AMD Radeon RX 7400 OEM vs Intel Arc A380E Comparison

Where Each One Wins

The recorded data for the AMD Radeon RX 7400 OEM and the Intel Arc A380E presents a case where neither card holds a definitive advantage in raw benchmark wins, as the head-to-head benchmark results are empty and both GPUs register zero wins each. This absence of direct comparative scores means the use-case split must be derived from the architectural and specification differences documented in the database rather than from performance measurements.

The AMD Radeon RX 7400 OEM positions itself as the stronger candidate for tasks that rely on raw shading throughput and memory capacity. Its shading units count 1792, which is 768 more than the Intel part, and it delivers 7.885 TFLOPS of FP32 compute. The memory subsystem holds 8 GB of GDDR6 on a 128-bit bus, producing 172.8 GB/s of bandwidth. These figures indicate a card oriented toward conventional rasterization workloads and applications that benefit from larger frame buffers.

The Intel Arc A380E, by contrast, shows a different set of strengths. Its FP16 compute rate of 8.192 TFLOPS exceeds its FP32 rate of 4.096 TFLOPS by a 2:1 ratio, a feature absent in the AMD card, which runs FP16 at a 1:1 ratio with FP32 at 7.885 TFLOPS. The Intel card's memory bandwidth is higher at 186.0 GB/s despite having only 6 GB of memory and a 96-bit bus, a result of its faster 15.5 Gbps effective memory clock versus the AMD card's 10.8 Gbps. The Intel card also supports four DisplayPort 2.0 outputs, while the AMD card provides one HDMI 2.1a and three DisplayPort 2.1 outputs.

The use-case split therefore centers on compute precision flexibility and display connectivity for the Intel Arc A380E, versus raw FP32 throughput, larger memory capacity, and higher pixel fill rate for the AMD Radeon RX 7400 OEM. The AMD card's pixel rate of 70.40 GPixel/s outpaces the Intel card's 64.00 GPixel/s, suggesting an edge in fill-rate-bound scenarios. The Intel card's texture rate of 128.0 GTexel/s slightly exceeds the AMD card's 123.2 GTexel/s, indicating a marginal advantage in texture-heavy workloads.

Architecture Differences

The architectural designs of these two GPUs reflect fundamentally different approaches from their respective manufacturers.

The AMD Radeon RX 7400 OEM is built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III generation within the Radeon RX 7000 series. Its predecessor is Navi II and its successor is Navi IV. The architecture uses a chiplet-like design philosophy typical of the RDNA 3 generation, though the database does not specify chiplet details for this particular card.

The Intel Arc A380E is built on Xe-HPG architecture and belongs to the Alchemist generation, specifically Arc 3. Its predecessor is Xe Graphics and its successor is Battlemage. The Xe-HPG architecture is Intel's high-performance graphics design, and the DG2-128 chip represents the smaller die in the Alchemist lineup.

The compute architecture differs in how FP16 throughput is handled. The AMD card runs FP16 at a 1:1 ratio with FP32, meaning both rates are 7.885 TFLOPS. The Intel card runs FP16 at a 2:1 ratio, doubling its FP32 rate of 4.096 TFLOPS to 8.192 TFLOPS for FP16. This indicates the Intel architecture has dedicated FP16 execution pathways that the AMD card does not expose in the same manner.

Ray tracing hardware differs substantially. The AMD card contains 28 ray tracing cores, while the Intel card contains only 8. This represents a 20-core difference in dedicated ray tracing hardware, suggesting the AMD architecture allocates more silicon to this feature.

The transistor density provides insight into design efficiency. The AMD card achieves 65.2 million transistors per square millimeter, while the Intel card achieves 45.9 million per square millimeter. Both use the same 6 nm TSMC process, so the density difference reflects design choices in logic complexity and cache structures rather than manufacturing differences.

The bus interfaces are identical at PCIe 4.0 x8 for both cards. The API support is also identical across DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates that the AMD Radeon RX 7400 OEM and the Intel Arc A380E serve different priorities, and the choice between them depends on which specifications matter most for a given workload.

The AMD Radeon RX 7400 OEM shows a clear advantage in raw FP32 compute, delivering 7.885 TFLOPS versus the Intel card's 4.096 TFLOPS. Its larger memory capacity of 8 GB versus 6 GB, higher shading unit count of 1792 versus 1024, and greater pixel rate of 70.40 GPixel/s versus 64.00 GPixel/s all point toward stronger performance in conventional 3D rendering and gaming workloads. The higher transistor count of 13,300 million versus 7,200 million reinforces this position. The AMD card also has more ray tracing cores at 28 versus 8, which may benefit ray-traced effects in supported titles.

The Intel Arc A380E counters with a higher boost clock of 2000 MHz versus 1100 MHz, higher memory bandwidth of 186.0 GB/s versus 172.8 GB/s, and superior FP16 throughput of 8.192 TFLOPS versus 7.885 TFLOPS. Its higher texture rate of 128.0 GTexel/s versus 123.2 GTexel/s gives it a slight edge in texture-bound operations. The card requires no external power connectors despite a higher TDP of 75 W versus 55 W, which may simplify installation in constrained systems. Its four DisplayPort 2.0 outputs offer more display connectivity options than the AMD card's one HDMI and three DisplayPort 2.1 outputs.

The Intel card is marked as end-of-life in the database, while the AMD card has no recorded production status and a later release date of 2025-08-07 versus 2024-03-31. This suggests the AMD card is the more current product.

The database shows both cards at the 50th percentile among all GPUs, indicating they occupy similar overall performance tiers. Without direct head-to-head benchmark scores, the specification analysis suggests the AMD card is the stronger choice for compute-heavy and memory-intensive tasks, while the Intel card offers advantages in clock speed, FP16 throughput, and display output flexibility.
