AMD Ryzen Z2 A GPU vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the AMD Ryzen Z2 A GPU and the Intel Arc A380E. Both entries show an average benchmark score of zero, and the head-to-head benchmark array is empty. The recorded data therefore provides no measured frame rates, no synthetic scores, and no comparative performance percentages between these two parts. What the database does provide is a full architectural and specification breakdown, which allows a positional analysis based on hardware capabilities rather than tested outcomes.

The absence of benchmark data is itself informative. Neither GPU has a recorded wins tally, and both sit at the 50th percentile among all GPUs in the database, which places them at the median of the recorded field. Without measured scores, the comparison must rely on the raw compute, memory, and feature specifications that are present in the database. The AMD part delivers 1.638 TFLOPS of FP32 throughput, while the Intel part delivers 4.096 TFLOPS, a 2.5x difference in raw shader output. In FP16, the gap widens further: 3.277 TFLOPS for AMD versus 8.192 TFLOPS for Intel, again a 2.5x margin. The Intel Arc A380E also leads in pixel rate, at 64.00 GPixel/s versus 25.60 GPixel/s, and in texture rate, at 128.0 GTexel/s versus 51.20 GTexel/s. These are exact numbers from the database, and they indicate a consistent and substantial compute advantage for the Intel part across every throughput metric.

The AMD Ryzen Z2 A GPU, however, leads in memory capacity and power efficiency. The AMD part has 16 GB of LPDDR5 memory on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The Intel part has 6 GB of GDDR6 memory on a 96-bit bus, delivering 186.0 GB/s. Intel wins bandwidth by a factor of 1.8, but AMD wins capacity by a factor of 2.67. The thermal design power tells the rest of the story: the AMD part is rated at 15 W, while the Intel part is rated at 75 W, a 5x difference in power draw. The Intel part also lists a suggested PSU of 250 W, while the AMD part lists no power supply requirement at all.

The Verdict

From the recorded data, the Intel Arc A380E is the clear compute leader. It delivers 4.096 TFLOPS of FP32 performance, which is 2.5 times the AMD Ryzen Z2 A GPU's 1.638 TFLOPS. The Intel part also has twice the shading units (1024 versus 512), twice the texture mapping units (64 versus 32), and twice the render output units (32 versus 16). Both parts have 8 ray tracing cores, so that feature is a tie. The Intel part has a higher boost clock (2000 MHz versus 1600 MHz), a higher base clock (2000 MHz versus 1000 MHz), and a higher memory clock (1937 MHz versus 800 MHz). The Intel part is built on a smaller 6 nm process node from TSMC, versus the AMD part's 7 nm node, also from TSMC. The Intel chip packs 7,200 million transistors onto a 157 mm² die, while the AMD chip has 2,400 million transistors on a 163 mm² die. The transistor density difference is stark: 45.9M per mm² for Intel versus 14.7M per mm² for AMD.

The AMD Ryzen Z2 A GPU, however, is the efficiency and capacity leader. Its 15 W TDP is one-fifth of the Intel part's 75 W TDP. Its 16 GB of memory is more than double the Intel part's 6 GB. The AMD part is also the only one of the two with an active production status, while the Intel part is marked as end-of-life, with a listed predecessor (Xe Graphics) and successor (Battlemage). The AMD part has a later release date in the database (2024-12-31 versus 2024-03-31). These factors point to the AMD part being a current, low-power embedded or mobile solution, while the Intel part is a higher-performance, already-superseded discrete card.

Where Each One Wins

The Intel Arc A380E wins in raw compute, memory bandwidth, and display connectivity. Its 4.096 TFLOPS of FP32 and 8.192 TFLOPS of FP16 make it the stronger choice for any workload that leans on shader throughput, such as rendering, compute tasks, or higher-resolution gaming. Its 186.0 GB/s of memory bandwidth, delivered via GDDR6 on a 96-bit bus, gives it a 1.8x bandwidth advantage over the AMD part's 102.4 GB/s. The Intel part also offers four DisplayPort 2.0 outputs, while the AMD part offers a single USB Type-C output. The Intel part is a single-slot card with a 254 mm length, 127 mm height, and 20 mm width, and it requires no external power connectors, drawing solely from its 75 W TDP with a 250 W suggested PSU.

The AMD Ryzen Z2 A GPU wins in power efficiency, memory capacity, and production status. Its 15 W TDP is five times lower than the Intel part's 75 W, making it suitable for environments where heat and power are constrained. Its 16 GB of LPDDR5 memory provides 2.67 times the capacity of the Intel part's 6 GB, which matters for workloads that need to hold large datasets or multiple assets in memory simultaneously. The AMD part is also actively in production, whereas the Intel part is end-of-life, which means the AMD part remains a current option for new designs. The AMD part's single USB Type-C output suggests a compact, integrated form factor, likely for handheld or embedded systems, while the Intel part's four DisplayPort 2.0 outputs indicate a traditional multi-monitor desktop card.
