NVIDIA RTX 4000 Mobile Ada Generation vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark scores for either part, as both entries carry empty benchmark arrays. However, the raw specification sheet allows for meaningful theoretical comparisons. The NVIDIA RTX 4000 Mobile Ada Generation and the Lisuan Tech LX ULTRA are nearly tied in raw FP32 compute, with the NVIDIA part delivering 24.72 TFLOPS against the Lisuan's 24.58 TFLOPS, a difference of only 0.14 TFLOPS (roughly 0.6% in favor of NVIDIA). This places both firmly in the same performance class for single-precision workloads.

The Lisuan Tech LX ULTRA counters decisively in FP16 throughput. Its 49.15 TFLOPS at a 2:1 ratio is exactly double its FP32 rate, while the NVIDIA RTX 4000 Mobile Ada Generation achieves 24.72 TFLOPS at a 1:1 ratio, meaning its FP16 performance is identical to its FP32. The LX ULTRA therefore holds a 98.9% advantage in half-precision compute, a significant margin for AI inference or machine learning training tasks that rely on FP16 arithmetic.

Pixel throughput tells a similar story. The Lisuan part reaches 192.0 GPixel/s, which is 44.1% higher than the NVIDIA's 133.2 GPixel/s. This advantage stems from its 96 ROPs versus 80 ROPs on the RTX 4000 Mobile Ada Generation. In rasterization-heavy workloads, especially at high resolutions with heavy overdraw, the LX ULTRA should show measurably better fill-rate performance.

Texture rate is closer. The Lisuan Tech LX ULTRA delivers 384.0 GTexel/s, while the NVIDIA part achieves 386.3 GTexel/s, a marginal 0.6% edge for NVIDIA. This near-parity reflects the balance between the Lisuan's 192 TMUs and the NVIDIA's 232 TMUs, offset by the NVIDIA's higher clock behavior.

The NVIDIA RTX 4000 Mobile Ada Generation does not have a listed base or boost clock in the database, so a direct clock-for-clock comparison is not possible. The Lisuan Tech LX ULTRA also lacks base and boost clock entries, meaning all computed rates derive from the effective memory clock and architectural ratios provided.

In terms of memory configuration, both cards use GDDR6 with a 192-bit bus and exactly 432.0 GB/s of bandwidth. Memory size differs substantially: the Lisuan Tech LX ULTRA carries 24 GB, while the NVIDIA RTX 4000 Mobile Ada Generation has 12 GB. For datasets or rendering scenes that exceed 12 GB, the LX ULTRA has a hard capacity advantage that no clock speed can compensate for.

The NVIDIA part wins on features that the Lisuan lacks entirely. It includes 58 RT cores and 232 Tensor cores, while the LX ULTRA lists no RT core or Tensor core counts. Any ray-traced workload or tensor-accelerated operation will only run on the NVIDIA hardware. The Lisuan's Vulkan support is 1.3 versus NVIDIA's 1.4, and its DirectX and OpenGL support match at 12 Ultimate (12_2) and 4.6 respectively.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA RTX 4000 Mobile Ada Generation uses the AD104 chip built on Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. It packs 35,800 million transistors into a 294 mm² die, yielding a transistor density of 121.8M per mm². The Lisuan Tech LX ULTRA uses the 7G105 chip under the "TrueGPU" architecture, fabricated on a 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown, so a density comparison is impossible.

The NVIDIA part belongs to the GeForce 40-series, with a generation tag of "Ada-MW" and a predecessor of "Ampere-MW" and successor of "Blackwell-MW". The Lisuan Tech LX ULTRA sits in the "7G100" generation with no predecessor or successor listed. The NVIDIA GPU was released on 2023-03-20, while the Lisuan part has a release date of 2026-03-16, three years later in the database.

Shading unit counts differ: the NVIDIA GPU has 7424 shading units, while the Lisuan has 6144, a 20.8% higher count for NVIDIA. However, the Lisuan part compensates with 96 ROPs versus 80, and the FP32 gap is minimal due to clock rate assumptions embedded in the TFLOPS figures. The NVIDIA part has 232 TMUs and 232 Tensor cores, while the Lisuan has 192 TMUs and no Tensor core count.

The NVIDIA RTX 4000 Mobile Ada Generation is an integrated graphics processor (IGP) with a slot width of "IGP" and no power connectors. It has a TDP of 110 W and display outputs marked "Portable Device Dependent", indicating it is designed for mobile workstations where the display path is determined by the laptop. The Lisuan Tech LX ULTRA is a dual-slot discrete card measuring 268 mm by 112 mm by 40 mm, requiring a single 16-pin power connector and a 550 W suggested PSU. Its display outputs are 4x DisplayPort 1.4a.

Both use PCIe 4.0 x16 as the bus interface. The Lisuan's memory clock is listed at 2250 MHz with 18 Gbps effective, identical to the NVIDIA's memory clock entry. Both achieve 432.0 GB/s bandwidth over a 192-bit bus.

The Lisuan's FP16 ratio is 2:1 versus NVIDIA's 1:1, indicating a fundamentally different FP16 execution path, likely using packed arithmetic units rather than dedicated FP16 hardware. This explains the doubling of FP16 throughput despite nearly identical FP32 rates.

The Verdict

The data points to two very different design philosophies. The NVIDIA RTX 4000 Mobile Ada Generation is a mobile-first integrated GPU optimized for a 110 W power envelope, packing 58 RT cores, 232 Tensor cores, and a 5 nm process into an IGP form factor. Its strengths are ray tracing acceleration, tensor operations, and a compact footprint suitable for portable devices. The 12 GB memory capacity is adequate for many workloads but may limit large dataset handling.

The Lisuan Tech LX ULTRA is a desktop-oriented dual-slot card with a 225 W TDP, requiring a 550 W PSU and a 16-pin connector. It doubles the memory to 24 GB, offers 44.1% higher pixel rate, and doubles FP16 throughput. Its 6 nm process and unknown transistor count suggest a different implementation strategy, but the absence of RT and Tensor cores means it cannot accelerate ray-traced or tensor workloads. Vulkan 1.3 support is one version behind the NVIDIA's 1.4.

For users prioritizing ray tracing, AI acceleration via Tensor cores, or low-power mobile integration, the NVIDIA RTX 4000 Mobile Ada Generation is the only choice. For users needing maximum memory capacity, higher pixel fill rate, or double-precision half-rate FP16 compute, the Lisuan Tech LX ULTRA provides clear advantages. The near-identical FP32 and texture rates mean standard rasterized gaming or general compute will perform similarly, assuming both are within their respective power and form factor constraints. The Lisuan's 24 GB capacity is its strongest argument, especially for large-scale rendering or machine learning datasets that exceed 12 GB. The NVIDIA's architectural features are its strongest argument, particularly for modern ray-traced titles or frameworks that rely on Tensor Core acceleration.
