AMD Ryzen Z1 GPU vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Ryzen Z1 GPU and the Intel Arc B370, as the head-to-head benchmark array is empty. However, the Intel Arc B370 has a single recorded 3DMark Steel Nomad DX12 score of 1184, which places it at the 5th percentile among all GPUs in the database. The AMD Ryzen Z1 GPU has no benchmark scores on record, with an average benchmark score of 0 and a 50th percentile ranking, meaning it sits at the midpoint of the database distribution despite lacking measured performance data.

For the Intel Arc B370, its nearest rivals in the database provide context for its performance level. The ATI Mobility Radeon HD 5570 records an average score of 1186, which is 0.2% higher than the Arc B370, indicating a virtual tie in raw performance. The ATI Radeon HD 5770 scores 1190, 0.5% higher, while the AMD Radeon HD 7650M achieves 1192, 0.7% higher. On the other side, the AMD FirePro M2000 scores 1168, which is 1.4% lower than the Arc B370. This cluster of results shows the Arc B370 performing within a narrow band of older discrete and mobile graphics solutions, with all deltas under 1.5% in either direction.

The absence of any benchmark data for the Ryzen Z1 GPU means the database cannot establish a comparable performance figure for that part. Its 50th percentile ranking is a positional placeholder rather than a measured outcome, as the average benchmark score of 0 confirms no tests have been submitted. Consequently, the head-to-head comparison rests entirely on architectural and specification differences, not on direct measured outcomes. The wins count stands at 0 for both parts, reflecting the lack of recorded comparative tests.

Architecture Differences

The AMD Ryzen Z1 GPU is built on the Phoenix chip using RDNA 3.0 architecture, fabricated on a 4 nm process at TSMC with 25,390 million transistors on a 178 mm² die. The transistor density works out to 142.6 million transistors per square millimeter. The Intel Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel, with transistor count and die size listed as unknown in the database.

The compute resources differ substantially. The Ryzen Z1 GPU has 256 shading units, 16 texture mapping units, and 8 ROPs, along with 4 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, and 20 ROPs, with 10 ray tracing cores. These counts indicate the Arc B370 carries five times the shading units, 2.5 times the TMUs, 2.5 times the ROPs, and 2.5 times the ray tracing cores of the Ryzen Z1 GPU. Neither part lists tensor cores in the database.

The memory architecture is a key differentiator. The Ryzen Z1 GPU has dedicated 16 GB of LPDDR5 memory with a 64-bit bus and 51.20 GB/s bandwidth, with memory clocked at 800 MHz and 6.4 Gbps effective. The Arc B370 has no dedicated memory; its memory size, type, and bus width are all listed as system shared, with bandwidth described as system dependent. This means the Arc B370 relies entirely on the host system's memory subsystem, while the Ryzen Z1 GPU has its own dedicated pool.

Clock speeds also differ. The Ryzen Z1 GPU has a base clock of 1500 MHz and a boost clock of 2500 MHz, with a memory clock of 800 MHz. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with memory clock listed as system shared. The Ryzen Z1 GPU runs at a much higher base clock, while the boost clocks are relatively close at 2500 MHz versus 2400 MHz.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. They are both listed as active production parts. The release dates differ, with the Ryzen Z1 GPU released on 2023-09-17 and the Arc B370 released on 2026-01-26.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The AMD Ryzen Z1 GPU uses a 4 nm process at TSMC, while the Intel Arc B370 uses a 3 nm process at Intel. The Ryzen Z1 GPU has 25,390 million transistors on a 178 mm² die with a density of 142.6 million per square millimeter; the Arc B370 lists all three as unknown or null.

Clock specifications diverge sharply. The Ryzen Z1 GPU has a base clock of 1500 MHz and a boost clock of 2500 MHz, with a memory clock of 800 MHz and 6.4 Gbps effective. The Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with system shared memory clock.

Memory configurations are fundamentally different. The Ryzen Z1 GPU has 16 GB of LPDDR5 on a 64-bit bus with 51.20 GB/s bandwidth. The Arc B370 has system shared memory for size, type, bus width, and bandwidth is system dependent.

Compute unit counts favor the Arc B370 heavily. The Ryzen Z1 GPU has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. Neither has tensor cores listed.

Pixel and texture rates reflect these differences. The Ryzen Z1 GPU achieves 20.00 GPixel/s and 40.00 GTexel/s, while the Arc B370 achieves 48.00 GPixel/s and 96.00 GTexel/s. The FP32 throughput is 2.560 TFLOPS for the Ryzen Z1 GPU versus 6.144 TFLOPS for the Arc B370. FP16 throughput is 5.120 TFLOPS for the Ryzen Z1 GPU versus 12.29 TFLOPS for the Arc B370, both at a 2:1 ratio.

Power and physical characteristics differ as well. The Ryzen Z1 GPU has a TDP of 30 W, while the Arc B370 has a TDP of 25 W. The Ryzen Z1 GPU has dimensions of 280 mm length, 111 mm height, and 21 mm width, while the Arc B370 has no recorded dimensions. The Arc B370 is an IGP with no slot width and uses an IGP bus interface; the Ryzen Z1 GPU has no slot width listed and no bus interface specified. Both have no power connectors.

Display outputs differ. The Ryzen Z1 GPU has no outputs, while the Arc B370 has portable device dependent outputs. The Ryzen Z1 GPU has a launch MSRP of 599 USD, while the Arc B370 has no launch MSRP on record.

The Verdict

The data shows two GPUs designed for fundamentally different roles. The AMD Ryzen Z1 GPU, released in 2023, is a dedicated mobile graphics solution with its own 16 GB of LPDDR5 memory, a 64-bit bus, and 51.20 GB/s of bandwidth. It draws 30 W and has a launch MSRP of 599 USD. Its compute resources are modest at 256 shading units, but it carries a dedicated memory pool that provides predictable bandwidth independent of the host system.

The Intel Arc B370, released in 2026, is an integrated graphics processor (IGP) on the Panther Lake chip. It has no dedicated memory, relying entirely on system shared memory with system-dependent bandwidth. Despite this, it offers substantially higher raw compute resources: 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. Its FP32 throughput of 6.144 TFLOPS is 2.4 times the Ryzen Z1 GPU's 2.560 TFLOPS. Its pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are both 2.4 times the Ryzen Z1 GPU's respective figures.

The recorded benchmark data only covers the Arc B370, which scores 1184 in 3DMark Steel Nomad DX12 and sits at the 5th percentile. Its nearest rivals, all older discrete or mobile parts, are within 1.5% of its performance. The Ryzen Z1 GPU has no measured scores, so its real-world performance cannot be quantified from the database.

For users who need a dedicated memory pool with guaranteed bandwidth, the Ryzen Z1 GPU provides that capability, though its compute throughput is lower. For users who need maximum raw shading power, ray tracing resources, and pixel throughput in an integrated form factor, the Arc B370 is the stronger part on paper. The Arc B370 also consumes less power at 25 W versus 30 W for the Ryzen Z1 GPU. The choice depends on whether dedicated memory or raw compute matters more, and the database currently only validates the Arc B370's performance through a single benchmark score.
