Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two cards. The only recorded benchmark for the RTX 5090 D V2 is 3DMark Steel Nomad DX12, with a score of 16,504. This score places it near four rivals in the database: the NVIDIA T400 at 16,508 (0% delta), the AMD Radeon PRO W7500 at 16,415 (0.5% delta), the NVIDIA RTX PRO 6000 Blackwell at 16,408 (0.6% delta), and the AMD Radeon RX 5700 XT at 16,361 (0.9% delta). The LX ULTRA has no recorded benchmarks and no nearest rivals.

Without head-to-head data, the comparison relies on architectural specifications. The RTX 5090 D V2 delivers 104.8 TFLOPS of FP32 performance, which is roughly 4.3 times the LX ULTRA's 24.58 TFLOPS based on the figures in the database. In FP16, the NVIDIA card achieves 104.8 TFLOPS with a 1:1 ratio, while the LX ULTRA achieves 49.15 TFLOPS with a 2:1 ratio. Pixel rate favors the NVIDIA card at 423.6 GPixel/s versus 192.0 GPixel/s. Texture rate favors the NVIDIA card at 1,636.8 GTexel/s versus 384.0 GTexel/s.

The memory bandwidth advantage is significant. The RTX 5090 D V2's 1.34 TB/s is more than three times the LX ULTRA's 432.0 GB/s. This bandwidth difference will affect memory-intensive workloads such as high-resolution texture streaming and large dataset processing.
