AMD Radeon 680M vs AMD Radeon PRO W7500 Comparison

The AMD Radeon PRO W7500 and the AMD Radeon 680M represent two fundamentally different approaches to graphics processing, yet both are built by AMD and share a 6 nm manufacturing process. The PRO W7500 is a discrete, single-slot workstation card, while the 680M is an integrated graphics processor (IGP) designed for portable devices. The benchmark data reveals a decisive performance gap, but the architectural and contextual differences are equally important for understanding where each part fits.

Head-to-Head Benchmarks

The most direct comparison available comes from two synthetic workload tests: Geekbench OpenCL and Geekbench Vulkan. In both cases, the AMD Radeon PRO W7500 delivers a dominant victory. In the OpenCL test, the PRO W7500 scores 58,213 points, while the Radeon 680M manages only 23,468 points. This translates to a 148.1% advantage for the discrete card. The gap widens further in the Vulkan test, where the PRO W7500 achieves 68,634 points against the 680M’s 21,965 points, a 212.5% lead. These are not marginal differences; the PRO W7500 is operating in a completely different performance tier.

Looking at the broader benchmark context, the average benchmark score for the PRO W7500 is 16,415, placing it in the 59th percentile of all GPUs. Its nearest rivals include the NVIDIA RTX PRO 6000 Blackwell (16,408, 0% delta) and the AMD Radeon RX 5700 XT (16,361, 0.3% delta), showing it sits just above those parts. Conversely, the Radeon 680M has an average score of 15,270, which lands it in the 57th percentile. Its closest competitors are the NVIDIA GeForce GTX 580 (15,283, -0.1% delta) and the NVIDIA GeForce RTX 2060 (15,290, -0.1% delta). While the 680M is only about 7% behind the PRO W7500 in average score, this aggregate figure masks the massive divergence seen in the compute-oriented Geekbench tests, where the PRO W7500 is 2.5 to 3 times faster.

The data shows that the PRO W7500’s wins are not just quantitative but qualitative. In OpenCL, a common compute API, its score of 58,213 is nearly 2.5 times the 680M's 23,468. In Vulkan, a modern graphics and compute API, the PRO W7500’s 68,634 score is more than three times the 680M’s 21,965. This suggests that the PRO W7500 is not merely faster at rendering frames, but is substantially more capable at general-purpose GPU workloads, which is a critical factor for professional applications.

Architecture Differences

The two GPUs are built on different generations of AMD’s RDNA architecture. The Radeon PRO W7500 uses RDNA 3.0, with the chip codenamed "Hotpink Bonefish" (Navi 33), while the Radeon 680M uses the older RDNA 2.0 architecture, with the chip codenamed "Rembrandt+" (Navi II IGP). This generational leap is a primary driver of the performance disparity. The PRO W7500 is part of the "Radeon Pro Navi (Navi III Series)" generation, whereas the 680M belongs to the "Navi II IGP (Rembrandt Mobile)" generation.

The die sizes and transistor counts are surprisingly similar, but the configuration differs dramatically. The PRO W7500 has a die size of 204 mm² and houses 13,300 million transistors, resulting in a density of 65.2M / mm². The 680M has a slightly larger die at 208 mm² but slightly fewer transistors at 13,100 million, giving a density of 63.0M / mm². Both are fabricated on a 6 nm process at TSMC. The key difference lies in how those transistors are used. The PRO W7500 allocates resources to a massive array of compute units, while the 680M, as an IGP, shares the die with other components and is more constrained.

The compute resource gap is stark. The PRO W7500 features 1,792 shading units, 112 texture mapping units (TMUs), and 64 render output units (ROPs). In contrast, the 680M has only 768 shading units, 48 TMUs, and 32 ROPs. This means the PRO W7500 has more than double the shading units and TMUs, and exactly double the ROPs. The ray tracing hardware follows a similar pattern, with the PRO W7500 containing 28 ray tracing cores compared to the 680M’s 12. This explains the PRO W7500’s higher theoretical pixel rate of 108.8 GPixel/s and texture rate of 190.4 GTexel/s, versus the 680M's 70.40 GPixel/s and 105.6 GTexel/s.

Memory is another fundamental differentiator. The PRO W7500 is a discrete card with 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering a bandwidth of 256.0 GB/s. The 680M, being an IGP, has no dedicated memory; it uses "System Shared" memory, with its bandwidth described as "System Dependent." This means the 680M’s performance is heavily influenced by the system's RAM and memory controller, whereas the PRO W7500 has predictable, dedicated bandwidth.

The Verdict

The data presents a clear picture: the AMD Radeon PRO W7500 is the superior performer in every measured category. Its 148.1% lead in OpenCL and 212.5% lead in Vulkan over the Radeon 680M demonstrate that it is not just a faster version of the same product, but a completely different class of hardware. The PRO W7500 is designed for professional workloads where compute throughput and dedicated memory are paramount. Its 59th percentile ranking and proximity to parts like the NVIDIA RTX PRO 6000 Blackwell (0% delta) and the AMD Radeon RX 5700 XT (0.3% delta) confirm its position in the discrete GPU market.

The Radeon 680M, on the other hand, is an integrated solution for portables. While its average benchmark score of 15,270 places it near the NVIDIA GeForce RTX 2060 (-0.1% delta) in aggregate, its performance in compute-heavy tests is far lower. The 680M’s strength is its integration, not its raw power. For a user needing a dedicated workstation GPU for rendering, simulation, or AI tasks, the PRO W7500 is the only choice based on this data. For a portable device where power efficiency and integration are key, the 680M serves a purpose, but it cannot match the discrete card's capability. The choice is not between two equal options; it is between a professional tool and a mobile convenience.

Where Each One Wins

The AMD Radeon PRO W7500 wins decisively in all benchmark categories that were tested. Its wins in OpenCL and Vulkan are absolute, with deltas of 148.1% and 212.5% respectively. This indicates a clear win for professional compute, 3D rendering, and any workload that leverages the GPU’s full compute pipeline. The PRO W7500 also wins on specifications that support these tasks: it has 8 GB of dedicated GDDR6 memory, a 256.0 GB/s memory bandwidth, and a 59th percentile ranking among all GPUs. Its nearest rivals in average score are the NVIDIA RTX PRO 6000 Blackwell (0% delta) and the AMD Radeon RX 5700 XT (0.3% delta), showing it is competitive with high-end discrete parts.

The AMD Radeon 680M’s wins are more contextual. It has no benchmark wins in the head-to-head tests, but it wins on integration and efficiency. As an IGP, it requires no separate power connectors and has a TDP of 50 W, compared to the PRO W7500’s 70 W. Its memory is "System Shared," which means it doesn't require a dedicated memory purchase. For a portable device, this is a significant advantage. Its average score of 15,270 and 57th percentile ranking show it is not a slouch for integrated graphics, sitting near the NVIDIA GeForce RTX 2060 (-0.1% delta) in aggregate performance. However, this aggregate performance is heavily weighted by its dedicated memory advantage in a desktop context; in an IGP context, its performance is limited by system memory. The 680M wins in scenarios where space, power, and cost of integration are the primary constraints, not absolute performance.
