Well if they didn't change the socket every year... Realistically though, they might be able to do it for cpu's that aren't soldered on (think just about every laptop) made in the last year or two, but would they really fab new versions of 10 year old cores? Its not like many of those lines are even running anymore, so they would basically have to redesign/layout and reverify everything. Probably easier/cheaper just…

Or give a price break on future hardware. The fix is turning out to be incredibly expensive for ordinary users, virtualization vendors, hardware vendors, OS providers, cloud providers, etc. This incident demonstrates why you really don't want catastrophic bugs in the CPU. The fact that the hardware vendors missed this one makes you wonder what else is out there.

>Or give a price break on future hardware

feels like this would happen:

>intel agrees to give consumers a $30 price break in response to meltdown/spectre

>in other news, intel raises the prices of next generation CPUs by $30

They consider a bug that renders the OS unable to boot a "low" urgency!?!

The last time I used Ubuntu, they hadn't yet realized what vertical display synchronization is, and nobody had explained to them that you don't do your rendering on the framebuffer you're currently scanning out. So an occasional boot of the recovery kernel truly vanishes behind the plain broken display they expect you to put up with.

Sorry fam - security issues are more important ¯\_(ツ)_/¯

it's the fault of Intel, why don't they recall all the CPU? just like vehicle company

Is this endangering the life of anyone? A car manufacturer doesn't do a recall if personal safety isn't at risk.

They will often refuse to do a recall even if personal safety is at risk. The real quantifier is how much financial damage the auto company will endure in the event they do or do not do a recall

They really should. The problem is this nearly every single processor Intel shipped for a decade so Intel doesn't have the cash flow to RMA that many replacements. They're going to fight tooth and nail to avoid this.

Wait if a court forces Intel to replace processors with a safe one does that mean I get new macbook?

Eh, sometimes they do for the sake of brand preservation. If personal safety is at risk they will do a recall, either voluntary or mandated by the NHTSA.

Doesn't this affect all of their CPUs going a long way back? And how do you recall embedded or laptop CPUs, which are often soldered in-place? A recall would be great, but there's no way they'd be able to do it. Vehicle recalls are a bit different because they impact physical safety. Digital safety doesn't get the same priority.

even if it affects all speculative CPUs, if this happened in the car world, all the cars would be recalled. Not saying that is practical in computer world...just continuing with the analogy.

Spectre/Meltdown is a wakeup call for many things, one of them probably being for computer manufacturers to not solder the CPU to the Motherboard and for the x86 world to stick with a standard socket, to facilitate replacing parts.

How about they go into bankruptcy with most of the world’s computer users as their creditors? Maybe not, but it’s terrifying that you can avoid responsibility by fucking up on a larger scale than most.

I'm sure Intel has a liability insurance policy that covers this type of thing.
