NVIDIA GeForce RTX 5090 vs NVIDIA P102-100 Comparison

Head-to-Head Benchmarks

The recorded data presents a stark contrast between these two NVIDIA offerings. In the two shared benchmark tests, the GeForce RTX 5090 dominates completely, securing victories in both Geekbench OpenCL and Geekbench Vulkan. The margin is not marginal; it is a generational chasm.

In Geekbench OpenCL, the RTX 5090 scores 334,370 points against the P102-100's 49,602. This translates to a delta of 574.1% in favor of the newer card. To put that in perspective, the RTX 5090 is not just faster, it is over six times faster in this compute-oriented test. The P102-100, despite its mining-focused design, does show some compute capability, but the sheer scale of the Blackwell architecture's FP32 throughput, 104.8 TFLOPS versus 10.77 TFLOPS, makes the outcome unsurprising.

The Vulkan results tell a similar story. The RTX 5090 achieves a score of 376,728, while the P102-100 manages 67,454. The delta here is 458.5%, again a decisive win for the RTX 5090. This test, which often reflects real-world gaming and graphics API performance, highlights the RTX 5090's modern feature set and raw execution power. The P102-100, with its Pascal architecture and lack of dedicated ray tracing or tensor cores, is simply outclassed in these API-bound workloads.

The win tally is clean: 2 wins for the RTX 5090, 0 for the P102-100. There are no benchmark tests where the P102-100 scores higher. This is a one-sided affair, and the data suggests that any comparison between these two for compute or graphics tasks will heavily favor the RTX 5090.

Where Each One Wins

Given the head-to-head results, the use-case split is stark. The RTX 5090 wins in every measured category. Its victories in Geekbench OpenCL and Vulkan indicate superiority in general-purpose compute (OpenCL) and modern graphics API workloads (Vulkan). The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s of bandwidth provide a massive foundation for large datasets and high-resolution textures, a clear advantage over the P102-100's 5 GB GDDR5X and 440.3 GB/s.

The P102-100, on the other hand, has no wins in the database. Its only benchmarks are the two Geekbench tests, both of which it loses. Its architecture, Pascal, is from a previous era, and its specifications reflect a purpose-built mining card: no display outputs, a PCIe 1.0 x4 interface, and a 250 W TDP. While it can perform compute tasks, the data shows it does so at a fraction of the RTX 5090's speed. For any modern workload, whether gaming, content creation, or AI inference, the RTX 5090 is the only logical choice based on the recorded benchmarks.

The P102-100's high percentile rank (88th vs the RTX 5090's 92nd) is interesting but misleading. This is likely due to its average benchmark score (58,528) being compared against a wide range of GPUs, including many older and weaker models. However, when directly compared to the RTX 5090, its relative weakness is laid bare. The RTX 5090's average score is 79,842, while its rival's is 58,528, further confirming the performance gap.

Architecture Differences

The architectural divide is fundamental. The RTX 5090 is built on the Blackwell 2.0 architecture, using the GB202 chip, fabricated on a 5 nm process at TSMC. The P102-100 uses the Pascal architecture with the GP102 chip, on a much older 16 nm process. This process node difference alone, 5 nm versus 16 nm, contributes significantly to the efficiency and density advantages of the newer card.

The transistor counts are revealing. The RTX 5090 packs 92,200 million transistors on a 750 mm² die, yielding a density of 122.9M transistors per mm². The P102-100 has 11,800 million transistors on a 471 mm² die, a density of just 25.1M per mm². The RTX 5090 is a monolithic powerhouse, while the P102-100 is a product of an older, less dense manufacturing era.

Feature-wise, the RTX 5090 is equipped with 170 ray tracing cores and 680 tensor cores, enabling hardware-accelerated ray tracing and AI-driven features like DLSS. The P102-100 has no RT cores and no tensor cores, making it incapable of these specialized tasks. Its 3,200 shading units, 200 TMUs, and 80 ROPs are dwarfed by the RTX 5090's 21,760 shading units, 680 TMUs, and 176 ROPs. The shader count alone is nearly seven times higher.

The memory subsystem also reflects the generational leap. The RTX 5090 uses GDDR7 on a 512-bit bus, achieving 1.79 TB/s. The P102-100 uses GDDR5X on a 320-bit bus, with 440.3 GB/s of bandwidth. This difference is critical for memory-bound workloads. The RTX 5090 also supports DirectX 12 Ultimate, while the P102-100 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the underlying hardware capabilities are worlds apart.

Specification Differences

The specification tables for the two cards differ in nearly every field. The most obvious is the memory configuration: 32 GB of GDDR7 on a 512-bit bus for the RTX 5090 versus 5 GB of GDDR5X on a 320-bit bus for the P102-100. Bandwidth follows suit, 1.79 TB/s versus 440.3 GB/s.

Clock speeds also diverge. The RTX 5090 has a base clock of 2017 MHz and a boost of 2407 MHz. The P102-100 operates at a base of 1582 MHz and a boost of 1683 MHz. While the P102-100's clocks are respectable for its era, they are significantly lower than the RTX 5090's.

Power and connectivity are another clear separator. The RTX 5090 has a TDP of 575 W and requires a 950 W power supply, using a single 16-pin connector. The P102-100 is rated at 250 W TDP, needs a 600 W PSU, and uses two 8-pin connectors. The bus interface differs: PCIe 5.0 x16 for the RTX 5090 versus PCIe 1.0 x4 for the P102-100, a bottleneck that severely limits data transfer for the older card. The RTX 5090 offers display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b), while the P102-100 has none, confirming its mining-only purpose. The RTX 5090's dimensions are 304 mm in length, 137 mm in height, and 40 mm in width. The P102-100 is 267 mm long, with no recorded height or width. Finally, the RTX 5090 has a launch MSRP of 1,999 USD; the P102-100 has no recorded launch MSRP.

The Verdict

The benchmark data is unequivocal. The GeForce RTX 5090 is the superior product in every measurable way. Its performance in the two shared tests is not just better, but overwhelmingly so, with deltas of 574.1% and 458.5%. For any user requiring high-end graphics, compute, or AI acceleration, the RTX 5090 is the clear choice.

The P102-100, by contrast, is an end-of-life product from a different era. Its strengths, if any, lie in its lower power draw of 250 W and its historical purpose as a mining card. However, the database shows no scenario where it outperforms the RTX 5090. Its lack of display outputs makes it unsuitable for standard desktop use, and its PCIe 1.0 x4 interface is a severe bottleneck.

Given the recorded data, the choice is simple. The RTX 5090, with its 92nd percentile ranking among all GPUs, is a top-tier performer. The P102-100, while ranking in the 88th percentile, is still a distant second in this comparison. The verdict is that the RTX 5090 is the only viable option for modern, demanding workloads. The P102-100 is a relic, and the numbers confirm it is not competitive.
