The Quadro 4000M is therefore bunched with a group of mobile and older desktop parts where the spread from the lowest to the highest score is only about 2.5%. It is not an outlier in either direction.

The head-to-head result is decisive on the compute side. The AMD Radeon R7 M465 beats the NVIDIA Quadro 4000M by 630 points in Geekbench OpenCL. That is a 12.1% delta, which in practical terms means the AMD part will complete OpenCL compute tasks measurably faster. The data records one win for the AMD Radeon R7 M465 and zero wins for the NVIDIA Quadro 4000M in direct comparison.

Architecture Differences

The two GPUs come from very different eras and design philosophies. The AMD Radeon R7 M465 uses the Topaz chip built on GCN 3.0 architecture, manufactured on a 28 nm process at TSMC. The NVIDIA Quadro 4000M uses the GF104 chip on Fermi architecture, manufactured on a 40 nm process, also at TSMC. The process node difference matters: 28 nm versus 40 nm means the AMD chip is built with a smaller feature size, which generally allows for higher density and potentially better efficiency.

The transistor counts reflect that. The AMD Radeon R7 M465 packs 1,550 million transistors on a 125 mm² die, giving a transistor density of 12.4 million transistors per mm². The NVIDIA Quadro 4000M packs 1,950 million transistors on a much larger 332 mm² die, yielding a density of only 5.9 million transistors per mm². So the AMD chip is roughly half the die area of the NVIDIA chip, yet contains a substantial portion of the transistor count. That is a direct consequence of the denser 28 nm process.

The memory subsystems differ significantly. Both cards have 2 GB of GDDR5 memory, but the bus widths and resulting bandwidth are very different. The AMD Radeon R7 M465 uses a 64-bit bus with 36.00 GB/s of bandwidth. The NVIDIA Quadro 4000M uses a 256-bit bus with 80.00 GB/s of bandwidth. The NVIDIA card has more than double the memory bandwidth, which is a serious advantage in memory-bound workloads. The AMD card compensates with a higher effective memory clock: 4.5 Gbps effective versus 2.5 Gbps effective, but the narrow bus limits overall throughput.

Compute resources are split differently. The AMD Radeon R7 M465 has 384 shading units, 24 texture mapping units, and 8 raster operations pipelines. Its pixel rate is 8.192 GPixel/s and its texture rate is 24.58 GTexel/s. The NVIDIA Quadro 4000M has 336 shading units, 56 texture mapping units, and 32 ROPs. Its pixel rate is 6.650 GPixel/s and its texture rate is 26.60 GTexel/s. So the NVIDIA card has more TMUs and ROPs, giving it a higher texture rate, while the AMD card has more shaders and a higher pixel rate.

Clock speeds also diverge. The AMD Radeon R7 M465 has a base clock of 730 MHz and a boost clock of 1,024 MHz. The NVIDIA Quadro 4000M has no base or boost clock listed in the database, only a memory clock of 625 MHz. The AMD card's boost clock is high enough that its FP32 compute rating reaches 786.4 GFLOPS, and its FP16 rating is the same at 786.4 GFLOPS, indicating a 1:1 ratio. The NVIDIA Quadro 4000M has an FP32 rating of 638.4 GFLOPS and no recorded FP16 capability. In raw floating-point throughput, the AMD part is ahead.

The NVIDIA Quadro 4000M carries a 100 W TDP and uses an MXM module form factor with a 3.0 interface. It has no power connectors listed and relies on portable device dependent display outputs. The AMD Radeon R7 M465 does not have a TDP listed, but it uses a PCIe 3.0 x8 interface, which is typical of a lower-power mobile or entry-level desktop part. The AMD card supports Vulkan 1.2.170, DirectX 12 (12_0), and OpenGL 4.6. The NVIDIA card supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support recorded. That is a notable feature gap for modern compute or gaming workloads that leverage Vulkan.

The release dates underline the generational gap. The NVIDIA Quadro 4000M launched in February 2011, while the AMD Radeon R7 M465 launched in May 2016. The NVIDIA part is a Fermi-generation mobile workstation GPU; its predecessor is the Quadro FX Mobile series and its successor is the Quadro Kepler-M series. The AMD part is part of the Gem System (R7 M400) generation, with a predecessor named Solar System and a successor named Polaris Mobile. Both are marked end-of-life in the database.

The Verdict

The benchmark data points clearly to the AMD Radeon R7 M465 as the stronger compute performer. Its Geekbench OpenCL score of 5,841 beats the NVIDIA Quadro 4000M's 5,211 by 12.1%. The AMD card also holds a percentile advantage, sitting at the 33rd percentile versus the NVIDIA card's 30th percentile. For anyone running OpenCL-based workloads, the AMD part is the better choice.

The NVIDIA Quadro 4000M does have meaningful advantages in other areas. Its memory bandwidth of 80.00 GB/s is more than double the AMD card's 36.00 GB/s. It also has a wider 256-bit memory bus, which helps with large data sets and memory-intensive tasks. Its texture rate of 26.60 GTexel/s is slightly higher than the AMD card's 24.58 GTexel/s. And it carries a 100 W TDP in an MXM module format, which suggests it was designed for professional mobile workstations with more robust thermal envelopes.

However, the database records only one head-to-head benchmark, and the AMD Radeon R7 M465 wins it. The architecture gap also favors the AMD part on process technology and compute features. The 28 nm process versus 40 nm, the higher transistor density, the Vulkan support, and the 1:1 FP16 capability all point to a more modern design. The NVIDIA Quadro 4000M is a much older part, released in 2011, and its Fermi architecture lacks modern API support.

For users who prioritize raw compute throughput, the AMD Radeon R7 M465 is the stronger option. For users who need high memory bandwidth and professional mobile workstation integration, the NVIDIA Quadro 4000M has merits, but its lower compute score and older feature set weaken its case. The data favors the AMD Radeon R7 M465 overall.

It also has a higher pixel rate at 8.192 GPixel/s versus 6.650 GPixel/s. For tasks like OpenCL acceleration, general-purpose GPU compute, and any workload that relies on shader throughput, the AMD part has the edge. Its support for Vulkan 1.2.170 also makes it more suitable for modern applications that use this API. Its smaller 28 nm die and higher transistor density suggest better efficiency per unit area, which is relevant for mobile implementations.

The NVIDIA Quadro 4000M wins in memory-bound and texture-heavy scenarios. Its 80.00 GB/s bandwidth is more than double the AMD card's 36.00 GB/s, and its 256-bit bus is four times wider. This makes it better suited for workloads that stream large datasets, such as certain scientific simulations, video processing, or CAD applications that hold large textures in memory. Its texture rate of 26.60 GTexel/s is slightly higher than the AMD card's 24.58 GTexel/s, and it has 56 TMUs versus 24, which helps with complex texture filtering. Its 32 ROPs versus 8 also give it an advantage in fill-rate-heavy operations that are not purely pixel-rate bound.

The Quadro 4000M also carries a workstation pedigree in its form factor. It is an MXM module with a 100 W TDP and no power connectors, designed for professional mobile workstations. The AMD card uses a PCIe 3.0 x8 interface, which is more common in thin-and-light laptops or small desktop configurations. For users who need a drop-in professional mobile GPU with high bandwidth, the Quadro 4000M has a role. But the recorded benchmark data shows the AMD Radeon R7 M465 delivering the higher compute score, and that is the primary metric in the database. The choice depends on whether the workload is compute-bound or memory-bound. Compute favors AMD, memory bandwidth favors NVIDIA.
