Ran a quick test so that we both have accurate numbers, without MTP* at 10k ctx 27B hovers around 42 ts in llama.cpp, 35B around 135 ts. So not the 8x I assumed, just over 3x, but thats still a big difference.
For the sake of testing I turned MTP off, as that heavily depends on what the generated text is (structured text like code is very often a lot more predictable, therefore bigger boosts) and the quality of the quantization, as drafters learn how to "mimic" the full precision generated tokens, so when you layer the fact that MTP is a 'guesser' of the main model's next token, and quantization affecting what exact token is generated, it'd make comparisons like this needlessly noisy.
