct display connectivity. Its 2023 release date and 999 USD launch MSRP position it as a current-generation product.

For users prioritizing benchmark scores and memory capacity, the V620 is the clear choice based on the data. Its 18.8% OpenCL lead and 11.3% Vulkan lead are substantial, and the 32 GB frame buffer is double the W7700’s. For users who need modern display outputs, lower power consumption, and higher FP32 throughput, the W7700 offers architectural benefits that the benchmarks do not fully reflect. The V620 wins the performance crown in recorded tests, but the W7700’s efficiency and feature set make it the more versatile current product. Given the V620’s end-of-life status, availability may favor the W7700, but the benchmark data unequivocally favors the V620.
