Architecture Differences

The fundamental architecture tells the story of the performance gap. The AMD Radeon R7 M370 is built on GCN 1.0, a design introduced with the "Gem System (R7 M)" family. It packs 950 million transistors into a 77 mm² die, resulting in 12.3 million transistors per square millimeter. In contrast, the NVIDIA RTX A400 is built on the Ampere architecture and the "Workstation Ampere (Ax000)" generation. It packs a far larger 8,700 million transistors onto a 200 mm² die, achieving a density of 43.5 million per mm².

The core configuration reinforces this gap. The R7 M370 has 384 shading units, 24 texture mapping units and 8 ROPs. The RTX A400 has 768 shading units, 24 RT cores, 6 tensor cores, 16 ROPs and 24 texture mapping units. Clock speeds also favor the newer card. The R7's base clock is 875 MHz with a boost of 960 MHz and memory at 900 MHz (3.6 Gbps effective). The RTX A400 has a base clock of 1417 MHz, a boost of 1762 MHz, and memory at 1500 MHz (12 Gbps effective).

The interface bus is also different: the R7 M370 is a PCIe 3.0 x8 part, while the RTX A400 is a PCIe 4.0 x8 part. The R7 supports no display outputs, while the A400 supports 4x mini-DisplayPort 1.4a. The R7's production status is End-of-life; its predecessor is "Solar System" and its successor is "Polaris Mobile". The A400's predecessor is "Quadro Turing", and its successor is "Workstation Ada".

The Verdict

From the recorded data, this is not a close contest. The NVIDIA RTX A400 wins on every benchmark. In the Geekbench OpenCL test, the R7 M370 scores 7063 while the A400 scores 22844, a 69.1% difference. The Vulkan test shows a similar margin: 6465 for the R7 vs 22237 for the A400, a 70.9% difference. Across all recorded tests, the A400's average benchmark score is 6078, compared to 6764 for the A400. The R7 M370 sits in the 38th percentile of all GPUs, while the RTX A400 sits in the 35th percentile. The closest rivals in the data are the AMD FirePro M5100 (avg 6830), NVIDIA GeForce GT 1010 (avg 6698), AMD Radeon R7 M460 (avg 6612), and NVIDIA GeForce GTX 675M (avg 6946). The A400 is 0.5% behind the Quadro P2000, 0.6% ahead of the Intel Iris Pro 6200, and 1% behind the AMD Radeon 760M in these comparisons.

Which should be chosen? The answer depends entirely on the workload. For any compute-heavy, modern API or ray-tracing use case, the RTX A400 is the only choice, given its massive shading, RT, and tensor core advantages, and its raw performance lead. The older R7 M370 is a much simpler, slower part, and its end-of-life status makes it a poor option for new system deployment. The data makes the decision straightforward: the NVIDIA RTX A400 is the superior part in almost all measurable ways.

Specification Differences

The recorded specs show two very different mobile and workstation parts. The AMD Radeon R7 M370 has 2 GB of GDDR5 memory, a 128-bit bus, and 57.60 GB/s of bandwidth. The NVIDIA RTX A400 has 4 GB of GDDR6 memory on a 64-bit bus with 96.00 GB/s of bandwidth. The clock speeds also differ: the R7 is at 875 MHz base/960 MHz boost (memory at 900 MHz), while the A400 is at 1417 MHz base/1762 MHz boost (memory at 1500 MHz).

On the rendering front, the R7 M370 has 384 shading units, 24 TMUs, and 8 ROPs. The RTX A400 doubles the shading units to 768, retains 24 TMUs but doubles ROPs to 16, and adds 24 tensor cores plus 6 RT cores. These extra unit types are key for AI and ray tracing workloads.

The R7 M370 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, with a pixel rate of 7.680 GPixel/s and texture rate of 23.04 GTexel/s. FP32 compute is 737.3 GFLOPS. The RTX A400 supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4, and a pixel rate of 28.19 GPixel/s and texture rate of 42.29 GTexel/s. FP32 is 2.706 TFLOPS (FP16 is the same 2.706 TFLOPS, a 1:1 ratio).

Head-to-Head Benchmarks

The benchmark data shows a dominant trend. In the Geekbench OpenCL test, the R7 M370 scores 7063 while the RTX A400 scores 22844. This is a 69.1% difference in favor of the NVIDIA card. The Vulkan test shows a similar story: 6465 for the R7 versus 22237 for the A400, a 70.9% lead. All recorded wins (2 out of 2 in the head-to-head comparison) go to the NVIDIA RTX A400.

These scores are not close. The 69.1% lead in OpenCL is a massive gap. The 70.9% lead in Vulkan confirms that the A400 is in a completely different performance class. This is not a slight improvement, it is a generational leap. The R7 M370, with its lower core, older memory, and no specialized cores, cannot compete with the A400's modern feature set.

Where Each One Wins

Given the complete data domination, the use case split is clear.

Choose the AMD Radeon R7 M370 only in one specific situation: when you simply need a mobile GPU with a specific legacy feature set and the workload is low-end. Its end-of-life status (with a 2015 release date) means it lacks modern features, and its 69.1% and 70.9% benchmark gaps are not a minor issue.

The NVIDIA RTX A400 is the clear pick for any modern workload. It wins in compute (2.706 TFLOPS FP32 vs 737.3 GFLOPS), pixel throughput (28.19 vs 7.68 GPixel/s), texture throughput (42.29 vs 23.04 GTexel/s), and memory bandwidth (96.00 vs 57.60 GB/s). More importantly, it has dedicated tensor cores and RT cores, necessary for the AI and ray tracing. Its 4 GB VRAM is double the R7's 2 GB, and it has a much more advanced feature set (DisplayPort 1.4a outputs, PCIe 4.0, 250W PSU, single-slot form factor). The R7 is simply outclassed in every way. The data indicates that users of the RTX A400 will be able to take full advantage of the modern graphics APIs and compute software, while users of the R7 M370 will be restricted to a legacy workload.
