AMD Instinct MI355X vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Instinct MI355X and the Intel Arc B370. The AMD Instinct MI355X has no benchmark scores listed, with an average benchmark score of 0 and a percentile rank of 50 among all GPUs. The Intel Arc B370, by contrast, has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 1184, placing it in the 5th percentile of all GPUs.

The Intel Arc B370’s nearest rivals in the database show a tight cluster of scores. The ATI Mobility Radeon HD 5570 leads with an average score of 1186, putting the Arc B370 0.2% behind. The ATI Radeon HD 5770 scores 1190, a 0.5% gap, while the AMD Radeon HD 7650M reaches 1192, 0.7% ahead. On the lower side, the AMD FirePro M2000 posts 1168, which the Arc B370 beats by 1.4%. These deltas are all within a narrow band, indicating that the Arc B370’s single benchmark result places it in a performance tier populated by older discrete and mobile graphics solutions. The absence of any benchmark data for the MI355X means no comparative percentage deltas can be calculated between the two products.

The MI355X’s 50th percentile ranking, despite having zero recorded scores, is a database artifact rather than a performance measurement. The Arc B370’s 5th percentile ranking is directly tied to its 1184 score. With no overlapping test results, the head-to-head comparison rests entirely on architectural and specification differences rather than measured performance outcomes.

The Verdict

The data presents two products with almost no overlap in purpose or measured capability. The AMD Instinct MI355X is a high-power accelerator with 288 GB of HBM3e, 8.19 TB/s bandwidth, 78.64 TFLOPS FP32, and a 1400 W TDP. It targets compute workloads that require massive memory capacity and throughput, with no display output and no consumer graphics API support. Its 50th percentile ranking is unbacked by any benchmark score, so its relative standing in the database is undefined.

The Intel Arc B370 is a low-power integrated GPU with a 25 W TDP, 6.144 TFLOPS FP32, 12.29 TFLOPS FP16, and 10 ray tracing cores. Its single 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile, directly competing with older ATI and AMD parts like the ATI Mobility Radeon HD 5570 (0.2% ahead) and the AMD FirePro M2000 (1.4% behind). The Arc B370 supports modern graphics APIs and portable device displays, making it suitable for integrated graphics in mobile or embedded contexts.

For applications requiring dedicated compute acceleration with enormous memory pools, the MI355X is the only option with the recorded specifications to handle such workloads. For conventional graphics rendering, the Arc B370 has the API support, ray tracing cores, and a measurable benchmark score. The absence of shared benchmark data means no direct performance comparison can be made; the choice depends entirely on the workload type, with the MI355X serving compute and the Arc B370 serving graphics.
