AMD Radeon RX 7900M vs NVIDIA P102-100 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive advantage for the AMD Radeon RX 7900M across every shared benchmark. In the Geekbench OpenCL test, the RX 7900M scores 129,499 against the NVIDIA P102-100's 49,602, a delta of 161.1%. That is not a narrow margin; it is a complete tier separation. The Vulkan result tells a similar story, with the RX 7900M posting 158,760 versus the P102-100's 67,454, a 135.4% advantage. In both compute-oriented workloads, the AMD part more than doubles the output of the NVIDIA part.

Context from the database's nearest rival comparisons reinforces how far apart these two are. The RX 7900M sits at the 94th percentile among all GPUs, with an average benchmark score of 97,487. Its closest rivals include the AMD Radeon Pro VII at 97,131 (0.4% behind), the NVIDIA Quadro RTX 6000 at 101,872 (4.3% ahead), the AMD Radeon Instinct MI60 at 92,466 (5.4% behind), and the NVIDIA RTX A4500 at 91,671 (6.3% behind). The P102-100, by contrast, sits at the 88th percentile with an average score of 58,528. Its nearest rivals are much closer in performance: the AMD Radeon PRO V710 at 58,657 (0.2% ahead), the AMD Radeon RX 6950 XT at 58,392 (0.2% behind), the Intel Arc A570M at 58,239 (0.5% behind), and the AMD Radeon RX 5600 OEM at 58,085 (0.8% behind). The P102-100 is clustered with mid-range parts, while the RX 7900M is operating in a different performance bracket entirely.

The head-to-head delta of 161.1% in OpenCL is worth pausing on. The RX 7900M's raw FP32 throughput is listed at 38.52 TFLOPS, whereas the P102-100 manages 10.77 TFLOPS. That is a 3.6x gap in theoretical compute, which explains why the OpenCL score difference is so large. The Vulkan delta of 135.4% is slightly smaller, but still overwhelming. The P102-100's FP16 output is listed at 168.3 GFLOPS (1:64), a figure that is effectively negligible for modern compute workloads, while the RX 7900M offers 77.05 TFLOPS FP16 (2:1). For any workload that leverages half-precision, the AMD part is in a different universe.

The wins tally reflects this: the RX 7900M wins 2 out of 2 head-to-head benchmarks, while the P102-100 wins none. There is no metric in the shared test set where the NVIDIA card comes out ahead. Even the P102-100's closest rival comparisons show it is only marginally faster than an RX 6950 XT (0.2%), which itself is far below the RX 7900M's average score. The data does not suggest a close contest; it suggests a generational and architectural chasm.

The Verdict

For any user selecting between these two based strictly on the database metrics, the choice is unambiguous: the AMD Radeon RX 7900M delivers dramatically higher scores in both OpenCL and Vulkan, with deltas of 161.1% and 135.4% respectively. The RX 7900M also ranks higher overall, at the 94th percentile versus the P102-100's 88th. Its average benchmark score of 97,487 is 66.6% higher than the P102-100's 58,528. That is not a marginal improvement; it is a different class of hardware.

The P102-100 is listed as an end-of-life product belonging to the Mining GPUs generation, released in early 2018, whereas the RX 4 7900M is part of the Radeon RX 7900 series, released in October 2023, and is still marked as active production status. The P102-100 has no display outputs, meaning it cannot drive a monitor; the RX 100-100 has outputs described as portable device dependent, meaning it is designed for mobile integration. The P102-100 also uses a PCIe 1.0 x4 interface, while the RX 7900M uses PCIe 4.0 x16. For compute-only or mining applications, the P102-100 might be usable in legacy systems, but the data shows its performance is not competitive with the RX 7900M in any measured test.

The verdict from the data is simple: choose the RX 7900M for any workload that appears in the benchmark database's test suite, which includes OpenCL and Vulkan compute. The P102-100 should only be considered if the user has a specific legacy requirement for a GPU with no display outputs and a 250W TDP, a dual-slot form factor, and 2x 8-pin power connectors. But the performance data offers no reason to prefer it.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The AMD Radeon RX 7900M uses RDNA 3.0 architecture on the Navi 31 chip, with the codename Plum Bonito, and belongs to the Navi Mobile (RX 7000M) generation. The NVIDIA P102-100 uses the Pascal architecture on the GP102 chip, and belongs to the Mining GPUs generation. These are separated by several product generations, which explains the performance gap.

The process node tells the story clearly: the RX 7900M is fabricated on a 5 nm process at TSMC, while the P102-100 uses a 16 nm process, also at TSMC. The transistor counts reflect this: the RX 7900M packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The P102-100 has 11,800 million transistors on a 471 mm² die, with a density of 25.1M per mm². The density difference is nearly 4.4x, showing how much more tightly packed the newer node is.

The memory architectures also differ substantially. The RX 7900M uses 16 GB of GDDR6 on a 256-bit bus, with memory clocked at 2250 MHz (18 Gbps effective), producing 576.0 GB/s of bandwidth. The P102-100 uses 5 GB of GDDR5X on a 320-bit bus, with memory at 1376 MHz (11 Gbps effective), yielding 440.3 GB/s. The RX 7900M has more capacity and higher bandwidth, despite a narrower bus, thanks to the faster memory technology.

Compute resources diverge sharply. The RX 7900M has 4608 shading units, 288 texture mapping units, 192 raster operation units, and 72 ray tracing cores. It has no tensor cores listed. The P102-100 has 3200 shading units, 200 TMUs, and 80 ROPs, with no ray tracing cores and no tensor cores. The RX 7900M's pixel rate is 401.3 GPixel/s versus 134.6 GPixel/s for the P102-100, and its texture rate is 601.9 GTexel/s versus 336.6 GTexel/s. The FP32 throughput of 38.52 TFLOPS versus 10.77 TFLOPS and FP16 of 77.05 TFLOPS versus 168.3 GFLOPS shows the architectural efficiency gain is massive.

The TDP also differs: the RX 7900M draws 180 W, while the P102-100 draws 250 W. The RX 7900M achieves far higher performance at a lower power envelope. The P102-100 requires a 600 W suggested PSU and two 8-pin power connectors, while the RX 7900M is an IGP (integrated graphics processor) with no power connectors listed.

Specification Differences

The two cards differ in nearly every specification field. The RX 7900M has 16 GB of GDDR6 memory; the P102-100 has 5 GB of GDDR5X. The memory bus is 256-bit versus 320-bit, but the effective bandwidth is 576.0 GB/s versus 440.3 GB/s. The base clock is 1825 MHz versus 1582 MHz, and the boost clock is 2090 MHz versus 1683 MHz.

Shading units: 4608 versus 3200. TMUs: 288 versus 200. ROPs: 192 versus 80. The RX 7900M has 72 ray tracing cores; the P102-100 has none. The RX 7900M is on a 5 nm process; the P102-100 is on 16 nm.

It wins in every category that matters for compute performance.

The NVIDIA P102-100 wins no shared benchmarks. Its nearest rival data shows it is competitive with mid-range cards like the AMD Radeon RX 6950 XT (0.2% faster) and the Intel Arc A570M (0.5% faster), but that entire cluster is far below the RX 7900M's performance tier. The P102-100 does have a wider memory bus at 320-bit versus 256-bit, but the RX 7900M's faster memory technology overcomes that. The P102-100 has a lower transistor count and lower density, and its only advantage fields are its dual-slot form factor and its explicit 267 mm length, which are not performance metrics. The P102-100's bus interface is PCIe 1.0 x4, which is a severe bottleneck for modern workloads, whereas the RX 7900M uses PCIe 4.0 x16.

For use cases involving OpenCL compute, Vulkan rendering, ray tracing, or any modern API workload, the RX 7900M is the clear winner. The P102-100 might be relevant for legacy mining applications, given its mining-oriented generation and lack of display outputs, but the benchmark data does not support any performance advantage. The RX 7900M is also the only one of the two with an active production status, making it the more future-proof choice. The P102-100 is end-of-life, which means it is no longer produced or supported. In every measurable way, the AMD Radeon RX 7900M is the superior GPU.
