AMD Radeon Pro Duo vs AMD Radeon RX 7650 GRE Comparison

Head-to-Head Benchmarks

The single recorded head-to-head comparison in the database is the Geekbench OpenCL test, and the result is decisively in favor of the AMD Radeon RX 7650 GRE. The RX 7650 GRE scores 83,109 points, while the AMD Radeon Pro Duo manages 35,860 points. That represents a 131.8% advantage for the newer card, meaning the RX 7650 GRE delivers more than double the OpenCL compute performance of the Pro Duo in this specific workload.

The magnitude of this delta is substantial even when viewed against the broader field. The RX 7650 GRE holds an average benchmark score of 42,723 across all recorded tests, placing it in the 83rd percentile of all GPUs in the database. The Radeon Pro Duo, by contrast, has an average benchmark score of 35,860, which places it in the 80th percentile. While both cards sit in the upper quartile of all GPUs, the RX 7650 GRE's lead in the direct comparison is far larger than the percentile gap might suggest.

The RX 7650 GRE's nearest rivals in the database include the NVIDIA GeForce RTX 4070 SUPER with an average score of 43,223 (a 1.2% delta), the NVIDIA Quadro M6000 24 GB at 43,262 (also 1.2% delta), the NVIDIA GeForce RTX 5050 Mobile at 43,268 (1.3% delta), and the NVIDIA Quadro M6000 at 43,301 (1.3% delta). These deltas are all negative for the RX 7650 GRE, indicating that the card sits just slightly below these competitors in average benchmark performance. The Radeon Pro Duo's nearest rivals include the NVIDIA Quadro GV100 at 35,520 (a 1% positive delta for the Pro Duo), the NVIDIA GeForce RTX 5070 Ti Mobile at 35,435 (1.2% positive), the NVIDIA T1000 at 36,289 (1.2% negative), and the AMD Radeon RX 5300M at 36,529 (1.8% negative). This places the Pro Duo in a competitive band where it is marginally ahead of some workstation-class parts but slightly behind others.

The head-to-head record shows one win for the RX 7650 GRE and zero for the Radeon Pro Duo. This is a clean sweep in the only metric where both cards have recorded data. The absence of other common benchmarks means the comparison rests on this single OpenCL result, but the margin is so large that it establishes a clear performance hierarchy.

Where Each One Wins

The AMD Radeon RX 7650 GRE wins in raw compute throughput, as evidenced by its 131.8% lead in Geekbench OpenCL. This advantage is rooted in its modern architecture and significantly higher clock speeds. The card operates at a base clock of 1720 MHz, a boost clock of 2695 MHz, and a game clock of 2350 MHz. The Radeon Pro Duo has no recorded base, boost, or game clock in the database, which means its operating frequencies are either undisclosed or not applicable to its design. The RX 7650 GRE also has a substantial FP32 compute rating of 22.08 TFLOPS compared to the Pro Duo's 8.192 TFLOPS, a difference that directly explains the OpenCL benchmark outcome.

The Radeon Pro Duo, however, has strengths in specific areas that are not captured by the single head-to-head test. Its memory subsystem is notably different: it features 4 GB of HBM memory on a 4096-bit bus, yielding a bandwidth of 512.0 GB/s. The RX 7650 GRE has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. Despite having half the capacity, the Pro Duo's bandwidth is 77.8% higher, which could benefit memory-bound workloads such as large data transfers or certain compute kernels that are sensitive to memory throughput rather than raw shader output.

The Pro Duo also has a higher raw count of shading units, with 4096 compared to the RX 7650 GRE's 2048, and more texture mapping units, 256 versus 128. Its texture rate is 256.0 GTexel/s against the RX 7650 GRE's 345.0 GTexel/s, meaning the newer card still wins on texture throughput despite having fewer TMUs. The pixel rates tell a similar story: the RX 7650 GRE achieves 172.5 GPixel/s versus the Pro Duo's 64.00 GPixel/s.

For gaming and modern DirectX workloads, the RX 7650 GRE is the clear choice. It supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro Duo is limited to DirectX 12 (12_0) and Vulkan 1.2.170. The RX 7650 GRE also includes 32 ray tracing cores, a feature entirely absent from the Pro Duo. For legacy compute tasks or workloads optimized for GCN architecture, the Pro Duo's higher memory bandwidth and larger shader count might still be relevant, but the recorded data shows no benchmark where it outperforms the RX 7650 GRE.

Architecture Differences

The two cards represent vastly different eras of AMD GPU design. The AMD Radeon RX 7650 GRE is built on the RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is fabricated on a 6 nm process at TSMC. The Radeon Pro Duo uses the older GCN 3.0 architecture with the Capsaicin chip, belonging to the Radeon Pro GCN generation, and is built on a 28 nm process, also at TSMC.

The process node difference is stark: 6 nm versus 28 nm. This allows the RX 7650 GRE to pack 13,300 million transistors into a die size of 204 mm², resulting in a transistor density of 65.2 million per mm². The Pro Duo has 8,900 million transistors on a much larger die of 596 mm², yielding a density of just 14.9 million per mm². The RX 7650 GRE achieves more than four times the transistor density of the Pro Duo, a direct consequence of the manufacturing process advancement.

The memory architectures are fundamentally different. The RX 7650 GRE uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The Pro Duo uses 4 GB of HBM with a 4096-bit bus and 512.0 GB/s bandwidth. The Pro Duo's memory clock is recorded as 500 MHz with 1000 Mbps effective, while the RX 7650 GRE runs its memory at 2250 MHz with 18 Gbps effective. The Pro Duo's wider bus compensates for its lower clock speed, resulting in higher aggregate bandwidth.

The power characteristics differ significantly. The RX 7650 GRE has a TDP of 170 W and requires a single 8-pin power connector with a suggested PSU of 450 W. The Pro Duo has a TDP of 350 W, requires three 8-pin connectors, and needs a suggested PSU of 750 W. Despite drawing more than double the power, the Pro Duo delivers less than half the FP32 compute of the RX 7650 GRE.

The bus interfaces also differ: the RX 7650 GRE uses PCIe 4.0 x8, while the Pro Duo uses PCIe 3.0 x16. Display outputs show the generational gap, with the RX 7650 GRE offering 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Pro Duo offers 1x HDMI 1.4a and 3x DisplayPort 1.2. The RX 7650 GRE supports modern display standards that the Pro Duo cannot.

The production statuses reflect their lifecycles: the RX 7650 GRE is Active, released on February 6, 2025, while the Pro Duo is End-of-life, released on April 25, 2016. The Pro Duo's predecessor is FirePro GCN and its successor is Radeon Pro Polaris. The RX 7650 GRE's predecessor is Navi II and its successor is Navi IV.
