AMD Instinct MI300 vs Intel Arc A380M Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Instinct MI300 versus the Intel Arc A380M. Both products have an empty head-to-head benchmark array, and neither side registers a win in the winsA or winsB fields. The average benchmark score for both entries is 0, and both sit at the 50th percentile against all GPUs in the database. This absence of direct comparative measurements means the analysis must rely entirely on the specification differences and architectural characteristics recorded for each part.

Without benchmark scores, the closest quantitative comparison available comes from the compute throughput figures. The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 performance, while the Intel Arc A380M delivers 4.096 TFLOPS. That places the MI300 at approximately 11.7 times the FP32 throughput of the Arc A380M, a ratio derived directly from the recorded values. In FP16, the MI300 again lists 47.87 TFLOPS with a 1:1 ratio, whereas the Arc A380M lists 8.192 TFLOPS with a 2:1 ratio, meaning the MI300 holds a 5.8 times advantage in raw FP16 throughput.

The texture rate figures reinforce the same direction. The MI300 records 1,496.0 GTexel/s against the Arc A380M's 128.0 GTexel/s, a factor of roughly 11.7, consistent with the FP32 gap. The pixel rate comparison inverts, however, because the MI300 records 0 MPixel/s while the Arc A380M records 64.00 GPixel/s. This reflects a fundamental difference in what the two products are designed to output.

Memory bandwidth shows the largest relative disparity. The MI300 accesses 5.32 TB/s across an 8192-bit HBM3 interface, while the Arc A380M accesses 186.0 GB/s across a 96-bit GDDR6 interface. Converting both to the same unit, the MI300 provides approximately 28.6 times the bandwidth of the Arc A380M. The memory capacity difference is also substantial: 128 GB on the MI300 versus 6 GB on the Arc A380M.

The Arc A380M has no direct win in any recorded benchmark, but its pixel rate and ray tracing capabilities represent areas where it delivers measurable output where the MI300 records none. The MI300 lists no RT cores, while the Arc A380M lists 8 RT cores. The MI300 lists 0 ROPs, while the Arc A380M lists 32 ROPs. These are not performance wins in the conventional sense, but they indicate functional capabilities that the MI300 does not implement.

Architecture Differences

The two processors come from different manufacturers and target entirely different compute domains. AMD builds the Instinct MI300 on the CDNA 3.0 architecture using the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. Intel builds the Arc A380M on the Xe-HPG architecture using the DG2-128 chip, fabricated on a 6 nm process, also at TSMC. The process node difference (5 nm versus 6 nm) contributes to the transistor density gap: the MI300 packs 150.4 million transistors per square millimeter, while the Arc A380M achieves 45.9 million per square millimeter.

The raw transistor counts differ by an order of magnitude. The MI300 contains 153,000 million transistors on a 1017 mm² die, while the Arc A380M contains 7,200 million transistors on a 157 mm² die. That is roughly 21 times more transistors on the MI300, and the die area is about 6.5 times larger. The density figures confirm that the MI300 uses a denser process and a much larger physical implementation.

The memory subsystems reflect the divergent design goals. The MI300 uses 128 GB of HBM3 with an 8192-bit bus and 5.32 TB/s bandwidth. The Arc A380M uses 6 GB of GDDR6 with a 96-bit bus and 186.0 GB/s bandwidth. The memory clock differs as well: the MI300 runs at 1300 MHz with 5.2 Gbps effective throughput, while the Arc A380M runs at 1937 MHz with 15.5 Gbps effective throughput. The higher per-pin data rate on the Arc A380M cannot compensate for the much narrower bus and smaller total capacity.

The compute pipelines are structured differently. The MI300 has 14,080 shading units and 880 TMUs, with no ROPs listed. The Arc A380M has 1,024 shading units, 64 TMUs, and 32 ROPs. The MI300 lists no RT cores, while the Arc A380M includes 8 RT cores. Neither part lists tensor cores in the database. The clock speeds also differ: the MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz, while the Arc A380M has a base clock of 1550 MHz and a boost clock of 2000 MHz.

Power and interface specifications separate the two further. The MI300 has a TDP of 600 W and requires a 1000 W suggested PSU, using 2x 8-pin power connectors. The Arc A380M has a TDP of 35 W, with no power connector or PSU requirement listed because it ships as an MXM Module using the MXM-A (3.1) bus interface. The MI300 uses PCIe 5.0 x16. The MI300 has no display outputs, while the Arc A380M's outputs are listed as "Portable Device Dependent."

The API support differs completely. The MI300 lists DirectX, OpenGL, and Vulkan as N/A, meaning it is not a graphics-oriented part. The Arc A380M lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 belongs to the Instinct (MIx) generation with a predecessor of Radeon Instinct, while the Arc A380M belongs to the Alchemist (Arc 3 Mobile) generation with no predecessor recorded.

Where Each One Wins

The data indicates that the AMD Instinct MI300 wins decisively in raw compute throughput, memory capacity, memory bandwidth, and transistor resources. Its FP32 output of 47.87 TFLOPS dwarfs the Arc A380M's 4.096 TFLOPS. Its texture rate of 1,496.0 GTexel/s dwarfs the Arc A380M's 128.0 GTexel/s. Its 128 GB of HBM3 memory and 5.32 TB/s bandwidth provide a storage and data movement capacity that the Arc A380M's 6 GB and 186.0 GB/s cannot approach. For any workload that depends on massive parallel floating-point computation or very large data sets, the MI300 is the clear choice based on the recorded specifications.

The Intel Arc A380M wins in areas that the MI300 does not implement at all. It has a pixel rate of 64.00 GPixel/s, whereas the MI300 records 0 MPixel/s. It has 32 ROPs, whereas the MI300 lists 0. It has 8 RT cores, whereas the MI300 lists none. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the MI300 lists no graphics APIs. It has display outputs (portable device dependent), whereas the MI300 has no outputs. It also operates at a much lower power envelope, 35 W versus 600 W, and uses a mobile MXM form factor rather than a PCIe slot.

The clock speed comparison also favors the Arc A380M on a per-cycle basis. Its base clock of 1550 MHz and boost clock of 2000 MHz are higher than the MI300's 1000 MHz base and 1700 MHz boost. The Arc A380M also has a higher effective memory data rate of 15.5 Gbps per pin versus 5.2 Gbps on the MI300. These advantages indicate that the Arc A380M is built for lower-latency, higher-frequency operation within a constrained power budget, while the MI300 relies on massive parallelism and wide memory interfaces.

The FP16 ratio differs as well. The MI300 lists FP16 at the same 47.87 TFLOPS as FP32 (1:1 ratio), meaning it does not gain extra throughput from reduced precision. The Arc A380M lists FP16 at 8.192 TFLOPS versus 4.096 TFLOPS FP32 (2:1 ratio), meaning it doubles its throughput when using FP16. This makes the Arc A380M relatively more efficient in mixed-precision workloads, although its absolute FP16 output remains far below the MI300's.

The Verdict

The recorded data describes two products with almost no functional overlap. The AMD Instinct MI300 is a compute accelerator with no graphics APIs, no display outputs, no ROPs, and no ray tracing hardware. Its strengths are FP32 throughput at 47.87 TFLOPS, texture rate at 1,496.0 GTexel/s, memory capacity at 128 GB, and memory bandwidth at 5.32 TB/s. It consumes 600 W and requires a 1000 W suggested PSU, using PCIe 5.0 x16. It is built on a 5 nm process with 153,000 million transistors.

The Intel Arc A380M is a mobile graphics processor with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, 8 RT cores, 32 ROPs, and a pixel rate of 64.00 GPixel/s. It consumes 35 W and uses an MXM-A (3.1) interface, fitting into portable devices. Its memory is 6 GB of GDDR6 with 186.0 GB/s bandwidth, and its FP32 output is 4.096 TFLOPS. It is built on a 6 nm process with 7,200 million transistors.

For a workload that requires massive numerical computation, large memory residency, or extremely high bandwidth, the MI300 is the only option with the recorded resources to handle it. For a workload that requires rendering, ray tracing, graphics API compatibility, or display output, the Arc A380M is the only option that implements those features. Neither part can substitute for the other in its respective domain. The MI300's 0 MPixel/s pixel rate and N/A API entries disqualify it from graphics tasks, and the Arc A380M's 4.096 TFLOPS FP32 and 186.0 GB/s bandwidth fall far short of the MI300's compute and memory capacity for data-center scale workloads.

The release dates sit close together, with the MI300 released on 2023-01-03 and the Arc A380M on 2023-01-23. The MI300 belongs to the Instinct (MIx) generation, following Radeon Instinct. The Arc A380M belongs to the Alchemist (Arc 3 Mobile) generation with no predecessor. The MI300's production status is not recorded, while the Arc A380M's production status is listed as Active.
