AMD Radeon 780M vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 780M and Intel Arc A380E does not include any direct head-to-head benchmark results. The head-to-head benchmark array is empty, and the win counters for both parts are zero. However, the broader database contains standalone measurements for the Radeon 780M across three tests, while the Arc A380E has no recorded benchmark scores at all. This absence of comparable test data means a traditional side-by-side performance comparison cannot be constructed from the available records.

The Radeon 780M delivers a 3DMark Steel Nomad DX12 score of 480, a Geekbench OpenCL score of 18,602, and a Geekbench Vulkan score of 33,683. Its average benchmark score across these three runs is 17,588, which places it at the 61st percentile among all GPUs in the database. The Arc A380E, by contrast, has an average benchmark score of zero and sits at the 50th percentile, with no individual test scores recorded. The database shows a 0.2% advantage for the Radeon 780M over the AMD Radeon Pro 560, which averages 17,551. Against the NVIDIA GeForce RTX 4060, the Radeon 780M trails by 0.3%, with the RTX 4060 scoring 17,639. The AMD Radeon HD 7790 leads the Radeon 780M by 0.4% with an average of 17,666, while the Radeon Pro 460 sits 0.5% behind at 17,509.

These nearest-rival comparisons indicate that the Radeon 780M clusters tightly with a set of mid-range desktop and mobile GPUs, all within a 0.9% band. The performance spread is minimal, which suggests that the 780M's integrated design achieves parity with several discrete GPUs from earlier generations. The Arc A380E has no rival data in the database, so its relative standing cannot be assessed numerically. The data confirms that the Radeon 780M is a measured, quantifiable performer, while the Arc A380E lacks any benchmark footprint in the current records.

The Verdict

Based strictly on the database records, the AMD Radeon 780M is the only one of these two GPUs with measurable performance data. Its average benchmark score of 17,588 and 61st percentile ranking establish it as a functional, competitive part in the database's distribution. The Intel Arc A380E has no benchmark scores, no rivals, and an average score of zero, so it cannot be positioned against the Radeon 780M or any other GPU in a quantitative manner.

For scenarios where a benchmark score is required, the Radeon 780M is the clear choice, as it delivers a 3DMark Steel Nomad DX12 score of 480, a Geekbench OpenCL score of 18,602, and a Geekbench Vulkan score of 33,683. The Arc A380E offers no comparable data points. In terms of compute throughput, the Radeon 780M's FP32 figure of 8.909 TFLOPS exceeds the Arc A380E's 4.096 TFLOPS, and its FP16 figure of 8.909 TFLOPS (1:1) matches the Arc A380E's 8.192 TFLOPS (2:1) but with a different ratio. The Radeon 780M also carries twice the transistor count at 25,390 million versus 7,200 million, and a smaller process node at 4 nm versus 6 nm.

The Arc A380E does hold advantages in memory and board design. It has a fixed 6 GB GDDR6 memory pool with 186.0 GB/s of bandwidth, whereas the Radeon 780M relies on system-shared memory with system-dependent bandwidth. The Arc A380E is a single-slot card with four DisplayPort 2.0 outputs and a 254 mm length, while the Radeon 780M is an integrated GPU (IGP) with motherboard-dependent outputs. The Arc A380E has a 75 W TDP and a 250 W suggested PSU, while the Radeon 780M has a 15 W TDP and no power connectors. For users who need a standalone, low-profile discrete card with dedicated memory, the Arc A380E offers a physical form factor and memory configuration that the IGP cannot match. For any performance metric derived from benchmarks, the Radeon 780M is the only option with recorded evidence.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Radeon 780M uses a 4 nm process node, while the Arc A380E uses a 6 nm node, both fabricated by TSMC. Transistor counts differ substantially: the Radeon 780M contains 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6 million per mm². The Arc A380E contains 7,200 million transistors on a 157 mm² die, with a density of 45.9 million per mm².

Clock speeds diverge as well. The Radeon 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The Arc A380E runs at a flat 2000 MHz for both base and boost. Memory configurations are entirely different: the Radeon 780M uses system-shared memory with system-shared type, bus width, and system-dependent bandwidth. The Arc A380E uses 6 GB of GDDR6 memory on a 96-bit bus with 186.0 GB/s of bandwidth and a memory clock of 1937 MHz (15.5 Gbps effective).

Compute resources differ in count and throughput. The Radeon 780M has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Pixel rates are 92.80 GPixel/s for the Radeon 780M versus 64.00 GPixel/s for the Arc A380E. Texture rates are 139.2 GTexel/s versus 128.0 GTexel/s. FP32 compute is 8.909 TFLOPS for the Radeon 780M and 4.096 TFLOPS for the Arc A380E. FP16 compute is 8.909 TFLOPS (1:1) for the Radeon 780M and 8.192 TFLOPS (2:1) for the Arc A380E.

Power and physical specifications also differ. The Radeon 780M has a 15 W TDP, is an IGP with no power connectors, and has no suggested PSU. The Arc A380E has a 75 W TDP, is single-slot with no power connectors, and lists a 250 W suggested PSU. The Radeon 780M has no recorded dimensions, while the Arc A380E measures 254 mm in length, 127 mm in height, and 20 mm in width. Display outputs are motherboard dependent for the Radeon 780M, while the Arc A380E provides four DisplayPort 2.0 outputs. Both use a PCIe 4.0 x8 bus interface. The Radeon 780M is marked as Active in production status, while the Arc A380E is End-of-life.

Architecture Differences

The Radeon 780M is built on the RDNA 3.0 architecture, part of the Navi III IGP (Phoenix) generation, using the Phoenix chip. The Arc A380E is built on the Xe-HPG architecture, part of the Alchemist (Arc 3) generation, using the DG2-128 chip. These are fundamentally different GPU architectures from different manufacturers, with different design philosophies reflected in their compute and memory configurations.

The RDNA 3.0 architecture in the Radeon 780M emphasizes a 1:1 FP16 to FP32 ratio, meaning both FP16 and FP32 throughput are rated at 8.909 TFLOPS. This indicates a design where half-precision and single-precision operations share the same hardware path without dedicated acceleration for FP16. The Xe-HPG architecture in the Arc A380E uses a 2:1 ratio, where FP16 throughput of 8.192 TFLOPS is exactly double the FP32 throughput of 4.096 TFLOPS. This suggests the Arc A380E has dedicated hardware for half-precision operations, a common feature for AI and compute workloads that benefit from FP16.

Ray tracing hardware also differs. The Radeon 780M includes 12 ray tracing cores, while the Arc A380E includes 8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature sets are identical. The Radeon 780M has no tensor cores listed, and neither does the Arc A380E, so neither GPU appears to have dedicated tensor or matrix acceleration in the recorded data.

The transistor density difference is stark: the Radeon 780M packs 142.6 million transistors per mm² versus 45.9 million per mm² for the Arc A380E. This reflects the 4 nm versus 6 nm process difference and the larger transistor budget of the Radeon 780M. The Radeon 780M's predecessor is listed as Navi II IGP and its successor as Navi III IGP, while the Arc A380E's predecessor is Xe Graphics and its successor is Battlemage. The Radeon 780M was released on 2024-01-30, and the Arc A380E on 2024-03-31. The Radeon 780M remains Active, while the Arc A380E is End-of-life, which may influence long-term driver support and availability in the database's context.
