AMD Radeon RX 7800 XT vs Intel Arc A380E Comparison

Where Each One Wins

The AMD Radeon RX 7800 XT and Intel Arc A380E occupy entirely different performance tiers, and the recorded benchmark data confirms a decisive split. The RX 7800 XT is a high-throughput desktop GPU designed for demanding 1440p and 4K gaming workloads. The Arc A380E is an embedded-focused, low-power part aimed at industrial and commercial systems. The database shows no head-to-head benchmark entries between these two cards, and the Intel Arc A380E has no recorded benchmark scores at all. This absence of comparative data is itself informative: the two products are not direct competitors, and any use-case selection rests on their architectural positioning rather than measured performance parity.

The RX 7800 XT wins on every metric where data exists. It posts a 3DMark Steel Nomad DX12 score of 4157, a Geekbench OpenCL score of 18290, and a Geekbench Vulkan score of 54228. Its Passmark suite results are equally robust: 121 in DirectX 10, 249 in DirectX 11, 93 in DirectX 12, 304 in DirectX 9, 1177 in G2D, 24176 in G3D, and 13473 in GPU Compute. The Arc A380E has zero entries in the benchmark database, meaning its only measurable strengths are its physical footprint and power draw. The data indicates the RX 7800 XT is the only choice for compute-heavy or high-fidelity gaming workloads, while the Arc A380E is positioned for scenarios where minimal power consumption and a single-slot form factor are paramount.

Architecture Differences

The two GPUs share a common foundry but diverge on every major architectural decision. Both are fabricated by TSMC, but the RX 7800 XT uses a 5 nm process node while the Arc A380E uses 6 nm. The AMD chip, Navi 32, packs 28,100 million transistors into a 346 mm² die, yielding a transistor density of 81.2M per mm². The Intel chip, DG2-128, contains 7,200 million transistors on a 157 mm² die, with a density of 45.9M per mm². The RX 7800 XT is built on RDNA 3.0 architecture under the Wheat Nas codename, part of the Navi III generation. The Arc A380E uses Xe-HPG architecture from the Alchemist generation, also known as Arc 3.

The compute resources tell a clear story. The RX 7800 XT features 3840 shading units, 240 texture mapping units, 96 raster operations units, and 60 ray tracing cores. The Arc A380E offers 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The AMD card's pixel rate is 233.3 GPixel/s versus 64.00 GPixel/s for Intel. Texture rate is 583.2 GTexel/s versus 128.0 GTexel/s. FP32 throughput is 37.32 TFLOPS versus 4.096 TFLOPS. The RX 7800 XT delivers FP16 at a 1:1 ratio with FP32, while the Arc A380E achieves 8.192 TFLOPS FP16 at a 2:1 ratio. Memory configurations are equally divergent: 16 GB of GDDR6 on a 256-bit bus with 624.1 GB/s bandwidth for AMD, versus 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth for Intel.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7800 XT and the Arc A380E. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. This absence of comparative measurements means the analysis must rely on the individual benchmark suite recorded for the RX 7800 XT and the architectural specifications of the Arc A380E.

The RX 7800 XT's recorded scores establish a baseline for high-end performance. Its Geekbench Vulkan score of 54228 is nearly three times its OpenCL score of 18290, indicating strong Vulkan optimization. The Passmark G3D score of 24176 dwarfs the DirectX-specific results, with DirectX 9 at 304, DirectX 11 at 249, and DirectX 10 at 121. The DirectX 12 score of 93 is notably lower than the older API scores, which may reflect workload characteristics rather than raw capability. The GPU Compute score of 13473 and G2D score of 1177 round out the profile. The average benchmark score for the RX 7800 XT is 11627, placing it at the 51st percentile among all GPUs in the database.

The nearest rivals for the RX 7800 XT provide context for its positioning. The NVIDIA GeForce GTX 1660 averages 11680, which is 0.5% higher than the RX 7800 XT's average. The AMD Radeon Pro 5500M averages 11528, putting the RX 7800 XT 0.9% ahead. The NVIDIA Tesla K20c averages 11479, with the RX 7800 XT ahead by 1.3%. The AMD Radeon RX 6500 XT averages 11842, which is 1.8% above the RX 7800 XT. These delta percentages are small, indicating that the RX 7800 XT's average score sits in a tightly clustered performance band around the 51st percentile. The Arc A380E has no nearest rivals and a percentile rating of 50, but its average benchmark score is zero, reflecting the absence of recorded measurements.

The Verdict

The data directs different buyers to different products. The AMD Radeon RX 7800 XT is the clear choice for any workload requiring substantial graphics throughput. Its 37.32 TFLOPS FP32, 16 GB of memory, and 624.1 GB/s bandwidth support demanding gaming and compute applications. The 51st percentile ranking and average benchmark score of 11627 place it in a competitive band, with nearest rivals within a 1.8% range. The RX 7800 XT delivers 60 ray tracing cores, a 256-bit memory bus, and dual-slot cooling for sustained high-load operation.

The Intel Arc A380E is positioned for entirely different constraints. Its 75 W TDP, single-slot design, and lack of external power connectors make it suitable for embedded or space-constrained systems. The 6 GB memory capacity and 186.0 GB/s bandwidth are modest, and the 1024 shading units limit compute capability. The card is End-of-life production status, and it has no recorded benchmark scores in the database. The percentile rating of 50 suggests average positioning, but without measurement data, performance claims cannot be substantiated.

The recorded data shows no scenario where the Arc A380E outperforms the RX 7800 XT. The AMD card holds advantages in every architectural metric and every benchmark category. The Intel card's only advantages are its 75 W power draw, single-slot footprint, and 20 mm width, which are meaningful for specific industrial deployments but irrelevant for gaming or high-performance computing. The RX 7800 XT is the only option with demonstrated performance data, and its 51st percentile ranking confirms it as a mainstream-to-high-end part. The Arc A380E, with its zero benchmark scores and End-of-life status, is a niche product whose selection depends entirely on system constraints rather than performance expectations.
