AMD Ryzen Z2 Go GPU vs Intel Arc Pro B70 Comparison

The AMD Ryzen Z2 Go GPU and the Intel Arc Pro B70 occupy opposite ends of the graphics hardware spectrum, as recorded in the database. The Z2 Go is a 28 W console-class part built for efficiency, while the Arc Pro B70 is a 230 W professional workstation card with a dual-slot cooler. Their specifications, architectures, and intended workloads diverge sharply, and the data supports only one conclusion for raw performance: the Intel part dominates. However, the AMD part has its own niche in low-power systems. This analysis draws exclusively on the recorded specifications for both units.

Head-to-Head Benchmarks

The database lists no direct benchmark scores for either GPU, so the comparison must rely on the recorded raw throughput figures. The Intel Arc Pro B70 delivers 22.94 TFLOPS of FP32 compute, which is 5.53 times the 4.147 TFLOPS of the AMD Ryzen Z2 Go GPU. In FP16 with the 2:1 ratio, Intel reaches 45.88 TFLOPS versus AMD's 8.294 TFLOPS, a 5.53x advantage as well. These numbers indicate that the Arc Pro B70 handles compute-heavy workloads with a massive margin over the Z2 Go.

Pixel throughput tells a similar story. The Intel part records 358.4 GPixel/s, while the AMD part manages 86.40 GPixel/s. That is a 4.15x difference. Texture rate follows: Intel posts 716.8 GTexel/s against AMD's 129.6 GTexel/s, a 5.53x gap. Every measured throughput metric in the database favors Intel by at least four times, and in most cases by over five times.

Memory bandwidth is another decisive split. The Arc Pro B70 has 608.0 GB/s of bandwidth from its 256-bit GDDR6 interface. The Z2 Go has 102.4 GB/s from a 128-bit LPDDR5 bus. That is a 5.94x advantage for Intel. For texture-heavy rendering or large data sets, the bandwidth gap compounds the compute gap.

Clock speeds also favor Intel, though the architectures differ. The Arc Pro B70 has a base clock of 2280 MHz and a boost of 2800 MHz. The Z2 Go has a base of 800 MHz and a boost of 2700 MHz. The base clock difference is stark: Intel runs nearly three times higher at idle-adjacent loads. The boost clocks are closer, with Intel ahead by 100 MHz, but the Z2 Go's lower base suggests it downclocks aggressively to fit its 28 W envelope.

The shading resources are not comparable in count. Intel has 4096 shading units, 256 TMUs, and 128 ROPs. AMD has 768 shading units, 48 TMUs, and 32 ROPs. Intel has 5.33x the shading units, 5.33x the TMUs, and 4x the ROPs. Ray tracing cores follow the same pattern: Intel has 32, AMD has 12, a 2.67x difference. These are architectural resources, not benchmark scores, but they explain the throughput ratios.

The percentile ranking for both GPUs is 50, and the average benchmark score for both is 0, which means the database has no recorded workload results for either part. Without measured game or application benchmarks, the FP32, pixel, texture, and bandwidth figures serve as the only quantitative basis for comparison. On those grounds, the Arc Pro B70 is the clear performer, with a 5.53x compute lead, a 5.94x bandwidth lead, and a 4.15x pixel rate lead.

Architecture Differences

The two GPUs use completely different underlying designs. The AMD Ryzen Z2 Go GPU is built on the Rembrandt+ chip with RDNA 2.0 architecture, categorized in the database as a Console GPU from AMD. The Intel Arc Pro B70 uses the BMG-G31 chip with Xe2-HPG architecture, part of the Battlemage Pro Series. These are not iterative rivals; they are separate design philosophies.

Manufacturing process separates them further. The Z2 Go uses a 6 nm process at TSMC. The Arc Pro B70 uses a 5 nm process, also at TSMC. The smaller node gives Intel a density and power efficiency advantage at the transistor level, though the die sizes tell a complex story. Intel's die measures 368 mm², while AMD's is 208 mm². Transistor counts are only recorded for AMD: 13,100 million transistors on the Z2 Go, giving a density of 63.0 million transistors per mm². Intel's transistor count is listed as unknown, so density cannot be calculated for the Arc Pro B70.

Memory architecture is a core differentiator. The Z2 Go uses 16 GB of LPDDR5 on a 128-bit bus, with memory clocks of 800 MHz and an effective data rate of 6.4 Gbps. Bandwidth is 102.4 GB/s. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus, with memory clocks of 2375 MHz and an effective rate of 19 Gbps. Bandwidth reaches 608.0 GB/s. The Intel part has twice the memory capacity and nearly six times the bandwidth. The memory type difference also matters: GDDR6 is dedicated graphics memory, while LPDDR5 in this context is shared with the system in a console-style design.

Power delivery defines their operational envelopes. The Z2 Go has a TDP of 28 W and requires no power connectors. The Arc Pro B70 has a TDP of 230 W, uses a single 8-pin power connector, and the database lists a suggested PSU of 550 W. The 8.21x power difference explains most of the performance gap. The Intel card also has a dual-slot cooler and physical dimensions of 267 mm in length, 110 mm in height, and 39 mm in width, while the Z2 Go has no recorded dimensions, slot width, or bus interface.

Feature sets for display output differ. The Z2 Go has a single USB Type-C output. The Arc Pro B70 has 1x HDMI 2.1a and 3x DisplayPort 2.1. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The bus interface is only recorded for Intel: PCIe 5.0 x16. The Z2 Go's bus interface is not listed.

Release timing is also distinct. The Z2 Go has a release date of 2024-12-31, while the Arc Pro B70 is dated 2026-03-25. The production status for the AMD part is listed as Active, while Intel's production status is not recorded. The Intel part has a launch MSRP of 949 USD, stated once here as recorded.

The Verdict

The data points to a simple split. For any workload that depends on raw compute, memory bandwidth, or pixel throughput, the Intel Arc Pro B70 is the only viable choice. Its FP32 output of 22.94 TFLOPS is 5.53x the Z2 Go's 4.147 TFLOPS. Its bandwidth of 608.0 GB/s is 5.94x higher. Its pixel rate of 358.4 GPixel/s is 4.15x higher. These are not minor margins; they are dominant across every recorded metric.

The AMD Ryzen Z2 Go GPU serves a different purpose entirely. At 28 W with no power connectors, it fits into compact, low-power systems where a 230 W dual-slot card with a 550 W suggested PSU is physically and electrically impossible. The Z2 Go's 16 GB of LPDDR5 memory and 102.4 GB/s bandwidth are adequate for its target console-class workloads, and its 4.147 TFLOPS of FP32 is respectable for its power class. It also has a single USB Type-C output, suggesting a simple, integrated form factor.

The Arc Pro B70 targets professional or high-end workstation use. Its 32 GB of GDDR6 memory, 256-bit bus, and 608.0 GB/s bandwidth suit large datasets, while its 32 ray tracing cores and 4096 shading units provide substantial compute headroom. The database records a launch MSRP of 949 USD for this card, which positions it as a premium part. The Z2 Go has no recorded launch MSRP.

There is no scenario in the recorded data where the Z2 Go outperforms the Arc Pro B70. The wins for AMD are limited to power consumption, physical size, and simplicity: 28 W versus 230 W, no power connectors, and a single USB Type-C output. For users constrained by power or space, the Z2 Go is the functional choice. For everyone else, the Arc Pro B70's 5.53x compute, 5.94x bandwidth, and 4.15x pixel rate advantages are decisive.
