Where Each One Wins

The data indicates a clear functional split. The Arc Pro B370 is designed for integrated, low-power client devices. Its 25 W TDP, lack of power connectors, and IGP bus interface make it suitable for portable systems where power efficiency is paramount. The Data Center GPU Max Subsystem, with its 2400 W TDP, dual-slot footprint, and 1x 16-pin power connector, targets high-performance compute environments.

In terms of raw compute throughput, the Data Center GPU Max Subsystem dominates. It delivers 52.43 TFLOPS of FP32 performance versus 6.144 TFLOPS for the Arc Pro B370. The texture rate also shows a massive gap: 1,638.4 GTexel/s versus 96.00 GTexel/s. The Data Center GPU Max Subsystem also has substantially more RT cores: 128 versus 10.

The Arc Pro B370 wins in display capabilities. It has display outputs that are portable device dependent, while the Data Center GPU Max Subsystem has no outputs. The Arc Pro B370 also supports newer graphics APIs, including DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Data Center GPU Max Subsystem is limited to DirectX 12 (12_1) and has no Vulkan support.

The Data Center GPU Max Subsystem has a higher base clock at 900 MHz versus 300 MHz, but the Arc Pro B370 has a higher boost clock at 2400 MHz versus 1600 MHz. The Arc Pro B370 also has a pixel rate of 48.00 GPixel/s, while the Data Center GPU Max Subsystem has a pixel rate of 0 MPixel/s, which indicates it is not designed for rasterized graphics output.

Architecture Differences

The two GPUs represent divergent design philosophies within Intel's portfolio. The Arc Pro B370 uses the Xe3-LPG architecture on a 3 nm process node. This architecture is integrated onto the Panther Lake chip, and the GPU functions as an IGP with no separate bus interface. The Xe3-LPG architecture supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, indicating a focus on modern graphics features.

The Data Center GPU Max Subsystem uses the Generation 12.5 architecture on a 10 nm process node. This is a discrete, dual-slot card with a PCIe 5.0 x16 interface. The chip is Ponte Vecchio, which contains 100,000 million transistors on a 1280 mm² die, yielding a transistor density of 78.1M / mm². The architecture supports DirectX 12 (12_1) but no Vulkan.

The memory architecture differs fundamentally. The Arc Pro B370 uses system shared memory, meaning there is no dedicated VRAM. The Data Center GPU Max Subsystem uses 128 GB of HBM2e across an 8192-bit bus. The memory clock for the Data Center GPU Max Subsystem is 1565 MHz with 3.1 Gbps effective speed.

The compute resources are heavily skewed toward the Data Center GPU Max Subsystem. It has 16,384 shading units, 1,024 TMUs, and 128 RT cores. The Arc Pro B370 has 1,280 shading units, 40 TMUs, and 10 RT cores. Neither GPU lists tensor cores in the data.

The FP16 performance also reveals different design priorities. The Arc Pro B370 delivers 12.29 TFLOPS FP16 at a 2:1 ratio relative to FP32. The Data Center GPU Max Subsystem delivers 52.43 TFLOPS FP16 at a 1:1 ratio, indicating that it maintains full throughput for both precision formats.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores between these two GPUs, and neither has an average benchmark score above zero. The wins tally is zero for both. The comparison must therefore rely on the recorded architectural and specification data.

The most significant performance gap appears in FP32 compute. The Data Center GPU Max Subsystem delivers 52.43 TFLOPS, which is 8.5 times the 6.144 TFLOPS of the Arc Pro B370. This indicates a clear advantage for the Data Center GPU Max Subsystem in general-purpose compute workloads.

Texture throughput shows an even larger disparity. The Data Center GPU Max Subsystem achieves 1,638.4 GTexel/s, which is 17 times the 96.00 GTexel/s of the Arc Pro B370. This suggests that the Data Center GPU Max Subsystem is substantially better suited for workloads that rely on texture sampling.

The FP16 comparison shows the Data Center GPU Max Subsystem matches its FP32 output at 52.43 TFLOPS. The Arc Pro B370 achieves 12.29 TFLOPS FP16, which is double its FP32 rate. The Data Center GPU Max Subsystem still leads by a factor of 4.3 in FP16 throughput.

The RT core count differs by a factor of 12.8, with the Data Center GPU Max Subsystem having 128 RT cores versus 10 for the Arc Pro B370. This indicates a substantial advantage for ray tracing workloads on the Data Center GPU Max Subsystem.

The pixel rate is the only metric where the Arc Pro B370 records a non-zero value. It delivers 48.00 GPixel/s, while the Data Center GPU Max Subsystem records 0 MPixel/s. This confirms that the Arc Pro B370 is capable of rasterized output, whereas the Data Center GPU Max Subsystem is not designed for that task.

The memory bandwidth difference is also substantial. The Data Center GPU Max Subsystem offers 3.21 TB/s, while the Arc Pro B370 bandwidth is system dependent and therefore variable. The 128 GB HBM2e capacity on the Data Center GPU Max Subsystem provides a dedicated memory pool that the Arc Pro B370 cannot match with its system shared configuration.

Both GPUs are listed as active in production, and both occupy the 50th percentile among all GPUs in the database. The release dates show the Data Center GPU Max Subsystem shipped approximately three years earlier than the Arc Pro B370.
