AMD Radeon R7 M465 vs NVIDIA Quadro 4000 Comparison

The Verdict

The benchmark database presents a clear, though narrow, picture for these two end-of-life mobile and workstation graphics solutions. The AMD Radeon R7 M465 is the outright winner in the single recorded compute benchmark, outperforming the NVIDIA Quadro 4000 by a significant margin. The data shows a 14.8% delta in favor of the AMD part, with the R7 M465 scoring 5841 points in Geekbench OpenCL versus the Quadro 4000's 4979 points.

For users seeking raw compute throughput in OpenCL workloads, the AMD Radeon R7 M465 is the definitive choice from this dataset. It also holds a higher overall percentile rank among all GPUs, sitting at the 33rd percentile compared to the Quadro 4000's 29th percentile. The Quadro 4000, however, remains relevant for legacy professional applications that rely on its specific feature set and driver ecosystem, even if its raw compute score is lower. The choice hinges on whether the user prioritizes the higher compute score of the AMD part or the established professional workstation pedigree of the NVIDIA part, which the data suggests through its architecture and memory configuration.

Where Each One Wins

The recorded benchmark data gives the AMD Radeon R7 M465 a single, decisive victory in Geekbench OpenCL. This is the only head-to-head test in the database, and it shows the AMD card leading by 862 points. The AMD part's win is substantial, and its nearest rivals in the database, such as the AMD Radeon R5 M435 with a score of 5859, are only 0.3% ahead, indicating the R7 M465 is competitive within its immediate performance tier.

The NVIDIA Quadro 4000, while losing the compute test, does not have a benchmark win in the database. However, its strengths lie in architectural features that are not captured by a raw compute score. The Quadro 4000 features a 256-bit memory bus, which provides a bandwidth of 89.86 GB/s, more than double the 36.00 GB/s of the AMD card. This suggests the NVIDIA part would be superior in memory-bandwidth-intensive tasks, such as large texture fetches or certain professional visualization workloads, even though the recorded compute benchmark does not reflect this advantage.

The AMD Radeon R7 M465 also demonstrates a clear win in transistor density and process efficiency, being built on a 28 nm node compared to the Quadro's 40 nm node. This is a generational advantage, as the AMD part achieves a higher transistor density of 12.4 million per square millimeter versus 5.9 million for the NVIDIA part. For users focused purely on the compute performance metric, the AMD card is the winner; for those concerned with memory throughput and legacy workstation features, the NVIDIA card has unquantified but implied advantages.

Architecture Differences

The two GPUs come from different architectural eras and design philosophies. The NVIDIA Quadro 4000 is built on the Fermi architecture, using the GF100 chip, and was released in November 2010. It is manufactured on a 40 nm process at TSMC and packs 3,100 million transistors into a large 529 mm² die. The AMD Radeon R7 M465, by contrast, uses the GCN 3.0 architecture with the Topaz chip, released in May 2016. It is built on a more modern 28 nm process, also at TSMC, but contains only 1,550 million transistors on a much smaller 125 mm² die.

The compute configurations differ notably. The Quadro 4000 has 256 shading units, 32 texture mapping units (TMUs), and 32 raster output units (ROPs). The Radeon R7 M465 has more shading units at 384, but fewer TMUs at 24 and significantly fewer ROPs at 8. Despite having fewer ROPs, the AMD card achieves a higher pixel rate of 8.192 GPixel/s compared to 7.600 GPixel/s for the NVIDIA card, due to its higher clock speeds. The AMD card also has a higher texture rate of 24.58 GTexel/s versus 15.20 GTexel/s.

Memory architecture is a major differentiator. The Quadro 4000 uses a 256-bit bus with 2 GB of GDDR5 memory, yielding 89.86 GB/s of bandwidth. The R7 M465 also has 2 GB of GDDR5 memory but on a 64-bit bus, resulting in only 36.00 GB/s. The NVIDIA card runs its memory at 702 MHz (2.8 Gbps effective), while the AMD card runs at 1125 MHz (4.5 Gbps effective). The clock speeds for the GPU cores also differ: the Quadro 4000 has no listed base or boost clock in the database, while the R7 M465 has a base clock of 730 MHz and a boost clock of 1024 MHz.

API support also separates them. The Quadro 4000 supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support listed. The Radeon R7 M465 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The AMD card also supports FP16 computation at a 1:1 ratio, delivering 786.4 GFLOPS for both FP16 and FP32. The NVIDIA card only lists FP32 performance at 486.4 GFLOPS, with no FP16 support noted. The bus interface also differs, with the NVIDIA card using PCIe 2.0 x16 and the AMD card using PCIe 3.0 x8.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL, and it is a decisive win for the AMD Radeon R7 M465. The AMD card scores 5841, while the NVIDIA Quadro 4000 scores 4979. The delta is 14.8% in favor of the AMD card. This is a substantial margin in synthetic compute workloads, and it aligns with the AMD card's higher shading unit count and much higher clock speeds.

The Quadro 4000's nearest rivals in the database include the NVIDIA GeForce RTX 5060 Ti 16 GB with a score of 4970, which is only 0.2% behind the Quadro. This indicates the Quadro 4000 is tightly clustered with a modern mainstream GPU in this specific compute test. The AMD Radeon R7 M465, by comparison, sits near the AMD Radeon R5 M435 with a score of 5859, just 0.3% ahead of the R7 M465. The Intel UHD Graphics 730 scores 5929, which is 1.5% ahead of the AMD card.

Looking at the compute score differences, the AMD card's 786.4 GFLOPS FP32 output is 61.7% higher than the NVIDIA card's 486.4 GFLOPS. This raw compute advantage directly translates to the OpenCL benchmark result. However, the NVIDIA card's memory bandwidth advantage (89.86 GB/s versus 36.00 GB/s) suggests that in memory-bound scenarios, the Quadro 4000 could close the gap or even overtake the AMD card, though this is not reflected in the single recorded test.

The texture rate also favors the AMD card at 24.58 GTexel/s versus 15.20 GTexel/s, a 61.7% advantage. The pixel rate difference is smaller, with the AMD card at 8.192 GPixel/s versus 7.600 GPixel/s, an 7.8% advantage. These numbers collectively indicate that the AMD Radeon R7 M465 is the more capable compute and texture processing part, while the NVIDIA Quadro 4000 holds a clear lead in memory throughput.
