AMD Radeon RX 6600 LE vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast in benchmark coverage between the AMD Radeon RX 6600 LE and the Lisuan Tech LX ULTRA. The RX 6600 LE has two recorded benchmark scores: 69,229 in Geekbench OpenCL and 72,428 in Geekbench Vulkan. Its average benchmark score across all tests is 70,829. The LX ULTRA, by contrast, has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and its percentile ranking among all GPUs sits at 50. The RX 6600 LE, meanwhile, holds a 91st percentile ranking.

The absence of benchmark data for the LX ULTRA prevents any direct head-to-head numerical comparison. The database instead places the RX 6600 LE against a set of nearest rivals. These comparisons show the RX 6600 LE delivering a 1.0% higher average score than the NVIDIA RTX A3000 Mobile (70,140), a 1.2% higher average score than the NVIDIA Quadro P6000 (69,986), and a 1.4% higher average score than the AMD Radeon Pro WX 8200 (69,870). Against the AMD Radeon RX 6650M, the RX 6600 LE trails by 1.3%, as the 6650M posts an average score of 71,768.

The LX ULTRA has no nearest rivals listed, no wins recorded, and no benchmark scores. This means the database cannot compute a win count for either card in a head-to-head sense. What the data does show is that the RX 6600 LE is a measured, verified performer with a clear performance envelope, while the LX ULTRA remains uncharacterized by benchmark results.

Where Each One Wins

The benchmark data gives a clear advantage to the RX 6600 LE in terms of verifiable performance. It has recorded scores, a 91st percentile ranking, and a set of nearest rivals that bracket its performance within a narrow 1.4% range. The RX 6600 LE edges out the NVIDIA RTX A3000 Mobile, the NVIDIA Quadro P6000, and the AMD Radeon Pro WX 8200 in average score, while trailing the AMD Radeon RX 6650M by a small margin. This places the RX 6600 LE in a well-understood performance tier.

The LX ULTRA wins on paper specifications. It offers triple the memory capacity (24 GB versus 8 GB), a wider memory bus (192 bit versus 128 bit), and nearly double the memory bandwidth (432.0 GB/s versus 224.0 GB/s). Its shading unit count is more than triple that of the RX 6600 LE (6,144 versus 1,792), and its FP32 compute throughput is 24.58 TFLOPS versus 8.942 TFLOPS. The LX ULTRA also has higher texture rate, pixel rate, and a larger PCIe bus interface (x16 versus x8).

The LX ULTRA's architecture uses a smaller 6 nm process node compared to the 7 nm node of the RX 6600 LE. It also supports a newer memory clock speed of 2250 MHz with 18 Gbps effective speed, versus 1750 MHz with 14 Gbps effective speed for the RX 6600 LE.

The RX 6600 LE wins on established, measured results. Its 91st percentile ranking indicates strong standing among all GPUs in the database. The LX ULTRA's 50th percentile ranking with no benchmark scores reflects an unverified status.

The RX 6600 LE also offers a broader set of display outputs, including an HDMI 2.1 port alongside three DisplayPort 1.4a outputs. The LX ULTRA provides four DisplayPort 1.4a outputs only.

The power profiles favor the RX 6600 LE for systems with modest power supply requirements. Its 132 W TDP and 300 W suggested PSU are substantially lower than the LX ULTRA's 225 W TDP and 550 W suggested PSU.

Physical footprint favors the RX 6600 LE, which is shorter at 190 mm versus 268 mm for the LX ULTRA. Both cards share the same 40 mm width and dual-slot design.

The database records the RX 6600 LE as having a predecessor (Navi) and a successor (Navi III), indicating a defined product lineage. The LX ULTRA has no recorded predecessor or successor.

In practical terms, the RX 6600 LE is the only one of the two with a measured performance profile. The LX ULTRA's specifications suggest higher theoretical throughput, but the absence of benchmark results means the database cannot confirm real-world performance. The RX 6600 LE's nearest rival comparisons show it performing within 1.3% of the AMD Radeon RX 6650M, which gives a concrete reference point for its capabilities. The LX ULTRA has no such reference points in the database.
