NVIDIA GeForce RTX 5090 SE vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the NVIDIA GeForce RTX 5090 SE and the Lisuan Tech LX MAX. Both entries list an average benchmark score of 0 and a percentile versus all GPUs of 50, with no nearest rivals specified. This absence of measured data means the comparison must rely entirely on the architectural and specification fields provided.

The RTX 5090 SE shows a peak FP32 compute of 66.94 TFLOPS, while the LX MAX delivers 24.58 TFLOPS in FP32. That places the NVIDIA part at roughly 2.7 times the raw single-precision throughput of the Lisuan Tech card. In FP16, the RTX 5090 SE maintains 66.94 TFLOPS with a 1:1 ratio, whereas the LX MAX reaches 49.15 TFLOPS using a 2:1 ratio. The NVIDIA card still leads in FP16, but the gap narrows to about 1.36 times, reflecting the Lisuan Tech part's doubled rate in half-precision operations.

Pixel fill rate favors the RTX 5090 SE at 380.3 GPixel/s against 192.0 GPixel/s for the LX MAX, a 1.98x advantage. Texture fill rate shows a larger divide: 1,045.9 GTexel/s versus 384.0 GTexel/s, a 2.72x lead for NVIDIA. Memory bandwidth follows a similar pattern, with the RTX 5090 SE delivering 1.34 TB/s over a 384-bit bus, while the LX MAX provides 432.0 GB/s over a 192-bit bus, a 3.1x difference.

Because no benchmark scores exist in the database, every performance statement above derives from theoretical peak rates and memory subsystem figures. The data indicates the RTX 5090 SE holds a commanding lead across all measured throughput categories, but the absence of application-level results leaves real-world behavior unquantified.

Architecture Differences

The two GPUs originate from different design philosophies. The RTX 5090 SE uses the GB202 chip built on NVIDIA's Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The LX MAX uses the 7G106 chip with an architecture called TrueGPU, also produced by TSMC but on a 6 nm node. Both use the same foundry, yet the process node differs by one step, with NVIDIA on the smaller geometry.

Transistor counts highlight a major divergence. The RTX 5090 SE integrates 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9M per mm². The LX MAX lists its transistor count and die size as unknown, so no density figure exists in the database. The NVIDIA chip's die area is nearly three times larger than a typical mid-range GPU, but without the LX MAX die size, a direct comparison is impossible.

Memory architecture differs substantially. The RTX 5090 SE pairs 24 GB of GDDR7 with a 384-bit bus and 1.34 TB/s bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. Effective memory clock rates also diverge: 28 Gbps for the NVIDIA card versus 18 Gbps for the Lisuan Tech part. The RTX 5090 SE has double the capacity, double the bus width, and roughly triple the bandwidth.

Core configurations show a wide gap. The RTX 5090 SE contains 14,080 shading units, 440 texture mapping units, 160 ROPs, 110 RT cores, and 440 tensor cores. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT cores or tensor cores listed in the database. The absence of RT and tensor core data for the LX MAX suggests either a different compute approach or unrecorded specifications.

Clock behavior differs as well. The RTX 5090 SE has explicit base and boost clocks of 1740 MHz and 2377 MHz, respectively. The LX MAX lists no base or boost clock values, only a memory clock of 2250 MHz with 18 Gbps effective. This makes sustained frequency comparisons impossible from the recorded data.

API support shows both cards reaching DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5090 SE supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Display outputs also differ: the NVIDIA card offers one HDMI 2.1b and three DisplayPort 2.1b connections, whereas the LX MAX provides four DisplayPort 1.4a outputs with no HDMI.

Interface generations separate the two further. The RTX 5090 SE uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. Power requirements reflect the performance divide: the RTX 5090 SE carries a 500 W TDP with a suggested 900 W PSU, and the LX MAX draws 225 W with a suggested 550 W PSU. Both use a single 16-pin power connector and occupy dual-slot form factors.

Where Each One Wins

The RTX 5090 SE wins in every category where the database records comparable specifications. Raw compute throughput, pixel fill, texture fill, memory bandwidth, memory capacity, and interface bandwidth all favor the NVIDIA part by wide margins. The FP32 rate of 66.94 TFLOPS versus 24.58 TFLOPS positions the RTX 5090 SE for compute-heavy workloads such as scientific simulation, rendering, and high-end gaming at extreme resolutions. The 24 GB frame buffer allows larger datasets and textures to reside locally, reducing reliance on system memory.

The LX MAX does hold advantages in specific areas. Its FP16 performance of 49.15 TFLOPS at a 2:1 ratio means it processes half-precision workloads more efficiently relative to its FP32 capability. For machine learning inference or workloads that accept reduced precision, the LX MAX extracts proportionally more throughput from its hardware than the RTX 5090 SE does from its own FP16 path, even though the absolute FP16 number remains lower. The LX MAX also has a lower TDP of 225 W compared to 500 W, suggesting it operates within a tighter power envelope, though the database provides no measured efficiency metrics.

Physical dimensions favor the LX MAX in length and width: 248 mm versus 267 mm in length, and 48 mm versus 40 mm in width (the LX MAX is wider but shorter). The LX MAX is also taller at 118 mm versus 111 mm. These differences may matter for chassis compatibility, but the database does not include thermal or noise measurements.

The LX MAX's release date of 2026-03-16 comes after the RTX 5090 SE's 2025-12-31, making the Lisuan Tech part a later entry. Its production status is active, as is the NVIDIA card's. No successor or predecessor is listed for the LX MAX, while the RTX 5090 SE has the GeForce 40 as predecessor and GeForce 60 as successor.

The Verdict

The recorded data presents a clear hierarchy. The NVIDIA GeForce RTX 5090 SE outperforms the Lisuan Tech LX MAX in every measured throughput metric: FP32 by 2.7x, FP16 by 1.36x, pixel fill by 1.98x, texture fill by 2.72x, and memory bandwidth by 3.1x. It also carries double the memory capacity, a newer memory type, a wider bus, more shading units, and dedicated RT and tensor cores that the LX MAX lacks entirely.

The LX MAX offers a lower power draw at 225 W versus 500 W, a smaller physical footprint in length, and a later release date. Its FP16 ratio of 2:1 indicates a design optimized for half-precision throughput relative to its FP32 capability, which may suit specific reduced-precision workloads. However, without RT cores, tensor cores, or benchmark scores, its application-level utility remains unverified in the database.

For users prioritizing peak compute, memory bandwidth, or feature completeness, the RTX 5090 SE is the only choice supported by the data. For scenarios constrained by power draw or chassis space, the LX MAX presents a more modest alternative, but the absence of measured performance means its real-world competitiveness cannot be confirmed. The database records no benchmark results for either card, so the verdict rests entirely on architectural specifications and theoretical peak rates.
