AMD Radeon PRO W7900D vs AMD Radeon RX 7650 GRE Comparison

The Verdict

The AMD Radeon PRO W7900D and AMD Radeon RX 7650 GRE serve entirely different segments of the GPU market. The database shows the W7900D as a professional workstation card with 48 GB of memory, while the RX 7650 GRE is a mainstream consumer part with 8 GB. There is no head-to-head benchmark data recorded between the two, and the W7900D has no benchmark scores or rival comparisons in the database. The RX 7650 GRE, by contrast, holds an 83rd percentile ranking among all GPUs, with an average benchmark score of 42,723.

For users requiring massive memory capacity, the W7900D is the only choice between these two, as its 48 GB frame buffer is six times larger than the RX 7650 GRE's 8 GB. The professional card also delivers substantially higher compute throughput, with FP32 performance of 52.99 TFLOPS versus 22.08 TFLOPS on the consumer card. The RX 7650 GRE, however, is the more efficient and compact option, with a 170 W TDP versus 295 W, dual-slot cooling versus triple-slot, and a single 8-pin power connector versus two 8-pin connectors.

The data indicates that the RX 7650 GRE is positioned for mainstream gaming and general desktop use, while the W7900D targets workstation workloads that demand large memory pools and professional display outputs. The W7900D offers three DisplayPort 2.1 outputs plus a mini-DisplayPort 2.1, while the RX 7650 GRE provides one HDMI 2.1a and three DisplayPort 2.1 outputs. This suggests the W7900D is designed around multi-display professional setups, whereas the RX 7650 GRE accommodates consumer displays including televisions via HDMI.

Architecture Differences

Both GPUs share the RDNA 3.0 architecture, but they are built on different process nodes and use entirely different chips. The W7900D uses the Navi 31 chip, fabricated on TSMC's 5 nm process, while the RX 7650 GRE uses the Navi 33 chip on a 6 nm process. The codenames differ as well: Plum Bonito for the W7900D and Hotpink Bonefish for the RX 7650 GRE.

The transistor counts reveal the scale gap. The W7900D packs 57,700 million transistors on a 529 mm² die, resulting in a transistor density of 109.1 million per square millimeter. The RX 7650 GRE contains 13,300 million transistors on a 204 mm² die, with a density of 65.2 million per square millimeter. This means the W7900D has over four times the transistor count and a die more than 2.5 times larger.

Core configurations differ dramatically. The W7900D features 6,144 shading units, 384 texture mapping units, 192 raster operations units, and 96 ray tracing cores. The RX 7650 GRE has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The W7900D therefore provides three times the shading units, TMUs, and ROPs, and three times the ray tracing cores.

Both cards use GDDR6 memory, but the memory subsystem is completely different. The W7900D has a 384-bit memory bus with 864.0 GB/s bandwidth, while the RX 7650 GRE uses a 128-bit bus with 288.0 GB/s bandwidth. Memory clock is identical at 2250 MHz with 18 Gbps effective, but the wider bus on the W7900D delivers three times the bandwidth.

API support is identical across both cards: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither card has tensor cores recorded in the database. Both are listed as Active production status.

Power and physical specifications differ as well: 295 W versus 170 W TDP, triple-slot versus dual-slot, two 8-pin versus one 8-pin power connector, and 600 W versus 450 W suggested PSU. The W7900D measures 280 mm by 110 mm by 51 mm, while the RX 7650 GRE measures 204 mm by 115 mm with no width recorded. Bus interface is PCIe 4.0 x16 for the W7900D and PCIe 4.0 x8 for the RX 7650 GRE. The RX 7650 GRE carries a launch MSRP of 279 USD.

The W7900D was released on September 24, 2025, while the RX 7650 GRE was released on February 6, 2025. The W7900D lists the Radeon Pro Vega as its predecessor with no successor recorded, while the RX 7650 GRE lists Navi II as predecessor and Navi IV as successor. The W7900D belongs to the Radeon Pro Navi (Navi III Series) generation, while the RX 7650 GRE belongs to the Navi III (RX 7000) series.

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist in the database for these two cards. The wins count is zero for both, and no shared tests have been recorded. This reflects the fundamentally different positioning of the two products, as the W7900D has no benchmark entries at all while the RX 7650 GRE has two recorded tests.

The RX 7650 GRE's benchmark data provides some context. In 3DMark Steel Nomad DX12, it scores 2,336, and in Geekbench OpenCL it scores 83,109. Its average benchmark score across all recorded tests is 42,723. The nearest rivals in the database are all NVIDIA products, with the RTX 4070 SUPER and Quadro M6000 24 GB both sitting 1.2% ahead, and the RTX 5050 Mobile and Quadro M6000 both 1.3% ahead.

The W7900D's compute advantages are clear from the specification data, even without benchmark scores. Its FP32 throughput of 52.99 TFLOPS is 2.4 times the RX 7650 GRE's 22.08 TFLOPS. Pixel throughput is 2.4 times higher, and texture throughput is also 2.4 times higher. Memory bandwidth of 864.0 GB/s is exactly three times the RX 7650 GRE's 288.0 GB/s.

The RX 7650 GRE counters with higher clock speeds and better efficiency metrics. Its boost clock of 2695 MHz is 25% higher than the W7900D's 2156 MHz. Its TDP of 170 W is 125 W lower than the W7900D's 295 W, meaning the consumer card delivers its 22.08 TFLOPS at 58% of the power draw. The RX 7650 GRE also fits in a dual-slot form factor with a single 8-pin connector, compared to the W7900D's triple-slot design with two 8-pin connectors.

The percentile data further separates the cards. The RX 7650 GRE ranks at the 83rd percentile among all GPUs, while the W7900D sits at the 50th percentile with an average benchmark score of zero. This discrepancy stems from the absence of recorded benchmarks for the W7900D rather than an indication of real-world performance, as the W7900D's specification sheet shows substantially higher compute and memory capabilities.

Release timing shows the RX 7650 GRE arrived first in February 2025, followed by the W7900D in September 2025. Both remain in Active production status. The RX 7650 GRE has a recorded successor, Navi IV, while the W7900D's successor field is empty.

In practical terms, the W7900D dominates in raw throughput and memory capacity, making it suitable for large datasets and professional rendering workloads. The RX 7650 GRE offers higher clock speeds, lower power draw, and a smaller physical footprint, making it appropriate for standard desktop systems with limited space and power budget. The two cards do not compete in the same market segment, and the database contains no common benchmarks to compare them directly.
