Architecture Differences

The two GPUs represent fundamentally different design philosophies within Intel's product stack. The Arc Pro B65 uses the Xe2-HPG architecture on a 5 nm TSMC process, featuring 19,600 million transistors on a 272 mm² die. The Data Center GPU Max Subsystem uses Generation 12.5 architecture on Intel's 10 nm process, with 100,000 million transistors on a 1280 mm² die. The transistor density figures are similar (72.1M / mm² for the Arc Pro B65 versus 78.1M / mm² for the Data Center GPU Max Subsystem), but the sheer scale of the data center part is dramatically larger.

The compute configuration diverges significantly. The Arc Pro B65 has 2560 shading units, 160 texture mapping units, 80 ROPs, and 20 ray tracing cores. The Data Center GPU Max Subsystem has 16,384 shading units, 1024 texture mapping units, 0 ROPs, and 128 ray tracing cores. The absence of ROPs in the data center part underscores its compute-focused design with no rasterization pipeline.

Memory architecture represents another major split. The Arc Pro B65 uses 32 GB of GDDR6 on a 256-bit bus. The Data Center GPU Max Subsystem uses 128 GB of HBM2e on an 8192-bit bus, yielding a bandwidth figure of 3.21 TB/s versus 608.0 GB/s. The memory clock differences are notable as well: the Arc Pro B65 runs at 2375 MHz (19 Gbps effective) while the Data Center GPU Max Subsystem runs at 1565 MHz (3.1 Gbps effective), though the vastly wider bus more than compensates.

API support shows a generational split. The Arc Pro B65 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Data Center GPU Max Subsystem supports DirectX 12 (12_1) and OpenGL 4.6, but has no Vulkan support listed. This indicates the Arc Pro B65 is positioned for modern graphics workloads while the data center part prioritizes compute.

The physical and power characteristics differ sharply. The Arc Pro B65 is a dual-slot card with a 200 W TDP, a 550 W suggested PSU, and a single 8-pin connector. The Data Center GPU Max Subsystem is also dual-slot but consumes 2400 W, requires a 2800 W suggested PSU, uses a single 16-pin connector, and measures 267 mm (10.5 inches) in length. Both use PCIe 5.0 x16 interfaces.

The production status for both is Active. The Arc Pro B65 has a release date of 2026-03-31, while the Data Center GPU Max Subsystem was released on 2023-01-09. The data center part lists a successor in H3C Graphics.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries between these two GPUs, and both have an average benchmark score of 0 with a 50th percentile ranking against all GPUs. However, the specification data provides clear performance differentiators.

The most significant advantage for the Data Center GPU Max Subsystem is in FP32 compute throughput. It delivers 52.43 TFLOPS versus 12.29 TFLOPS for the Arc Pro B65, a 4.3x advantage. In FP16 operations, the data center part achieves 52.43 TFLOPS with a 1:1 ratio, while the Arc Pro B65 achieves 24.58 TFLOPS with a 2:1 ratio. This means the Data Center GPU Max Subsystem is 2.1x faster in FP16 as well.

Texture processing shows a similar pattern. The Data Center GPU Max Subsystem achieves a texture rate of 1,638.4 GTexel/s compared to 384.0 GTexel/s for the Arc Pro B65, a 4.3x advantage. The shading unit count of 16,384 versus 2,560 reinforces this compute-heavy design.

Memory bandwidth heavily favors the Data Center GPU Max Subsystem at 3.21 TB/s versus 608.0 GB/s, a 5.3x difference. The memory capacity advantage is 4x (128 GB versus 32 GB). These figures indicate the data center part is designed for memory-bound workloads such as large model inference or training.

The Arc Pro B65 does hold advantages in certain areas. Its pixel rate of 192.0 GPixel/s versus 0 MPixel/s for the Data Center GPU Max Subsystem confirms that the Arc Pro B65 has a full rasterization pipeline while the data center part has none. The clock speeds are also higher: 2400 MHz for both base and boost on the Arc Pro B65 versus 900 MHz base and 1600 MHz boost on the Data Center GPU Max Subsystem.

The Arc Pro B65 also supports a newer DirectX feature level (12 Ultimate 12_2 versus 12_1) and includes Vulkan 1.4 support, which the data center part lacks. Display outputs exist only on the Arc Pro B65 with 4x DisplayPort 2.1.

The transistor counts tell a story of scale: 100,000 million for the data center part versus 19,600 million for the Arc Pro B65. The die size difference is equally dramatic at 1280 mm² versus 272 mm².

Power efficiency comparisons can be derived from the data. The Arc Pro B65 delivers 12.29 TFLOPS at 200 W, which is 61.45 GFLOPS per watt. The Data Center GPU Max Subsystem delivers 52.43 TFLOPS at 2400 W, which is 21.85 GFLOPS per watt. The Arc Pro B65 is approximately 2.8x more power-efficient in FP32 throughput per watt.

The Verdict

The data indicates two distinct usage profiles. The Intel Arc Pro B65 is positioned for professional graphics work with its display outputs, modern API support, and a complete rasterization pipeline. Its 32 GB of GDDR6 memory and 608.0 GB/s bandwidth support demanding visualization tasks, while the 200 W TDP allows deployment in conventional workstation configurations.

The Intel Data Center GPU Max Subsystem is a compute accelerator with no display outputs and no ROPs. Its 128 GB of HBM2e memory with 3.21 TB/s bandwidth, combined with 52.43 TFLOPS of FP32 throughput, positions it for large-scale compute workloads. The 2400 W TDP and 2800 W suggested PSU indicate a server-class deployment scenario.

The Arc Pro B65 offers 4x the FP32 throughput per watt compared to the Data Center GPU Max Subsystem. It also provides a newer DirectX feature level, Vulkan support, and display connectivity. For graphics-intensive professional applications, the Arc Pro B65 is the only viable choice between the two given the data center part's lack of display outputs and rasterization hardware.

The Data Center GPU Max Subsystem offers 4.3x the FP32 throughput, 4x the memory capacity, and 5.3x the memory bandwidth. Its 16,384 shading units and 128 ray tracing cores provide substantial compute resources. The 1:1 FP16 ratio and 52.43 TFLOPS in both precisions indicate a design optimized for workloads that require consistent precision across formats.

The release timeline shows the Arc Pro B65 arriving in 2026 while the Data Center GPU Max Subsystem has been available since 2023, with a successor already listed. The data center part remains in Active production status despite its age.

Users requiring a professional graphics card with modern API support and display outputs should select the Arc Pro B65. Users requiring maximum compute throughput, memory capacity, and bandwidth for data center workloads should select the Data Center GPU Max Subsystem.
