AMD Radeon 8040S vs Intel Arc A380E x2 Comparison

The Verdict

The database records two fundamentally different products. The AMD Radeon 8040S is an integrated graphics processor (IGP) built on the Strix Halo chip with a 55 W TDP, while the Intel Arc A380E x2 is a single-slot, 130 W discrete card with 6 GB of dedicated GDDR6 memory. The AMD part, despite being integrated, delivers a Passmark G3D score of 10,578, placing it in the 17th percentile of all GPUs. The Intel card has no recorded benchmark scores in the database, leaving its average benchmark score at 0, which makes a direct performance comparison impossible from the available data.

The AMD Radeon 8040S is the only one of the two with measured performance data. Its average benchmark score of 2,440 places it within 0.3% of the NVIDIA GeForce 710M and 0.6% of the Intel HD Graphics 610, while it sits 1.1% behind the AMD Radeon RX 7400. The Intel Arc A380E x2 has no rivals listed and no wins recorded. The data shows that for any user requiring measured performance figures, the AMD Radeon 8040S is the only option with verifiable results. The Intel card, with its end-of-life status and 300 W suggested power supply, targets a different deployment scenario, but the absence of benchmark data prevents any quantitative verdict in its favor.

Architecture Differences

The AMD Radeon 8040S uses the RDNA 3.5 architecture on a 4 nm TSMC process node, built into the Strix Halo chip with a die size of 308 mm². The Intel Arc A380E x2 uses the Xe-HPG architecture on a 6 nm TSMC process node, with the DG2-128 chip measuring 157 mm² and containing 7,200 million transistors. The transistor density for the Intel part is recorded at 45.9M per mm², while the AMD part lists its transistor count as unknown.

The AMD Radeon 8040S is an integrated part with no power connectors and a PCIe 5.0 x16 bus interface. The Intel Arc A380E x2 is a single-slot card measuring 265 mm in length, 127 mm in height, and 20 mm in width, requiring one 6-pin power connector and a 300 W suggested power supply. The Intel card uses a PCIe 4.0 x8 interface and provides 8x mini-DisplayPort 2.0 outputs, while the AMD part lists its display outputs as portable device dependent.

Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part implements 16 ray tracing cores, while the Intel part implements 8. Neither lists tensor cores. The AMD Radeon 8040S is based on the Navi Mobile (RX 8000M) generation with a predecessor of Polaris Mobile, while the Intel Arc A380E x2 belongs to the Alchemist (Arc 3) generation with a predecessor of Xe Graphics and a successor of Battlemage. The AMD part is marked as active in production, while the Intel part is marked as end-of-life.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database contains no entries, and neither product records any wins in this comparison. The AMD Radeon 8040S has seven individual Passmark benchmark scores, while the Intel Arc A380E x2 has none. This absence of overlapping data means the recorded measurements cannot establish a direct performance relationship between the two.

Looking at the AMD part alone, its Passmark scores show a distinct pattern. The DirectX 9 score of 134 is the highest among its DirectX tests, followed by DirectX 11 at 80, DirectX 10 at 48, and DirectX 12 at 47. The G2D score of 1,052 and the G3D score of 10,578 are far higher than the compute score of 5,138. These figures indicate the AMD part is substantially stronger in 3D rendering than in compute workloads, with the G3D score exceeding the compute score by roughly a factor of two.

The Intel Arc A380E x2 has no comparable measurements. Its average benchmark score of 0 and empty nearest rivals list mean the database contains no data points to set against the AMD part's scores. The only quantitative facts available for the Intel card are its specifications: a boost clock of 2000 MHz, 4.096 TFLOPS FP32, and 8.192 TFLOPS FP16. The AMD Radeon 8040S records a boost clock of 2800 MHz, 5.734 TFLOPS FP32, and 5.734 TFLOPS FP16. These figures show the AMD part has a higher FP32 throughput and a higher boost clock, while the Intel part has a 2:1 FP16 ratio that doubles its half-precision throughput.

Specification Differences

The two parts differ across nearly every recorded specification field. The process node differs: 4 nm for AMD versus 6 nm for Intel. The die size differs: 308 mm² for AMD versus 157 mm² for Intel. The Intel part lists 7,200 million transistors and a transistor density of 45.9M per mm², while the AMD part lists both as unknown or null.

The Intel Arc A380E x2 has a base clock of 2000 MHz and a boost clock of 2000 MHz, meaning no boost above base. Memory configurations are entirely different: the AMD part uses system shared memory with system dependent bandwidth, while the Intel part has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth and a memory clock of 1937 MHz (15.5 Gbps effective).

The compute resources are identical in shading units (1024), texture mapping units (64), and render output units (32). The ray tracing cores differ: 16 for AMD versus 8 for Intel.
