AMD Radeon Instinct MI300X vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Radeon Instinct MI300X and the Intel Arc A380E x2. The head-to-head benchmark array is empty, and neither product has an average benchmark score or a list of nearest rivals. This means the comparison must be built entirely from the specification data and the qualitative positioning of each product within their respective categories.

What the data does show is a fundamental divide in design intent. The AMD Radeon Instinct MI300X is a data center accelerator with a 750 W TDP, an OAM module form factor, and no display outputs. The Intel Arc A380E x2 is a single-slot embedded graphics card with a 130 W TDP, eight mini-DisplayPort 2.0 outputs, and a production status marked as end-of-life. One is built for compute throughput, the other for multi-display rendering in embedded systems.

The MI300X delivers 81.72 TFLOPS of FP32 performance and 653.7 TFLOPS of FP16 performance with an 8:1 ratio. The Arc A380E x2 delivers 4.096 TFLOPS of FP32 and 8.192 TFLOPS of FP16 with a 2:1 ratio. In raw FP32 throughput, the MI300X is roughly 20 times higher. In FP16, the MI300X is approximately 80 times higher, though the ratio difference means the MI300X's FP16 output is achieved through a different execution path.

Memory capacity follows the same pattern. The MI300X has 192 GB of HBM3 memory on an 8192-bit bus, yielding 10.3 TB/s of bandwidth. The Arc A380E x2 has 6 GB of GDDR6 memory on a 96-bit bus, yielding 186.0 GB/s of bandwidth. The MI300X offers 32 times the memory capacity and roughly 55 times the memory bandwidth.

The texture rate tells a similar story: 2,553.6 GTexel/s for the MI300X versus 128.0 GTexel/s for the Arc A380E x2. The pixel rate is inverted, however. The Arc A380E x2 has a pixel rate of 64.00 GPixel/s, while the MI300X is listed at 0 MPixel/s because its ROP count is zero. The MI300X is not designed to rasterize or output frames. The Arc A380E x2 has 32 ROPs and 8 RT cores, making it capable of traditional graphics rendering and ray tracing.

Both products share a 50th percentile ranking against all GPUs in the database, but this percentile is based on an average benchmark score of zero for both, so it does not indicate comparable performance. It only reflects that neither has recorded benchmark data.

The Verdict

The data supports a clear division of roles. The AMD Radeon Instinct MI300X is for compute workloads that demand massive memory capacity, extreme bandwidth, and high FP32/FP16 throughput. The Intel Arc A380E x2 is for embedded graphics applications that require multiple display outputs, standard rasterization, and low power draw.

The MI300X uses a 5 nm process from TSMC with 153,000 million transistors on a 1017 mm² die. The Arc A380E x2 uses a 6 nm process from TSMC with 7,200 million transistors on a 157 mm² die. The MI300X has 19,456 shading units and 1,216 texture mapping units. The Arc A380E x2 has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores. The MI300X has no ROPs, no RT cores, and no display outputs.

The MI300X requires a suggested PSU of 1150 W and uses no power connectors because it is an OAM module. The Arc A380E x2 uses a single 6-pin power connector and has a suggested PSU of 300 W. The MI300X uses PCIe 5.0 x16, while the Arc A380E x2 uses PCIe 4.0 x8. The Arc A380E x2 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X has no listed API support for DirectX, OpenGL, or Vulkan.

The release dates differ: the MI300X launched on 2023-12-05, and the Arc A380E x2 launched on 2024-03-31. The Arc A380E x2 is marked end-of-life, with a successor named Battlemage. The MI300X has no successor listed, and its predecessor is FirePro Data Center. The Arc A380E x2's predecessor is Xe Graphics.

A user needing compute acceleration for large data sets should select the MI300X. A user needing embedded graphics with multiple display outputs should select the Arc A380E x2. The data does not support any crossover between these roles.
