Where Each One Wins

The Radeon RX 7400 wins on every measurable compute and memory metric in the database. Its FP32 throughput of 16.49 TFLOPS is four times the Arc A380E's 4.096 TFLOPS. Texture rate follows the same pattern: 257.6 GTexel/s versus 128.0 GTexel/s, exactly double. Pixel rate shows 147.2 GPixel/s against 64.00 GPixel/s, a 2.3x advantage. The AMD card also has more shading units (1792 vs 1024), more TMUs (112 vs 64), more ROPs (64 vs 32), and more ray tracing cores (28 vs 8).

Memory bandwidth favors the Radeon RX 7400 at 288.0 GB/s versus 186.0 GB/s, and its 8 GB frame buffer exceeds the Arc A380E's 6 GB. The AMD card also offers a higher boost clock at 2300 MHz compared to the Intel card's fixed 2000 MHz.

The Arc A380E does have a few structural advantages. It is single-slot with dimensions of 254 mm length, 127 mm height, and 20 mm width, while the Radeon RX 7400 has no listed dimensions but occupies dual-slot width. The Intel card requires no external power connectors, whereas the AMD card needs one 6-pin connector. The Arc A380E also offers four DisplayPort 2.0 outputs, while the Radeon RX 7400 offers one HDMI 2.1a and three DisplayPort 2.1 outputs.

The Intel card's percentile ranking across all GPUs is 50, which places it above the Radeon RX 7400's 17th percentile. However, that percentile is computed without any benchmark scores for the Arc A380E, so it reflects structural classification rather than measured performance. The Radeon RX 7400 has an average benchmark score of 2467, while the Arc A380E has an average of 0.

Architecture Differences

The Radeon RX 7400 uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III (RX 7000) generation. The Arc A380E uses the DG2-128 chip with Xe-HPG architecture and belongs to the Alchemist (Arc 3) generation. Both are fabricated on a 6 nm process at TSMC, but the transistor density differs: 65.2M / mm² for AMD versus 45.9M / mm² for Intel.

The RDNA 3.0 design implements 1792 shading units, 112 texture mapping units, and 64 raster operations units. It includes 28 ray tracing cores. The Xe-HPG design implements 1024 shading units, 64 TMUs, and 32 ROPs, with 8 ray tracing cores. Neither card lists tensor cores or dedicated AI acceleration hardware.

The AMD architecture carries a larger transistor budget at 13,300 million versus 7,200 million, and a larger die at 204 mm² versus 157 mm². The RDNA 3.0 layout achieves higher density per square millimeter, indicating a more compact logic design for its feature set. The Intel die is smaller overall, but with fewer transistors per area.

Clock behavior also differs. The Radeon RX 7400 has a base clock of 1452 MHz, a game clock of 2200 MHz, and a boost clock of 2300 MHz. The Arc A380E runs at a fixed 2000 MHz for both base and boost, with no separate game clock listed. Memory clocks differ as well: the AMD card runs at 2250 MHz with 18 Gbps effective, while the Intel card runs at 1937 MHz with 15.5 Gbps effective.

The bus interface is identical: PCIe 4.0 x8 for both. API support matches across DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs diverge, with AMD offering a mix of HDMI 2.1a and DisplayPort 2.1, while Intel offers four DisplayPort 2.0 ports.

Specification Differences

The two cards differ on nearly every specification field in the database. The Radeon RX 7400 has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two cards, and the wins counter shows zero for each side. The Intel Arc A380E has no recorded benchmark scores at all, so no direct comparison of measured performance is possible from the recorded data.

The Radeon RX 7400's benchmark results provide an absolute reference. Its 3DMark Steel Nomad DX12 score is 1103. Passmark scores include 11897 for G3D, 5152 for GPU compute, 1209 for G2D, 176 for DirectX 9, 97 for DirectX 11, 59 for DirectX 10, and 44 for DirectX 12. The average benchmark score across all tests is 2467.

Nearest rivals for the Radeon RX 7400 include the AMD Radeon 8040S with an average score of 2440 (1.1% delta), the NVIDIA GeForce 710M at 2433 (1.4% delta), the Intel HD Graphics 610 at 2425 (1.8% delta), and the NVIDIA GeForce GT 710M at 2422 (1.9% delta). These deltas indicate the Radeon RX 7400 sits only marginally above a cluster of low-end integrated and entry-level discrete GPUs in aggregate scoring.

The Arc A380E has no rival data in the database, leaving its percentile of 50 as the only comparative signal. That percentile appears inconsistent with the absence of benchmark scores, suggesting the percentile derives from non-performance criteria or an incomplete dataset.

Given the massive gaps in FP32 throughput (16.49 TFLOPS vs 4.096 TFLOPS), texture rate (257.6 GTexel/s vs 128.0 GTexel/s), and bandwidth (288.0 GB/s vs 186.0 GB/s), the theoretical advantage sits firmly with the Radeon RX 7400. The Arc A380E's higher base clock (2000 MHz vs 1452 MHz) does not compensate for its smaller execution resource pool.

The Verdict

The data indicates a clear performance hierarchy. The AMD Radeon RX 7400 delivers four times the FP32 compute, double the texture rate, more than double the pixel rate, and over 50% more memory bandwidth compared to the Intel Arc A380E. It also carries more shading units, TMUs, ROPs, and ray tracing cores. For any workload that scales with these resources, the Radeon RX 7400 is the stronger choice.

The Intel Arc A380E offers structural advantages that matter in specific contexts. Its single-slot form factor and lack of external power connectors make it suitable for compact or constrained installations. Its four DisplayPort 2.0 outputs exceed the AMD card's three DisplayPort 2.1 ports plus one HDMI 2.1a, which may favor multi-display setups. Its 75 W TDP with no power connector requirement means simpler installation in systems with limited PSU headroom, though its suggested PSU of 250 W is higher than the AMD card's 200 W figure.

The Radeon RX 7400's 43 W TDP and 200 W suggested PSU indicate lower system power demand despite higher compute output. Its dual-slot design and 6-pin connector add physical installation requirements, but the performance gap is substantial.

The Arc A380E's end-of-life production status also matters. The database lists it as end-of-life, while the Radeon RX 7400 has no such designation and a later release date of 2025-08-07 versus 2024-03-31.

For users prioritizing measured or theoretical rendering performance, memory capacity, and bandwidth, the Radeon RX 7400 is the only viable option in this comparison. For users prioritizing minimal physical footprint, no external power cabling, or maximum DisplayPort output count, the Arc A380E offers specific advantages, but its performance ceiling is lower across every compute metric recorded. The absence of any benchmark scores for the Arc A380E means its real-world performance cannot be verified from the database, whereas the Radeon RX 7400 has eight recorded test results with an aggregate average of 2467.
