Oh no, not again...

@Seiya
We will have to wait and perform AmigaOS benchmarks on this thing (which will have faster memory and more Mhz anyway).

What's supplied there its hardly any indication, we have an SSE3 equipped 64bit Xeon 5160 (3Ghz) workstation at the office running XP-64, and this year we also added (among others) a quad core i7 PC, the latter is faster but it's certainly not night and day it's twice as fast in renderings, but on everything else the difference is felt alot less.

Why did I mentioned this? Simply because the core-mark score (per mhz) for the 5160 is 2.4 while the PA6T running on Debian at 1.7Ghz and with slow 400Mhz ram, scores 3.2 (better). On the other hand our Corei7 scores 15.1!!!!!

That's ridiculous, we should be getting a x7 speed increase while we get far less

I don't know what trigger those scores on coremark but let me tell you, there is something wrong.

Don't be so silly. If I said to you that I had a car to offer to sell you next Summer but I can't tell you what engine it'll have in it quite yet, I would not be dishonest. In fact, as long as I told you what engine the car had in it before I asked you to part with any cash I would have been completely transparent with you.

AEON have not started offering these machines for sale yet. The machine is still in development. So, they can keep secret whatever they like until the point at which they offer it for sale and they'll have not been dishonest or even immoral in any shape or form.

Your claim of dishonesty is very silly.

AH.

lets hope there come soon more benchmarks about pa6t to show that it is really a great CPU.

if there come not more benchmarks, that show that its great, then maybe its not great.

because if something is great, it should show that it is great.every new CPU on X86 is lots benchmarked.

Also when look what the people do before, they work on ARM Cores.ARM cores give too not so much performance /MHZ, but use less power.

I dont think they can do the wonder to give G4 G5 Performance /MHZ, before i see a benchmark that show this.

for pa6t there are no confirmed specint or specfp values.

pa6t is great for copyprotection or to avoid hacking of military equipmemt, because it have a encryption in the CPU core.

If i were involved with A-eon I would try to hire Umisef to try to evaluate (find flaws) in the beta boards and Amiga OS 4.1 . Someone who is not so "friendly" can save you problems in the long run. remember the lipservice with problems with the MAI chip on the A1 ?. Most people thought that Bill Buck and co were just being nasty but they were teliing the truth,

When the Freescale P5020 was announced, I thought perhaps they were waiting for that chip to be made public. But the number of PCI-Express lanes doesn't fit I don't think. But perhaps there is another not quite yet announced PPC chip that they are not allowed to talk about until the chip vendor goes public...

If the whole Agnilux/PA Semi thing was what was going on, perhaps the Google buyout threw an unexpected delay into everything.

Why do you have to be so antagonistic about delays? If you really are such a professional, you should be aware that unintended delays do sometimes happen. And it's not always your own fault, but you are affected and delayed because of it. If you've never ever ever been affeced by some unexpected and unwanted delay, then you're either lieing about no delays in your experience, or your lieing about being in a related profession for so long.

As for codenames, "Xenon" sounds better than "Waternoose".

"The processor, internally codenamed "Waternoose" by IBM and XCPU by Microsoft."

Atleast the 65nm version of XCPU has the codename of "Falcon"....

@DAX

It would be interesting to know if there is some physical limitation on nemo that prevents the SOC from running @ 2Ghz.
(perhaps the CPU clock affects serdes lines & SB600 & xena interface)

And I find it funny&strange that they do not use a fan on the SOC. Instead they underclock it to 1,8/1,6/1,2/1/0,8Ghz.

Someone posted a block diagram of xbox ppc cpu. There shows 3 cpu blocks in the picture. Are xbox tri-core or tri-processor?. I think that three cores != three processors.
Somebody knows?

Are we just debating on semantics?

XBox 360's XCPU includes 3 PPE CPUs. Each PPE includes 1 VMX128 unit. PPE is like PowerPC G2 type CPU with high clock rates, long pipeline depth (like Intel Pentium IV Northwood) and VMX unit. The 3 PPEs shares 1.6Ghz L2 cache.

In the terms of AMD's Athlon II X3, you could say Xbox 360’s CPU as IBM PowerPC G2+ X3.

I find now with luck another benchmark value of pa6t.but problem is the pasemi Homepage is as we all know closed and it is a (german) post, so verification is not possible

The thread is a announce of AMCC Titan CPU that do with 2 cores 8000 drysytones.

"""""
http://www.ppcnux.de/?q=node/6888&page=2
Noch ein Vergleichswert:

Laut http://www.pasemi.com/news/pr_2007_02_05a.html bringt es der Pwrficient PA6T-1682M auf 8800 Dhrystones/s (beide Kerne zusammen, wenn ich es richtig verstehe), also 10% besser als der AMCC.
""""""

This text mean that the pa6t do 8800 drystones with his 2 cores.And this is only 10% better as the AMCC Titan.

Some stuff of PA semi home page seems to be here:

@KimmoK

ah thanks for the init link.I add the other letters and here can see what they write about the drystones on their page-

"""""""
http://web.archive.org/web/20070821022655/pasemi.com/news/pr_2007_02_05a.html

Total device power dissipation is 5-13W typical, or 25W worst case. (Worst case has both processors running a thermal-stress program at 2 GHz, and all peripherals active at maximum activity.) This is three times to four times lower power than other processor solutions implemented in 65-nanometer process technology with equivalent peripheral support. At 2 GHz, the 1682M delivers 8,800 Dhrystone MIPS of performance using both PA6T CPUs.
""""""

now you can also compare the drystone with a G4.for a single core pa6t come to 4400 then.

what do a G4 and a G5 ?

@Seiya

The list most be bit out of date,

I was looking for Freescale I know they have a few “ARM” based cpu’s but they were not in the list, as well as the AMCC chips were not there.

Errrr, who says they won't use a fan???? The shown X1000 is only a (Rev 1) prototype, not a production model.

BTW, I am glad you can underclock it, because it makes it much easier for developers to see how their software runs on slower hardware (like Sam440).

When I told people that a 2Ghz Titan could generate 8000 mips they all fired back at me saying "mips" aren't that Hot these days, and that vector units are way more important.
On a link posted abobe I read:

The PA6T's back end can execute the following instruction types in parallel:

2 integer operations
1 floating-point operation
4 vector operations
1 load/store operation

It would seem the PA6T is strong on vector operations, however we are talking "Mips" now?

The fastest PPC i think is the IBM Xeon in the xbox360.

Well no, not even close.

The Power6+ is available at 5GHz from IBM, and is I believe dual core with dual thread per core. The Power7 is 8 core, 4+Ghz, 4 threads per core.

The one in the xbox is a slow chip compared to the last few generations of IBM power chips.

Still limited by front-end's instruction issue.
