Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs, but the specification sheets provide a detailed comparison across several compute metrics. The FP32 throughput gap is substantial. The Data Center GPU Max 1550 achieves 52.43 TFLOPS, which is 6.83 times the 7.680 TFLOPS of the Arc G3 Extreme. This advantage stems from the 16384 shading units versus 1536, a 10.67 times difference in raw shader count. The clock speeds partially compensate: the Arc G3 Extreme boosts to 2500 MHz, while the Data Center part boosts to 1600 MHz, giving the integrated part a 1.56 times clock advantage. Despite this, the sheer shader count difference dominates the compute comparison.

FP16 performance follows a similar pattern but with a different ratio structure. The Data Center GPU Max 1550 lists FP16 at 52.43 TFLOPS with a 1:1 ratio to FP32, meaning it treats both formats equally. The Arc G3 Extreme lists FP16 at 15.36 TFLOPS with a 2:1 ratio, indicating it processes half-precision at twice the rate of full precision. The absolute FP16 gap is 3.41 times in favor of the Data Center part.

Texture throughput shows one of the largest relative differences. The Data Center GPU Max 1550 reaches 1,638.4 GTexel/s from 1024 TMUs, while the Arc G3 Extreme reaches 120.0 GTexel/s from 48 TMUs. This is a 13.65 times advantage for the Data Center part. The TMU count ratio is 21.33 times, but the clock speed difference narrows the final throughput gap.

Pixel throughput inverts the trend. The Arc G3 Extreme achieves 60.00 GPixel/s from 24 ROPs, while the Data Center GPU Max 1550 lists 0 MPixel/s from 0 ROPs. The Data Center part has no traditional raster output pipeline, confirming its role as a compute accelerator rather than a graphics renderer. The Arc G3 Extreme, despite being an integrated part, retains full rasterization capability.

Ray tracing resources also favor the Data Center GPU Max 1550. It carries 128 RT cores compared to 12 on the Arc G3 Extreme, an 10.67 times difference that matches the shading unit ratio. However, the Data Center part lacks display outputs and Vulkan support, which limits its usefulness for graphics-oriented ray tracing workloads.

Memory bandwidth presents the most extreme specification gap. The Data Center GPU Max 1550 delivers 3.28 TB/s through 128 GB of HBM2e on an 8192-bit bus. The Arc G3 Extreme relies entirely on system shared memory, so its bandwidth is system dependent. The bus width difference is effectively infinite in absolute terms, since the Arc G3 Extreme has no dedicated memory bus. The Data Center part's 3.2 Gbps effective memory speed at 1600 MHz, combined with the 8192-bit bus, produces bandwidth that no integrated solution can approach.

Process technology and physical design further separate these parts. The Arc G3 Extreme uses a 3 nm node, while the Data Center GPU Max 1550 uses 10 nm. The Data Center die spans 1280 mm² with 100,000 million transistors, achieving a density of 78.1 million transistors per square millimeter. The Arc G3 Extreme's transistor count and die size are unknown, but the 3 nm process likely enables a far smaller die. Power consumption scales accordingly: 80 W for the Arc G3 Extreme versus 600 W for the Data Center GPU Max 1550, a 7.5 times difference. The suggested power supply for the Data Center part is 1000 W, while the Arc G3 Extreme requires no external power connectors.

The release timeline places the Data Center GPU Max 1550 first, launching in January 2023, followed by the Arc G3 Extreme in May 2026. The Data Center part has a recorded successor, H3C Graphics, while the Arc G3 Extreme lists none. Both GPUs sit at the 50th percentile versus all GPUs in the database, though this percentile reflects the absence of benchmark data rather than comparable performance levels. The Arc G3 Extreme's integrated nature and the Data Center GPU Max 1550's compute focus make direct performance comparisons less meaningful than architectural analysis. The data confirms two distinct products optimized for entirely different deployment scenarios.
