Intel Arc G3 vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The Intel Arc G3 and Lisuan Tech LX MAX occupy completely different positions in the database. The Arc G3 is an integrated graphics processor built into the Panther Lake chip, designed for portable devices where space and power are constrained. The LX MAX is a discrete, dual-slot expansion card with its own dedicated memory subsystem, aimed at systems that can accommodate a full-length 248 mm card.

Based on the recorded specifications, the LX MAX wins decisively in raw compute throughput. Its shading unit count of 6144 is nearly five times the Arc G3's 1280. The texture mapping units tell a similar story: 192 versus 40. Raster operations units stand at 96 versus 20. These are not marginal differences; they represent a completely different performance class.

The Arc G3 wins in the integration category. It requires no power connectors, occupies no expansion slot, and draws only 25 W. The LX MAX needs a 1x 16-pin connector, a 550 W suggested power supply, and a dual-slot footprint. For systems where physical space and thermal envelope are the primary constraints, the Arc G3 is the only viable option between these two.

The memory situation further separates them. The LX MAX carries 12 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The Arc G3 relies on system shared memory with bandwidth that is system dependent. This means the LX MAX has predictable, dedicated memory performance, while the Arc G3's memory behavior varies entirely with the host system's configuration.

Architecture Differences

The two GPUs come from different foundries and process nodes. The Intel Arc G3 uses a 3 nm process at Intel's own fabs, built on the Xe3-LPG architecture. The Lisuan Tech LX MAX uses TSMC's 6 nm process with a "TrueGPU" architecture. This process node difference is significant: the 3 nm node is substantially more advanced, which helps explain how the Arc G3 achieves meaningful performance within a 25 W envelope.

Clock behavior diverges sharply. The Arc G3 has explicit clock specifications: a 300 MHz base and 2400 MHz boost. The LX MAX has no base or boost clock listed in the database. Instead, its memory clock is specified at 2250 MHz with 18 Gbps effective data rate. The compute clocks for the LX MAX remain unspecified, so direct clock-to-clock comparison is not possible from the recorded data.

The API support shows subtle differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Arc G3 supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. This means the Intel part has a newer Vulkan revision, potentially offering additional features or optimizations for applications that target the newer specification.

Ray tracing hardware differs as well. The Arc G3 includes 10 dedicated ray tracing cores. The LX MAX lists no ray tracing core count in the database. This does not necessarily mean the LX MAX lacks ray tracing capability, but the database does not record dedicated RT hardware for it.

The bus interface separates them fundamentally. The Arc G3 is an IGP, integrated directly into the processor package. The LX MAX uses PCIe 4.0 x16, a full-bandwidth external connection. Display outputs also differ: the Arc G3's outputs are portable device dependent, while the LX MAX provides 4x DisplayPort 1.4a connectors.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between these two GPUs. Both have an average benchmark score of 0 and both sit at the 50th percentile versus all GPUs. With zero wins recorded for either side, the quantitative comparison must rely entirely on the specification data.

The FP32 compute figures provide the clearest measurable gap. The LX MAX delivers 24.58 TFLOPS of single-precision floating point performance. The Arc G3 delivers 6.144 TFLOPS. This puts the LX MAX at exactly four times the FP32 throughput of the Arc G3. In FP16, the LX MAX reaches 49.15 TFLOPS versus the Arc G3's 12.29 TFLOPS, again a 4:1 ratio.

Pixel and texture rates follow the same pattern. The LX MAX achieves 192.0 GPixel/s and 384.0 GTexel/s. The Arc G3 achieves 48.00 GPixel/s and 96.00 GTexel/s. Both ratios are exactly 4:1. This consistency suggests the architecture scaling between the two is uniform across these metrics.

The memory bandwidth gap is even larger. The LX MAX's 432.0 GB/s dedicated bandwidth dwarfs the system-dependent bandwidth of the Arc G3. Since the Arc G3's memory performance cannot be quantified without knowing the host system's memory configuration, the practical difference could range from modest to extreme depending on the platform.

The TDP figures frame the efficiency story. The LX MAX consumes 225 W, which is exactly nine times the Arc G3's 25 W. Yet the LX MAX delivers only four times the compute throughput. This means the Arc G3 is significantly more efficient in terms of performance per watt, assuming the specifications translate directly to real-world performance.

The Verdict

The data presents a straightforward choice based on system requirements. The Lisuan Tech LX MAX is the clear performance leader across every measurable compute metric in the database. Its 24.58 TFLOPS FP32 throughput, 432.0 GB/s memory bandwidth, and 192.0 GPixel/s pixel rate place it in an entirely different performance tier than the Arc G3. Systems that need maximum graphics throughput and have the physical space, power delivery, and cooling to support a 225 W dual-slot card should select the LX MAX.

The Intel Arc G3 serves a different purpose entirely. Its 25 W TDP, lack of power connectors, and IGP form factor make it suitable for portable devices where the LX MAX physically cannot fit. The 3 nm process node and Vulkan 1.4 support indicate a modern, efficient design. The 10 ray tracing cores provide hardware acceleration that the LX MAX does not list. For integrated graphics applications, the Arc G3 is the only option between these two.

The release dates show the LX MAX launched on 2026-03-16, while the Arc G3 followed on 2026-05-31. Both are currently listed as active production parts. The database records no benchmark scores or nearest rivals for either GPU, so the percentile ranking of 50 for both reflects the absence of measured data rather than actual performance positioning.

The efficiency comparison is instructive. The LX MAX consumes nine times the power of the Arc G3 but delivers only four times the compute throughput. This indicates the Arc G3 has superior performance per watt, a critical factor for battery-powered portable devices. The LX MAX trades efficiency for absolute performance, which is appropriate for desktop systems with ample power budgets.

The memory architecture difference carries practical implications. The LX MAX's dedicated 12 GB GDDR6 pool ensures consistent performance regardless of system configuration. The Arc G3's system shared memory means its effective bandwidth depends entirely on the host platform's memory subsystem, introducing variability that cannot be quantified from the database alone.

In summary, the recorded data supports a clear bifurcation: the Lisuan Tech LX MAX for maximum compute and memory performance in desktop systems, and the Intel Arc G3 for integrated, low-power applications where the LX MAX's physical and electrical requirements cannot be met.
