AMD Ryzen Z2 GPU vs Intel Arc Pro B70 Comparison

Where Each One Wins

The recorded data separates these two GPUs into entirely different performance classes. The AMD Ryzen Z2 GPU is a 28 W integrated-style part, while the Intel Arc Pro B70 is a 230 W dual-slot add-in card with a PCIe 5.0 x16 interface. In every measurable compute category, the Intel part holds the advantage. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 throughput against 8.294 TFLOPS for the Ryzen Z2 GPU, which is a 2.77x margin. Pixel fill rate favors Intel at 358.4 GPixel/s versus 86.40 GPixel/s, a 4.15x difference. Texture rate tells a similar story: 716.8 GTexel/s versus 129.6 GTexel/s, or 5.53x in favor of the Arc Pro B70.

The AMD part does not win any benchmark category in the database. Its strengths lie in power efficiency and physical footprint, not raw throughput. The Ryzen Z2 GPU draws 28 W, which is a fraction of the Arc Pro B70’s 230 W envelope. That allows the AMD part to operate without any power connectors, whereas the Intel card requires a single 8-pin connector and a 550 W suggested power supply. The Ryzen Z2 GPU also measures nothing in terms of slot width, while the Arc Pro B70 occupies a dual-slot form factor at 267 mm in length.

Memory capacity and bandwidth both go to Intel as well. The Arc Pro B70 ships with 32 GB of GDDR6 across a 256-bit bus, yielding 608.0 GB/s of bandwidth. The Ryzen Z2 GPU has 16 GB of LPDDR5X on a 128-bit bus, producing 119.9 GB/s. That is a 5.07x bandwidth advantage for Intel. The FP16 comparison is even starker: the Arc Pro B70 reaches 45.88 TFLOPS with a 2:1 ratio, while the Ryzen Z2 GPU caps at 8.294 TFLOPS with a 1:1 ratio.

For use-case segmentation, the data points to the Arc Pro B70 as the choice for large memory workloads, high-resolution rendering, and compute-heavy tasks. The Ryzen Z2 GPU is suited to low-power embedded or handheld scenarios where 28 W and a single USB Type-C display output are acceptable constraints.

Architecture Differences

The two GPUs come from different architectural lineages. AMD uses RDNA 3.0 on the Hawk Point chip, fabricated on a 4 nm TSMC process. Intel employs Xe2-HPG on the BMG-G31 chip, part of the Battlemage Pro Series, built on a 5 nm TSMC process. The die sizes diverge substantially: the Ryzen Z2 GPU measures 178 mm² with 25,390 million transistors, while the Arc Pro B70 spans 368 mm² with an unknown transistor count. Transistor density for the AMD part is 142.6M per mm²; Intel’s density figure is not recorded.

Compute unit counts follow the performance split. The Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The Arc Pro B70 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Intel part also has no tensor core field recorded, matching the AMD part in that regard. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Clock behavior differs in key ways. The Ryzen Z2 GPU runs a base clock of 800 MHz and a boost clock of 2700 MHz. The Arc Pro B70 starts at 2280 MHz base and boosts to 2800 MHz. Memory clocks also diverge: AMD uses 937 MHz with 7.5 Gbps effective, while Intel runs 2375 MHz with 19 Gbps effective. These clock differences compound the architectural gap, pushing the Intel part further ahead in every throughput metric.

The power delivery architecture is fundamentally different. The Ryzen Z2 GPU requires no external power connectors, consistent with its 28 W TDP. The Arc Pro B70 needs one 8-pin connector and a 550 W suggested PSU. Display outputs also differ: the AMD part exposes a single USB Type-C port, while the Intel card provides one HDMI 2.1a and three DisplayPort 2.1 outputs. The Intel card has measurable dimensions of 267 mm by 110 mm by 39 mm; the AMD part has no recorded physical dimensions.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark records between these two products. The wins counters show zero for both sides, and the headToHeadBenchmarks array is empty. However, the underlying specification data permits a direct comparison of every recorded performance metric.

FP32 throughput is the clearest differentiator. The Arc Pro B70 delivers 22.94 TFLOPS, which is 2.77x the Ryzen Z2 GPU’s 8.294 TFLOPS. In FP16 compute, the Intel part reaches 45.88 TFLOPS, a 5.53x margin over AMD’s 8.294 TFLOPS, because Intel’s architecture doubles FP16 throughput while AMD runs a 1:1 ratio.

Pixel throughput favors Intel by 4.15x, with 358.4 GPixel/s versus 86.40 GPixel/s. Texture throughput shows the largest relative gap at 5.53x, with 716.8 GTexel/s from Intel against 129.6 GTexel/s from AMD. Memory bandwidth is the second-largest relative gap: 608.0 GB/s versus 119.9 GB/s, a 5.07x difference. The Arc Pro B70 also doubles memory capacity from 16 GB to 32 GB and doubles the bus width from 128-bit to 256-bit.

Clock speeds tell a nuanced story. The Intel base clock of 2280 MHz is 2.85x higher than AMD’s 800 MHz base. The boost clock gap is smaller: 2800 MHz versus 2700 MHz, only a 1.04x difference. This suggests the Ryzen Z2 GPU’s boost behavior is competitive in frequency terms, but the massive difference in shading units, TMUs, and ROPs renders that clock parity irrelevant for throughput.

The ray tracing core count also favors Intel at 32 cores versus 12 cores, a 2.67x margin. Both parts support DirectX 12 Ultimate, so ray tracing workloads are available on both, but the hardware capacity differs sharply.

The Verdict

The data indicates a complete class separation. The Intel Arc Pro B70 is a high-power workstation or desktop part with 32 GB of memory, 608.0 GB/s of bandwidth, and 22.94 TFLOPS of FP32 compute. It occupies a dual-slot form factor, requires a 550 W PSU, and targets applications that demand large memory pools and high throughput. The AMD Ryzen Z2 GPU is a low-power integrated solution at 28 W with 16 GB of slower LPDDR5X memory and 8.294 TFLOPS of FP32 compute. Its single USB Type-C output and lack of power connectors position it for compact or mobile systems.

The launch MSRP of the Arc Pro B70 is 949 USD. The Ryzen Z2 GPU has no recorded launch MSRP.

The benchmark data shows no scenario where the AMD part wins on raw performance. Every recorded metric favors Intel: FP32, FP16, pixel rate, texture rate, memory bandwidth, memory capacity, shading units, TMUs, ROPs, and ray tracing cores. The Ryzen Z2 GPU’s advantages are limited to power draw, physical footprint, and the absence of a required power supply.

For compute-heavy workloads, large model inference, or high-resolution rendering, the Arc Pro B70 is the only viable option from the recorded data. For ultra-low-power deployments where the 28 W envelope is the binding constraint, the Ryzen Z2 GPU fits where the Intel card cannot operate. The choice reduces to power budget versus performance budget, and the data leaves no ambiguity about which part wins each category.
