AMD Ryzen Z1 Extreme GPU vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Ryzen Z1 Extreme GPU against the Intel Arc Pro B70. Neither product has an average benchmark score listed, and both sit at the 50th percentile among all GPUs in the database. Consequently, there are no measured wins for either side, no performance deltas, and no comparative scoring data to walk through. The absence of benchmark results means the analysis below relies entirely on the documented architectural specifications and memory subsystem data, not on empirical testing outcomes.

The AMD Ryzen Z1 Extreme GPU presents a compact, low-power design. Its compute configuration includes 768 shading units, 48 texture mapping units, and 32 render output units. The chip operates with a base clock of 800 MHz and a boost clock of 2700 MHz. Peak FP32 throughput is recorded at 8.294 TFLOPS, while FP16 reaches 16.59 TFLOPS with a 2:1 ratio. The pixel rate is 86.40 GPixel/s, and the texture rate is 129.6 GTexel/s. Memory capacity is 16 GB of LPDDR5, connected across a 64-bit bus, yielding 51.20 GB/s of bandwidth. The memory clock is listed at 800 MHz with 6.4 Gbps effective speed.

The Intel Arc Pro B70 uses a substantially larger configuration. It has 4096 shading units, 256 texture mapping units, and 128 render output units. Base clock is 2280 MHz, boost clock is 2800 MHz. FP32 performance is recorded at 22.94 TFLOPS, FP16 at 45.88 TFLOPS (2:1). Pixel rate reaches 358.4 GPixel/s, and texture rate is 716.8 GTexel/s. Memory is 32 GB of GDDR6 on a 256-bit bus, providing 608.0 GB/s of bandwidth. Memory clock is 2375 MHz with 19 Gbps effective speed.

Given the lack of measured scores, the comparison must be framed through these specification differences. The Arc Pro B70 delivers roughly 2.77 times the FP32 throughput of the Ryzen Z1 Extreme GPU (22.94 TFLOPS versus 8.294 TFLOPS). Its memory bandwidth is approximately 11.87 times higher (608.0 GB/s versus 51.20 GB/s). The pixel rate advantage is about 4.15 times (358.4 GPixel/s versus 86.40 GPixel/s), and texture rate is roughly 5.53 times higher (716.8 GTexel/s versus 129.6 GTexel/s). These are raw hardware capabilities, not validated performance results, so the data indicates a clear theoretical margin for the Intel part in compute-heavy and bandwidth-sensitive workloads.

The Ryzen Z1 Extreme GPU has a 30 W TDP, while the Arc Pro B70 has a 230 W TDP. The power draw difference is substantial, but the database does not include any efficiency measurements or power-normalized benchmark scores. Therefore, no conclusion about performance per watt can be drawn from the recorded facts.

The Verdict

The data indicates that neither product has a measured benchmark advantage over the other in the database. Both have zero wins in head-to-head comparisons, zero average benchmark scores, and identical 50th percentile rankings. The verdict from a strict database perspective is that these two GPUs cannot be ranked against each other based on empirical results, because no results exist.

From a specification standpoint, the Intel Arc Pro B70 is positioned as a higher-throughput, higher-bandwidth device. Its memory capacity is double that of the AMD part (32 GB versus 16 GB), its bus width is four times larger (256-bit versus 64-bit), and its bandwidth is over an order of magnitude higher. The AMD Ryzen Z1 Extreme GPU, in contrast, is a 30 W part with a small 178 mm² die on a 4 nm process, built on the RDNA 3.0 architecture. The Intel chip uses a 368 mm² die on a 5 nm process, based on the Xe2-HPG architecture.

The database records the launch MSRP for the AMD Ryzen Z1 Extreme GPU as 699 USD, and for the Intel Arc Pro B70 as 949 USD. These are the only price-related facts available. No performance-per-dollar calculations can be made, as there are no benchmark scores to divide by.

For a user choosing strictly from the recorded data, the Intel Arc Pro B70 offers higher raw compute, more memory, and wider memory bandwidth, but at a higher TDP and a higher launch MSRP. The AMD Ryzen Z1 Extreme GPU offers a lower TDP, a smaller physical footprint (280 mm length, 111 mm height, 21 mm width versus 267 mm, 110 mm, 39 mm), and a lower launch MSRP. The Arc Pro B70 is dual-slot with a single 8-pin power connector and a suggested power supply of 550 W; the AMD part has no power connectors and no suggested PSU rating.

Where Each One Wins

The database does not provide any measured benchmark wins for either GPU. The wins matrix shows zero wins for both sides. Therefore, a use-case split must be inferred from the architectural and memory specifications, not from performance tests.

The AMD Ryzen Z1 Extreme GPU, with a 30 W TDP and no power connectors, is suited to scenarios where power draw and physical space are constrained. Its 178 mm² die and 4 nm process suggest a focus on integration efficiency. The memory configuration, 16 GB LPDDR5 at 51.20 GB/s, is modest by comparison. The display output is a single USB Type-C port. This part appears designed for compact or mobile-style deployments, though the database does not specify an intended form factor.

The Intel Arc Pro B70, with a 230 W TDP, a dual-slot cooler, and an 8-pin power connector, is suited to desktop configurations with a 550 W suggested power supply. Its 32 GB GDDR6 memory and 608.0 GB/s bandwidth indicate a capacity for large datasets and memory-intensive workloads. The 4096 shading units and 32 ray tracing cores suggest capability in rendering and compute tasks. Display outputs include one HDMI 2.1a and three DisplayPort 2.1 connections, supporting multi-display setups. The PCIe 5.0 x16 interface provides a high-bandwidth host connection, whereas the AMD part has no recorded bus interface.

The AMD part's FP16 throughput of 16.59 TFLOPS is higher than its FP32 rate due to the 2:1 ratio, which is typical for RDNA 3.0. The Intel part shows the same 2:1 FP16 ratio, reaching 45.88 TFLOPS. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature compatibility is identical per the database.

For workloads that depend on raw throughput, memory bandwidth, or memory capacity, the Intel Arc Pro B70 is the only choice based on the data. For workloads that require minimal power draw, no external power connectors, and a smaller physical footprint, the AMD Ryzen Z1 Extreme GPU is the only option. There is no overlap in these categories, so the use-case split is clear from specifications alone.
