I read an article several years ago about the origination of SACD. Sony wanted a way to archive thier music library as master tapes were becoming brittle, and the magnetic dust was coming off of them so that they could only be played one or two more times.
Thier solution was a grain silo sized thing with robotic arms, climate control, redundancy, auto rewriting media with bit rot, etc. It was quite impressive!
I think that Sony also records all new music in this format.
In time, hopefully, all of the above will converge into one cheap chip. There are players no that do DVD Audio and SACD, but they are $1000+
While higher fidelity would be nice, it is not that necessary. Most stereos and speakers are not that high of quality, and most listening areas are not sonically friendly. For example cars, airplanes, offices, living rooms, etc have significant background noise.
What we need is intelligent speakers, with DSP's in them. Then you plug a microphone in to it, and place it at your preferred listening spot. Then the speaker could analyse itself, and your listening area allowing it to compensate for any weaknesses in your setup.
This has the advantage of making all music sources, stereos, and listening rooms sound better WITHOUT having to fork out more cash for new media.
I did. Processor busses and memory speed are different. AGP is going to eat into that processor bus. Also in a SMP scenario, the processors need to talk to each other to keep the memory coherent. Not to mention peripherals doing DMA, etc.
In terms of die size, a rough measure of cost, the PowerPC 970 measures 118 mm2, against 131 mm2 for the Northwood 2.X-GHz Pentium 4. Both the IBM and Intel parts are being made in 130-nanometer CMOS on 300-mm wafers.
This indicates that the price could be competitive in desktops.
Essentially a derivative of the company's Power4 microprocessor, IBM's PowerPC 970 adds 64-bit PowerPC compatibility, an implementation of the Altivec multimedia instruction-set extensions and a fast processor bus supporting up to 16-way symmetric multiprocessing.
I hope they use a memory controller that does at least DDR 333.
This is true, but IBM sells many of these chips for the embedded market, mostly printers and cars.
This is what led to the stink with MOT. Mot wanted Altivec, IBM did not want the increased die size for the useless (to thier market) vector instructions.
This is true, but show me a motherboard for less than $500 with more than 4 DIMM slots. Probably going to need another memory controller, or a bridge chip (with some latency).
Even the 1 giggers are much cheaper, but 4 of them does not present an addressing issue.
Of course the 2 giggers are probably double sided, and you probably can not run three of them anyway..
Many people doing CAD, circuit simulation, or editing large images need more than 4 gigs of ram now. 4 gigs is all you can get with 32 bits. On intel, using evil segments, you can use 36 bit. Win2k Enterprise does this...
Also, do not forget about Moore's Law. CPU's keep getting faster. Problem is hard disks are not. So more RAM for caching will be the solution.
Checking pricewatch I see that 2 gig pc100 dimms are less than $500 each.
This is a constant, dependant on the substance used in the battery. They may get 10 percent more watt hours in this battery.
Peak current should be better, due to larger surface area of the anode/cathode.
Lithium Polymer batteries have a higher energy density BTW.

I do not need new hardware, or need to buy new copies of all my music.
I would like to be able to buy compilation disks with ALL of a groups albums on it, at CD quality, though..
Hey, come on. Read the article you linked to!

Way to go IBM!

They run more PowerPC chip fabs than Motorola.

This will not be the case for 64 bit chips.

I will take price/performance any day.
Getting the volume up is going to be difficult for IBM..
