And there wouldn't be enough smart people. These lithography machines are completely wild: the part that fails the most spits out a tiny droplet of molten tin. That's hit with a laser, and the excited electrons emit what's c

Hits forehead for forgetting to check SemiWiki. But note that since then Global Foundries has abandoned for now offering this general node, 7nm as they name it, 10nm as Intel does. But isn't the whole die exposed and otherwise process

It's a good analogy as long as Intel was the first to experience the end of Dennard scaling ( https://en.wikipedia.org/wiki/Dennard_scaling ) because their fab lines were ahead of the rest of the industry's. A

KBR = Kaby Lake Refresh. Interesting, in that Intel's "10nm" node is said to be more power efficient than their "14nm" node, in this case, per AnandTech ( https://www.anandtech.com/show/11738&#x

That's interesting, and relevant in that the NexGen team was joined by DEC Alpha people to do the K7, but the K6 is not AMD's first out-of-order speculative execution x86 design, per Wikipedia the K5 was an internal project that &

The current set of vulnerabilities target Intel specific microarchitectural features, like the first version of Foreshadow/L1TF targeted the SGX enclave, which by definition isn't in other company's CPUs. Given that AMD is fu

I've heard entirely the opposite, that having a close relationship between chip designers and fabricators allows for higher performance designs. I don't know of anyone who interpreted AMD selling off its foundries as anything oth

These vulnerabilities can jump process address space boundaries. It's a lot harder but can be done, look at the original Spectre paper: https://spectreattack.com/spectre.pdf

Sounds like it. None of the brand names you mention were known in my part of the US at the time, and I don't even recognize any of them today except for Gundig. For TVs, Japan very conveniently for the US shares the same NSTC standard

Red Hat released info about z/OS mainframes, they're also vulnerable to Meltdown as well as Spectre. ARM also has one new design that's vulnerable to Meltdown, and everyone has Spectre vulnerable designs.
