Intel Arc Graphics 1 Xe Mobile vs NVIDIA B300 SXM6 AC Comparison

Intel Arc Graphics 1 Xe Mobile and NVIDIA B300 SXM6 AC sit at opposite ends of the GPU spectrum, one a low-power integrated solution for portable devices, the other a massive server accelerator. The recorded data shows no direct head-to-head benchmark results between them, so the comparison relies entirely on their respective specifications and the B300's available benchmark data.

Head-to-Head Benchmarks

The database contains no overlapping benchmark scores for these two products. The Intel Arc Graphics 1 Xe Mobile has no recorded benchmark entries, while the NVIDIA B300 SXM6 AC carries a single Geekbench OpenCL score of 369,831. This places the B300 in the 100th percentile among all GPUs in the database, meaning it outperforms every other recorded graphics processor.

Comparing the B300 to its nearest rivals provides context for its performance level. The B300 sits 7% ahead of the NVIDIA B200, which averages 345,482 points. It leads the NVIDIA H200 NVL by 10.4%, with that part scoring 334,891. Against the AMD Instinct MI300X, the B300 is 16.3% ahead, as the AMD part averages 317,994. The gap widens to 25% versus the NVIDIA L40S, which scores 295,763.

For the Intel Arc Graphics 1 Xe Mobile, the database records no benchmark scores and no nearest rivals, so no direct performance comparisons are possible. The Intel part does have an average benchmark score of zero, which reflects the absence of test data rather than actual performance. Its percentile versus all GPUs is 50, a neutral placeholder in the absence of measurements.

The raw compute figures show the scale of the gap. The B300 delivers 76.99 TFLOPS of FP32 performance, while the Intel part offers 588.8 GFLOPS. That is a difference of roughly 130 times in raw floating-point throughput. Pixel throughput shows the same pattern: the B300 renders 48.77 GPixel/s, the Intel part 9.200 GPixel/s. Texture rate puts the B300 at 1,202.9 GTexel/s versus 18.40 GTexel/s for the Intel graphics.

Where Each One Wins

The NVIDIA B300 SXM6 AC wins decisively in every compute-oriented category. Its FP32 throughput of 76.99 TFLOPS targets massive parallel workloads such as AI training, scientific simulation, and high-performance computing. The FP16 rate of 76.99 TFLOPS with 1:1 ratio indicates it processes half-precision data at the same speed as single-precision, which suits machine learning inference and training. The 592 tensor cores provide dedicated hardware for matrix operations common in neural networks.

Memory capacity and bandwidth favor the B300 heavily. It carries 288 GB of HBM3e across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. This supports very large models and datasets that exceed the memory capacity of typical workstation GPUs. The system memory bandwidth for the Intel part is marked as system dependent, and its memory size is shared with the host system, meaning it has no dedicated VRAM.

The Intel Arc Graphics 1 Xe Mobile wins in power efficiency and integration. Its 25 W TDP allows it to operate within the thermal envelope of a laptop or portable device, whereas the B300 demands a 1100 W TDP and a 1500 W suggested PSU. The Intel part is an IGP with no power connectors, and it outputs to portable device dependent displays. The B300 has no display outputs at all, making it unsuitable for any role that requires driving a monitor.

The Intel part also claims API support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B300 lists N/A for all three APIs. For consumer graphics workloads such as gaming or content creation, the Intel part has functional API coverage. The B300 lacks any consumer graphics API support, reinforcing its server-only role.

Architecture Differences

The Intel Arc Graphics 1 Xe Mobile uses the Xe3-LPG architecture on Intel's Wildcat Lake chip, built on a 3 nm process at Intel foundry. This is the latest generation of Intel's mobile graphics, branded under Arc Graphics-M. The architecture targets low power consumption and integration, with the GPU sharing system memory rather than using dedicated VRAM. It includes 1 ray tracing core, indicating some support for hardware-accelerated ray tracing.

The NVIDIA B300 SXM6 AC uses the Blackwell Ultra architecture on the GB110 chip, manufactured by TSMC on a 5 nm process. The chip contains 208,000 million transistors on a 1628 mm² die, giving a transistor density of 127.8 million per square millimeter. Blackwell Ultra is NVIDIA's server-grade architecture, designed for maximum compute throughput in data center environments. It omits ray tracing cores from its specification, instead devoting die area to 592 tensor cores.

The Intel part has 128 shading units, 8 texture mapping units, and 4 render output units. These are modest counts consistent with an integrated GPU. The B300 has 18,944 shading units, 592 TMUs, and 24 ROPs. The difference in shading units alone is 148 times.

Clock behavior differs significantly. The Intel part has a base clock of 300 MHz and a boost of 2300 MHz, a wide dynamic range that lets it idle at very low power and ramp up when needed. The B300 has a base clock of 1665 MHz and a boost of 2032 MHz, a much narrower range that reflects its constant high-power operation. Memory clock for the Intel part is system shared, while the B300 runs its HBM3e at 2000 MHz with 8 Gbps effective data rate.

Specification Differences

The two products differ in nearly every specification field recorded in the database. The B300 uses a 5 nm process at TSMC, the Intel part uses 3 nm at Intel. The B300 has a known transistor count of 208,000 million and a die size of 1628 mm²; the Intel part has unknown values for both. The B300 chip is 127.8 million transistors per square millimeter, the Intel part has no density figure.

Memory separates them completely. The B300 has 288 GB of HBM3e on an 8192-bit bus with 8.19 TB/s bandwidth. The Intel part uses system shared memory of system shared type, with system dependent bandwidth. The B300 lists its memory clock as 2000 MHz 8 Gbps effective; the Intel part lists system shared.

Compute resources show the largest gaps. Shading units: 18,944 versus 128. TMUs: 592 versus 8. ROPs: 24 versus 4. Tensor cores: 592 for the B300, none listed for the Intel part. Ray tracing cores: 1 for the Intel part, none listed for the B300. FP32 output: 76.99 TFLOPS versus 588.8 GFLOPS. FP16 output: 76.99 TFLOPS versus 1,177.6 GFLOPS. Pixel rate: 48.77 GPixel/s versus 9.200 GPixel/s. Texture rate: 1,202.9 GTexel/s versus 18.40 GTexel/s.

Power and form factor differ completely. The B300 is an SXM module with a 1100 W TDP and a 1500 W suggested PSU. The Intel part is an IGP with a 25 W TDP and no power connectors. The B300 uses a PCIe 6.0 x16 bus interface, the Intel part uses IGP. The B300 has no display outputs, the Intel part has portable device dependent outputs.

Release timing also differs. The B300 was released on 2025-09-10, with the Intel part following on 2026-04-15. The B300 has a predecessor named Server Hopper and a successor named Server Rubin. The Intel part lists HD Graphics-M as its predecessor and no successor.

The Verdict

The data points to two entirely different products for entirely different roles. The NVIDIA B300 SXM6 AC is a server accelerator with 288 GB of HBM3e, 8.19 TB/s of bandwidth, 76.99 TFLOPS of FP32 throughput, and 592 tensor cores. It ranks in the 100th percentile of all GPUs, leads its nearest rival by 7%, and carries a 1100 W TDP. This part targets data center workloads where maximum compute density matters and power draw is secondary.

The Intel Arc Graphics 1 Xe Mobile is an integrated GPU for portable devices. It draws 25 W, uses system shared memory, and provides basic API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 128 shading units and 1 ray tracing core suit light graphics tasks, media playback, and casual gaming on laptops. Its 3 nm process at Intel foundry indicates a focus on efficiency rather than raw performance.

Anyone building a server for AI or scientific workloads should choose the B300 based on its benchmark dominance and memory capacity. Anyone selecting hardware for a portable consumer device should choose the Intel part, as the B300 has no display outputs and cannot run consumer graphics APIs. The two GPUs do not compete in the same market segment, and the recorded data confirms no overlap in their intended use cases.
