AMD Radeon 8065S vs Intel Arc A380M Comparison

The Verdict

The recorded data positions the AMD Radeon 8065S and Intel Arc A380M as two distinctly different mobile graphics solutions, each suited to different system designs and workload priorities. The AMD Radeon 8065S, built on the Gorgon Halo chip with RDNA 3.5 architecture, delivers substantially higher raw compute throughput, memory bandwidth, and pixel/texture processing capabilities. The Intel Arc A380M, based on the DG2-128 chip with Xe-HPG architecture, offers a lower thermal envelope and a smaller die, making it a fit for compact or power-constrained portable devices.

The benchmark results indicate that the AMD Radeon 8065S is the stronger performer across every measured throughput metric. It provides 15.36 TFLOPS of FP32 compute, which is 3.75 times the 4.096 TFLOPS of the Intel part. Pixel fill rate on the AMD reaches 192.0 GPixel/s versus 64.00 GPixel/s on Intel, a 3x advantage. Texture fill rate likewise favors AMD at 480.0 GTexel/s against 128.0 GTexel/s, a 3.75x margin. These deltas are substantial and consistent across the board.

However, the Intel Arc A380M is not without its own merits. Its 35 W TDP is lower than the 55 W TDP of the AMD Radeon 8065S, meaning it draws less power and generates less heat. The Intel GPU also has a smaller die size at 157 mm² compared to 308 mm² for AMD, which could translate to lower manufacturing costs per wafer, though pricing data is not available in the database. The Intel part also uses a dedicated 6 GB GDDR6 memory pool with a 96-bit bus and 186.0 GB/s bandwidth, whereas the AMD Radeon 8065S relies on system shared memory, making its bandwidth dependent on the host platform.

For users who prioritize maximum frame rates and compute throughput in a portable device, the AMD Radeon 8065S is the clear choice based on the numbers. For users who need a lower-power discrete GPU with dedicated video memory and a smaller physical footprint, the Intel Arc A380M provides a more efficient option. The data does not include actual game benchmark scores, so the verdict rests entirely on the specification-derived throughput metrics, but those metrics uniformly favor AMD.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part interfaces with the host via PCIe 5.0 x16, while the Intel part uses an MXM-A (3.1) bus interface. The AMD Radeon 8065S is designed as an integrated graphics processor (IGP) with no power connectors, whereas the Intel Arc A380M is a discrete MXM module. Both have display outputs that are portable device dependent, meaning the actual ports vary by laptop design.

Specification Differences

The AMD Radeon 8065S and Intel Arc A380M differ across nearly every specification field in the database. The process node is 4 nm for AMD versus 6 nm for Intel. The die size is 308 mm² for AMD versus 157 mm² for Intel. The transistor count is unknown for AMD, while Intel lists 7,200 million transistors and a density of 45.9 million per mm².

Clock speeds differ significantly. The AMD Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The Intel Arc A380M has a base clock of 1550 MHz and a boost clock of 2000 MHz. Memory clocks are listed as system shared for AMD, while Intel has a memory clock of 1937 MHz with 15.5 Gbps effective data rate.

Memory configuration is a major differentiator. AMD uses system shared memory with system dependent bandwidth, while Intel uses 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth. The shading units count is 2560 for AMD versus 1024 for Intel. TMUs are 160 versus 64, and ROPs are 64 versus 32. Ray tracing cores are 40 versus 8.

Pixel rate is 192.0 GPixel/s for AMD and 64.00 GPixel/s for Intel. Texture rate is 480.0 GTexel/s for AMD and 128.0 GTexel/s for Intel. FP32 performance is 15.36 TFLOPS for AMD and 4.096 TFLOPS for Intel. FP16 performance is 15.36 TFLOPS with a 1:1 ratio for AMD, and 8.192 TFLOPS with a 2:1 ratio for Intel.

AMD has no power connectors, while Intel does not list power connector information. The bus interface is PCIe 5.0 x16 for AMD and MXM-A (3.1) for Intel. The release dates also differ, with AMD released on 2025-12-31 and Intel released on 2023-01-23. The AMD part lists Polaris Mobile as its predecessor, while Intel has no predecessor listed.

Head-to-Head Benchmarks

The database contains no actual benchmark scores for either GPU, and the head-to-head benchmark array is empty. However, the specification-derived throughput metrics provide a clear quantitative comparison across all compute and rasterization categories.

In FP32 compute, the AMD Radeon 8065S delivers 15.36 TFLOPS, which is 11.264 TFLOPS higher than the Intel Arc A380M's 4.096 TFLOPS. This represents a 275% advantage for AMD. The FP16 comparison shows AMD at 15.36 TFLOPS (1:1 ratio) versus Intel at 8.192 TFLOPS (2:1 ratio). The AMD part still leads by 7.168 TFLOPS, though the margin narrows to 87.5% because Intel's FP16 path runs at double rate.

Pixel fill rate favors AMD at 192.0 GPixel/s versus 64.00 GPixel/s for Intel. This is a 128.0 GPixel/s difference, or exactly 3 times higher on AMD. Texture fill rate shows AMD at 480.0 GTexel/s versus 128.0 GTexel/s for Intel, a 352.0 GTexel/s gap that again works out to a 3.75x advantage for AMD. These ratios directly mirror the shading unit and TMU counts, which are 2.5x and 2.5x higher on AMD respectively, combined with the higher boost clock of 3000 MHz versus 2000 MHz.

Memory bandwidth is where the comparison flips. The Intel Arc A380M has a fixed 186.0 GB/s from its 6 GB GDDR6 pool on a 96-bit bus. The AMD Radeon 8065S uses system shared memory, and its bandwidth is listed as system dependent. This means the effective bandwidth of the AMD part cannot be stated from the database alone; it depends entirely on the host system's memory configuration. In a laptop with high-speed system memory, the AMD part could potentially exceed 186.0 GB/s, but the database does not provide a confirmatory figure.

Ray tracing resources also differ sharply. The AMD Radeon 8065S has 40 RT cores, while the Intel Arc A380M has 8 RT cores. This 5x difference in RT core count suggests a significant advantage for AMD in ray-traced workloads, though no benchmark scores are available to quantify actual frame rate impacts.

The TDP difference of 20 W (55 W versus 35 W) means the AMD part draws 57% more power than the Intel part. This power gap is smaller than the compute gap, indicating that AMD achieves higher throughput per watt in raw FP32, but the Intel part may have an efficiency advantage in certain memory-bound or lightly threaded workloads given its lower power draw and dedicated memory.

Both GPUs share the same API support, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The release timing differs by nearly three years, with Intel launching on 2023-01-23 and AMD on 2025-12-31. The production status for both is listed as active, meaning both are currently available in the market.

The percentile versus all GPUs is listed as 50 for both parts, which is the median percentile. The average benchmark score is zero for both, reflecting the absence of benchmark data in the database rather than actual performance measurements. The nearest rivals arrays are empty for both GPUs, so no direct competitor comparisons from the database can be cited. All conclusions in this analysis derive from the specification data, which consistently shows the AMD Radeon 8065S with a substantial throughput advantage across compute, pixel, and texture rates, while the Intel Arc A380M offers a lower power envelope and a fixed dedicated memory pool.
