Intel Arc Graphics 2 Xe Mobile vs NVIDIA Rubin GPU Comparison

Intel Arc Graphics 2 Xe Mobile and NVIDIA Rubin GPU occupy opposite ends of the hardware spectrum. The database records show one as an integrated processor graphics solution for portable devices, the other as a server-class accelerator module. No direct head-to-head benchmark entries exist for this pairing, so the comparison relies entirely on the recorded architectural and specification data.

Head-to-Head Benchmarks

The database contains no shared benchmark scores between these two parts. Their average benchmark scores are both recorded as zero, and their percentile ranks against all GPUs are identical at 50. This reflects the absence of comparable testing rather than equivalent performance. The Intel Arc Graphics 2 Xe Mobile has no entries in its benchmark array, and the NVIDIA Rubin GPU likewise has no benchmark results recorded.

Performance indicators must be derived from the theoretical throughput figures. The NVIDIA Rubin GPU delivers 130.0 TFLOPS of FP32 compute, while the Intel Arc Graphics 2 Xe Mobile delivers 1,280.0 GFLOPS, which converts to 1.28 TFLOPS. The Rubin part therefore provides roughly 101 times the FP32 throughput of the Intel part, based strictly on these recorded figures. In FP16, the NVIDIA part reaches 260.0 TFLOPS versus the Intel part's 2.560 TFLOPS, a ratio near 101 as well, since both use the same 2:1 FP16 to FP32 ratio.

Texture processing shows a similar gap. The NVIDIA Rubin GPU achieves 2,031.2 GTexel/s, while the Intel Arc Graphics 2 Xe Mobile achieves 40.00 GTexel/s. That places the server part roughly 50 times ahead. Pixel throughput differs less dramatically but still heavily favors NVIDIA: 54.41 GPixel/s versus 20.00 GPixel/s, a factor of about 2.7. The pixel rate gap is smaller because the Rubin GPU has only 24 ROPs, a very low count for its class, while the Intel part has 8 ROPs.

Memory bandwidth is another decisive split. The NVIDIA Rubin GPU records 22.1 TB/s across a 16384-bit bus using HBM4 memory. The Intel Arc Graphics 2 Xe Mobile uses system-shared memory with bandwidth listed as system dependent, so no direct number can be compared. The Rubin's dedicated 288 GB HBM4 frame buffer stands against the Intel part's fully shared memory configuration.

Architecture Differences

The Intel Arc Graphics 2 Xe Mobile uses the Xe3-LPG architecture on a chip called Wildcat Lake, fabricated by Intel on a 3 nm process. It belongs to the Arc Graphics-M (Wildcat Lake) generation. Its transistor count and die size are both recorded as unknown. The NVIDIA Rubin GPU uses the Rubin architecture on the GR100 chip, fabricated by TSMC also on a 3 nm process, and belongs to the Server Rubin (Rxx) generation. The Rubin chip contains 336,000 million transistors on a 1456 mm² die, yielding a transistor density of 230.8M per mm². The Intel part's density cannot be calculated from the recorded data.

The compute configurations diverge sharply. The Intel part has 256 shading units, 16 TMUs, 8 ROPs, and 2 ray tracing cores. It has no tensor cores recorded. The NVIDIA part has 28,720 shading units, 896 TMUs, 24 ROPs, and 896 tensor cores. Its ray tracing core count is not recorded. The shading unit difference alone is a factor of over 112. The tensor core presence in the Rubin GPU indicates a hardware path for AI workloads, while the Intel part shows no tensor core support in the database.

Clock behavior differs in both base and boost values. The Intel Arc Graphics 2 Xe Mobile runs at a 300 MHz base and 2500 MHz boost. The NVIDIA Rubin GPU runs at a 700 MHz base and 2267 MHz boost. The Intel part has a higher boost clock, but the Rubin part starts from a much higher base. Memory clocks are recorded for the NVIDIA part as 2695 MHz with 10.8 Gbps effective data rate; the Intel part's memory clock field simply says system shared.

Power and physical configuration are not remotely comparable. The Intel part is an integrated graphics processor (IGP) with a 25 W TDP, no power connectors, and a slot width of IGP. The NVIDIA part is an SXM module with a 2300 W TDP and a suggested PSU of 2700 W. The Intel part draws display output from the portable device it is built into, while the NVIDIA part lists no display outputs at all. The bus interface for Intel is IGP, while NVIDIA uses PCIe 6.0 x16.

API support also separates the two. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part records N/A for DirectX, OpenGL, and Vulkan, indicating it is not intended for conventional graphics API workloads in the measured configuration.

Release timing is close. The NVIDIA Rubin GPU has a release date of 2025-12-31, and the Intel Arc Graphics 2 Xe Mobile follows on 2026-04-15. Both are marked as active production parts. The Intel part's predecessor is HD Graphics-M, while the NVIDIA part's predecessor is Server Blackwell. Neither has a recorded successor.

Where Each One Wins

The NVIDIA Rubin GPU wins every directly comparable computational metric. FP32 throughput, FP16 throughput, texture rate, and pixel rate all favor the server part by wide margins. Memory capacity and bandwidth favor it as well, with 288 GB of HBM4 and 22.1 TB/s versus a system-shared configuration. The tensor core count gives it a clear advantage in any recorded AI or matrix workload metric. The PCIe 6.0 x16 interface also allows it to communicate with a host system at high bandwidth, while the Intel part is limited to its integrated bus.

The Intel Arc Graphics 2 Xe Mobile wins in efficiency-related metrics. Its 25 W TDP is drastically lower than the 2300 W TDP of the NVIDIA part. It has a higher boost clock at 2500 MHz versus 2267 MHz. It supports display output, while the NVIDIA part has none. It also supports the full set of consumer graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the NVIDIA part records no API support in the database. For any device that needs to render to a screen, the Intel part is the only one of the two that can do so at all.

The Intel part's 2 ray tracing cores provide at least some hardware ray tracing capability, while the NVIDIA part's ray tracing core count is not recorded, so no comparison can be made on that front. The Intel part's system-shared memory model means it can use whatever memory the host provides, which is flexible for integrated designs, but the database records no specific bandwidth figure for it.

The Verdict

Based strictly on the recorded data, these two products serve entirely different purposes. The NVIDIA Rubin GPU is a server accelerator with massive compute resources: 130.0 TFLOPS FP32, 896 tensor cores, 288 GB HBM4, and 22.1 TB/s bandwidth. It draws 2300 W and requires a 2700 W suggested PSU, occupies an SXM module slot, and has no display outputs. It is built for computation without any display or consumer graphics API support.

The Intel Arc Graphics 2 Xe Mobile is an integrated GPU for portable devices. It draws 25 W, uses system-shared memory, outputs to the built-in display of the host device, and supports the modern consumer graphics APIs. Its 256 shading units and 2 ray tracing cores are appropriate for an IGP class part, and its 2500 MHz boost clock is high for that category.

A user selecting a server-side compute accelerator would choose the NVIDIA Rubin GPU without hesitation, given its overwhelming throughput and memory advantages. A user designing or purchasing a portable device with integrated graphics would choose the Intel Arc Graphics 2 Xe Mobile, as the NVIDIA part cannot be integrated into such a device at all. The data does not support any scenario where these two parts compete for the same role.
