The RTX 5080 16GB has about 7% more memory bandwidth (960 vs 900 GB/s). Batch-1 decode tracks bandwidth closely, so a model that fits both cards should decode roughly 7% faster on the RTX 5080 16GB. Both fit the same number of catalog models at Q4/8K (25 of 73; 16 vs 16 GB VRAM). MSRP is $999 for the RTX 5080 16GB vs $8,000 for the V100 16GB PCIe. MSRP is a launch list price, not live retail — Amazon prices move; click through for the current price. Not retail-shoppable: V100 16GB PCIe (datacenter-class; cloud rental is the realistic way to use it). In the Q4/8K head-to-head below (49 shared models), the RTX 5080 16GB posts the higher tok/s in 48 rows vs 1. Methodology.
