NVIDIA GeForce RTX 5080 SUPER vs Lisuan Tech LX ULTRA Comparison

Architecture Differences

The NVIDIA GeForce RTX 5080 SUPER and Lisuan Tech LX ULTRA represent fundamentally different design philosophies. The RTX 5080 SUPER is built on NVIDIA's Blackwell 2.0 architecture using the GB203 chip, fabricated on TSMC's 5 nm process. The LX ULTRA uses Lisuan Tech's TrueGPU architecture with the 7G105 chip, produced on a 6 nm process at the same foundry. The process node difference is small, but the architectural decisions diverge sharply.

Transistor counts tell part of the story. The RTX 5080 SUPER packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6 million transistors per square millimeter. The LX ULTRA's transistor count and die size are not recorded in the database, so direct density comparisons are unavailable. What is clear is that NVIDIA chose a much larger, denser chip to deliver its feature set.

The shading engine differs significantly. The RTX 5080 SUPER contains 10,752 shading units, 336 texture mapping units, and 112 render output units. The LX ULTRA counters with 6,144 shading units, 192 TMUs, and 96 ROPs. That is roughly 43% fewer shaders, 43% fewer TMUs, and 14% fewer ROPs for the LX ULTRA. The RTX 5080 SUPER also carries 84 dedicated ray tracing cores and 336 tensor cores, while the LX ULTRA has no recorded RT cores or tensor cores in the database. This indicates a hardware-accelerated ray tracing and AI tensor workload advantage for the NVIDIA part, while the LX ULTRA appears to rely on more general-purpose compute for such tasks.

Clock speeds differ in availability. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost clock of 2617 MHz. The LX ULTRA has no base or boost clocks recorded. Memory clocks are recorded for both: the RTX 5080 SUPER runs at 2000 MHz with 32 Gbps effective data rate, while the LX ULTRA runs at 2250 MHz with 18 Gbps effective. Despite the higher memory clock on the LX ULTRA, the effective data rate is much lower, which directly impacts bandwidth.

Memory architecture is a major divergence. Both cards feature 24 GB of VRAM, but the type and bus width differ. The RTX 5080 SUPER uses GDDR7 on a 256-bit bus, producing 1.02 TB/s of bandwidth. The LX ULTRA uses GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The RTX 5080 SUPER has 2.36 times the memory bandwidth, a critical factor for high-resolution textures and compute workloads that are bandwidth-bound.

Compute throughput also separates them. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 compute and 56.28 TFLOPS of FP16 (at a 1:1 ratio). The LX ULTRA produces 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (at a 2:1 ratio). In FP32, the RTX 5080 SUPER leads by a factor of 2.29. In FP16, the RTX 5080 SUPER still leads, but by a smaller margin of 14.5%, because the LX ULTRA's 2:1 FP16 ratio effectively doubles its FP16 throughput relative to its FP32 rate.

Pixel and texture rates follow the same pattern. The RTX 5080 SUPER achieves 293.1 GPixel/s and 879.3 GTexel/s. The LX ULTRA reaches 192.0 GPixel/s and 384.0 GTexel/s. The NVIDIA part is 52.7% faster in pixel fill and 2.29 times faster in texture fill.

Power and interface specs also differ. The RTX 5080 SUPER has a TDP of 415 W with a single 16-pin connector and no suggested PSU recorded. The LX ULTRA draws 225 W, also with a single 16-pin connector, and the database lists a suggested PSU of 550 W. The RTX 5080 SUPER uses PCIe 5.0 x16, while the LX ULTRA uses PCIe 4.0 x16. Display outputs differ as well: the RTX 5080 SUPER offers 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the LX ULTRA has 4x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6; the RTX 5080 SUPER supports Vulkan 1.4, the LX ULTRA Vulkan 1.3.

Where Each One Wins

The RTX 5080 SUPER wins decisively in raw compute, memory bandwidth, and fill rates. Its 56.28 TFLOPS FP32 performance is more than double the LX ULTRA's 24.58 TFLOPS. Its 1.02 TB/s memory bandwidth dwarfs the LX ULTRA's 432.0 GB/s. For workloads that scale with shader throughput, texture fetches, or memory bandwidth, the RTX 5080 SUPER is the clear choice. This includes high-resolution gaming at maximum detail, ray tracing workloads, and GPU compute tasks such as scientific simulation or AI inference that rely on FP32 or FP16 throughput.

The LX ULTRA wins on power efficiency and physical footprint. Its 225 W TDP is 190 W lower than the RTX 5080 SUPER's 415 W. For a given performance per watt, the LX ULTRA delivers 24.58 TFLOPS within 225 W, whereas the RTX 5080 SUPER delivers 56.28 TFLOPS within 415 W. The efficiency ratios are similar in FP32 per watt (0.109 TFLOPS/W for the LX ULTRA versus 0.136 TFLOPS/W for the RTX 5080 SUPER), so the NVIDIA card is actually more efficient per watt, but the LX ULTRA's absolute power draw is much lower. The LX ULTRA also has a smaller physical profile: 268 mm length, 112 mm height, 40 mm width versus 304 mm length, 137 mm height, 40 mm width for the RTX 5080 SUPER. Both are dual-slot cards, but the LX ULTRA is shorter and lower, making it easier to fit into compact cases.

The LX ULTRA's FP16 capability is its relative strong suit. At 49.15 TFLOPS, it is close to the RTX 5080 SUPER's 56.28 TFLOPS. For workloads that are FP16-heavy, such as certain machine learning inference paths or half-precision graphics effects, the gap narrows substantially. The LX ULTRA also offers four DisplayPort outputs versus the RTX 5080 SUPER's three, which may matter for multi-monitor setups, though the RTX 5080 SUPER's DisplayPort 2.1b supports higher bandwidth per connection.

The RTX 5080 SUPER's hardware ray tracing cores and tensor cores give it a feature advantage that the LX ULTRA cannot match at the hardware level. The database records 84 RT cores and 336 tensor cores for the NVIDIA part, with none recorded for the LX ULTRA. Games or applications that use DXR or Vulkan ray tracing will rely on these dedicated units, and the LX ULTRA would have to emulate or compute those workloads on its general-purpose shaders, which is typically slower.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the RTX 5080 SUPER and the LX ULTRA. The RTX 5080 SUPER has one recorded benchmark score: 3075 in 3DMark Steel Nomad DX12. The LX ULTRA has no benchmark scores recorded at all, so its average benchmark score is 0.

The RTX 5080 SUPER's percentile versus all GPUs is 19, meaning it sits in the 19th percentile of all GPUs in the database. Its nearest rivals in the database provide context. The Intel Arc Pro B60 scores 3182, which is 3.4% higher than the RTX 5080 SUPER. The NVIDIA Quadro P1000 scores 3163, 2.8% higher. The NVIDIA GeForce 820A scores 2983, which is 3.1% lower. The NVIDIA GeForce GTX 860M scores 2967, 3.6% lower. These deltas are small, indicating that the RTX 5080 SUPER's 3075 score is tightly clustered with these competitors.

The LX ULTRA has no nearest rivals listed and no benchmark scores. This makes direct numerical comparison impossible. What the data does show is that the RTX 5080 SUPER has a verified score of 3075 in one DX12 test, while the LX ULTRA's performance is unmeasured in the database.

Given the architectural differences, a projection based on compute and memory metrics is possible. The RTX 5080 SUPER's FP32 rate is 2.29 times the LX ULTRA's. Its texture rate is 2.29 times higher. Its pixel rate is 1.53 times higher. Its memory bandwidth is 2.36 times higher. In FP16, the difference narrows to 1.14 times. These ratios suggest that in FP32-bound DX12 workloads, the RTX 5080 SUPER would likely outperform the LX ULTRA by a wide margin, potentially close to the FP32 ratio. In FP16-bound workloads, the advantage would be much smaller, possibly under 15%.

The single recorded benchmark for the RTX 5080 SUPER is 3075. If the LX ULTRA's performance scales with its FP32 rate relative to the RTX 5080 SUPER, a hypothetical score would be around 1340 in that same test, but the database does not record such a result, and the LX ULTRA's actual behavior may differ due to its distinct TrueGPU architecture.

The Verdict

The recorded data points to the NVIDIA GeForce RTX 5080 SUPER as the superior performer across nearly every measured metric. It has more shading units (10,752 versus 6,144), more TMUs (336 versus 192), more ROPs (112 versus 96), higher FP32 throughput (56.28 TFLOPS versus 24.58 TFLOPS), higher FP16 throughput (56.28 TFLOPS versus 49.15 TFLOPS), higher pixel rate (293.1 GPixel/s versus 192.0 GPixel/s), higher texture rate (879.3 GTexel/s versus 384.0 GTexel/s), and 2.36 times the memory bandwidth. It also has hardware ray tracing and tensor cores, which the LX ULTRA lacks entirely. The RTX 5080 SUPER's benchmark score of 3075 in 3DMark Steel Nomad DX12 is the only recorded performance measurement, and it places the card in the 19th percentile of all GPUs.

The Lisuan Tech LX ULTRA has its own advantages. It draws 190 W less power (225 W TDP versus 415 W), has a smaller physical footprint (268 mm versus 304 mm length, 112 mm versus 137 mm height), and offers four DisplayPort outputs versus three. Its FP16 performance at 49.15 TFLOPS is close to the RTX 5080 SUPER's 56.28 TFLOPS, making it a reasonable option for FP16-centric workloads. But with no recorded benchmark scores and significantly lower FP32, texture, pixel, and bandwidth metrics, the LX ULTRA cannot match the RTX 5080 SUPER for most compute-heavy tasks.

For users prioritizing raw performance, memory bandwidth, ray tracing, and tensor workloads, the data supports the RTX 5080 SUPER. For users prioritizing lower power consumption, a smaller card, and four display outputs, the LX ULTRA is the recorded choice. The RTX 5080 SUPER has a launch MSRP of 999 USD. The LX ULTRA has no recorded launch MSRP.
