Architecture Differences

The AMD Radeon RX 7400 OEM and Intel Arc A310E represent two distinct approaches to low-power discrete graphics. AMD's chip, codenamed Hotpink Bonefish, is part of the Navi III (RX 7000) generation and uses RDNA 3.0 architecture. Intel's chip, DG2-128, belongs to the Alchemist (Arc 3) generation and uses Xe-HPG architecture. Both rely on TSMC's 6 nm process, but the transistor budgets differ sharply. AMD packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2M per mm². Intel fits 7,200 million transistors into a 157 mm² die, for a density of 45.9M per mm².

The compute resources diverge significantly. The Radeon RX 7400 OEM carries 1,792 shading units, 112 texture mapping units, 64 raster operation units, and 28 ray tracing cores. The Arc A310E has 768 shading units, 32 TMUs, 16 ROPs, and 6 ray tracing cores. This gives AMD a 2.33x advantage in shading units, a 3.5x advantage in TMUs, and a 4x advantage in ROPs. The ray tracing core count favors AMD by a factor of 4.67x.

FP32 throughput tells a similar story. The AMD card delivers 7.885 TFLOPS, while the Intel card delivers 3.072 TFLOPS. In FP16, AMD maintains 7.885 TFLOPS with a 1:1 ratio, while Intel reaches 6.144 TFLOPS with a 2:1 ratio. Intel's FP16 advantage over its own FP32 shows the Xe-HPG architecture's dual-rate execution, but the absolute FP16 number still trails AMD's.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity holds. The PCIe interface is identical at PCIe 4.0 x8. Physical dimensions are close: AMD measures 167 mm (6.6 inches) in length, while Intel measures 168 mm (6.6 inches) with a height of 69 mm (2.7 inches) and width of 20 mm (0.8 inches). Both are single-slot cards.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores for these two cards. There are no recorded benchmark wins for either product in the matchup data, and both cards hold a 50th percentile position relative to all GPUs in the database. The average benchmark score for each is listed as zero, which limits the ability to compare measured performance directly.

However, the architectural specifications allow for a clear theoretical comparison. The Radeon RX 7400 OEM's pixel rate of 70.40 GPixel/s is 2.2x higher than the Arc A310E's 32.00 GPixel/s. The texture rate shows an even larger gap: 123.2 GTexel/s versus 64.00 GTexel/s, a 1.93x advantage for AMD. The FP32 compute difference of 7.885 TFLOPS versus 3.072 TFLOPS represents a 2.57x lead for the Radeon.

Memory bandwidth favors AMD at 172.8 GB/s versus 124.0 GB/s, a 1.39x advantage. The 8 GB frame buffer versus 4 GB also gives AMD a substantial capacity lead for modern workloads. The Intel card counters with higher clocks: a 2000 MHz boost versus AMD's 1100 MHz boost, and faster effective memory at 15.5 Gbps versus 10.8 Gbps. These clock advantages cannot close the gap created by AMD's larger execution resource pool.

Ray tracing hardware also favors AMD decisively. With 28 ray tracing cores versus Intel's 6, the Radeon has a 4.67x advantage in dedicated RT hardware. The Intel card's FP16 throughput of 6.144 TFLOPS is its closest relative strength to AMD's 7.885 TFLOPS, but it still trails by roughly 22%.

The Verdict

The recorded data indicates a clear performance hierarchy. The AMD Radeon RX 7400 OEM holds a decisive specification advantage in nearly every compute metric. Its 7.885 TFLOPS FP32 output is 2.57x the Arc A310E's 3.072 TFLOPS. Its 8 GB memory capacity is double Intel's 4 GB, and its 172.8 GB/s bandwidth is 39% higher. The Radeon also leads in pixel rate, texture rate, and ray tracing core count.

The Intel Arc A310E is not without its own strengths. It runs at a 2000 MHz boost clock, nearly double the AMD card's 1100 MHz boost. It also requires no external power connector despite a 75 W TDP, which is actually higher than the AMD card's 55 W TDP. The Intel card's 4x mini-DisplayPort 2.0 outputs may suit multi-display configurations. Its end-of-life status, however, signals limited forward availability.

For raw compute and memory capacity, the Radeon RX 7400 OEM is the stronger product on paper. The Intel Arc A310E appears positioned for compact, low-connectivity deployments where its lack of a power connector and small physical footprint are advantages. The 50th percentile ranking for both cards in the database suggests they occupy similar overall performance tiers, but the specification deltas point to AMD having more headroom.

Where Each One Wins

AMD Radeon RX 7400 OEM wins on raw compute. The 7.885 TFLOPS FP32 figure is more than double Intel's 3.072 TFLOPS. The 123.2 GTexel/s texture rate and 70.40 GPixel/s pixel rate make it the stronger choice for texture-heavy and fill-rate-bound workloads.

AMD Radeon RX 7400 OEM wins on memory capacity and bandwidth. The 8 GB frame buffer handles larger assets and higher resolutions than the 4 GB Arc A310E. The 172.8 GB/s bandwidth versus 124.0 GB/s reduces the likelihood of memory-bound stalls.

AMD Radeon RX 7400 OEM wins on ray tracing. With 28 RT cores versus 6, the Radeon has substantially more dedicated hardware for ray-traced effects.

Intel Arc A310E wins on clock speed. The 2000 MHz base and boost clocks are far above AMD's 330 MHz base and 1100 MHz boost. This may translate to better responsiveness in latency-sensitive scenarios.

Intel Arc A310E wins on power connector flexibility. The card requires no external power connector, simplifying installation in systems with limited PSU cabling.

Intel Arc A310E wins on display output count. Four mini-DisplayPort 2.0 outputs exceed AMD's three DisplayPort 2.1 outputs plus one HDMI 2.1a, assuming the user can adapt mini-DisplayPort connections.

Intel Arc A310E wins on FP16 efficiency. The 6.144 TFLOPS FP16 rate, achieved with a 2:1 ratio, narrows the gap to AMD's 7.885 TFLOPS in workloads that use reduced precision.
