NVIDIA GeForce RTX 5080 Mobile vs NVIDIA P104-100 Comparison

NVIDIA GeForce RTX 5080 Mobile vs NVIDIA P104-100: the database pits a current-generation Blackwell 2.0 laptop GPU against a Pascal-based mining card from 2017. The recorded benchmarks show a complete sweep in favor of the RTX 5080 Mobile, but the P104-100 still holds relevance as a data point for how far GPU architecture has shifted.

Head-to-Head Benchmarks

The three shared benchmark results are unambiguous. In 3DMark Steel Nomad (DX12), the RTX 5080 Mobile scores 4952 against the P104-100's 1413, a delta of 250.5%. That is not a marginal lead; it is a three-and-a-half-fold advantage in raw rasterization throughput. The Geekbench OpenCL test shows 166986 versus 52368, a 218.9% gap, indicating the RTX 5080 Mobile also dominates compute workloads that rely on general-purpose shader execution. The most extreme discrepancy appears in Geekbench Vulkan: 169754 versus 45165, a 275.9% delta. Vulkan's low-level API overhead tends to reward newer hardware with better driver optimization and hardware scheduling, and the data reflects that.

Every head-to-head win goes to the RTX 5080 Mobile, three wins to zero. The P104-100 does not come close in any metric. Looking at the wider database context, the RTX 5080 Mobile's average benchmark score is 38349, placing it in the 81st percentile of all GPUs. Its nearest rivals include the GeForce MX570 (38299, +0.1%), RTX 4080 Mobile (38135, +0.6%), and MX570 A (38691, -0.9%). The P104-100, with an average score of 32982, sits in the 77th percentile, near the T600 Mobile (32849, +0.4%), T550 Mobile (33161, -0.5%), and RTX 3050 Mobile (33170, -0.6%). The percentile gap is modest, but the absolute score difference of 5367 points between the two cards is substantial.

Architecture Differences

The two GPUs come from entirely different design eras. The RTX 5080 Mobile uses the GB203 chip built on Blackwell 2.0 architecture at a 5 nm process node from TSMC. The P104-100 uses the GP104 chip on the older Pascal architecture at a 16 nm node, also from TSMC. The transistor counts reflect the generational leap: the GB203 packs 45,600 million transistors on a 378 mm² die, yielding a density of 120.6 million transistors per mm². The GP104 has 7,200 million transistors on a 314 mm² die, for a density of 22.9 million per mm². The RTX 5080 Mobile is not just faster; it is denser by a factor of roughly five.

Core configuration differences are stark. The RTX 5080 Mobile has 7680 shading units, 240 TMUs, and 96 ROPs, plus 60 ray tracing cores and 240 tensor cores. The P104-100 has 1920 shading units, 120 TMUs, and 64 ROPs, with no ray tracing or tensor cores at all. That means the RTX 5080 Mobile carries four times the shader count, double the TMUs, and 50% more ROPs. The P104-100's lack of dedicated RT and tensor hardware makes it entirely incapable of hardware-accelerated ray tracing or AI-accelerated workloads, whereas the RTX 5080 Mobile is built around those features.

Clock speeds tell a different story. The P104-100 runs a base clock of 1607 MHz and boost of 1733 MHz, while the RTX 5080 Mobile runs a base of 975 MHz and boost of 1500 MHz. The older card has higher raw clocks, but the newer card's massive core count and architectural efficiency more than compensate. Memory technology also diverges: the RTX 5080 Mobile uses 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s bandwidth, while the P104-100 uses 4 GB of GDDR5X on the same bus width, yielding 320.3 GB/s. The memory speed difference is similarly large, with the RTX 5080 Mobile at 1750 MHz (28 Gbps effective) and the P104-100 at 1251 MHz (10 Gbps effective).

Pixel and texture rates reinforce the gap. The RTX 5080 Mobile outputs 144.0 GPixel/s and 360.0 GTexel/s, versus the P104-100's 110.9 GPixel/s and 208.0 GTexel/s. FP32 compute is 23.04 TFLOPS for the RTX 5080 Mobile versus 6.655 TFLOPS for the P104-100. FP16 is even more lopsided: the RTX 5080 Mobile achieves 23.04 TFLOPS at a 1:1 ratio, while the P104-100 manages only 104.0 GFLOPS at a 1:64 ratio, a 221-fold difference in raw half-precision throughput.

The Verdict

The data points to a clear conclusion for any workload represented in these benchmarks. The RTX 5080 Mobile is the superior GPU for 3D rendering, compute, and API-level performance. Its 250.5% lead in 3DMark Steel Nomad, 218.9% lead in OpenCL, and 275.9% lead in Vulkan leave no ambiguity. Anyone needing modern graphics features, high memory capacity, or ray tracing capability should choose the RTX 5080 Mobile without hesitation.

The P104-100, however, is not without a niche. Its 77th percentile ranking and average score of 32982 mean it still outperforms a significant portion of the GPU population, and its nearest rivals are all mobile or pro cards with similar scores. For workloads that predate DX12 Ultimate, or for systems where a dual-slot, 8-pin powered card with no display outputs is acceptable, the P104-100 can still function as a compute-only accelerator. But the absence of RT cores, tensor cores, and modern memory technology makes it a legacy part.

Who should pick which? The RTX 5080 Mobile is for anyone running current games, DX12 Ultimate titles, or compute tasks that benefit from FP32 or FP16 throughput. The P104-100 is for niche mining or headless compute scenarios where its 4 GB GDDR5X and 320.3 GB/s bandwidth are sufficient, and where the 200 W suggested PSU and PCIe 1.0 x4 interface are not bottlenecks. The database does not record a single test where the P104-100 wins, so any choice favoring it must rest on compatibility or power constraints, not performance.

The P104-100 also has a 267 mm (10.5 inches) length, while the RTX 5080 Mobile has no recorded dimensions.

Where Each One Wins

The RTX 5080 Mobile wins in every benchmark category the database records. In 3DMark Steel Nomad DX12, its 4952 score represents the modern gaming and rendering workload, where the P104-100's 1413 is a distant second. In Geekbench OpenCL and Vulkan, the RTX 5080 Mobile's 166986 and 169754 scores show compute and graphics API versatility that the P104-100 cannot match with its 52368 and 45165 scores. The RTX 5080 Mobile also wins on memory capacity, bandwidth, feature set, and efficiency, with an 80 W TDP versus the P104-100's unspecified power draw but dual-slot cooler and 200 W PSU recommendation.

The P104-100's only theoretical advantages come from its physical and interface design. It is a dual-slot card with a 267 mm length, which fits standard desktop chassis, whereas the RTX 5080 Mobile is an IGP with no discrete dimensions. The P104-100 uses a PCIe 1.0 x4 interface, which is older but potentially compatible with legacy systems, while the RTX 5080 Mobile requires PCIe 5.0 x16. The P104-100 has a single 8-pin power connector and no display outputs, making it suitable for headless compute or mining rigs. None of these advantages translate into benchmark wins, but they define the P104-100's use case as a specialized, legacy accelerator rather than a general-purpose GPU. For any task measured in the database, the RTX 5080 Mobile is the definitive choice.
