Architecture Differences

The RTX 5090 Mobile uses the GB203 chip built on a 5 nm process at TSMC, with 45,600 million transistors on a 378 mm² die. This yields a transistor density of 120.6 million per square millimeter. The architecture is Blackwell 2.0, part of the GeForce 50 Mobile generation. The LX MAX uses the 7G106 chip on a 6 nm process, also from TSMC, but the transistor count and die size are recorded as unknown, and no transistor density is listed. Its architecture is TrueGPU from the 7G100 generation.

The RTX 5090 Mobile has 10,496 shading units, 328 TMUs, and 112 ROPs. It also includes 82 RT cores and 328 tensor cores. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs, but no RT cores or tensor cores are recorded. This indicates a fundamental difference in feature support: the RTX 5090 Mobile carries dedicated hardware for ray tracing and tensor operations, while the LX MAX data does not list such components.

Clock behavior differs as well. The RTX 5090 Mobile has a base clock of 990 MHz and a boost clock of 1515 MHz. The LX MAX has no base or boost clock values in the database. Memory clocks are recorded for both: the RTX 5090 Mobile runs at 1750 MHz with 28 Gbps effective, while the LX MAX runs at 2250 MHz with 18 Gbps effective.

The FP16 performance shows a notable architectural divergence. The RTX 5090 Mobile achieves 31.80 TFLOPS FP16 with a 1:1 ratio to FP32, meaning there is no dedicated half-precision acceleration. The LX MAX achieves 49.15 TFLOPS FP16 with a 2:1 ratio, indicating that its FP16 throughput is double its FP32 rate. This suggests the LX MAX is optimized for workloads that benefit from half-precision computation, while the RTX 5090 Mobile treats FP16 and FP32 equally.

The API support also differs. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5090 Mobile supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. The RTX 5090 Mobile uses a PCIe 5.0 x16 bus interface, while the LX MAX uses PCIe 4.0 x16.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The RTX 5090 Mobile has ten individual benchmark scores, while the LX MAX has none. This absence of direct comparison data means that any performance analysis must rely on the RTX 5090 Mobile’s recorded results and its position relative to other GPUs in the database.

The RTX 5090 Mobile’s strongest recorded score is in Geekbench OpenCL at 201834, followed by Geekbench Vulkan at 198405. In 3DMark Steel Nomad DX12, it scores 5871. The Passmark suite shows a G3D score of 30034 and a GPU compute score of 13401. The older DirectX tests show lower figures: Passmark DirectX 10 at 183, DirectX 11 at 269, DirectX 12 at 138, and DirectX 9 at 324. The G2D score is 1057.

The LX MAX has no recorded scores in any test. The database lists its average benchmark score as 0 and its percentile as 50, but this percentile appears to be a default value rather than a measured result, since there are no underlying benchmarks. The RTX 5090 Mobile’s percentile is 84, indicating that it outperforms most GPUs in the database. Its nearest rivals bracket its average score within a narrow range: the Intel Arc A730M is 1% higher, the AMD Radeon Pro 5500 XT is 0.5% higher, the NVIDIA GeForce RTX 4070 Ti is 0.8% lower, and the NVIDIA RTX 5880 Ada Generation is 1.8% higher. This clustering suggests that the RTX 5090 Mobile’s average performance is well established and consistent with mid-to-high-end desktop GPUs from previous generations.

The Verdict

The data presents a clear split. The RTX 5090 Mobile has extensive benchmark coverage, with an average score of 45152 and a percentile of 84. The LX MAX has no benchmark scores at all, making its measured performance unknown. For any workload that relies on recorded performance data, the RTX 5090 Mobile is the only option with evidence of capability.

The RTX 5090 Mobile also leads in raw compute specifications. It has more shading units, more TMUs, more ROPs, higher FP32 throughput, higher texture rate, more memory capacity, and more memory bandwidth. Its 24 GB GDDR7 configuration with 896.0 GB/s bandwidth is a substantial advantage over the LX MAX’s 12 GB GDDR6 with 432.0 GB/s. The RTX 5090 Mobile also includes RT cores and tensor cores, which the LX MAX does not list.

The LX MAX has specific advantages in other areas. Its FP16 throughput of 49.15 TFLOPS exceeds the RTX 5090 Mobile’s 31.80 TFLOPS, and its 2:1 FP16 ratio indicates a design aimed at half-precision workloads. Its pixel rate of 192.0 GPixel/s is higher than the RTX 5090 Mobile’s 169.7 GPixel/s. Its memory clock of 2250 MHz is higher than the RTX 5090 Mobile’s 1750 MHz, though the effective bandwidth is lower due to the narrower bus.

The LX MAX is a desktop card with a 225 W TDP, dual-slot cooling, a 16-pin connector, and a 550 W suggested PSU. The RTX 5090 Mobile is an integrated processor with a 95 W TDP and no external power requirement. This makes the RTX 5090 Mobile suitable for portable devices, while the LX MAX is a discrete desktop component.

For users who prioritize raw measured performance, the RTX 5090 Mobile is the only GPU with data to support a conclusion. For users who need half-precision compute or higher pixel throughput, the LX MAX’s specifications suggest potential advantages, but the absence of benchmarks means those advantages remain unverified.

Where Each One Wins

The RTX 5090 Mobile wins in general-purpose compute based on recorded benchmarks. Its average score of 45152 places it above the RTX 4070 Ti by 0.8% and close to the Radeon Pro 5500 XT and Intel Arc A730M. Its percentile of 84 indicates strong standing across all GPUs in the database. The Geekbench OpenCL score of 201834 and Vulkan score of 198405 show solid performance in compute and graphics APIs. The 3DMark Steel Nomad DX12 score of 5871 provides a DirectX 12 gaming data point. The Passmark G3D score of 30034 and GPU compute score of 13401 reinforce its position.

The RTX 5090 Mobile also wins in memory capacity and bandwidth. Its 24 GB GDDR7 with 896.0 GB/s is double the capacity and more than double the bandwidth of the LX MAX. This matters for large datasets, high-resolution textures, and memory-intensive workloads.

The RTX 5090 Mobile wins in FP32 throughput, texture rate, and shading resources. Its 31.80 TFLOPS FP32, 496.9 GTexel/s, 10,496 shading units, 328 TMUs, and 112 ROPs all exceed the LX MAX’s corresponding figures.

The LX MAX wins in half-precision compute. Its 49.15 TFLOPS FP16 with a 2:1 ratio is substantially higher than the RTX 5090 Mobile’s 31.80 TFLOPS at a 1:1 ratio. Applications that use FP16 arithmetic, such as certain AI inference or graphics effects, could benefit from this architecture.

The LX MAX wins in pixel throughput. Its 192.0 GPixel/s exceeds the RTX 5090 Mobile’s 169.7 GPixel/s, which could affect fill-rate-limited scenarios.

The LX MAX wins in physical expansion. It is a dual-slot card with 4x DisplayPort 1.4a outputs and a PCIe 4.0 x16 interface, making it a standard desktop component. The RTX 5090 Mobile is an IGP with no power connectors and portable-device-dependent outputs.

The RTX 5090 Mobile wins in power efficiency. Its 95 W TDP is less than half of the LX MAX’s 225 W TDP, while delivering higher FP32 compute and more memory bandwidth. The RTX 5090 Mobile also supports Vulkan 1.4 versus the LX MAX’s Vulkan 1.3.

The LX MAX has no recorded benchmark scores, so any claim of performance superiority for the LX MAX cannot be supported by the database. The RTX 5090 Mobile’s benchmark presence gives it the only verifiable performance profile. For users selecting a GPU based on measured results, the RTX 5090 Mobile is the clear choice. For users who require the LX MAX’s specific features, such as higher FP16 throughput or a dual-slot desktop form factor, the data offers specifications but no performance validation.
