AMD Instinct MI325X vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI325X and the Intel Arc A380E x2 contains no head-to-head benchmark results. The head-to-head benchmark array is empty, which means there are no direct performance comparisons available between these two accelerators in the database. Similarly, the individual benchmark arrays for each product are empty, and the average benchmark score for both is 0. The win counts for each product are also 0, indicating that neither device has any recorded victories over the other in any measured workload.

Without direct comparison data, the analysis must rely on the raw architectural and specification differences between the two. The AMD Instinct MI325X is positioned as a data center compute accelerator, while the Intel Arc A380E x2 is a graphics card with display outputs. The MI325X delivers 81.72 TFLOPS of FP32 performance and 81.72 TFLOPS of FP16 performance at a 1:1 ratio. The Arc A380E x2 delivers 4.096 TFLOPS of FP32 performance and 8.192 TFLOPS of FP16 performance at a 2:1 ratio. The FP32 figure for the MI325X is exactly 20 times higher than the Arc's FP32 figure, while the FP16 figure for the MI325X is approximately 10 times higher than the Arc's FP16 figure.

The texture rate shows a similar disparity. The MI325X achieves 2,553.6 GTexel/s, while the Arc A380E x2 achieves 128.0 GTexel/s. This places the MI325X roughly 20 times ahead in texture fill rate. The pixel rate is a different story: the MI325X has a pixel rate of 0 MPixel/s, while the Arc A380E x2 has a pixel rate of 64.00 GPixel/s. This is a clear indication that the MI325X is not designed for rasterized graphics output, whereas the Arc is fully equipped for pixel generation.

Memory bandwidth is another major separator. The MI325X has 6.14 TB/s of bandwidth from its 256 GB HBM3e memory on an 8192-bit bus. The Arc A380E x2 has 186.0 GB/s of bandwidth from its 6 GB GDDR6 memory on a 96-bit bus. The MI325X's bandwidth is 33 times higher than the Arc's. The memory clocks differ as well: the MI325X runs at 1500 MHz with 6 Gbps effective speed, while the Arc runs at 1937 MHz with 15.5 Gbps effective speed. Despite the Arc's faster memory clock, the MI325X's enormous bus width gives it the overwhelming bandwidth advantage.

Where Each One Wins

The AMD Instinct MI325X wins decisively in compute throughput metrics. Its FP32 performance of 81.72 TFLOPS is an order of magnitude higher than the Arc's 4.096 TFLOPS. Its FP16 performance of 81.72 TFLOPS is also roughly 10 times the Arc's 8.192 TFLOPS. The texture rate of 2,553.6 GTexel/s versus 128.0 GTexel/s confirms that the MI325X is built for massive parallel arithmetic and texture-heavy compute workloads. Memory bandwidth of 6.14 TB/s versus 186.0 GB/s gives the MI325X a 33-to-1 advantage in data movement capability, which is critical for large matrix operations and data center inference tasks.

The Intel Arc A380E x2 wins in graphics output and display functionality. It has 8 mini-DisplayPort 2.0 outputs, while the MI325X has no display outputs at all. The Arc supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI325X has no supported graphics APIs. The Arc also has a pixel rate of 64.00 GPixel/s, while the MI325X has 0 MPixel/s. The Arc includes 8 ray tracing cores, which the MI325X lacks entirely. The Arc has 32 ROPs, while the MI325X has 0 ROPs. In terms of physical installation, the Arc uses a single-slot form factor with a 1x 6-pin power connector and a suggested PSU of 300 W, while the MI325X uses an OAM Module with no power connectors and a suggested PSU of 1400 W.

In memory capacity, the MI325X has 256 GB versus the Arc's 6 GB. The MI325X uses HBM3e, the Arc uses GDDR6. The MI325X operates on a 8192-bit bus, the Arc on a 96-bit bus. The MI325X has 19,456 shading units, the Arc has 1,024. The MI325X has 1,216 TMUs, the Arc has 64. The MI325X has 153,000 million transistors on a 1017 mm² die, the Arc has 7,200 million transistors on a 157 mm² die. The MI325X has a base clock of 1000 MHz and boost clock of 2100 MHz, the Arc has a base clock of 2000 MHz and boost clock of 2000 MHz.

The Verdict

The data shows two devices built for entirely different purposes. The AMD Instinct MI325X is a data center accelerator with no display outputs, no graphics API support, and no pixel rendering capability. Its strengths are raw FP32 and FP16 compute, enormous memory capacity, and extreme bandwidth. The Intel Arc A380E x2 is a graphics card with full display output, complete graphics API support, ray tracing cores, and a conventional single-slot design with a 6-pin power connector.

For workloads that require massive parallel floating-point arithmetic, such as large-scale matrix operations or high-throughput inference, the MI325X is the clear choice based on its 81.72 TFLOPS FP32 and FP16 figures. For workloads that require rendering to displays, pixel output, or graphics API compatibility, the Arc A380E x2 is the only viable option, as the MI325X has no display outputs and no graphics API support. The Arc also supports ray tracing, which the MI325X does not.

The production status differs: the Arc is listed as end-of-life with a successor named Battlemage, while the MI325X has no production status listed and no successor named. The release dates show the MI325X was released on 2024-10-09, and the Arc was released on 2024-03-31. The predecessor for the MI325X is Radeon Instinct, and for the Arc it is Xe Graphics.

Neither product has a launch MSRP listed in the database, so no pricing information is available for either device.
