> it's the reason the closed amd drivers are so much faster than the open mesa ones.

On the contrary, Mesa is faster than their blob. AMD themselves are working on replacing blob with Mesa in the long term.

Firmware doesn't offer any acceleration advantages, it's used for different purposes.

yeah... I don't know what numbers you're looking at but that's not true in the general case. and this isn't firmware, it's microcode. firmware is already on the chip. microcode is used so the os can take advantage of chip specific features, like security patches or even acceleration.

Do you have actual benchmarks which show the closed source OpenGL driver significantly faster than the open source one? In Phoronix benchmarks I've seen, the open source driver beats the closed source one by a large margin.

That's years ago and is outdated. Today Mesa beats the blob point blank, thanks to AMD themselves working on optimizing radeonsi.

A lot has changed in the last two years. Nowadays you have an occasional game that is faster on the blob driver, but most are faster under Mesa, often significantly so.

They clearly said in the presentation, that microcode is a form of CPU firmware.
