Architecture Differences

The AMD Ryzen Z2 GPU is built on the RDNA 3.0 architecture using the Hawk Point chip, classified as a Console GPU generation. It uses a 4 nm TSMC process with 25,390 million transistors packed into a 178 mm² die, yielding a transistor density of 142.6M per mm². The GPU operates with a base clock of 800 MHz and a boost clock of 2700 MHz. Its memory subsystem consists of 16 GB of LPDDR5X on a 128-bit bus, running at 937 MHz with 7.5 Gbps effective speed, producing 119.9 GB/s of bandwidth. The compute layout includes 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The FP16 throughput matches FP32 at 8.294 TFLOPS, indicating a 1:1 ratio. The chip draws 28 W and uses no external power connectors, with a single USB Type-C display output.

The Intel Arc B570 is built on the Xe2-HPG architecture using the BMG-G21 chip, part of the Battlemage generation (Arc 5). It uses a 5 nm TSMC process with 19,600 million transistors on a 272 mm² die, resulting in a transistor density of 72.1M per mm². The GPU runs at a fixed 2500 MHz clock for both base and boost. Memory consists of 10 GB of GDDR6 on a 160-bit bus, running at 2375 MHz with 19 Gbps effective speed, producing 380.0 GB/s of bandwidth. The compute layout includes 2304 shading units, 144 TMUs, 80 ROPs, and 18 ray tracing cores. FP16 throughput is 23.04 TFLOPS at a 2:1 ratio relative to FP32, indicating doubled half-precision performance. The card draws 150 W, uses a dual-slot cooler with one 8-pin power connector, and the database suggests a 450 W power supply. It connects via PCIe 4.0 x8 and outputs through one HDMI 2.1a and three DisplayPort 2.1 connectors. Its predecessor is Alchemist.

The architectural differences are stark. The Ryzen Z2 GPU uses a newer 4 nm node with higher transistor density, enabling a much lower power envelope. The Arc B570 uses a larger die with more compute units, higher clocks, and a wider memory interface, but at the cost of over five times the power draw. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 GPU and the Intel Arc B570. The Ryzen Z2 GPU has no recorded benchmark scores, while the Arc B570 has ten benchmark entries. Therefore, the analysis relies on the Arc B570's absolute scores and its position against nearest rivals.

The Arc B570's average benchmark score is 20556. Its nearest rivals are the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534 (0.1% behind), the Intel Arc A750 with 20582 (0.1% ahead), the NVIDIA Quadro M4000M with 20480 (0.4% behind), and the AMD Radeon R9 M390X with 20662 (0.5% ahead). The delta percentages are all within 0.5%, indicating that the Arc B570 sits in a tightly clustered performance tier where minor test variance determines rank.

Looking at individual Arc B570 benchmark results, the highest score comes from Geekbench Vulkan at 96844, followed by Geekbench OpenCL at 83514. Passmark GPU Compute shows 7281, while Passmark G3D delivers 14195. The DirectX tests show Passmark DX11 at 118, DX9 at 164, DX12 at 72, and DX10 at 65. The Passmark G2D score is 661. These scores place the Arc B570 in the 65th percentile among all GPUs, which is above the Ryzen Z2 GPU's 50th percentile ranking.

Since the Ryzen Z2 GPU lacks benchmark scores, its performance can only be estimated from its specifications. The 8.294 TFLOPS FP32 rate is 28% lower than the Arc B570's 11.52 TFLOPS. The memory bandwidth gap is larger: 119.9 GB/s versus 380.0 GB/s, a 68% deficit for the AMD part. The Ryzen Z2 GPU has one-third the shading units (768 versus 2304), one-third the TMUs (48 versus 144), and 40% of the ROPs (32 versus 80). The Arc B570 also has 50% more ray tracing cores (18 versus 12).

Where Each One Wins

The Intel Arc B570 wins in every measurable performance category. Its FP32 throughput is 8.294 TFLOPS higher, its pixel rate is 200.0 GPixel/s versus 86.40 GPixel/s, and its texture rate is 360.0 GTexel/s versus 129.6 GTexel/s. In memory bandwidth, the Arc B570 delivers 380.0 GB/s, which is 260.1 GB/s more than the Ryzen Z2 GPU. This bandwidth advantage is critical for high-resolution textures, large frame buffers, and compute workloads that move substantial data. The Arc B570's 10 GB GDDR6 memory, while smaller in capacity than the Ryzen Z2 GPU's 16 GB LPDDR5X, offers much higher throughput and a dedicated memory bus.

The Arc B570 also wins on display connectivity. It offers one HDMI 2.1a and three DisplayPort 2.1 outputs, enabling multi-monitor setups, while the Ryzen Z2 GPU offers only one USB Type-C output. The Arc B570's dual-slot design with a 272 mm length and 115 mm height indicates a substantial cooling solution appropriate for sustained desktop workloads. Its predecessor, Alchemist, shows a lineage of discrete GPU development.

The AMD Ryzen Z2 GPU wins in power efficiency and integration. Its 28 W TDP is 122 W lower than the Arc B570's 150 W TDP. It requires no power connectors and no suggested PSU, whereas the Arc B570 needs one 8-pin connector and a 450 W power supply. The Ryzen Z2 GPU uses a 4 nm process with 25,390 million transistors on a 178 mm² die, achieving a transistor density of 142.6M per mm², nearly double the Arc B570's 72.1M per mm². This density enables the AMD part to deliver 8.294 TFLOPS within a 28 W envelope. The 16 GB LPDDR5X memory provides twice the capacity of the Arc B570, which benefits workloads that require large working sets but tolerate lower bandwidth, such as certain AI inference tasks or data-parallel kernels with moderate data movement.

The Ryzen Z2 GPU is a console-class part, meaning it is designed for embedded or handheld systems where power draw and physical footprint are paramount. Its single USB Type-C display output aligns with portable or compact device use cases. The Arc B570 is a desktop add-in card with a fixed clock of 2500 MHz, a stable performance profile, and a 65th percentile standing among all GPUs. The Ryzen Z2 GPU's 50th percentile standing, combined with no benchmark scores, indicates it targets a different performance envelope.

For users building a desktop gaming PC or workstation, the Arc B570 is the clear choice based on the recorded benchmark scores and specifications. For users designing a low-power embedded system or handheld console, the Ryzen Z2 GPU offers superior efficiency and memory capacity in a much smaller power budget. The data confirms that these are complementary products rather than direct competitors.
