Architecture Differences

The two GPUs come from fundamentally different design backgrounds. The NVIDIA RTX 5000 Mobile Ada Generation uses the AD103 chip built on TSMC's 5 nm process, with an architecture called Ada Lovelace. It belongs to the Ada-MW generation and is part of the GeForce 50-series product line. The Lisuan Tech LX ULTRA uses the 7G105 chip on a 6 nm process from the same foundry, TSMC, with an architecture designated TrueGPU and a generation label of 7G100.

The RTX 5000 Mobile integrates 45,900 million transistors on a 379 mm² die, resulting in a transistor density of 121.1 million per mm². The LX ULTRA does not report transistor count, die size, or density in the database, so those structural details remain unknown.

Feature support also diverges. Both GPUs support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5000 Mobile supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RTX 5000 Mobile includes 76 ray tracing cores and 304 tensor cores, while the LX ULTRA does not report any RT core or tensor core counts.

The compute ratios differ notably. The RTX 5000 Mobile runs FP32 and FP16 at a 1:1 ratio, both at 41.15 TFLOPS. The LX ULTRA runs FP16 at a 2:1 ratio, meaning its FP16 output of 49.15 TFLOPS is double its FP32 output of 24.58 TFLOPS. This indicates different design priorities for mixed-precision workloads.

The RTX 5000 Mobile is a mobile integrated solution with no slot width, no power connectors, and portable device dependent outputs. The LX ULTRA is a standalone dual-slot card with a 16-pin connector, a 550 W suggested power supply, and four fixed DisplayPort outputs. The LX ULTRA also has defined physical dimensions of 268 mm length, 112 mm height, and 40 mm width.

Where Each One Wins

Based on the recorded data, the RTX 5000 Mobile wins in several clear categories. It has higher FP32 throughput at 41.15 TFLOPS versus 24.58 TFLOPS, giving it a 67% advantage in single-precision compute. Its texture rate of 643.0 GTexel/s is 67% higher than the LX ULTRA's 384.0 GTexel/s. Its pixel rate of 236.9 GPixel/s exceeds the LX ULTRA's 192.0 GPixel/s by 23%. Its memory bandwidth of 576.0 GB/s is 33% higher than the LX ULTRA's 432.0 GB/s. It also supports Vulkan 1.4, a newer API version than the LX ULTRA's Vulkan 1.3.

The LX ULTRA wins in memory capacity, offering 24 GB versus 16 GB, a 50% advantage. It also has significantly higher FP16 throughput at 49.15 TFLOPS versus 41.15 TFLOPS, an advantage of roughly 19%. The LX ULTRA's TDP of 225 W is higher than the RTX 5000 Mobile's 120 W, which indicates the LX ULTRA is designed for a desktop card form factor with dedicated cooling rather than mobile integration.

The RTX 5000 Mobile wins on power efficiency characteristics, delivering higher FP32 performance at nearly half the power draw. The LX ULTRA wins on raw FP16 compute and memory capacity, making it potentially better suited for workloads that rely on large datasets or half-precision math.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs, and winsA and winsB are both recorded as zero. The RTX 5000 Mobile has a single benchmark score of 3596 in 3DMark Steel Nomad DX12, while the LX ULTRA has no benchmark records at all.

The RTX 5000 Mobile's score of 3596 positions it near several older NVIDIA and AMD parts. The nearest rival is the NVIDIA GeForce GT 545 with an average score of 3594, a delta of 0.1% in favor of the RTX 5000 Mobile. The NVIDIA GeForce GT 735M scores 3616, which is 0.6% higher. The NVIDIA GeForce GTX 1050 scores 3629, which is 0.9% higher. The AMD Radeon HD 6770 scores 3649, which is 1.5% higher. These deltas are small, indicating the RTX 5000 Mobile's recorded benchmark performance is closely matched with these considerably older and lower-tier cards.

The RTX 5000 Mobile sits at the 21st percentile among all GPUs in the database. That means roughly four out of five recorded GPUs outperform it in the Steel Nomad DX12 test. This is a notable result given the RTX 5000 Mobile has 9728 shading units, 304 TMUs, and 112 ROPs.

The LX ULTRA has no benchmark scores and no nearest rivals recorded. Its percentile is listed at 50, but with an average benchmark score of zero, this percentile likely reflects a default or unmeasured state rather than observed performance. The absence of benchmark data means the LX ULTRA's actual performance cannot be assessed from the database.

The Verdict

The data supports a clear split between these two GPUs based on use case. The NVIDIA RTX 5000 Mobile Ada Generation is the measured performer. It holds a recorded 3DMark Steel Nomad DX12 score of 3596, placing it at the 21st percentile. It delivers 41.15 TFLOPS of FP32, 576.0 GB/s of memory bandwidth, and a texture rate of 643.0 GTexel/s. It includes ray tracing cores and tensor cores, which the LX ULTRA does not report. It also runs at 120 W with an integrated form factor, making it suitable for mobile workstations.

The Lisuan Tech LX ULTRA is the unmeasured alternative. It offers 24 GB of memory, which is 50% more than the RTX 5000 Mobile. Its FP16 throughput of 49.15 TFLOPS exceeds the RTX 5000 Mobile's 41.15 TFLOPS. It provides four fixed DisplayPort outputs and a dual-slot desktop design with a 225 W TDP and a 550 W suggested power supply. However, with no benchmark scores in the database, its real-world performance cannot be verified or compared directly.

For users prioritizing verified performance, compute features like ray tracing and tensor cores, and mobile integration, the RTX 5000 Mobile is the data-backed choice. For users needing maximum memory capacity, higher half-precision throughput, and a desktop card form factor, the LX ULTRA offers those specifications on paper, but the absence of recorded measurements means its actual performance remains unknown.

The RTX 5000 Mobile's benchmark score of 3596 is nearly identical to the GeForce GT 545 (3594), GT 735M (3616), GTX 1050 (3629), and Radeon HD 6770 (3649), all within 1.5% of each other. This clustering suggests the RTX 5000 Mobile's measured performance is modest relative to its high-end specification list. The LX ULTRA cannot be placed on this scale without recorded data.

The decision between these two GPUs depends on whether the user trusts measured results or unverified specifications. The database contains evidence for the RTX 5000 Mobile and only specifications for the LX ULTRA.
