AMD Radeon RX 7900M vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The recorded data splits these two GPUs into entirely different performance categories. The AMD Radeon RX 7900M sits at the 94th percentile among all GPUs in the database, with an average benchmark score of 97,487. The Lisuan Tech LX MAX shows a 50th percentile placement and an average benchmark score of zero, meaning no benchmark results have been recorded for it in the database. This is not a close contest by any measurable standard.

The RX 7900M delivers three concrete benchmark results. In 3DMark Steel Nomad DX12, it scores 4,201. In Geekbench OpenCL, it scores 129,499. In Geekbench Vulkan, it scores 158,760. These figures establish a clear baseline of real-world testable performance. The LX MAX has no entries in the benchmark database, so there are no wins to attribute to it. Every available performance metric belongs to the AMD part.

For users focused on compute workloads, the RX 7900M shows strength in both OpenCL and Vulkan APIs. The Vulkan score of 158,760 exceeds the OpenCL score of 129,499 by roughly 22.6 percent, indicating that the architecture responds well to Vulkan's lower-level command and memory management model. The OpenCL result still represents a substantial compute capability, placing the card near workstation-class competitors. The 3DMark Steel Nomad score of 4,201 provides a DirectX 12 gaming-oriented data point, showing the card can handle modern DX12 titles with heavy geometry and ray tracing workloads.

The LX MAX cannot be assigned any wins based on benchmark data because none exists. Its specification sheet lists capabilities, but without measured results, the database cannot confirm how those specifications translate into actual performance. The 50th percentile placement appears to be a default or estimated value rather than a derived one, given the zero average score.

Architecture Differences

The two GPUs come from completely different design philosophies. The AMD Radeon RX 7900M uses the Navi 31 chip built on RDNA 3.0 architecture, codenamed Plum Bonito. It belongs to the Navi Mobile generation within the RX 7000 series and is manufactured on a 5 nm process at TSMC. The die contains 57,700 million transistors across a 529 mm² area, yielding a transistor density of 109.1 million per square millimeter. The Lisuan Tech LX MAX uses the 7G106 chip based on TrueGPU architecture, part of the 7G100 generation. It uses a 6 nm TSMC process, but the database lists transistor count and die size as unknown.

The RX 7900M carries 4,608 shading units, 288 texture mapping units, and 192 raster operation units. It includes 72 ray tracing cores dedicated to hardware-accelerated ray tracing. The LX MAX lists 6,144 shading units, 192 TMUs, and 96 ROPs. It has no ray tracing core count recorded. The shading unit advantage for the LX MAX is significant on paper, but the RX 7900M counters with higher texture and pixel throughput. The RX 7900M achieves a pixel rate of 401.3 GPixel/s and a texture rate of 601.9 GTexel/s. The LX MAX produces 192.0 GPixel/s and 384.0 GTexel/s. The AMD card delivers over twice the pixel fill rate and roughly 56.7 percent higher texture fill rate.

Compute throughput follows the same pattern. The RX 7900M reaches 38.52 TFLOPS FP32 and 77.05 TFLOPS FP16 with a 2:1 ratio. The LX MAX reaches 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16. The AMD part leads by approximately 56.7 percent in both FP32 and FP16 compute. Clock speeds differ as well, though the LX MAX has no base or boost clock listed. The RX 7900M runs at 1,825 MHz base and 2,090 MHz boost, with memory clocked at 2,250 MHz or 18 Gbps effective.

Memory configurations diverge sharply. The RX 7900M uses 16 GB of GDDR6 on a 256-bit bus, producing 576.0 GB/s of bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The AMD card offers 33.3 percent more memory capacity and 33.3 percent more bandwidth. Both use PCIe 4.0 x16 interfaces. The RX 7900M lists no power connector and an IGP slot width, while the LX MAX uses a dual-slot design with a single 16-pin power connector and a suggested 550 W PSU. The TDP figures also differ: 180 W for the AMD card versus 225 W for the LX MAX.

API support shows near parity. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan, though the RX 7900M lists Vulkan 1.4 while the LX MAX lists Vulkan 1.3. The RX 7900M has display outputs described as portable device dependent, whereas the LX MAX provides four DisplayPort 1.4a outputs.

The Verdict

The database contains no benchmark results for the Lisuan Tech LX MAX. Every performance figure associated with the AMD Radeon RX 7900M comes from actual recorded measurements. Users seeking verified performance data should select the RX 7900M, as it is the only card in this comparison with demonstrable results.

The RX 7900M compares favorably against established workstation GPUs. It sits 0.4 percent above the AMD Radeon Pro VII, 5.4 percent above the AMD Radeon Instinct MI60, and 6.3 percent above the NVIDIA RTX A4500. It trails the NVIDIA Quadro RTX 6000 by 4.3 percent. These deltas place the RX 7900M in the upper tier of professional-grade accelerators despite being a mobile-oriented part.

The LX MAX, by contrast, offers no comparable data. Its 50th percentile placement suggests mid-range positioning, but without benchmark scores, that placement cannot be validated. Its specification sheet shows a higher shading unit count and a lower TDP-normalized performance profile, but specifications alone do not constitute measured performance.

For buyers who require ray tracing, the RX 7900M has 72 dedicated RT cores. The LX MAX has no RT core count in the database. For memory-intensive workloads, the RX 7900M provides 16 GB versus 12 GB, with a wider 256-bit bus. The LX MAX does offer a dual-slot form factor with four DisplayPort outputs, which may suit desktop integration, but that does not offset the absence of performance data.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database contains no entries, so there are no direct side-by-side test results. The comparison must instead rely on the individual benchmark scores recorded for the RX 7900M and the complete absence of scores for the LX MAX.

The RX 7900M's strongest recorded result is its Geekbench Vulkan score of 158,760. This represents a compute workload that stresses asynchronous compute, graphics queues, and memory bandwidth. The OpenCL score of 129,499 covers a different execution path, often used for general-purpose GPU compute in scientific and professional applications. The difference between these two scores, roughly 29,261 points, indicates that the RDNA 3.0 architecture extracts more performance from Vulkan's explicit control model than from OpenCL's more abstracted model.

The 3DMark Steel Nomad DX12 score of 4,201 provides the only gaming-oriented data point. Steel Nomad emphasizes DirectX 12 feature utilization, including mesh shaders and variable rate shading. A score in this range places the RX 7900M above typical mid-range mobile GPUs and into enthusiast territory, consistent with its 94th percentile ranking.

Against its nearest rivals, the RX 7900M's 97,487 average score positions it within a narrow performance band. The AMD Radeon Pro VII scores 97,131, just 356 points lower. The NVIDIA Quadro RTX 6000 scores 101,872, which is 4,385 points higher. The AMD Radeon Instinct MI60 scores 92,466, which is 5,021 points lower. The NVIDIA RTX A4500 scores 91,671, which is 5,816 points lower. The RX 7900M thus clusters with the Pro VII and Quadro RTX 6000 while clearly outpacing the Instinct MI60 and RTX A4500.

For the LX MAX, the database shows zero benchmark scores, zero wins in head-to-head comparisons, and no nearest rivals. The specification sheet lists 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16, which fall below the RX 7900M's 38.52 and 77.05 TFLOPS respectively. The LX MAX also trails in pixel rate (192.0 versus 401.3 GPixel/s), texture rate (384.0 versus 601.9 GTexel/s), memory capacity (12 GB versus 16 GB), and memory bandwidth (432.0 versus 576.0 GB/s). It leads only in shading unit count and TDP, neither of which constitutes a performance win.

The absence of any measured results for the LX MAX means the benchmark comparison defaults entirely to the RX 7900M. Users examining this page for performance data will find the AMD part fully characterized and the Lisuan Tech part unverified. The recorded data supports the RX 7900M as the only testable option in this pairing.
