AMD Instinct MI300A vs NVIDIA GeForce RTX 3050 A Mobile Comparison

The Verdict

The database comparison between the AMD Instinct MI300A and the NVIDIA GeForce RTX 3050 A Mobile places two radically different products side by side. The MI300A is a data center accelerator with no display outputs, no graphics API support, and a 750 W power envelope. The RTX 3050 A Mobile is an end-of-life laptop GPU with full DirectX 12 Ultimate support and a 45 W power envelope. The recorded data shows no head-to-head benchmark wins for either part, and the MI300A has no benchmark scores in the database, while the RTX 3050 A Mobile carries an average benchmark score of 8746 and sits at the 44th percentile among all GPUs.

The MI300A should be selected by users who need massive memory capacity and raw compute throughput in a server context. Its 128 GB of HBM3 memory, 8192-bit bus, and 61.29 TFLOPS FP32 performance put it in a class that the RTX 3050 A Mobile cannot approach. The RTX 3050 A Mobile should be selected for portable systems requiring standard graphics APIs, ray tracing cores, and tensor cores. The data shows the RTX 3050 A Mobile is comparable to older mid-range desktop cards, with its nearest rival being the NVIDIA GeForce GTX 460 v2 at a 0% delta, and the AMD Radeon R9 M265X trailing by 1.2%. The MI300A, by contrast, has no nearest rivals in the database, reflecting its position as a compute accelerator rather than a conventional graphics card.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the MI300A and the RTX 3050 A Mobile. The MI300A has an empty benchmark array, an average benchmark score of 0, and a percentile rank of 50 among all GPUs. The RTX 3050 A Mobile has eight recorded benchmark scores. Its strongest result is a Geekbench OpenCL score of 52998. In Passmark tests, it scores 152 in DirectX 9, 94 in DirectX 11, 61 in DirectX 10, and 55 in DirectX 12. Its Passmark G3D score is 11664, its G2D score is 526, and its GPU compute score is 4419.

The RTX 3050 A Mobile's average benchmark score of 8746 places it at the 44th percentile among all GPUs. Its nearest rival, the NVIDIA GeForce GTX 460 v2, has an average score of 8743 with a 0% delta. The AMD Radeon R9 M265X sits slightly ahead at 8851 with a -1.2% delta, meaning the RTX 3050 A Mobile trails that card by 1.2%. The AMD Radeon Pro WX 5100 scores 8863 with a -1.3% delta. The NVIDIA Quadro P2200 scores 8686, putting the RTX 3050 A Mobile ahead by 0.7%.

For the MI300A, the absence of benchmark scores means no direct performance comparison is possible from the recorded data. Its percentile rank of 50 against all GPUs is a neutral placement, but this is not backed by any benchmark result in the database. The specification data indicates a compute capability far beyond the RTX 3050 A Mobile, but the benchmark database does not capture any MI300A scores to quantify that gap.

Where Each One Wins

The MI300A wins on raw compute specifications. Its 61.29 TFLOPS FP32 is roughly 12.7 times the RTX 3050 A Mobile's 4.813 TFLOPS.
