AMD Ryzen AI Z2 Extreme GPU vs Intel Arc A380E Comparison

The Verdict

The AMD Ryzen AI Z2 Extreme GPU and Intel Arc A380E occupy similar performance percentiles, both sitting at the 50th percentile versus all GPUs in the database. However, the data shows two fundamentally different design philosophies. The AMD part is a low-power, integrated-style solution with a 28 W TDP, 16 GB of LPDDR5X memory, and a 256-bit bus, while the Intel part is a discrete, single-slot card with a 75 W TDP, 6 GB of GDDR6 memory, and a 96-bit bus. The AMD GPU delivers higher raw throughput in pixel and texture rates, while the Intel GPU offers a higher base clock and a different memory configuration. For users prioritizing sustained compute in a constrained power envelope, the AMD Ryzen AI Z2 Extreme GPU is the clear choice based on its higher FP32 throughput and memory bandwidth. For users needing multiple display outputs and a standard PCIe form factor, the Intel Arc A380E provides a more conventional discrete GPU layout, though with lower overall throughput metrics.

Architecture Differences

The AMD Ryzen AI Z2 Extreme GPU uses the RDNA 3.5 architecture on a 4 nm process node from TSMC, built on the Strix Point chip. This is a console-grade GPU generation from AMD, integrating 34,000 million transistors on a 233 mm² die, yielding a transistor density of 145.9M per mm². The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its memory subsystem uses LPDDR5X running at 1000 MHz with 8 Gbps effective speed, across a 256-bit bus, producing 256.0 GB/s of bandwidth. The GPU has 1024 shading units, 64 texture mapping units, 48 raster output units, and 16 ray tracing cores. Its FP32 performance is 5.530 TFLOPS, while FP16 performance is also 5.530 TFLOPS at a 1:1 ratio, indicating no dedicated half-rate path for FP16.

The Intel Arc A380E uses the Xe-HPG architecture on a 6 nm process node from TSMC, based on the DG2-128 chip, part of the Alchemist generation under Arc 3. It packs 7,200 million transistors on a 157 mm² die, with a transistor density of 45.9M per mm². This is a notably lower density, reflecting the larger process node. The architecture also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Memory is GDDR6 at 1937 MHz with 15.5 Gbps effective speed, across a 96-bit bus, delivering 186.0 GB/s of bandwidth. It shares the same 1024 shading units and 64 TMUs but has only 32 ROPs and 8 ray tracing cores. FP32 performance is 4.096 TFLOPS, while FP16 performance is 8.192 TFLOPS at a 2:1 ratio, meaning FP16 throughput is exactly double the FP32 rate.

The process node difference is significant: 4 nm versus 6 nm. The AMD part achieves over three times the transistor density (145.9M versus 45.9M per mm²) despite having a larger die. The AMD GPU also has double the ROPs (48 versus 32) and double the ray tracing cores (16 versus 8). The Intel part has a much higher boost clock (2000 MHz versus 2700 MHz for AMD), but this does not compensate for the lower architectural throughput in FP32.

Where Each One Wins

The AMD Ryzen AI Z2 Extreme GPU wins on every throughput metric recorded in the database. Its FP32 compute is 5.530 TFLOPS versus 4.096 TFLOPS for Intel, a 35% advantage. Pixel rate is 129.6 GPixel/s versus 64.00 GPixel/s, more than double. Texture rate is 172.8 GTexel/s versus 128.0 GTexel/s, a 35% lead. Memory bandwidth is 256.0 GB/s versus 186.0 GB/s, a 37.6% advantage. The AMD GPU also has a larger memory capacity (16 GB versus 6 GB), a wider bus (256-bit versus 96-bit), and a much lower TDP (28 W versus 75 W). The AMD part supports a 1:1 FP16 ratio, which means FP16 workloads run at the same rate as FP32, while the Intel part has a 2:1 ratio, meaning FP16 runs at double the FP32 rate. This gives Intel an FP16 throughput advantage: 8.192 TFLOPS versus 5.530 TFLOPS.

The Intel Arc A380E wins on clock speed, with a base and boost clock of 2000 MHz, while the AMD GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. Intel also offers four DisplayPort 2.0 outputs versus a single USB Type-C on the AMD part. The Intel GPU is a single-slot card with PCIe 4.0 x8 interface, while the AMD GPU has no slot width or bus interface recorded. The Intel part has a suggested PSU of 250 W, while the AMD has no such requirement. The Intel GPU is end-of-life, while the AMD GPU is active production. The Intel part has a predecessor (Xe Graphics) and a successor (Battlemage), while the AMD part has neither recorded.
