Intel Arc G3 Extreme vs Lisuan Tech LX ULTRA Comparison

The Verdict

The data shows two fundamentally different graphics solutions with no benchmark overlap, making a direct performance comparison impossible from recorded measurements. The Intel Arc G3 Extreme is an integrated GPU (IGP) designed for portable devices, drawing 80 W and sharing system memory. The Lisuan Tech LX ULTRA is a dual-slot, 225 W add-in board with 24 GB of dedicated GDDR6 memory and a 192-bit bus. Benchmark results indicate these products target distinct segments: the Arc G3 Extreme fits thin-and-light systems where space and power are constrained, while the LX ULTRA serves desktop builds requiring discrete graphics performance.

For users constrained to integrated graphics, the Arc G3 Extreme delivers modern API support including DirectX 12 Ultimate and Vulkan 1.4 within a 3 nm process node. For desktop users needing dedicated memory and higher raw throughput, the LX ULTRA provides 24.58 TFLOPS FP32 compute, 192.0 GPixel/s pixel rate, and 384.0 GTexel/s texture rate, all figures that dwarf the Arc G3 Extreme's 7.680 TFLOPS, 60.00 GPixel/s, and 120.0 GTexel/s. The verdict from the data is clear: the LX ULTRA is the performance-oriented choice, while the Arc G3 Extreme is the efficiency-oriented integrated solution.

Neither product has recorded benchmark scores or nearest rival comparisons in the database, so both sit at the 50th percentile among all GPUs by default. The absence of benchmark data means no aggregate performance ranking can be assigned. The choice between these two hinges entirely on system form factor and memory requirements, not measured performance.

Where Each One Wins

The Intel Arc G3 Extreme wins in integration and efficiency. Its 80 W TDP, IGP slot width, no power connectors, and bus interface of IGP make it suitable for portable devices where discrete graphics cannot be installed. The 3 nm process node from Intel foundry indicates a modern manufacturing approach. Its base clock of 300 MHz and boost clock of 2500 MHz show a wide dynamic range, allowing low idle power and higher performance when needed. The display outputs are listed as portable device dependent, confirming its role in laptops and compact systems.

The Lisuan Tech LX ULTRA wins in dedicated resources and throughput. Its 24 GB GDDR6 memory at 432.0 GB/s bandwidth eliminates reliance on system memory. The 6144 shading units, 192 texture mapping units, and 96 render output units provide substantial parallel processing capacity. The 225 W TDP with a 550 W suggested PSU and 1x 16-pin power connector indicates a high-power discrete design. The PCIe 4.0 x16 bus interface offers dedicated bandwidth to the host system. Display outputs include 4x DisplayPort 1.4a, supporting multi-monitor desktop configurations.

The FP32 throughput difference is decisive: the LX ULTRA delivers 24.58 TFLOPS versus the Arc G3 Extreme's 7.680 TFLOPS, a 3.2x advantage. The pixel rate of 192.0 GPixel/s versus 60.00 GPixel/s gives the LX ULTRA a 3.2x lead in fill-rate-bound workloads. The texture rate of 384.0 GTexel/s versus 120.0 GTexel/s likewise shows a 3.2x advantage. These ratios hold consistently across compute, pixel, and texture metrics.

Architecture Differences

The Arc G3 Extreme uses the Xe3-LPG architecture on Intel's Panther Lake chip, part of the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel's foundry. The architecture includes 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The FP16 rate of 15.36 TFLOPS achieves a 2:1 ratio to FP32, indicating unified shader execution. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Lisuan Tech LX ULTRA uses the TrueGPU architecture on the 7G105 chip, part of the 7G100 generation. It is fabricated on a 6 nm process at TSMC. The architecture includes 6144 shading units, 192 TMUs, and 96 ROPs. No ray tracing cores are listed. The FP16 rate of 49.15 TFLOPS also achieves a 2:1 ratio to FP32. API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

The process node difference is notable: 3 nm versus 6 nm. Intel's newer node allows the Arc G3 Extreme to operate at 80 W despite lower clock speeds, while the LX ULTRA uses a more mature TSMC node at 225 W. The memory architecture differs completely: the Arc G3 Extreme uses system shared memory with system dependent bandwidth, while the LX ULTRA has dedicated 24 GB GDDR6 at 2250 MHz with 18 Gbps effective speed, 192-bit bus, and 432.0 GB/s bandwidth.

The ray tracing capability exists on the Arc G3 Extreme with 12 dedicated RT cores, while the LX ULTRA lists no RT cores. This suggests the Arc G3 Extreme may handle ray-traced workloads through dedicated hardware, while the LX ULTRA either lacks this feature or implements it differently. The Vulkan version also differs: 1.4 on the Arc G3 Extreme versus 1.3 on the LX ULTRA.
