AMD Instinct MI300A vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark results between the AMD Instinct MI300A and the Intel Arc B570, so a direct score-for-score comparison is not possible from recorded measurements. The AMD Instinct MI300A has no benchmark entries in the database, while the Intel Arc B570 has ten recorded tests. This absence of overlapping data means the head-to-head comparison must rely on architectural throughput metrics and the Arc B570's measured performance against its own nearest rivals.

For the Intel Arc B570, the recorded benchmark suite shows a balanced profile across synthetic workloads. The highest single score is Geekbench Vulkan at 96,844, followed by Geekbench OpenCL at 83,514. In Passmark testing, the GPU Compute score is 7,281, while the DirectX 11 score is 118 and DirectX 9 is 164. The 3DMark Steel Nomad DX12 result is 2,649. These figures place the Arc B570 at the 65th percentile among all GPUs in the database, with an average benchmark score of 20,556.

The nearest rivals for the Arc B570 are tightly clustered. The NVIDIA GeForce RTX 3070 Mobile averages 20,534, a delta of 0.1% relative to the Arc B570. The Intel Arc A750 averages 20,582, a delta of -0.1%. The NVIDIA Quadro M4000M averages 20,480, a delta of 0.4%, and the AMD Radeon R9 M390X averages 20,662, a delta of -0.5%. These deltas are all within one percentage point, indicating that the Arc B570 sits in a very narrow performance band where small score differences separate the four rivals. The Arc B570's average score is essentially indistinguishable from these competitors in aggregate terms.

The AMD Instinct MI300A has zero recorded benchmarks and zero wins in the head-to-head field. Its percentile rank is 50, and its average benchmark score is zero. The Arc B570 holds all ten recorded benchmark entries and therefore all wins in the measured category, though this reflects data availability rather than a direct performance verdict. The MI300A's raw throughput specifications, however, dwarf the Arc B570's measured results. The MI300A delivers 61.29 TFLOPS FP32, while the Arc B570 delivers 11.52 TFLOPS FP32. The MI300A's texture rate is 1,915.2 GTexel/s versus the Arc B570's 360.0 GTexel/s. Memory bandwidth differs by an order of magnitude: 5.32 TB/s for the MI300A versus 380.0 GB/s for the Arc B570.

Where Each One Wins

The Intel Arc B570 wins in every recorded benchmark category simply because it has recorded data. Its Passmark G3D score of 14,195 and Passmark G2D score of 661 indicate a functional graphics pipeline with 2D and 3D acceleration. The DirectX legacy tests (9, 10, 11, 12) show scores ranging from 65 to 164, with DirectX 9 being the highest at 164. The Geekbench compute tests show strong OpenCL and Vulkan performance relative to the card's own 3DMark result. The 3DMark Steel Nomad DX12 score of 2,649 is the modern API test in the set.

The AMD Instinct MI300A wins on raw specification dominance across nearly every measurable hardware dimension. It has 14,592 shading units versus 2,304 for the Arc B570. Texture mapping units number 912 versus 144. The MI300A has 128 GB of HBM3 memory on an 8,192-bit bus, while the Arc B570 has 10 GB of GDDR6 on a 160-bit bus. The MI300A's pixel rate is recorded as 0 MPixel/s, which reflects its lack of display outputs (the card has no display connectors), whereas the Arc B570 has a pixel rate of 200.0 GPixel/s and supports display output via 1x HDMI 2.1a and 3x DisplayPort 2.1.

For compute-oriented workloads, the MI300A is the clear winner on paper. Its FP32 throughput of 61.29 TFLOPS is roughly 5.3 times the Arc B570's 11.52 TFLOPS. The texture rate is similarly lopsided. The MI300A's memory bandwidth of 5.32 TB/s is approximately 14 times the Arc B570's 380.0 GB/s. These differences indicate that the MI300A is designed for data-center scale compute, while the Arc B570 targets client graphics and modest compute tasks.

The MI300A is a compute accelerator with no display pipeline, no ROPs, and no graphics API support. The Arc B570 is a consumer graphics card with a full rasterization pipeline, ray tracing hardware, and display outputs. The MI300A's memory subsystem is built for massive bandwidth (5.32 TB/s) and capacity (128 GB), suited to large model inference or training workloads. The Arc B570's memory subsystem is smaller (10 GB) and lower bandwidth (380.0 GB/s), suited to client rendering and lighter compute tasks.

The release dates differ by roughly 13 months: the MI300A launched on 2023-12-05, and the Arc B570 launched on 2025-01-15. The MI300A has no launch MSRP recorded; the Arc B570 has a launch MSRP of 219 USD. The MI300A's transistor count is 153,000 million versus 19,600 million for the Arc B570, a ratio of approximately 7.8 to 1. The die size ratio is 1,017 mm² versus 272 mm², approximately 3.7 to 1. The transistor density is roughly 2.1 times higher on the MI300A (150.4M per mm² versus 72.1M per mm²).

The MI300A's power connectors are recorded as none, indicating an OAM module that receives power through the socket or carrier board. The Arc B570 uses a standard 1x 8-pin PCIe power connector. The MI300A's slot width is OAM Module, which is not a standard PCIe slot format; the Arc B570 is a Dual-slot card. The bus interface differs as well: PCIe 5.0 x16 for the MI300A versus PCIe 4.0 x8 for the Arc B570, meaning the MI300A has double the lane count and a newer generation for data transfer.
