Architecture Differences

The Intel Arc A770M and AMD Radeon R9 M380 represent two vastly different eras of mobile graphics design. The Arc A770M uses Intel's Xe-HPG architecture, built on a 6 nm process at TSMC, while the R9 M380 uses AMD's GCN 2.0 architecture on a 28 nm process, also at TSMC. The manufacturing gap is substantial: the Arc A770M packs 21,700 million transistors into a 406 mm² die, yielding a transistor density of 53.4 million per square millimeter. The R9 M380 contains just 2,080 million transistors on a 160 mm² die, with a density of 13.0 million per square millimeter.

The compute resources diverge sharply. The Arc A770M has 4,096 shading units, 256 texture mapping units, and 128 ROPs. It also includes 32 ray tracing cores, a feature entirely absent from the R9 M380. The AMD part offers 768 shading units, 48 TMUs, and only 16 ROPs. These differences translate directly into pixel and texture throughput: the Arc A770M delivers 262.4 GPixel/s and 524.8 GTexel/s, while the R9 M380 manages 16.00 GPixel/s and 48.00 GTexel/s.

Memory architecture also separates the two. The Arc A770M uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The R9 M380 uses 4 GB of GDDR5 on a 128-bit bus, with 96.00 GB/s. Clock speeds reflect the process advantage: the Intel GPU runs at 1650 MHz base and 2050 MHz boost, while the AMD part runs at 900 MHz base and 1000 MHz boost. Memory clocks differ as well, with 16 Gbps effective for Intel versus 6 Gbps effective for AMD.

API support shows the generational gap. The Arc A770M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The R9 M380 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The bus interface also differs: PCIe 4.0 x16 for Intel versus PCIe 3.0 x16 for AMD.

Where Each One Wins

The Intel Arc A770M wins decisively in the single shared benchmark, Geekbench OpenCL, with a 612.2% advantage. That result, combined with its modern compute resources, makes it the clear choice for compute-heavy workloads such as OpenCL acceleration, machine learning inference, and content creation tasks that leverage the GPU for general-purpose processing.

The Arc A770M also stands out for its ray tracing capabilities. With 32 dedicated ray tracing cores, it can handle hardware-accelerated ray tracing in supported DirectX 12 Ultimate titles. The R9 M380 has no such capability, meaning it relies entirely on software-based or approximate techniques.

The R9 M380, however, has its own niche. Its average benchmark score of 15,521 places it near the NVIDIA GeForce GTX 1080 Ti (0.2% behind) and the AMD Radeon Pro W5500 (1.0% behind). This suggests it remains competitive for its era, particularly for older DirectX 11 or early DirectX 12 titles that do not demand modern feature sets. Its lower memory footprint of 4 GB may suit lighter workloads, and its GCN 2.0 architecture has broad legacy driver support.

For gaming, the Arc A770M's higher pixel rate (262.4 GPixel/s) and texture rate (524.8 GTexel/s) indicate a significant advantage in fill-rate-bound scenarios. The R9 M380's 16.00 GPixel/s and 48.00 GTexel/s are orders of magnitude lower, which would limit performance in high-resolution or high-detail settings. The Intel part's 16 GB memory capacity also allows for larger texture sets and higher resolutions without hitting memory limits.

Head-to-Head Benchmarks

The database contains one shared benchmark between these two GPUs: Geekbench OpenCL. The Intel Arc A770M scores 89,494, while the AMD Radeon R9 M380 scores 12,565. The delta is 612.2%, meaning the Intel part is more than seven times faster in this compute workload.

This result aligns with the broader specification gap. The Arc A770M's FP32 throughput of 16.79 TFLOPS dwarfs the R9 M380's 1.536 TFLOPS, an 11x difference. Its memory bandwidth of 512.0 GB/s versus 96.00 GB/s gives it a 5.3x advantage in data movement, which heavily influences OpenCL workloads that are often memory-bound.

The Arc A770M's average benchmark score of 18,383 places it just 0.1% above the AMD Radeon RX 460 and 1.2% above the NVIDIA GeForce RTX 3060 Mobile. This positions it as a mid-range mobile GPU in the current landscape. The R9 M380's average score of 15,521 puts it 0.2% below the NVIDIA GeForce GTX 1080 Ti, which is notable given the GTX 1080 Ti's historical status as a high-end desktop card. However, the R9 M380's performance is over a decade old in design, and its benchmark coverage is limited to just two tests (Geekbench Metal and Geekbench OpenCL).

In the only head-to-head result, the Arc A770M wins 1 out of 1 tests, with the R9 M380 taking zero wins. The magnitude of the OpenCL delta suggests that the Intel part is in a different performance class entirely for compute tasks. For gaming, the Arc A770M's modern feature set, including DirectX 12 Ultimate and ray tracing, gives it capabilities the R9 M380 simply cannot match. The R9 M380's DirectX 12 (12_0) support is functional but lacks the advanced features of 12_2, such as mesh shaders and variable rate shading.

The data indicates that the Intel Arc A770M is the superior GPU by every measurable metric in the database. The R9 M380 remains relevant only for legacy workloads or systems where its specific feature set is required.
