Where Each One Wins

The benchmark data shows a clear split in where each GPU excels, driven primarily by the nature of the available tests. The RTX 5070 Mobile dominates in legacy and general-purpose workloads, while the RTX 5080 SUPER is only represented in a single modern DirectX 12 test.

The RTX 5070 Mobile wins in every recorded category for which it has data. Its Passmark G3D score of 20355 represents the strongest overall graphics result among its nine benchmarks. In compute-oriented tasks, the Passmark GPU Compute score of 8279 shows substantial throughput, and the Geekbench OpenCL score of 122238 confirms strong general-purpose compute performance. The Geekbench Vulkan score of 116960 indicates capable modern API performance as well. Legacy DirectX tests also favor the 5070 Mobile, with scores of 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12. The Passmark G2D score of 896 reflects 2D rendering capability.

The RTX 5080 SUPER has exactly one recorded benchmark: 3DMark Steel Nomad DX12, where it scores 3075. This single data point prevents direct head-to-head comparison with the 5070 Mobile, which has no recorded result for that specific test. The database therefore shows zero wins for each GPU in direct head-to-head benchmarks, as no shared test exists between the two products.

The use-case split is therefore based on test coverage rather than overlapping performance. The RTX 5070 Mobile demonstrates versatility across multiple API generations and compute workloads, making it a general-purpose graphics solution for portable systems. The RTX 5080 SUPER, with only a modern DirectX 12 result, is positioned for high-end desktop workloads where that specific benchmark is relevant. The 5080 SUPER also holds a performance percentile of 19 among all GPUs, while the 5070 Mobile holds a percentile of 75, indicating that the 5070 Mobile ranks higher relative to the broader GPU population in the database.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture, but they are built on different chips with distinct resource configurations. The RTX 5070 Mobile uses the GB206 chip, while the RTX 5080 SUPER uses the GB203 chip. The transistor counts differ substantially: the GB206 contains 21,900 million transistors on a die size of 181 mm², while the GB203 contains 45,600 million transistors on a die size of 378 mm². Transistor density is nearly identical, with the 5070 Mobile at 121.0M per mm² and the 5080 SUPER at 120.6M per mm², indicating that the process node and design methodology are consistent across both chips.

The shading engine resources scale with the larger chip. The RTX 5070 Mobile has 4608 shading units, 144 texture mapping units, and 48 render output units. The RTX 5080 SUPER more than doubles these figures, with 10752 shading units, 336 texture mapping units, and 112 render output units. Ray tracing cores follow the same pattern: 36 on the 5070 Mobile versus 84 on the 5080 SUPER. Tensor cores scale identically, with 144 on the 5070 Mobile and 336 on the 5080 SUPER.

The compute rates reflect these resource differences. The RTX 5070 Mobile delivers 13.13 TFLOPS for both FP32 and FP16 (1:1 ratio), a pixel rate of 68.40 GPixel/s, and a texture rate of 205.2 GTexel/s. The RTX 5080 SUPER delivers 56.28 TFLOPS for both FP32 and FP16, a pixel rate of 293.1 GPixel/s, and a texture rate of 879.3 GTexel/s. The 5080 SUPER therefore provides roughly 4.3 times the FP32 throughput, 4.3 times the pixel rate, and 4.3 times the texture rate of the 5070 Mobile.

Memory architecture also differs beyond capacity. The 5070 Mobile uses a 128-bit memory bus with 8 GB of GDDR7 and achieves 384.0 GB/s bandwidth. The 5080 SUPER uses a 256-bit bus with 24 GB of GDDR7 and achieves 1.02 TB/s bandwidth. The effective memory clock is 1500 MHz (24 Gbps effective) on the 5070 Mobile versus 2000 MHz (32 Gbps effective) on the 5080 SUPER.

Specification Differences

The physical and power specifications show the two GPUs occupy opposite ends of the mobile-to-desktop spectrum. The RTX 5070 Mobile is classified as an IGP (integrated graphics processor) with no slot width and no power connectors, reflecting its integration into portable devices. Its display outputs are listed as "Portable Device Dependent," meaning the output configuration is determined by the host device. The RTX 5080 SUPER is a dual-slot card with dimensions of 304 mm in length, 137 mm in height, and 40 mm in width, and it requires a single 16-pin power connector. Its display outputs are fixed: 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Power consumption diverges sharply. The RTX 5070 Mobile has a 50 W TDP, while the RTX 5080 SUPER has a 415 W TDP, an eightfold difference. Both use the PCIe 5.0 x16 bus interface. The release dates differ: the RTX 5070 Mobile was released on 2025-04-14, while the RTX 5080 SUPER was released on 2025-12-31. The 5080 SUPER carries a launch MSRP of 999 USD; the 5070 Mobile has no recorded launch MSRP. The 5070 Mobile lists its predecessor as GeForce 40 Mobile, while the 5080 SUPER has no predecessor recorded in the database.

Production status for both is Active. The 5070 Mobile belongs to the GeForce 50 Mobile generation, while the 5080 SUPER belongs to the GeForce 50 generation, indicating the latter is positioned as a desktop product. The chip, transistor count, die size, shading units, texture units, ROPs, ray tracing cores, tensor cores, clock speeds, memory size, bus width, bandwidth, TDP, and physical dimensions all differ between the two, as enumerated above.

Head-to-Head Benchmarks

The database records no shared benchmark tests between the RTX 5070 Mobile and the RTX 5080 SUPER, so there are no direct head-to-head scores to compare. Instead, each GPU stands alone in its respective test set. The RTX 5070 Mobile has nine benchmarks, while the RTX 5080 SUPER has one.

For the RTX 5070 Mobile, the largest recorded scores are in compute-oriented tests. The Geekbench OpenCL score of 122238 is the highest single result, followed by the Geekbench Vulkan score of 116960. Among Passmark tests, the G3D score of 20355 leads, with GPU Compute at 8279 and G2D at 896. The DirectX legacy tests show lower magnitudes: DirectX 9 scores 214, DirectX 11 scores 192, DirectX 10 scores 129, and DirectX 12 scores 93. These figures indicate that the GPU performs strongest in modern compute APIs and weaker in older rasterization workloads, which is consistent with its architecture generation.

The RTX 5080 SUPER's sole benchmark, 3DMark Steel Nomad DX12, scores 3075. This test is a modern DirectX 12 workload, and the score places the GPU at the 19th percentile among all GPUs in the database. The nearest rivals for the 5080 SUPER in the database include the NVIDIA Quadro P1000, which scores 3163 (2.8% higher), and the Intel Arc Pro B60, which scores 3182 (3.4% higher). The 5080 SUPER leads the NVIDIA GeForce 820A by 3.1% (2983) and the NVIDIA GeForce GTX 860M by 3.6% (2967). These comparisons are based on average benchmark scores, but the sparse data for the 5080 SUPER limits the statistical weight of these deltas.

For the RTX 5070 Mobile, the nearest rivals are all higher-end desktop or mobile GPUs from prior generations. The AMD Radeon RX 6700 leads by 1.7% with a score of 30433, the AMD Radeon RX 6800 leads by 0.6% with 30095, and the NVIDIA GeForce RTX 3070 Ti leads by 0.1% with 29945. The RTX 5070 Mobile leads the NVIDIA GeForce RTX 2080 Ti by 0.5%, with the latter scoring 29783. These margins are all within 2 percentage points, indicating that the 5070 Mobile performs in a similar class to these established GPUs despite its lower TDP and mobile form factor.

The average benchmark score for the 5070 Mobile is 29928, which is significantly higher than the 5080 SUPER's 3075. However, this difference is not meaningful for direct comparison because the test suites are entirely different. The 5070 Mobile's average includes legacy and compute workloads, while the 5080 SUPER's single result comes from a modern DirectX 12 test. The data indicates that the 5080 SUPER lacks coverage in the broader benchmark suite, making its aggregate statistics less representative of its overall capability. The 5070 Mobile, with nine tests spanning multiple APIs, provides a more complete performance profile.
