Architecture Differences

The RTX 5090 is built on NVIDIA's Blackwell 2.0 architecture, using the GB202 chip, and belongs to the GeForce 50-series generation. It is manufactured on a 5 nm process at TSMC with 92,200 million transistors on a 750 mm² die, resulting in a transistor density of 122.9M per mm². The chip integrates 21,760 shading units, 680 texture mapping units, 176 ROPs, 170 RT cores, and 680 tensor cores.

The Lisuan Tech LX ULTRA uses a completely different design, labeled "TrueGPU" architecture with the 7G105 chip and a generation designation of 7G100. It is fabricated on a 6 nm process at TSMC, though transistor count and die size are not recorded in the database. The LX ULTRA has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT core or tensor core counts listed. This indicates a fundamentally different compute layout, likely optimized for rasterization rather than hybrid ray tracing or AI acceleration.

Memory architecture differs sharply. The RTX 5090 uses 32 GB of GDDR7 across a 512-bit interface, delivering 1.79 TB/s of bandwidth. Memory clocks run at 1750 MHz with an effective data rate of 28 Gbps. The LX ULTRA uses 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. Its memory clock is 2250 MHz with an effective rate of 18 Gbps. The RTX 5090's memory subsystem provides over four times the bandwidth, which matters for high-resolution textures and compute workloads.

API support is similar but not identical. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5090 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RTX 5090 also offers a dual-slot form factor with a 16-pin power connector and a suggested PSU of 950 W, whereas the LX ULTRA is also dual-slot with the same 16-pin connector but a suggested PSU of 550 W.

Display outputs differ: the RTX 5090 provides one HDMI 2.1b port and three DisplayPort 2.1b outputs, while the LX ULTRA offers four DisplayPort 1.4a outputs with no HDMI port. The RTX 5090 uses PCIe 5.0 x16, the LX ULTRA uses PCIe 4.0 x16. The RTX 5090 has a longer board at 304 mm versus 268 mm for the LX ULTRA, and a taller height of 137 mm versus 112 mm, while both share the same 40 mm width.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RTX 5090 and the LX ULTRA, and no win counts are recorded for either side. However, the available benchmark data for the RTX 5090 allows for indirect comparisons against the broader GPU field.

The RTX 5090 scores 18,355 in 3DMark Steel Nomad DX12, 334,370 in Geekbench OpenCL, and 376,728 in Geekbench Vulkan. In Passmark tests, it records 226 in DirectX 10, 341 in DirectX 11, 185 in DirectX 12, 395 in DirectX 9, 1,413 in G2D, 39,650 in G3D, and 26,756 in GPU compute. These scores place the card in the 92nd percentile of all GPUs.

The nearest rival data shows the RTX 5090's average score of 79,842 sits just 0.3% above the Tesla P100 PCIe 16 GB (79,605) and 0.6% above the Tesla P100 PCIe 12 GB (79,396). It is also 1.1% ahead of the AMD Radeon RX 6850M XT (78,940). Conversely, it trails the AMD Radeon Pro Vega 64X (80,959) by 1.4%. These margins are narrow, indicating that the RTX 5090's average score is closely clustered with several other high-end accelerators, though the RTX 5090's raw specifications suggest it should dominate in pure rasterization and ray tracing workloads.

The LX ULTRA, by contrast, has no benchmark scores recorded, no nearest rivals listed, and an average score of zero. Its 50th percentile ranking implies it sits at the median of the database, but without actual test data, no quantitative comparison can be drawn against the RTX 5090's measured results. The specification differences, however, are stark: the RTX 5090 delivers 104.8 TFLOPS FP32 versus 24.58 TFLOPS, 1.79 TB/s bandwidth versus 432.0 GB/s, and 32 GB versus 24 GB of memory. These numbers indicate a substantial performance gap in compute throughput and memory bandwidth, even if direct benchmark comparisons are absent.

The Verdict

The data shows a clear segmentation between the two cards. The RTX 5090 is a high-end, actively produced GPU with a 92nd percentile ranking, a full suite of recorded benchmarks, and a launch MSRP of 1,999 USD. Its FP32 throughput of 104.8 TFLOPS, 1.79 TB/s memory bandwidth, and 32 GB of GDDR7 memory position it as a top-tier performer for compute-heavy and high-resolution workloads. The card's nearest rivals in the database, such as the Tesla P100 PCIe 16 GB, are within 0.3% of its average score, indicating that the RTX 5090 is competitive but not decisively ahead of other accelerators in aggregate benchmark terms.

The Lisuan Tech LX ULTRA presents a different profile. With no benchmark scores, no rivals, and a 50th percentile ranking, its actual performance is unverified in the database. Its specifications, including 24.58 TFLOPS FP32, 432.0 GB/s bandwidth, and 24 GB GDDR6, are substantially lower than the RTX 5090's. The LX ULTRA's 225 W TDP and 550 W suggested PSU also indicate a lower power envelope compared to the RTX 5090's 575 W TDP and 950 W suggested PSU.

For users seeking maximum compute and bandwidth, the RTX 5090 is the only card with measured results, and those results place it near the top of the database. For users prioritizing lower power consumption and smaller physical size, the LX ULTRA offers a more compact board (268 mm versus 304 mm) and a reduced PSU requirement, but with no benchmark confirmation of its capabilities. The choice hinges on whether the LX ULTRA's unverified performance meets the workload demands, or whether the RTX 5090's recorded scores justify its higher power and system requirements.
