NVIDIA GeForce RTX 4080 Mobile vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison challenge. The NVIDIA GeForce RTX 4080 Mobile has a rich set of nine benchmark scores across various DirectX and compute workloads, while the NVIDIA GeForce RTX 5080 SUPER has only a single score in the 3DMark Steel Nomad DX12 test. This asymmetry means a direct per-test head-to-head table is impossible; instead, the comparison must rely on aggregate scores and the limited shared context.

The RTX 4080 Mobile shows an average benchmark score of 38,135. Its closest rival in the database, the NVIDIA GeForce MX570, averages 38,299, a difference of only 0.4%, placing the 4080 Mobile essentially at parity with that entry-level part in aggregate terms. The RTX 5080 SUPER, by contrast, has an average score of 3,075, which is dramatically lower. However, this figure comes from a single, very demanding test: 3DMark Steel Nomad DX12. The 5080 SUPER's nearest rivals in the database are the NVIDIA Quadro P1000 at 3,163 (2.8% ahead), the Intel Arc Pro B60 at 3,182 (3.4% ahead), and the NVIDIA GeForce 820A at 2,983 (3.1% behind). This context suggests the 5080 SUPER's raw score, while low in absolute terms, is competitive within its own narrow benchmark set.

The RTX 4080 Mobile's best individual results include a Geekbench OpenCL score of 159,575 and a Geekbench Vulkan score of 145,807. Its Passmark G3D score is 24,926, with a G2D score of 929. In compute-heavy workloads, it delivers a Passmark GPU Compute score of 11,191. The 5080 SUPER has no comparable scores in these specific tests, so a direct comparison on those workloads cannot be drawn from the database. The only overlapping metric is the average score, where the 4080 Mobile leads by a factor of roughly 12.4 times. This is not a meaningful comparison, however, because the 5080 SUPER's average is based on a single next-generation DX12 test, whereas the 4080 Mobile's average includes older API tests like Passmark DirectX 9 (score 286) and DirectX 10 (score 157), which tend to produce lower raw numbers.

The percentile rankings reinforce the divergence. The RTX 4080 Mobile sits in the 81st percentile against all GPUs in the database, indicating it outperforms the vast majority of recorded parts. The RTX 5080 SUPER sits in the 19th percentile, but again, this is derived from one test that likely stresses the GPU in a way older tests do not. The data suggests the 5080 SUPER is a very different kind of product, not a direct successor in the same performance tier. The 4080 Mobile's nearest rivals include the RTX 5080 Mobile (average 38,349, delta -0.6%), showing that the mobile 5080 is nearly identical in aggregate performance to the 4080 Mobile, while the desktop 5080 SUPER trails far behind in the limited dataset.

Where Each One Wins

Based strictly on the recorded benchmarks, the RTX 4080 Mobile wins in every category where both have data, simply because the 5080 SUPER lacks scores for those tests. The 4080 Mobile shows strength in OpenCL and Vulkan compute workloads, with Geekbench scores of 159,575 and 145,807 respectively. It also demonstrates solid performance across legacy DirectX APIs, with Passmark scores of 244 for DirectX 11 and 96 for DirectX 12. The 5080 SUPER's sole win is in the 3DMark Steel Nomad DX12 test, where it scores 3,075. This test is a modern, demanding workload that likely represents future gaming requirements, but no comparable score exists for the 4080 Mobile in the database.

The use-case split is therefore stark. For users running legacy or compute-heavy applications that rely on OpenCL, Vulkan, or older DirectX versions, the 4080 Mobile is the only option with data, and its scores are robust. For users targeting the latest DX12 titles, the 5080 SUPER's single score provides a reference point, but without a matching 4080 Mobile score, no relative conclusion can be made. The 4080 Mobile also holds the advantage in aggregate performance, with an average score of 38,135 versus 3,075, but this is an artifact of the test count disparity.

The data implies that the 4080 Mobile is a versatile, well-tested part across many workloads, while the 5080 SUPER is a new or niche entry with minimal recorded performance data. The 5080 SUPER's percentile rank of 19th and its nearest rivals (Quadro P1000, Arc Pro B60, 820A) suggest that in the single test it ran, it performs at a level comparable to older or lower-tier GPUs. This is likely due to the extreme demands of the Steel Nomad test, not a reflection of real-world weakness. The 4080 Mobile, in contrast, has a percentile rank of 81st, indicating broad superiority across the database's full test suite.

The Verdict

The data presents a clear but conditional picture. The RTX 4080 Mobile is a well-characterized mobile GPU with extensive benchmark coverage, sitting in the 81st percentile of all GPUs. Its nine scores span Geekbench OpenCL (159,575), Geekbench Vulkan (145,807), and multiple Passmark tests, making it a versatile choice for a wide range of workloads in a portable form factor. Its 110 W TDP and integrated design (no power connectors, IGP slot width) confirm its mobile intent.

The RTX 5080 SUPER is a desktop-class part with a 415 W TDP, dual-slot cooler, and a 1x 16-pin power connector. Its single 3DMark Steel Nomad DX12 score of 3,075 places it in the 19th percentile, but this is likely a result of the test's extreme demands rather than a true indicator of weakness. Its nearest rivals in that specific test, such as the Quadro P1000 and Arc Pro B60, are not comparable in raw specifications, making the percentile ranking misleading for cross-generational assessment.

For users seeking a mobile GPU with proven performance across legacy and modern APIs, the RTX 4080 Mobile is the only choice with data. Its average score of 38,135 is over 12 times higher than the 5080 SUPER's 3,075, though this gap is an artifact of test selection. For users targeting the latest DX12 titles on a desktop, the 5080 SUPER offers a single data point that cannot be directly compared to the 4080 Mobile. The 5080 SUPER's higher core counts, memory capacity, and bandwidth suggest superior theoretical performance, but the database lacks the empirical scores to confirm this in a head-to-head context. The verdict is straightforward: the 4080 Mobile wins on breadth of testing and aggregate score, while the 5080 SUPER wins on raw specification and modern API representation, but neither can claim a definitive overall victory based on the recorded data.
