AMD Radeon Pro 575 vs AMD Radeon RX 7650 GRE Comparison

AMD Radeon RX 7650 GRE decisively outperforms the AMD Radeon Pro 575 in the only directly comparable benchmark, with the data showing a 140.2% advantage for the newer card. The RX 7650 GRE scores 83,109 in Geekbench OpenCL, while the Radeon Pro 575 manages only 34,596, a gap that positions these GPUs in entirely different performance tiers despite their near-identical average benchmark scores (42,723 vs 39,555).

Head-to-Head Benchmarks

The single head-to-head comparison available in the data is Geekbench OpenCL, and the result is emphatic. The AMD Radeon RX 7650 GRE posts 83,109 points against the AMD Radeon Pro 575's 34,596 points, yielding a delta of 140.2% in favor of the RX 7650 GRE. This is not a marginal victory; the newer card more than doubles the compute output of the older Pro model in this OpenCL workload.

Context from the nearest rival data reinforces the magnitude of this gap. The RX 7650 GRE's average benchmark score of 42,723 places it within 1.2% of the NVIDIA GeForce RTX 4070 SUPER (43,223) and the NVIDIA Quadro M6000 24 GB (43,262). Meanwhile, the Radeon Pro 575's average score of 39,555 sits just 0.0% away from the NVIDIA RTX A500 Mobile (39,568). In practical terms, the RX 7650 GRE is competing with modern high-end desktop cards, while the Pro 575 is bracketed by mobile and pro workstation parts from a different era.

The percentile rankings tell a similar story. The RX 7650 GRE sits at the 83rd percentile among all GPUs, while the Radeon Pro 575 is at the 82nd percentile. Despite this near-parity in percentile ranking, the raw OpenCL score difference is stark because the percentile metric aggregates across many different benchmark types, including Metal and Vulkan tests where the older card has relative strengths.

It is importantly the Radeon Pro 575 has additional benchmark data that the RX 7650 GRE lacks: a Geekbench Metal score of 46,192 and a Geekbench Vulkan score of 37,878. These scores are lower than its OpenCL result of 34,596 in absolute terms for Vulkan, but the Metal score is notably higher than its OpenCL figure, suggesting the architecture handles Apple's graphics API with relatively better efficiency. However, no direct comparison exists for these tests against the RX 7650 GRE, so the head-to-head winner remains clear.

Where Each One Wins

The AMD Radeon RX 7650 GRE wins the only direct benchmark comparison, but the data also reveals where each card has distinct advantages in the broader benchmark landscape.

The RX 7650 GRE dominates in raw compute throughput. Its 22.08 TFLOPS FP32 performance is nearly five times the Radeon Pro 575's 4.489 TFLOPS. This translates directly to the OpenCL victory, where the newer card's RDNA 3.0 architecture with 2,048 shading units, 128 TMUs, and 64 ROPs at a boost clock of 2695 MHz simply overwhelms the older GCN 4.0 design. The RX 7650 GRE also has a significant memory bandwidth advantage at 288.0 GB/s over the Pro 575's 217.0 GB/s, despite the older card having a wider 256-bit bus versus the newer card's 128-bit bus. The RX 7650 GRE compensates for its narrower bus with faster GDDR6 memory running at 18 Gbps effective, versus the Pro 575's GDDR5 at 6.8 Gbps effective.

The Radeon Pro 575's wins are more subtle and situational. It has a higher pixel rate per watt when considering its TDP of 150 W versus the RX 7650 GRE's 170 W, though the absolute pixel rate of 35.07 GPixel/s is far lower than the RX 7650 GRE's 172.5 GPixel/s. The Pro 575 also has the advantage of a PCIe 3.0 x16 interface versus the RX 7650 GRE's PCIe 4.0 x8, though the newer standard's higher bandwidth per lane means the RX 7650 GRE still has more total bandwidth available. In terms of form factor, the Pro 575's MXM Module design is suited for portable devices with no external power connectors, while the RX 7650 GRE requires a dual-slot cooler with a single 8-pin connector and a 450 W suggested PSU. For systems with strict power delivery constraints, the Pro 575's "None" power connector requirement is a clear advantage.

The Verdict

The data is unambiguous: choose the AMD Radeon RX 7650 GRE for virtually any compute-focused workload. The 140.2% OpenCL advantage is the single most important datapoint, and it is supported by the massive architectural generational leap. The RX 7650 GRE's 13,300 million transistors on a 6 nm TSMC process versus the Pro 575's 5,700 million transistors on a 14 nm GlobalFoundries process explains the performance chasm. The newer card also has double the memory capacity at 8 GB versus 4 GB, and it is an active production part with a launch MSRP of 279 USD, while the Pro 575 is end-of-life with no listed MSRP.

Pick the AMD Radeon Pro 575 only if the MXM Module form factor is a hard requirement. The data shows it is the only physically viable option for portable devices with no external power connectors. Its 82nd percentile ranking is respectable, and its Metal score of 46,192 indicates it handles Apple-centric workloads competently, but in raw OpenCL performance it is thoroughly outclassed. The Pro 575's 256-bit memory bus and 217.0 GB/s bandwidth are competitive for its era, but the RX 7650 GRE's 288.0 GB/s bandwidth with faster GDDR6 memory is strictly superior in throughput. For anyone building or upgrading a desktop system, the RX 7650 GRE is the only rational choice based on this data.

Architecture Differences

The architectural gap between these two AMD GPUs is generational and profound. The RX 7650 GRE uses the Navi 33 chip based on RDNA 3.0 architecture, built on a 6 nm TSMC process with 13,300 million transistors on a 204 mm² die. The Pro 575 uses the Ellesmere chip based on the much older GCN 4.0 architecture, built on a 14 nm GlobalFoundries process with 5,700 million transistors on a larger 232 mm² die. This means the RX 7650 GRE packs over twice the transistor count into a smaller area, achieving a transistor density of 65.2M per mm² versus the Pro 575's 24.6M per mm².

The RX 7650 GRE features 32 dedicated ray tracing cores, which the Pro 575 completely lacks. It also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro 575 is limited to DirectX 12 (12_0) and Vulkan 1.3. Both cards support OpenGL 4.6. The RX 7650 GRE's RDNA 3.0 architecture is designed for modern gaming and compute workloads with hardware ray tracing, while the Pro 575's GCN 4.0 architecture predates this capability entirely.

Memory architecture differs significantly as well. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus with a memory clock of 2250 MHz (18 Gbps effective), while the Pro 575 uses 4 GB of GDDR5 on a 256-bit bus with a memory clock of 1695 MHz (6.8 Gbps effective). The newer card's faster memory compensates for its narrower bus, resulting in higher overall bandwidth. The RX 7650 GRE also has a much higher boost clock at 2695 MHz and a game clock of 2350 MHz, whereas the Pro 575's clocks are not listed, but its texture rate of 140.3 GTexel/s versus the RX 7650 GRE's 345.0 GTexel/s indicates a massive clock and efficiency advantage for the newer part.

Specification Differences

The two cards differ in nearly every measurable specification. The RX 7650 GRE has 8 GB of GDDR6 memory versus the Pro 575's 4 GB of GDDR5. Memory bus width differs: 128-bit for the RX 7650 GRE versus 256-bit for the Pro 575. Bandwidth favors the newer card at 288.0 GB/s versus 217.0 GB/s.

Both cards have 2,048 shading units and 128 TMUs, but the ROP count differs: 64 ROPs on the RX 7650 GRE versus 32 ROPs on the Pro 575. This directly explains the pixel rate difference of 172.5 GPixel/s versus 35.07 GPixel/s. FP32 performance is 22.08 TFLOPS versus 4.489 TFLOPS, and FP16 performance follows the same 1:1 ratio for both cards.

Power requirements differ substantially: the RX 7650 GRE has a TDP of 170 W with a single 8-pin power connector and a suggested PSU of 450 W, while the Pro 575 has a TDP of 150 W with no power connectors listed and no suggested PSU. The RX 7650 GRE is a dual-slot card at 204 mm in length and 115 mm in height, while the Pro 575 uses an MXM Module form factor with no dimensions listed.

Interface standards also differ: the RX 7650 GRE uses PCIe 4.0 x8, while the Pro 575 uses PCIe 3.0 x16. Display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1 for the RX 7650 GRE, versus "Portable Device Dependent" for the Pro 575. The RX 7650 GRE has a release date of 2025-02-06 and a launch MSRP of 279 USD, while the Pro 575 was released on 2017-06-04 with no MSRP listed. The RX 7650 GRE is in the Radeon RX 7000 series with a predecessor of Navi II, while the Pro 575 is in the Radeon Pro Mac (500 Series) generation with no predecessor or successor listed.
