NVIDIA GeForce RTX 5080 Mobile vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The database contains a full benchmark profile for the NVIDIA GeForce RTX 5080 Mobile, while the RTX 5090 SE has no recorded benchmark scores. This asymmetry means direct numerical comparisons are limited to the architectural specifications and the 5080 Mobile's measured performance against its nearest rivals.

The RTX 5080 Mobile delivers an average benchmark score of 38,349 across all recorded tests. This places it at the 81st percentile among all GPUs in the database. Its closest rival is the NVIDIA GeForce MX570, which averages 38,299, a delta of just 0.1%. The RTX 4080 Mobile follows closely at 38,135, which is 0.6% behind the 5080 Mobile. The AMD Radeon Pro 580X scores 38,706, putting it 0.9% ahead of the 5080 Mobile, while the MX570 A also sits 0.9% ahead with 38,691.

In specific workloads, the 5080 Mobile shows notable strengths. Its 3DMark Steel Nomad DX12 score is 4,952, reflecting strong modern DirectX 12 gaming performance. The Geekbench OpenCL score reaches 166,986, while the Vulkan score is 169,754, indicating robust compute and graphics API support. PassMark results show a G3D score of 27,711, a G2D score of 1,095, and a GPU compute score of 12,134. Legacy DirectX tests show 314 in DX9, 253 in DX11, 171 in DX10, and 116 in DX12, with the DX12 score notably lower than the 3DMark result, suggesting different workload characteristics across test suites.

The RTX 5090 SE, by contrast, has no recorded benchmark entries, an average score of 0, and a 50th percentile ranking across all GPUs, which reflects the absence of data rather than actual performance. Its nearest rivals list is empty, so no comparative deltas exist for this part.

Where Each One Wins

The RTX 5080 Mobile wins in mobility and power efficiency. It carries an 80 W TDP with no power connectors and an IGP slot width, making it suitable for thin-and-light laptops. Its 5 nm process node, TSMC foundry, and 45,600 million transistors on a 378 mm² die yield a transistor density of 120.6M per mm². The 5080 Mobile offers 16 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. It operates at a base clock of 975 MHz and a boost clock of 1500 MHz, with memory at 1750 MHz (28 Gbps effective). The 7,680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores produce 23.04 TFLOPS FP32 and FP16 performance, with pixel rate of 144.0 GPixel/s and texture rate of 360.0 GTexel/s.

The RTX 5090 SE wins in raw compute and memory capacity. It uses the GB202 chip with 92,200 million transistors on a 750 mm² die, a transistor density of 122.9M per mm². It features 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. Its FP32 and FP16 throughput is 66.94 TFLOPS each, with pixel rate of 380.3 GPixel/s and texture rate of 1,045.9 GTexel/s. The 5090 SE carries 24 GB of GDDR7 memory on a 384-bit bus, achieving 1.34 TB/s bandwidth. Base clock is 1,740 MHz and boost is 2,377 MHz, with memory at 1750 MHz (28 Gbps effective). It draws 500 W TDP, requires a 1x 16-pin power connector, and a suggested 900 W PSU. It supports dual-slot mounting and dimensions of 267 mm length, 111 mm height, and 40 mm width.

For workloads, the 5080 Mobile is the only one with measured data. Its PassMark G3D score of 27,711 and 3DMark Steel Nomad score of 4,952 indicate solid gaming capability for a mobile part. The Geekbench scores suggest strong compute for OpenCL and Vulkan applications. The 5090 SE, based on its specifications, would deliver substantially higher raw performance, but the database contains no benchmark confirmations.

The Verdict

The data shows two distinct product categories. The RTX 5080 Mobile is a laptop GPU with verified performance across multiple benchmarks, achieving an 81st percentile rank and an average score of 38,349. Its nearest rival deltas are minimal, ranging from -0.9% to +0.6%, meaning it sits in a tight competitive cluster with the MX570, MX570 A, RTX 4080 Mobile, and Radeon Pro 580X. The 5080 Mobile is the only part in this comparison with actual benchmark results, so any performance assessment must rely solely on its recorded scores.

The RTX 5090 SE has no recorded benchmarks, an average score of 0, and a 50th percentile rank, which is a placeholder reflecting missing data. Its specifications indicate a much larger GPU: nearly double the transistors, nearly double the shading units, 50% more memory, and nearly 50% more bandwidth. The FP32 throughput of 66.94 TFLOPS is roughly 2.9 times the 5080 Mobile's 23.04 TFLOPS. The 5090 SE also carries a launch MSRP of 1,499 USD, while the 5080 Mobile has no listed launch price.

For users requiring a portable solution with measured performance, the RTX 5080 Mobile is the only option with data. For users seeking maximum compute and memory capacity in a desktop form factor, the RTX 5090 SE offers superior specifications, but the database lacks verification of its actual performance. The choice depends on whether measured results or raw specifications take priority, and the data cannot confirm the 5090 SE's real-world standing.
