Intel Arc Graphics 48EU Mobile vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel Arc Graphics 48EU Mobile and the NVIDIA B300 SXM6 AC. The recorded data shows only a single OpenCL benchmark result for the NVIDIA part, with no corresponding benchmark entry for the Intel iGPU. Consequently, a comparative performance analysis based on measured outputs is not possible from the available measurements.

What the data does provide is a clear positioning of the NVIDIA B300 SXM6 AC within its own performance class. The Geekbench OpenCL score of 369,831 places it at the 100th percentile across all GPUs in the database, meaning it outperforms every other recorded part. Its average benchmark score is likewise 369,831, reflecting the single benchmark entry. Relative to its nearest rivals, the B300 leads the NVIDIA B200 by 7%, the NVIDIA H200 NVL by 10.4%, the AMD Instinct MI300X by 16.3%, and the NVIDIA L40S by 25%. These deltas are substantial, particularly the gap over the L40S, which represents a quarter of that GPU's score. The B300's percentile ranking confirms that, on the basis of recorded OpenCL performance, it sits at the top of the database hierarchy.

For the Intel Arc Graphics 48EU Mobile, the database records an average benchmark score of 0 and a percentile rank of 50. The absence of any benchmark entries means the score of 0 is not a performance measurement but rather a placeholder indicating no recorded results. The percentile of 50 is a neutral midpoint, reflecting the lack of data rather than a performance verdict. No nearest rivals are listed for the Intel part, further underscoring that no comparative benchmark data exists for it in the database.

Architecture Differences

The two GPUs represent fundamentally different design philosophies and market segments. The Intel Arc Graphics 48EU Mobile is an integrated graphics processor built on the Meteor Lake chip, using the Xe-LPG architecture. It belongs to the Arc Graphics-M (Meteor Lake) generation and is manufactured by Intel on a 10 nm process node. The NVIDIA B300 SXM6 AC is a discrete server accelerator built on the GB110 chip, using the Blackwell Ultra architecture. It belongs to the Server Blackwell (Bxx) generation and is manufactured by TSMC on a 5 nm process node. The process node difference alone indicates a significant generational gap in manufacturing technology.

The transistor counts are starkly different. The NVIDIA B300 packs 208,000 million transistors on a die size of 1628 mm², yielding a transistor density of 127.8M per mm². The Intel part has no recorded transistor count or die size in the database, but as an integrated GPU sharing a die with a CPU, its scale is inherently smaller. The B300's die is a massive monolithic piece of silicon, among the largest in the industry, while the Intel iGPU is a fraction of a heterogeneous chip.

Memory subsystems diverge completely. The Intel Arc Graphics 48EU Mobile uses system-shared memory, with its type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." This means it draws from the host system's main memory, with no dedicated VRAM. The NVIDIA B300, by contrast, features 288 GB of HBM3e memory on a 8192-bit bus, delivering 8.19 TB/s of bandwidth. This is a dedicated, ultra-wide memory interface designed for bandwidth-intensive server workloads, a category the Intel iGPU does not participate in.

Compute resources are equally disparate. The Intel part has 384 shading units, 24 texture mapping units (TMUs), and 8 render output units (ROPs). The NVIDIA B300 has 18,944 shading units, 592 TMUs, and 24 ROPs. The NVIDIA part also includes 592 tensor cores, while the Intel part has none recorded. Pixel rates are 14.40 GPixel/s for Intel versus 48.77 GPixel/s for NVIDIA. Texture rates are 43.20 GTexel/s versus 1,202.9 GTexel/s. FP32 compute is 1,382.4 GFLOPS (1.38 TFLOPS) for Intel versus 76.99 TFLOPS for NVIDIA, a ratio of roughly 55 to 1. FP16 performance is 2.765 TFLOPS for Intel (at a 2:1 ratio) versus 76.99 TFLOPS for NVIDIA (at 1:1), meaning the NVIDIA part achieves full-rate FP16 without a penalty.

Clock speeds show a different relationship. The Intel iGPU has a base clock of 300 MHz and a boost clock of 1800 MHz. The NVIDIA B300 has a base clock of 1665 MHz and a boost clock of 2032 MHz. While the NVIDIA boost clock is only modestly higher, the base clock is over five times higher, reflecting a sustained, high-frequency operating profile for the server part versus the power-constrained integrated GPU.

Power and physical characteristics diverge as well. The Intel part has a TDP of 28 W and is an IGP (integrated graphics processor) with a Ring Bus interface. The NVIDIA B300 has a TDP of 1100 W, is an SXM Module with a PCIe 6.0 x16 bus interface, and has a suggested PSU of 1500 W. The Intel part's display outputs are "Portable Device Dependent," meaning it relies on the host device for display connectivity. The NVIDIA B300 has no display outputs at all, as it is a compute accelerator, not a graphics card.

API support is another differentiator. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA B300 lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for client-side graphics APIs but rather for compute and AI workloads via CUDA and other server-side frameworks.

Where Each One Wins

The NVIDIA B300 SXM6 AC wins decisively in every category where recorded data exists. Its OpenCL benchmark score of 369,831 places it at the 100th percentile, far above the Intel part's unrecorded score of 0. It leads all four nearest rivals by margins from 7% to 25%, confirming its position at the top of the database. Its compute resources are on a different scale entirely: 18,944 shading units versus 384, 592 TMUs versus 24, and 592 tensor cores versus none. FP32 compute of 76.99 TFLOPS is roughly 55 times the Intel part's 1,382.4 GFLOPS. FP16 performance is equally lopsided at 76.99 TFLOPS versus 2.765 TFLOPS. Memory bandwidth of 8.19 TB/s from 288 GB of HBM3e is simply unavailable to an integrated GPU that shares system memory. The B300 is built for sustained, high-throughput compute in server environments, with a 1100 W TDP and a 1500 W suggested PSU, and it uses a PCIe 6.0 x16 interface. Its architecture, Blackwell Ultra on a 5 nm TSMC process, represents a recent, high-end server design.

The Intel Arc Graphics 48EU Mobile wins in the categories of power efficiency and integration. Its 28 W TDP is a fraction of the B300's 1100 W, making it suitable for portable devices where power budgets are tight. It is an IGP with a Ring Bus interface, designed to be part of a Meteor Lake system-on-chip rather than a standalone accelerator. Its display outputs are portable-device dependent, meaning it can drive displays on laptops and other mobile hardware, while the B300 has no display outputs at all. The Intel part supports standard graphics APIs including DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, whereas the B300 lists N/A for all of these. It also has a lower base clock of 300 MHz versus 1665 MHz, which is a disadvantage in raw speed but reflects its power-constrained design. The Intel iGPU is the only one of the two that can render graphics to a screen in a client device.

The use-case split is stark. The Intel Arc Graphics 48EU Mobile serves as an integrated graphics solution for mobile computing, handling display output and light rendering workloads within a 28 W envelope. The NVIDIA B300 SXM6 AC serves as a server-grade compute accelerator for AI, HPC, and data center workloads, delivering extreme FP32 and FP16 throughput with massive memory capacity and bandwidth. The database shows no overlap in benchmark results, no shared API support, and no comparable form factor. Each part wins in its respective domain, and the recorded data confirms that the B300 is the dominant performer in raw compute while the Intel iGPU holds the advantage in integration and power efficiency.
