AMD Radeon R7 M465 vs NVIDIA Quadro P2000 Comparison

The NVIDIA Quadro P2000 and AMD Radeon R7 M465 occupy very different positions in the hardware landscape, as the data shows a decisive performance gap between the two. The Quadro P2000, built on the Pascal architecture, is a professional workstation card, while the Radeon R7 M465 is a mobile graphics solution based on the older GCN 3.0 architecture. Benchmark results indicate that the Quadro P2000 is in a completely different performance class, with the only shared benchmark showing a massive 244.5% advantage for the NVIDIA product.

Head-to-Head Benchmarks

The single directly comparable benchmark between these two GPUs is the Geekbench OpenCL test, and the results are not close. The NVIDIA Quadro P2000 scores 20,125 points, while the AMD Radeon R7 M465 manages only 5,841 points. This represents a delta of 244.5%, meaning the Quadro P2000 delivers more than three times the compute performance in this workload. The magnitude of this difference is so large that it suggests the two products are not intended for the same tasks or market segments.

Looking at the broader benchmark landscape, the Quadro P2000 also has a much richer set of test results. It has been evaluated across nine different benchmarks, including Passmark DirectX 9, 10, 11, and 12 tests, as well as G2D, G3D, and GPU compute tests. The Radeon R7 M465 has only one recorded benchmark result, the Geekbench OpenCL score. This disparity in available data points itself is informative — the Quadro P2000 has been tested across a wide range of DirectX versions, while the R7 M465 lacks any recorded DirectX or Passmark results in the fact pack.

The average benchmark score tells a similar story. The Quadro P2000 has an average score of 6,049 across its benchmark suite, while the R7 M465's average is 5,841, which is identical to its single Geekbench score. However, this average comparison is somewhat misleading because the Quadro P2000's average includes several much lower Passmark scores, such as 28 in DirectX 12 and 34 in DirectX 10, which pull down its average. The Geekbench OpenCL score of 20,125 is the standout result for the NVIDIA card, showing its compute capability is far ahead of what the R7 M465 can offer.

Where Each One Wins

The NVIDIA Quadro P2000 wins the only head-to-head benchmark by a substantial margin, and it also dominates in terms of benchmark coverage. The data shows the Quadro P2000 has a win count of 1 in direct comparisons, while the R7 M465 has 0 wins. This means the Quadro P2000 is the clear winner in every measurable category where both products have data.

For compute-heavy workloads, the Quadro P2000 is the obvious choice. Its Geekbench OpenCL score of 20,125 versus 5,841 for the R7 M465 indicates a massive advantage in general-purpose GPU computing. The Quadro P2000 also achieves a Passmark GPU Compute score of 2,933, which is not directly comparable to the R7 M465 since no such data exists for the AMD part. The R7 M465, by contrast, has no recorded wins in any benchmark category.

In terms of legacy DirectX support, the Quadro P2000 shows varying performance across different versions. It scores 124 in Passmark DirectX 9, 34 in DirectX 10, 47 in DirectX 11, and 28 in DirectX 12. This pattern suggests the Quadro P2000 performs better in older DirectX workloads, which is typical for a professional card that may be used with legacy applications. The R7 M465 has no comparable data, so it cannot be evaluated for legacy DirectX performance from the fact pack.

Architecture Differences

The architectural gap between these two GPUs is substantial. The NVIDIA Quadro P2000 uses the GP106 chip on the Pascal architecture, fabricated on a 16 nm process at TSMC. It contains 4,400 million transistors on a 200 mm² die, giving it a transistor density of 22.0 million per mm². The AMD Radeon R7 M465 uses the Topaz chip on the GCN 3.0 architecture, also fabricated at TSMC but on a larger 28 nm process. It contains 1,550 million transistors on a 125 mm² die, with a transistor density of 12.4 million per mm².

These architectural differences translate directly into compute resources. The Quadro P2000 has 1,024 shading units, 64 texture mapping units, and 40 render output units. The R7 M465 has only 384 shading units, 24 TMUs, and 8 ROPs. This means the Quadro P2000 has approximately 2.7 times the shading units, 2.7 times the TMUs, and 5 times the ROPs of the AMD part. The pixel rate of the Quadro P2000 is 59.20 GPixel/s versus 8.192 GPixel/s for the R7 M465, and the texture rate is 94.72 GTexel/s versus 24.58 GTexel/s.

Clock speeds also differ significantly. The Quadro P2000 has a base clock of 1076 MHz and a boost clock of 1480 MHz, while the R7 M465 has a base clock of 730 MHz and a boost clock of 1024 MHz. This clock advantage, combined with the larger shader count, gives the Quadro P2000 a floating-point performance of 3.031 TFLOPS in FP32, compared to 786.4 GFLOPS for the R7 M465. The FP16 performance is also divergent: the Quadro P2000 achieves 47.36 GFLOPS at a 1:64 ratio, while the R7 M465 achieves 786.4 GFLOPS at a 1:1 ratio, meaning the AMD card has full-rate FP16 while the NVIDIA card is heavily reduced.

Memory configuration further separates the two. The Quadro P2000 has 5 GB of GDDR5 memory on a 160-bit bus, delivering 140.2 GB/s of bandwidth. The R7 M465 has only 2 GB of GDDR5 on a 64-bit bus, giving it 36.00 GB/s of bandwidth. The memory clock is also different, with the Quadro P2000 running at 1752 MHz (7 Gbps effective) versus 1125 MHz (4.5 Gbps effective) for the R7 M465.

The specification table reinforces the benchmark results. The Quadro P2000 is a fundamentally more capable GPU in almost every measurable aspect, from raw compute resources to memory bandwidth and API support. The only area where the R7 M465 shows an advantage is in FP16 performance ratio, where it operates at a 1:1 rate compared to the Quadro P2000's 1:64 ratio, but this is a narrow technical detail that does not overcome the overall performance gulf.
