NVIDIA GeForce RTX 4080 vs NVIDIA GeForce RTX 5050 Mobile Comparison

The Verdict

The data in this comparison is decisively one-sided. The NVIDIA GeForce RTX 4080 outperforms the NVIDIA GeForce RTX 5050 Mobile in every recorded benchmark, taking both head-to-head tests with a 2-0 win tally. The desktop-class RTX 4080, built on the Ada Lovelace architecture with the AD103 chip, is in a completely different performance tier than the mobile-focused RTX 5050 Mobile, which uses the Blackwell 2.0 architecture and the GB207 chip.

The average benchmark scores tell the story clearly: the RTX 4080 posts an average score of 54,247, while the RTX 5050 Mobile averages 43,268. That is a substantial gap, but the more striking separation appears in individual tests. In 3DMark Steel Nomad DX12, the RTX 4080 scores 6,567 against just 2,365 for the RTX 5050 Mobile, a delta of 177.7% in favor of the desktop card. The Geekbench OpenCL test shows a slightly narrower margin at 155.1%, with the RTX 4080 reaching 214,739 points compared to 84,171 for the mobile chip.

For desktop users considering which GPU to pick, the RTX 4080 is the obvious choice if raw performance is the priority. The RTX 4080 sits at the 86th percentile among all GPUs in the database, and it lands within 0.1% of the RTX 4080 SUPER in average score, with a delta of 0.1. That positions it right alongside its direct desktop sibling, which is notable company. The RTX 4080 is within 1.1% of the AMD Radeon Pro W5700X, and those rivals are the closest neighbors in its percentile range.

The RTX 5050 Mobile, meanwhile, anchors at the 83rd percentile across all GPUs. It posts a delta of 0.0 against the NVIDIA Quadro M6000 and lands within 0.1% of the RTX 4070 SUPER. Curiously, the RTX 5050 Mobile also sits within 0.9% of the RTX 4090 Mobile in its rival list, which places it in respectable mobile territory, even if it cannot approach the desktop RTX 4080.

The verdict is that these two cards serve entirely different segments. The RTX 4080 is an end-of-life desktop part with a launch MSRP of 1,199 USD, and it dominates the benchmarks. The RTX 5050 Mobile is an active, current-generation mobile part with no launch MSRP recorded, and while it trails far behind in this matchup, its percentile placement suggests it holds its own within the mobile landscape.

Architecture Differences

The RTX 4080 uses the AD103 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The RTX 5050 Mobile uses the GB207 chip with the Blackwell 2.0 architecture, also made by TSMC on the same 5 nm process node. Both cards share identical API support, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The transistor counts diverge sharply. The RTX 4080 packs 45,900 million transistors across a die size of 379 mm², giving it a transistor density of 121.1M per mm². The RTX 5050 Mobile contains 16,900 million transistors on a much smaller 149 mm² die, resulting in a density of 113.4M per mm². The desktop card carries nearly three times the transistor budget, which translates directly into its massive advantage in compute resources.

The RTX 4080 features 9,728 shading units, 304 texture mapping units, and 112 render output units. It also includes 76 ray tracing cores and 304 tensor cores. The RTX 5050 Mobile is far leaner, with 2,560 shading units, 80 TMUs, 32 ROPs, 20 ray tracing cores, and 80 tensor cores. The desktop card has roughly 3.8 times the shading units and the same multiplier applies to its TMU and tensor core counts, while its ROP count is 3.5 times higher.

The memory architecture differs as well. The RTX 4080 uses 16 GB of GDDR6X memory on a 256-bit bus, while the RTX 5050 Mobile uses 8 GB of GDDR7 memory on a 128-bit bus. The memory technology is newer on the mobile part, but the desktop card compensates with twice the capacity and double the bus width. The RTX 4080 is an end-of-life product, released on September 19, 2022, with its predecessor being the GeForce 30 series and its successor the GeForce 50 series. The RTX 5050 Mobile is an active product released on June 23, 2025, with the GeForce 40 Mobile as its predecessor and no successor listed.

Specification Differences

The clock speeds differ substantially. The RTX 4080 runs at a base clock of 2205 MHz and a boost clock of 2505 MHz, while the RTX 5050 Mobile operates at a 1020 MHz base and 1500 MHz boost. The memory clocks are 1400 MHz with 22.4 Gbps effective for the RTX 4080, versus 1500 MHz with 24 Gbps effective for the RTX 5050 Mobile. Despite the mobile card's faster memory clock, the RTX 4080 achieves 716.8 GB/s of bandwidth against 384.0 GB/s for the mobile part, thanks to its wider bus.

The power profile is a major separator. The RTX 4080 has a TDP of 320 W, while the RTX 5050 Mobile draws just 50 W. The RTX 4080 requires a triple-slot cooler and a 1x 16-pin power connector, plus a suggested PSU of 700 W. The RTX 5050 Mobile is an IGP-class part with no power connectors and no suggested PSU listed. The desktop card measures 310 mm in length, 140 mm in height, and 61 mm in width, while the mobile chip has no recorded dimensions.

The RTX 4080 uses a PCIe 4.0 x16 bus interface and offers display outputs of 1x HDMI 2.1 and 3x DisplayPort 1.4a. The RTX 5050 Mobile uses the newer PCIe 5.0 x16 interface but its display outputs are listed as portable device dependent. The RTX 4080 has a launch MSRP of 1,199 USD, while the RTX 5050 Mobile has no launch MSRP recorded. The production statuses also differ, with the RTX 4080 marked end-of-life and the RTX 5050 Mobile active.

Head-to-Head Benchmarks

The two recorded head-to-head tests both go to the RTX 4080, and the margins are enormous. In 3DMark Steel Nomad DX12, the RTX 4080 scores 6,567 against 2,365 for the RTX 5050 Mobile. That is a delta of 177.7%, meaning the desktop card outperforms the mobile chip by nearly a factor of three in this DirectX 12 workload. This test is the largest win for the RTX 4080 in the comparison, and it reflects the massive gap in raw compute resources between the two parts.

Geekbench OpenCL shows a similar story, though the margin tightens slightly. The RTX 4080 posts 214,739 points against 84,171 for the RTX 5050 Mobile, a 155.1% delta. This test measures general-purpose compute performance, and the RTX 4080's 48.74 TFLOPS of FP32 throughput against just 7.680 TFLOPS for the mobile card explains the result. The RTX 4080 also leads in pixel rate at 280.6 GPixel/s versus 48.00 GPixel/s, and in texture rate at 761.5 GTexel/s versus 120.0 GTexel/s.

The RTX 4080's broader benchmark suite in the database includes additional tests: PassMark DirectX 10 at 204, DirectX 11 at 314, DirectX 12 at 132, DirectX 9 at 370, G2D at 1239, G3D at 34,457, and GPU Compute at 20,671. The RTX 5050 Mobile only has the two head-to-head results recorded, so the comparison rests on those two tests. In both, the RTX 4080 wins with deltas exceeding 150%.

The RTX 4080 also holds a clear advantage in its rival positioning. It sits at the 86th percentile compared to the 83rd for the RTX 5050 Mobile. The RTX 4080's nearest rival, the RTX 4080 SUPER, averages 54,209, a delta of 0.1%, meaning the two desktop cards are effectively inseparable. The RTX 5050 Mobile's nearest rival, the Quadro M6000, averages 43,262, a delta of 0.0%, showing the mobile card is well matched with that workstation part. The RTX 5050 Mobile also comes within 0.9% of the RTX 4090 Mobile, which places it near the top of the mobile stack, but that context does little to close the chasm between it and the desktop RTX 4080.
