In terms of _hardware_, no. If you are thinking about graphics card-like
hardware, then the answer is no. However, different architectures, e.g.
64-bit and reduced instruction set, can affect speed considerably.

Yes, it is much slower, but that's the inevitable disadvantage of using
high-level programming languages. It's a trade-off between abstraction,
i.e. ease of development and the resulting speed.
