Can I run llama3.1 70b with rtx4090+64g ddr5 ram?

At what rate per second are tokens generated?

This is not an issue, it is general question.
As far as I know, ktransformers speeds up only MoE models, and llama3.1 70b is dense model (no routing/expert layers).
The answer to your question depends on your model quantization level, motherboard, RAM used and CPU.

KTransformers does not offer as significant a performance improvement over llama.cpp on dense model as MOE models do, but it still performs well. You can try writing a YAML file yourself to place the most computationally intensive tasks on the GPU, while the remaining tasks can be completed on the CPU. As long as the DRAM can fully accommodate your GGUF file, KTransformers will be able to run.
