NVIDIA RTX 4000 Ada Generation vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data shows a clear imbalance in benchmark coverage between these two cards. The NVIDIA RTX 4000 Ada Generation has two recorded benchmark scores, while the Lisuan Tech LX ULTRA has no recorded benchmark scores in the database. This makes a direct numerical comparison impossible for most workloads, but the available data still provides useful context.

The RTX 4000 Ada Generation scores 146,593 in Geekbench OpenCL and 123,842 in Geekbench Vulkan. Its average benchmark score across all recorded tests is 135,218. This places it in the 95th percentile among all GPUs in the database. The Lisuan Tech LX ULTRA has an average benchmark score of 0 and sits in the 50th percentile, which reflects the absence of recorded results rather than actual performance.

For context, the RTX 4000 Ada Generation's nearest rivals in the database are the NVIDIA A10M with an average score of 135,230 and a delta of 0 percent, the AMD Radeon PRO W6800 at 135,396 with a delta of -0.1 percent, the AMD Radeon Pro W6800X Duo at 135,774 with a delta of -0.4 percent, and the AMD Radeon PRO V620 at 136,472 with a delta of -0.9 percent. These deltas indicate that the RTX 4000 Ada Generation is essentially tied with these professional workstation cards, trailing the fastest of them by less than 1 percent. The data shows a tightly clustered performance band among these GPUs.

Without any recorded benchmarks for the LX ULTRA, the database cannot confirm its real-world performance relative to the RTX 4000 Ada Generation. The specification sheet suggests competitive compute capabilities, but benchmark results are the only reliable measure, and none exist for this card.

Architecture Differences

The two cards come from fundamentally different design lineages. The NVIDIA RTX 4000 Ada Generation uses the AD104 chip built on the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The Lisuan Tech LX ULTRA uses the 7G105 chip with the TrueGPU architecture, built on a 6 nm process, also at TSMC. Its transistor count and die size are not recorded in the database, so density figures cannot be compared.

The RTX 4000 Ada Generation belongs to the Workstation Ada generation, with the predecessor listed as Workstation Ampere and the successor as Blackwell PRO W. The LX ULTRA belongs to the 7G100 generation, with no predecessor or successor listed. The NVIDIA card was released on August 8, 2023, while the LX ULTRA has a release date of March 16, 2026.

Both cards use GDDR6 memory, but capacities and bus widths differ. The RTX 4000 Ada Generation has 20 GB on a 160-bit bus, delivering 360.0 GB/s of bandwidth. The LX ULTRA has 24 GB on a 192-bit bus, delivering 432.0 GB/s. Both run memory at 2250 MHz with 18 Gbps effective speed.

Compute resources show both similarities and divergences. Both cards have 6144 shading units and 192 texture mapping units. The RTX 4000 Ada Generation has 64 raster output units, while the LX ULTRA has 96. The NVIDIA card includes 48 ray tracing cores and 192 tensor cores. The LX ULTRA has no recorded ray tracing or tensor core counts, which means its ray tracing and AI acceleration capabilities cannot be quantified from the data.

Pixel and texture rates reflect these differences. The RTX 4000 Ada Generation achieves 139.2 GPixel/s and 417.6 GTexel/s. The LX ULTRA reaches 192.0 GPixel/s and 384.0 GTexel/s. The LX ULTRA has a 37.9 percent advantage in pixel fill rate, while the RTX 4000 Ada Generation has an 8.75 percent advantage in texture fill rate.

Floating point performance differs in structure. The RTX 4000 Ada Generation delivers 26.73 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The LX ULTRA delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16, indicating a 2:1 ratio. The RTX 4000 Ada Generation is 8.7 percent ahead in FP32, while the LX ULTRA is 83.9 percent ahead in FP16.

Power requirements diverge substantially. The RTX 4000 Ada Generation has a 130 W TDP with a suggested 300 W power supply. The LX ULTRA has a 225 W TDP with a suggested 550 W power supply. The LX ULTRA consumes 73.1 percent more power according to TDP figures. The NVIDIA card is single-slot, while the LX ULTRA is dual-slot. Both use a single 16-pin power connector and both use PCIe 4.0 x16.

Physical dimensions differ as well. The RTX 4000 Ada Generation measures 245 mm in length and 112 mm in height. The LX ULTRA measures 268 mm in length, 112 mm in height, and 40 mm in width. The LX ULTRA is 23 mm longer but the same height, with its width being the added dimension for the dual-slot cooler.

API support shows minor differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4000 Ada Generation supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. Both have four DisplayPort 1.4a outputs.

The Verdict

The data supports different conclusions for different users. For those who need verified performance, the RTX 4000 Ada Generation is the only card with recorded benchmark results. It sits in the 95th percentile of all GPUs and matches the performance of established workstation cards like the NVIDIA A10M and AMD Radeon PRO W6800, all within 1 percent of each other. This is a proven quantity.

For those who prioritize raw memory capacity and FP16 throughput, the LX ULTRA has a clear specification advantage. Its 24 GB frame buffer versus 20 GB, its 432.0 GB/s bandwidth versus 360.0 GB/s, and its 49.15 TFLOPS FP16 versus 26.73 TFLOPS are all recorded facts. But the absence of any benchmark scores means the database cannot confirm how these specifications translate into actual application performance.

For power-sensitive workstation builds, the RTX 4000 Ada Generation is the clear choice. Its 130 W TDP and 300 W suggested power supply are substantially lower than the LX ULTRA's 225 W TDP and 550 W suggested power supply. The single-slot form factor also makes it easier to fit into dense systems.

For users who need ray tracing or tensor core acceleration, the RTX 4000 Ada Generation has documented hardware support with 48 ray tracing cores and 192 tensor cores. The LX ULTRA has no recorded ray tracing or tensor core counts, so its capabilities in these areas are unknown.

Where Each One Wins

The NVIDIA RTX 4000 Ada Generation wins in verified performance, power efficiency, and compactness. Its benchmark scores confirm it operates at the 95th percentile of all GPUs, matching the performance of established workstation cards. Its 130 W TDP is 73.1 percent lower than the LX ULTRA's 225 W TDP, and its 300 W suggested power supply is 45.5 percent lower than the LX ULTRA's 550 W suggestion. The single-slot design and 245 mm length make it suitable for space-constrained chassis. Its 26.73 TFLOPS FP32 is 8.7 percent ahead of the LX ULTRA, which matters for workloads that rely on single-precision math. Its 417.6 GTexel/s texture rate is 8.75 percent ahead, benefiting texture-heavy rendering. It also has documented ray tracing cores (48) and tensor cores (192), which the LX ULTRA lacks in the recorded data. Vulkan 1.4 support is one revision newer than the LX ULTRA's Vulkan 1.3.

The Lisuan Tech LX ULTRA wins on paper in memory capacity, memory bandwidth, pixel fill rate, and FP16 throughput. Its 24 GB frame buffer is 20 percent larger than the RTX 4000 Ada Generation's 20 GB. Its 432.0 GB/s bandwidth is 20 percent higher than 360.0 GB/s. Its 192.0 GPixel/s pixel rate is 37.9 percent ahead of 139.2 GPixel/s, which benefits rasterization-heavy workloads. Its 49.15 TFLOPS FP16 is 83.9 percent ahead, which can accelerate mixed-precision compute if the software supports it. Its 96 raster output units versus 64 provides the hardware basis for that pixel rate advantage. The LX ULTRA also has a wider 192-bit memory bus versus 160-bit, supporting its higher bandwidth.

Neither card has a recorded advantage in the other's areas. The RTX 4000 Ada Generation has no recorded wins in memory capacity or bandwidth. The LX ULTRA has no recorded wins in FP32, texture rate, power efficiency, or any benchmark score, because no benchmark scores exist for it.
