Architecture Differences

The two Intel GPUs represent fundamentally different design targets within the same manufacturer's portfolio. The Intel Arc Graphics 4 Xe Mobile is built on Panther Lake using the Xe3-LPG architecture, fabricated on Intel's 3 nm process. The Intel Data Center GPU Max Subsystem uses Ponte Vecchio with Generation 12.5 architecture on a 10 nm process. This process difference alone explains much of the divergence in clock speeds and power characteristics.

The mobile part operates with a 300 MHz base clock and a 2300 MHz boost clock, indicating a design optimized for efficiency within a 25 W TDP envelope. The data center part runs at 900 MHz base and 1600 MHz boost, with a 2400 W TDP. The transistor counts tell a dramatic story: the data center GPU integrates 100,000 million transistors on a 1280 mm² die, achieving a density of 78.1M transistors per mm². The mobile GPU's transistor count and die size are not recorded in the database.

Shader resources differ by a factor of 32. The mobile GPU contains 512 shading units, 32 texture mapping units, 16 ROPs, and 4 ray tracing cores. The data center GPU contains 16,384 shading units, 1024 TMUs, 0 ROPs, and 128 ray tracing cores. The absence of ROPs on the data center part is notable; its pixel rate is recorded as 0 MPixel/s, confirming that the device is not designed for rasterized display output. Its texture rate of 1,638.4 GTexel/s dwarfs the mobile part's 73.60 GTexel/s.

Memory architecture is entirely different. The mobile GPU shares system memory with no dedicated bus width and bandwidth that depends on the host platform. The data center GPU has 128 GB of HBM2e memory on a 8192 bit bus with 3.21 TB/s bandwidth. Memory clocks differ as well: the mobile part uses System Shared memory, while the data center part runs at 1565 MHz with 3.1 Gbps effective data rate.

API support shows another split. The mobile GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The data center GPU supports DirectX 12 (12_1) and OpenGL 4.6, with no Vulkan support recorded. The data center part also has no display outputs, while the mobile part's outputs are described as Portable Device Dependent.

The power delivery infrastructure reflects the scale difference. The mobile GPU is an IGP with no power connectors and a 25 W TDP. The data center GPU is a dual-slot PCIe 5.0 x16 card, 267 mm long, requiring one 16-pin connector and a suggested power supply of 2800 W.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two products, and neither GPU has an average benchmark score or a list of nearest rivals. However, the recorded specifications permit direct quantitative comparisons across compute, memory, and rendering metrics.

The FP32 throughput difference is the most decisive specification gap. The Intel Data Center GPU Max Subsystem produces 52.43 TFLOPS, which is 22.3 times the 2.355 TFLOPS of the Intel Arc Graphics 4 Xe Mobile. In FP16, the gap narrows slightly on a ratio basis but remains massive: the data center part delivers 52.43 TFLOPS (1:1), while the mobile part delivers 4.710 TFLOPS (2:1). The mobile part's 2:1 ratio indicates it uses hardware acceleration for FP16, but the absolute difference of 47.72 TFLOPS leaves no ambiguity about which device handles compute workloads faster.

Texture throughput follows a similar pattern. The data center GPU achieves 1,638.4 GTexel/s against the mobile GPU's 73.60 GTexel/s, a 22.3 times advantage that mirrors the FP32 ratio. Pixel rate inverts the comparison: the data center GPU records 0 MPixel/s, while the mobile GPU produces 36.80 GPixel/s. This confirms that the data center part lacks the fixed-function rasterization pipeline needed for display output, whereas the mobile part retains full graphics capability.

Memory bandwidth is another area of enormous separation. The data center GPU's 3.21 TB/s is achieved through HBM2e across an 8192 bit interface. The mobile GPU's bandwidth is System Dependent, meaning its performance scales with whatever memory controller the host processor provides. The 128 GB capacity of the data center part is fixed and dedicated; the mobile part has no dedicated capacity at all.

Clock behavior favors the mobile part on boost frequency. The 2300 MHz boost of the Intel Arc Graphics 4 Xe Mobile is 43.75% higher than the 1600 MHz boost of the data center part. The base clock comparison reverses this: the data center part runs at 900 MHz, which is three times the mobile part's 300 MHz base. The mobile part's wider clock range suggests aggressive power management, while the data center part maintains a narrower operating range suitable for sustained throughput.

Both GPUs share a 50th percentile ranking against all GPUs in the database, despite their radically different specifications. This percentile field does not distinguish between the two products, and with no average benchmark scores recorded, the ranking cannot be further resolved from the available data.

The Verdict

The recorded data describes two Intel GPUs with opposite design philosophies. The Intel Arc Graphics 4 Xe Mobile is an integrated solution for portable devices, built on a 3 nm process with a 25 W TDP, system-shared memory, and a full set of graphics APIs including DirectX 12 Ultimate and Vulkan 1.4. Its 2300 MHz boost clock and 36.80 GPixel/s pixel rate indicate a part intended for rendering and display.

The Intel Data Center GPU Max Subsystem is a 2400 W accelerator with 128 GB of HBM2e, 16,384 shading units, and 52.43 TFLOPS of FP32 throughput. It has no ROPs, no display outputs, and no Vulkan support. Its DirectX 12 (12_1) support is one generation behind the mobile part's DirectX 12 Ultimate (12_2). This is a compute device, not a graphics device.

The choice between them depends entirely on workload class. For portable graphics, rasterization, and display output, the Intel Arc Graphics 4 Xe Mobile is the only viable option; the data center part cannot output video and has a 2400 W power requirement. For FP32-heavy compute, memory-bandwidth-bound workloads, or large model inference, the Intel Data Center GPU Max Subsystem's 22.3 times FP32 advantage and 3.21 TB/s of memory bandwidth make it the dominant performer. The mobile part's System Dependent bandwidth and 2.355 TFLOPS cannot approach those figures.

The data center GPU also carries a successor designation in the database: H3C Graphics. The mobile part has no recorded predecessor or successor, indicating it is a current generation product. Both parts are listed as Active in production status, and both have a release date recorded in the database, with the data center part released earlier.
