AMD Radeon RX 5600 OEM vs AMD Radeon RX 7900M Comparison

Head-to-Head Benchmarks

The benchmark database records two shared tests between the AMD Radeon RX 7900M and the AMD Radeon RX 5600 OEM: Geekbench OpenCL and Geekbench Vulkan. In both, the RX 7900M is the clear winner, and the margins are substantial.

In Geekbench OpenCL, the RX 7900M scores 129499, while the RX 5600 OEM scores 62427. This gives the RX 7900M a 107.4% advantage, meaning it more than doubles the compute performance of the older card in this API. In Geekbench Vulkan, the gap widens even further: the RX 7900M scores 158760 versus 53743 for the RX 5600 OEM, a 195.4% delta. That is nearly three times the raw Vulkan performance.

The wins are not split: the RX 7900M wins both head-to-head tests, and the RX 5600 OEM wins none. The average benchmark score reflects this dominance. The RX 7900M averages 97487 across all recorded benchmarks, placing it in the 94th percentile of all GPUs in the database. The RX 5600 OEM averages 58085, which is in the 87th percentile. While both are above-average performers, the 7900M sits far higher in the distribution.

Looking at nearest rivals helps contextualize the 7900M’s standing. Its average score is 0.4% above the AMD Radeon Pro VII (which scores 97131), 4.3% below the NVIDIA Quadro RTX 6000 (101872), 5.4% above the AMD Radeon Instinct MI60 (92466), and 6.3% above the NVIDIA RTX A4500 (91671). These are professional and workstation-class GPUs, and the 7900M slots comfortably among them.

Architecture Differences

The two cards come from different Radeon generations and use different underlying silicon. The AMD Radeon RX 7900M is built on the Navi 31 chip with the RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Navi Mobile (RX 7000M) generation. The AMD Radeon RX 5600 OEM uses the Navi 10 chip with the older RDNA 1.0 architecture, from the Navi (RX 5000) generation.

The manufacturing process differs significantly. The RX 7900M is fabricated on a 5 nm process at TSMC, while the RX 5600 OEM uses a 7 nm process, also at TSMC. This process advantage is reflected in transistor density: the 7900M packs 57,700 million transistors into a 529 mm² die, yielding a density of 109.1M transistors per mm². The 5600 OEM has 10,300 million transistors on a 251 mm² die, for a density of 41.0M per mm². The 7900M is more than twice as dense per square millimeter.

The compute resources are vastly different. The RX 7900M has 4608 shading units, 288 texture mapping units (TMUs), and 192 render output units (ROPs). It also features 72 ray tracing cores. The RX 5600 OEM has 2048 shading units, 128 TMUs, and 64 ROPs, with no ray tracing cores listed. This means the 7900M supports hardware ray tracing, while the 5600 OEM does not.

API support also differs. The RX 7900M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 5600 OEM supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The 12_2 feature level on the 7900M is a higher tier of DirectX 12 support.

The memory subsystem is built differently. The RX 7900M uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The RX 5600 OEM has 6 GB of GDDR6 on a 192-bit bus, with 288.0 GB/s, exactly half the bandwidth.

Specification Differences

The clock speeds are a key differentiator. The RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz. The RX 5600 OEM has a base clock of 1130 MHz, a boost clock of 1560 MHz, and a game clock of 1375 MHz. The memory clocks also differ: the 7900M runs at 2250 MHz (18 Gbps effective), while the 5600 OEM runs at 1500 MHz (12 Gbps effective).

The pixel and texture rates scale accordingly. The RX 7900M produces 401.3 GPixel/s and 601.9 GTexel/s. The RX 5600 OEM produces 99.84 GPixel/s and 199.7 GTexel/s. The floating-point performance (FP32) is 38.52 TFLOPS for the 7900M versus 6.390 TFLOPS for the 5600 OEM. FP16 performance is 77.05 TFLOPS (2:1) versus 12.78 TFLOPS (2:1).

Power and physical characteristics differ. The RX 7900M has a TDP of 180 W and is listed as an IGP (integrated graphics processor) with no power connectors and portable-device-dependent display outputs. The RX 5600 OEM has a TDP of 125 W, is a dual-slot card, requires a single 8-pin power connector, and has a suggested PSU of 300 W. Its display outputs are 1x HDMI 2.0b and 3x DisplayPort 1.4a. Both use PCIe 4.0 x16.

Production status and release dates are not the same. The RX 7900M is listed as Active, released on 2023-10-18, with a predecessor of Polaris Mobile and no successor. The RX 5600 OEM is End-of-life, released on 2020-01-20, with a predecessor of Vega and a successor of Navi II.

The Verdict

The data is unambiguous. The AMD Radeon RX 7900M outperforms the AMD Radeon RX 5600 OEM in every recorded shared benchmark, with deltas of 107.4% in OpenCL and 195.4% in Vulkan. The 7900M’s average benchmark score of 97487 is nearly 68% higher than the 5600 OEM’s 58085. The 7900M also sits in the 94th percentile versus the 87th for the 5600 OEM.

The RX 7900M is the newer, denser, more feature-rich part. It has more than double the shading units, more than double the TMUs, three times the ROPs, hardware ray tracing, a 5 nm process, and a 256-bit memory bus with twice the bandwidth. It is also a mobile IGP design, meaning it is intended for portable devices, while the 5600 OEM is a dual-slot desktop card.

For users who prioritize raw compute performance, modern API support, and ray tracing capability, the RX 7900M is the only choice from this data. The RX 5600 OEM, while still a solid performer relative to its immediate rivals (all within 0.8% of its average score), is simply in a lower performance class. The verdict is clear: the RX 7900M wins on every measurable axis in the database.

Where Each One Wins

AMD Radeon RX 7900M:

• Wins both head-to-head benchmarks: Geekbench OpenCL (129499 vs 62427) and Geekbench Vulkan (158760 vs 53743).
• Higher average benchmark score: 97487 versus 58085.
• 94th percentile ranking versus 87th for the 5600 OEM.
• Better suited for compute-heavy workloads given its 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 performance.
• Supports DirectX 12 Ultimate (12_2), enabling the latest feature set including ray tracing.
• Larger memory pool: 16 GB versus 6 GB, and double the memory bandwidth (576.0 GB/s vs 288.0 GB/s).
• More shading units (4608 vs 2048), TMUs (288 vs 128), and ROPs (192 vs 64).
• 72 ray tracing cores for hardware-accelerated ray tracing.

AMD Radeon RX 5600 OEM:

• Has no benchmark wins in the shared tests; the recorded data shows 0 wins.
• Still sits in the 87th percentile, which is above average for all GPUs.
• Its nearest rivals are extremely close (within 0.8%), indicating it is a consistent mid-tier performer relative to its peer group.
• Lower TDP (125 W versus 180 W) may be relevant for systems with modest power budgets, though it requires an 8-pin connector and a 300 W PSU.
• Dual-slot desktop form factor with fixed display outputs (1x HDMI 2.0b, 3x DisplayPort 1.4a), which is a conventional setup for desktop builds.
• Suitable for scenarios where the workload does not demand the 7900M’s extreme compute headroom, such as older DirectX 12 (12_1) applications.

The use-case split is simple: the RX 7900M is for high-end mobile devices where maximum performance, ray tracing, and future-proofing matter. The RX 5600 OEM is a legacy desktop part that remains competitive only within its own narrow performance band, and it cannot match the 7900M in any shared test.
