Where Each One Wins

The RTX 4090 D wins in every measured compute category. Its FP32 throughput of 73.54 TFLOPS is three times the LX 7G100's 24.58 TFLOPS. Pixel rate, texture rate, memory bandwidth, and shading unit count all favor the RTX 4090 D by wide margins. The 24 GB memory capacity with 1.01 TB/s bandwidth suits large datasets, while the 114 ray tracing cores and 456 tensor cores provide hardware acceleration for ray-traced workloads and AI inference that the LX 7G100 cannot match, as its core counts are unrecorded.

The LX 7G100 wins on physical footprint and power draw. It is a dual-slot card at 294 mm length, versus the RTX 4090 D's triple-slot 304 mm design. Its 225 W TDP is 200 W lower than the RTX 4090 D's 425 W, and its 550 W suggested PSU is 250 W less demanding. The LX 7G100 also offers four DisplayPort 1.4a outputs versus the RTX 4090 D's single HDMI 2.1 and three DisplayPort 1.4a outputs. Its 6 nm process node is one step larger than the RTX 4090 D's 5 nm node, yet it achieves lower power consumption with fewer shading units.

The LX 7G100's FP16 performance of 49.15 TFLOPS at a 2:1 ratio indicates it processes half-precision workloads at twice the rate of its FP32 throughput. The RTX 4090 D's FP16 matches its FP32 at 73.54 TFLOPS with a 1:1 ratio, meaning the RTX 4090 D still delivers 24.39 TFLOPS more FP16 compute. The LX 7G100's active production status contrasts with the RTX 4090 D's end-of-life status, suggesting ongoing availability for the former.
