NVIDIA P102-100 vs NVIDIA RTX A4500 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the NVIDIA RTX A4500 and the NVIDIA P102-100. Across the two shared benchmark tests, the RTX A4500 wins both, with the largest margin appearing in the Geekbench OpenCL test. There, the RTX A4500 scores 141837 against the P102-100's 49602, a delta of 186%. That is not a marginal advantage; it is a near-tripling of the raw compute result. The Vulkan test narrows the gap somewhat, but the RTX A4500 still leads by a substantial 92.7%, scoring 129980 versus 67454.

To put these numbers in context, the RTX A4500's average benchmark score across all recorded tests is 91671, placing it in the 93rd percentile of all GPUs in the database. Its closest rival, the NVIDIA RTX A4500 Mobile, trails by just 0.6% with an average score of 91134, while the AMD Radeon Instinct MI60 sits only 0.9% ahead at 92466. The P102-100, by contrast, averages 58528, which lands it in the 88th percentile. Its nearest rival, the AMD Radeon PRO V710, is effectively tied at 58657, a delta of -0.2%, and the AMD Radeon RX 6950 XT is 0.2% behind at 58392.

The head-to-head deltas are far larger than anything seen in either card's nearest-rival set. A 186% lead in OpenCL means the RTX A4500 delivers nearly three times the score of the P102-100 in that workload. Even the smaller Vulkan win of 92.7% is roughly double the score. The P102-100's own rival deltas are all under 1%, which shows that it sits in a tightly clustered performance band, but the RTX A4500 is in a completely different tier.

The data also reveals that the RTX A4500 has three recorded benchmarks (3DMark Steel Nomad DX12 at 3196, Geekbench OpenCL at 141837, Geekbench Vulkan at 129980), while the P102-100 has only two (Geekbench OpenCL at 49602, Geekbench Vulkan at 67454). The 3DMark result for the RTX A4500 is not directly comparable to anything in the P102-100's record set, but its presence further underscores the broader testing coverage for the newer card.

Architecture Differences

The two GPUs come from entirely different architectural generations. The RTX A4500 is built on the Ampere architecture, using the GA102 chip fabricated on an 8 nm process at Samsung. The P102-100 uses the older Pascal architecture with the GP102 chip, made on a 16 nm process at TSMC. This process gap alone explains much of the efficiency and density difference: the RTX A4500 packs 28,300 million transistors into a 628 mm² die, yielding a transistor density of 45.1M per mm². The P102-100 has 11,800 million transistors on a 471 mm² die, for a density of 25.1M per mm². The RTX A4500 crams more than twice the transistors into only a third more silicon area.

The compute resources diverge sharply. The RTX A4500 has 7168 shading units, 224 texture mapping units, and 96 ROPs. It also includes 56 ray tracing cores and 224 tensor cores, features that the P102-100 lacks entirely; both fields are marked null in the database. The P102-100 has 3200 shading units, 200 TMUs, and 80 ROPs. The shading unit count alone is a 2.24x difference in the RTX A4500's favor.

Clock speeds tell a more nuanced story. The P102-100 has a higher base clock at 1582 MHz versus 1050 MHz, and a slightly higher boost clock at 1683 MHz versus 1650 MHz. But the RTX A4500's architectural advantages more than compensate. Its FP32 throughput is 23.65 TFLOPS against the P102-100's 10.77 TFLOPS. The FP16 comparison is even more lopsided: the RTX A4500 delivers 23.65 TFLOPS at a 1:1 ratio, while the P102-100 manages only 168.3 GFLOPS at a 1:64 ratio. That is a difference of two orders of magnitude in half-precision compute, which matters for AI inference and certain scientific workloads.

Memory configurations also reflect the generational split. The RTX A4500 has 20 GB of GDDR6 on a 320-bit bus, delivering 640.0 GB/s of bandwidth. The P102-100 has 5 GB of GDDR5X on a 320-bit bus, for 440.3 GB/s. Both use the same bus width, but the RTX A4500 quadruples the capacity and adds roughly 45% more bandwidth. The memory clock difference is notable as well: the RTX A4500 runs at 2000 MHz with 16 Gbps effective, while the P102-100 runs at 1376 MHz with 11 Gbps effective.

The feature set diverges further in connectivity and outputs. The RTX A4500 offers 4x DisplayPort 1.4a outputs, while the P102-100 has no display outputs at all, a reflection of its mining-oriented design. The bus interface also differs: the RTX A4500 uses PCIe 4.0 x16, while the P102-100 is limited to PCIe 1.0 x4, a severe bottleneck for data transfer in any workload that moves data across the bus. The P102-100's generation is listed as "Mining GPUs," which explains the absence of outputs and the older, narrower bus interface.

Power profiles differ despite the performance gap. The RTX A4500 has a 200 W TDP with a single 8-pin power connector and a suggested PSU of 550 W. The P102-100 has a 250 W TDP, requires two 8-pin connectors, and suggests a 600 W PSU. The newer card delivers far more performance while drawing less power and requiring a simpler power setup.

Pixel and texture rates follow the expected pattern. The RTX A4500 reaches 158.4 GPixel/s and 369.6 GTexel/s, while the P102-100 manages 134.6 GPixel/s and 336.6 GTexel/s. The RTX A4500 leads in both, though the margin is smaller than in compute throughput, reflecting the P102-100's higher clock speeds partially offsetting its smaller core count.

API support also separates the two. The RTX A4500 supports DirectX 12 Ultimate (12_2), while the P102-100 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX A4500's DirectX 12 Ultimate designation includes features like ray tracing and variable rate shading, which the P102-100 cannot offer given its lack of RT cores.

The Verdict

The data points to a clear choice for nearly any workload. The RTX A4500 wins both head-to-head benchmarks by margins of 186% and 92.7%, has four times the memory capacity, more than double the shading units, and includes hardware ray tracing and tensor cores that the P102-100 simply does not have. Its average benchmark score of 91671 versus 58528 places it 56.6% higher overall, and its 93rd percentile ranking versus the P102-100's 88th percentile confirms that it sits in a higher performance tier.

The P102-100 does have some advantages in the recorded data. Its base clock is 532 MHz higher, its boost clock is 33 MHz higher, and it draws 50 W more power, which suggests a more aggressive power delivery design. But these clock advantages do not translate into benchmark wins. The P102-100's only redeeming quality in a direct comparison is that its nearest rivals are extremely close, with deltas under 1%, meaning it is well-matched against GPUs like the AMD Radeon PRO V710 and the AMD Radeon RX 6950 XT. The RTX A4500, by contrast, has no rival within 4.8% except the RTX A4500 Mobile, which is 0.6% behind.

For any use case that involves compute, graphics, or professional workloads, the RTX A4500 is the superior part by every benchmark metric recorded. The P102-100's lack of display outputs alone disqualifies it for any interactive or display-driven task. The RTX A4500's 20 GB memory capacity, 640.0 GB/s bandwidth, and 23.65 TFLOPS FP32 performance make it suitable for large datasets and demanding rendering workloads. The P102-100, with 5 GB memory and 10.77 TFLOPS FP32, is more limited, and its PCIe 1.0 x4 interface would bottleneck data transfers in any system that relies on host-device communication.

The production status for both is end-of-life, but the RTX A4500 was released on 2021-11-22, while the P102-100 dates to 2018-02-11. The newer architecture and later release date align with its superior performance. The RTX A4500 also has a successor listed as Workstation Ada, while the P102-100 has no successor, reflecting its niche mining origins.

Where Each One Wins

The RTX A4500 wins in every head-to-head benchmark recorded. Its advantages are most pronounced in compute-heavy workloads, as shown by the 186% OpenCL lead and the 92.7% Vulkan lead. The 20 GB memory capacity and 640.0 GB/s bandwidth make it suitable for large datasets, high-resolution textures, and machine learning inference. The presence of 56 RT cores and 224 tensor cores extends its reach into ray-traced rendering and AI acceleration, areas where the P102-100 cannot compete at all. Its 4x DisplayPort 1.4a outputs make it usable for multi-monitor professional setups, and its PCIe 4.0 x16 interface ensures fast data transfer with modern host systems. The lower 200 W TDP and single 8-pin connector also make it easier to integrate into a workstation.

The P102-100 has no benchmark wins against the RTX A4500, but the data does show areas where it is less disadvantaged. Its base clock of 1582 MHz is 532 MHz higher, and its boost clock of 1683 MHz is 33 MHz higher, which narrows the gap in pixel rate (134.6 GPixel/s versus 158.4 GPixel/s) and texture rate (336.6 GTexel/s versus 369.6 GTexel/s) relative to the compute gap. Its 250 W TDP and 2x 8-pin connectors suggest a power delivery design that favors sustained clock operation. In the context of its own nearest rivals, the P102-100 is competitive: it sits within 0.8% of the AMD Radeon PRO V710, AMD Radeon RX 6950 XT, Intel Arc A570M, and AMD Radeon RX 5600 OEM. For a system that does not require display output and can tolerate the PCIe 1.0 x4 interface, the P102-100 could serve in compute-only roles where its higher clocks help, but the RTX A4500 remains the stronger choice in every recorded benchmark metric.
