AMD Radeon R7 M340 vs NVIDIA Quadro 4000 Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison available between the AMD Radeon R7 M340 and the NVIDIA Quadro 4000 is the Geekbench OpenCL test. In this single head-to-head matchup, the NVIDIA Quadro 4000 emerges victorious with a score of 4979, while the AMD Radeon R7 M340 trails at 4932. The performance delta is a narrow 0.9% in favor of the NVIDIA card. This is a remarkably close result, indicating that neither GPU holds a decisive computational advantage in OpenCL workloads when measured by this specific benchmark.

Looking at the broader benchmark landscape, the AMD Radeon R7 M340 achieves an average benchmark score of 5063, which places it in the 30th percentile of all GPUs. The NVIDIA Quadro 4000, by contrast, has an average benchmark score of 4979, placing it in the 29th percentile. The difference in average scores is approximately 1.7%, with the AMD part holding a slight edge in aggregate performance across multiple tests, even though it lost the single direct head-to-head OpenCL test. This suggests that the R7 M340 may perform relatively better in other workloads not covered by the head-to-head comparison.

The nearest rival data provides additional context. The AMD Radeon R7 M340's closest competitor is the AMD Radeon R7 240, which shares the exact same average score of 5063, representing a 0% delta. The AMD FirePro W4170M follows closely at 5034 (0.6% behind), the AMD Radeon R5 M430 at 5018 (0.9% behind), and the AMD Radeon R7 Graphics at 4998 (1.3% behind). For the NVIDIA Quadro 4000, the nearest rival is the AMD Radeon R7 M360 at 4931, which trails by 1%. Interestingly, the NVIDIA GeForce RTX 5060 Ti 16 GB scores 4970, placing it 0.2% behind the Quadro 4000, while the AMD Radeon R7 Graphics (4998) and AMD Radeon R5 M430 (5018) sit 0.4% and 0.8% ahead, respectively. These figures illustrate that both cards occupy a similar performance tier, with the AMD card marginally ahead in average terms but the NVIDIA card winning the direct comparison.

Architecture Differences

The architectural divide between these two GPUs is substantial, reflecting their different design philosophies and release periods. The AMD Radeon R7 M340 is built on the GCN 3.0 architecture, utilizing the Meso chip manufactured on a 28 nm process at TSMC. The NVIDIA Quadro 4000 employs the Fermi architecture with the GF100 chip, also fabricated by TSMC but on a larger 40 nm process node. The process node difference is significant: the 28 nm node allows for a smaller die and higher transistor density compared to the older 40 nm node.

Transistor counts reveal a striking inversion. The NVIDIA Quadro 4000 contains 3,100 million transistors on a 529 mm² die, yielding a transistor density of 5.9 million per square millimeter. The AMD Radeon R7 M340, despite having fewer total transistors at 1,550 million, achieves a much higher density of 12.4 million per square millimeter on a die size of just 125 mm². This density advantage is a direct consequence of the more advanced manufacturing process, allowing AMD to pack nearly twice as many transistors per unit area.

The memory subsystems differ fundamentally. The AMD Radeon R7 M340 features 2 GB of DDR3 memory on a 64-bit bus, delivering 16.00 GB/s of bandwidth. The NVIDIA Quadro 4000 also has 2 GB of memory, but it uses GDDR5 on a 256-bit bus, providing 89.86 GB/s of bandwidth. This represents a 5.6x bandwidth advantage for the NVIDIA card, which could matter in memory-intensive workloads. Memory clocks differ as well: the AMD card runs at 1000 MHz (2 Gbps effective), while the NVIDIA card runs at 702 MHz (2.8 Gbps effective).

Compute unit configurations also diverge. The AMD Radeon R7 M340 has 320 shading units, 20 texture mapping units, and 8 raster output units. The NVIDIA Quadro 4000 has 256 shading units, 32 TMUs, and 32 ROPs. Despite having fewer shading units, the NVIDIA card has more TMUs and ROPs. The AMD card achieves a pixel rate of 8.168 GPixel/s and a texture rate of 20.42 GTexel/s, while the NVIDIA card delivers 7.600 GPixel/s and 15.20 GTexel/s, respectively. In FP32 compute, the AMD card reaches 653.4 GFLOPS, while the NVIDIA card reaches 486.4 GFLOPS. The AMD card also supports FP16 at 653.4 GFLOPS (1:1 ratio), whereas the NVIDIA card has no listed FP16 capability.

API support differs as well. The AMD Radeon R7 M340 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The NVIDIA Quadro 4000 supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support listed. The bus interfaces also differ: the AMD card uses PCIe 3.0 x8, while the NVIDIA card uses PCIe 2.0 x16. Power characteristics are only specified for the NVIDIA card, which has a TDP of 142 W, requires a 1x 6-pin power connector, and suggests a 300 W PSU. The NVIDIA card is single-slot with dimensions of 241 mm length, 111 mm height, and 20 mm width, with display outputs of 1x DVI and 2x DisplayPort.

Where Each One Wins

The AMD Radeon R7 M340 wins in several key compute-oriented metrics. It delivers higher raw FP32 performance at 653.4 GFLOPS compared to the NVIDIA Quadro 4000's 486.4 GFLOPS, a 34% advantage. The AMD card also has superior pixel rate (8.168 GPixel/s vs 7.600 GPixel/s) and texture rate (20.42 GTexel/s vs 15.20 GTexel/s). Its higher shading unit count (320 vs 256) and support for FP16 computation give it flexibility in modern compute workloads. The AMD card's 28 nm process node provides better transistor density, and its support for Vulkan 1.2.170 and DirectX 12 (12_0) makes it more compatible with contemporary graphics APIs. Its average benchmark score of 5063 also exceeds the NVIDIA card's 4979, and it sits in a higher percentile ranking.

The NVIDIA Quadro 4000 counters with a commanding memory bandwidth advantage of 89.86 GB/s versus 16.00 GB/s, a 5.6x difference that benefits memory-heavy tasks. It has more TMUs (32 vs 20) and significantly more ROPs (32 vs 8), which can improve fill-rate-bound rendering scenarios. The NVIDIA card supports PCIe 2.0 x16, which offers a wider bus interface than the AMD card's PCIe 3.0 x8. It also has defined physical specifications, including single-slot cooling and a 142 W TDP, making it easier to integrate in professional workstation environments with known power and space requirements. The NVIDIA card won the only direct head-to-head benchmark, the Geekbench OpenCL test, by 0.9%.

The Verdict

Based strictly on the data provided, the choice between these two end-of-life GPUs depends on the specific workload priorities. The AMD Radeon R7 M340 is the better pick for general compute performance, as indicated by its higher average benchmark score (5063 vs 4979), higher FP32 throughput (653.4 GFLOPS vs 486.4 GFLOPS), and superior pixel and texture rates. Its more modern 28 nm process, support for Vulkan, and DirectX 12 (12_0) feature level make it the more future-proof option for software leveraging contemporary APIs. Users running applications that favor raw shader compute or FP16 operations would benefit from the AMD card.

The NVIDIA Quadro 4000, despite being older and built on the 40 nm Fermi architecture, holds the advantage in memory bandwidth-critical scenarios. Its 89.86 GB/s of bandwidth, delivered via a 256-bit GDDR5 interface, dwarfs the AMD card's 16.00 GB/s. For workloads that are bandwidth-bound—such as certain rendering tasks, large texture streaming, or data-intensive compute—the NVIDIA card's memory subsystem provides a decisive edge. Its higher ROP count (32 vs 8) also makes it more suitable for fill-rate-limited operations, and its defined single-slot form factor with a 142 W TDP offers predictable integration in workstations. The NVIDIA card's win in the direct OpenCL head-to-head (4979 vs 4932) further demonstrates its competitiveness in that specific test.

The data presents a trade-off: the AMD Radeon R7 M340 offers superior compute density and modern API support, while the NVIDIA Quadro 4000 offers vastly superior memory bandwidth and a more established professional form factor. Neither card dominates decisively, as their average scores differ by only 1.7% and their head-to-head delta is just 0.9%. Users prioritizing compute throughput and contemporary features should select the AMD Radeon R7 M340; users prioritizing memory bandwidth and predictable workstation integration should select the NVIDIA Quadro 4000.
