AMD Radeon RX 7900M vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The AMD Radeon RX 7900M has three benchmark results in the database, while the Lisuan Tech LX ULTRA has no recorded benchmark scores. Its average benchmark score is listed as 0, and its percentile versus all GPUs sits at 50, which indicates a mid-range placement based on specifications rather than measured performance.

The RX 7900M delivers a 3DMark Steel Nomad DX12 score of 4201. In Geekbench OpenCL, it records 129499 points, and in Geekbench Vulkan, it reaches 158760 points. These results place the AMD part in the 94th percentile among all GPUs in the database. Its average benchmark score across all tests is 97487.

When comparing the RX 7900M to its nearest rivals, the data shows a tight grouping. The AMD Radeon Pro VII averages 97131 points, which is 0.4% higher than the 7900M. The NVIDIA Quadro RTX 6000 averages 101872 points, putting it 4.3% ahead. The AMD Radeon Instinct MI60 averages 92466 points, trailing the 7900M by 5.4%. The NVIDIA RTX A4500 averages 91671 points, sitting 6.3% behind. These deltas indicate that the RX 7900M competes directly with professional workstation cards, sitting in the middle of that pack.

The LX ULTRA has no head-to-head benchmark data and no nearest rivals recorded. Its wins count is zero, as is the RX 7900M's wins count in the head-to-head field. Without benchmark scores for the Lisuan Tech part, the quantitative comparison rests entirely on the AMD card's measured results and the specification sheet of the LX ULTRA.

The absence of benchmark data for the LX ULTRA is significant. The database shows an average benchmark score of 0, which means no tests have been completed or recorded for this GPU. The percentile of 50 reflects a speculative placement, not a measured one. Any direct performance comparison between these two cards must rely on architectural and specification differences rather than benchmark outcomes.

The Verdict

The data supports the AMD Radeon RX 7900M for users who need verified performance. Its 94th percentile ranking, combined with concrete scores in three separate benchmark tests, confirms that it delivers measurable results in DX12, OpenCL, and Vulkan workloads. The nearest rival data shows it performs within 4.3% of the NVIDIA Quadro RTX 6000 and within 0.4% of the AMD Radeon Pro VII, placing it in established professional-grade territory.

The Lisuan Tech LX ULTRA presents a different situation. With no benchmark scores, its 50th percentile is an estimate based on specifications alone. The card lists 24 GB of GDDR6 memory, which exceeds the RX 7900M's 16 GB, and it has 6144 shading units versus 4608 on the AMD card. However, the FP32 compute rate of the LX ULTRA is 24.58 TFLOPS, which is lower than the RX 7900M's 38.52 TFLOPS. The pixel rate of the LX ULTRA is 192.0 GPixel/s, while the RX 7900M manages 401.3 GPixel/s. The texture rate also favors AMD: 601.9 GTexel/s versus 384.0 GTexel/s.

For users who require proven results, the RX 7900M is the only card with recorded data. For users who prioritize memory capacity and are willing to accept unverified specifications, the LX ULTRA offers more VRAM. The data does not support a performance verdict for the LX ULTRA, as no measurements exist.

Architecture Differences

The two GPUs use different architectures and manufacturing processes. The AMD Radeon RX 7900M is built on RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito. It belongs to the Navi Mobile generation within the RX 7000M series. The process node is 5 nm, fabricated by TSMC.

Where Each One Wins

The AMD Radeon RX 7900M wins in every measured performance category. Its FP32 compute of 38.52 TFLOPS is substantially higher than the LX ULTRA's 24.58 TFLOPS. The pixel rate of 401.3 GPixel/s more than doubles the LX ULTRA's 192.0 GPixel/s. The texture rate of 601.9 GTexel/s exceeds the LX ULTRA's 384.0 GTexel/s. Memory bandwidth of 576.0 GB/s outpaces the 432.0 GB/s of the Lisuan Tech card. The AMD part also has a wider 256-bit memory bus, more TMUs and ROPs, and a lower thermal design power of 180 W versus 225 W.

The RX 7900M has verified benchmark results across three tests: 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan. Its 94th percentile ranking places it among the top GPUs in the database. The nearest rival data confirms it competes within a narrow band of professional cards, trailing the Quadro RTX 6000 by only 4.3% and the Radeon Pro VII by 0.4%, while leading the Radeon Instinct MI60 by 5.4% and the RTX A4500 by 6.3%.

The Lisuan Tech LX ULTRA wins in memory capacity with 24 GB versus 16 GB. It also has more shading units at 6144 versus 4608. The card offers a dual-slot form factor with four DisplayPort 1.4a outputs, which is a fixed desktop configuration, whereas the RX 7900M is an integrated package with portable device dependent outputs. The LX ULTRA also has a newer release date of March 16, 2026, compared to October 18, 2023 for the AMD card.

The LX ULTRA has no benchmark data, so its wins are limited to specification advantages. The 24 GB memory capacity is the clearest advantage, useful for workloads that require large datasets in VRAM. The higher shading unit count suggests potential in compute-heavy tasks, but without measured scores, this remains speculative. The FP32 rate of 24.58 TFLOPS, while lower than the RX 7900M, is still a substantial compute figure on its own.

For users with workloads that depend on verified performance, the RX 7900M is the only choice with recorded data. For users who need maximum memory capacity and a discrete desktop card with fixed display outputs, the LX ULTRA offers those features. The data does not indicate any performance scenario where the LX ULTRA is confirmed to outperform the RX 7900M, as no benchmark results exist for the Lisuan Tech part.
