AMD Radeon 760M vs NVIDIA RTX A400 Comparison

The NVIDIA RTX A400 and AMD Radeon 760M occupy a similar performance tier, with average benchmark scores of 6078 and 6019 respectively, yet they achieve this parity through entirely different architectures and design philosophies. The data shows a near-dead heat in overall average score, with the RTX A400 holding a 1% lead over the Radeon 760M in the nearestRivals comparison, making the choice between them a matter of workload-specific strengths rather than raw aggregate performance.

Head-to-Head Benchmarks

The RTX A400 takes a decisive victory in the majority of tested workloads, winning 6 of the 9 head-to-head comparisons. Its most dominant win comes in Passmark DirectX 10, where it scores 32 against the Radeon 760M’s 19, a 68.4% advantage. This pattern continues in legacy API tests: in Passmark DirectX 9, the A400 posts 87 versus 65, a 33.8% lead. These results indicate that NVIDIA’s architecture retains strong performance in older DirectX pipelines, which can matter for compatibility with legacy professional applications.

In modern API workloads, the gap narrows but still favors the A400. Passmark DirectX 12 shows a modest 8% win for the A400 (27 vs 25), while Passmark DirectX 11 is the exception, with the Radeon 760M taking a 28.8% lead (52 vs 37). The A400 also edges out the Radeon 760M in OpenCL, scoring 22844 versus 20255, a 12.8% advantage, and in Passmark G3D, where it scores 5983 against 5310, a 12.7% lead. The G2D test is nearly a tie, with the A400 ahead by just 1% (899 vs 890).

The Radeon 760M’s wins are fewer but significant. Its largest victory is in Geekbench Vulkan, where it scores 30336 against the A400’s 22237, a commanding 26.7% margin in the opposite direction. This is a substantial reversal from the OpenCL result and highlights a major API-level divergence. The Radeon 760M also wins Passmark GPU Compute, scoring 2840 versus 2557, a 10% advantage, and as noted, Passmark DirectX 11. In the aggregate, the A400’s average benchmark score of 6078 places it 0.5% ahead of the Quadro P2000 and 0% from the GeForce MX230, while the Radeon 760M’s 6019 average sits 0.3% behind the RX 6400 and 0.5% behind the Quadro P2000.

Where Each One Wins

The RTX A400 is the stronger choice for DirectX 9, 10, and 12 workloads, as well as OpenCL, G2D, and G3D tasks. Its 33.8% lead in DirectX 9 and 68.4% lead in DirectX 10 suggest that it is better suited for applications that rely on older graphics APIs, which are common in certain industrial, CAD, and legacy visualization tools. The 12.8% OpenCL advantage points to better general-purpose compute performance in that framework, which is often used in scientific and engineering simulations. The 12.7% G3D lead indicates a more capable overall 3D rendering engine for standard graphics tasks.

The Radeon 760M is the clear winner for Vulkan-based applications, where its 26.7% margin is the largest of any head-to-head result. This makes it the better option for modern games and applications that leverage Vulkan’s low-overhead design. Its 10% lead in Passmark GPU Compute suggests it has an edge in certain compute-heavy workloads, particularly those that are not bound by OpenCL. The DirectX 11 win, with a 28.8% margin, is also notable, as DirectX 11 remains the baseline for many business and productivity applications and a large portion of the existing game library.

The percentile data places both GPUs at the 35th percentile of all GPUs, confirming that neither is a high-end part. However, the nature of their wins is distinct: the A400 spreads its advantages across a wider range of API types, while the Radeon 760M concentrates its strengths in fewer, but sometimes larger, margins. For a user with a known API requirement, this distinction is critical. A workload built on Vulkan will favor the Radeon 760M decisively, while a mixed workload of DirectX and OpenCL tasks will tilt toward the RTX A400.

The Verdict

From the data, the RTX A400 is the more versatile card for professional and workstation use. It wins the aggregate benchmark average, 6078 versus 6019, and claims victory in 6 of 9 head-to-head tests, including the important OpenCL and G3D categories. Its consistent performance across DirectX 9, 10, and 12, combined with the 12.8% OpenCL lead, makes it the safer pick for a broad range of business, engineering, and design applications that do not rely on Vulkan. The 4 GB of dedicated GDDR6 memory, while modest, is a discrete resource that does not compete with system memory, which is a structural advantage for consistent performance.

The Radeon 760M is the pick for Vulkan-centric workloads. Its 26.7% lead in Geekbench Vulkan is the single largest margin in the entire comparison, and its 10% win in GPU Compute indicates that users prioritizing those specific tasks will see tangible benefits. The 28.8% DirectX 11 lead is also significant for users stuck on that API. However, its system-shared memory means performance is dependent on the host system’s RAM configuration, a factor that is not present with the A400’s dedicated memory. For a user building a system with a clear Vulkan focus, the Radeon 760M is the data-backed choice; for everyone else, the RTX A400’s broader wins make it the default recommendation.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The NVIDIA RTX A400 uses the GA107 chip based on the Ampere architecture, manufactured by Samsung on an 8 nm process. It contains 8,700 million transistors on a 200 mm² die, resulting in a transistor density of 43.5M per mm². The AMD Radeon 760M uses the Phoenix chip based on RDNA 3.0, manufactured by TSMC on a 4 nm process. It packs 25,390 million transistors on a 178 mm² die, giving it a much higher transistor density of 142.6M per mm².

The A400 has 768 shading units, 24 TMUs, and 16 ROPs, while the Radeon 760M has fewer shading units at 512, but more TMUs at 32, and the same 16 ROPs. The Radeon 760M has 8 ray tracing cores, compared to 6 on the A400, and it also has a significantly higher boost clock of 2599 MHz versus 1762 MHz on the A400. The A400 includes 24 tensor cores, a feature the Radeon 760M does not list, which gives it dedicated AI acceleration hardware.

The architectural differences manifest in the raw throughput numbers. The Radeon 760M achieves 5.323 TFLOPS of FP32 and FP16 performance, nearly double the A400’s 2.706 TFLOPS. It also has a higher pixel rate of 41.58 GPixel/s versus 28.19 GPixel/s, and a much higher texture rate of 83.17 GTexel/s versus 42.29 GTexel/s. Despite these compute advantages, the A400 wins more benchmark tests, showing that raw throughput does not directly translate to wins in all API-specific workloads.

Specification Differences

The most notable specification difference is the memory subsystem. The RTX A400 has a dedicated 4 GB of GDDR6 memory on a 64-bit bus, with 96.00 GB/s of bandwidth and a memory clock of 1500 MHz (12 Gbps effective). The Radeon 760M has no dedicated memory; it uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent or shared. This is a fundamental design difference that affects performance predictability.

The TDP figures are also starkly different. The RTX A400 has a TDP of 50 W and requires a 250 W suggested power supply, while the Radeon 760M has a TDP of just 15 W and has no suggested PSU listed, as it is an integrated graphics processor (IGP). The A400 is a single-slot card with dimensions of 163 mm in length and 69 mm in height, with no power connectors needed. The Radeon 760M is an IGP with no dimensions or power connectors, relying entirely on the motherboard.

The display outputs differ as well. The A400 provides 4x mini-DisplayPort 1.4a outputs, while the Radeon 760M’s display outputs are motherboard dependent. The A400 has a base clock of 1417 MHz and a boost clock of 1762 MHz, while the Radeon 760M has a lower base clock of 800 MHz but a much higher boost clock of 2599 MHz. The A400’s bus interface is PCIe 4.0 x8, and the Radeon 760M shares the same PCIe 4.0 x8 interface. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A400 was released on 2024-04-15, while the Radeon 760M was released earlier on 2024-01-30.
