New High Performance, x86 Compatible Microprocessors from Centaur / VIA

[R-T-B]

Very likely. It's a little more fine-grained than just lumping the Atom in with one series or another, but at their core, Atom had a lot more in common with the Pentium3/PentiumM than with any of the 486 line.
(BTW, thanks for pointing that out, I read up on more detail aspects of the Atom line and learned a few more things I didn't know before.)

Speculative execution is a huge core design fundemental decision, not sure I can agree with that but it's down to perspective I suppose.

The CPUs were crap

Yes, they were.

Speculative execution is a huge core design fundemental decision, not sure I can agree with that but it's down to perspective I suppose.

Speculative execution is also very power hungry, which is why Intel cut it from the feature set. Atom was intended to be very power efficient, so power intensive features were removed leaving only essential functionality. However, what remained was still directly derived from Pentium M. From there Atom evolved in directions that followed the idea's of power efficiency. As each iteration was produced the line became more effective. I personally think that Intel did well to make a power efficient CPU that also performed in a competent way...

Yes, they were.

...despite what many may think. I still have two Atom powered devices, both still running strong and both still performing well.

I was talking about in terms of being similar, not in terms of whether or not it was a good design decision (it was).

i miss cyrix.

I don't, it was a HOT! pile of SHIT, days after getting the 150+ i wished i had saved a little more for AMD's chip.

As for this thread i will believe it when they proove it and not before

A large increase in the performance of the new microarchitecture.
ZX-A / ZX-C / KX-5000 / KX-6000 = small cores
KX-7000 = BIG cores

First impression - Rise of the small cores

Cinebench R23 CPU (Multi Core)
● VIA QuadCore C4650 2.0GHz (28nm, 4C/4T, 2MB L2 cache): 733 pts (34,49%)
● Zhaoxin KaiXian KX-U6580 2.5GHz (16nm, 8C/8T, 8MB L2 cache), : 2 125 pts (+189,90%)


And here is my older game results with VIA QuadCore compare with Zhaoxin OctaCore

World of Tanks enCORE - ULTRA
● VIA QuadCore C4650 2.0GHz (28nm, 4C/4T, 2MB L2 cache) + NVIDIA GeForce GTX1050Ti 4GB OC: 5 648 (50,10%)
● Zhaoxin KaiXian KX-U6580 2.5GHz (16nm, 8C/8T, 8MB L2 cache) + NVIDIA GeForce GTX1050Ti 4GB OC: 11 273 (+99,59%)

World of Tanks enCORE - MEDIUM
● VIA QuadCore C4650 2.0GHz (28nm, 4C/4T, 2MB L2 cache) + NVIDIA GeForce GTX1050Ti 4GB OC: 8 159 (30,56%)
● Zhaoxin KaiXian KX-U6580 2.5GHz (16nm, 8C/8T, 8MB L2 cache) + NVIDIA GeForce GTX1050Ti 4GB OC: 26 702 (+227,27%)
