Architecture Differences

The Intel Arc 140V Mobile and the Lisuan Tech LX PRO represent fundamentally different design philosophies. The Intel part is a low-power integrated solution, part of the Lunar Lake chipset, using the Xe2-LPG architecture and belonging to the Arc Graphics-M (Lunar Lake) generation. Its predecessor is HD Graphics-M, and it was released in September 2024. The Lisuan Tech LX PRO is a standalone discrete GPU, built on the 7G105 chip with a TrueGPU architecture, part of the 7G100 generation, with a release date in March 2026.

The manufacturing processes differ notably. Intel uses a 3 nm node at TSMC with a die size of 172 mm². Lisuan Tech uses a 6 nm node at TSMC, with die size listed as unknown. The Intel GPU is an IGP, meaning it shares system memory and has no dedicated VRAM. The Lisuan card carries 24 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of dedicated bandwidth. The Intel part's memory bandwidth is system dependent, meaning it scales with the host platform's memory configuration rather than having a fixed value.

Compute resources diverge sharply. The Intel Arc 140V Mobile packs 1024 shading units, 64 texture mapping units, 32 ROPs, and 8 ray tracing cores. The Lisuan Tech LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs, but the data records no dedicated ray tracing cores. The Lisuan card's pixel rate is 192.0 GPixel/s versus 62.40 GPixel/s for the Intel part. Texture rate is 384.0 GTexel/s for Lisuan, compared to 124.8 GTexel/s for Intel.

Clock behavior also separates the two. The Intel Arc 140V Mobile has a base clock of 300 MHz and a boost clock of 1950 MHz. The Lisuan Tech LX PRO has no recorded base or boost clocks, but its memory clock is fixed at 2250 MHz with 18 Gbps effective data rate. The Intel GPU's memory clock is listed as system shared.

Physical and power characteristics reinforce the design gap. The Intel part has a 37 W TDP and is an IGP with no slot width or power connectors. The Lisuan card is dual-slot, measures 248 mm in length, 118 mm in height, and 48 mm in width, draws 225 W, and requires a 550 W suggested PSU with a single 16-pin connector. The Lisuan card supports PCIe 4.0 x16, while the Intel IGP uses the IGP bus interface. Display outputs differ as well: the Lisuan card provides 4x DisplayPort 1.4a, while the Intel IGP's outputs are portable device dependent.

The Verdict

The data shows two GPUs aimed at entirely different use cases. The Intel Arc 140V Mobile is an integrated solution for portable devices, with a 37 W TDP and system-shared memory. Its 50th percentile ranking among all GPUs, combined with 3.994 TFLOPS FP32, indicates it is positioned for light gaming and general graphics acceleration in thin-and-light laptops. The Lisuan Tech LX PRO, also at the 50th percentile, is a discrete card with 24.58 TFLOPS FP32 and 24 GB of GDDR6 memory, clearly targeting higher-resolution workloads and content creation.

For users relying on a laptop's integrated graphics, the Intel Arc 140V Mobile offers a modest but functional feature set: DirectX 12 Ultimate, Vulkan 1.4, and ray tracing cores. The Lisuan Tech LX PRO, by contrast, lacks recorded ray tracing cores but compensates with massive raw throughput, 432.0 GB/s bandwidth, and a 192-bit memory bus. The Lisuan card also supports a newer PCIe interface with PCIe 4.0 x16, while the Intel IGP is limited to the IGP bus.

Neither GPU has recorded benchmark scores in the database, so the analysis rests on specification-derived metrics. The Intel part is the only choice for ultra-portable systems where power draw and physical space are constrained. The Lisuan Tech LX PRO is the option for desktop builds requiring a discrete card with dedicated memory and high fill rates. The release dates also matter: Intel shipped in 2024, while Lisuan arrived in 2026, suggesting the Lisuan card benefits from newer design iterations.

Head-to-Head Benchmarks

The database records no direct benchmark scores for either GPU, so the head-to-head comparison relies on computed specifications. The most decisive gap appears in raw compute. The Lisuan Tech LX PRO produces 24.58 TFLOPS FP32, which is 6.16 times the Intel Arc 140V Mobile's 3.994 TFLOPS. In FP16, the Lisuan card reaches 49.15 TFLOPS versus 7.987 TFLOPS for the Intel part, again a 6.15 times advantage. These figures indicate that the Lisuan card can handle significantly heavier shader workloads.

Memory bandwidth is another major differentiator. The Lisuan Tech LX PRO offers 432.0 GB/s over a 192-bit GDDR6 bus. The Intel Arc 140V Mobile has system-dependent bandwidth, meaning it shares the host's memory controller. In any realistic configuration, the dedicated GDDR6 implementation provides far higher sustained throughput, which directly impacts texture streaming and high-resolution frame buffers.

Fill rates follow the same pattern. The Lisuan card achieves 192.0 GPixel/s, which is 3.08 times the Intel's 62.40 GPixel/s. Texture rate for Lisuan is 384.0 GTexel/s, exactly 3.08 times the Intel's 124.8 GTexel/s. These ratios stem from the Lisuan card having 3 times the ROPs (96 versus 32) and 3 times the TMUs (192 versus 64). The Lisuan card's advantage in shading units is even larger: 6144 versus 1024, a 6.0 times difference.

The Intel Arc 140V Mobile does hold advantages in certain areas. Its 3 nm process node is smaller than the Lisuan's 6 nm, which contributes to the Intel part's dramatically lower 37 W TDP versus 225 W. The Intel GPU also supports Vulkan 1.4, a newer version than the Lisuan card's Vulkan 1.3. Additionally, the Intel part includes 8 ray tracing cores, while the Lisuan card has no recorded ray tracing hardware. For applications that explicitly leverage ray tracing, the Intel IGP provides a feature that the Lisuan card lacks in the recorded data.

Clock speeds also differ, though the comparison is incomplete. The Intel Arc 140V Mobile has a base clock of 300 MHz and a boost of 1950 MHz. The Lisuan Tech LX PRO has no recorded base or boost clocks, so the only clock comparison available is the memory clock: the Lisuan card runs at 2250 MHz with 18 Gbps effective, while the Intel part's memory clock is system shared. The lack of recorded boost data for the Lisuan card makes a full clock-speed analysis impossible.

Power efficiency is starkly different. The Intel Arc 140V Mobile delivers 3.994 TFLOPS FP32 within a 37 W TDP, yielding approximately 0.108 TFLOPS per watt. The Lisuan Tech LX PRO delivers 24.58 TFLOPS FP32 at 225 W, yielding approximately 0.109 TFLOPS per watt. The efficiency figures are nearly identical, meaning the Lisuan card's performance advantage comes almost entirely from its much higher power envelope, not from architectural improvements. Both GPUs sit at the 50th percentile in the database's overall ranking, but that percentile masks the divergent target markets: one is a low-power IGP for mobility, the other a high-power discrete card for desktop systems.
