AMD Radeon 680M vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded data for these two GPUs presents an unusual comparison problem: the AMD Radeon 680M has a full set of benchmark results, while the Intel Arc A380E has no recorded scores in the database. This asymmetry means the head-to-head section relies entirely on the AMD side's measured performance and the architectural specifications of both parts.

The AMD Radeon 680M posts an average benchmark score of 15,270 across its three recorded tests. Its strongest result comes from Geekbench OpenCL, where it scores 23,468, followed closely by Geekbench Vulkan at 21,965. The 3DMark Steel Nomad DX12 test shows a much lower score of 378, reflecting the lighter workload class of that test rather than a weakness in the GPU itself. The average score places the 680M at the 57th percentile among all GPUs in the database.

The nearest rivals for the 680M show how tightly clustered its performance is. The NVIDIA GeForce RTX 2060 sits at an average score of 15,290, which is 0.1% ahead of the 680M. The NVIDIA GeForce GTX 580 matches almost exactly at 15,283, also 0.1% ahead. The NVIDIA GeForce RTX 3050 OEM trails slightly at 15,199, putting the 680M 0.5% ahead of that card. The AMD Radeon RX 7600 scores 15,171, meaning the 680M holds a 0.7% advantage. These deltas are tiny, all within one percentage point, indicating that the integrated 680M performs in the same league as several discrete desktop graphics cards from previous generations.

The Intel Arc A380E has no benchmarks recorded in the database. Its average score is listed as zero, and there are no nearest rivals to compare against. This does not indicate a lack of capability, only that the database has not captured measurement data for this SKU. The head-to-head comparison must therefore be framed around what the architecture and specifications suggest, rather than direct measured scores.

The FP32 throughput figures offer one numerical comparison point. The Arc A380E delivers 4.096 TFLOPS, which is 21.2% higher than the 680M's 3.379 TFLOPS. Texture rate follows a similar pattern: the A380E reaches 128.0 GTexel/s against 105.6 GTexel/s for the 680M, a 21.2% advantage. Pixel rate, however, favors AMD: the 680M produces 70.40 GPixel/s versus 64.00 GPixel/s for the A380E, an advantage of 10% for the AMD part.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon 680M uses the RDNA 2.0 architecture, built on the Rembrandt+ chip, and belongs to the Navi II IGP generation for Rembrandt Mobile. The Intel Arc A380E uses the Xe-HPG architecture, built on the DG2-128 chip, and sits in the Alchemist (Arc 3) generation. Both are fabricated by TSMC on a 6 nm process node, so process technology is not a differentiator.

The transistor budgets differ substantially. The AMD chip contains 13,100 million transistors on a 208 mm² die, giving a transistor density of 63.0 million per square millimeter. The Intel chip packs 7,200 million transistors onto a 157 mm² die, resulting in a lower density of 45.9 million per square millimeter. The AMD die is larger in both total transistor count and physical area, and it achieves a higher packing density.

Core configuration also differs. The 680M carries 768 shading units, 48 texture mapping units, and 32 ROPs. The A380E has 1,024 shading units, 64 TMUs, and 32 ROPs. Intel leads in shader count by 33% and in TMU count by 33%, while both parts have identical ROP counts at 32. Ray tracing hardware is present on both, but with different counts: the 680M has 12 ray tracing cores, while the A380E has 8. Neither GPU lists tensor cores in the database.

Clock behavior separates the two parts clearly. The 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz, allowing dynamic frequency increase under load. The A380E runs at a flat 2000 MHz for both base and boost, with no headroom above its base frequency. Memory architecture is fundamentally different. The 680M uses system shared memory, with bandwidth listed as system dependent and no dedicated VRAM. The A380E brings 6 GB of GDDR6 on a 96-bit bus, with a fixed bandwidth of 186.0 GB/s and a memory clock of 1937 MHz (15.5 Gbps effective).

Form factor and power delivery differ as well. The 680M is an integrated GPU with no slot width, no power connectors, and a 50 W TDP. The A380E is a single-slot discrete card measuring 254 mm in length, 127 mm in height, and 20 mm in width. It also draws no power connectors but has a higher 75 W TDP and a suggested PSU rating of 250 W. The A380E offers four DisplayPort 2.0 outputs, while the 680M's display outputs depend on the portable device it is integrated into.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels match. The bus interface is PCIe 4.0 x8 for both. Production status differs: the 680M is listed as active, while the A380E is end-of-life. The release dates also differ, with the 680M launching on January 2, 2023, and the A380E on March 31, 2024.

The two GPUs share several specifications as well. Both use PCIe 4.0 x8, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, both are on a 6 nm TSMC process, and both have 32 ROPs. Neither has a launch MSRP listed in the database.

Where Each One Wins

The AMD Radeon 680M wins in areas tied to its integrated nature and certain throughput metrics. Its pixel rate of 70.40 GPixel/s beats the A380E's 64.00 GPixel/s by 10%, which can benefit fill-rate-bound workloads. The 680M also has 12 ray tracing cores versus 8 for the A380E, giving it a structural advantage in ray-traced scenes if driver and software support keep pace. The boost clock of 2200 MHz provides dynamic frequency scaling above its 2000 MHz base, whereas the A380E is locked at 2000 MHz with no boost headroom. The 680M's lower TDP of 50 W against 75 W means it fits into power-constrained portable designs, and its active production status indicates continued availability. The measured benchmark data shows the 680M performing at the 57th percentile of all GPUs, with an average score of 15,270, placing it within 0.1% of the GeForce RTX 2060 and GTX 580 and ahead of the RTX 3050 OEM and RX 7600.

The Intel Arc A380E wins on raw compute throughput and dedicated memory resources. Its FP32 performance of 4.096 TFLOPS is 21.2% higher than the 680M's 3.379 TFLOPS, and its texture rate of 128.0 GTexel/s beats 105.6 GTexel/s by the same margin. The 6 GB of GDDR6 with 186.0 GB/s of bandwidth provides a fixed, predictable memory subsystem, unlike the 680M's system-dependent shared memory. The A380E has 1,024 shading units and 64 TMUs, both 33% higher than the 680M's 768 and 48 respectively. Its single-slot discrete form factor with four DisplayPort 2.0 outputs makes it suitable for multi-display configurations, and the suggested PSU of 250 W quantifies system power requirements explicitly. The flat 2000 MHz clock across base and boost suggests consistent performance without thermal or power-driven frequency variation.

The use-case split follows the hardware profile. The 680M suits integrated, low-power mobile platforms where the 50 W TDP, system shared memory, and portable-device-dependent outputs are acceptable trade-offs. Its higher pixel rate and more numerous ray tracing cores give it an edge in specific rendering workloads. The A380E targets discrete, multi-display desktop setups where dedicated GDDR6 memory, higher shader throughput, and fixed display outputs matter more. The absence of benchmark data for the A380E means its actual measured performance cannot be verified against the 680M, but the specification sheet points to a GPU built for sustained compute throughput rather than integrated efficiency.
