AMD Ryzen Z1 Extreme GPU vs Intel Arc A380E Comparison

The Verdict

The recorded data positions the AMD Ryzen Z1 Extreme GPU and Intel Arc A380E as two fundamentally different solutions that happen to share a performance percentile. Both sit at the 50th percentile against all GPUs in the database, with no benchmark scores available for either part, so the comparison rests on architectural specifications, memory subsystems, and feature sets rather than measured frame rates.

The AMD Ryzen Z1 Extreme GPU is a console-class processor with integrated graphics, built on the Phoenix chip with RDNA 3.0 architecture. It offers 16 GB of LPDDR5 memory, 768 shading units, 12 ray tracing cores, and a 30 W TDP. This part is designed for compact, power-constrained devices where unified memory and low power draw matter more than raw bandwidth. The data shows it carries a launch MSRP of 699 USD.

The Intel Arc A380E is a discrete, single-slot graphics card from the Alchemist generation, using the DG2-128 chip on Xe-HPG architecture. It provides 6 GB of GDDR6 memory on a 96-bit bus, 1024 shading units, 8 ray tracing cores, and a 75 W TDP. It requires a 250 W suggested power supply and connects via PCIe 4.0 x8. The Intel part is end-of-life, while the AMD part remains active in production.

For users prioritizing memory capacity and ray tracing throughput per watt, the AMD Ryzen Z1 Extreme GPU is the data-supported choice. For users needing a standalone card with higher memory bandwidth, more shading units, and four DisplayPort outputs, the Intel Arc A380E is the better fit. Neither part has benchmark scores in the database, so the verdict relies on specification-level advantages.

Architecture Differences

The two GPUs come from different architectural families. The AMD Ryzen Z1 Extreme GPU uses RDNA 3.0 on the Phoenix chip, fabricated on a 4 nm process at TSMC. The Intel Arc A380E uses Xe-HPG on the DG2-128 chip, fabricated on a 6 nm process at TSMC. The process node difference gives AMD a density advantage: the Phoenix chip packs 25,390 million transistors into a 178 mm² die, yielding a transistor density of 142.6M per mm². The DG2-128 chip contains 7,200 million transistors on a 157 mm² die, for a density of 45.9M per mm².

The AMD chip integrates 768 shading units, 48 texture mapping units, and 32 raster operation pipelines. It also includes 12 ray tracing cores. The Intel chip offers more shading units at 1024, more TMUs at 64, and the same 32 ROPs, but fewer ray tracing cores at 8. In raw shading capacity, the Intel part has 33% more shading units than the AMD part. In ray tracing hardware, the AMD part has 50% more RT cores than the Intel part.

Clock behavior differs substantially. The AMD Ryzen Z1 Extreme GPU runs at a base clock of 800 MHz and boosts to 2700 MHz, a 3.375x multiplier from base to boost. The Intel Arc A380E runs at a fixed 2000 MHz for both base and boost, meaning no dynamic clock range. The AMD part's boost clock is 35% higher than the Intel part's fixed clock, which helps close the shading unit gap.

Memory architecture is where the two diverge most clearly. The AMD part uses 16 GB of LPDDR5 on a 64-bit bus, with memory clocked at 800 MHz and 6.4 Gbps effective, producing 51.20 GB/s of bandwidth. The Intel part uses 6 GB of GDDR6 on a 96-bit bus, with memory at 1937 MHz and 15.5 Gbps effective, producing 186.0 GB/s of bandwidth. The Intel card has 3.63x the memory bandwidth of the AMD part, despite having 10 GB less capacity. The AMD part has 2.67x the memory capacity of the Intel part.

Compute throughput also favors different workloads. The AMD part delivers 8.294 TFLOPS of FP32 performance and 16.59 TFLOPS of FP16 performance (at 2:1 ratio). The Intel part delivers 4.096 TFLOPS of FP32 and 8.192 TFLOPS of FP16 (also at 2:1). The AMD part has 2.02x the FP32 throughput and 2.02x the FP16 throughput of the Intel part. Pixel and texture rates tell a mixed story: the AMD part achieves 86.40 GPixel/s against the Intel's 64.00 GPixel/s, a 35% advantage, while texture rates are nearly identical at 129.6 GTexel/s versus 128.0 GTexel/s.

Power envelopes differ by 2.5x. The AMD Ryzen Z1 Extreme GPU is rated at 30 W TDP, while the Intel Arc A380E is rated at 75 W TDP. The AMD part requires no power connectors and has no suggested PSU rating. The Intel part also uses no power connectors but lists a 250 W suggested PSU. The Intel card is single-slot; the AMD part is an integrated GPU with no slot width specified. Physical dimensions also differ: the AMD part measures 280 mm by 111 mm by 21 mm, while the Intel card measures 254 mm by 127 mm by 20 mm. The AMD part is longer, the Intel card is taller.

Display outputs differ significantly. The AMD part offers a single USB Type-C output. The Intel card provides four DisplayPort 2.0 outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part released on 2023-06-12 and remains active; the Intel part released on 2024-03-31 and is end-of-life, with predecessor Xe Graphics and successor Battlemage listed.

Where Each One Wins

The AMD Ryzen Z1 Extreme GPU wins in compute-heavy workloads that rely on FP32 and FP16 throughput. Its 8.294 TFLOPS FP32 and 16.59 TFLOPS FP16 figures are double the Intel part's corresponding numbers. For general-purpose GPU compute, physics simulations, or any workload that scales with raw floating-point operations, the AMD part holds a clear specification advantage.

The AMD part also wins on memory capacity. With 16 GB of LPDDR5, it holds 2.67x the memory of the Intel card's 6 GB. This matters for large datasets, high-resolution texture sets, or workloads that exceed 6 GB of working set. The unified memory architecture typical of the Phoenix chip also suggests system-level integration, though the database does not detail that aspect.

The AMD part wins on ray tracing core count. With 12 RT cores versus 8 on the Intel part, the AMD GPU has 50% more ray tracing hardware. For ray-traced effects, the AMD part's hardware advantage is directly supported by the data.

The AMD part wins on power efficiency. At 30 W TDP versus 75 W TDP, the AMD GPU delivers its higher compute throughput at 40% of the Intel part's power budget. The AMD part also has a higher boost clock (2700 MHz versus 2000 MHz) and a higher pixel rate (86.40 GPixel/s versus 64.00 GPixel/s).

The Intel Arc A380E wins on memory bandwidth. At 186.0 GB/s, it provides 3.63x the bandwidth of the AMD part's 51.20 GB/s. For workloads that are bandwidth-bound, such as high-resolution texture streaming, post-processing filters, or certain compression algorithms, the Intel card has a substantial edge.

The Intel part wins on shading unit count and texture mapping units. With 1024 shading units versus 768, and 64 TMUs versus 48, the Intel card has more parallel execution resources for shader-bound workloads. Its fixed 2000 MHz clock means consistent performance without boost variability.

The Intel part wins on display connectivity. Four DisplayPort 2.0 outputs versus a single USB Type-C output means the Intel card supports multi-monitor setups directly. The Intel part also has a higher base clock (2000 MHz versus 800 MHz), though the AMD part's boost clock exceeds it.

The Intel part wins on physical integration as a discrete card. It is single-slot, shorter in length (254 mm versus 280 mm), and has a wider bus interface (PCIe 4.0 x8, while the AMD part lists no bus interface). The Intel card also has a lower transistor count (7,200 million versus 25,390 million), which may simplify certain production aspects, though the AMD part's higher density suggests more efficient use of silicon area.
