NVIDIA GeForce RTX 5080 vs Lisuan Tech LX ULTRA Comparison

NVIDIA GeForce RTX 5080 vs Lisuan Tech LX ULTRA

The comparison between the NVIDIA GeForce RTX 5080 and the Lisuan Tech LX ULTRA presents an unusual pairing, as the database contains a complete set of benchmark results for the NVIDIA card while the Lisuan Tech card has no recorded scores. The RTX 5080 sits in the 87th percentile among all GPUs in the database, with an average benchmark score of 56083. The LX ULTRA, by contrast, holds a 50th percentile placement with no average score recorded. This asymmetry shapes the analysis: the RTX 5080 can be measured against established rivals, while the LX ULTRA must be assessed through its architectural specifications alone.

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist between these two cards in the database. The RTX 5080, however, has a full suite of scores across multiple testing applications. Its 3DMark Steel Nomad DX12 result stands at 8637 points. In Geekbench compute tests, the card records 235901 points in OpenCL and 255450 points in Vulkan. Passmark results show a G3D score of 36565, a GPU compute score of 21789, and legacy DirectX scores of 389 for DX9, 324 for DX11, 208 for DX10, and 151 for DX12. The 2D passmark score reaches 1415.

Because the LX ULTRA has no benchmark entries, the database cannot produce a direct percentage comparison. The RTX 5080's nearest rivals provide context for its standing. The AMD Radeon 8060S averages 55757 points, a 0.6 percent difference from the RTX 5080. The AMD Radeon RX 6750 GRE 12 GB scores 55698 on average, also a 0.7 percent difference. The AMD Radeon Pro W5700X trails at 54828 points, 2.3 percent behind. The AMD Radeon RX 9070 GRE leads the RTX 5080 by 2.2 percent with an average of 57367 points.

These figures indicate the RTX 5080 sits in a tight cluster of competing cards. The narrow margins, all within 2.3 percent of the RTX 5080, suggest performance parity among this group. The RX 9070 GRE is the only one of these rivals to exceed the RTX 5080's average score. The LX ULTRA, lacking any recorded results, cannot be placed within this ranking.

Architecture Differences

The two cards diverge fundamentally in their underlying designs. The RTX 5080 uses the GB203 chip built on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The chip contains 45,600 million transistors across a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The LX ULTRA uses the 7G105 chip with the TrueGPU architecture, also produced by TSMC but on a 6 nm node. Its transistor count and die size are not recorded in the database.

The RTX 5080's Blackwell 2.0 architecture features 10752 shading units, 336 texture mapping units, and 112 raster operation pipelines. It includes 84 ray tracing cores and 336 tensor cores. The LX ULTRA carries 6144 shading units, 192 texture mapping units, and 96 raster operations pipelines. The database lists no ray tracing cores or tensor cores for the LX ULTRA.

Clock behavior differs as well. The RTX 5080 has a base clock of 2295 MHz and a boost clock of 2617 MHz. The LX ULTRA lists no base or boost clock values. Memory clocks show 1875 MHz with 30 Gbps effective transfer for the RTX 5080, while the LX ULTRA runs its memory at 2250 MHz with 18 Gbps effective.

Compute throughput marks a major separation. The RTX 5080 delivers 56.28 TFLOPS in FP32 and the same 56.28 TFLOPS in FP16 with a 1:1 ratio. The LX ULTRA produces 24.58 TFLOPS in FP32 and 49.15 TFLOPS in FP16 with a 2:1 ratio. The RTX 5080 more than doubles the LX ULTRA's single-precision output, while the LX ULTRA's FP16 figure reaches close to the RTX 5080's because of its 2:1 architecture.

The RTX 5080 achieves pixel and texture rates of 293.1 GPixel/s and 879.3 GTexel/s respectively. The LX ULTRA records 192.0 GPixel/s and 384.0 GTexel/s. The RTX 5080 leads in both categories, with the texture rate gap being particularly large at more than double.

API support shows partial overlap. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5080 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3.

The Verdict

The recorded data shows a clear separation in measured performance. The RTX 5080 posts an average benchmark score of 56083, placing it in the 87th percentile of all GPUs. Its nearest rivals sit within a 2.3 percent band, confirming its position among competitive cards. The LX ULTRA has no benchmark results, an average score of zero, and a 50th percentile placement. Without measurements, the database cannot validate its real-world performance.

The architectural data reinforces this gap. The RTX 5080 delivers 56.28 TFLOPS in FP32, more than double the LX ULTRA's 24.58 TFLOPS. Its memory bandwidth of 960.0 GB/s exceeds the LX ULTRA's 432.0 GB/s by a wide margin. Texture rate stands at 879.3 GTexel/s versus 384.0 GTexel/s. These figures indicate the RTX 5080 holds a substantial lead in raw compute throughput.

The LX ULTRA does offer advantages in specific areas. Its 24 GB memory capacity exceeds the RTX 5080's 16 GB. Its 225 W thermal design power is lower than the RTX 5080's 360 W, and its suggested power supply of 550 W is below the RTX 5080's 750 W. Its FP16 output of 49.15 TFLOPS approaches the RTX 5080's 56.28 TFLOPS, supported by the 2:1 FP16 ratio.

The verdict depends on what the buyer prioritizes. Measured performance and established benchmark standing favor the RTX 5080. The LX ULTRA presents a larger memory pool and a lower power footprint, but its lack of recorded results leaves its actual performance unverified.

Where Each One Wins

The RTX 5080 wins in every measured performance category. Its FP32 compute is 56.28 TFLOPS, its pixel rate is 293.1 GPixel/s, and its texture rate is 879.3 GTexel/s. Memory bandwidth of 960.0 GB/s provides the data throughput needed for high-resolution workloads. Its 84 ray tracing cores and 336 tensor cores give it dedicated hardware for ray-traced rendering and AI-assisted features. The PCIe 5.0 x16 interface offers a newer bus generation than the LX ULTRA's PCIe 4.0 x16.

The LX ULTRA wins on memory capacity with 24 GB versus 16 GB. This larger pool could benefit workloads that require holding substantial data sets in VRAM. Its 225 W thermal design power and 550 W suggested power supply make it a lower-power option, potentially easier to integrate into systems with modest power budgets. Its 4x DisplayPort 1.4a outputs exceed the RTX 5080's 3x DisplayPort 2.1b in port count, though the RTX 5080's DisplayPort 2.1b standard is newer. The LX ULTRA's FP16 throughput of 49.15 TFLOPS, while lower than the RTX 5080's 56.28 TFLOPS, still comes closer to parity than its FP32 figures.

The RTX 5080's benchmark presence gives it a verifiable track record. The LX ULTRA's absence of recorded scores means its advantages in memory capacity and power draw remain theoretical until measured. The data supports the RTX 5080 as the stronger performer in compute-intensive scenarios, while the LX ULTRA offers a larger memory allocation and a more efficient power profile on paper.
