Difficult to say, no access to Power7 hardware, but from the _very_ few docs out there that I could find, it looks like a mix of Cell SPU and AltiVec. Some instructions are the same, others -esp the double fp or the decimal fp support- have no Altivec equivalents. No idea how it performs really. It probably is quite powerful, but there are virtually no benchmarks out there, IBM sure does a crap job of promoting its technologies.

Update: this is the only doc I found with actual specs/performance info for VSX.

Zylessa, trains and bicycles, man that's so European! I don't drive a truck or and SUV, but train service in my State is extremely limited (blame the US government for short sighted transportation policies) and a bicycle trip to work (for me) would be 80 miles round trip.

And I think I could get used to a netbook, even with a small display and keyboard, if the screen resolution was better (say 1024X768 or at least 800X600) and there was more processing power (you're right 300 to 400 Mhz doesn't cut it these days).

Andreas' minimum works, but again I'll agree with you that a QorlQ processor would be better. And it is a shame that the e600 core is EOL'd. I spent a lot of time studying apps for the 86xx processors.

Still, small Apple G4 notebooks start with a 12" screens, so that's fairly compact (not quite a netbook, but not stupid sized like many laptops on the US market). We should eventually have support for those.

And I'm glad a few people here have noticed to increase in PPC development. A consumer PA Semi based motherboard, AM titan based processors, the new e5500 64bit core - all welcome developments.

Hopefully, I'll still be able to use MorphOS on fairly decent hardware for some time to come.

Offtopic perhaps, but, IIRC, AMD owns xenon production lines nowdays (the Power chip of xbox 360).

That I didn't know, but by AMD you now mean Global Foundries don't you (since AMD has spun off production facilities).

And don't worry about Andreas' comment, he knows perfectly well that none of the three companies I mentioned produce PPCs. However, AMD and Intel may actually be the first to introduce processors with decent on die GPUs (but it hasn't happened yet, all current processors offering this feature have horrible GPU performance).

>> ATI/AMD do Power Architecture CPUs?

> IIRC, AMD owns xenon production lines nowdays

With the merger of Chartered into GlobalFoundries last year AMD became *minority* stockholder of the Xenon production business (ATIC being the majority one).
Anyway, with "do" I actually meant "develop", not "manufacture". A chip being manufactured by GlobalFoundries doesn't make it a GlobalFoundries chip, the same way it didn't make it a Chartered chip before :-)

Then you seem to have missed the actual question: "Or is it that his phrase ends up forty years later that it starts?", where the answer would simply be: Yes, it does (with the small correction that it's rather twenty years, not forty) :-)

Thanks for information. My main question would be if VSX is backwards compatible to VMX/AltiVec by itself or if POWER7 supports both by having both implemented separately. Or similarily put: Does a CPU implementing VSX automatically support VMX/AltiVec, i.e. is VSX a strict superset?

I think it would be pointless for AMD and Intel to "do" anything other than what they're doing right now.
Currently, they're providing virtually all processors used in personal computers (unless you want to include iPad and other compact devices in with PCs).
While some of use seem to be worried about ARM, X86 is the real competitor. Upgraded constantly, originating with a small company building calculator processors, and very luckily picked for IBM first off the shelf consumer oriented computer.
This unlikely architecture has matured to dominate the market.
Would that it weren't true, but AMD and Intel have no reason to "do" anything else.

7" netbooks easily have been doing at least 1024x600 for years, even PPC based ones:

I guess you just got confused by KimmoK answering to an April comment of mine ;-)

Quote:

Yes, that's true (and I probably should have left out the 800x600 spec), but 1024x600 requires more vertical scrolling than I want to do.

Sure? When do you think that the market split between Intel 32 and 64 bit CPUs will turn around? I mean, every computer I see over here is 32 bit, perhaps there's a couple 64 bit, running boring 32 bit software. Is that a "norm"?

Computers grew to double bitness, and yet the world is exactly the same...

All this talk about new PowerPC processots... Has anyone a rough idea about how much building a new PowerPC based computer would cost? It seems everyone and his dog are cooking ARM based 'puters nowadays, why the hell does it have to be so hard with our favourite CPU? Why doesn't freescale play the Beagleboard game? No Andreas, I don't think those "tower" development boards are the same.

Where's bPlan, by the way? Gerald and Thomas got boring jobs? Or became millionaires and live in Bahamas, drinking caipirinhas? Pun intended, for those long time amigans.

Quote:

That's a sweeeeet PowerPC CPU! I was told that, in order to have terrific graphics output, it has the GPU "wired backwards", giving it priority over other general I/O lines. A quick jump to wikipedia would make me learn a lot, but I feel too amigan today.

Quote:

Andreas asking questions? Now the world has turned over Perhaps I should start believing about 64 bit processors being everywhere...

Quote:

You are very right. That also explains how boring this little world of computers became amny years ago. Have you being doing something positively different in your computers for the last ten years?

Quote:

I don't know, perhaps it depends on the environment, for me here, the norm is 64-bit, as I don't really know anyone with a 32-bit PC anymore, unless it is an old laptop, but then again most of my friends are geeks :)

Quote:

It's not easy, The beagleboard was a terrific idea, and this is what I attempted to do with the 8610 board -which is not dead yet, there are some ideas to revive it- and which would be a good ppc alternative, even if the X1000 is released and even if the 8610 is EOL'd.

To me (without bothering to read down into details) it seems that xbox 360 has similar architecture as the xbox1, where the GPU does the memory controlling and CPU get's only what is left over from the GPU.
Like classic Amigas with only Chip RAM.

PPC SOC designs (440ep, 460ex, PA6T) have own memory controllers and they therefore should perform slightly better than chips with external controllers.

I forgot to answer that yesterday:

jcmarcos wrote something interesting regarding Xenon 1.5 weeks ago:

"The new version, jsut on sale now, has a new chip with the CPU, the GPU (!) and the RAM (!!!) all stacked in the same component!"
https://morph.zone/modules/newbb_plus/viewtopic.php?topic_id=7186&forum=11&start=18

Wikipedia:

"Introduced in the Xbox 360 S was the XCGPU where Microsoft have integrated the Xenon CPU, the Xenos GPU and eDRAM in the same package."
http://en.wikipedia.org/wiki/Xenon_(processor)#XCGPU

"...the XCGPU, an integrated CPU/GPU/eDRAM chip using a 45 nm fabrication process."
http://en.wikipedia.org/wiki/Xbox_360#Xbox_360_S

Unfortunately, that chip is only available for Microsoft.

What part of it? Hardware development? Firmware development? Hardware production?

I don't think so (regarding the 'millionaires' part):

I consider feanor to be an authority when it comes to SIMD computing. So it's quite naturally for me to ask him on that.

Carda's personal insolvency filing in October 2008, yes.

Read further down. It mentions Carda as well. Kind of side job maybe? ;-)

Quote:

Thanks Andreas, though I am hardly an authority on the subject, I just like the stuff, and I enjoy SIMD algorithm optimizations immensely. Not to mention, that no matter how much I read, I always end up thinking that I know nothing and have to read more. If I was an authority, I could perhaps influence Freescale to revive AltiVec and or enhance it -I did sent some email To Freescale with suggestions on AltiVec 2, a few years ago, didn't really get anything more than "thanks we'll look into it". :)

Aha, thanks. I agree with you. So here is where Gerald was last seen in the wild:

Hardware development is mostly done by Pegatron -with the cooperation of bPlan-, and production is done solely by Pegatron but bPlan are very close to finishing Aura development on the EfikaMX, thus providing an high level abstraction to the devices/drivers of the device in an OS-agnostic way. Of course, an appropriate Linux kernel is also developed at the same time.

Quote:

Are you sure of any of this information, Andreas? At 65nm we were dealing with separate components. I haven't seen a tear-down of the newest XBOX360, but one chip would combine three different components.
Since the system has to operate the same as older XBOX360s this can't offer any architectural advantages, only lower cost of production.

That doesn't really strike me as an advantage to the user (unless Microsoft wants to pass on some of the savings). Its a little like Intel giving the latest Atoms an on die memory controller, but not changing the design to take advantage of it being on-die. There's no performance increase.

In a situation like that, I'd rather have separate components so I don't complicate or limit upgrade ability.

Quote:

Thanks for the clarification Konstantinos. So, what Genesi/bPlan/Pegatron are doing is making a new computer and custom operating system. Well, almost... But in many regards, it is. Once done, it's all a matter of convincing the world to write kernels for Aura.

The product is almost ready. Hey, I swear I red the word "August" there a moment ago...
