The idea of ARM has gone mainstream

We still don't have any usable servers on which I could install Fedora and have it supported for more than 3 releases, but gamers already debate the merits of ARM. The idea of SPEC-per-Watt has completely gone mainstream, like Marxism.

<sage> new uarch? it's about time
<sage> they just can't make x86 as power efficient as arm
<JTFish> What is the point
<JTFish> it's not like ARM will replace x86 in real servers any time soon
<sage> what is "real" servers?
<JTFish> anything that does REAL WORLD shit
<sage> what is "real world"?
<JTFish> serving internet content etc
<JTFish> database servers
<JTFish> I dunno
<JTFish> mass encoding of files
<sage> lots of startups and established companies are already betting on ARM for their cloud server offerings
<sage> database and mass encoding, ok
<sage> what else
<JTFish> are you saying
<JTFish> i'm 2 to 1
<JTFish> for x86
<JTFish> also I should just go full retard and say minecraft servers
<sage> the power savings are big, if they can run part of their operation on ARM and make it financially viable, they will do it

QUICK UPDATE: In the linked article:

The next Intel uArch will be very similar to the approach used by AMD with Zen – perfect balance of power consumption/performance/price – but with a huge news: in order to save physical space (Smaller Die) and to improve the power consumption/performance ratio, Intel will throw away some old SIMD and old hardware remainders.

The 100% backward hardware x86 compatibility will not guaranteed anymore, but could be not a handicap (Some SIMD today are useless, and also we can use emulators or cloud systems). Nowadays a lot of software house have to develop code for ARM and for x86, but ARM is lacking useful SIMD. So, frequently, these software are a watered-down compromise.

Intel will be able to develop a thin and fast x86 uArch, and ICC will be able to optimize the code both for ARM and for x86 as well.

This new uArch will be ready in 2019-2020.

Curious. Well, as long as they don't go full Transmeta on us, it may be fine.
