NVIDIA GeForce RTX 3080 Ti vs NVIDIA P102-100 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the NVIDIA GeForce RTX 3080 Ti dominates the NVIDIA P102-100 in every recorded test. Across the two shared workloads, the RTX 3080 Ti secures both victories, with the P102-100 failing to register a single win. The largest margin appears in Geekbench OpenCL, where the RTX 3080 Ti scores 170,037 against the P102-100's 49,602. That is a 70.8% deficit for the older chip, meaning the RTX 3080 Ti delivers roughly 3.4 times the compute performance in this workload. The Vulkan result tells a similar story: 192,697 for the RTX 3080 Ti versus 67,454 for the P102-100, a 65% gap. In both cases, the RTX 3080 Ti more than doubles the P102-100's output, and the consistency of these margins across different APIs suggests the performance gap is structural rather than workload-specific.

Looking beyond the head-to-head, the average benchmark scores place these cards in different tiers entirely. The P102-100 posts an average score of 58,528, which lands it in the 88th percentile of all GPUs in the database. The RTX 3080 Ti, despite its decisive head-to-head wins, has a lower average score of 41,187, placing it in the 83rd percentile. This apparent contradiction is explained by the different benchmark suites each card was subjected to. The P102-100's average is drawn from only two tests, both compute-oriented, while the RTX 3080 Ti's average includes a broader mix that pulls the mean down. When directly compared on identical workloads, the RTX 3080 Ti is the clear winner, and the percentile data should be read as a reflection of the test set, not the true performance relationship.

The nearest rival data for each card reinforces this divide. The P102-100 sits within 0.8% of the AMD Radeon PRO V710, RX 6950 XT, Intel Arc A570M, and RX 5600 OEM, all clustered around the 58,000 score mark. The RTX 3080 Ti, by contrast, sits near the AMD Radeon Pro 5300, NVIDIA Tesla M40 24 GB, and Tesla M40, with the RTX 5070 trailing by 2%. These are very different competitive neighborhoods, and the head-to-head numbers show that the P102-100 would be out of its depth against the RTX 3080 Ti.

Architecture Differences

The two GPUs come from different architectural eras. The P102-100 is built on the Pascal architecture with the GP102 chip, fabricated on a 16 nm process at TSMC. The RTX 3080 Ti uses the Ampere architecture with the GA102 chip, made on an 8 nm process at Samsung. The manufacturing node change is substantial: 16 nm down to 8 nm, which allows the newer chip to pack far more transistors into a similar physical footprint. The P102-100 contains 11,800 million transistors on a 471 mm² die, yielding a transistor density of 25.1 million per mm². The RTX 3080 Ti scales that up to 28,300 million transistors on a 628 mm² die, for a density of 45.1 million per mm². This is nearly double the density, and it shows in the raw specifications.

The compute resources are heavily skewed toward the RTX 3080 Ti. The P102-100 offers 3,200 shading units, 200 texture mapping units, and 80 render output units. The RTX 3080 Ti more than triples the shading units to 10,240, and brings 320 TMUs and 112 ROPs. The RTX 3080 Ti also introduces dedicated hardware that the P102-100 lacks entirely: 80 ray tracing cores and 320 tensor cores. These are absent from the Pascal chip, which predates the RTX era. The FP32 throughput tells the story clearly: 10.77 TFLOPS for the P102-100 versus 34.10 TFLOPS for the RTX 3080 Ti. The FP16 numbers are even more divergent. The P102-100 manages 168.3 GFLOPS at a 1:64 ratio, while the RTX 3080 Ti hits 34.10 TFLOPS at a 1:1 ratio. That 1:64 versus 1:1 ratio is a fundamental architectural change: Ampere processes half-precision at full rate, while Pascal treats it as a fraction of the FP32 path.

Memory is another major divider. The P102-100 uses 5 GB of GDDR5X on a 320-bit bus, delivering 440.3 GB/s of bandwidth. The RTX 3080 Ti steps up to 12 GB of GDDR6X on a 384-bit bus, with 912.4 GB/s. That is more than double the bandwidth, and it is paired with a larger frame buffer, which matters for modern workloads. The clock speeds are closer than the rest of the spec sheet might suggest. The P102-100 has a base clock of 1582 MHz and a boost of 1683 MHz, while the RTX 3080 Ti has a lower base of 1365 MHz but a similar boost of 1665 MHz. The RTX 3080 Ti compensates with far more parallel hardware, not higher clocks. The memory clocks differ in effective data rate: 11 Gbps for the P102-100 versus 19 Gbps for the RTX 3080 Ti.

The board designs reflect their intended uses. The P102-100 draws 250 W and requires a 600 W power supply, while the RTX 3080 Ti draws 350 W and needs a 750 W unit. Both are dual-slot cards, but the P102-100 has no display outputs at all, confirming its mining-focused design. The RTX 3080 Ti includes 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs, making it a fully functional consumer card. The bus interface also differs: the P102-100 runs on PCIe 1.0 x4, while the RTX 3080 Ti uses PCIe 4.0 x16. That is a significant bandwidth difference for host communication, though it matters less for compute-bound tasks. The P102-100 is 267 mm long, while the RTX 3080 Ti is 285 mm long, with a height of 112 mm and width of 40 mm.

The Verdict

The data supports only one conclusion for general use: the NVIDIA GeForce RTX 3080 Ti is the superior product. It wins every shared benchmark by a wide margin, offers more than triple the shading units, more than double the memory bandwidth, and adds ray tracing and tensor core support that the P102-100 cannot match. The P102-100 has a higher base clock and a slightly better percentile rank in the database, but neither compensates for the 70.8% and 65% deficits in direct comparison. The RTX 3080 Ti is the pick for anyone needing compute performance, modern API support, or display connectivity.

The P102-100 is not without a niche. Its 250 W power draw is 100 W lower than the RTX 3080 Ti's 350 W, and its 267 mm length makes it shorter than the 285 mm RTX 3080 Ti. It also uses the PCIe 1.0 x4 interface, which is unusual but irrelevant for mining workloads that do not rely on host bandwidth. For a task that only uses the compute units and does not need outputs, the P102-100 could be a lower-power alternative. However, the performance gap is so large that the RTX 3080 Ti completes any given compute task in a fraction of the time, and the power savings of the P102-100 would only matter if the workload is so light that the RTX 3080 Ti's extra speed is irrelevant. The recorded data offers no scenario where the P102-100 wins a benchmark, so the verdict is straightforward: the RTX 3080 Ti for virtually everything, the P102-100 only for power-constrained, compute-only tasks.

Where Each One Wins

The RTX 3080 Ti wins in every category where the two can be compared. In Geekbench OpenCL, it scores 170,037 versus 49,602, a 70.8% lead. In Geekbench Vulkan, it scores 192,697 versus 67,454, a 65% lead. The RTX 3080 Ti also wins on raw specifications: more shading units (10,240 vs 3,200), more TMUs (320 vs 200), more ROPs (112 vs 80), double the memory capacity (12 GB vs 5 GB), and more than double the bandwidth (912.4 GB/s vs 440.3 GB/s). It adds ray tracing cores and tensor cores, supports DirectX 12 Ultimate (12_2) versus DirectX 12 (12_1), and has PCIe 4.0 x16 versus PCIe 1.0 x4. The RTX 3080 Ti also has a higher pixel rate (186.5 GPixel/s vs 134.6 GPixel/s) and texture rate (532.8 GTexel/s vs 336.6 GTexel/s).

The P102-100's only advantages are its lower TDP (250 W vs 350 W) and its shorter length (267 mm vs 285 mm). It also has a higher base clock (1582 MHz vs 1365 MHz), though the boost clocks are nearly identical (1683 MHz vs 1665 MHz). The P102-100's 88th percentile rank in the database is higher than the RTX 3080 Ti's 83rd percentile, but that is an artifact of the different benchmark sets. In direct comparison, the P102-100 does not win a single recorded test. The use-case split is therefore clear: the RTX 3080 Ti is the choice for gaming, rendering, ray tracing, and any general-purpose compute workload. The P102-100 is only relevant for a mining-style workload that prioritizes lower power draw and does not require display output, where its lack of outputs and weaker compute are acceptable trade-offs.
