AMD Radeon RX 7800 XT vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison situation. The AMD Radeon RX 7800 XT has a complete set of benchmark scores across multiple test suites, while the Intel Arc A380E x2 has no entries in the benchmark database. This means there are no direct head-to-head measurements where both cards were run under identical conditions in the same test.

The AMD Radeon RX 7800 XT's avgBenchmarkScore is 11627, placing it at the 51st percentile among all GPUs in the database. Its nearest rivals in the database include the NVIDIA GeForce GTX 1660 with an average score of 11680, which is 0.5% higher, and the AMD Radeon RX 6500 XT with an average score of 11842, which is 1.8% higher. The AMD Radeon Pro 5500M trails by 0.9% with a score of 11528, and the NVIDIA Tesla K20c trails by 1.3% with a score of 11479.

Looking at the individual benchmark results for the AMD card, the strongest performance appears in the Geekbench Vulkan test with a score of 54228, followed by Geekbench OpenCL at 18290. The Passmark G3D score reaches 24176, while Passmark GPU Compute reaches 13473. The DirectX 9 test scores 304, DirectX 11 scores 249, and DirectX 10 scores 121. The DirectX 12 result is 93, and the 3DMark Steel Nomad DX12 test produces a score of 4157. The Passmark G2D score is 1177.

For the Intel Arc A380E x2, the database shows an avgBenchmarkScore of 0 and a percentileVsAllGpus of 50, but no benchmark entries exist. The winsA and winsB fields both show 0, confirming that no head-to-head tests were recorded between these two products. The comparison therefore rests entirely on the AMD card's measured results and the architectural and specification differences documented in the database.

The absence of benchmark data for the Intel card means its performance cannot be quantified relative to the AMD card in any test. The AMD card's scores can be contextualized against its nearest rivals, but no such comparison exists for the Intel product. Readers should interpret the AMD card's percentile of 51 as indicating it sits near the median of all GPUs in the database, with its average score of 11627 falling within a narrow band around the 11680 score of the GTX 1660.

Architecture Differences

The two cards come from different manufacturers and use fundamentally different architectures. The AMD Radeon RX 7800 XT uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas, and belongs to the Navi III (RX 7000) generation. The Intel Arc A380E x2 uses the DG2-128 chip built on Xe-HPG architecture and belongs to the Alchemist (Arc 3) generation.

The manufacturing process differs significantly. The AMD card is fabricated on a 5 nm process at TSMC, while the Intel card uses a 6 nm process, also at TSMC. The transistor counts show a substantial gap: the AMD chip contains 28,100 million transistors on a die size of 346 mm², resulting in a transistor density of 81.2M per mm². The Intel chip contains 7,200 million transistors on a die size of 157 mm², giving a transistor density of 45.9M per mm². The AMD chip is roughly four times larger in both transistor count and die area.

The streaming multiprocessor configuration differs across every major unit. The AMD card has 3840 shading units, 240 texture mapping units, 96 render output units, and 60 ray tracing cores. The Intel card has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The AMD card therefore has 3.75 times more shading units, 3.75 times more TMUs, 3 times more ROPs, and 7.5 times more ray tracing cores.

Clock speeds follow a different pattern. The AMD card has a base clock of 1295 MHz and a boost clock of 2430 MHz, with a game clock of 2124 MHz. The Intel card has a base clock of 2000 MHz and a boost clock of 2000 MHz, meaning its clocks are fixed with no boost headroom. The memory clock for the AMD card is 2438 MHz with 19.5 Gbps effective, while the Intel card runs at 1937 MHz with 15.5 Gbps effective.
