AMD Instinct MI300 vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the AMD Instinct MI300 and the Intel Arc A380E. Both entries report an average benchmark score of zero and a percentile rank of 50 against all GPUs. With zero benchmark wins recorded for either side, the numerical comparison relies entirely on the architectural and specification data captured in the database.

The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 compute, while the Intel Arc A380E delivers 4.096 TFLOPS. That places the MI300 at 11.7 times the raw floating-point throughput of the Arc A380E. In FP16, the MI300 maintains 47.87 TFLOPS with a 1:1 ratio, whereas the Arc A380E reaches 8.192 TFLOPS with a 2:1 ratio. The MI300's FP16 output is 5.8 times higher. Texture rate tells a similar story: the MI300 processes 1,496.0 GTexel/s versus 128.0 GTexel/s for the Arc A380E, a factor of 11.7. The MI300's pixel rate is listed as 0 MPixel/s, while the Arc A380E outputs 64.00 GPixel/s; this reflects the MI300's lack of any display outputs or raster output pipeline.

Memory capacity and bandwidth heavily favor the MI300. The Instinct card carries 128 GB of HBM3 across an 8192-bit bus, yielding 5.32 TB/s of bandwidth. The Arc A380E uses 6 GB of GDDR6 on a 96-bit bus, producing 186.0 GB/s. The MI300's bandwidth is 28.6 times higher, and its capacity is 21.3 times greater. Memory clock rates are recorded at 1300 MHz (5.2 Gbps effective) for the MI300 and 1937 MHz (15.5 Gbps effective) for the Arc A380E, so the Intel part runs its memory at a higher effective data rate despite the far narrower bus.

Transistor counts differ by an order of magnitude. The MI300 integrates 153,000 million transistors on a 1017 mm² die using a 5 nm TSMC process, yielding a density of 150.4 million transistors per square millimeter. The Arc A380E contains 7,200 million transistors on a 157 mm² die using a 6 nm TSMC process, for a density of 45.9 million per square millimeter. The MI300 has 21.25 times more transistors and a 6.5 times larger die.

Power envelopes diverge sharply. The MI300 has a TDP of 600 W with a suggested power supply of 1000 W and two 8-pin connectors. The Arc A380E has a TDP of 75 W, no power connectors, and a suggested power supply of 250 W. The MI300 consumes 8 times the thermal design power. The Arc A380E is single-slot, while the MI300's slot width is not recorded.

The Verdict

The data shows two products built for entirely different workloads. The AMD Instinct MI300 is an accelerator-class part with no display outputs, no DirectX, OpenGL, or Vulkan support recorded, and a 600 W power envelope. The Intel Arc A380E is a conventional graphics card with four DisplayPort 2.0 outputs, DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4, and an end-of-life production status.

For compute-heavy tasks such as large-scale FP32 or FP16 processing, memory-bound workloads, or high-bandwidth data movement, the MI300 is the only viable choice based on the recorded specifications. Its 5.32 TB/s bandwidth and 128 GB capacity are unmatched by the Arc A380E's 186.0 GB/s and 6 GB. The MI300 also uses PCIe 5.0 x16, while the Arc A380E uses PCIe 4.0 x8, doubling the interface width and moving to a newer generation.

For any task requiring graphical output, display connectivity, or standard graphics API support, the Arc A380E is the functional option. The MI300 records no display outputs and no graphics API support, making it unsuitable for rendering to a monitor. The Arc A380E's 64.00 GPixel/s pixel rate and 8 ray tracing cores provide actual rasterization and RT capability, which the MI300 lacks entirely.

The production statuses also differ: the Arc A380E is listed as end-of-life with a successor named as Battlemage, while the MI300's production status is not recorded. The MI300's predecessor is Radeon Instinct; the Arc A380E's predecessor is Xe Graphics. Release dates place the MI300 in January 2023 and the Arc A380E in March 2024.

Neither product has benchmark entries in the database, so percentile ranks remain equal at 50. The verdict from the data is straightforward: the MI300 targets data-center-scale compute, and the Arc A380E targets embedded or entry-level graphics with display output.

Where Each One Wins

The AMD Instinct MI300 wins decisively in raw compute throughput. Its FP32 rate of 47.87 TFLOPS and FP16 rate of 47.87 TFLOPS (1:1) dwarf the Arc A380E's 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16 (2:1). The MI300 also holds the advantage in texture processing with 1,496.0 GTexel/s versus 128.0 GTexel/s.

Memory-bound applications favor the MI300 without contest. The 5.32 TB/s bandwidth over an 8192-bit HBM3 interface provides 28.6 times the bandwidth of the Arc A380E's GDDR6 setup. Capacity at 128 GB versus 6 GB means the MI300 can hold far larger datasets in local memory, reducing reliance on host transfers. The MI300's 8192-bit bus width is 85.3 times wider than the Arc A380E's 96-bit bus.

The Intel Arc A380E wins in every metric related to display and graphics output. It provides four DisplayPort 2.0 connectors, a pixel rate of 64.00 GPixel/s, and support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 lists no outputs and marks all graphics APIs as not applicable. The Arc A380E's 32 ROPs and 8 ray tracing cores enable rasterization and ray-traced rendering, while the MI300 records 0 ROPs and no RT core count.

Efficiency metrics favor the Arc A380E based on the recorded power data. At 75 W TDP, the Arc A380E delivers 4.096 TFLOPS FP32, while the MI300 at 600 W delivers 47.87 TFLOPS. The Arc A380E achieves 54.6 GFLOPS per watt, and the MI300 achieves 79.8 GFLOPS per watt, so the MI300 is actually more compute-efficient per watt, but the Arc A380E requires far less total power and no external connectors. The Arc A380E also fits in a single slot with dimensions of 254 mm length, 127 mm height, and 20 mm width, whereas the MI300 is 267 mm long and 111 mm tall with no width recorded.

The Arc A380E's process node is older (6 nm versus 5 nm) and its transistor density is lower (45.9M per mm² versus 150.4M per mm²), but its smaller die (157 mm² versus 1017 mm²) makes it far cheaper to produce, though no pricing data is recorded.

Architecture Differences

The AMD Instinct MI300 is built on the CDNA 3.0 architecture with the Aqua Vanjaram chip, fabricated on a 5 nm TSMC process. The Intel Arc A380E uses the Xe-HPG architecture with the DG2-128 chip, fabricated on a 6 nm TSMC process. Both use TSMC as the foundry, but the process nodes differ by one generation.

Transistor integration separates the two designs. The MI300 packs 153,000 million transistors into a 1017 mm² die, achieving a density of 150.4 million transistors per square millimeter. The Arc A380E contains 7,200 million transistors on a 157 mm² die, for a density of 45.9 million per square millimeter. The MI300's die is 6.5 times larger and holds 21.25 times more transistors.

Compute unit configurations differ substantially. The MI300 has 14,080 shading units, 880 texture mapping units, and 0 ROPs. The Arc A380E has 1,024 shading units, 64 TMUs, and 32 ROPs. The MI300 has no recorded ray tracing cores or tensor cores; the Arc A380E includes 8 ray tracing cores but no tensor core count is listed.

Memory architectures are fundamentally different. The MI300 uses HBM3 with a 128 GB capacity, an 8192-bit bus, and 5.32 TB/s bandwidth at 1300 MHz (5.2 Gbps effective). The Arc A380E uses GDDR6 with 6 GB capacity, a 96-bit bus, and 186.0 GB/s bandwidth at 1937 MHz (15.5 Gbps effective). The MI300's memory clock is lower in effective data rate, but its bus width and total bandwidth vastly exceed the Arc A380E.

Clock behavior also differs. The MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz. The Arc A380E runs at a flat 2000 MHz for both base and boost. The Arc A380E's higher clock speed does not compensate for its far smaller compute array.
