AMD Ryzen Z2 Extreme GPU vs Intel Arc A380E Comparison

Where Each One Wins

The recorded benchmark data for this comparison is notably lopsided. The AMD Ryzen Z2 Extreme GPU has a single recorded 3DMark Steel Nomad DX12 score of 516, while the Intel Arc A380E has no benchmark entries in the database at all. This means the comparative analysis must rely on the AMD part's nearest rival results and the architectural specifications of both products.

The AMD Ryzen Z2 Extreme GPU sits at the 1st percentile of all GPUs in the database. Its average benchmark score of 516 places it within a narrow band of older integrated and discrete parts. Against its nearest rivals, the AMD part trails the Intel HD Graphics P4000 by 3.4 percent (534 score) and the AMD Radeon HD 6870 by 3.7 percent (536 score). It beats the AMD Radeon HD 6750M by 6.6 percent (484 score) and trails the AMD Radeon HD 6770M by 9.3 percent (569 score). These deltas suggest the Ryzen Z2 Extreme GPU performs at a level comparable to early-2010s discrete graphics, which is a relevant data point for its intended console-class role.

The Intel Arc A380E, by contrast, has no recorded benchmark scores and no nearest rivals listed. Its percentile ranking of 50 indicates the database places it at the median of all GPUs, but without a measured score, every performance conclusion must be drawn from specifications alone. The A380E delivers 4.096 TFLOPS FP32 performance, a 2000 MHz base and boost clock, and 6 GB of GDDR6 memory on a 96-bit bus with 186.0 GB/s bandwidth. The Ryzen Z2 Extreme GPU delivers 5.530 TFLOPS FP32, a 2700 MHz boost clock, and 16 GB of LPDDR5X memory on a 128-bit bus with 128.0 GB/s bandwidth. On raw compute throughput, the AMD part holds a 35 percent advantage in FP32. On memory bandwidth, the Intel part holds a 45.3 percent advantage.

The use-case split becomes clear from these numbers. The AMD Ryzen Z2 Extreme GPU wins on peak shader throughput, pixel fill rate (129.6 GPixel/s versus 64.00 GPixel/s), texture fill rate (172.8 GTexel/s versus 128.0 GTexel/s), and memory capacity. The Intel Arc A380E wins on memory bandwidth, sustained clock stability (2000 MHz base equals boost), and display output flexibility with four DisplayPort 2.0 outputs versus a single USB Type-C output on the AMD part.

Architecture Differences

The two products come from different architectural generations and design philosophies. The AMD Ryzen Z2 Extreme GPU uses the Strix Point chip built on RDNA 3.5 architecture, fabricated on a 4 nm TSMC process. It integrates 34,000 million transistors on a 233 mm² die, yielding a transistor density of 145.9 million transistors per mm². The chip is classified as a console GPU, reflecting its design for embedded or handheld gaming systems rather than a standalone desktop card.

The Intel Arc A380E uses the DG2-128 chip built on Xe-HPG architecture, part of the Alchemist generation (Arc 3). It is fabricated on a 6 nm TSMC process with 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9 million transistors per mm². The A380E is marked as end-of-life, with its predecessor listed as Xe Graphics and successor as Battlemage.

The process node difference is significant. The 4 nm node allows 3.2 times the transistor density of the 6 nm node, which explains how the AMD chip packs nearly five times more transistors into a die that is only 48 percent larger by area. The AMD part uses 16 GB of LPDDR5X memory on a 128-bit bus, while the Intel part uses 6 GB of GDDR6 on a 96-bit bus. The memory types reflect different design targets: LPDDR5X is optimized for low-power integrated use, while GDDR6 is a dedicated discrete memory standard.

Both parts share identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have 1024 shading units and 64 texture mapping units. The AMD part has 48 raster operation units and 16 ray tracing cores, while the Intel part has 32 ROPs and 8 ray tracing cores. The AMD part's FP16 throughput is identical to its FP32 at 5.530 TFLOPS (1:1 ratio), while the Intel part's FP16 throughput is double its FP32 at 8.192 TFLOPS (2:1 ratio). This gives the Intel part a 48 percent advantage in FP16 compute, which can matter for workloads that use half-precision math.

The power envelopes diverge sharply. The AMD Ryzen Z2 Extreme GPU has a 28 W TDP with no power connectors, while the Intel Arc A380E has a 75 W TDP, no power connectors, and a suggested PSU of 250 W. The Intel part is a single-slot card measuring 254 mm in length, 127 mm in height, and 20 mm in width. The AMD part has no listed dimensions, reinforcing its role as an integrated or embedded component. The Intel part uses a PCIe 4.0 x8 bus interface, while the AMD part has no listed bus interface.

The Verdict

The data indicates that the AMD Ryzen Z2 Extreme GPU and the Intel Arc A380E serve different roles despite sharing some architectural similarities. The AMD part is designed for a low-power, integrated console context: 28 W TDP, 16 GB of LPDDR5X, a single USB Type-C display output, and no expansion slot. The Intel part is a discrete, single-slot card with 75 W TDP, four DisplayPort 2.0 outputs, and a 250 W suggested PSU.

On measured performance, the AMD Ryzen Z2 Extreme GPU scores 516 in 3DMark Steel Nomad DX12, which places it 3.4 percent behind the Intel HD Graphics P4000 and 3.7 percent behind the AMD Radeon HD 6870. It is 6.6 percent ahead of the AMD Radeon HD 6750M and 9.3 percent behind the AMD Radeon HD 6770M. These comparisons place the AMD part in a performance tier that is modest by modern standards, consistent with a 28 W integrated solution.

The Intel Arc A380E has no benchmark score in the database, making a direct measured comparison impossible. Its 50th percentile ranking versus the AMD part's 1st percentile ranking suggests the database views the Intel part as a mid-range performer, but this is a ranking without a supporting score. Specifications indicate the Intel part has superior memory bandwidth (186.0 GB/s versus 128.0 GB/s), higher base clock stability (2000 MHz flat versus 800 MHz base), and double the FP16 throughput (8.192 TFLOPS versus 5.530 TFLOPS). The AMD part counters with 35 percent higher FP32 throughput (5.530 TFLOPS versus 4.096 TFLOPS), double the pixel fill rate (129.6 GPixel/s versus 64.00 GPixel/s), 35 percent higher texture fill rate (172.8 GTexel/s versus 128.0 GTexel/s), and more than double the memory capacity (16 GB versus 6 GB).

For a use case requiring sustained FP32 compute, high fill rates, and large memory capacity in a low-power envelope, the AMD Ryzen Z2 Extreme GPU is the clear choice from the recorded data. For a use case requiring high memory bandwidth, half-precision compute, multiple display outputs, and a standard PCIe slot, the Intel Arc A380E aligns better with those needs. The absence of a benchmark score for the Intel part means its performance claims rest entirely on architectural specifications.
