Crucially, these updates to both Linux and Windows will incur a
performance hit on Intel products. The effects are still being
benchmarked, however we're looking at a ballpark figure of five
to 30 per cent slow down, depending on the task and the
processor model.
This is ugly. Think of the large computing centers, for example
Google's data centers. Suddenly, they will need significantly more
CPU time, and thus electricity (and thus carbon), to get the job done?
It aint just Intel either. The three different CPU issues affect chips
from Intel, AMD, and ARM (no mention anywhere of PowerPC or Apple's own
A-series), and affect virtually all devices sold in the last 15 years -
computers, tablets, smartphones, etc.!
That's gonna be one heck of a clean up bill! :-(
The _only_ processors which will suffer a performance slowdown as a
result of these problems are Intel ones. Spectre affects all chips and
the fix does not affect performance. Meltdown affects processors built
since 1995 by *Intel* and the fix will slow them down up to around
65%.
There's actually THREE issues (at least), despite the fact that the
media is over-hyping just those two.
Very true. However, the ones affecting AMD had little to no chance of
affecting performance from the very beginning whereas the Intel one
was looking to be fairly disastrous. That Microsoft and Apple managed
to keep the performance hit at a bare minimum is a testament to their
ability.
That last line is sure to trigger Peter the Klöwn.
Microsoft simply waited for Apple to fix the issue, then copied them. ;-)
