AMD Ryzen Z2 A GPU vs Intel Arc B580 Comparison

The Verdict

The recorded data separates these two GPUs into entirely different performance classes. The Intel Arc B580 holds a 68th percentile position among all GPUs in the database, while the AMD Ryzen Z2 A GPU sits at the 50th percentile. The Arc B580 carries an average benchmark score of 23021 across its recorded tests, whereas the Ryzen Z2 A GPU has no recorded benchmark scores, giving it an average of zero. The data indicates the Arc B580 is the only one of the two with measurable performance data, and it competes closely with established desktop graphics cards. The Arc B580 sits within 1% of several known rivals: it trails the AMD Radeon RX 580 2048SP by 0.2%, leads the NVIDIA GeForce RTX 2080 by 0.6%, trails the NVIDIA GeForce RTX 3080 by 0.7%, and trails the NVIDIA P106-100 by 1%. The Ryzen Z2 A GPU, by contrast, appears in the database with no benchmark entries, no rivals, and no average score, marking it as a part with incomplete or unrecorded performance data. The Arc B580 has a launch MSRP of 249 USD.

The verdict from the data is straightforward. The Intel Arc B580 is the choice for anyone seeking verifiable graphics performance, as it delivers 13.67 TFLOPS of FP32 compute, 456.0 GB/s of memory bandwidth, and a full suite of recorded benchmark results. The AMD Ryzen Z2 A GPU provides only 1.638 TFLOPS of FP32 compute and 102.4 GB/s of bandwidth, with no recorded results to validate its real-world behavior. The Ryzen Z2 A GPU also carries a 15 W TDP, which suggests it belongs to a low-power embedded or handheld segment, while the Arc B580 demands a 190 W TDP and a 450 W suggested PSU. For a desktop graphics workload, the Arc B580 is the only part with data supporting its capability. The Ryzen Z2 A GPU appears designed for scenarios where power consumption is the primary constraint, but no benchmark data exists to quantify its performance in that role.

Architecture Differences

The two GPUs share no architectural lineage. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. The Intel Arc B580 uses the BMG-G21 chip built on Xe2-HPG architecture, part of the Battlemage generation (Arc 5), manufactured on a 5 nm process, also at TSMC. The process node difference is meaningful: the Arc B580 packs 19,600 million transistors onto a 272 mm² die, achieving a transistor density of 72.1M per mm². The Ryzen Z2 A GPU contains only 2,400 million transistors on a 163 mm² die, with a density of 14.7M per mm². That represents a 17,200 million transistor gap between the two parts.

The compute resources amplify the architectural divide. The Arc B580 features 2,560 shading units, 160 texture mapping units, 80 render output units, and 20 ray tracing cores. The Ryzen Z2 A GPU offers 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The Arc B580 has five times the shading units, five times the TMUs, five times the ROPs, and 2.5 times the ray tracing cores. Pixel throughput reflects this: the Arc B580 reaches 213.6 GPixel/s versus 25.60 GPixel/s for the Ryzen Z2 A GPU. Texture throughput follows the same pattern, with the Arc B580 at 427.2 GTexel/s compared to 51.20 GTexel/s.

Memory architecture differs entirely. The Arc B580 uses 12 GB of GDDR6 on a 192-bit bus, delivering 456.0 GB/s of bandwidth. The Ryzen Z2 A GPU uses 16 GB of LPDDR5 on a 128-bit bus, delivering 102.4 GB/s. The Arc B580 has more than four times the bandwidth despite having less capacity. Clock behavior also diverges: the Arc B580 runs at a fixed 2670 MHz for both base and boost, while the Ryzen Z2 A GPU runs at 1000 MHz base and 1600 MHz boost. Memory clocks show the same gap, with the Arc B580 at 2375 MHz (19 Gbps effective) versus 800 MHz (6.4 Gbps effective) for the Ryzen Z2 A GPU. The Arc B580 also lists a dual-slot form factor, a single 8-pin power connector, a 450 W suggested PSU, and PCIe 4.0 x8 interface. The Ryzen Z2 A GPU lists no slot width, no power connectors, no suggested PSU, and no bus interface. Display outputs differ as well: the Arc B580 provides one HDMI 2.1a and three DisplayPort 2.1 outputs, while the Ryzen Z2 A GPU provides a single USB Type-C output.

Head-to-Head Benchmarks

The head-to-head benchmark array between these two GPUs is empty. No direct comparative tests exist in the database. The Intel Arc B580, however, has a complete record of individual benchmark results, while the AMD Ryzen Z2 A GPU has none. The Arc B580's strongest recorded result is in Geekbench Vulkan, where it scores 109672. Its Geekbench OpenCL score is 92821. In Passmark tests, the Arc B580 scores 15748 in G3D, 7729 in GPU compute, 709 in G2D, 183 in DirectX 9, 128 in DirectX 11, 76 in DirectX 10, and 76 in DirectX 12. In 3DMark Steel Nomad DX12, it scores 3068.

The absence of any recorded benchmarks for the Ryzen Z2 A GPU means no direct comparison can be made from the database. The closest available reference points are the Arc B580's nearest rivals. The data shows the Arc B580 performing within a narrow band around these rivals: it is 0.2% behind the AMD Radeon RX 580 2048SP, 0.6% ahead of the NVIDIA GeForce RTX 2080, 0.7% behind the NVIDIA GeForce RTX 3080, and 1% behind the NVIDIA P106-100. This places the Arc B580 in a performance tier where a single percentage point separates it from several well-known desktop GPUs.

The FP32 compute gap between the two parts provides a theoretical comparison. The Arc B580 delivers 13.67 TFLOPS, which is roughly 8.3 times the 1.638 TFLOPS of the Ryzen Z2 A GPU. Memory bandwidth shows a similar ratio, with the Arc B580 at 456.0 GB/s versus 102.4 GB/s, a 4.45 times advantage. Pixel rate favors the Arc B580 by a factor of 8.34, and texture rate favors it by a factor of 8.34. These ratios come from the recorded specification fields, not from benchmark scores, since the Ryzen Z2 A GPU has no benchmark entries.

Where Each One Wins

The Intel Arc B580 wins in every category where data exists. Its recorded benchmarks span multiple APIs and workloads, including DirectX 9, DirectX 10, DirectX 11, DirectX 12, OpenCL, Vulkan, and 3DMark Steel Nomad. The Ryzen Z2 A GPU has no recorded wins in any benchmark category because no benchmark data exists for it. The Arc B580 also wins on compute throughput, memory bandwidth, pixel fill, texture fill, ray tracing core count, and clock speed.

The AMD Ryzen Z2 A GPU wins only in areas that do not require benchmark validation. It has a higher memory capacity at 16 GB versus 12 GB, a lower TDP at 15 W versus 190 W, and a smaller die at 163 mm² versus 272 mm². It also uses LPDDR5 memory, which typically indicates a power-optimized design, and it outputs video through a single USB Type-C connection, suggesting integration into a compact or portable device. The Arc B580, by contrast, is a dual-slot desktop card with a 272 mm length, 115 mm height, and 45 mm width, requiring a 450 W PSU.

The data implies a use-case split based on power and form factor. The Ryzen Z2 A GPU appears suited for low-power environments where its 15 W TDP and compact footprint matter more than raw throughput. The Arc B580 appears suited for desktop gaming and compute workloads where its 13.67 TFLOPS, 456.0 GB/s bandwidth, and 68th percentile ranking provide measurable performance. The Arc B580's nearest rival data reinforces this: it trades blows with the RX 580 2048SP, RTX 2080, RTX 3080, and P106-100, all of which are desktop-class parts. The Ryzen Z2 A GPU has no such reference points in the database, leaving its performance unquantified. For any workload requiring verifiable graphics output, the Arc B580 is the only part with recorded evidence. For any workload prioritizing minimal power draw and a small physical footprint, the Ryzen Z2 A GPU offers the lower TDP and smaller die, but without benchmark confirmation of its capability.
