NVIDIA GeForce RTX 3080 Ti Mobile vs NVIDIA P106-100 Comparison

The Verdict

The recorded data presents a decisive outcome: the NVIDIA GeForce RTX 3080 Ti Mobile wins all three shared benchmark tests against the NVIDIA P106-100. The average benchmark score for the RTX 3080 Ti Mobile is 25740, placing it in the 71st percentile of all GPUs, while the P106-100 averages 23249, sitting in the 68th percentile. This 10.7% gap in average score, combined with the massive deltas in individual tests, makes the RTX 3080 Ti Mobile the clear choice for any workload that can utilize its feature set.

The RTX 3080 Ti Mobile is the pick for users running modern DirectX 12 Ultimate workloads, compute-heavy applications via OpenCL, or Vulkan-based titles. Its 3dmark Steel Nomad DX12 score of 2869 is 219.1% higher than the P106-100's 899, a gap that reflects not just raw compute but architectural maturity. The Geekbench OpenCL result of 117866 versus 35951, a 227.9% advantage, reinforces this direction.

The P106-100, however, is a specialized product. It has no display outputs, a PCIe 1.0 x16 bus interface, and a 120 W TDP with a 1x 6-pin power connector. Its intended role is mining, not general desktop use. The data shows it is competitive within its own peer group: its average score of 23249 sits within 0.1% of the AMD Radeon Pro Vega 16, and it trails the AMD Radeon RX 6600M by a negligible 0.1%. But against the RTX 3080 Ti Mobile, it is outclassed in every measurable way.

For a user with a portable device that supports the RTX 3080 Ti Mobile, the verdict is straightforward: the mobile Ampere part delivers roughly three times the performance in the three recorded tests. For a user constrained to a mining-specific card with no video outputs, the P106-100 remains a functional, if dated, compute device, but it cannot be recommended for any visual or gaming workload given the lack of display connectivity.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The RTX 3080 Ti Mobile uses the GA103 chip on the Ampere architecture, built on an 8 nm Samsung process. It integrates 22,000 million transistors on a 496 mm² die, yielding a transistor density of 44.4M per mm². The P106-100 uses the GP106 chip on the Pascal architecture, fabricated on a 16 nm TSMC process. It packs 4,400 million transistors on a 200 mm² die, with a density of 22.0M per mm². The Ampere part has five times the transistor count and more than double the die area.

Memory subsystems differ substantially. The RTX 3080 Ti Mobile ships with 16 GB of GDDR6 on a 256 bit bus, delivering 512.0 GB/s of bandwidth. The P106-100 has 6 GB of GDDR5 on a 192 bit bus, with 192.2 GB/s of bandwidth. The memory clock for the RTX 3080 Ti Mobile is 2000 MHz with 16 Gbps effective, while the P106-100 runs at 2002 MHz with 8 Gbps effective. The bandwidth advantage of the RTX 3080 Ti Mobile is roughly 2.7 times.

Compute resources follow the same pattern. The RTX 3080 Ti Mobile has 7424 shading units, 232 TMUs, and 96 ROPs. It also includes 58 RT cores and 232 tensor cores, reflecting its Ampere design. The P106-100 has 1280 shading units, 80 TMUs, and 48 ROPs, with no RT cores and no tensor cores. The RTX 3080 Ti Mobile's FP32 throughput is 18.71 TFLOPS, while the P106-100 manages 4.375 TFLOPS. FP16 performance is even more lopsided: the Ampere part delivers 18.71 TFLOPS at a 1:1 ratio, while the Pascal part delivers only 68.36 GFLOPS at a 1:64 ratio.

Clock speeds tell a different story. The P106-100 runs at a 1506 MHz base and 1709 MHz boost, much higher than the RTX 3080 Ti Mobile's 810 MHz base and 1260 MHz boost. This is expected, as the Ampere mobile chip is designed for a lower 115 W TDP, while the P106-100 has a 120 W TDP. The higher clocks of the Pascal part cannot compensate for the massive difference in shader count and memory bandwidth.

API support also differs. The RTX 3080 Ti Mobile supports DirectX 12 Ultimate (12_2), while the P106-100 supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The bus interface is PCIe 4.0 x16 for the RTX 3080 Ti Mobile versus PCIe 1.0 x16 for the P106-100, which limits data transfer rates on the older card.

Physical and power characteristics diverge. The RTX 3080 Ti Mobile has no power connectors, as it is designed for portable devices with integrated power delivery. The P106-100 is a dual-slot card, 250 mm or 9.8 inches long, requiring a single 6-pin connector and a 300 W suggested power supply. The P106-100 has no display outputs, while the RTX 3080 Ti Mobile's outputs are portable device dependent.

Where Each One Wins

The RTX 3080 Ti Mobile wins in every recorded benchmark category. In 3dmark Steel Nomad DX12, it scores 2869 against 899, a 219.1% lead. This test exercises modern DirectX 12 rendering paths, where the Ampere architecture's dedicated RT cores and tensor cores provide a structural advantage. The P106-100, lacking these units, falls far behind.

In Geekbench OpenCL, the RTX 3080 Ti Mobile scores 117866 versus 35951, a 227.9% delta. This is a compute-heavy test that rewards raw FP32 throughput and memory bandwidth. The Ampere part's 18.71 TFLOPS and 512.0 GB/s bandwidth are decisive. The Pascal part's 4.375 TFLOPS and 192.2 GB/s bandwidth cannot compete.

In Geekbench Vulkan, the RTX 3080 Ti Mobile scores 107502 versus 32897, a 226.8% delta. Vulkan workloads benefit from the same compute and bandwidth advantages, plus the newer architecture's improved draw call handling. The P106-100's higher clock speeds do not translate into a win here.

The P106-100's strengths, such as they are, lie outside the shared benchmark set. It has a higher boost clock of 1709 MHz, a lower transistor count that implies lower manufacturing complexity, and a 120 W TDP that is only 5 W higher than the RTX 3080 Ti Mobile despite the performance gap. It also has a 250 mm length and a dual-slot form factor, which makes it physically installable in standard desktop cases, whereas the RTX 3080 Ti Mobile is a mobile part.

For use cases, the RTX 3080 Ti Mobile is suited for portable gaming laptops, content creation on the go, and any workload that leverages DirectX 12 Ultimate features or ray tracing. The P106-100, with no display outputs, is limited to compute or mining tasks where video output is irrelevant. Its Pascal architecture still supports OpenGL 4.6 and Vulkan 1.4, but the lack of RT and tensor cores removes it from consideration for modern AI or ray-traced workloads.

Head-to-Head Benchmarks

The three shared benchmarks all favor the RTX 3080 Ti Mobile by wide margins. The smallest delta is in 3dmark Steel Nomad DX12, where the RTX 3080 Ti Mobile scores 2869 against 899, a 219.1% difference. This test is designed for modern DirectX 12 hardware, and the Ampere part's RT cores and 12_2 feature level give it a clear edge. The P106-100's 12_1 support and lack of dedicated ray tracing hardware put it at a structural disadvantage.

Geekbench OpenCL shows the largest delta at 227.9%. The RTX 3080 Ti Mobile's 117866 score dwarfs the P106-100's 35951. This test stresses general compute, where the Ampere part's 18.71 TFLOPS FP32 and 512.0 GB/s bandwidth are dominant. The Pascal part's 4.375 TFLOPS and 192.2 GB/s bandwidth are simply insufficient. The higher boost clock of the P106-100, 1709 MHz versus 1260 MHz, does not offset the 5.8 times difference in shading units.

Geekbench Vulkan follows closely at 226.8%. The RTX 3080 Ti Mobile scores 107502, while the P106-100 scores 32897. Vulkan performance tracks the compute and bandwidth advantages seen in OpenCL, with the Ampere architecture again pulling far ahead. The P106-100's lack of tensor cores and RT cores means it cannot accelerate the newer workloads that Vulkan 1.4 enables on the RTX 3080 Ti Mobile.

The average benchmark score gap is smaller than the individual test gaps. The RTX 3080 Ti Mobile averages 25740 across all its recorded benchmarks, while the P106-100 averages 23249. This 10.7% difference is tempered by the fact that the P106-100's average includes only three tests, while the RTX 3080 Ti Mobile includes ten. The RTX 3080 Ti Mobile's Passmark scores, which are not shared with the P106-100, include a G3D score of 19288 and a GPU compute score of 8471, further demonstrating its all-around capability.

The nearest rival data contextualizes each card.

The P106-100's average of 23249 is within 0.1% of the AMD Radeon Pro Vega 16 and 0.3% behind the AMD Radeon AI PRO R9700. These rival comparisons show that the RTX 3080 Ti Mobile sits in a higher performance tier, consistent with its 71st percentile ranking versus the P106-100's 68th percentile.

The wins tally is recorded as 3 for the RTX 3080 Ti Mobile and 0 for the P106-100. There are no shared tests where the P106-100 comes out ahead. This is a clean sweep, driven by architectural differences that date back to the 16 nm Pascal generation versus the 8 nm Ampere generation. The P106-100, released in 2017, predates the RTX 3080 Ti Mobile's 2022 release by nearly five years, and the data reflects that generational leap.
