AMD Ryzen Z2 Go GPU vs Intel Arc A380M Comparison

Head-to-Head Benchmarks

The recorded data for both the AMD Ryzen Z2 Go GPU and the Intel Arc A380M shows no head-to-head benchmark results in the database. Neither GPU has any individual benchmark scores listed, and their average benchmark scores are both recorded as zero. The wins counter for each side is also zero, meaning there are no direct performance comparisons available from our measurements.

What the database does provide is a percentile ranking for each product. Both the AMD Ryzen Z2 Go GPU and the Intel Arc A380M sit at the 50th percentile against all GPUs. This places both parts squarely in the middle of the overall performance distribution, though without concrete benchmark scores, the percentile alone cannot be used to separate them in raw compute tasks.

The closest thing to a performance comparison comes from the raw specifications that drive real-world results. The AMD Ryzen Z2 Go GPU delivers 4.147 TFLOPS of FP32 compute, while the Intel Arc A380M delivers 4.096 TFLOPS. The difference is 0.051 TFLOPS, which is a margin of roughly 1.2% in favor of the AMD part. In FP16, the AMD part reaches 8.294 TFLOPS (2:1), and the Intel part reaches 8.192 TFLOPS (2:1), again a narrow margin in AMD's favor.

Texture throughput is nearly identical. The AMD Ryzen Z2 Go GPU reaches 129.6 GTexel/s, and the Intel Arc A380M reaches 128.0 GTexel/s. Pixel throughput favors the AMD part more clearly: 86.40 GPixel/s versus 64.00 GPixel/s, a 35% advantage for the AMD GPU. This suggests the AMD part has a stronger fill-rate profile for rasterization work that depends on pixel output.

Memory bandwidth tells the opposite story. The Intel Arc A380M uses GDDR6 memory on a 96-bit bus and reaches 186.0 GB/s. The AMD Ryzen Z2 Go GPU uses LPDDR5 memory on a 128-bit bus and reaches 102.4 GB/s. Intel's part has 83.6 GB/s more bandwidth, which is an 82% advantage. This is the largest single gap between the two GPUs in any measured specification.

Clock behavior also differs. The Intel Arc A380M runs at a 1550 MHz base clock and a 2000 MHz boost clock. The AMD Ryzen Z2 Go GPU runs at an 800 MHz base clock and a 2700 MHz boost clock. The AMD part has a much higher boost ceiling, while the Intel part has nearly double the base clock. The AMD part compensates for its lower base clock with a 700 MHz higher boost clock.

The power envelope is not equal. The AMD Ryzen Z2 Go GPU has a 28 W TDP, while the Intel Arc A380M has a 35 W TDP. The database does not contain performance-per-watt benchmarks, but the raw numbers indicate the AMD part delivers comparable compute throughput while drawing less power on paper.

The Verdict

The data indicates that neither GPU has a recorded benchmark victory over the other. Both sit at the 50th percentile among all GPUs, and both have zero average benchmark scores. The choice between them depends entirely on which hardware priorities matter more.

The AMD Ryzen Z2 Go GPU is positioned for scenarios where pixel throughput and compute density matter. Its 86.40 GPixel/s pixel rate is 35% higher than the Intel part, and its FP32 output of 4.147 TFLOPS edges out the Intel part's 4.096 TFLOPS. It also packs 13,100 million transistors on a 208 mm² die, giving it a transistor density of 63.0M per mm². The 28 W TDP is lower than the Intel part's 35 W TDP, which matters for thermally constrained systems.

The Intel Arc A380M is positioned for scenarios where memory bandwidth is the limiting factor. Its 186.0 GB/s bandwidth is 82% higher than the AMD part's 102.4 GB/s. It also has more shading units (1024 versus 768) and more texture mapping units (64 versus 48), which can help in workloads that scale with shader count. The 2000 MHz boost clock is lower than the AMD part's 2700 MHz, but the 1550 MHz base clock is nearly double the AMD part's 800 MHz base.

The AMD part uses the RDNA 2.0 architecture, while the Intel part uses Xe-HPG. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have ray tracing cores, with the AMD part carrying 12 and the Intel part carrying 8.

Clock behavior is also distinct. The AMD part has an 800 MHz base clock and a 2700 MHz boost clock. The Intel part has a 1550 MHz base clock and a 2000 MHz boost clock. Memory clocks differ too: the AMD part runs at 800 MHz with 6.4 Gbps effective transfer, while the Intel part runs at 1937 MHz with 15.5 Gbps effective transfer.

The power delivery and form factor differ as well. The AMD Ryzen Z2 Go GPU has a 28 W TDP, no power connectors, and a single USB Type-C display output. The Intel Arc A380M has a 35 W TDP, uses an MXM Module slot width, an MXM-A (3.1) bus interface, and its display outputs are described as portable device dependent.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins on pixel throughput. Its 86.40 GPixel/s rate is 35% higher than the Intel Arc A380M's 64.00 GPixel/s. This matters for workloads that are heavy on fill rate, such as high-resolution rasterization with depth and stencil operations.

The AMD part also wins on compute density. Its FP32 output of 4.147 TFLOPS is slightly above the Intel part's 4.096 TFLOPS, and its FP16 output of 8.294 TFLOPS is slightly above the Intel part's 8.192 TFLOPS. The margins are small, but they are consistent across both precision formats.

The AMD part wins on memory capacity. Its 16 GB of LPDDR5 is more than double the Intel part's 6 GB of GDDR6. For workloads that need large working sets, such as high-resolution texture data or machine learning inference with larger models, the extra capacity is a clear advantage.

The AMD part wins on power efficiency on paper. Its 28 W TDP is 7 W lower than the Intel part's 35 W TDP while delivering slightly higher compute throughput. The AMD part also uses no power connectors, which simplifies integration.

The Intel Arc A380M wins on memory bandwidth. Its 186.0 GB/s is 82% higher than the AMD part's 102.4 GB/s. This matters for memory-bound workloads where data movement, not compute, is the bottleneck. The GDDR6 memory also runs at a much higher effective transfer rate of 15.5 Gbps versus 6.4 Gbps.

The Intel part wins on shader count. Its 1024 shading units are 33% more than the AMD part's 768 shading units. It also has 64 texture mapping units versus 48, a 33% advantage. Workloads that scale with parallel shader execution may favor the Intel part despite its slightly lower FP32 ceiling.

The Intel part wins on base clock stability. Its 1550 MHz base clock is nearly double the AMD part's 800 MHz base clock, which means it sustains a higher minimum performance floor under sustained loads.

The AMD part wins on transistor density. Its 63.0M transistors per mm² is higher than the Intel part's 45.9M per mm², and the AMD die is larger at 208 mm² versus 157 mm². The AMD part also has more ray tracing cores, 12 versus 8.

Neither GPU has a recorded benchmark score or a head-to-head win in the database, so these conclusions are drawn strictly from the specification data. The AMD Ryzen Z2 Go GPU suits systems where pixel throughput, memory capacity, and low power draw are the priorities. The Intel Arc A380M suits systems where memory bandwidth and shader count are the priorities.
