Architecture Differences

The two cards are built on fundamentally different architectures that define their capabilities. The RX 7650 GRE uses the Navi 33 chip on TSMC's 6 nm process node, packing 13,300 million transistors into a 204 mm² die. This translates to a transistor density of 65.2M per mm². In contrast, the Pro 580X uses the Ellesmere chip built on GlobalFoundries' 14 nm process, with 5,700 million transistors on a larger 232 mm² die, resulting in a much lower density of 24.6M per mm².

The RDNA 3.0 architecture of the RX 7650 GRE brings modern features that the GCN 4.0 Pro 580X lacks. Most notably, the RX 7650 GRE includes 32 ray tracing cores, while the Pro 580X has none. This is a critical difference for any modern gaming or rendering workload that utilizes ray tracing. The RX 7650 GRE also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the Pro 580X is limited to DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

Clock speeds further illustrate the generational leap. The RX 7650 GRE has a base clock of 1720 MHz, a game clock of 2350 MHz, and a boost clock of 2695 MHz. The Pro 580X is significantly slower, with a base clock of 1100 MHz and a boost clock of just 1200 MHz. The memory systems also differ: the RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth, while the Pro 580X uses 8 GB of GDDR5 on a 256-bit bus with 218.9 GB/s bandwidth. The newer card achieves higher bandwidth despite a narrower bus thanks to faster memory clocks.

Where Each One Wins

The RX 7650 GRE is the clear winner in virtually every measurable performance category. In the only head-to-head benchmark available, Geekbench OpenCL, it wins decisively. Its FP32 compute throughput is 22.08 TFLOPS compared to the Pro 580X's 5.530 TFLOPS, a fourfold advantage. The pixel rate is also far superior at 172.5 GPixel/s versus 38.40 GPixel/s, and the texture rate is 345.0 GTexel/s versus 172.8 GTexel/s. For any compute-heavy or graphically intensive task, the RX 7650 GRE is the obvious choice.

The Pro 580X does have a few areas where it is not entirely outclassed. It has more shading units (2,304 vs 2,048) and more TMUs (144 vs 128), but these advantages are negated by the massive clock speed and architecture differences. Its 256-bit memory bus is wider than the RX 7650 GRE's 128-bit bus, but the lower bandwidth means this does not help in practice. The Pro 580X is also an IGP (integrated graphics processor) designed for Apple's MPX bus interface, which means it is intended for specific Mac Pro systems. The RX 7650 GRE is a standard dual-slot PCIe 4.0 x8 card.

Where the Pro 580X might "win" is in niche compatibility scenarios. Its Apple MPX interface and 2x HDMI 2.0b outputs are tailored for older Mac systems, whereas the RX 7650 GRE uses 1x HDMI 2.1a and 3x DisplayPort 2.1. If you own a compatible Mac Pro, the Pro 580X is the only one of the two that will physically fit and function. However, in raw performance, the RX 7650 GRE dominates every benchmark.

Specification Differences

The two cards differ in nearly every specification field. The process node is a major difference: the RX 7650 GRE uses 6 nm TSMC, while the Pro 580X uses 14 nm GlobalFoundries. Transistor count differs significantly (13,300 million vs 5,700 million), as does die size (204 mm² vs 232 mm²).

Clock speeds show the RX 7650 GRE with a 1720 MHz base and 2695 MHz boost, compared to the Pro 580X's 1100 MHz base and 1200 MHz boost. The memory configurations differ in type (GDDR6 vs GDDR5), bus width (128-bit vs 256-bit), and bandwidth (288.0 GB/s vs 218.9 GB/s), though both have 8 GB capacity.

Compute resources are split: the RX 7650 GRE has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores. The Pro 580X has 2,304 shading units, 144 TMUs, 32 ROPs, and no RT cores. The pixel rate is 172.5 GPixel/s for the RX 7650 GRE versus 38.40 GPixel/s for the Pro 580X, and the texture rate is 345.0 GTexel/s versus 172.8 GTexel/s. FP32 performance is 22.08 TFLOPS versus 5.530 TFLOPS.

Power and physical specifications also diverge. The RX 7650 GRE has a TDP of 170 W, requires a 450 W suggested PSU, uses a 1x 8-pin power connector, and is a dual-slot card measuring 204 mm in length. The Pro 580X has a higher TDP of 185 W but no listed power connector or PSU requirement, as it is an IGP. The bus interface differs: PCIe 4.0 x8 for the RX 7650 GRE versus Apple MPX for the Pro 580X. Display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1 for the new card, versus 2x HDMI 2.0b for the old one.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and it is a blowout. The RX 7650 GRE scores 83,109, while the Pro 580X scores 36,426. This is a delta of 128.2%, meaning the RX 7650 GRE is over twice as fast. This single result encapsulates the entire performance relationship between the two cards.

To put this in context, the RX 7650 GRE's average benchmark score is 42,723, and its nearest rivals include the NVIDIA GeForce RTX 4070 SUPER (43,223, delta -1.2%) and the NVIDIA Quadro M6000 24 GB (43,262, delta -1.2%). This places it in the 83rd percentile of all GPUs. The Pro 580X has an average score of 38,706, putting it in the 82nd percentile, with rivals like the NVIDIA GeForce MX570 A (38,691, delta 0%) and the AMD Radeon Pro 575X (39,116, delta -1%).

The interesting nuance is that despite the 128.2% difference in the head-to-head OpenCL test, their overall average scores are closer (42,723 vs 38,706). This is because the Pro 580X has additional benchmark results in Geekbench Metal (39,577) and Geekbench Vulkan (40,115), which are not available for the RX 7650 GRE. In those specific APIs, the Pro 580X performs better than it does in OpenCL, narrowing the overall gap in the percentile rankings.

The Verdict

The data is unambiguous: the AMD Radeon RX 7650 GRE is the superior graphics card in nearly every way. It offers 128.2% higher OpenCL performance, a more modern architecture with ray tracing support, faster memory, and higher clock speeds. For any gaming, rendering, or compute workload, the RX 7650 GRE is the card to choose. Its 83rd percentile ranking and proximity to cards like the RTX 4070 SUPER confirm it is a strong performer in the current market.

The AMD Radeon Pro 580X, however, is not without a purpose. Its 82nd percentile ranking is surprisingly close to the newer card, despite the massive gap in raw compute. This is largely due to its strong Metal and Vulkan scores, which are relevant for macOS applications. Its Apple MPX interface and 2x HDMI 2.0b outputs make it the only viable option for older Mac Pro systems that require this specific form factor. If you are upgrading a legacy Mac and cannot use a standard PCIe card, the Pro 580X is the only one of these two that will work.

For a typical PC builder, the choice is obvious: the RX 7650 GRE is faster, more efficient (170 W vs 185 W TDP), and supports modern APIs. It is an active product with a launch MSRP of 279 USD. The Pro 580X is end-of-life and limited to a niche Apple ecosystem. Unless you are locked into that ecosystem, the RX 7650 GRE is the only rational selection based on the benchmark data.
