The feature was quietly removed through a firmware update on some non-PRO Ryzen CPUs.
Removing features from firmware is a real dick move.
Luckily that guy noticed soon enough
Yea, but what about next time?
It should be illegal to cripple the things that we buy after the fact. In any way.
From what I read this is somewhat a gray area - AMD never stated that non pro CPUs support it, even though they do and they should. Anyway, it was a dick move.
If you don’t want people to have it, ship without it, though.
Yeah, who knows the reason behind it. Perhaps using same design to lower costs and then they didn’t disable it or something.
And that shouldn’t be allowed.
if that was a hard law, many of the various execution prediction exploit prevention fixes couldn’t have happened, as those fixes technically cripple performance…
I think there is a meaningful difference in this case.
It’s an ATTACK VECTOR.
Without any comment from AMD, it appeared as though the company disabled TSME through firmware on its consumer parts in order to differentiate its PRO lineup.
