Discussion Intel Binary Optimization Tool thread

[inquiss]

So using the GPU driver analogy, if a GPU driver makes a GPU look better in a gaming benchmark, is that bad?

Again, this is not my wheelhouse whatsoever, so if the analogy of a GPU driver is not anywhere near representative, then I stand corrected but would like to understand how IBOT is different.

This is a driver that only works to improve framerates for the benchmark portion of the game but then doesn't boost performance when you play the actual game.

Yikes, then that's bad. Deceptive, even.

In real world apps, not unfair. It’s good.

In benchmarks, bad

Well except for Geekbench iBOT is just for games so real world apps

Are you sure though cause than it's straight up cheating.

Like the GB developer showed, Intel executed an extra 17 billion AVX2 instructions via iBOT. If AMD executed those too, then Intel wouldn't look as fast.

Just waiting for the LOL moment when someone cracks iBOT and makes it work on AMD too.

Possibly an outgrowth of that Intel project. But it seems to be making it more difficult to add general optimizations because it doesn't disassemble like BOLT.

^^^ That's a HUGE repo!

With a major twist: it doesn't only change code layout, it also "recompiles" some of the functions.
