Intel Arc 140T Mobile vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the Intel Arc 140T Mobile or the Lisuan Tech LX ULTRA. Both entries show an average benchmark score of zero, and no head-to-head benchmark results are available in the recorded data. The absence of measured performance data means a direct numerical comparison of real-world application performance cannot be established from our measurements.

What the data does provide is the theoretical compute ceiling for each part, derived from their recorded specifications. The Lisuan Tech LX ULTRA delivers 24.58 TFLOPS of FP32 throughput, while the Intel Arc 140T Mobile delivers 4.813 TFLOPS. This places the LX ULTRA at roughly 5.1 times the FP32 compute capacity of the Intel part, a substantial gap in raw shader throughput. The FP16 figures follow the same proportional relationship: the LX ULTRA reaches 49.15 TFLOPS against 9.626 TFLOPS for the Arc 140T Mobile, with both parts using a 2:1 ratio.

Texture and pixel throughput tell a similar story. The LX ULTRA records 384.0 GTexel/s of texture fill rate and 192.0 GPixel/s of pixel fill rate. The Arc 140T Mobile records 150.4 GTexel/s and 75.20 GPixel/s respectively. The LX ULTRA is ahead by a factor of 2.55 in texture rate and 2.55 in pixel rate, which reflects its larger allocation of texture mapping units and render output units.

Memory bandwidth is where the separation becomes most pronounced. The LX ULTRA uses 24 GB of GDDR6 memory on a 192-bit bus, producing 432.0 GB/s of bandwidth. The Arc 140T Mobile uses system shared memory with a bus width and bandwidth listed as system dependent, meaning its memory performance is determined by the host platform rather than a fixed specification. The LX ULTRA's dedicated memory pool provides a fixed, measurable bandwidth figure that the Intel part cannot match under any platform configuration recorded in the database.

The power envelope differs sharply. The LX ULTRA carries a TDP of 225 W and requires a 550 W suggested power supply, using a single 16-pin power connector. The Arc 140T Mobile is rated at 35 W and is an integrated graphics processor with no power connectors. The LX ULTRA consumes 6.4 times the power of the Intel part, which is consistent with its larger compute and memory resources.

Both parts share the same DirectX support at 12 Ultimate (12_2) and OpenGL 4.6. The Arc 140T Mobile supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The Intel part includes 8 ray tracing cores; the LX ULTRA lists no ray tracing cores in its recorded data. The LX ULTRA has 6144 shading units, 192 texture mapping units, and 96 render output units. The Arc 140T Mobile has 1024 shading units, 64 texture mapping units, and 32 render output units.

Neither part has any nearest rivals recorded in the database, and both sit at the 50th percentile versus all GPUs. With no benchmark scores, the percentile field carries no comparative weight; it simply reflects the absence of measured data rather than a performance ranking.

The Verdict

The data indicates two products built for entirely different roles. The Intel Arc 140T Mobile is an integrated GPU with a 35 W TDP, system shared memory, and a compact IGP slot width. The Lisuan Tech LX ULTRA is a dual-slot discrete card with 24 GB of dedicated GDDR6 memory, a 225 W TDP, and a PCIe 4.0 x16 interface.

From the recorded specifications, the LX ULTRA is the dominant part in every fixed numerical category: FP32 compute, FP16 compute, texture fill rate, pixel fill rate, memory capacity, memory bandwidth, shading units, texture mapping units, and render output units. It is also the only one of the two with a defined memory clock (2250 MHz, 18 Gbps effective) and a fixed memory bus width (192 bit).

The Arc 140T Mobile's advantages are limited to the categories where the LX ULTRA has no recorded data or where the Intel part holds a positional edge. It includes ray tracing cores (8 of them), while the LX ULTRA lists none. It supports Vulkan 1.4, one version newer than the LX ULTRA's Vulkan 1.3. It draws far less power at 35 W versus 225 W, and it requires no external power connector. It also carries a 5 nm process node against the LX ULTRA's 6 nm node, though both are fabricated by TSMC.

The verdict from the data is straightforward: the LX ULTRA is the higher-performance part by every measurable compute and memory metric. The Arc 140T Mobile is the lower-power integrated solution with a smaller process node and ray tracing support. There is no benchmark data to suggest the Intel part can compensate for its 5.1 times FP32 deficit through architectural efficiency. The recorded numbers do not support that conclusion.

Where Each One Wins

The Lisuan Tech LX ULTRA wins in raw compute throughput. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 figures place it far ahead of the Arc 140T Mobile's 4.813 and 9.626 TFLOPS. Workloads that scale with shader count, such as high-resolution rendering or heavy compute workloads, have a clear advantage on the LX ULTRA based on the recorded data.

The LX ULTRA also wins in memory-intensive scenarios. Its 432.0 GB/s of dedicated GDDR6 bandwidth is a fixed value, whereas the Arc 140T Mobile's bandwidth is system dependent. Applications that require frequent large data transfers, such as texture streaming or large dataset processing, have a measurable bandwidth advantage on the discrete card.

The LX ULTRA wins in texture and pixel throughput. Its 384.0 GTexel/s and 192.0 GPixel/s are 2.55 times the corresponding figures for the Intel part. This indicates an advantage in fill-rate-bound rendering tasks, where the number of textured pixels or depth operations per second limits performance.

The Intel Arc 140T Mobile wins in power efficiency by the numbers available. At 35 W, it uses a fraction of the LX ULTRA's 225 W budget. For platforms constrained by thermal or power limits, such as thin portable devices, the Intel part is the only viable option given the LX ULTRA's dual-slot size and 550 W suggested power supply.

The Arc 140T Mobile wins in ray tracing capability, as it is the only one of the two with recorded ray tracing cores. The LX ULTRA has none listed. The Intel part also holds a minor API advantage with Vulkan 1.4 support against Vulkan 1.3 on the LX ULTRA.

The Arc 140T Mobile wins on integration. It is an IGP with no power connectors and a system shared memory configuration, meaning it requires no additional board space or power delivery hardware. The LX ULTRA requires a dual-slot footprint, a 16-pin power connector, and a 550 W power supply.
