Architecture Differences

The AMD Ryzen Z2 Go GPU is built on RDNA 2.0, a mature architecture used in console-class parts, fabricated on a 6 nm TSMC process. The chip, codenamed Rembrandt+, integrates 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0 million per mm². It is classified as a Console GPU (AMD) generation part. The Intel Arc B570, by contrast, uses the newer Xe2-HPG architecture from the Battlemage (Arc 5) generation. Its BMG-G21 chip is manufactured on a 5 nm TSMC process with 19,600 million transistors on a 272 mm² die, giving a higher transistor density of 72.1 million per mm².

Shader resources differ substantially. The AMD part has 768 shading units, 48 texture mapping units, 32 raster operation units, and 12 ray tracing cores. The Intel Arc B570 packs 2304 shading units, 144 TMUs, 80 ROPs, and 18 ray tracing cores. This is a 3x advantage in shading units and TMUs, and a 2.5x advantage in ROPs. The AMD GPU does not list tensor cores, and neither does the Intel part, so AI acceleration is not a differentiator in the recorded data.

Clock behavior also diverges. The AMD GPU has a base clock of 800 MHz and a boost of 2700 MHz, while the Intel GPU runs at a flat 2500 MHz for both base and boost. The memory clock differs as well: the AMD uses 800 MHz (6.4 Gbps effective) LPDDR5, while the Intel uses 2375 MHz (19 Gbps effective) GDDR6. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical on paper.

The Intel card is a dual-slot, 272 mm long, 115 mm tall PCIe 4.0 x8 add-in board with display outputs including 1x HDMI 2.1a and 3x DisplayPort 2.1. The AMD GPU, however, has no slot width, no bus interface listed, and only a single USB Type-C display output. Power delivery also differs: the AMD part is a 28 W chip with no external power connectors, while the Intel part is a 150 W card requiring one 8-pin connector.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in power efficiency and portability scenarios. Its 28 W TDP, absence of power connectors, and single USB Type-C output indicate a design aimed at compact, low-power systems where thermal and electrical budgets are tight. Its 16 GB of LPDDR5 memory provides a capacity advantage for workloads that need large frame buffers, even if the bandwidth is modest at 102.4 GB/s. The higher boost clock of 2700 MHz suggests the architecture can scale frequency when thermals allow.

The Intel Arc B570 wins decisively in raw compute and rendering throughput. Its 11.52 TFLOPS FP32 output, 380.0 GB/s memory bandwidth, and 200.0 GPixel/s pixel rate place it in a different performance class. The 2304 shading units and 144 TMUs allow it to handle high-resolution textures and complex geometry far more effectively than the 768 shading units and 48 TMUs of the AMD part. The Intel card also has more ray tracing cores (18 vs 12), which should improve ray-traced workloads.

In the benchmark database, the Intel Arc B570 has a recorded average benchmark score of 20556, while the AMD Ryzen Z2 Go GPU has no recorded benchmark scores and an average score of 0. The Intel part sits at the 65th percentile versus the AMD part's 50th percentile. The Intel card also has a full suite of PassMark and Geekbench results, while the AMD part has none in the database.

Specification Differences

The two GPUs differ across nearly every specification field. The AMD Ryzen Z2 Go GPU uses a 6 nm process, 13,100 million transistors on a 208 mm² die, with a density of 63.0M / mm². The Intel Arc B570 uses a 5 nm process, 19,600 million transistors on a 272 mm² die, with a density of 72.1M / mm². Base clocks are 800 MHz versus 2500 MHz, and boost clocks are 2700 MHz versus 2500 MHz. Memory size is 16 GB LPDDR5 versus 10 GB GDDR6, with bus widths of 128 bit versus 160 bit, and bandwidth of 102.4 GB/s versus 380.0 GB/s.

Compute resources show 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores for AMD, versus 2304 shading units, 144 TMUs, 80 ROPs, and 18 RT cores for Intel. Pixel rate is 86.40 GPixel/s versus 200.0 GPixel/s, and texture rate is 129.6 GTexel/s versus 360.0 GTexel/s. FP32 is 4.147 TFLOPS versus 11.52 TFLOPS, and FP16 is 8.294 TFLOPS versus 23.04 TFLOPS. TDP is 28 W versus 150 W. The Intel card has a dual-slot form factor, a 1x 8-pin power connector, a suggested 450 W PSU, and PCIe 4.0 x8 interface, while the AMD part has none of those listed. Display outputs are 1x USB Type-C for AMD versus 1x HDMI 2.1a and 3x DisplayPort 2.1 for Intel.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 Go GPU and the Intel Arc B570. However, the Intel Arc B570 has a substantial set of individual benchmark scores that can be examined. In 3DMark Steel Nomad DX12, the Intel card scores 2649. Geekbench results show 83514 in OpenCL and 96844 in Vulkan. PassMark scores include 65 in DirectX 10, 118 in DirectX 11, 72 in DirectX 12, 164 in DirectX 9, 661 in G2D, 14195 in G3D, and 7281 in GPU compute.

The Intel Arc B570's average benchmark score of 20556 places it in close competition with several rivals. The nearest rival is the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534, a delta of 0.1 percent. The Intel Arc A750 scores 20582, which is 0.1 percent higher than the B570. The NVIDIA Quadro M4000M scores 20480, a 0.4 percent difference, and the AMD Radeon R9 M390X scores 20662, which is 0.5 percent higher. These tight deltas indicate that the B570 sits within a narrow performance band around these mobile and older desktop parts.

For the AMD Ryzen Z2 Go GPU, the absence of benchmark scores means no direct numerical comparison is possible from the recorded data. The only performance indicators are the computed rates: 86.40 GPixel/s, 129.6 GTexel/s, 4.147 TFLOPS FP32, and 8.294 TFLOPS FP16. These are approximately 43 percent of the Intel card's pixel rate, 36 percent of its texture rate, 36 percent of its FP32, and 36 percent of its FP16. The Intel card's 380.0 GB/s memory bandwidth is 3.7 times the AMD part's 102.4 GB/s.

The Verdict

The recorded data shows two GPUs built for entirely different roles. The AMD Ryzen Z2 Go GPU is a low-power, high-capacity part with 16 GB of memory and a 28 W TDP. Its 50th percentile ranking and lack of any benchmark scores in the database suggest it is not intended for high-throughput rendering. Its 4.147 TFLOPS FP32 and 102.4 GB/s bandwidth are sufficient for light workloads, but the single USB Type-C output and no power connectors limit its deployment to systems where space and power are primary constraints.

The Intel Arc B570, on the other hand, is a full-sized add-in card with a 150 W TDP, dual-slot cooler, and 8-pin power connector. Its 11.52 TFLOPS FP32, 380.0 GB/s bandwidth, and 200.0 GPixel/s pixel rate are roughly 2.8x, 3.7x, and 2.3x the AMD part's respective figures. Its 65th percentile ranking and average score of 20556 place it in the same performance class as the NVIDIA GeForce RTX 3070 Mobile and the Intel Arc A750, with deltas under 0.5 percent. The 3DMark Steel Nomad score of 2649 and PassMark G3D score of 14195 confirm solid DirectX 12 and general 3D performance.

For users selecting a GPU strictly from the database, the Intel Arc B570 is the choice for any compute-intensive or high-resolution gaming workload. The AMD Ryzen Z2 Go GPU is the only option if the requirement is a 28 W part with 16 GB of memory and no external power connectors. The data does not support any other conclusion: the Intel card dominates in every measured performance metric, while the AMD part wins only in power draw, memory capacity, and physical simplicity.
