AMD Radeon RX 5600M vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive advantage for the NVIDIA GeForce RTX 4080 Mobile in the two directly comparable benchmark tests. In Geekbench OpenCL, the RTX 4080 Mobile scores 159,575 against the RX 5600M’s 59,589, a delta of 62.7% in favor of the NVIDIA part. The gap widens slightly in Geekbench Vulkan, where the RTX 4080 Mobile reaches 145,807 while the RX 5600M manages 48,843, a 66.5% difference. These are not marginal wins; they represent a fundamental performance tier separation.

The RX 5600M does hold a curious advantage in aggregate scoring. Its average benchmark score across all recorded tests is 46,601, which places it in the 85th percentile of all GPUs in the database. The RTX 4080 Mobile, despite winning both head-to-head tests, has an average score of only 38,135 and sits in the 81st percentile. This inversion is explained by the benchmark mix: the RTX 4080 Mobile’s average is dragged down by PassMark tests where it records very low scores, such as 157 in DirectX 10 and 96 in DirectX 12. The RX 5600M’s benchmark list is shorter and does not include those low-scoring PassMark entries, so its average is less penalized.

Looking at the nearest rivals for context, the RX 5600M’s average of 46,601 is essentially tied with the Intel Arc A530M at 46,614 (a 0% delta) and the AMD Radeon RX 6550M at 46,702 (a 0.2% deficit). It also sits 1.2% above the NVIDIA RTX A2000 and 1.4% above the NVIDIA RTX 5880 Ada Generation. The RTX 4080 Mobile’s average of 38,135 is 0.4% below the NVIDIA GeForce MX570 and 0.6% below the NVIDIA GeForce RTX 5080 Mobile, while sitting 1.3% above both the NVIDIA GeForce RTX 4070 and the NVIDIA Tesla P4. These neighborhood comparisons suggest that each card occupies a distinct performance niche despite the direct benchmark mismatch.

Architecture Differences

The architectural gap between these two mobile GPUs is substantial. The AMD Radeon RX 5600M is built on the Navi 10 chip using RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. It packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0 million per square millimeter. The NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip with Ada Lovelace architecture, made on a 5 nm process, also at TSMC. It contains 35,800 million transistors across a 294 mm² die, for a density of 121.8 million per square millimeter. The 5 nm node allows NVIDIA to fit over three times as many transistors into a die that is only 17% larger.

The compute resources differ even more dramatically. The RTX 4080 Mobile has 7,424 shading units, 232 texture mapping units, and 80 raster output units. The RX 5600M has 2,304 shading units, 144 TMUs, and 64 ROPs. NVIDIA’s part also includes 58 ray tracing cores and 232 tensor cores, neither of which the RX 5600M has at all. In terms of raw throughput, the RTX 4080 Mobile delivers 24.72 TFLOPS of FP32 compute and the same 24.72 TFLOPS of FP16 compute (at a 1:1 ratio). The RX 5600M offers 5.829 TFLOPS of FP32 and 11.66 TFLOPS of FP16, but only at a 2:1 ratio, meaning its half-precision performance is achieved through math rate doubling rather than dedicated hardware.

Memory configurations also diverge. The RTX 4080 Mobile has 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s of bandwidth. The RX 5600M has 6 GB of GDDR6 on the same 192-bit bus, but only 288.0 GB/s of bandwidth. Clock speeds tell a similar story: the RTX 4080 Mobile boosts to 1665 MHz with a base of 1290 MHz, while the RX 5600M boosts to just 1265 MHz with a base of 1035 MHz. The effective memory speed is 18 Gbps on the NVIDIA part versus 12 Gbps on the AMD part.

The power envelope is notable. The RTX 4080 Mobile is rated at 110 W TDP, while the RX 5600M is rated at 150 W. This means the NVIDIA part delivers far higher performance while drawing less power, a direct consequence of the more advanced 5 nm process and newer architecture. Both are integrated GPUs (IGP slot width) with no power connectors and portable-device-dependent display outputs. Both use PCIe 4.0 x16 interfaces and support DirectX 12, OpenGL 4.6, and Vulkan 1.4, though NVIDIA’s DirectX support is at 12 Ultimate (12_2) versus AMD’s 12 (12_1).

Where Each One Wins

The data suggests the RTX 4080 Mobile wins decisively in compute-heavy workloads. Its OpenCL score of 159,575 is 2.7 times higher than the RX 5600M’s 59,589, indicating a massive advantage in general-purpose GPU compute tasks such as rendering, physics simulation, and machine learning inference. The Vulkan score of 145,807 versus 48,843 is even more lopsided at nearly 3 times, suggesting the NVIDIA architecture handles modern cross-platform graphics APIs with far greater efficiency.

The RX 5600M’s wins are more subtle and statistical than practical. Its 85th percentile ranking versus the RTX 4080 Mobile’s 81st percentile reflects the different benchmark distributions, not actual superiority in any measured workload. The RX 5600M’s average score of 46,601 exceeds the RTX 4080 Mobile’s 38,135, but this is an artifact of the RTX 4080 Mobile’s inclusion of low-scoring PassMark tests. The PassMark results for the RTX 4080 Mobile are oddly inconsistent: 24,926 in G3D and 11,191 in GPU Compute look respectable, but 157 in DirectX 10, 244 in DirectX 11, 96 in DirectX 12, and 286 in DirectX 9 are anomalously low. These likely reflect driver or test-environment issues rather than genuine hardware capability.

For gaming workloads, the RTX 4080 Mobile’s 24.72 TFLOPS of FP32 and 133.2 GPixel/s pixel rate versus the RX 5600M’s 5.829 TFLOPS and 80.96 GPixel/s point to a clear NVIDIA advantage in rasterized and ray-traced gaming. The presence of dedicated RT cores and tensor cores on the RTX 4080 Mobile makes it the only one of the two capable of hardware-accelerated ray tracing and DLSS-style upscaling. The RX 5600M has no such hardware.

The Verdict

For any user prioritizing raw performance in modern workloads, the NVIDIA GeForce RTX 4080 Mobile is the clear choice from the recorded data. It wins both head-to-head benchmarks by margins exceeding 60%, delivers over four times the FP32 throughput, offers double the memory capacity and 50% more bandwidth, and does all this at a lower TDP of 110 W versus 150 W. The newer 5 nm process, Ada Lovelace architecture, and dedicated ray tracing and tensor cores make it the more future-proof option.

The AMD Radeon RX 5600M, however, is not without a case. Its 85th percentile ranking and higher average benchmark score (46,601 versus 38,135) indicate that in the broader GPU landscape, it competes favorably with other mid-range mobile parts. Its nearest rivals are the Intel Arc A530M and AMD Radeon RX 6550M, with which it trades within 0.2%. For users whose workloads are dominated by the specific tests where the RX 5600M records strong results, such as Geekbench Metal (76,653) and Geekbench OpenCL (59,589), it may still be sufficient. Its 6 GB of GDDR6 memory is adequate for 1080p gaming at moderate settings, though the 12 GB on the RTX 4080 Mobile is better suited to higher resolutions and texture-heavy titles.

The production status is decisive for purchasing decisions: the RX 5600M is end-of-life, released in July 2020, while the RTX 4080 Mobile is active and was released in January 2023. The RX 5600M’s predecessor is Polaris Mobile, and it has no successor listed. The RTX 4080 Mobile’s predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile. The data indicates that the RTX 4080 Mobile is the superior product in nearly every measurable dimension, with the RX 5600M’s higher aggregate score being the only statistical counterpoint.
