Intel Arc G3 vs Lisuan Tech LX ULTRA Comparison

The Verdict

The recorded data places the Intel Arc G3 and Lisuan Tech LX ULTRA in fundamentally different product categories. The Arc G3 is an integrated graphics processor (IGP) built for a mobile platform, while the LX ULTRA is a dual-slot discrete add-in board. Their performance percentiles are identical at 50 against all GPUs, but that parity masks the architectural gulf between them. The Arc G3 delivers 6.144 TFLOPS FP32 with a 25 W TDP, while the LX ULTRA delivers 24.58 TFLOPS FP32 at 225 W. The LX ULTRA offers roughly four times the raw FP32 throughput, four times the pixel rate, and four times the texture rate. For any workload that scales with shading units, texture units, or memory bandwidth, the LX ULTRA is the clear choice from the data. For a system constrained to integrated graphics with no power connectors and a portable device display output, the Arc G3 is the only viable option. The LX ULTRA requires a 550 W suggested PSU and a 16-pin power connector, so it cannot serve as a drop-in replacement for an IGP. The data shows two products aimed at separate use cases: a low-power integrated solution versus a high-throughput discrete GPU.

Architecture Differences

The two GPUs diverge at every architectural layer. The Intel Arc G3 uses a 3 nm process node fabricated by Intel, based on the Panther Lake chip with the Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation. The Lisuan Tech LX ULTRA uses a 6 nm process node fabricated by TSMC, based on the 7G105 chip with the TrueGPU architecture, part of the 7G100 generation. The process node difference alone suggests a significant gap in transistor density and power efficiency, though the exact transistor counts and die sizes are not recorded for either part.

The shading engine counts differ sharply. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. The LX ULTRA has 6144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing core count listed. The LX ULTRA therefore has 4.8 times the shading units, 4.8 times the TMUs, and 4.8 times the ROPs of the Arc G3. The LX ULTRA also carries dedicated GDDR6 memory, while the Arc G3 shares system memory. The Arc G3's memory clock is listed as system shared, and its bandwidth is system dependent. The LX ULTRA uses 24 GB of GDDR6 on a 192 bit bus at 2250 MHz, yielding 432.0 GB/s of bandwidth. This dedicated memory arrangement is a structural advantage for the LX ULTRA in bandwidth-bound scenarios.

The LX ULTRA has no listed ray tracing cores, while the Arc G3 has 10. Both parts support DirectX 12 Ultimate (12_2), so the API feature set is nominally equal at the DirectX level. Both support OpenGL 4.6. Vulkan support differs slightly: the Arc G3 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The LX ULTRA uses a PCIe 4.0 x16 bus interface, while the Arc G3 is an IGP with no separate bus interface. The LX ULTRA provides four DisplayPort 1.4a outputs, whereas the Arc G3's display outputs are portable device dependent, meaning they are tied to the host system.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for this pair, and the wins counters are zero for both. The comparison therefore rests on the recorded throughput and memory specifications. The FP32 throughput difference is the largest single gap. The LX ULTRA delivers 24.58 TFLOPS against the Arc G3's 6.144 TFLOPS, which is exactly four times the raw compute. In FP16, the LX ULTRA delivers 49.15 TFLOPS against the Arc G3's 12.29 TFLOPS, also a factor of four. Both parts use a 2:1 FP16 ratio, so the relative gap is consistent across precisions.

Pixel throughput follows the same pattern. The LX ULTRA posts 192.0 GPixel/s against 48.00 GPixel/s for the Arc G3, again a factor of four. Texture throughput is 384.0 GTexel/s for the LX ULTRA versus 96.00 GTexel/s for the Arc G3. These ratios align with the shading unit counts, confirming that the LX ULTRA scales its fixed-function units in lockstep with its shader array.

Memory bandwidth is where the gap becomes most extreme. The Arc G3's bandwidth is system dependent, so no fixed figure is recorded. The LX ULTRA has 432.0 GB/s of dedicated GDDR6 bandwidth. In practice, an IGP sharing system memory will be limited by the host memory controller and the shared bus, so the effective bandwidth available to the Arc G3 is likely far lower than the LX ULTRA's dedicated figure. For workloads that stream large textures or geometry, the LX ULTRA's 24 GB GDDR6 pool and 192 bit bus provide a structural advantage that the Arc G3 cannot match.

Clock behavior differs as well. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The LX ULTRA has no base or boost clock recorded, only a memory clock of 2250 MHz with 18 Gbps effective data rate. The Arc G3's boost clock is high for an integrated part, but its shading unit count is low. The LX ULTRA compensates with far more units even without a recorded clock. The power envelope reflects this: the Arc G3 consumes 25 W, while the LX ULTRA consumes 225 W, a ninefold difference. That power budget buys the LX ULTRA the compute and memory advantages described above.

Specification Differences

The specification table shows clear separation between the two parts. The Arc G3 has a 3 nm Intel process, while the LX ULTRA uses 6 nm TSMC. The Arc G3 is an IGP with a 25 W TDP and no power connectors; the LX ULTRA is a dual-slot card with a 225 W TDP and a single 16-pin power connector. The LX ULTRA lists a suggested PSU of 550 W, while the Arc G3 has no suggested PSU. The bus interface differs: IGP versus PCIe 4.0 x16.

Memory specifications are entirely different. The Arc G3 uses system shared memory with system dependent bandwidth. The LX ULTRA has 24 GB of GDDR6, a 192 bit bus, 432.0 GB/s bandwidth, and a 2250 MHz memory clock. The shader arrays differ by a factor of 4.8: 1280 shading units for the Arc G3 versus 6144 for the LX ULTRA, with matching ratios for TMUs and ROPs. The Arc G3 has 10 ray tracing cores; the LX ULTRA has none listed. The Arc G3 reaches a 2400 MHz boost clock; the LX ULTRA has no clock recorded. Pixel rate is 48.00 GPixel/s versus 192.0 GPixel/s, and texture rate is 96.00 GTexel/s versus 384.0 GTexel/s.

The physical form factors differ completely. The Arc G3 has no recorded dimensions and is an IGP, so it occupies no expansion slot. The LX ULTRA measures 268 mm long, 112 mm tall, and 40 mm wide. Its slot width is dual-slot. Display outputs are portable device dependent for the Arc G3, while the LX ULTRA offers 4x DisplayPort 1.4a. Release dates are close: the LX ULTRA came out on 2026-03-16, while the Arc G3 followed on 2026-05-31. Both are listed as active in production. Neither part has a recorded launch MSRP. Both have an equal percentile of 50 against all GPUs and an average benchmark score of zero, which reflects the absence of benchmark entries in the database rather than measured performance.
