AMD Radeon Pro WX 7100 vs AMD Radeon RX 7650 GRE Comparison

FAQ

Q: How does the AMD Radeon RX 7650 GRE compare to the AMD Radeon Pro WX 7100 in raw compute performance?

A: The RX 7650 GRE delivers 22.08 TFLOPS of FP32 compute, while the Pro WX 7100 delivers 5.728 TFLOPS. This makes the RX 7650 GRE roughly 3.85x faster in theoretical FP32 throughput, a gap that is consistent with its 107% higher Geekbench OpenCL score (83109 vs 40148).

Q: Which card has higher memory bandwidth, and how do their memory subsystems differ?

A: The RX 7650 GRE has 288.0 GB/s of bandwidth from 8 GB of GDDR6 on a 128-bit bus, whereas the Pro WX 7100 has 224.0 GB/s from 8 GB of GDDR5 on a 256-bit bus. The newer card wins despite a narrower bus because GDDR6 runs at 18 Gbps effective versus 7 Gbps effective for GDDR5.

Q: What is the transistor density difference between the two architectures?

A: The RX 7650 GRE packs 13,300 million transistors into 204 mm² on a 6 nm TSMC process, yielding 65.2M transistors per mm². The Pro WX 7100 uses 5,700 million transistors across 232 mm² on a 14 nm GlobalFoundries process, giving only 24.6M per mm². The RX 7650 GRE is over 2.6x denser.

Q: Do both cards support ray tracing?

A: No. The RX 7650 GRE includes 32 dedicated RT cores as part of RDNA 3.0, while the Pro WX 7100 based on GCN 4.0 has no RT cores listed. The RX 7650 GRE also supports DirectX 12 Ultimate (12_2), whereas the Pro WX 7100 is limited to DirectX 12 (12_0).

Q: How do their production and release statuses differ?

A: The RX 7650 GRE is an Active product released on 2025-02-06, while the Pro WX 7100 is End-of-life and was released on 2016-11-09. The RX 7650 GRE's launch MSRP is 279 USD, and the Pro WX 7100's launch MSRP is 799 USD.

Q: Which card has a higher percentile ranking among all GPUs?

A: The RX 7650 GRE sits at the 83rd percentile with an average benchmark score of 42723, while the Pro WX 7100 sits at the 82nd percentile with an average score of 40063. The RX 7650 GRE edges out the older card by just one percentile point despite a much higher raw score.

The Verdict

The data is unambiguous: the AMD Radeon RX 7650 GRE is the superior performer in every measured category. Its 107% lead in Geekbench OpenCL (83109 vs 40148) is the only direct head-to-head benchmark available, and it wins that decisively. The RX 7650 GRE also leads in FP32 throughput (22.08 vs 5.728 TFLOPS), pixel rate (172.5 vs 39.78 GPixel/s), texture rate (345.0 vs 179.0 GTexel/s), and memory bandwidth (288.0 vs 224.0 GB/s).

The Pro WX 7100 retains one notable advantage: its 256-bit memory bus versus the RX 7650 GRE's 128-bit bus, and it consumes less power (130 W vs 170 W). But that lower power draw comes with far less compute capability per watt — the RX 7650 GRE delivers nearly 4x the FP32 performance for only 40 W more.

For any user choosing between these two, the RX 7650 GRE is the clear pick unless the single-slot form factor and 4x DisplayPort 1.4a output of the Pro WX 7100 are hard requirements. The RX 7650 GRE is dual-slot with 1x HDMI 2.1a and 3x DisplayPort 2.1. The RX 7650 GRE also has a launch MSRP of 279 USD versus 799 USD for the Pro WX 7100, but even ignoring that, the performance gap is overwhelming.

Head-to-Head Benchmarks

The single direct comparison in the data is Geekbench OpenCL, where the RX 7650 GRE scores 83109 against the Pro WX 7100's 40148. That is a 107% delta — the newer card more than doubles the older card's score. This aligns with the theoretical compute figures: 22.08 TFLOPS versus 5.728 TFLOPS FP32.

The RX 7650 GRE also wins on aggregate average benchmark score, posting 42723 versus 40063 for the Pro WX 7100 — a 6.6% lead. However, the Pro WX 7100 has additional benchmark results in the data (Geekbench Metal at 40357 and Geekbench Vulkan at 39683), which its rival lacks, so the average is calculated over different test sets.

Relative to their nearest rivals, the RX 7650 GRE sits within 1.3% of several NVIDIA cards — the RTX 4070 SUPER (-1.2%), Quadro M6000 24 GB (-1.2%), RTX 5050 Mobile (-1.3%), and Quadro M6000 (-1.3%). The Pro WX 7100 is within 1.3% of the Radeon Pro 580 (-0.6%), RTX 5070 (-0.8%), RTX A500 Mobile (+1.3%), and Radeon Pro 575 (+1.3%). This places both cards in a similar competitive tier relative to their contemporaries, but the RX 7650 GRE's absolute scores are far higher.

Specification Differences

The most striking difference is process node: 6 nm TSMC for the RX 7650 GRE versus 14 nm GlobalFoundries for the Pro WX 7100. Transistor count follows — 13,300 million versus 5,700 million — even though the RX 7650 GRE's die is smaller (204 mm² vs 232 mm²). Transistor density is 65.2M/mm² versus 24.6M/mm².

Clock speeds diverge sharply. The RX 7650 GRE boosts to 2695 MHz with a 2350 MHz game clock, while the Pro WX 7100 boosts to just 1243 MHz. Memory clocks are 2250 MHz (18 Gbps effective) versus 1750 MHz (7 Gbps effective). Memory type differs: GDDR6 on a 128-bit bus versus GDDR5 on a 256-bit bus, with bandwidth favoring the newer card at 288.0 GB/s versus 224.0 GB/s.

Shader resources are mixed: the Pro WX 7100 has more shading units (2304 vs 2048) and more TMUs (144 vs 128), but the RX 7650 GRE has double the ROPs (64 vs 32) and adds 32 RT cores that the older card lacks. Pixel rate is 172.5 GPixel/s versus 39.78 GPixel/s, and texture rate is 345.0 GTexel/s versus 179.0 GTexel/s.

Power and physical specs diverge: 170 W TDP with a 450 W suggested PSU and 1x 8-pin connector for the RX 7650 GRE, versus 130 W TDP with a 300 W suggested PSU and 1x 6-pin for the Pro WX 7100. The RX 7650 GRE is dual-slot, 204 mm long, 115 mm tall; the Pro WX 7100 is single-slot, 241 mm long, 112 mm tall. Bus interface is PCIe 4.0 x8 versus PCIe 3.0 x16. Display outputs are 1x HDMI 2.1a + 3x DisplayPort 2.1 versus 4x DisplayPort 1.4a.

Architecture Differences

The RX 7650 GRE uses RDNA 3.0 architecture on the Navi 33 chip, with the codename "Hotpink Bonefish" and belongs to the Navi III (RX 7000) generation. The Pro WX 7100 uses GCN 4.0 on the Ellesmere chip, part of the Radeon Pro Polaris (WX x100) generation.

RDNA 3.0 brings several features GCN 4.0 lacks. The RX 7650 GRE has 32 dedicated RT cores, enabling hardware ray tracing. It supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro WX 7100 is limited to DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

The RX 7650 GRE's FP16 performance is 22.08 TFLOPS at a 1:1 ratio with FP32, while the Pro WX 7100 also lists 5.728 TFLOPS FP16 at 1:1 — neither card has a specialized FP16 path. Neither card lists tensor cores.

Process technology is the biggest architectural enabler: 6 nm TSMC versus 14 nm GlobalFoundries. This allows the RX 7650 GRE to fit 13,300 million transistors in a smaller die, enabling higher clocks and more features per watt. The Pro WX 7100's 5,700 million transistors in a larger die reflect an older design philosophy with more shading units but far lower efficiency.

Where Each One Wins

The RX 7650 GRE wins in every benchmark and compute metric where data exists. Its 107% OpenCL lead, 3.85x FP32 advantage, and 4.3x pixel rate advantage make it the clear choice for compute-heavy workloads, modern gaming, or any task leveraging DirectX 12 Ultimate features. The 32 RT cores make it suitable for ray-traced content, which the Pro WX 7100 cannot handle.

The Pro WX 7100's wins are narrower and more situational. Its single-slot design and 4x DisplayPort 1.4a outputs make it a better fit for dense multi-GPU workstation builds where space is at a premium. Its lower 130 W TDP and 300 W suggested PSU mean it can drop into systems with smaller power supplies. Its 256-bit memory bus, while slower overall, may provide better latency characteristics for certain access patterns — though no benchmark data confirms this.

In terms of longevity, the RX 7650 GRE is Active production while the Pro WX 7100 is End-of-life. The RX 7650 GRE's PCIe 4.0 x8 interface, though narrower than PCIe 3.0 x16, offers higher bandwidth per lane. For software compatibility, the RX 7650 GRE's Vulkan 1.4 support is newer than the Pro WX 7100's Vulkan 1.3.

The verdict is straightforward: the RX 7650 GRE wins on raw performance, modern features, and efficiency per transistor. The Pro WX 7100 only remains relevant for legacy workstation deployments requiring its specific form factor or output configuration.
