AMD Radeon R7 M465 vs NVIDIA RTX A400 Comparison

The NVIDIA RTX A400 and AMD Radeon R7 M465 occupy vastly different tiers of the GPU landscape, separated by nearly a decade of architectural progress. The data shows a decisive performance gulf, but the comparison is still instructive for understanding where each part fits in the broader market. The RTX A400 is an active, modern workstation solution, while the R7 M465 is an end-of-life mobile chip from 2016.

Head-to-Head Benchmarks

The only direct benchmark comparison available is the Geekbench OpenCL test, and the results are stark. The NVIDIA RTX A400 scores 22,844, while the AMD Radeon R7 M465 manages only 5,841. This translates to a 291.1% advantage for the RTX A400, meaning it delivers nearly four times the compute performance of the older AMD part in this specific workload. This is not a marginal victory; it is a generational obliteration that reflects the fundamental differences in their design philosophies and target markets.

Looking at the broader benchmark suite for the RTX A400, its strengths become even clearer. In Vulkan, it posts a score of 22,237, which is nearly identical to its OpenCL result, indicating strong cross-API consistency. The legacy DirectX tests tell a more nuanced story: the card scores 87 in DirectX 9, 37 in DirectX 11, 32 in DirectX 10, and just 27 in DirectX 12. These low absolute numbers are typical for a professional card, as they are not optimized for gaming APIs, but the relative performance still shows a clear hierarchy. The R7 M465 has no comparable data in these tests, so a direct comparison is impossible. However, the RTX A400’s Passmark G3D score of 5,983 and its compute score of 2,557 provide a more complete picture of its capabilities beyond the single Geekbench result.

The RTX A400’s average benchmark score of 6,078 places it in the 35th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce MX230 (average score 6,077, a 0% delta), the NVIDIA Quadro P2000 (6,049, +0.5% faster), and the AMD Radeon 760M (6,019, +1% faster). This tells us that while the RTX A400 is a clear winner against the R7 M465, it is not a high-flying performer in the absolute sense; it sits in a competitive mid-low tier where small percentage differences separate it from similar products. The R7 M465, with its average score of 5,841, sits in the 33rd percentile, just two points behind the RTX A400’s percentile ranking, but its nearest rivals are much slower, including the AMD Radeon R5 M435 (5,859, -0.3% slower) and the NVIDIA GeForce GTX 550 Ti (5,731, +1.9% faster for the R7). This shows the R7 M465 is at the very bottom of the performance spectrum, even compared to other legacy parts.

The Verdict

From the data, there is no scenario where the AMD Radeon R7 M465 is the recommended choice for any modern workload. The RTX A400 is 291.1% faster in OpenCL, and it offers a suite of modern features and APIs that the R7 M465 simply lacks. The R7 M465’s sole benchmark score of 5,841 in OpenCL is its only data point, and it is thoroughly eclipsed by the RTX A400’s score of 22,844 in the same test.

The RTX A400 is the clear pick for anyone needing a low-profile, single-slot, active workstation card with modern driver support. Its 4 GB of GDDR6 memory, RT cores, and Tensor cores provide capabilities that the R7 M465 cannot match. The R7 M465 is an end-of-life product with no production status, making it obsolete for new builds. The data suggests that the R7 M465 should only be considered for legacy system repairs or for applications where its specific, limited feature set is a hard requirement. The RTX A400 is a forward-looking product; the R7 M465 is a relic. The verdict is unambiguous: the RTX A400 is the superior part in every measurable way.

Architecture Differences

The architectural chasm between these two GPUs is vast. The NVIDIA RTX A400 is built on the Ampere architecture using an 8 nm process at Samsung. It packs 8,700 million transistors into a 200 mm² die, achieving a transistor density of 43.5 million per square millimeter. In contrast, the AMD Radeon R7 M465 uses the older GCN 3.0 architecture on a 28 nm process from TSMC. It contains just 1,550 million transistors on a 125 mm² die, with a density of 12.4 million per square millimeter. This difference in manufacturing technology alone explains a massive portion of the performance gap, as the RTX A400 can fit far more transistors in a smaller area.

The compute resources are equally disparate. The RTX A400 features 768 shading units, 24 TMUs, and 16 ROPs, while the R7 M465 has 384 shading units, 24 TMUs, and only 8 ROPs. This gives the RTX A400 double the shading units and double the ROPs. Clock speeds also favor the newer card: the RTX A400 has a base clock of 1417 MHz and a boost clock of 1762 MHz, while the R7 M465 operates at a base of 730 MHz and boosts to 1024 MHz. The resultant fill rates are telling: the RTX A400 achieves a pixel rate of 28.19 GPixel/s and a texture rate of 42.29 GTexel/s, compared to the R7 M465’s 8.192 GPixel/s and 24.58 GTexel/s.

Memory is another major differentiator. The RTX A400 uses 4 GB of GDDR6 on a 64-bit bus, delivering 96.00 GB/s of bandwidth. The R7 M465 has 2 GB of GDDR5 on the same 64-bit bus, but its bandwidth is only 36.00 GB/s. Furthermore, the RTX A400 introduces dedicated hardware that the R7 M465 lacks entirely: 6 RT cores and 24 Tensor cores. This enables hardware-accelerated ray tracing and AI workloads, features that are completely absent on the GCN 3.0 part. The RTX A400 also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the R7 M465 is limited to DirectX 12 (12_0) and Vulkan 1.2.170. Finally, the RTX A400 uses a PCIe 4.0 x8 interface, double the bandwidth of the R7 M465’s PCIe 3.0 x8 connection.

Where Each One Wins

The NVIDIA RTX A400 wins in every category where data exists. Its 291.1% lead in OpenCL compute makes it the obvious choice for general-purpose GPU compute tasks. Its support for DirectX 12 Ultimate and Vulkan 1.4, alongside its RT and Tensor cores, positions it for modern professional workloads, including ray-traced rendering and AI inference. The 4 GB of GDDR6 memory and 96.00 GB/s bandwidth provide a more substantial memory pool for complex scenes and datasets. The PCIe 4.0 x8 interface ensures faster data transfer from the host system. The RTX A400’s active production status also guarantees driver updates and long-term availability.

The AMD Radeon R7 M465 has no benchmark wins. Its only advantage is historical, being a product of its time. Its lower power draw and simpler architecture might be sufficient for very basic display output or legacy applications that do not require modern features. However, even in this context, its 2 GB of memory and 36.00 GB/s bandwidth are severe limitations. The R7 M465 is a product that should have been retired; it is outclassed by every modern part, including the RTX A400’s nearest rivals like the Intel Iris Pro Graphics 6200, which is 0.6% faster than the RTX A400, or the AMD Radeon R5 M435, which is 0.3% faster than the R7 M465. The data shows a clear path: the RTX A400 is the only viable choice for any future-oriented application, while the R7 M465 is a legacy part with no discernible strengths in the current landscape.
