Intel Arc 140T Mobile vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The Intel Arc 140T Mobile and NVIDIA B300 SXM6 AC occupy entirely different segments of the graphics hardware spectrum, and the recorded data reflects this split clearly. The Arc 140T is an integrated graphics processor (IGP) within Intel's Arrow Lake-H mobile platform, while the B300 SXM6 AC is a server-class accelerator module built on NVIDIA's Blackwell Ultra architecture.

In terms of raw compute throughput, the B300 SXM6 AC dominates. The B300 delivers 76.99 TFLOPS of FP32 performance, compared to the Arc 140T's 4.813 TFLOPS. That represents a 16x advantage for the NVIDIA part in single-precision floating-point workloads. The gap widens further in FP16 operations: the B300 provides 76.99 TFLOPS with a 1:1 ratio, while the Arc 140T reaches 9.626 TFLOPS using a 2:1 ratio, meaning the B300 is roughly 8x faster in half-precision tasks as well.

Texture processing tells a similar story. The B300's texture rate is 1,202.9 GTexel/s against the Arc 140T's 150.4 GTexel/s, an 8x difference. The NVIDIA module also carries 592 tensor cores, which the Intel part lacks entirely, making the B300 the only option here for tensor-accelerated workloads.

However, the Arc 140T posts a higher pixel rate. The Intel IGP reaches 75.20 GPixel/s, while the B300 manages 48.77 GPixel/s. This is notable because the B300 has far more shading units (18,944 versus 1,024) but only 24 ROPs, while the Arc 140T has 32 ROPs. The higher pixel throughput indicates the Intel part is better suited for rasterization tasks where fill-rate matters, such as lower-resolution gaming or basic display output.

The B300's memory subsystem is in a different class entirely. It uses 288 GB of HBM3e memory across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The Arc 140T uses system-shared memory with system-dependent bandwidth, which means its performance is tied to the host laptop's RAM configuration rather than a dedicated memory pool. In memory-bound workloads, the B300's dedicated high-bandwidth memory provides an enormous practical advantage.

The OpenCL benchmark data only exists for the B300, with a Geekbench OpenCL score of 369,831. This places it at the 100th percentile against all GPUs in the database, meaning it outperforms every other recorded graphics processor. Its nearest rivals in the database include the NVIDIA B200 at 345,482 (7% lower), the NVIDIA H200 NVL at 334,891 (10.4% lower), the AMD Instinct MI300X at 317,994 (16.3% lower), and the NVIDIA L40S at 295,763 (25% lower). The Arc 140T has no recorded benchmark scores and sits at the 50th percentile, indicating it performs at the median level for all GPUs, though without direct head-to-head measurements in the database.

The Verdict

The data supports a clear split between these two products. The NVIDIA B300 SXM6 AC is a compute-oriented accelerator for server deployments, data centers, and AI training or inference tasks. Its 76.99 TFLOPS FP32, 592 tensor cores, 288 GB HBM3e memory, and 8.19 TB/s bandwidth position it as a top-tier solution for workloads that demand massive parallel throughput and memory capacity. The 100th percentile ranking and the 7-25% margins over its nearest rivals confirm its performance leadership within the database.

The Intel Arc 140T Mobile is an integrated graphics solution for laptops, drawing 35 W and using system memory. Its 50th percentile ranking and lack of dedicated benchmark scores indicate it delivers mainstream-level graphics performance suitable for everyday computing, light gaming, and media playback. The 35 W TDP versus the B300's 1100 W TDP highlights the fundamental difference in power envelopes, with the Intel part designed for battery-powered mobility rather than rack-mounted compute density.

There is no overlap in intended use. The B300 suits organizations running large-scale compute workloads, while the Arc 140T serves mobile users who need basic GPU capabilities without a discrete graphics card. The B300's 1500 W suggested PSU and SXM module form factor make it incompatible with consumer systems, while the Arc 140T's IGP bus interface means it cannot be used outside its host processor.

Architecture Differences

The two chips come from different architectural lineages. The Intel Arc 140T uses the Xe-LPG+ architecture built on Intel's Arrow Lake-H chip, part of the Arc Graphics-M (Arrow Lake) generation. It is fabricated on a 5 nm process at TSMC. The NVIDIA B300 uses the Blackwell Ultra architecture on the GB110 chip, also fabricated on a 5 nm process at TSMC, but within the Server Blackwell (Bxx) generation.

The B300 carries 208,000 million transistors on a 1628 mm² die, resulting in a transistor density of 127.8M per mm². The Arc 140T's transistor count and die size are listed as unknown in the database, so no direct comparison is possible on those figures.

The Intel part integrates 8 ray-tracing cores, which the B300 does not list any RT cores for. This suggests the Arc 140T is designed to handle DirectX ray-traced content, while the B300 focuses on compute and tensor workloads instead. The B300's 592 tensor cores are its primary processing advantage, and the lack of RT cores indicates NVIDIA's server part prioritizes AI and scientific computing over real-time graphics rendering.

The Arc 140T supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it fully capable for modern gaming APIs. The B300 lists N/A for DirectX, OpenGL, and Vulkan, confirming it is not intended for conventional graphics API workloads. Its display outputs are listed as "No outputs," meaning it cannot drive a monitor directly. The Arc 140T's display outputs are "Portable Device Dependent," reflecting its role as an integrated GPU in mobile systems.

The B300 uses a PCIe 6.0 x16 bus interface, while the Arc 140T uses an IGP interface. This difference reflects the B300's status as a discrete accelerator module that plugs into a server motherboard, versus the Intel part being embedded within the processor package.

Specification Differences

The specification tables show substantial differences across nearly every field. The B300 has 18,944 shading units versus the Arc 140T's 1,024, an 18.5x difference. Texture mapping units number 592 on the B300 against 64 on the Arc. ROPs are 32 on the Intel part versus 24 on the NVIDIA module, which contributes to the Arc's higher pixel rate despite its smaller overall design.

Clock speeds differ significantly. The Arc 140T has a base clock of 300 MHz and a boost clock of 2350 MHz. The B300 operates at a 1665 MHz base clock and 2032 MHz boost clock. The NVIDIA part runs at a higher floor but a lower ceiling, reflecting a design tuned for sustained throughput rather than burst performance.

Memory configurations are entirely different. The Arc 140T uses system-shared memory with system-shared type, bus width, and system-dependent bandwidth. The B300 uses 288 GB of HBM3e memory with an 8192-bit bus and 8.19 TB/s bandwidth. The memory clock for the B300 is 2000 MHz with 8 Gbps effective speed. The Arc's memory clock is also listed as system-shared.

Power consumption shows the largest practical gap. The Arc 140T has a 35 W TDP, suitable for thin-and-light laptops. The B300 has a 1100 W TDP and requires a 1500 W suggested PSU, indicating it needs substantial cooling and power delivery infrastructure. The B300 uses an SXM module slot width, while the Arc uses an IGP slot width.

The release dates place the Arc 140T first at January 2025, with the B300 following in September 2025. The Arc's predecessor is listed as HD Graphics-M, while the B300's predecessor is Server Hopper, and its successor is Server Rubin. Both are marked as Active production status.

Where Each One Wins

The NVIDIA B300 SXM6 AC wins decisively in compute-intensive applications. Its 76.99 TFLOPS FP32 and FP16 performance, 592 tensor cores, 288 GB HBM3e memory, and 8.19 TB/s bandwidth make it the clear choice for AI training, scientific simulation, and large-scale data processing. The 100th percentile ranking and 7-25% margins over its nearest competitors confirm that it leads the database in raw benchmark performance. The 1,202.9 GTexel/s texture rate also positions it strongly for workloads involving heavy texture sampling, such as certain rendering tasks or image processing pipelines.

The Intel Arc 140T Mobile wins in pixel fill-rate and mobile integration. Its 75.20 GPixel/s exceeds the B300's 48.77 GPixel/s, giving it an advantage in rasterization-heavy scenarios at lower resolutions. The 35 W TDP and IGP form factor mean it can operate within a laptop's thermal and power budget, whereas the B300 requires external power delivery and liquid or high-airflow cooling. The Arc supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, enabling compatibility with consumer games and applications. The B300 supports none of these APIs, so it cannot run standard graphics software.

For ray-traced content, the Arc 140T's 8 RT cores provide dedicated hardware support, while the B300 has none listed. This makes the Intel part functional for DirectX ray tracing workloads, though its overall performance is far lower than dedicated discrete GPUs. The B300's lack of RT cores indicates NVIDIA reserves that functionality for its consumer and professional graphics lines, not its server compute accelerators.

The 50th percentile ranking for the Arc 140T places it exactly at the median of all GPUs in the database, suggesting it performs adequately for its integrated class but does not compete with discrete options. The B300's 100th percentile ranking means it outperforms all other recorded GPUs, including several high-end server accelerators.

In practical terms, the B300 suits organizations deploying rack-mounted servers for compute-heavy tasks. The Arc 140T suits laptop manufacturers building machines that need basic GPU capabilities without a separate graphics card. The 1100 W TDP difference means these products will never appear in the same system, and the data confirms they serve mutually exclusive markets.
