GPU Comparison

The NVIDIA Quadro P2000 is the clear winner in this comparison, delivering a Geekbench OpenCL score of 20,125 compared to the AMD Radeon HD 7730M's 6,581. This represents a 67.3% deficit for the AMD part, a massive performance gap that defines the entire head-to-head analysis. The data shows that the Quadro P2000 is not just faster but in a completely different performance tier, with benchmark results indicating a dominant victory across the board.

Head-to-Head Benchmarks

The only directly comparable benchmark in the data is Geekbench OpenCL, and the results are decisive. The NVIDIA Quadro P2000 scores 20,125 points, while the AMD Radeon HD 7730M manages only 6,581 points. This yields a deltaPct of -67.3% for the AMD part, meaning it delivers less than one-third of the Quadro's compute performance in this workload. This is not a marginal difference; it is a generational chasm.

Looking at the context of the Quadro P2000's other benchmark results reinforces its superiority. In Passmark tests, the Quadro P2000 scores 6,956 in G3D and 2,933 in GPU compute, with additional scores of 626 in G2D, 124 in DirectX 9, 47 in DirectX 11, 34 in DirectX 10, and 28 in DirectX 12. These figures show a professional-grade card with consistent performance across legacy and modern APIs. The Radeon HD 7730M, by contrast, has only a single benchmark score to its name, making it impossible to evaluate its performance in these other categories.

The average benchmark score tells a similar story, though with a twist. The Quadro P2000's average is 6,049, while the Radeon HD 7730M's average is 6,581. This is because the Quadro's average is dragged down by its low Passmark DirectX scores, which are legacy API tests where the card does not excel. However, the Geekbench OpenCL score of 20,125 is the more representative measure of raw compute capability, and there the Quadro P2000 wins outright. The Radeon HD 7730M's percentile rank among all GPUs is 38, while the Quadro P2000 sits at 35, but this ranking is based on average scores that include the Passmark legacy tests.

In terms of nearest rivals, the Radeon HD 7730M sits in a cluster of older and lower-end parts. Its nearest rival is the AMD Radeon R7 M460, which scores 6,612, a deltaPct of -0.5% relative to the HD 7730M. The Intel UHD Graphics P750 scores 6,554, just 0.4% behind. The NVIDIA GeForce GTX 670M scores 6,513, 1% behind, and the NVIDIA GeForce GT 555M scores 6,493, 1.4% behind. These are all extremely close results, indicating the HD 7730M is squarely in the entry-level mobile graphics territory.

The Quadro P2000's nearest rivals are a step up. The NVIDIA GeForce MX230 scores 6,077, which is 0.5% behind the Quadro. The NVIDIA RTX A400 scores 6,078, also 0.5% behind. The AMD Radeon 760M scores 6,019, 0.5% ahead of the Quadro, and the AMD Radeon RX 6400 scores 6,001, 0.8% ahead. These deltas are small, but they indicate the Quadro P2000 is competitive with modern entry-level and integrated graphics, despite its age.

The Quadro's clock advantage is substantial, with a boost clock more than double that of the AMD part. Memory clocks differ as well, with the Radeon using 900 MHz (1,800 Mbps effective) and the Quadro using 1,752 MHz (7 Gbps effective).

In terms of compute resources, the Quadro P2000 has exactly double the shading units of the Radeon HD 7730M: 1,024 versus 512. It also has double the texture mapping units (64 versus 32) and more than double the render output units (40 versus 16). The Quadro's pixel rate is 59.20 GPixel/s compared to the Radeon's 10.80 GPixel/s, and its texture rate is 94.72 GTexel/s versus 21.60 GTexel/s. The FP32 performance is the starkest difference: the Quadro delivers 3.031 TFLOPS against the Radeon's 691.2 GFLOPS.

The memory subsystems are also vastly different. The Radeon HD 7730M uses 2 GB of DDR3 on a 128-bit bus, providing 28.80 GB/s of bandwidth. The Quadro P2000 uses 5 GB of GDDR5 on a 160-bit bus, delivering 140.2 GB/s. The Quadro has nearly five times the bandwidth, which is critical for compute workloads.
