Titan X Pascal 12GB vs V100 16GB PCIe for Local LLMs
The V100 16GB PCIe has about 88% more memory bandwidth (900 vs 480 GB/s). Batch-1 decode tracks bandwidth closely, so a model that fits both cards should decode roughly 88% faster on the V100 16GB PCIe. The V100 16GB PCIe fits more of the catalog at Q4/8K — 25 vs 21 of 73 models (16 vs 12 GB VRAM). Largest model that fits the V100 16GB PCIe but not the Titan X Pascal 12GB: gemma-4-26B-A4B-it (25.2B). MSRP is $1,200 for the Titan X Pascal 12GB 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 (46 shared models), the V100 16GB PCIe posts the higher tok/s in 46 rows vs 0. Methodology.
