NVIDIA RTX 4500 Ada Generation vs Lisuan Tech LX ULTRA Comparison

The Verdict

The data presents a stark contrast between two workstation-class GPUs. The NVIDIA RTX 4500 Ada Generation is a fully characterized, benchmarked product with an average score of 166,094, placing it in the 97th percentile of all GPUs. The Lisuan Tech LX ULTRA, by contrast, has no recorded benchmark scores, an average benchmark score of zero, and sits in the 50th percentile. For any workload requiring validated compute performance, the RTX 4500 Ada is the only option with measurable results.

The RTX 4500 Ada delivers 39.63 TFLOPS of FP32 compute, while the LX ULTRA provides 24.58 TFLOPS. In FP16, the NVIDIA part offers 39.63 TFLOPS with a 1:1 ratio, whereas the Lisuan Tech part reaches 49.15 TFLOPS but at a 2:1 ratio, indicating a different execution path. The RTX 4500 Ada also leads in texture rate, 619.2 GTexel/s versus 384.0 GTexel/s, and pixel rate, 206.4 GPixel/s versus 192.0 GPixel/s.

The Lisuan Tech LX ULTRA does have advantages in the data. It uses a 6 nm process node versus 5 nm, it has 96 ROPs compared to 80, and it includes a dedicated 16-pin power connector while the RTX 4500 Ada lists none. However, with no benchmark results to validate real-world performance, these specification differences cannot be translated into measurable outcome advantages. The RTX 4500 Ada is the only part with recorded performance data, making it the sole choice for tasks requiring verified results.

Architecture Differences

The NVIDIA RTX 4500 Ada Generation uses the AD103 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It contains 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1 million per square millimeter. The Lisuan Tech LX ULTRA uses the 7G105 chip with the TrueGPU architecture, also fabricated by TSMC but on a 6 nm process. Its transistor count and die size are listed as unknown.

The RTX 4500 Ada integrates 7,680 shading units, 240 texture mapping units, 80 ROPs, 60 RT cores, and 240 tensor cores. The LX ULTRA has 6,144 shading units, 192 TMUs, and 96 ROPs, but its RT core and tensor core counts are not recorded. The NVIDIA architecture provides dedicated hardware acceleration for ray tracing and tensor operations, which the data confirms through the RT and tensor core counts. The Lisuan Tech part does not list these units, leaving its capability in those domains unspecified.

The RTX 4500 Ada lists support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX ULTRA supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, but only Vulkan 1.3. Both parts use PCIe 4.0 x16 interfaces, dual-slot cooling, and provide four DisplayPort 1.4a outputs. The NVIDIA card measures 245 mm in length, 112 mm in height, and occupies dual slots. The Lisuan Tech card is longer at 268 mm, has the same 112 mm height, and is 40 mm wide.

The FP16 compute ratio differs meaningfully. The RTX 4500 Ada lists FP16 at 39.63 TFLOPS with a 1:1 ratio, indicating equal throughput to FP32. The LX ULTRA lists FP16 at 49.15 TFLOPS with a 2:1 ratio, meaning it achieves higher peak FP16 throughput but through a different hardware path. This suggests the Ada architecture prioritizes FP32 performance, while the TrueGPU architecture may handle FP16 with separate hardware units.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two GPUs. The RTX 4500 Ada has two recorded benchmark scores: 160,786 in Geekbench OpenCL and 171,401 in Geekbench Vulkan, producing an average benchmark score of 166,094. The Lisuan Tech LX ULTRA has no recorded benchmark scores and an average score of zero.

The RTX 4500 Ada's nearest rivals provide context for its measured performance. It sits 0.5% above the NVIDIA RTX A5500 (average score 165,217), 0.7% above the AMD Radeon PRO W7800 (average score 164,894), and 2.2% above the NVIDIA A100 PCIe 40 GB (average score 162,504). It trails the AMD Radeon Pro W6900X by 1.5%, which has an average score of 168,574. These deltas are small, indicating the RTX 4500 Ada performs within a narrow band of competitive workstation GPUs.

The LX ULTRA's percentile ranking of 50, combined with zero benchmark scores, places it at the median of all GPUs without any measured data to support performance claims. Its FP32 throughput of 24.58 TFLOPS is 38% lower than the RTX 4500 Ada's 39.63 TFLOPS. Its texture rate of 384.0 GTexel/s is 38% lower than the NVIDIA part's 619.2 GTexel/s. Its pixel rate of 192.0 GPixel/s is 7% lower than 206.4 GPixel/s.

In FP16, the LX ULTRA's 49.15 TFLOPS exceeds the RTX 4500 Ada's 39.63 TFLOPS by 24%. However, this advantage comes at a 2:1 ratio, meaning the FP16 throughput is achieved through a different hardware implementation than the 1:1 ratio of the Ada part. The higher ROP count of 96 versus 80 provides the LX ULTRA with a 20% advantage in raw rasterization output capability, though this does not translate into a measured performance lead in the absence of benchmarks.

The RTX 4500 Ada's 60 RT cores and 240 tensor cores provide dedicated hardware for ray tracing and AI workloads, features the LX ULTRA does not document. The NVIDIA part's 97th percentile ranking across all GPUs indicates its measured performance places it among the top 3% of all recorded GPUs, while the LX ULTRA's 50th percentile with no scores indicates a median position based on specifications alone, not validated results.
