Those who sit on top of their PA6T stock should take a notice, they can not ask USD1000+ per chip any more.

Well, there's more to it than availability of something else for less. The pa6t is mostly in military stuff. They'd rather build and pay for something known working than redesign and go through whatever military recertifications there are for a new "same" product. The x1000 is just a completely unlikely and weird product all around. And while we can look forward to a new design, and we shouldn't stick to pa6t, the x1000 is not representative of what pa6t actually ended up in since Apple jumped to Intel and then ate PA Semi's engineers.

The P5021 uses the e5500 which has no altivec.

@olegil,

The T2 & T4 series are of interest to me. With the right mix of slots would be a good road to go down for Altivec higher end machines.

Of course everyone knows that Steve Jobs was still worried about the possibility of an Amiga comeback that would kill all of Apple, which is why he bought, then shut down PA Semi and switched to Intel.

Actually, the difference between a T4080 and a T2080 is minimal in practice. The T4 has up to 16 extra serdes'es, but since there is a split in 16 for networking and 16 for non-networking while the T2 has 16 useable for anything, a card that only needs up to 2 GbE ports will have 16 ports for PCIe/SATA in both cases.

Performance wise both are now 1.8GHz, but the T4 was targetted a little higher to begin with.

One (2080) vs two (4080/4160) or three (4240) DDR3 controllers is much more a hassle for board layout than it is a benefit to the user, imho.

So having investigated it, I think they bummed out a little with the T4. It should have been better. As it is, a T2 is plenty fine as the high end for our purposes.

T1 makes for an awesome low-end, btw.

I would say it falls somewhere in the ballpark of the T1. 6 cores at 1.2GHz wouldn't be a lot faster then 4 cores at 1.4GHz. IO wise it has more pins, but hard to know exactly what can be used at the same time. Wouldn't really bother

It have six core 476 processor, the same processor in the WiiU, if i recall well

You brought up slots, which I sort of neglected to mention in my response.

A T2 or a T4 would both be looking at x4+x4+x4+x2 PCIe (two of which can theoretically be PCIe 3, ie 8Gbps, but only one at a time (eh?)). However, your total PCIe performance will NOT be 32+16+16+8=72Gbps per direction (in case anyone else than me wanted that) .

I have the specific throughput numbers for the T4, but not for the T2, so will refrain from speculating on any difference here. This COULD be the biggest difference between the two families, though.

I would give one x4 to graphics and one to a southbridge. As mentioned before either here or in another discussion, I would put the southbridge on a riser card, and connect it with a wire to the main board. From that you then get something like 3 x1 PCIe slots, for more stuff. Plus an argle number of SATA/USB ports, obviously.

@AmigaBlitter

Yes, clocked at 1.2GHz. Vs 1.4 in the T1.

@olegil,

Would be nice if we could get some modern features like Dual graphics slots for crossfire or something but I bet it will be a long time before there is support for it. It would also be nice to have 1 x16 slot for good graphics then range down to a single PCI slot for legacy cards. Like 1x16, 2x8, 1x2 and a PCI.

Chris

@QuikSanz

If what you have on the SoC is x4 8gbps, x4 5gbps, x4 5gbps and x2 5gbps, trying to create a x16 somehow AIN'T going to give you any more bandwidth.

What more than several PCIe ports of appropriate speed and a driver do you need for crossfire/sli?

@AmigaBlitter

The Wii U has a three core G3 derived processor according to hackers,
the processor still has all the instructions found in Gekko, the Nintendo Gamecube CPU.

An program named Devolution allows you to play Gamecube games natively on the Wii U.
Man, its crazy to think that the Gamecube still lives on after thirteen years..

@olegil,

Looks like most are of the 1x16 or 2x8 selectable. I don't really need crossfire but to be able to use it is a plus for others. Just one good fast slot for graphics is good for me the rest can drop down in speed. Prolly a good surround card in the 2nd slot and a few extras just in case.

@Trewq

476fp core is an IBM design too.

@SoC chip example (the competition)

I think these are one of the most advanced intel SOC chips:

UPDATE: some older PowerPC info from morphzone if not on this thread already:

- Next generation PPC core ("NGC" with multithreading, higher single-thread performance, directory snoop filters, low-latency clustered accelerators)
-some info about LS2045P, LS3400P, T3, T4400 (40 virtual cores)

Originally Freescale was planning also single threaded T5 series, but not heard anything about that for a while.
(original "plan")

Some thought: As verisilicon is part of openpower, I hope they will do rev2 of their gaming soc with Power core.

Not really. Had eval server with that one last winter and It already beat E3 Xeons on some tests. And new models coming in Q3.

No new news.

But it seems there is some delays especially with volume shipments of low end T series of chips etc.
Perhaps because of HW bugs that were reported (also) on freescale forums.

There's a processor conference scheduled October 22-23, 2014, perhaps then there will be some news for PowerPC from Freescale...

btw. from game console sales, the weekly HW sales numbers:
PowerPC 125 000. (Wii, WiiU, PS3, xbox360)
AMD 272 000. (PS4, XboxOne)

@KimmoK

IMHO, Freescale should think about joining OpenPOWER and licensing the POWER8 core. They could make a lower-power version for the next gen Txxx chips.

_________________

@WolfToTheMoon

Freescale PowerPC cores have very short pipelines and they have therefore some advantage in telecom. So I doubt Power8 core offers them nothing special.

(freescale has new core in their plans anyway)
