Architecture Differences

The AMD Ryzen Z1 GPU is built on the RDNA 3.0 architecture, using AMD's Phoenix chip. It is manufactured on a 4 nm process by TSMC, with 25,390 million transistors packed into a 178 mm² die. This transistor density works out to 142.6 million transistors per square millimeter. The Intel Arc G3 uses the Xe3-LPG architecture, based on the Panther Lake chip, and is fabricated on Intel's 3 nm process. The database does not record transistor count, die size, or density for the Intel part.

The compute resource allocation differs substantially. The AMD Ryzen Z1 GPU contains 256 shading units, 16 texture mapping units, and 8 raster output pipelines. The Intel Arc G3 has 1280 shading units, 40 TMUs, and 20 ROPs. This gives the Intel part 5 times the shading units, 2.5 times the TMUs, and 2.5 times the ROPs. For ray tracing, the AMD part has 4 RT cores, while the Intel part has 10, a 2.5 times advantage.

Clock behavior also differs. The AMD Ryzen Z1 GPU runs at a base clock of 1500 MHz and boosts to 2500 MHz. The Intel Arc G3 has a much lower base clock of 300 MHz but boosts to 2400 MHz. The memory clock is recorded as 800 MHz with 6.4 Gbps effective data rate for the AMD part, while the Intel part uses system shared memory with no dedicated memory clock listed.

The Intel Arc G3 is an integrated graphics processor (IGP) with no separate slot width, power connectors, or bus interface beyond the IGP designation. The AMD Ryzen Z1 GPU has dimensions recorded as 280 mm length, 111 mm height, and 21 mm width, while the Intel part has no dimensions recorded. Display outputs differ as well: the AMD part has no outputs, while the Intel part's outputs are listed as portable device dependent.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as active production parts. The AMD Ryzen Z1 GPU was released on September 17, 2023, while the Intel Arc G3 has a release date of May 31, 2026.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries for these two GPUs. Both have an average benchmark score of zero and a percentile rank of 50 among all GPUs in the database. The nearest rivals lists are empty for both parts. Therefore, the comparison must rely entirely on the specification-derived performance metrics.

In FP32 compute, the Intel Arc G3 delivers 6.144 TFLOPS, which is 140% higher than the AMD Ryzen Z1 GPU's 2.560 TFLOPS. This is the largest single-metric advantage in the comparison. The FP16 figures follow the same pattern, with the Intel part reaching 12.29 TFLOPS versus 5.120 TFLOPS for the AMD part, a 140% lead again.

Texture throughput shows a similar gap. The Intel Arc G3 achieves 96.00 GTexel/s, while the AMD Ryzen Z1 GPU manages 40.00 GTexel/s. This is a 56.00 GTexel/s difference, representing a 140% advantage for Intel. Pixel fill rate favors Intel as well: 48.00 GPixel/s versus 20.00 GPixel/s, a 28.00 GPixel/s gap.

The AMD Ryzen Z1 GPU does hold advantages in certain areas. Its boost clock of 2500 MHz exceeds the Intel part's 2400 MHz by 100 MHz. The base clock gap is far larger: 1500 MHz versus 300 MHz, a 1200 MHz difference in favor of AMD. The AMD part also has a dedicated 16 GB memory pool with 51.20 GB/s bandwidth, whereas the Intel part's memory performance is listed as system dependent and cannot be directly quantified.

Power efficiency, when normalized to compute output, favors the Intel Arc G3. At 25 W TDP, the Intel part delivers 6.144 TFLOPS, yielding 0.246 TFLOPS per watt. The AMD part at 30 W delivers 2.560 TFLOPS, which is 0.085 TFLOPS per watt. The Intel part achieves roughly three times the FP32 throughput per watt based on these recorded figures.

Where Each One Wins

The Intel Arc G3 wins in raw compute throughput across every measured rate. Its FP32 output of 6.144 TFLOPS is more than double the AMD part's 2.560 TFLOPS. The same ratio applies to FP16, texture fill, and pixel fill. For workloads dominated by shading, texture sampling, or rasterization, the Intel part has a clear numerical advantage. The higher shading unit count of 1280 versus 256 supports this dominance in shader-bound scenarios. The 10 RT cores versus 4 also positions the Intel part ahead for ray tracing workloads.

The AMD Ryzen Z1 GPU wins on clock frequency and dedicated memory. Its 2500 MHz boost clock is 100 MHz higher than the Intel part's 2400 MHz. The base clock advantage is far more pronounced at 1500 MHz versus 300 MHz. For applications that scale with clock speed rather than raw unit count, the AMD part may show relatively better responsiveness. The dedicated 16 GB LPDDR5 pool with 51.20 GB/s bandwidth provides predictable memory performance, whereas the Intel part depends entirely on system memory, making its effective bandwidth variable.

Power consumption favors the AMD part in absolute terms if the metric is total draw, since 30 W is higher than 25 W. However, the Intel part delivers more compute per watt. In a fixed power envelope, the Intel Arc G3 would complete more work. The AMD part's higher TDP suggests it draws more power, but its lower compute rates mean each unit of work costs more energy.

For integrated use cases, the Intel Arc G3 is designed as an IGP with portable device dependent outputs, indicating it targets mobile or compact systems. The AMD Ryzen Z1 GPU, with its 280 mm board length and no display outputs, appears intended for a different form factor, possibly a separate processing unit. The release dates also separate them: the AMD part launched in 2023, while the Intel part is scheduled for 2026, suggesting different market timing.

Use cases where the AMD Ryzen Z1 GPU would be preferable include scenarios requiring a fixed, predictable memory subsystem, or workloads sensitive to clock speed. The higher boost clock and dedicated memory could benefit latency-sensitive tasks. The Intel Arc G3 suits throughput-oriented workloads, shader-heavy rendering, and ray tracing, where its larger unit counts and higher fill rates provide measurable advantages. The recorded data, absent direct benchmarks, points to the Intel part as the stronger compute performer, while the AMD part offers a more controlled memory environment and higher clock ceilings.
