Why Didn't AMD Use Jaguar For Microservers?

[sushiwarrior]

OK so clearly OP doesn't know how the search function works, and AMD is using Jaguar in servers. Can we lock this now?

Thread crapping is not allowed. And no, we will not be locking this

What about this part?

So they are stating that ARM A57 cores offer better performance-per-watt than their own x86 Jaguar cores?

probably better densities too...

So its currently just a pure fantasy product? Perhaps one you made up?

That's basically how it turns out, all the time.

No, it will come out, all of them will or have been out:

Bobcot(40-nm) -> Jaguar(28-nm) -> Leopard(20-nm) -> Margay(14-nm)

That's basically how it turns out, all the time.

Heh.

There is reference to a 20NM AMD product called Leopard on this linkedin profile:

There is also a reference to Steamroller Revision A and B too.

I don't understand why AMD is throwing away the SW ecosystem advantage of 64-bit x86 in the server space. Is it because AMD can't afford to shrink Jaguar?

As Johan stated about Jaguar in servers; unless you can use the fpu the perf/power advantage to 32nm atom is not that big.

I guess facebook clusters dont use avx and loads of fpu. Meaning the new Atom will give better perf/power for that market jaguar on 20nm or not. Using a57 is a far more interesting option.

Jaguar is still a nice products for netbooks and cheap notebooks and since its highly synthesized it can easily be ported to 20nm. I just dont really see the purpose of beeing in hurry here, we will see 15w quad core kabini in millions of notbooks, what should 20nm bring that market?

How about tablets?

How about tablets?

But how big is the x86 tablet market?

- secondly, i bet the new Atom is a near perfect fit for the x86 tablets. As i read the tests, AMD needs 16/14nm performance to get this type of fat core into tablets, if that type of 8core jaguar 2, console cpu power is wanted by the market at that time? Dont know but perhaps the gaming driving the tablets and phones will give AMD an advantage for their gpu tech?

In perspective - if we want to know how amd is going to behave: I think AMD, after a petitesse of 30 years of wasting money all the way, except a few years, is in the process of stopping of competing directly with Intel. They dont want to enter with new products for a market if they dont hold a distictive advantage for the segment. Jaguar is perfect for embedded, consoles, netbooks, cheap notebooks and for the extremely small server market where you can use its fpu and/or GPU advantages.

With 20nm a Temash like chip would be much more comfortable in the tablet form factor than it is now. The Temash tablets that have been demoed are a bit thick.

For server workloads and it is not due to Jaguar design but to the x86 instruction set: ARM processors have an advantage over x86 chips in terms of power consumption, cost, and die space
