Architecture Differences

The AMD Instinct MI300X is built on the CDNA 3.0 architecture, designed specifically for compute workloads rather than graphics output. Its chip, codenamed Aqua Vanjaram, uses a 5 nm process from TSMC and integrates 153,000 million transistors across a 1017 mm² die. The transistor density is 150.4M per mm². This accelerator has 19456 shading units, 1216 texture mapping units, and zero ROPs, which aligns with its lack of display outputs. The MI300X uses HBM3 memory totaling 192 GB, with an 8192-bit bus width enabling 5.32 TB/s of bandwidth. Its FP32 performance reaches 81.72 TFLOPS, and FP16 is also 81.72 TFLOPS with a 1:1 ratio. The card operates at a 750 W TDP and uses an OAM module slot width with no power connectors, relying on the host system's power delivery.

The Intel Arc B570, by contrast, is a consumer graphics card from the Battlemage generation, using the Xe2-HPG architecture. Its chip, BMG-G21, is also fabricated on a 5 nm TSMC process but contains 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm². The B570 has 2304 shading units, 144 TMUs, 80 ROPs, and 18 ray tracing cores. It features 10 GB of GDDR6 memory on a 160-bit bus, providing 380.0 GB/s of bandwidth. The card's FP32 output is 11.52 TFLOPS, while FP16 reaches 23.04 TFLOPS with a 2:1 ratio. It has a 150 W TDP, a dual-slot form factor, and a single 8-pin power connector. The B570 includes 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The most significant architectural difference lies in the memory subsystem and compute scale. The MI300X's HBM3 memory provides 5.32 TB/s bandwidth, which is roughly 14 times the B570's 380.0 GB/s. The shading unit count also differs dramatically, with the MI300X having over eight times the B570's 2304 units. The MI300X has no ROPs or display outputs, confirming its role as a compute-only accelerator, while the B570 is a fully featured graphics card with ray tracing and display connectivity. The MI300X also lacks any recorded API support for graphics, whereas the B570 supports current graphics standards.

Head-to-Head Benchmarks

The database contains a single direct comparison between these two parts: Geekbench OpenCL. In this test, the AMD Instinct MI300X scores 317994, and the Intel Arc B570 scores 83514. The MI300X wins by 280.8%, a margin that reflects the massive difference in compute resources. The MI300X's score places it at the 100th percentile of all GPUs in the database, meaning it outperforms every other recorded GPU. The B570, at the 65th percentile, sits near the middle of the distribution.

To contextualize the MI300X's result, the nearest rivals in the database include the NVIDIA B200 with an average score of 345482, which is 8% higher, and the NVIDIA H200 NVL at 334891, which is 5% higher. The MI300X beats the NVIDIA L40S, which scores 295763, by 7.5%, and the NVIDIA RTX 6000 Ada Generation, which scores 287237, by 10.7%. This shows the MI300X is competitive with top-tier data center accelerators, though slightly behind the B200 and H200 NVL in this specific workload.

For the Intel Arc B570, the nearest rivals are much closer in performance. The NVIDIA GeForce RTX 3070 Mobile scores 20534, a 0.1% difference from the B570's 20556 average. The Intel Arc A750 scores 20582, which is 0.1% lower than the B570. The NVIDIA Quadro M4000M scores 20480, a 0.4% difference, and the AMD Radeon R9 M390X scores 20662, which is 0.5% higher than the B570. These margins indicate the B570 performs in line with mid-range mobile and older desktop GPUs, with no clear dominance over any direct rival.

The wins tally in the database shows 1 win for the AMD Instinct MI300X and 0 wins for the Intel Arc B570. This is consistent with the single benchmark result. The MI300X's lead is absolute in this comparison, but the two products are not designed for the same tasks. The B570's benchmark suite includes multiple tests such as 3DMark Steel Nomad DX12, Passmark DirectX 9/10/11/12, Passmark G2D, G3D, and GPU Compute, none of which are shared with the MI300X. The MI300X only has the Geekbench OpenCL result, which limits the scope of direct comparison.

The Verdict

The data indicates that the AMD Instinct MI300X is the clear performance leader in the only shared benchmark, delivering a 280.8% higher Geekbench OpenCL score than the Intel Arc B570. Its 100th percentile ranking versus the B570's 65th percentile reinforces this gap. For compute-heavy data center workloads, the MI300X's 192 GB of HBM3 memory, 5.32 TB/s bandwidth, and 81.72 TFLOPS FP32 performance make it a top-tier accelerator, as shown by its proximity to the NVIDIA B200 and H200 NVL in the database.

The Intel Arc B570, however, serves a completely different purpose. It is a consumer graphics card with 10 GB of GDDR6 memory, 18 ray tracing cores, and full display outputs. Its nearest rivals in the database are all within 0.5% of its average score, indicating it performs on par with the NVIDIA GeForce RTX 3070 Mobile and Intel Arc A750. The B570's 150 W TDP and dual-slot design make it suitable for standard desktop systems, whereas the MI300X requires an OAM module slot and a 1150 W PSU.

Users requiring compute acceleration without display output should select the MI300X based on its recorded performance. Users needing a graphics card with modern API support, ray tracing, and display connectivity should choose the Arc B570. The two products do not compete in the same market segment, and the benchmark data reflects that separation. The MI300X's lack of DirectX, OpenGL, and Vulkan support disqualifies it from gaming or graphics tasks, while the B570's lower compute throughput limits its data center appeal.
