Texture fill rate follows the same pattern: the MI300A delivers 1,915.2 GTexel/s versus 128.0 GTexel/s for the Intel card. Memory bandwidth favors the AMD part overwhelmingly, with 5.32 TB/s compared to 186.0 GB/s. These metrics position the MI300A for large-scale simulation, AI training, and scientific workloads where massive parallel processing and high-bandwidth memory access are critical.

The Intel Arc A380E x2 wins in areas tied to traditional graphics and embedded deployment. Its pixel rate of 64.00 GPixel/s contrasts sharply with the MI300A's 0 MPixel/s, meaning the Intel card can actually rasterize frames for display. The Arc supports a full API stack including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the AMD part has no graphics API support. The Intel card also provides 8 display outputs, enabling multi-monitor industrial visualization. Its compact 265 mm length, 127 mm height, and 20 mm width fit into standard single-slot systems, unlike the OAM Module form factor of the MI300A.

Clock speeds tell a different story. The Arc A380E x2 runs at a flat 2000 MHz for both base and boost, while the MI300A has a 1000 MHz base clock and 2100 MHz boost clock. The Intel card's higher sustained base clock suggests consistent performance in steady-state workloads, whereas the AMD module relies on boost behavior for peak throughput.

Architecture Differences

The MI300A is built on CDNA 3.0 architecture with the chip designated as Aqua Vanjaram. This architecture prioritizes compute density over graphics features, which explains the absence of ROPs, RT cores, and display outputs. The 5 nm TSMC process allows for 150.4 million transistors per square millimeter, enabling 153,000 million transistors on a 1017 mm² die. The design targets data center acceleration with PCIe 5.0 x16 connectivity and HBM3 memory.

The Arc A380E x2 uses Xe-HPG architecture with the DG2-128 chip, part of the Alchemist generation within the Arc 3 lineup. This architecture includes 8 RT cores for ray tracing, 32 ROPs for rasterization, and supports DirectX 12 Ultimate. The 6 nm process yields 45.9 million transistors per square millimeter, totaling 7,200 million transistors on a 157 mm² die. The Intel card uses PCIe 4.0 x8 and GDDR6 memory, reflecting its embedded and edge positioning.

Transistor density differences are stark: the MI300A packs 150.4M transistors per mm² versus 45.9M for the Arc A380E x2. This 3.3 times density advantage stems from the more advanced 5 nm node. The MI300A also features FP16 compute capability, though the database does not list a specific FP16 TFLOPS figure for it, while the Arc A380E x2 delivers 8.192 TFLOPS FP16 with a 2:1 ratio relative to FP32.

The MI300A belongs to the Instinct (MIx) generation with a predecessor of Radeon Instinct. The Arc A380E x2 sits in the Alchemist generation with Xe Graphics as its predecessor and Battlemage as its successor, confirming its lifecycle stage.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two products. The wins count stands at zero for both sides, and no average benchmark scores or percentile rankings beyond a neutral 50th percentile for each are recorded. This absence of comparative data reflects their fundamentally different market segments.

However, the recorded specification data allows for direct mathematical comparisons. The FP32 throughput of the MI300A is 61.29 TFLOPS, which is 14.96 times the 4.096 TFLOPS of the Arc A380E x2. Memory bandwidth shows a 28.6 times advantage for the AMD part: 5.32 TB/s versus 186.0 GB/s. Texture fill rate is 14.96 times higher on the MI300A (1,915.2 GTexel/s versus 128.0 GTexel/s).

The Arc A380E x2 holds advantages in specific areas. Its pixel rate of 64.00 GPixel/s is infinitely higher than the MI300A's 0 MPixel/s, since the AMD module lacks ROPs entirely. The Intel card's memory clock of 1937 MHz exceeds the AMD memory clock of 1300 MHz, though the effective bandwidth difference reverses this due to bus width. The Arc also has a higher base clock (2000 MHz versus 1000 MHz), which matters for workloads that do not scale with boost behavior.

Power efficiency comparisons, while not directly recorded, can be derived from the data. The MI300A delivers 61.29 TFLOPS at 750 W, which calculates to 81.72 GFLOPS per watt. The Arc A380E x2 delivers 4.096 TFLOPS at 130 W, which is 31.51 GFLOPS per watt. The AMD part is 2.6 times more efficient in FP32 per watt, despite its much higher absolute power draw. Similarly, memory bandwidth per watt favors the MI300A: 5.32 TB/s divided by 750 W equals 7.09 GB/s per watt, versus 186.0 GB/s divided by 130 W equals 1.43 GB/s per watt for the Intel card.

Transistor efficiency shows a different picture. The MI300A achieves 61.29 TFLOPS from 153,000 million transistors, or 0.0004 TFLOPS per million transistors. The Arc A380E x2 achieves 4.096 TFLOPS from 7,200 million transistors, or 0.00057 TFLOPS per million transistors. The Intel architecture extracts more compute per transistor, though the absolute scale difference dominates any efficiency comparison.

Die size efficiency favors the AMD part. The MI300A produces 61.29 TFLOPS from 1017 mm², or 60.27 GFLOPS per mm². The Arc A380E x2 produces 4.096 TFLOPS from 157 mm², or 26.09 GFLOPS per mm². The 5 nm process enables 2.3 times higher compute density per area.

The Verdict

The data points to two products with no meaningful overlap in purpose. The AMD Instinct MI300A is a compute accelerator for high-performance computing environments. Its 128 GB HBM3 memory, 5.32 TB/s bandwidth, and 61.29 TFLOPS FP32 performance target workloads that require massive data movement and parallel processing. The absence of display outputs and graphics APIs confirms this role. The 750 W TDP and OAM Module form factor require specialized server infrastructure.

The Intel Arc A380E x2 serves embedded and edge applications that need graphics output. Its 8 display outputs, DirectX 12 Ultimate support, and 64.00 GPixel/s pixel rate enable multi-screen visualization. The 130 W TDP and single-slot design with one 6-pin connector fit standard industrial systems. The end-of-life production status indicates this is a mature product nearing the end of its availability.

Users requiring raw compute throughput should select the MI300A. The data shows a 15 times FP32 advantage, 28.6 times memory bandwidth advantage, and 15 times texture rate advantage. The 5 nm process delivers 3.3 times higher transistor density. The 153,000 million transistor count enables the 1,915.2 GTexel/s texture rate that no embedded GPU can approach.

Users needing graphics rendering and display output should select the Arc A380E x2. It is the only option with ROPs, RT cores, and API support. The 265 mm length and 127 mm height fit standard expansion slots. The 2000 MHz constant clock provides predictable performance. The 32 ROPs and 64.00 GPixel/s pixel rate handle rasterization tasks that the MI300A cannot perform at all.

The database records no benchmark scores or rival comparisons for either product, leaving the specification sheet as the primary evidence. The percentile rankings for both sit at 50, indicating neutral positioning within the broader GPU landscape. The verdict rests on the recorded differences: one card computes but cannot display, the other displays but computes at a fraction of the scale. Each wins in its intended domain.
