AMD Radeon R7 M440 vs NVIDIA RTX A400 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the NVIDIA RTX A400 across the two shared benchmark tests. In Geekbench OpenCL, the RTX A400 scores 22,844 against the AMD Radeon R7 M440's 5,214, a delta of 338.1% in NVIDIA's favor. That is not a marginal gap; it is a generational chasm. The Vulkan test tells a similar story, with the RTX A400 posting 22,237 versus 5,751 for the R7 M440, a 286.7% advantage.

The magnitude of these deltas is worth pausing on. A 338% lead in OpenCL implies that the RTX A400 completes compute workloads in roughly a quarter of the time required by the R7 M440, assuming linear scaling. For Vulkan, the 286.7% gap means the NVIDIA card is nearly four times faster in that API. The AMD part does not win a single head-to-head test, and the database records winsA as 2 and winsB as 0.

Context from the average benchmark scores reinforces this. The RTX A400 carries an average score of 6,078 across all its recorded tests, while the R7 M440 averages 5,483. That overall average difference of roughly 11% is far smaller than the head-to-head deltas, which suggests the R7 M440's other benchmark results (had they been recorded) might have narrowed the aggregate gap. However, for the two tests where both parts have data, the RTX A400 is overwhelmingly dominant.

The percentile rankings provide additional framing. The RTX A400 sits in the 35th percentile of all GPUs, while the R7 M440 sits in the 32nd percentile. Both are near the lower-middle of the distribution, but the RTX A400 edges ahead even in that broader context. The nearest rivals for each part also show a clustering effect: the RTX A400's closest competitor is the NVIDIA GeForce MX230 at 6,077 average score (0% delta), while the R7 M440's nearest rival is the NVIDIA GeForce MX130 at 5,508 (-0.5% delta). This indicates that both parts compete in the entry-level space, but the RTX A400 does so from a higher baseline.

Architecture Differences

The two GPUs come from fundamentally different architectural eras. The NVIDIA RTX A400 uses the Ampere architecture, built around the GA107 chip on an 8 nm Samsung process. It packs 8,700 million transistors into a 200 mm² die, yielding a transistor density of 43.5 million per square millimeter. The AMD Radeon R7 M440, in contrast, uses the GCN 3.0 architecture with the Meso chip on a 28 nm TSMC process. It contains 1,550 million transistors on a 125 mm² die, with a density of 12.4 million per square millimeter.

The transistor count difference is stark: the RTX A400 has over five times as many transistors. The process node difference, 8 nm versus 28 nm, explains much of this. The RTX A400's Ampere architecture also introduces hardware features that simply did not exist on the older GCN 3.0 design. The RTX A400 includes 6 ray tracing cores and 24 tensor cores, while the R7 M440 has none of either. These are not just spec sheet entries; they enable entirely different workloads, from hardware-accelerated ray tracing to AI inference via tensor operations.

The shading infrastructure also differs substantially. The RTX A400 has 768 shading units, 24 texture mapping units (TMUs), and 16 render output units (ROPs). The R7 M440 has 320 shading units, 20 TMUs, and 8 ROPs. The RTX A400's compute capabilities are reflected in its 2.706 TFLOPS FP32 performance, while the R7 M440 manages only 570.2 GFLOPS. Both run FP16 at a 1:1 ratio with FP32, but the absolute numbers are worlds apart.

API support also differs. The RTX A400 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The R7 M440 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The RTX A400's DirectX 12 Ultimate designation means it supports features like mesh shaders and variable rate shading, which are absent from the R7 M440's feature set. The RTX A400 also uses PCIe 4.0 x8, while the R7 M440 uses the older PCIe 3.0 x8 interface.

Specification Differences

The specification table reveals several clear divergences between the two parts. The RTX A400 has a base clock of 1417 MHz and a boost clock of 1762 MHz, while the R7 M440 has no recorded base or boost clock values. Memory clocks differ as well: the RTX A400 runs at 1500 MHz (12 Gbps effective), while the R7 M440 runs at 900 MHz (1800 Mbps effective).

Memory type marks a major difference: the RTX A400 uses 4 GB of GDDR6 on a 64-bit bus, giving 96.00 GB/s bandwidth. The R7 M440 also has 4 GB, but it is DDR3 on a 64-bit bus, yielding only 14.40 GB/s. That is a 6.7x bandwidth advantage for the RTX A400, which directly impacts texture streaming and compute workloads.

The pixel and texture rates tell a similar story. The RTX A400 achieves 28.19 GPixel/s and 42.29 GTexel/s, while the R7 M440 manages 7.128 GPixel/s and 17.82 GTexel/s. The RTX A400's TDP is listed at 50 W, while the R7 M440 has no recorded TDP. The RTX A400 is a single-slot card with no power connectors and a suggested PSU of 250 W. The R7 M440 is an integrated GPU (IGP) with no power connector information.

Physical and interface differences round out the list. The RTX A400 measures 163 mm in length and 69 mm in height, with four mini-DisplayPort 1.4a outputs. The R7 M440 has no recorded dimensions and its display outputs are described as "Portable Device Dependent," reflecting its mobile/integrated nature. The RTX A400 connects via PCIe 4.0 x8; the R7 M440 uses PCIe 3.0 x8. Production status also differs: the RTX A400 is Active, the R7 M440 is End-of-life.

Where Each One Wins

The RTX A400 wins in every measured category. In compute, its OpenCL score of 22,844 crushes the R7 M440's 5,214. In graphics API performance, its Vulkan score of 22,237 dwarfs the R7 M440's 5,751. The RTX A400 also leads in pixel rate, texture rate, FP32 throughput, and memory bandwidth by wide margins. For any workload that depends on raw shading power, compute throughput, or memory bandwidth, the RTX A400 is the clear choice.

The R7 M440's only "win" is contextual. It is an integrated GPU designed for portable devices, which means it consumes no dedicated slot space and has no external power connectors. Its 28 nm GCN 3.0 architecture is simpler and older, but for basic display output and light 2D workloads, it may suffice. The R7 M440's 4 GB of DDR3 memory is the same capacity as the RTX A400's GDDR6, though the bandwidth is far lower. In scenarios where the host system already includes the R7 M440 as an IGP and the workload is minimal, it offers a zero-cost graphics solution. But in any performance comparison, the RTX A400 wins outright.

The data also suggests the RTX A400 is more future-proof. Its Active production status, 2024 release date, and support for DirectX 12 Ultimate and Vulkan 1.4 mean it can handle modern APIs. The R7 M440's End-of-life status and 2016 release date place it firmly in legacy territory. For users running older software that predates DirectX 12, the R7 M440 might suffice, but that is a narrow use case.

The Verdict

The benchmark data is unambiguous: the NVIDIA RTX A400 outperforms the AMD Radeon R7 M440 by massive margins in every shared test. The 338.1% OpenCL lead and 286.7% Vulkan lead are not incremental improvements; they represent entirely different performance classes. The RTX A400's newer architecture, higher transistor count, dedicated ray tracing and tensor cores, and vastly superior memory bandwidth all contribute to this result.

Who should pick the RTX A400? Anyone running compute workloads, modern game engines, or GPU-accelerated applications that leverage DirectX 12 Ultimate or Vulkan 1.4. Its 96.00 GB/s memory bandwidth and 2.706 TFLOPS FP32 performance make it a capable entry-level workstation card. Its Active production status and 2024 release date mean it will receive driver support for years to come.

Who should pick the R7 M440? Only those who have no choice, such as users with a laptop that ships with this integrated GPU and no discrete option. Its 14.40 GB/s bandwidth and 570.2 GFLOPS FP32 performance are sufficient for basic display output and legacy 2D applications, but the data shows it is outclassed by virtually every modern competitor. The R7 M440's 32nd percentile ranking and End-of-life status suggest it should be avoided where any alternative exists.

The verdict is straightforward: the RTX A400 is the superior product by every measurable metric in the database. The R7 M440 is a relic of an older era, and the numbers confirm it cannot compete. For any user prioritizing performance, the RTX A400 is the only rational choice.
