Intel Arc Pro B70 vs Intel Data Center GPU Max Subsystem Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the Intel Arc Pro B70 versus the Intel Data Center GPU Max Subsystem. Both products currently hold an identical percentile ranking of 50 against all GPUs, and neither has an average benchmark score recorded. This absence of comparative data means the two cards cannot be ranked against one another through measured performance metrics at this time.

What the available data does show is a dramatic split in raw compute capabilities. The Data Center GPU Max Subsystem delivers 52.43 TFLOPS of FP32 throughput, which is 2.29 times the 22.94 TFLOPS offered by the Arc Pro B70. In FP16 work, the gap narrows in one sense but widens in another: the Data Center GPU Max Subsystem maintains 52.43 TFLOPS at a 1:1 ratio, while the Arc Pro B70 reaches 45.88 TFLOPS using a 2:1 ratio. So in pure FP16 throughput the Data Center part still leads by roughly 14 percent, but the Arc Pro B70's 2:1 rate suggests a different design priority.

Texture processing tells a similar story. The Data Center GPU Max Subsystem reaches 1,638.4 GTexel/s, which is 2.29 times the Arc Pro B70's 716.8 GTexel/s. Pixel rate, however, is a complete mismatch: the Data Center GPU Max Subsystem reports 0 MPixel/s because it has zero raster operation units (ROPs), while the Arc Pro B70 produces 358.4 GPixel/s. The Data Center part is not designed for traditional rasterized graphics output, which explains this unusual specification.

Memory bandwidth is where the Data Center GPU Max Subsystem establishes its largest advantage. Its HBM2e stack delivers 3.21 TB/s across a 8192-bit bus, which is 5.28 times the Arc Pro B70's 608.0 GB/s from a 256-bit GDDR6 interface. That bandwidth disparity fundamentally changes what workloads each card can handle.

Architecture Differences

The two GPUs come from entirely different Intel lineages. The Arc Pro B70 uses the BMG-G31 chip based on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. The Data Center GPU Max Subsystem uses the Ponte Vecchio chip with Generation 12.5 architecture. These are not iterative improvements of the same design; they are parallel product families aimed at different workloads.

Manufacturing processes diverge sharply. The Arc Pro B70 is built on a 5 nm node at TSMC, while the Data Center GPU Max Subsystem uses a 10 nm node at Intel's own foundry. The Data Center part packs 100,000 million transistors onto a 1280 mm² die, achieving a transistor density of 78.1 million per mm². The Arc Pro B70's die measures 368 mm², but its transistor count is listed as unknown in the database, so a direct density comparison is not possible. The die size difference alone, 1280 mm² versus 368 mm², indicates the Data Center GPU is a massive silicon assembly relative to the Arc Pro B70.

Clock speeds reflect the same split. The Arc Pro B70 runs at a 2280 MHz base and 2800 MHz boost, while the Data Center GPU Max Subsystem operates at 900 MHz base and 1600 MHz boost. The Arc Pro B70's higher clocks are typical of a graphics-focused card, whereas the Data Center part favors a wider, slower design. Memory clocks follow suit: 2375 MHz (19 Gbps effective) on the Arc Pro B70 versus 1565 MHz (3.1 Gbps effective) on the Data Center GPU Max Subsystem.

Shader resources differ in scale. The Data Center GPU Max Subsystem has 16,384 shading units, 1,024 TMUs, and 128 ray tracing cores. The Arc Pro B70 has 4,096 shading units, 256 TMUs, and 32 ray tracing cores. That is a 4:1 ratio in each category. In terms of the architectural response, the Data Center part quadruples the Arc Pro B70's execution resources in both shading and texture work.

The API support also differs. The Arc Pro B70 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 Vulkan support is not recorded. Feature-level differences in DirectX indicate the Arc Pro B70 targets newer graphics workloads, while the Data Center part omits certain consumer-facing capabilities.

Where Each One Wins

The Arc Pro B70 wins in every category related to traditional graphics rendering. It has 128 ROPs versus zero on the Data Center part, enabling a pixel rate of 358.4 GPixel/s. It also carries display outputs, supporting up to one HDMI 2.1a and three DisplayPort 2.1 connections. The DirectX 12 Ultimate feature set and Vulkan 1.4 support position it for modern consumer and professional graphics workloads. Its higher clock speeds, 2800 MHz boost versus 1600 MHz, also favor latency-sensitive rendering tasks.

The Data Center GPU Max Subsystem wins decisively in compute density and memory capacity. Its 52.43 TFLOPS FP32 performance and 3.21 TB/s bandwidth serve workloads that move massive datasets. The 128 GB HBM2e pool is four times larger than the Arc Pro B70's 32 GB, and the 8192-bit bus width provides the bandwidth to feed 16,384 shading units. The 1:1 FP16 ratio means it does not rely on a 2:1 conversion rate, which matters for workloads that need full precision in half-precision arithmetic.

The power envelope separates their deployment contexts. The Arc Pro B70 draws 230 W and fits within a 550 W PSU recommendation, while the Data Center GPU Max Subsystem requires 2400 W and a 2800 W PSU. Physical size is similar at 267 mm length, but the power and cooling demands are not in the same class.

The Verdict

The data points to two distinct products serving separate purposes. The Intel Arc Pro B70, released 2026-03-25, is a graphics-oriented card with display outputs, rasterization hardware, and a 230 W power profile. Its 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 performance, combined with 32 GB GDDR6 memory and modern API support, suit workstation graphics and professional visualization tasks.

The Intel Data Center GPU Max Subsystem, released 2023-01-09 and still marked as Active production, is a compute-focused accelerator. With 128 GB HBM2e, 52.43 TFLOPS FP32, 3.21 TB/s bandwidth, and no display outputs, it is designed for data center workloads that prioritize memory capacity and throughput over rendering. Its 2400 W TDP and 2800 W PSU requirement indicate a rack-mounted deployment rather than a desktop workstation.

The Arc Pro B70 carries a launch MSRP of 949 USD, which the database records once. The Data Center GPU Max Subsystem has no launch MSRP listed. Neither card has a benchmark score or head-to-head result in the database, so any direct performance comparison must rely on specification analysis rather than measured outcomes.

Users who need a GPU with display connectivity, rasterization capability, and manageable power consumption should select the Arc Pro B70. Users who need maximum memory bandwidth, large memory capacity, and raw FP32 compute should select the Data Center GPU Max Subsystem, provided they can supply 2400 W of power. The architecture split, 5 nm TSMC versus 10 nm Intel, and the 4:1 ratio in shading units, point to fundamentally different design goals. The Arc Pro B70 is a graphics card with compute ability; the Data Center GPU Max Subsystem is a compute engine without graphics output.
