A design technique called utreexo allows you to validate essentially every single transaction in the entire history in full parallelism. With an infinite number of cores, you could in theory validate the entire bitcoin blockchain in under a second. That said, you need to do billions of cryptographic operations still, and you need to actually posses the full blockchain. 100k tps+ is not really reasonable on modern consumer hardware, and even getting to 100 requires a lot more engineering than has currently been completed.
