AMD Instinct MI355X vs Intel Arc Pro B370 Comparison

Head-to-Head Benchmarks

The recorded benchmark database contains no direct head-to-head benchmark scores for the AMD Instinct MI355X and the Intel Arc Pro B370. Both entries show an average benchmark score of 0, with no individual benchmark results listed. The wins counter for each part is also 0, indicating that no comparative performance measurements have been logged for this pairing.

This absence of measured data is itself informative. The two products occupy entirely different segments of the hardware landscape, and the database's percentile ranking places both at the 50th percentile among all GPUs, but that figure is derived from the default baseline, not from any recorded performance data.

The AMD Instinct MI355X delivers a raw compute specification of 78.64 TFLOPS for FP32 operations. The Intel Arc Pro B370 delivers 6.144 TFLOPS for FP32 operations. The difference in raw compute throughput is substantial, with the AMD part offering more than twelve times the FP32 throughput on paper.

For FP16 workloads, the AMD Instinct MI355X maintains 78.64 TFLOPS at a 1:1 ratio with FP32. The Intel Arc Pro B370 doubles its throughput to 12.29 TFLOPS at a 2:1 ratio. Even with Intel's rate advantage, the AMD part still leads by a factor of more than six in FP16 compute.

Texture processing shows a similar gap. The AMD Instinct MI355X reaches 2,457.6 GTexel/s, while the Intel Arc Pro B370 reaches 96.00 GTexel/s. Pixel throughput tells a different story: the AMD part is listed at 0 MPixel/s because it has no ROPs, while the Intel part delivers 48.00 GPixel/s from its 20 ROPs.

The AMD Instinct MI355X has no display outputs. The Intel Arc Pro B370 has display outputs that are portable device dependent. The AMD part targets compute workloads, while the Intel part integrates into a system as an IGP.
