NVIDIA GeForce RTX 5090 Mobile vs Lisuan Tech LX 7G100 Comparison

Where Each One Wins

The recorded data shows a stark asymmetry between these two parts. The NVIDIA GeForce RTX 5090 Mobile has a complete benchmark record across ten tests, while the Lisuan Tech LX 7G100 has no recorded benchmark scores at all. Consequently, the RTX 5090 Mobile wins every measurable comparison by default. Its average benchmark score of 45152 places it at the 84th percentile among all GPUs in the database. The LX 7G100, with an average score of zero, sits at the 50th percentile, which effectively means it has no verified performance footprint yet.

For workloads that stress raw compute and modern graphics APIs, the RTX 5090 Mobile delivers verified results. Its 3DMark Steel Nomad DX12 score of 5871, Geekbench OpenCL score of 201834, and Geekbench Vulkan score of 198405 all represent confirmed performance data. The LX 7G100 has no such numbers, so any use-case classification must rely solely on architectural specifications rather than measured outcomes. The RTX 5090 Mobile is the only part in this comparison with a demonstrated track record in the database.

The LX 7G100, however, brings a different set of physical characteristics that may suit certain installation scenarios. It is a dual-slot card with a 294 mm length, 120 mm height, and 49 mm width, using a PCIe 4.0 x16 interface. The RTX 5090 Mobile is an integrated graphics package (IGP) with no slot width, no power connectors, and display outputs described as portable device dependent. The LX 7G100 offers four DisplayPort 1.4a outputs, which is a concrete connectivity advantage for multi-monitor desktop setups. The RTX 5090 Mobile's display output situation is not specified in the same way.

Architecture Differences

The two GPUs come from unrelated design lineages. The RTX 5090 Mobile uses the GB203 chip built on NVIDIA's Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. The LX 7G100 uses the 7G106 chip under an architecture called TrueGPU, also fabricated by TSMC but on a 6 nm process node. These are fundamentally different silicon designs with no shared heritage.

Transistor counts and die sizes differ dramatically, though the LX 7G100's figures are listed as unknown. The RTX 5090 Mobile integrates 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The LX 7G100 does not disclose these figures, so no direct density comparison is possible.

Memory architecture also diverges sharply. The RTX 5090 Mobile uses 24 GB of GDDR7 across a 256 bit bus, delivering 896.0 GB/s of bandwidth. The LX 7G100 uses 12 GB of GDDR6 across a 192 bit bus, providing 432.0 GB/s. That is a 2x capacity advantage and more than 2x bandwidth advantage for the NVIDIA part. The memory clock differs as well: the RTX 5090 Mobile runs at 1750 MHz (28 Gbps effective), while the LX 7G100 runs at 2250 MHz (18 Gbps effective). The GDDR7 standard on the RTX 5090 Mobile achieves higher effective data rates despite a lower physical clock.

Compute resources tell a similar story. The RTX 5090 Mobile has 10496 shading units, 328 texture mapping units, and 112 raster output units. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. The RTX 5090 Mobile also includes 82 ray tracing cores and 328 tensor cores, while the LX 7G100 lists no ray tracing or tensor core counts at all. This suggests the TrueGPU architecture either lacks these dedicated units or does not expose them in the database.

Clock speeds are only partially recorded. The RTX 5090 Mobile has a base clock of 990 MHz and a boost clock of 1515 MHz. The LX 7G100 has no base or boost clock listed. The RTX 5090 Mobile's pixel rate is 169.7 GPixel/s and its texture rate is 496.9 GTexel/s. The LX 7G100's pixel rate is higher at 192.0 GPixel/s, but its texture rate is lower at 384.0 GTexel/s. Floating point performance also differs: the RTX 5090 Mobile delivers 31.80 TFLOPS in both FP32 and FP16 (1:1 ratio), while the LX 7G100 delivers 24.58 TFLOPS in FP32 but 49.15 TFLOPS in FP16 (2:1 ratio). The LX 7G100 has a clear FP16 advantage, but the RTX 5090 Mobile leads in FP32.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database is empty, meaning no direct paired tests were recorded between these two GPUs. The wins counter shows zero for both parts, reflecting the absence of a formal comparison suite. However, the RTX 5090 Mobile's individual benchmark scores provide a basis for evaluating its standalone performance relative to the broader GPU landscape.

The RTX 5090 Mobile's average score of 45152 positions it within 1% of several known parts. It trails the AMD Radeon Pro 5500 XT by 0.5% (that rival scores 45384), leads the NVIDIA GeForce RTX 4070 Ti by 0.8% (44795), trails the Intel Arc A730M by 1% (45592), and trails the NVIDIA RTX 5880 Ada Generation by 1.8% (45972). These deltas are all within the noise margin of typical benchmark variance, indicating the RTX 5090 Mobile sits in a tightly contested performance band.

Looking at specific tests, the RTX 5090 Mobile shows particular strength in compute workloads. Its Geekbench OpenCL score of 201834 and Vulkan score of 198405 are both robust figures. The PassMark G3D score of 30034 is similarly substantial. The PassMark GPU compute score of 13401 indicates solid general compute capability. DirectX 12 performance in 3DMark Steel Nomad is 5871, which is a modern workload result.

The LX 7G100 has no benchmark scores, so no head-to-head numeric analysis is possible. The data only permits a qualitative statement: the LX 7G100 has not been measured in the database, and therefore cannot be compared on equal footing. Any claims about its performance would be speculative.

The Verdict

The data presents a clear split. For any workload requiring verified performance, the RTX 5090 Mobile is the only option with recorded results. Its 84th percentile standing, average score of 45152, and proximity to parts like the RTX 4070 Ti (0.8% ahead) and RTX 5880 Ada Generation (1.8% behind) place it in a well-understood performance tier. The LX 7G100 has no measurements, so it cannot be recommended on benchmark evidence.

For physical installation and connectivity, the LX 7G100 has concrete advantages. It is a standard dual-slot card with a 294 mm length, four DisplayPort 1.4a outputs, and a PCIe 4.0 x16 interface. The RTX 5090 Mobile is an IGP with no slot footprint and portable device dependent display outputs, which limits its use to laptops or proprietary mobile platforms. The LX 7G100 also delivers higher FP16 throughput at 49.15 TFLOPS versus 31.80 TFLOPS, which could matter for workloads that leverage half-precision arithmetic.

The RTX 5090 Mobile wins on memory capacity (24 GB versus 12 GB), bandwidth (896.0 GB/s versus 432.0 GB/s), FP32 compute (31.80 TFLOPS versus 24.58 TFLOPS), and power efficiency (95 W versus 225 W). It also carries dedicated ray tracing and tensor cores, which the LX 7G100 does not list. The LX 7G100 counters with a higher pixel rate (192.0 GPixel/s versus 169.7 GPixel/s), higher FP16 throughput, and a conventional desktop card form factor.

A builder choosing between these should decide based on platform and workload. The RTX 5090 Mobile suits mobile or compact systems where an IGP is required, and where verified driver and benchmark support matter. The LX 7G100 suits a desktop tower with its dual-slot footprint and standard power connector, but its performance remains unmeasured in the database. Until the LX 7G100 receives recorded benchmark scores, the RTX 5090 Mobile stands as the only part with empirical backing.
