AMD Instinct MI350X vs Intel Arc A580 Comparison

Where Each One Wins

The AMD Instinct MI350X and Intel Arc A580 occupy entirely different segments of the hardware landscape, and the recorded data reflects that divide clearly. The MI350X is a compute-oriented accelerator with no display outputs, no graphics API support, and a benchmark profile that yields zero recorded scores. The Arc A580, by contrast, is a conventional graphics card with active production status, DirectX 12 Ultimate support, and three recorded benchmark results.

The MI350X wins on raw compute scale. Its FP32 throughput is 72.09 TFLOPS, which is 5.9 times the Arc A580's 12.29 TFLOPS. The FP16 figure is similarly lopsided: 72.09 TFLOPS with a 1:1 ratio for the MI350X versus 24.58 TFLOPS with a 2:1 ratio for the Arc A580. The MI350X also delivers 2,252.8 GTexel/s of texture rate versus 384.0 GTexel/s for the Arc A580. The memory subsystem is where the gap becomes extreme: the MI350X has 288 GB of HBM3e on an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The Arc A580 has 8 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s. That is a 16-fold difference in memory capacity and a 16-fold difference in bandwidth.

The Arc A580 wins on practical graphics functionality. It has 24 ray tracing cores, 96 ROPs, and a pixel rate of 192.0 GPixel/s. The MI350X has zero ROPs and a pixel rate of 0 MPixel/s. The Arc A580 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4; the MI350X reports N/A for all three graphics APIs. The Arc A580 provides display outputs (1x HDMI 2.1, 3x DisplayPort 2.0), while the MI350X has no outputs. The Arc A580 also has a benchmark percentile of 87 versus all GPUs, while the MI350X sits at the 50th percentile with an average benchmark score of 0.

The MI350X uses a 3 nm TSMC process with 185,000 million transistors on a 2380 mm² die. The Arc A580 uses a 6 nm TSMC process with 21,700 million transistors on a 406 mm² die. The MI350X has 16,384 shading units and 1,024 TMUs; the Arc A580 has 3,072 shading units and 192 TMUs. The MI350X is an OAM module with no power connectors, while the Arc A580 is a dual-slot card with 2x 8-pin power connectors. The MI350X targets a 1000 W TDP with a suggested PSU of 1400 W; the Arc A580 targets 175 W with a suggested PSU of 450 W.

The Verdict

The data indicates that these two products should never be compared as alternatives. The MI350X is an accelerator with no graphics pipeline, no display capability, and no standard benchmark scores. Its percentile rank of 50 with an average benchmark score of 0 places it outside the conventional GPU ranking system entirely. The Arc A580, with its 87th percentile rank and average benchmark score of 57,756, is a functional graphics card that competes in the mainstream segment.

For compute workloads that require massive memory capacity and bandwidth, the MI350X is the clear choice. Its 288 GB of HBM3e and 8.19 TB/s bandwidth dwarf anything the Arc A580 can offer. The 72.09 TFLOPS of FP32 performance, matching FP16 at a 1:1 ratio, indicates a design optimized for dense compute rather than graphics rendering. The MI350X also uses a more advanced 3 nm process and carries 185,000 million transistors, reflecting a fundamentally different engineering objective.

For graphics rendering, gaming, or any workload requiring display output, the Arc A580 is the only viable option between the two. It has the full graphics feature set: ray tracing cores, ROPs, DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6. Its benchmark scores confirm functional performance: 2,229 in 3DMark Steel Nomad DX12, 91,657 in Geekbench OpenCL, and 79,381 in Geekbench Vulkan. The nearest rivals in the database show the Arc A580 sitting within 1.1 percent of the AMD Radeon RX 6950 XT, 0.8 percent behind the Intel Arc A570M, 0.6 percent behind the AMD Radeon RX 5600 OEM, and 0.7 percent ahead of the AMD Radeon RX 9070 GRE.

The MI350X has no nearest rivals recorded, which reinforces its position outside the typical GPU comparison framework. The choice is dictated by the workload: compute acceleration points to the MI350X, graphics output points to the Arc A580.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty in the recorded data. No direct comparative tests exist between the MI350X and the Arc A580. The MI350X has no benchmark scores at all, while the Arc A580 has three. This absence of overlap is itself informative: the MI350X does not run the standard graphics benchmarks that the Arc A580 participates in.

The Arc A580's 3DMark Steel Nomad DX12 score of 2,229 reflects its DirectX 12 Ultimate capability. Its Geekbench OpenCL score of 91,657 and Geekbench Vulkan score of 79,381 show compute performance through graphics APIs. The MI350X cannot be measured in these tests because it has no graphics API support, no Vulkan, no DirectX, no OpenGL.

The nearest rival data for the Arc A580 provides context for its performance tier. The AMD Radeon RX 5600 OEM scores 58,085 on average, which is 0.6 percent ahead of the Arc A580's 57,756. The AMD Radeon RX 9070 GRE scores 57,367, which is 0.7 percent behind. The Intel Arc A570M scores 58,239, which is 0.8 percent ahead. The AMD Radeon RX 6950 XT scores 58,392, which is 1.1 percent ahead. These deltas place the Arc A580 in a tight cluster of comparable GPUs, all within roughly one percent of each other.

The MI350X has no such comparison data. Its average benchmark score is 0, and its percentile rank of 50 indicates it falls in the middle of the database distribution only by default, not by measured performance. The FP32 throughput of 72.09 TFLOPS versus the Arc A580's 12.29 TFLOPS is a 5.9-fold advantage for the MI350X. The memory bandwidth of 8.19 TB/s versus 512.0 GB/s is a 16-fold advantage. These are the largest measurable gaps between the two products, and they reflect the MI350X's design as a memory-bound compute accelerator.

Architecture Differences

The architectural split between these two products is fundamental. The MI350X is built on CDNA 4.0 with a chip designation of MI350 256CU. The Arc A580 is built on Xe-HPG with a DG2-512 chip. The MI350X belongs to the Instinct (MIx) generation, while the Arc A580 belongs to the Alchemist (Arc 5) generation.

The compute resources differ by a factor of roughly five. The MI350X has 16,384 shading units, 1,024 TMUs, and zero ROPs. The Arc A580 has 3,072 shading units, 192 TMUs, and 96 ROPs. The MI350X has no ray tracing cores listed, while the Arc A580 has 24. The MI350X has zero pixel rate, and the Arc A580 delivers 192.0 GPixel/s.

Memory architecture is the largest differentiator. The MI350X uses HBM3e at 2000 MHz with 8 Gbps effective speed, an 8192-bit bus width, and 8.19 TB/s bandwidth. The Arc A580 uses GDDR6 at 2000 MHz with 16 Gbps effective speed, a 256-bit bus width, and 512.0 GB/s bandwidth. The MI350X has 288 GB of memory, and the Arc A580 has 8 GB.

The clock profiles also differ. The MI350X runs at a 1000 MHz base and 2200 MHz boost. The Arc A580 runs at a 1700 MHz base and 2000 MHz boost. The higher base clock on the Arc A580 reflects a graphics-oriented design, while the MI350X's higher boost clock relative to its base suggests a compute workload profile.

Power delivery and physical format differ completely. The MI350X is an OAM module with a 1000 W TDP and a suggested PSU of 1400 W. It has no power connectors because it draws power through the OAM interface. The Arc A580 is a dual-slot card with a 175 W TDP and a suggested PSU of 450 W, powered by 2x 8-pin connectors. The MI350X measures 102 mm in length and 165 mm in width; the Arc A580 has no dimensions recorded.

The bus interface also differs by one generation. The MI350X uses PCIe 5.0 x16, while the Arc A580 uses PCIe 4.0 x16.

The release dates are separated by roughly 20 months. The Arc A580 was released on 2023-10-09, and the MI350X on 2025-06-11. The Arc A580 lists its predecessor as Xe Graphics and its successor as Battlemage. The MI350X lists its predecessor as Radeon Instinct with no successor recorded. The Arc A580 has active production status; the MI350X does not have a recorded production status.
