AMD Radeon PRO W7900 vs AMD Radeon RX 7650 GRE Comparison

Head-to-Head Benchmarks

The database contains a single direct head-to-head benchmark between these two AMD graphics cards, and the result is close. In the Geekbench OpenCL test, the AMD Radeon PRO W7900 scores 84,379, while the AMD Radeon RX 7650 GRE scores 83,109. That gives the PRO W7900 a 1.5% advantage, a narrow margin that places the two cards nearly on par in raw compute workloads. The 1.5% delta is small enough that run-to-run variance could plausibly close the gap, but the recorded result still favors the workstation card.

The larger picture emerges when comparing each card against its own nearest rivals. The AMD Radeon PRO W7900 holds an average benchmark score of 110,725 across all recorded tests, which places it in the 94th percentile of all GPUs in the database. Its nearest rival, the AMD Radeon Pro Vega II, averages 109,617, a delta of 1% in favor of the W7900. Against the NVIDIA RTX A5500 Mobile, which averages 113,944, the W7900 trails by 2.8%. It also sits 3.2% ahead of the AMD Radeon Pro W6600X (107,342) and 3.2% behind the NVIDIA Tesla V100 SXM2 16 GB (114,395). These results indicate the W7900 operates in a tight cluster of high-end workstation and datacenter parts, with no single rival dominating by more than 3.2%.

The AMD Radeon RX 7650 GRE, by contrast, averages 42,723 across all recorded tests, placing it in the 83rd percentile. Its nearest rivals cluster extremely close: the NVIDIA GeForce RTX 4070 SUPER averages 43,223 (1.2% ahead), the NVIDIA Quadro M6000 24 GB averages 43,262 (1.2% ahead), the NVIDIA GeForce RTX 5050 Mobile averages 43,268 (1.3% ahead), and the NVIDIA Quadro M6000 averages 43,301 (1.3% ahead). The RX 7650 GRE is therefore the weakest of its five-card comparison group, but only by a narrow margin. Its individual Geekbench OpenCL score of 83,109 is remarkably close to the W7900’s 84,379, even though the two cards sit in very different performance classes overall.

The discrepancy between the direct OpenCL result and the average benchmark scores stems from the specific workloads captured. The W7900’s average score of 110,725 is heavily influenced by its Geekbench Vulkan result of 137,070, a test the RX 7650 GRE has no recorded entry for. The RX 7650 GRE’s database entry includes a 3DMark Steel Nomad DX12 score of 2,336, a workload the W7900 lacks. Each card therefore shows strength in the tests it was subjected to, and the single shared workload, Geekbench OpenCL, shows only a 1.5% separation.

Where Each One Wins

The AMD Radeon PRO W7900 wins the only direct comparison in the database, the Geekbench OpenCL test, by 1.5%. More significantly, it outclasses the RX 7650 GRE in nearly every hardware specification recorded. The W7900 uses the Navi 31 chip with 6,144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The RX 7650 GRE uses the Navi 33 chip with 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The W7900 delivers 61.32 TFLOPS of FP32 performance and 61.32 TFLOPS of FP16 performance, while the RX 7650 GRE delivers 22.08 TFLOPS in both. Pixel throughput stands at 479.0 GPixel/s for the W7900 versus 172.5 GPixel/s for the RX 7650 GRE, and texture throughput is 958.1 GTexel/s versus 345.0 GTexel/s.

Memory capacity and bandwidth also favor the W7900 decisively. The W7900 carries 48 GB of GDDR6 memory on a 384-bit bus, yielding 864.0 GB/s of bandwidth. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s. That is a 3x advantage in bandwidth and a 6x advantage in capacity. The W7900’s 57,700 million transistors on a 529 mm² die dwarf the RX 7650 GRE’s 13,300 million transistors on a 204 mm² die. The process node differs as well: the W7900 uses TSMC’s 5 nm process, while the RX 7650 GRE uses TSMC’s 6 nm process.

The RX 7650 GRE does hold some advantages in the recorded data. Its boost clock of 2695 MHz is higher than the W7900’s 2495 MHz, and its base clock of 1720 MHz edges out the W7900’s 1760 MHz base by a small margin. The RX 7650 GRE also lists a game clock of 2350 MHz, a field that is null for the W7900. The power draw is substantially lower: 170 W TDP versus 295 W, and the RX 7650 GRE requires a single 8-pin connector and a 450 W suggested PSU, while the W7900 needs two 8-pin connectors and a 600 W suggested PSU. The RX 7650 GRE is also a dual-slot card at 204 mm length, whereas the W7900 is a triple-slot card at 280 mm length.

The RX 7650 GRE’s 3DMark Steel Nomad DX12 score of 2,336 has no counterpart in the W7900’s database entry, so it stands as the card’s only exclusive benchmark win. Its Geekbench OpenCL score of 83,109 is only 1.5% behind the W7900, which is a strong showing for a card with roughly one-third the shading units and one-third the memory bandwidth.

The Verdict

The database’s recorded measurements indicate two different design goals. The AMD Radeon PRO W7900 is positioned for maximum compute throughput, memory capacity, and bandwidth. Its 48 GB of GDDR6, 864.0 GB/s of bandwidth, and 61.32 TFLOPS of FP32 performance are far beyond anything the RX 7650 GRE can offer. Its 94th percentile ranking among all GPUs and its tight rivalry with datacenter cards like the NVIDIA Tesla V100 SXM2 16 GB and NVIDIA RTX A5500 Mobile confirm its placement in the high-end segment.

The AMD Radeon RX 7650 GRE is a lighter, lower-power card. Its 170 W TDP, dual-slot design, and single 8-pin power connector make it far easier to integrate into compact systems. Its 83rd percentile ranking places it well below the W7900, but its nearest rivals are all within 1.3%, indicating it competes effectively in its own class. The Geekbench OpenCL result, showing only a 1.5% gap to the W7900, suggests that in compute-heavy but memory-light tasks, the RX 7650 GRE is surprisingly competitive despite its smaller hardware footprint.

Who should pick which, strictly from the data: users who need 48 GB of memory, triple-digit GPixel/s pixel rates, and workstation-class throughput should choose the AMD Radeon PRO W7900. Users who prioritize lower power draw, a smaller physical footprint, and a lower launch MSRP should choose the AMD Radeon RX 7650 GRE. The RX 7650 GRE’s launch MSRP was 279 USD, while the W7900’s launch MSRP was 3,999 USD.
