I think it's best to say it the way they did. It's one thing to be faster per dollar but it's another thing for to win on performance as well.

From single core to same number of cores to having more cores the 7742 wins in each case and still comes out on top. That's far more amazing than being 5x cheaper. Everyone has known Intel has charged an outrageous premium for a long time but it was also the best so people dealt with it.

Exactly, especially since high margins on those is a defining characteristic of intel. They can match on price if they kill their margin. Matching on performance or power usage ? That’s where their problem is.

Meanwhile amd is making sure to be low priced yet ahead for as long as possible / as many processor gen as possible to create themselves a stable market share, not just the people who buy whatever is best each day, but those that like stability and uniformity and wouldn’t go with zen but now that zen+ and zen2 confirmed it they just might be tempted

The single core performance is remarkable given that Intel has always been very strong there.

How is Linux compatibility in case of AMD these days? Intel is really good, if we ignore the need for blobs for their wireless cards. Everything just works, and it is energy efficient.

You install linux on an AMD system and it runs. Its been that way for a decade. If you buy an AMD GPU and choose a wireless card with care then there really isn't anything to think about when using linux except maybe needing a firmware blob. AMD is one of the better vendors for linux compatibility. CPU, GPU, whatever. All has first class open source support.

It isn't fun like the good old days when things went wrong and people had to learn about the internals of the system to make things run, fighting the hardware every step of the way. Kids these days will have no opportunity to learn how all this stuff hangs togther. It could be worse than the time everyone stopped having to learn assembly. We live in an age of moral decay.

Ohh I wish. Ready my reply to parent comment.

I can only speak for the first gen zen. There's a bug with most motherboards that cause a hard lockup every day or so. Changing the power state fixes the problem with an updated bios but disables boost. Thread: https://bugzilla.kernel.org/show_bug.cgi?id=196683

Amd kept leaping ahead in single core while intel finally got their security mitigations in place. Although intel was ahead against zen+, it was not by as much as you imagine since a lot of the intels where tested with mitigation’s partially off by then (and then of course there is intel insistence on reviews being done with smt off which is cute since amd performs better on it too)

I had to add kernel parameters in the installer and bootloader for the computer to install and boot.

Otherwise it doesn't even boot. Ryzen 5.

An upgrade from kernel 4.x to 5.x only changed the required parameters, it still locks up on boot with no extra parameters.
