Intel Arc G3 Extreme vs Lisuan Tech LX PRO Comparison

The Intel Arc G3 Extreme and Lisuan Tech LX PRO occupy two very different positions in the graphics hardware landscape. The database records show the Arc G3 Extreme as an integrated graphics solution built for portable devices, while the LX PRO is a large, dual-slot discrete card with dedicated memory. Neither part has recorded benchmark scores, so both sit at the 50th percentile among all GPUs in the database. The average benchmark score for both is zero, meaning no performance measurements have been logged. The primary decision between these two parts rests not on measured speed, but on the fundamental design choices each one makes.

The Verdict

The data indicates that these two products serve entirely different physical and performance roles. The Intel Arc G3 Extreme is an IGP, meaning it is built into a processor package and shares system memory. It consumes 80 W and requires no power connectors. This part is intended for compact, portable systems where space is at a premium and the graphics solution must fit within the thermal and electrical limits of a laptop or handheld device. The Lisuan Tech LX PRO is a dual-slot, 248 mm long card with a 16-pin power connector and a recommended 550 W power supply. It is a desktop component that demands a full expansion slot and dedicated power delivery.

For anyone building a desktop system with room for a large card, the LX PRO is the only sensible choice from this pair. It offers a dedicated 24 GB memory pool, a 192-bit bus, and 432.0 GB/s of bandwidth. The Arc G3 Extreme has no dedicated memory; its bandwidth is system dependent. The LX PRO also delivers substantially higher raw compute figures, with 24.58 TFLOPS of FP32 throughput versus 7.680 TFLOPS for the Arc part.

For portable devices, the Arc G3 Extreme is the only option. Its IGP form factor, 80 W power envelope, and lack of external power connectors make it suitable for integration into a laptop or handheld. The LX PRO cannot be used in such a device due to its slot width, power requirements, and physical dimensions. The recorded data shows no overlapping use cases: one is a mobile integrated part, the other is a desktop discrete card. The choice is dictated by the platform, not by preference.

Architecture Differences

The two chips are built on different process nodes and use different architectures. The Intel Arc G3 Extreme uses a 3 nm process manufactured by Intel, with the Panther Lake chip and Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation. The Lisuan Tech LX PRO uses a 6 nm process from TSMC, with the 7G105 chip and a TrueGPU architecture, part of the 7G100 generation.

The compute layouts differ significantly. The Arc G3 Extreme has 1536 shading units, 48 texture mapping units, and 24 raster output units. It includes 12 ray tracing cores. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs. The LX PRO does not list any ray tracing cores in the database. The Arc part has no listed tensor cores, and neither does the LX PRO.

Memory architecture is a major divergence. The Arc G3 Extreme uses system shared memory, with the type, bus width, and bandwidth all marked as system dependent. Memory clocks are also system shared. The LX PRO has 24 GB of GDDR6 memory on a 192-bit bus, with memory clocks at 2250 MHz and 18 Gbps effective. Its bandwidth is a fixed 432.0 GB/s. This means the LX PRO has a deterministic memory subsystem, while the Arc part's performance will vary with the host system's memory configuration.

The API support is similar but not identical. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Arc G3 Extreme supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. The Arc part is newer in this regard, with a higher Vulkan version. The LX PRO has four DisplayPort 1.4a outputs, while the Arc G3 Extreme has display outputs that are portable device dependent.

The release dates differ by a few months. The LX PRO was released on March 16, 2026, and the Arc G3 Extreme on May 31, 2026. Both are marked as active production status.

Head-to-Head Benchmarks

The database contains no recorded benchmark entries for either GPU, and the head-to-head benchmark array is empty. The wins counter shows zero for both parts. As such, there are no measured performance comparisons to walk through. The analysis must rely on the theoretical specifications that are recorded.

The raw throughput figures favor the LX PRO by a wide margin. The LX PRO delivers 24.58 TFLOPS of FP32 performance, which is 3.2 times the 7.680 TFLOPS of the Arc G3 Extreme. The FP16 figures follow the same ratio: 49.15 TFLOPS versus 15.36 TFLOPS, with both listed at a 2:1 ratio relative to FP32.

Pixel and texture rates also favor the LX PRO. The LX PRO has a pixel rate of 192.0 GPixel/s and a texture rate of 384.0 GTexel/s. The Arc G3 Extreme has a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. The LX PRO is 3.2 times faster in both metrics, matching the shading unit ratio of 6144 versus 1536.

The memory bandwidth gap is even larger. The LX PRO has 432.0 GB/s of dedicated bandwidth. The Arc G3 Extreme has system dependent bandwidth, which could range anywhere from low-speed shared memory to higher-speed LPDDR or similar, but the exact figure is not recorded. The LX PRO's fixed 432.0 GB/s is a guaranteed figure, while the Arc part's effective bandwidth cannot be stated.

The power draw favors the Arc G3 Extreme. The Arc part uses 80 W, while the LX PRO uses 225 W. The Arc part has no power connectors, while the LX PRO requires a single 16-pin connector and a suggested 550 W power supply. The Arc part is an IGP, so its power is drawn through the processor socket rather than a dedicated graphics power input.

Where Each One Wins

The Intel Arc G3 Extreme wins in power efficiency and portability. Its 80 W power draw is less than a third of the LX PRO's 225 W. It requires no power connectors, making it suitable for systems without discrete graphics power cabling. The IGP slot width means it takes up no expansion slot space. Its Vulkan 1.4 support is a version ahead of the LX PRO's 1.3. The 3 nm process node from Intel is smaller than the 6 nm node used by TSMC for the LX PRO, which may contribute to the lower power envelope. The Arc part also has 12 ray tracing cores, a feature that the LX PRO does not list in the database.

The Lisuan Tech LX PRO wins in raw compute and memory capacity. Its 6144 shading units, 192 TMUs, and 96 ROPs provide the structural basis for its higher throughput. The 24.58 TFLOPS FP32 figure is more than triple the Arc part's 7.680 TFLOPS. The 24 GB GDDR6 memory pool with 432.0 GB/s bandwidth is a substantial advantage over the Arc part's system shared memory. The LX PRO has a fixed memory clock of 2250 MHz with 18 Gbps effective speed, giving it deterministic memory performance. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate are both 3.2 times higher than the Arc part's figures.

The LX PRO also wins on display connectivity for desktop use. It has four DisplayPort 1.4a outputs, while the Arc G3 Extreme's display outputs are portable device dependent, meaning they are not standardized for external monitors. The LX PRO's PCIe 4.0 x16 bus interface provides a dedicated high-bandwidth connection to the host, whereas the Arc part uses an IGP bus interface.
