The Verdict

The recorded data positions these two products at opposite ends of the graphics spectrum. The Intel Arc Graphics 128EU Mobile is an integrated solution with a 28 W TDP, designed for portable devices where space and power are constrained. The Lisuan Tech LX 7G100 is a 225 W dual-slot discrete card with dedicated 12 GB GDDR6 memory, aimed at workloads that demand sustained throughput.

For users constrained to a mobile platform with no expansion capability, the Intel part is the only option in this comparison, and its 4.608 TFLOPS FP32 throughput is sufficient for mainstream tasks. The Lisuan Tech LX 7G100, delivering 24.58 TFLOPS FP32, offers 5.3 times the raw compute of the Intel part, along with a 192-bit memory bus and 432.0 GB/s bandwidth versus system-shared memory. The data clearly shows that any application sensitive to memory bandwidth or heavy parallel compute will favor the Lisuan Tech card.

The Intel Arc Graphics 128EU Mobile holds advantages in API support, specifically Vulkan 1.4 versus Vulkan 1.3, and its 28 W power envelope. The Lisuan Tech LX 7G100 counters with DirectX 12 Ultimate (12_2) support, which the Intel part lacks. The choice is straightforward: the Intel IGP serves integrated mobile use cases, while the Lisuan Tech card serves desktop performance needs.

Head-to-Head Benchmarks

The benchmark database shows no recorded head-to-head benchmark entries for these two products, and neither has an average benchmark score or rival list populated. However, the specification data provides a basis for direct comparison across compute and memory metrics.

The most significant gap appears in FP32 floating-point performance. The Lisuan Tech LX 7G100 delivers 24.58 TFLOPS, which is 5.3 times the 4.608 TFLOPS of the Intel Arc Graphics 128EU Mobile. The FP16 figures follow the same pattern: the Lisuan Tech part reaches 49.15 TFLOPS (2:1) versus 9.216 TFLOPS (2:1) for the Intel part.

Texture and pixel throughput tell the same story. The Lisuan Tech LX 7G100 achieves 384.0 GTexel/s and 192.0 GPixel/s. The Intel Arc Graphics 128EU Mobile manages 144.0 GTexel/s and 72.00 GPixel/s. The Lisuan Tech card is 2.7 times faster in texture fill rate and 2.7 times faster in pixel fill rate.

Memory bandwidth is where the products diverge most sharply. The Lisuan Tech LX 7G100 has a dedicated 12 GB GDDR6 frame buffer on a 192-bit bus, providing 432.0 GB/s. The Intel Arc Graphics 128EU Mobile relies on system shared memory with bandwidth marked as system dependent. In practice, a dedicated memory subsystem with 432.0 GB/s will sustain high-resolution textures and large datasets far better than any shared-memory configuration, though the exact magnitude depends on the host system's memory implementation.

The shading resources also differ by a factor of six: 6144 shading units on the Lisuan Tech part versus 1024 on the Intel part. Texture mapping units are 192 versus 64, and ROPs are 96 versus 32. These resource ratios are consistent with the throughput deltas observed in the fill rate and compute figures.

The Intel Arc Graphics 128EU Mobile does hold one clear advantage: power efficiency. At 28 W TDP, it draws 8 times less power than the Lisuan Tech LX 7G100's 225 W TDP. This makes the Intel part viable for thin-and-light portable devices, while the Lisuan Tech card requires a desktop chassis with a 550 W suggested PSU and a single 8-pin connector.

Specification Differences

The two products differ in nearly every measurable specification category.

The Intel Arc Graphics 128EU Mobile uses a 10 nm process node from Intel's own foundry, while the Lisuan Tech LX 7G100 uses TSMC's 6 nm node. The Intel part has a base clock of 300 MHz and a boost clock of 2250 MHz.

Architecture Differences

The Intel Arc Graphics 128EU Mobile is built on the Xe-LPG architecture, which is part of the Meteor Lake chip. This is the successor to HD Graphics-M in Intel's product line. The architecture is designed for integration into portable devices, evidenced by the 28 W TDP, the IGP slot width, and the Ring Bus interface. The Xe-LPG architecture supports DirectX 12 (12_1) and Vulkan 1.4, with FP16 compute rated at 2:1 ratio relative to FP32.

The Lisuan Tech LX 7G100 uses the TrueGPU architecture on the 7G106 chip. It is a discrete, dual-slot card with a 225 W TDP and PCIe 4.0 x16 interface. The TrueGPU architecture supports DirectX 12 Ultimate (12_2), which includes features not present in the Intel part's DirectX 12 (12_1) support. The Lisuan Tech card also uses GDDR6 memory with 18 Gbps effective speed, a 192-bit bus, and 432.0 GB/s bandwidth.

Process technology differs: Intel fabricates the Meteor Lake chip on 10 nm, while TSMC fabricates the 7G106 chip on 6 nm. The transistor counts and die sizes are not recorded for either product.

The Intel part has no dedicated memory, relying entirely on system shared memory. The Lisuan Tech card has a full 12 GB GDDR6 frame buffer. This architectural difference dictates the fundamental usage model: the Intel IGP shares bandwidth with the CPU and other system components, while the Lisuan Tech card has dedicated memory bandwidth.

The Intel Arc Graphics 128EU Mobile has a 4.608 TFLOPS FP32 rating and a 9.216 TFLOPS FP16 rating. The Lisuan Tech LX 7G100 has a 24.58 TFLOPS FP32 rating and a 49.15 TFLOPS FP16 rating. Both use a 2:1 FP16 ratio, but the Lisuan Tech part operates at a much higher absolute throughput.

The Lisuan Tech card lists 4x DisplayPort 1.4a outputs, making it suitable for multi-monitor desktop configurations. The Intel part's display outputs are portable device dependent, meaning they vary by the host laptop or handheld hardware.

Both products support OpenGL 4.6. The Intel part supports Vulkan 1.4, which is a newer version than the Lisuan Tech card's Vulkan 1.3. The Lisuan Tech card supports DirectX 12 Ultimate (12_2), which is a higher feature level than the Intel part's DirectX 12 (12_1).

Neither product has recorded benchmark scores, rival comparisons, or percentile data beyond the neutral 50th percentile baseline. The database entries are specification-only at this time, with the Lisuan Tech LX 7G100 having a release date roughly 2.5 years after the Intel Arc Graphics 128EU Mobile.
