AMD Instinct MI355X vs Intel Arc B570 Comparison

Where Each One Wins

The AMD Instinct MI355X and Intel Arc B570 occupy entirely different segments of the GPU landscape, and the recorded data reflects that separation clearly. The MI355X is a compute-oriented accelerator with no display outputs, no graphics API support, and zero benchmark entries in the database. Its percentile rank of 50 among all GPUs places it squarely in the middle of the distribution, but that percentile is based on no recorded benchmark scores, meaning it is a placeholder rather than a measured result.

The Arc B570, by contrast, is a fully functional graphics card with active production status and a robust set of benchmark results. It achieves a 65th percentile ranking among all GPUs, which places it ahead of the majority of recorded graphics hardware. Its average benchmark score of 20,556 points comes from ten distinct tests spanning DirectX 9 through DirectX 12, Vulkan, OpenCL, and compute workloads. The closest rival in the database is the NVIDIA GeForce RTX 3070 Mobile, which scores 20,534 points, a delta of 0.1 percent. The Intel Arc A750 trails by a similar margin at 20,582 points, a delta of negative 0.1 percent.

The MI355X wins in raw compute capacity. Its FP32 throughput of 78.64 TFLOPS dwarfs the Arc B570's 11.52 TFLOPS, a sixfold advantage. Memory bandwidth tells a similar story: 8.19 TB/s versus 380.0 GB/s. The MI355X carries 288 GB of HBM3e memory across an 8192-bit bus, while the Arc B570 uses 10 GB of GDDR6 on a 160-bit bus. These are not competing products in any practical sense, but the database records show that the MI355X is designed for massive parallel workloads, whereas the Arc B570 targets conventional graphics rendering and general-purpose compute.

The Arc B570 wins in every measurable graphics workload because the MI355X has no graphics pipeline at all. The Arc B570's pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s are functional numbers, while the MI355X reports 0 MPixel/s and 2,457.6 GTexel/s. The MI355X has no raster operations units, no ray tracing cores, and no API support for DirectX, OpenGL, or Vulkan. The Arc B570 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it a complete solution for interactive graphics.

Architecture Differences

The two chips diverge fundamentally in their underlying designs. The MI355X uses the MI350 256CU chip built on CDNA 4.0 architecture, fabricated on a 3 nm process at TSMC. It contains 185,000 million transistors on a die size of 2,380 mm², yielding a transistor density of 77.7 million per square millimeter. The Arc B570 uses the BMG-G21 chip on Xe2-HPG architecture, built on a 5 nm process, also at TSMC. Its transistor count is 19,600 million on a 272 mm² die, giving a density of 72.1 million per square millimeter. The MI355X packs nearly ten times the transistors into nearly nine times the die area.

The MI355X is a pure compute accelerator with 16,384 shading units and 1,024 texture mapping units. It has zero raster operation units, zero ray tracing cores, and no tensor core count listed. The Arc B570 has 2,304 shading units, 144 texture mapping units, 80 raster operation units, and 18 ray tracing cores. The MI355X supports FP16 at a 1:1 ratio with FP32, meaning both run at 78.64 TFLOPS. The Arc B570 runs FP16 at a 2:1 ratio, delivering 23.04 TFLOPS versus its 11.52 TFLOPS FP32.

Memory architectures reflect their divergent purposes. The MI355X uses HBM3e with 288 GB capacity, 8192-bit bus width, and 8.19 TB/s bandwidth. Memory clock is 2000 MHz with 8 Gbps effective. The Arc B570 uses GDDR6 with 10 GB capacity, 160-bit bus width, and 380.0 GB/s bandwidth. Memory clock is 2375 MHz with 19 Gbps effective. The MI355X's power envelope is 1400 W with a suggested 1800 W power supply, while the Arc B570 draws 150 W with a 450 W suggested PSU. The MI355X uses an OAM module slot width with no power connectors, indicating a board-integrated design. The Arc B570 is a dual-slot card with a single 8-pin connector.

Process node differences explain some of the density gap. The 3 nm node on the MI355X allows tighter packing than the 5 nm node on the Arc B570, though the density numbers are close at 77.7 versus 72.1 million transistors per square millimeter. The MI355X's die is 2380 mm², nearly nine times the Arc B570's 272 mm². Physical dimensions also differ: the MI355X measures 102 mm in length and 165 mm in width, while the Arc B570 measures 272 mm in length and 115 mm in height.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark results in the database for these two products. The MI355X has no benchmark entries at all, while the Arc B570 has ten recorded tests. Direct comparison is therefore limited to architectural specifications and the Arc B570's relative position among its nearest rivals.

The Arc B570's best single-test score comes from Geekbench Vulkan at 96,844 points. Its Geekbench OpenCL score is 83,514 points. In PassMark tests, the G3D score is 14,195 points, and the GPU compute score is 7,281 points. DirectX tests show 164 points for DirectX 9, 118 points for DirectX 11, 72 points for DirectX 12, and 65 points for DirectX 10. The G2D score is 661 points. The 3DMark Steel Nomad DX12 test returns 2,649 points.

The MI355X's raw specifications indicate compute dominance, but no measured scores exist to confirm real-world performance. Its FP32 output of 78.64 TFLOPS is 6.8 times the Arc B570's 11.52 TFLOPS. Its texture rate of 2,457.6 GTexel/s is 6.8 times the Arc B570's 360.0 GTexel/s. Its memory bandwidth of 8.19 TB/s is 21.6 times the Arc B570's 380.0 GB/s.

The Arc B570's benchmark average of 20,556 points places it between the RTX 3070 Mobile at 20,534 points and the Arc A750 at 20,582 points. The delta percentages are minimal, within half a percent across all four nearest rivals. This indicates tight clustering among mid-range GPUs in the database. The MI355X's percentile of 50 with no scores is not comparable to the Arc B570's measured 65th percentile.

The data shows two products with no overlap in purpose. The MI355X is a data-center accelerator with enormous memory and compute resources but no graphics capability. The Arc B570 is a consumer graphics card with full API support and measurable performance across a range of tests. Their only shared attribute is the TSMC foundry, though on different process nodes.
