Architecture Differences

The Intel Arc Pro B390 is built on the Xe3-LPG architecture, which is the graphics component of the Panther Lake chip. It uses a 3 nm process node manufactured by Intel. The chip integrates the GPU directly into the processor package, as indicated by its IGP bus interface and slot width. This integration means the GPU shares system memory rather than having dedicated VRAM. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Intel Data Center GPU Max Subsystem is built on the Generation 12.5 architecture, specifically designed for data center workloads. It uses a much larger Ponte Vecchio chip fabricated on a 10 nm process. The die size is 1280 mm², and the chip contains 100,000 million transistors, resulting in a transistor density of 78.1M per mm². This is a discrete accelerator card with a dual-slot form factor, using a PCIe 5.0 x16 bus interface. It has no display outputs, as it is designed for compute tasks rather than graphics rendering.

The memory architectures differ fundamentally. The Arc Pro B390 relies on system shared memory with system-dependent bandwidth, while the Data Center GPU Max Subsystem uses 128 GB of HBM2e memory on an 8192-bit bus, delivering 3.21 TB/s of bandwidth. The memory clock for the data center part is 1565 MHz, with 3.1 Gbps effective data rate.

The compute configurations also diverge significantly. The Arc Pro B390 has 1536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The Data Center GPU Max Subsystem has 16384 shading units, 1024 TMUs, 128 ray tracing cores, and zero ROPs. The absence of ROPs in the data center part reflects its compute-focused design, as it does not need to rasterize graphics to a display.

The Verdict

The recorded data shows two entirely different product categories. The Intel Arc Pro B390 is an integrated GPU meant for portable devices, as indicated by its display outputs being portable device dependent. Its low TDP of 80 W and lack of power connectors confirm it is designed for power-constrained systems. It offers modern graphics API support including DirectX 12 Ultimate and Vulkan 1.4, making it suitable for general graphics workloads in mobile or embedded contexts.

The Intel Data Center GPU Max Subsystem is a high-performance compute accelerator. Its 128 GB of HBM2e memory and 3.21 TB/s bandwidth, combined with 52.43 TFLOPS of FP32 performance, position it for large-scale data center compute tasks. The 2400 W TDP and suggested PSU of 2800 W indicate it requires dedicated server infrastructure.

Users needing a graphics solution for a compact, low-power device should choose the Arc Pro B390. Users requiring massive parallel compute throughput and large memory capacity for server deployments should choose the Data Center GPU Max Subsystem. The two products do not compete in the same performance or power envelope.

Head-to-Head Benchmarks

The benchmark data shows no recorded head-to-head comparisons between these two products, and both have an average benchmark score of zero. However, the theoretical specifications provide clear performance indicators.

The Intel Data Center GPU Max Subsystem dominates in raw compute throughput. Its FP32 performance of 52.43 TFLOPS is more than six times the 7.680 TFLOPS of the Arc Pro B390. The FP16 performance gap is narrower but still substantial: the data center part delivers 52.43 TFLOPS at a 1:1 ratio, while the Arc Pro B390 achieves 15.36 TFLOPS at a 2:1 ratio. This means the data center GPU maintains full FP16 throughput without relying on packed math, a significant advantage for workloads using reduced precision.

The texture rate difference is even more pronounced. The Data Center GPU Max Subsystem achieves 1,638.4 GTexel/s, which is over thirteen times the 120.0 GTexel/s of the Arc Pro B390. This indicates a much higher capacity for texture-heavy compute operations.

The memory subsystem is where the data center part has the largest relative advantage. With 3.21 TB/s of bandwidth, it exceeds the system-dependent bandwidth of the Arc Pro B390 by an order of magnitude. The 128 GB capacity versus system shared memory also eliminates any capacity constraints for large datasets.

The Arc Pro B390 counters with a significantly higher boost clock of 2500 MHz versus 1600 MHz. It also has a lower base clock of 300 MHz versus 900 MHz, showing a wider clock range. The pixel rate of 60.00 GPixel/s for the Arc Pro B390 contrasts with the 0 MPixel/s of the data center part, confirming the former's capability as a graphics output device.

The transistor count difference is substantial: the Ponte Vecchio chip contains 100,000 million transistors on a 1280 mm² die, while the Panther Lake chip's transistor count is unknown. The data center GPU also has a higher transistor density at 78.1M per mm².

The shading unit count favors the data center part by a factor of over ten: 16384 versus 1536. Similarly, the TMU count is 1024 versus 48, and ray tracing cores are 128 versus 12. These disparities indicate the data center GPU is designed for massively parallel workloads, while the Arc Pro B390 targets conventional graphics rendering in power-limited environments.

The release dates differ by roughly three years, with the Data Center GPU Max Subsystem launching on 2023-01-09 and the Arc Pro B390 on 2026-01-26. Both products are currently listed as Active in production status.
