Architecture Differences

The AMD Ryzen Z1 GPU and Intel Arc Pro B370 represent two fundamentally different design approaches within the mobile and integrated graphics space. The AMD part is a Phoenix chip using RDNA 3.0 architecture, fabricated on a 4 nm process at TSMC. It contains 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The Intel Arc Pro B370 is a Panther Lake chip using Xe3-LPG architecture, fabricated on a 3 nm process at Intel. Its transistor count and die size are listed as unknown in the database.

The compute resources differ substantially. The AMD Ryzen Z1 GPU has 256 shading units, 16 texture mapping units, and 8 raster output pipelines. The Intel Arc Pro B370 has 1280 shading units, 40 TMUs, and 20 ROPs. That is a 5x difference in shading units, a 2.5x difference in TMUs, and a 2.5x difference in ROPs. Ray tracing cores also differ: the AMD part has 4, while the Intel part has 10.

Clock behavior separates the two as well. The AMD Ryzen Z1 GPU has a base clock of 1500 MHz and a boost clock of 2500 MHz. The Intel Arc Pro B370 has a much lower base clock of 300 MHz but a boost clock of 2400 MHz. The wide gap between base and boost on the Intel part suggests a power-adaptive design that scales up aggressively under load.

Memory architecture is another major divergence. The AMD Ryzen Z1 GPU uses dedicated 16 GB of LPDDR5 memory on a 64-bit bus, delivering 51.20 GB/s of bandwidth. Memory clock is 800 MHz with 6.4 Gbps effective. The Intel Arc Pro B370 relies entirely on system shared memory, with bus width and type both listed as system shared, and bandwidth described as system dependent. This means the Intel part's memory performance depends on the host platform's memory configuration.

Both processors support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD Ryzen Z1 GPU has no display outputs, while the Intel Arc Pro B370's display outputs are listed as portable device dependent. The power delivery situation is similar: both use no power connectors. The AMD part has a TDP of 30 W, while the Intel part has a TDP of 25 W.

Where Each One Wins

The benchmark data currently shows no wins for either processor in the head-to-head comparison, and both sit at the 50th percentile among all GPUs. However, the specification data provides a clear picture of where each design would dominate in practical use.

The Intel Arc Pro B370 wins on raw compute throughput. Its FP32 rating of 6.144 TFLOPS is more than double the AMD Ryzen Z1 GPU's 2.560 TFLOPS. The FP16 figures follow the same pattern: 12.29 TFLOPS for Intel versus 5.120 TFLOPS for AMD. The Intel part also has a decisive advantage in pixel throughput at 48.00 GPixel/s versus 20.00 GPixel/s, and in texture throughput at 96.00 GTexel/s versus 40.00 GTexel/s. These numbers indicate the Intel part is better suited for workloads that scale with shader count, texture sampling, and fill rate.

The AMD Ryzen Z1 GPU wins on clock speed and dedicated memory. Its boost clock of 2500 MHz exceeds the Intel part's 2400 MHz, and its base clock of 1500 MHz is five times higher than Intel's 300 MHz base. The dedicated 16 GB of LPDDR5 memory with a fixed 51.20 GB/s bandwidth provides predictable memory performance that does not depend on the host system. The Intel part's system shared memory could be faster or slower depending on the platform, but it introduces variability that the AMD part avoids.

The AMD Ryzen Z1 GPU also holds an advantage in physical integration details. It has defined dimensions of 280 mm length, 111 mm height, and 21 mm width. The Intel Arc Pro B370 is an IGP with no listed dimensions, indicating it is designed to be integrated into a processor package.

Head-to-Head Benchmarks

The database currently contains no recorded head-to-head benchmark runs between the AMD Ryzen Z1 GPU and the Intel Arc Pro B370. Both processors have an average benchmark score of 0 and no nearest rivals listed. The wins count is 0 for each side.

The absence of benchmark data means the comparison must rest on the specification-level measurements. The largest gaps in favor of the Intel Arc Pro B370 appear in compute throughput and fill rates. The FP32 difference is the most striking: 6.144 TFLOPS versus 2.560 TFLOPS, which places the Intel part 140% ahead in raw floating-point throughput. The FP16 comparison shows 12.29 TFLOPS versus 5.120 TFLOPS, a 140% advantage as well. Pixel rate favors Intel by 140% (48.00 GPixel/s versus 20.00 GPixel/s), and texture rate favors Intel by the same margin (96.00 GTexel/s versus 40.00 GTexel/s).

The resource count differences reinforce the throughput gap. The Intel part has 5 times the shading units, 2.5 times the TMUs, 2.5 times the ROPs, and 2.5 times the ray tracing cores of the AMD part. These structural advantages translate directly into the pixel, texture, and compute rate measurements recorded in the database.

The AMD Ryzen Z1 GPU holds advantages in clock speeds and memory configuration. The 2500 MHz boost clock is 4.2% higher than the Intel part's 2400 MHz. The base clock advantage is much larger: 1500 MHz versus 300 MHz, a 400% difference. The dedicated 16 GB LPDDR5 memory with 51.20 GB/s bandwidth contrasts with the Intel part's system shared memory, where bandwidth is system dependent. The AMD part's memory bandwidth is fixed and predictable, while the Intel part's memory performance cannot be evaluated without knowing the host platform.

The TDP comparison shows the Intel part operating at 25 W, which is 16.7% lower than the AMD part's 30 W. This means the Intel part delivers its higher compute throughput at lower power draw, a notable efficiency result given the 140% FP32 advantage. The process node difference may contribute here: Intel's 3 nm process versus AMD's 4 nm process.

Both processors are still marked as Active in production status. The AMD Ryzen Z1 GPU has a launch MSRP of 599 USD, while the Intel Arc Pro B370 has no launch MSRP recorded. The AMD part's physical dimensions are specified at 280 mm length, 111 mm height, and 21 mm width, while the Intel part's dimensions are not listed due to its IGP form factor.

Given the lack of benchmark data, the specification comparison suggests the Intel Arc Pro B370 would dominate in compute-heavy and fill-rate-limited workloads, while the AMD Ryzen Z1 GPU would offer more consistent memory performance and higher clock behavior. The actual performance relationship will require benchmark data to confirm, but the recorded specifications show a clear structural advantage for the Intel part in most measured throughput categories.
