AMD Radeon RX 5600M vs NVIDIA GeForce RTX 5080 Comparison

The Verdict

The NVIDIA GeForce RTX 5080 is the definitive choice for desktop and high-performance workloads. Benchmark results show it dominating every shared test, with an average benchmark score of 56,083 against the AMD Radeon RX 5600M's 46,601. In the three head-to-head tests, the RTX 5080 wins all three, with deltas ranging from 295.9% to 554.3%. The RX 5600M is an end-of-life mobile part, and the data reflects that: it trails by massive margins in every workload measured.

The RTX 5080 belongs in a desktop workstation or enthusiast gaming rig where its dual-slot cooler and 360 W TDP can be accommodated. The RX 5600M, as an integrated graphics product for portable devices, suits a laptop that needs modest 3D acceleration. Its 85th percentile ranking versus all GPUs is respectable, but its nearest rivals (Intel Arc A530M, AMD Radeon RX 6550M, NVIDIA RTX A2000) are all within 1.4% of its average score, indicating it is competitive only within its own low-power mobile class.

For anyone comparing these two directly, the RTX 5080 is faster in every benchmark category recorded. The RX 5600M's only advantage is its form factor: it is an IGP with no power connectors, making it suitable only for portable devices. The RTX 5080, by contrast, requires a 750 W power supply and a 16-pin connector. The data shows no scenario where the RX 5600M wins a performance comparison.

Architecture Differences

The two GPUs come from completely different eras and design philosophies. The RTX 5080 uses the GB203 chip on a 5 nm TSMC process, packing 45,600 million transistors into a 378 mm² die. The RX 5600M uses the Navi 10 chip on a 7 nm TSMC process, with 10,300 million transistors on a 251 mm² die. The transistor density difference is stark: 120.6M per mm² for the RTX 5080 versus 41.0M per mm² for the RX 5600M.

The RTX 5080 is built on Blackwell 2.0 architecture, while the RX 5600M uses RDNA 1.0. The RTX 5080 has 10,752 shading units, 336 TMUs, and 112 ROPs, alongside 84 RT cores and 336 tensor cores. The RX 5600M has 2,304 shading units, 144 TMUs, and 64 ROPs, with no RT cores and no tensor cores. This means the RTX 5080 supports hardware ray tracing and AI acceleration, while the RX 5600M does not.

Memory configurations are also divergent. The RTX 5080 has 16 GB of GDDR7 on a 256-bit bus, delivering 960.0 GB/s of bandwidth. The RX 5600M has 6 GB of GDDR6 on a 192-bit bus, providing 288.0 GB/s. Clock speeds differ as well: the RTX 5080 boosts to 2617 MHz, while the RX 5600M boosts to 1265 MHz. The RTX 5080 also supports PCIe 5.0 x16, versus PCIe 4.0 x16 for the RX 5600M.

Feature support shows generational separation. The RTX 5080 lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 5600M lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 also has dedicated display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b), while the RX 5600M's outputs are listed as "Portable Device Dependent."

Where Each One Wins

The RTX 5080 wins every single benchmark where both GPUs were measured. In 3DMark Steel Nomad DX12, it scores 8,637 versus 1,320, a 554.3% advantage. In Geekbench OpenCL, it scores 235,901 versus 59,589, a 295.9% lead. In Geekbench Vulkan, it scores 255,450 versus 48,843, a 423% margin. There is no workload category where the RX 5600M outperforms the RTX 5080.

The RTX 5080 also has additional benchmark results that the RX 5600M lacks entirely. These include PassMark DirectX 10 (208), DirectX 11 (324), DirectX 12 (151), DirectX 9 (389), G2D (1,415), G3D (36,565), and GPU Compute (21,789). The RX 5600M has a Geekbench Metal score of 76,653, which the RTX 5080 does not have recorded, but this reflects platform-specific testing rather than a performance advantage.

Where the RX 5600M "wins" is in deployment flexibility. It is an IGP with no power connectors, meaning it can fit in thin laptops without discrete power delivery. Its 150 W TDP is lower than the RTX 5080's 360 W, though the RTX 5080 is a desktop card. The RX 5600M is end-of-life, while the RTX 5080 remains active in production. For a portable device needing basic GPU capability, the RX 5600M is the only practical option of the two.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test shows the largest relative gap. The RTX 5080 scores 8,637, while the RX 5600M scores 1,320. This 554.3% delta is the biggest margin in any shared test, reflecting the RTX 5080's far stronger geometry throughput and modern API optimization. The RX 5600M's RDNA 1.0 architecture struggles with the DX12 workload that Blackwell 2.0 handles with ease.

In Geekbench Vulkan, the RTX 5080 scores 255,450 versus 48,843 for the RX 5600M, a 423% advantage. Vulkan is a cross-platform API, and the results show the RTX 5080's superior driver efficiency and hardware capability. The RX 5600M's lack of dedicated RT and tensor cores likely contributes to its lower score, though the gap is so large that core architecture alone cannot explain it.

Geekbench OpenCL shows a 295.9% lead for the RTX 5080, with scores of 235,901 and 59,589 respectively. OpenCL is a compute-oriented workload, and the RTX 5080's 45,600 million transistors versus 10,300 million gives it a massive resource advantage. The RX 5600M's FP16 performance of 11.66 TFLOPS (2:1 rate) is higher than its FP32, but OpenCL likely stresses FP32, where the RTX 5080's 56.28 TFLOPS dominates.

The RTX 5080's additional PassMark results reinforce its position. Its G3D score of 36,565 and GPU Compute score of 21,789 are not directly comparable to the RX 5600M since the RX 5600M lacks these tests, but they show consistent strength across legacy and modern DirectX versions. The RX 5600M's sole unique result, Geekbench Metal at 76,653, indicates its Apple-platform compatibility, but the RTX 5080 was not tested in Metal, so no cross-comparison exists.

The nearest rival data places each GPU in context. The RTX 5080 sits only 0.6% above the AMD Radeon 8060S and 0.7% above the RX 6750 GRE 12 GB, showing it is closely matched within its own performance tier. The RX 5600M is essentially tied with the Intel Arc A530M at 0% delta, and slightly ahead of the RX 6550M by 0.2%. This confirms the RX 5600M's position at the lower end of the mobile GPU market, while the RTX 5080 competes near the top of the desktop range.

In summary, the RTX 5080 is a generational leap over the RX 5600M in every measurable way. The RX 5600M remains a viable option only for portable devices where its IGP form factor is a requirement, not a choice. For any workload where performance matters, the RTX 5080 is the clear winner by every metric in the database.
