NVIDIA Switch 2 GPU vs Lisuan Tech LX ULTRA Comparison

NVIDIA Switch 2 GPU vs Lisuan Tech LX ULTRA

The NVIDIA Switch 2 GPU is a console-oriented Ampere part built for the Nintendo platform, while the Lisuan Tech LX ULTRA is a dual-slot desktop card from an unknown manufacturer targeting the 7G100 generation. The database lists both with a 50th percentile score against all GPUs, but their raw specifications diverge sharply in compute, memory, and power envelope. The Switch 2 GPU operates at a 40 W TDP with 4.301 TFLOPS FP32, while the LX ULTRA reaches 24.58 TFLOPS FP32 at 225 W. These are fundamentally different products, and the recorded data shows the LX ULTRA dominates in raw throughput, while the Switch 2 GPU offers a compact, low-power form factor with no display outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs, and both have zero measured average benchmark scores. However, the specification sheets allow a comparative analysis of theoretical performance ceilings. The LX ULTRA delivers 24.58 TFLOPS FP32, which is 5.7 times the 4.301 TFLOPS of the Switch 2 GPU. In FP16, the LX ULTRA reaches 49.15 TFLOPS versus 8.602 TFLOPS, a 5.7x gap as well. The pixel rate tells a similar story: the LX ULTRA outputs 192.0 GPixel/s, while the Switch 2 GPU manages 22.40 GPixel/s, an 8.6x difference. Texture rate is even more lopsided, with the LX ULTRA at 384.0 GTexel/s compared to 67.20 GTexel/s, a 5.7x margin.

Memory bandwidth heavily favors the LX ULTRA. It uses a 192 bit bus with GDDR6 at 18 Gbps effective, yielding 432.0 GB/s. The Switch 2 GPU relies on a 128 bit LPDDR5X bus at 6.4 Gbps effective, producing 102.4 GB/s. That is a 4.2x bandwidth advantage for the LX ULTRA. The LX ULTRA also has 24 GB of memory, double the 12 GB on the Switch 2 GPU. Shader resources follow the same pattern: the LX ULTRA has 6144 shading units, 192 TMUs, and 96 ROPs, versus 1536 shading units, 48 TMUs, and 16 ROPs on the Switch 2 GPU. The LX ULTRA has 4x the shading units, 4x the TMUs, and 6x the ROPs.

The Switch 2 GPU does hold advantages in a few areas. Its base clock of 561 MHz and boost clock of 1400 MHz are explicitly listed, whereas the LX ULTRA has no recorded base or boost clock. The Switch 2 GPU also includes 12 RT cores and 48 tensor cores, while the LX ULTRA lists no RT cores or tensor cores in its specification. That said, the absence of those fields does not confirm their non-existence, but the database records them as null. The Switch 2 GPU supports Vulkan 1.4, while the LX ULTRA is listed with Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

Power efficiency is where the Switch 2 GPU shines. Its 40 W TDP is 5.6x lower than the 225 W TDP of the LX ULTRA. Per watt, the Switch 2 GPU delivers 0.1075 TFLOPS/W, while the LX ULTRA delivers 0.1092 TFLOPS/W. Those figures are nearly identical, meaning the LX ULTRA is only marginally more efficient despite its much larger power budget. The LX ULTRA requires a 550 W suggested PSU and a 1x 16-pin connector, while the Switch 2 GPU lists no power connectors and no suggested PSU. The Switch 2 GPU is also physically smaller: 272 mm long, 116 mm tall, and 14 mm wide, versus the LX ULTRA at 268 mm long, 112 mm tall, and 40 mm wide. The LX ULTRA is a dual-slot card, while the Switch 2 GPU has no recorded slot width.

Given the lack of direct benchmark results, the head-to-head comparison rests entirely on theoretical specifications. The LX ULTRA is unequivocally the faster part in every measurable compute and memory metric. The Switch 2 GPU counters with lower power draw, integrated tensor and RT cores, and a slimmer profile.

The Verdict

The data indicates a clear split. The Lisuan Tech LX ULTRA is for workloads demanding maximum throughput: high-resolution rendering, compute-heavy tasks, and large memory buffers. Its 24.58 TFLOPS FP32, 432.0 GB/s bandwidth, and 24 GB VRAM make it the obvious choice for any application where raw performance is the priority. The 225 W TDP and 550 W suggested PSU reflect a desktop-oriented design that assumes a full power supply.

The NVIDIA Switch 2 GPU is for constrained environments. Its 40 W TDP, 12 GB memory, and 102.4 GB/s bandwidth are far lower, but it includes RT cores, tensor cores, and fits in a 14 mm thick package. The lack of display outputs confirms its role as an embedded or console GPU, not a standalone desktop card. Users who need a compact, low-power solution with AI and ray tracing acceleration should favor the Switch 2 GPU. Users who need maximum frame rates or compute density should choose the LX ULTRA. The 50th percentile ranking for both GPUs in the database suggests they sit at similar overall performance levels relative to all GPUs, but that percentile is based on no actual benchmark scores, so it carries limited weight.

Architecture Differences

The NVIDIA Switch 2 GPU is built on the Ampere architecture using the GA10B chip. It is classified as a console GPU for Nintendo. The process node is 8 nm from Samsung, and the die measures 200 mm². The LX ULTRA uses the TrueGPU architecture with the 7G105 chip, belonging to the 7G100 generation. Its process node is 6 nm from TSMC, with no die size recorded. The Switch 2 GPU integrates RT cores and tensor cores, which are absent from the LX ULTRA specification. The Switch 2 GPU supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Switch 2 GPU has no display outputs, indicating an architecture designed for internal rendering, while the LX ULTRA has 4x DisplayPort 1.4a for external monitors. The Switch 2 GPU uses LPDDR5X memory, which is typically soldered and low-power, while the LX ULTRA uses GDDR6, which is standard for desktop graphics cards. The Switch 2 GPU lists a base clock and boost clock, while the LX ULTRA has no clock speeds recorded. The LX ULTRA has a 192 bit memory bus and 24 GB VRAM, suggesting a memory architecture built for large datasets, while the Switch 2 GPU has a 128 bit bus and 12 GB, indicating a more modest memory subsystem. The transistor counts are unknown for both, but the die size for the Switch 2 GPU is known at 200 mm², while the LX ULTRA die size is unknown.

Where Each One Wins

The Switch 2 GPU wins in power-constrained scenarios. Its 40 W TDP allows operation without a dedicated power connector, and its 14 mm thickness fits into slim enclosures. The integrated RT cores and tensor cores give it an edge in ray-traced workloads and AI-based tasks, such as DLSS-style upscaling, though the database does not specify any DLSS support. The Vulkan 1.4 support is newer than the LX ULTRA's Vulkan 1.3. Its 12 GB LPDDR5X memory is sufficient for console-class gaming at moderate resolutions. The lack of display outputs means it is not meant for direct monitor connection, but for embedded systems.

The LX ULTRA wins in every raw performance category. Its 24.58 TFLOPS FP32 is 5.7x higher, its 432.0 GB/s bandwidth is 4.2x higher, and its 24 GB VRAM is double. The 192 TMUs and 96 ROPs give it 4x and 6x the texture and pixel throughput, respectively. The 4x DisplayPort 1.4a outputs make it suitable for multi-monitor setups. The PCIe 4.0 x16 interface provides a standard desktop connection. The 6 nm TSMC process is more advanced than the 8 nm Samsung node, though the lack of a die size for the LX ULTRA prevents a density comparison. The LX ULTRA has a higher FP32 per watt ratio (0.1092 TFLOPS/W) than the Switch 2 GPU (0.1075 TFLOPS/W), meaning it is slightly more efficient despite the higher power draw. The LX ULTRA also has a wider memory bus and faster memory clock, which benefits bandwidth-sensitive applications like 4K texturing or compute workloads with large data sets.

In summary, the Switch 2 GPU is the choice for low-power, compact, and AI-capable environments. The LX ULTRA is the choice for maximum performance, high-resolution gaming, and memory-heavy tasks. The data does not support a middle ground; these are two distinct products for distinct use cases.
