AMD Ryzen Z2 A GPU vs Intel Arc A380M Comparison

Head-to-Head Benchmarks

The recorded data does not contain any direct head-to-head benchmark results between the AMD Ryzen Z2 A GPU and the Intel Arc A380M. The database lists no win counts for either part, and there are no average benchmark scores or percentile rankings that differentiate them. Both GPUs sit at the 50th percentile against all GPUs in the database, which places them in the same broad performance tier based on the available metrics.

Without direct comparison scores, the analysis relies on the architectural and specification data recorded for each product. The Intel Arc A380M carries a significantly higher FP32 compute figure of 4.096 TFLOPS compared to the AMD Ryzen Z2 A GPU's 1.638 TFLOPS, a difference of roughly 2.5 times in raw shader throughput. The Intel part also reports a texture rate of 128.0 GTexel/s and a pixel rate of 64.00 GPixel/s, while the AMD part reports 51.20 GTexel/s and 25.60 GPixel/s respectively. These figures indicate that the Intel Arc A380M delivers more than double the fill rate in both texture and pixel processing.

Memory bandwidth also favors the Intel part, with 186.0 GB/s against the AMD part's 102.4 GB/s. The Intel GPU uses 6 GB of GDDR6 memory on a 96-bit bus, while the AMD GPU uses 16 GB of LPDDR5 memory on a 128-bit bus. The AMD part compensates with a larger memory pool, but the bandwidth gap is substantial: the Intel part offers roughly 82% more bandwidth per second.

Clock speeds favor the Intel part as well. The Arc A380M runs at a 1550 MHz base clock and 2000 MHz boost clock, whereas the Ryzen Z2 A GPU runs at 1000 MHz base and 1600 MHz boost. The Intel GPU's higher clocks contribute directly to its higher throughput and fill rates. The AMD part's advantage lies in its memory capacity and lower power envelope.

Where Each One Wins

The AMD Ryzen Z2 A GPU wins on memory capacity, offering 16 GB of LPDDR5 memory compared to the Intel Arc A380M's 6 GB of GDDR6. This larger pool is relevant for workloads or settings that exceed 6 GB of frame buffer usage, such as high-resolution textures or certain compute tasks that require substantial resident data. The AMD part also operates at a 15 W TDP, less than half of the Intel part's 35 W TDP, which points to a more power-efficient design for thermally constrained systems.

The Intel Arc A380M wins on raw compute metrics across every throughput category in the recorded data. Its FP32 performance of 4.096 TFLOPS more than doubles the AMD part's 1.638 TFLOPS. FP16 performance follows the same pattern: 8.192 TFLOPS versus 3.277 TFLOPS, both at a 2:1 ratio. The Intel part also doubles the texture unit count (64 TMUs versus 32) and the render output unit count (32 ROPs versus 16), which directly explains its higher texture and pixel rates. Shader unit count is 1024 versus 512, again a 2:1 advantage.

Memory bandwidth is another clear win for the Intel part. The 186.0 GB/s bandwidth exceeds the AMD part's 102.4 GB/s by a wide margin, even though the AMD part uses a wider 128-bit bus. The GDDR6 memory type on the Intel part runs at 15.5 Gbps effective, while the AMD part's LPDDR5 runs at 6.4 Gbps effective. The higher per-pin data rate on the Intel part overcomes its narrower bus.

The Intel part also holds a node advantage, using a 6 nm process from TSMC versus the AMD part's 7 nm process from the same foundry. Transistor density reflects this: 45.9M transistors per square millimeter on the Intel part versus 14.7M on the AMD part. The Intel chip packs 7,200 million transistors into a 157 mm² die, while the AMD chip uses 2,400 million transistors across 163 mm².

Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, classified under Console GPU (AMD). The Intel Arc A380M uses the DG2-128 chip with Xe-HPG architecture, classified under Alchemist (Arc 3 Mobile). Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical in the recorded data.

The Intel part integrates 8 ray tracing cores, and the AMD part also lists 8 RT cores. Both parts therefore present the same ray tracing core count, though the architectures implement ray tracing differently. Neither part lists tensor cores in the database.

Process technology differs by one node generation. The Intel part is built on TSMC's 6 nm process, while the AMD part uses TSMC's 7 nm process. The Intel die measures 157 mm² with 7,200 million transistors, yielding a density of 45.9M transistors per square millimeter. The AMD die measures 163 mm² with 2,400 million transistors, yielding 14.7M per square millimeter. The Intel part achieves roughly three times the transistor density despite a slightly smaller die.

Memory architecture differs fundamentally. The AMD part uses 16 GB of LPDDR5 on a 128-bit bus at 800 MHz, 6.4 Gbps effective, producing 102.4 GB/s. The Intel part uses 6 GB of GDDR6 on a 96-bit bus at 1937 MHz, 15.5 Gbps effective, producing 186.0 GB/s. The AMD part trades bandwidth for capacity, while the Intel part does the reverse. Both memory types are soldered or module-based rather than user-upgradeable, but the Intel part's MXM Module form factor suggests a replaceable module design.

The Intel part's display output is listed as "Portable Device Dependent," and it uses an MXM-A (3.1) bus interface with a slot width of one MXM Module. The AMD part lists a single USB Type-C display output with no bus interface or slot width recorded. The AMD part's TDP is 15 W, the Intel part's is 35 W. No power connectors or suggested PSU ratings are recorded for either part. No dimensions are recorded for either part.

Release dates differ by just under a year. The Intel Arc A380M was released on January 23, 2023, while the AMD Ryzen Z2 A GPU was released on December 31, 2024. Both parts are marked as Active in production status. Neither part has a predecessor or successor listed, and neither has a launch MSRP recorded.

The Verdict

The recorded data shows two parts aimed at different trade-offs. The Intel Arc A380M delivers substantially higher compute throughput, fill rates, and memory bandwidth, all at a 35 W TDP. Its FP32 figure of 4.096 TFLOPS is 2.5 times the AMD part's 1.638 TFLOPS, and its pixel rate of 64.00 GPixel/s is 2.5 times the AMD part's 25.60 GPixel/s. For workloads that rely on raw shader throughput or texture and pixel fill, the Intel part is clearly stronger on paper.

The AMD Ryzen Z2 A GPU offers 16 GB of memory, which is more than double the Intel part's 6 GB. It also operates at 15 W, a 20 W lower power envelope than the Intel part. These two factors point to a design optimized for power-constrained or memory-hungry scenarios, not for peak throughput. The AMD part's 102.4 GB/s bandwidth is a limiting factor, but its larger frame buffer may allow it to run workloads that would exceed the Intel part's memory capacity.

The 50th percentile ranking for both parts against all GPUs in the database suggests they occupy a similar overall tier, but the internal metrics diverge sharply. The Intel part wins every throughput and bandwidth comparison in the database. The AMD part wins on memory capacity and power efficiency. A system designer choosing between the two would weigh the Intel part's 2.5x FP32 advantage against the AMD part's 10 GB additional memory and 20 W lower TDP. The data does not record any benchmark results that would further contextualize these trade-offs.
