AMD Radeon Pro 5600M vs AMD Radeon RX 7900 XTX Comparison

The Verdict

The database comparison between the AMD Radeon RX 7900 XTX and the AMD Radeon Pro 5600M is decisively one-sided. The RX 7900 XTX wins all nine head-to-head benchmarks recorded, with no wins for the Pro 5600M. The average benchmark score for the RX 7900 XTX is 19,410, placing it in the 64th percentile of all GPUs, while the Pro 5600M averages 16,351, sitting in the 59th percentile. The RX 7900 XTX is the clear choice for any workload requiring maximum graphics throughput, particularly in desktop gaming and compute tasks. The Pro 5600M, with its 50 W power envelope and integrated form factor, is a legacy mobile solution; its recorded data shows it is only suitable for lightweight or legacy applications. The RX 7900 XTX holds a 5.6% lead in OpenCL, an 84.4% lead in Vulkan, and a 338.8% lead in GPU compute, making it the definitive pick for performance-focused users. The Pro 5600M should only be considered where its integrated, low-power design is an absolute requirement, as benchmark results show it trails by hundreds of percentage points in most tests.

Where Each One Wins

The RX 7900 XTX wins across every recorded benchmark category. In DirectX 10, it scores 166 versus 62, a 167.7% advantage. DirectX 11 shows an even larger gap: 356 versus 59, a 503.4% delta. DirectX 12 results are 131 versus 39, a 235.9% lead, and DirectX 9 shows 330 versus 118, a 179.7% advantage. The 2D graphics test (Passmark G2D) shows 1267 versus 679, an 86.6% lead, while the 3D graphics test (Passmark G3D) shows 31,238 versus 9,279, a 236.7% delta. The compute-oriented tests are where the RX 7900 XTX stretches its lead furthest: GPU compute scores 17,689 versus 4,031, a 338.8% advantage. In Geekbench, the RX 7900 XTX leads OpenCL with 50,465 versus 47,783 (5.6% delta) and Vulkan with 85,612 versus 46,425 (84.4% delta). The Pro 5600M has no winning categories in the head-to-head data. Its only comparable result is in Geekbench OpenCL, where it comes within 5.6% of the RX 7900 XTX, but it still loses. For users prioritizing any form of graphics performance, from legacy DirectX 9 titles to modern compute workloads, the RX 7900 XTX is the only rational choice based on the data.

Architecture Differences

The architectural gap between these two GPUs is substantial. The RX 7900 XTX is built on the Navi 31 chip using RDNA 3.0 architecture, codenamed Plum Bonito, and fabricated on a 5 nm process at TSMC. It contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The Pro 5600M uses the Navi 12 chip with RDNA 1.0 architecture, on a 7 nm process also at TSMC; its transistor count and die size are not recorded in the database. The RX 7900 XTX features 6,144 shading units, 384 texture mapping units, 192 ROPs, and 96 ray tracing cores. The Pro 5600M has 2,560 shading units, 160 TMUs, and 64 ROPs, with no ray tracing cores listed. Clock speeds differ dramatically: the RX 7900 XTX has a base clock of 1,929 MHz, a boost clock of 2,498 MHz, and a game clock of 2,365 MHz, while the Pro 5600M operates at a base of 822 MHz and a boost of 1,144 MHz. Memory configurations are also fundamentally different. The RX 7900 XTX uses 24 GB of GDDR6 on a 384-bit bus, delivering 960.0 GB/s of bandwidth at an effective 20 Gbps. The Pro 5600M uses 8 GB of HBM2 on a 2048-bit bus, delivering 394.2 GB/s at 1540 Mbps effective. The RX 7900 XTX has a pixel rate of 479.6 GPixel/s and a texture rate of 959.2 GTexel/s, versus 73.22 GPixel/s and 183.0 GTexel/s for the Pro 5600M. Floating-point performance shows a 10x gap: 61.39 TFLOPS FP32 and 122.8 TFLOPS FP16 (2:1) for the RX 7900 XTX, compared to 5.857 TFLOPS FP32 and 11.71 TFLOPS FP16 (2:1) for the Pro 5600M. Power and form factor differ as well: the RX 7900 XTX is a dual-slot card with a 355 W TDP, requiring two 8-pin connectors and a 750 W suggested PSU, measuring 287 mm long, 110 mm tall, and 51 mm wide. The Pro 5600M is an integrated graphics processor (IGP) with a 50 W TDP, no power connectors, and dimensions that are not recorded, as it is portable-device dependent. API support also differs: the RX 7900 XTX supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro 5600M supports DirectX 12 (12_1) and Vulkan 1.3; both support OpenGL 4.6. The RX 7900 XTX has a PCIe 4.0 x16 interface and offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C outputs, whereas the Pro 5600M also uses PCIe 4.0 x16 but its display outputs are portable-device dependent.

Head-to-Head Benchmarks

The most decisive victory for the RX 7900 XTX comes in Passmark GPU Compute, where it scores 17,689 against the Pro 5600M's 4,031. This 338.8% delta indicates a massive gap in general-purpose compute throughput, driven by the RX 7900 XTX's 61.39 TFLOPS FP32 performance versus 5.857 TFLOPS for the Pro 5600M. Next is DirectX 11, where the RX 7900 XTX scores 356 versus 59, a 503.4% lead; this is the largest percentage delta in the entire comparison, showing that legacy DirectX 11 workloads are overwhelmingly faster on the newer architecture. DirectX 12 follows with 131 versus 39, a 235.9% delta, and Passmark G3D shows 31,238 versus 9,279, a 236.7% lead, confirming that modern 3D rendering is also dominated by the RX 7900 XTX. The DirectX 9 test shows 330 versus 118, a 179.7% advantage, and DirectX 10 shows 166 versus 62, a 167.7% lead; these older APIs still favor the RX 7900 XTX by a wide margin.

The Geekbench Vulkan test is particularly revealing: 85,612 versus 46,425, an 84.4% delta. This is the closest of the modern API tests but still a decisive win, reflecting the RX 7900 XTX's superior shading unit count (6,144 versus 2,560) and higher clock speeds. The 2D graphics test (Passmark G2D) shows 1,267 versus 679, an 86.6% lead, which is the smallest percentage delta in the comparison, but it still favors the RX 7900 XTX. The OpenCL test in Geekbench is the closest overall: 50,465 versus 47,783, a 5.6% delta. This narrow margin is notable because the Pro 5600M's HBM2 memory with a 2048-bit bus provides substantial bandwidth per byte, though the RX 7900 XTX still wins due to its higher raw compute throughput and 960.0 GB/s of bandwidth. The overall pattern is clear: the RX 7900 XTX wins every test, with deltas ranging from 5.6% in OpenCL to 503.4% in DirectX 11. The Pro 5600M's best relative performance is in OpenCL, where its compute architecture is less disadvantaged, but even there it cannot overcome the RX 7900 XTX's advantages in shading units, clock speed, and memory bandwidth. The recorded data shows no scenario where the Pro 5600M outperforms the RX 7900 XTX, making the latter the unequivocal choice for any benchmark-driven decision.
