NVIDIA GeForce RTX 5070 SUPER vs NVIDIA GeForce RTX 5080 Mobile Comparison

Head-to-Head Benchmarks

The only shared benchmark between the two GPUs is 3DMark Steel Nomad DX12, and the result is decisive. The NVIDIA GeForce RTX 5080 Mobile scores 4952 points, while the NVIDIA GeForce RTX 5070 SUPER scores 2690 points. That puts the RTX 5080 Mobile ahead by 45.7%, a substantial margin in a modern DirectX 12 workload that stresses both rasterization and compute.

Benchmark results indicate the RTX 5080 Mobile lands in the 81st percentile among all GPUs in the database, while the RTX 5070 SUPER sits in the 18th percentile. This percentile gap is far larger than the raw score gap suggests, because the RTX 5080 Mobile is positioned near the upper tier of recorded GPUs while the RTX 5070 SUPER sits closer to the lower end of the distribution.

The RTX 5080 Mobile also carries a much broader benchmark record. Its average benchmark score across all recorded tests is 38349, which includes Geekbench OpenCL at 166986, Geekbench Vulkan at 169754, Passmark G3D at 27711, and Passmark GPU Compute at 12134. The RTX 5070 SUPER has only the single 3DMark Steel Nomad result, so its average benchmark score is 2690. The RTX 5080 Mobile's nearest rivals in the database include the NVIDIA GeForce RTX 4080 Mobile with an average score of 38135 and a delta of 0.6%, the NVIDIA GeForce MX570 at 38299 with a delta of 0.1%, and the AMD Radeon Pro 580X at 38706 with a delta of -0.9%. The RTX 5070 SUPER's nearest recorded rivals are far lower: the NVIDIA Quadro K1100M at 2664 with a 1% delta, the NVIDIA GeForce GT 1030 at 2662 with a 1.1% delta, and the Intel Arc Pro B50 at 2660 with a 1.1% delta.

In the head-to-head comparison, the RTX 5080 Mobile wins the single recorded benchmark outright. The delta of -45.7% in the database indicates the RTX 5070 SUPER's score is 45.7% lower than the RTX 5080 Mobile's score. This is not a close contest; the RTX 5080 Mobile delivers nearly double the 3DMark Steel Nomad performance of the RTX 5070 SUPER.

Architecture Differences

Both GPUs share the Blackwell 2.0 architecture and are fabricated on TSMC's 5 nm process, but their silicon implementations diverge significantly. The RTX 5070 SUPER uses the GB205 chip with 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3M per mm². The RTX 5080 Mobile uses the larger GB203 chip with 45,600 million transistors on a 378 mm² die, producing a transistor density of 120.6M per mm². The GB203 die is 43.7% larger by area and carries 46.6% more transistors, giving the RTX 5080 Mobile a substantially larger execution resource pool.

The shading unit counts reflect this difference. The RTX 5080 Mobile has 7680 shading units, 240 texture mapping units, and 96 render output units, compared to the RTX 5070 SUPER's 6400 shading units, 200 TMUs, and 80 ROPs. That is 1280 more shading units, 40 more TMUs, and 16 more ROPs on the mobile part. Ray tracing hardware follows the same pattern: the RTX 5080 Mobile has 60 RT cores versus 50, and 240 tensor cores versus 200.

Clock speeds tell a different story. The RTX 5070 SUPER has a base clock of 2325 MHz and a boost clock of 2512 MHz, while the RTX 5080 Mobile operates at a base clock of 975 MHz and a boost clock of 1500 MHz. The desktop part runs at far higher frequencies, which partially compensates for its smaller execution engine. The RTX 5070 SUPER achieves a pixel rate of 201.0 GPixel/s and a texture rate of 502.4 GTexel/s, while the RTX 5080 Mobile delivers 144.0 GPixel/s and 360.0 GTexel/s. In floating-point throughput, the RTX 5070 SUPER reaches 32.15 TFLOPS for both FP32 and FP16 (1:1), while the RTX 5080 Mobile reaches 23.04 TFLOPS for both. Despite having fewer shading units, the RTX 5070 SUPER's much higher clocks give it a 39.5% advantage in raw FP32 compute and a 39.5% advantage in texture fill rate.

Memory configurations also diverge. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus with a bandwidth of 672.0 GB/s. The RTX 5080 Mobile uses 16 GB of GDDR7 on a wider 256-bit bus with a bandwidth of 896.0 GB/s. The mobile part has 33.3% more memory bandwidth despite having 2 GB less capacity. Both run memory at 1750 MHz with 28 Gbps effective speed.

Power and physical characteristics differ sharply. The RTX 5070 SUPER has a TDP of 275 W, uses a dual-slot cooler with a 245 mm length, 115 mm height, and 40 mm width, and requires a single 16-pin power connector. The RTX 5080 Mobile has an 80 W TDP, is listed as an IGP (integrated graphics processor) with no power connector, and has no recorded dimensions. The RTX 5070 SUPER uses a 5 nm process node and was released on 2025-12-31T17:00:00.000Z, while the RTX 5080 Mobile was released earlier on 2025-04-01T17:00:00.000Z and lists the GeForce 40 Mobile as its predecessor.

Where Each One Wins

The RTX 5080 Mobile wins the only direct benchmark comparison, and its victory is decisive. The 45.7% lead in 3DMark Steel Nomad DX12 indicates that in modern DirectX 12 workloads, the mobile part delivers significantly higher frame throughput. Its 81st percentile ranking among all GPUs places it in the upper performance tier, while the RTX 5070 SUPER's 18th percentile ranking places it near the bottom of the distribution. The RTX 5080 Mobile also benefits from a wider memory bus, delivering 896.0 GB/s versus 672.0 GB/s, which helps in bandwidth-sensitive scenarios such as high-resolution texturing and ray tracing acceleration structures. Its larger execution engine, with 7680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores, provides more parallel throughput capacity when clock speeds are equalized.

The RTX 5070 SUPER wins on raw compute throughput despite losing the benchmark. Its FP32 output of 32.15 TFLOPS is 39.5% higher than the RTX 5080 Mobile's 23.04 TFLOPS, and its texture rate of 502.4 GTexel/s exceeds the mobile part's 360.0 GTexel/s by the same margin. The pixel rate also favors the desktop part at 201.0 GPixel/s versus 144.0 GPixel/s. These figures indicate that in workloads that scale with clock speed rather than core count, such as certain compute shaders or lightly threaded rendering paths, the RTX 5070 SUPER can outperform its mobile counterpart. Its 18 GB memory capacity also provides 2 GB more headroom for large datasets, and its dual-slot cooler with a 16-pin connector suggests sustained operation at higher power levels is possible. The RTX 5070 SUPER also supports direct display outputs with 1x HDMI 2.1b and 3x DisplayPort 2.1b, whereas the RTX 5080 Mobile's outputs are dependent on the host portable device.

The recorded data shows a clear split: the RTX 5080 Mobile is the stronger GPU for benchmark-driven performance, while the RTX 5070 SUPER offers higher theoretical compute rates and more memory capacity. The desktop part's higher clocks, at 2325 MHz base and 2512 MHz boost, more than compensate for its smaller core configuration in terms of raw throughput. The mobile part's lower clocks, at 975 MHz base and 1500 MHz boost, are offset by a larger execution engine and wider memory interface, which proves more effective in the single recorded 3DMark test. Users prioritizing the highest benchmark scores should favor the RTX 5080 Mobile; those needing maximum FP32 compute or additional memory capacity should consider the RTX 5070 SUPER.
