Intel Arc Graphics 128EU Mobile vs Lisuan Tech LX ULTRA Comparison

Intel Arc Graphics 128EU Mobile and Lisuan Tech LX ULTRA occupy opposing corners of the GPU landscape. The former is an integrated processor graphics solution built for mobility, while the latter is a discrete, dual-slot expansion card with dedicated memory. The recorded specifications show two designs with fundamentally different objectives, and the data supports a clear separation of use cases.

Where Each One Wins

The Lisuan Tech LX ULTRA dominates in raw computational throughput. Its shading units number 6144, exactly six times the 1024 found on the Intel Arc Graphics 128EU Mobile. This disparity carries through to texture mapping units, 192 versus 64, and raster output units, 96 versus 32. The FP32 performance rating of 24.58 TFLOPS for the Lisuan Tech part stands against 4.608 TFLOPS for the Intel integrated solution, a difference of roughly 5.3 times. FP16 throughput follows the same ratio, with 49.15 TFLOPS versus 9.216 TFLOPS, both expressed with a 2:1 ratio to FP32.

Memory bandwidth is another decisive win for the discrete card. The LX ULTRA carries 24 GB of GDDR6 memory across a 192-bit bus, achieving 432.0 GB/s. The Intel Arc Graphics 128EU Mobile uses system shared memory, with bandwidth listed as system dependent. No fixed figure exists for the integrated part, but the architecture ties performance directly to the host platform's memory subsystem, which in practice operates far below the dedicated GDDR6 bandwidth.

Pixel and texture rates tell the same story. The Lisuan Tech part outputs 192.0 GPixel/s and 384.0 GTexel/s. The Intel integrated GPU manages 72.00 GPixel/s and 144.0 GTexel/s. These numbers indicate the LX ULTRA sustains roughly 2.7 times the fill rate in both categories.

The Intel Arc Graphics 128EU Mobile wins in power efficiency and physical footprint. Its thermal design power is 28 W, compared to 225 W for the LX ULTRA. The integrated part occupies no expansion slot, listed as IGP, while the discrete card requires a dual-slot configuration measuring 268 mm in length, 112 mm in height, and 40 mm in width. The Intel solution requires no power connectors, while the LX ULTRA uses a single 16-pin connector and suggests a 550 W power supply.

Architecture Differences

The manufacturing processes diverge significantly. Intel builds the Arc Graphics 128EU Mobile on a 10 nm node at its own foundry. Lisuan Tech uses a 6 nm process from TSMC for the 7G105 chip. The smaller node gives the discrete part a density advantage, though transistor counts and die sizes are unrecorded for both products.

The Intel chip belongs to the Meteor Lake generation and uses the Xe-LPG architecture, part of the Arc Graphics-M family. The Lisuan Tech LX ULTRA uses the TrueGPU architecture from the 7G100 generation. These are separate design philosophies: Xe-LPG is Intel's scalable graphics architecture for integrated and entry-level discrete parts, while TrueGPU appears to target high-throughput compute and rendering workloads.

Clock behavior differs sharply. The Intel part lists a base clock of 300 MHz and a boost clock of 2250 MHz, showing a wide dynamic range typical of power-managed integrated GPUs. The Lisuan Tech part lists no base or boost clocks for the core, but its memory operates at 2250 MHz with 18 Gbps effective data rate. The absence of core clock data for the LX ULTRA means direct frequency comparison is impossible from the recorded information.

Memory architecture reflects the intended usage. Intel's integrated GPU shares system memory with no dedicated capacity, bus width, or fixed bandwidth. The LX ULTRA provides 24 GB of GDDR6 on a 192-bit interface. This dedicated memory pool allows the discrete card to avoid contention with CPU memory traffic, a structural advantage for sustained workloads.

API support shows differences in DirectX versions. The Intel part supports DirectX 12 (12_1), while the LX ULTRA supports DirectX 12 Ultimate (12_2). Vulkan support favors Intel at version 1.4 versus 1.3 for the Lisuan Tech card. OpenGL is identical at 4.6 for both.

The LX ULTRA provides four DisplayPort 1.4a outputs, while the Intel integrated GPU's display outputs are listed as portable device dependent, reflecting its role in laptops and compact systems. The bus interface also differs: Intel uses a ring bus for internal connectivity, while the Lisuan Tech card uses PCIe 4.0 x16 for external attachment.

The Verdict

The benchmark database shows zero head-to-head scores for these two products, and both carry a percentile ranking of 50 among all GPUs. With no measured performance data, the verdict must rest on the recorded specifications.

The Lisuan Tech LX ULTRA is the choice for workloads that demand maximum throughput: high-resolution rendering, compute-heavy applications, and scenarios where 24 GB of dedicated GDDR6 memory prevents spillover to system storage. Its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s position it for demanding visual tasks. The 432.0 GB/s memory bandwidth supports large textures and datasets without bottlenecking.

The Intel Arc Graphics 128EU Mobile suits systems where power consumption and physical space are constrained. At 28 W, it operates within the thermal envelope of a laptop or compact desktop. Its system shared memory eliminates the need for dedicated VRAM, reducing cost and complexity. The boost clock of 2250 MHz allows bursts of performance when needed, while the 300 MHz base clock preserves idle efficiency.

Neither part is a substitute for the other. The LX ULTRA cannot be installed in a system lacking a PCIe 4.0 x16 slot and sufficient cooling for a 225 W dual-slot card. The Intel integrated GPU cannot match the throughput of the discrete card for sustained professional workloads. Users requiring portability and low power draw will favor the Intel solution. Users requiring maximum compute and rendering capability will favor the Lisuan Tech card.

Head-to-Head Benchmarks

No head-to-head benchmark scores exist in the database for these two products. The wins count stands at zero for both items. This absence of measured data means all comparisons derive from the recorded specification sheets.

The largest numerical gap appears in shading units: 6144 versus 1024. This six-fold difference predicts proportional gains in shader-bound workloads, assuming similar instruction efficiency per unit. The FP32 figure of 24.58 TFLOPS versus 4.608 TFLOPS supports this expectation, showing 5.3 times the theoretical compute throughput.

Memory bandwidth shows an even more lopsided comparison, though the Intel side lacks a fixed number. The LX ULTRA's 432.0 GB/s dedicated bandwidth stands against system dependent performance for the Intel part. In integrated GPUs, shared memory bandwidth is typically a fraction of dedicated GDDR6 speeds, so the practical gap likely exceeds the compute ratio.

Pixel rate differences are moderate by comparison. The LX ULTRA's 192.0 GPixel/s versus 72.00 GPixel/s gives the discrete card a 2.7 times advantage. Texture rate follows the same 2.7 times ratio, with 384.0 GTexel/s against 144.0 GTexel/s. These smaller gaps suggest the fill rate pipeline scales less dramatically than the compute pipeline, likely due to the Intel part's relatively high boost clock of 2250 MHz compensating for fewer texture units.

The power envelope shows the inverse relationship. The LX ULTRA draws 225 W, exactly 8 times the 28 W TDP of the Intel integrated part. Performance per watt strongly favors the Intel solution: 4.608 TFLOPS divided by 28 W equals approximately 0.165 TFLOPS per watt, while the LX ULTRA achieves 24.58 TFLOPS divided by 225 W, approximately 0.109 TFLOPS per watt. The Intel part delivers about 1.5 times the compute efficiency per watt.

Release dates place these products far apart. The Intel Arc Graphics 128EU Mobile appeared on 2023-12-13, while the Lisuan Tech LX ULTRA is dated 2026-03-16. Both are listed as active production parts. The Intel chip has a predecessor in HD Graphics-M, while the LX ULTRA lists no predecessor.
