Intel Arc 140V Mobile vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc 140V Mobile and the NVIDIA B300 SXM6 AC. The only available performance measurement belongs to the NVIDIA B300 SXM6 AC, which posts a Geekbench OpenCL score of 369,831. This score places the GPU at the 100th percentile among all GPUs in the database, indicating it sits at the absolute top of the performance distribution. The Intel Arc 140V Mobile, by contrast, holds a 50th percentile ranking, placing it squarely in the middle of the field. With no overlapping benchmark results, a direct numeric comparison of compute throughput is not possible from the database. What is clear is the enormous gulf in performance class between the two parts, one a server accelerator aimed at maximum compute density and the other an integrated graphics solution for mobile devices.

The NVIDIA B300 SXM6 AC's OpenCL result of 369,831 becomes more meaningful when examined against its nearest recorded rivals. The database shows the B300 running 7% ahead of the NVIDIA B200, which scores 345,482. It also leads the NVIDIA H200 NVL (334,891) by 10.4%, the AMD Instinct MI300X (317,994) by 16.3%, and the NVIDIA L40S (295,763) by 25%. These deltas confirm that the B300 does not merely occupy the top percentile; it extends a substantial margin over the next-best accelerators in the same server class. The Intel Arc 140V Mobile has no recorded rivals in the database, so its relative position cannot be established beyond the percentile figure.

Where Each One Wins

The Intel Arc 140V Mobile wins in portability and power efficiency by default, as it is an integrated graphics processor (IGP) with a 37 W TDP. Its system-shared memory architecture means it draws no dedicated video memory, and its 3 nm process node from TSMC represents the most advanced manufacturing technology in this comparison. The GPU delivers 3.994 TFLOPS of FP32 performance, 62.40 GPixel/s pixel rate, and 124.8 GTexel/s texture rate. These figures suit lightweight graphical workloads, multimedia playback, and casual gaming on a mobile platform. The presence of 8 ray tracing cores and DirectX 12 Ultimate (12_2) support indicates the hardware is capable of modern graphics features, though at a fundamentally lower throughput scale than the server part.

The NVIDIA B300 SXM6 AC wins in raw compute, memory capacity, and bandwidth. Its 288 GB of HBM3e memory on an 8192-bit bus delivers 8.19 TB/s of bandwidth, a figure that dwarfs any system-shared memory arrangement. The FP32 throughput of 76.99 TFLOPS is roughly 19 times higher than the Intel part's 3.994 TFLOPS, and the FP16 figure is identical at 76.99 TFLOPS with a 1:1 ratio, whereas the Intel GPU halves its FP16 rate to 7.987 TFLOPS. The B300 also carries 592 tensor cores, a feature entirely absent from the Intel IGP's specification list. The server accelerator's 208,000 million transistors on a 1628 mm² die underscore its purpose as a massive compute engine. For AI inference, scientific simulation, and large-scale data processing, the B300 dominates. For embedded mobile graphics, the Arc 140V is the only viable option in this pairing.

Architecture Differences

The two GPUs come from completely different architectural lineages. The Intel Arc 140V Mobile uses the Xe2-LPG architecture on the Lunar Lake chip, belonging to the Arc Graphics-M (Lunar Lake) generation. It is fabricated on a 3 nm process at TSMC with a die size of 172 mm². The NVIDIA B300 SXM6 AC employs the Blackwell Ultra architecture on the GB110 chip, part of the Server Blackwell (Bxx) generation, built on a 5 nm process at TSMC with a 1628 mm² die and 208,000 million transistors. The transistor density figure for the B300 is 127.8M per mm², while the Intel part's density is recorded as unknown.

Core configurations differ dramatically. The Intel GPU has 1024 shading units, 64 texture mapping units, 32 ROPs, and 8 ray tracing cores. It has no tensor cores listed. The NVIDIA part has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores, with no ray tracing core count provided. The pixel rate of the Intel part (62.40 GPixel/s) actually exceeds the NVIDIA part's 48.77 GPixel/s, a consequence of the B300's lower ROP count relative to its massive shader array. Texture rate favors the B300 heavily at 1,202.9 GTexel/s versus 124.8 GTexel/s.

Memory architecture is another fundamental split. The Intel Arc 140V uses system-shared memory with a system-dependent bandwidth, while the B300 carries dedicated 288 GB HBM3e on an 8192-bit bus. Clock behavior also differs: the Intel GPU runs at a 300 MHz base and 1950 MHz boost, while the B300 runs at 1665 MHz base and 2032 MHz boost, with its memory at 2000 MHz (8 Gbps effective). The API support separates them further. Intel lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. NVIDIA's B300 lists N/A for DirectX, OpenGL, and Vulkan, confirming its role as a compute-focused accelerator without graphics output. The B300 also has no display outputs, whereas the Intel IGP's outputs are portable-device dependent.
