AMD Radeon 8040S vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the Intel Arc A380E has no benchmark entries in the database, while the AMD Radeon 8040S has a full set of PassMark results. The AMD part posts a PassMark G3D score of 10578, which places it at the 17th percentile among all GPUs. Its average benchmark score across all tests is 2440. The Intel Arc A380E shows no recorded scores, no average, and no rival comparisons, meaning the database cannot produce direct head-to-head deltas between the two.

The AMD Radeon 8040S demonstrates its strongest result in the PassMark DirectX 9 test with a score of 134, which is roughly 2.8 times higher than its DirectX 10 score of 48 and about 2.9 times higher than its DirectX 12 score of 47. The DirectX 11 score of 80 sits between those extremes. This pattern suggests the RDNA 3.5 architecture in the 8040S handles legacy DirectX 9 workloads particularly well relative to its newer API performance. The compute score of 5138 is substantial, representing nearly half of the G3D score, which indicates strong general-purpose GPU compute capability for a mobile integrated part.

The 2D graphics score of 1052 is notably high compared to the 3D score, a characteristic often seen in integrated GPUs where desktop composition and 2D acceleration are prioritized. The texture rate of 179.2 GTexel/s and pixel rate of 89.60 GPixel/s are derived from the 64 texture mapping units and 32 raster operation units operating at a boost clock of 2800 MHz. The FP32 throughput of 5.734 TFLOPS matches the FP16 throughput exactly at a 1:1 ratio, which differs from the Intel part's 2:1 FP16 ratio. The AMD GPU's nearest rivals in the database include the NVIDIA GeForce 710M with an average score of 2433 and a delta of 0.3%, the Intel HD Graphics 610 at 2425 with a 0.6% delta, and the NVIDIA GeForce GT 710M at 2422 with a 0.7% delta. The AMD Radeon RX 7400 sits above it with a score of 2467 and a delta of -1.1%, meaning the 8040S trails that discrete card by roughly 1.1% in average score.

The Verdict

The database shows that the AMD Radeon 8040S has measurable performance data across seven benchmark tests, while the Intel Arc A380E has none. This makes a direct performance verdict impossible from recorded measurements. What the data does show is that the 8040S occupies the 17th percentile of all GPUs, a low position that indicates it performs below the vast majority of graphics hardware in the database. Its average benchmark score of 2440 places it within a tight cluster of older entry-level discrete and integrated parts, all within 1.1% of each other.

The Intel Arc A380E, by contrast, holds the 50th percentile ranking despite having no benchmark scores. This percentile is a database classification, not a measured result, and the absence of an average score means it cannot be compared numerically to the AMD part. The A380E is marked as end-of-life production status, while the 8040S is active. For anyone choosing between these two strictly on available data, the AMD part has verifiable performance numbers, whereas the Intel part's actual performance is unrecorded in this database. The 8040S is also a newer release, dated January 5, 2025, compared to the A380E's March 31, 2024 date.

The power characteristics differ meaningfully. The 8040S carries a 55 W TDP and is an integrated GPU with no power connectors and a slot width of IGP. The A380E has a 75 W TDP, is a single-slot discrete card with no power connectors, and includes a suggested PSU rating of 250 W. The A380E also has physical dimensions of 254 mm in length, 127 mm in height, and 20 mm in width, while the 8040S has no recorded dimensions because it is designed to be integrated into a portable device.

Where Each One Wins

The AMD Radeon 8040S wins in every category where the database has recorded measurements, simply because the Intel Arc A380E has no benchmark entries. The 8040S delivers a PassMark G3D score of 10578, a compute score of 5138, and a 2D score of 1052. Its DirectX 9 score of 134 is its highest API-specific result, suggesting legacy game compatibility is a relative strength. The DirectX 11 score of 80 is the second highest, followed by DirectX 10 at 48 and DirectX 12 at 47, indicating a regression with newer API versions that is uncommon but measurable.

The Intel Arc A380E wins in the categories of physical specifications and memory configuration. It offers 6 GB of dedicated GDDR6 memory on a 96-bit bus with 186.0 GB/s of bandwidth, whereas the 8040S relies on system shared memory with bandwidth described as system dependent. The A380E's memory clock is 1937 MHz with 15.5 Gbps effective data rate, a concrete figure compared to the 8040S's shared memory setup. The A380E also has a higher base and boost clock of 2000 MHz, though this is a specification difference rather than a measured performance advantage.

In terms of compute throughput, the 8040S delivers 5.734 TFLOPS FP32, which is about 40% higher than the A380E's 4.096 TFLOPS. However, the A380E delivers 8.192 TFLOPS FP16 at a 2:1 ratio, which is about 43% higher than the 8040S's FP16 output of 5.734 TFLOPS at a 1:1 ratio. This means the AMD part is stronger for FP32 workloads, while the Intel part is stronger for FP16 workloads if the application can use the reduced precision.

The 8040S has 16 ray tracing cores compared to the A380E's 8, though neither has tensor cores recorded. Both GPUs have identical shading unit counts of 1024, identical TMU counts of 64, and identical ROP counts of 32. The AMD part has a higher pixel rate of 89.60 GPixel/s versus 64.00 GPixel/s for Intel, and a higher texture rate of 179.2 GTexel/s versus 128.0 GTexel/s.
