I would say the G4 will get increase in speed, but the G5 will wait until Jan, or later depending on how far the G4 can be taken. Although I would like to see a 2GHz PPC in a Mac sooner rather than later.
If motorola does not use Altivec in the G5 a 2GHz processor just wont be same. I may hang on to my G4's for a while.
One thing that will have to be put into the G5 is Altivec. With out that it would just be a off the shelf type processor. Also they should think of putting their 256Bit Architecture to use and bump the bus speed to at least 300Mhz or more. Other wise apple has great computers, many people just dont know it.
Generally speaking, SIMD is teh general term for architecture like AltiVec or SSE2. Specialized areas of the CPU are dedictated to perform a certain type of operation on certain data sets.

If you mean that SIMD is a generic term rather than someone's trademark, yes. It describes things like vector processors that load a series of values and perform the same operation on all of them - whence "single instruction, multiple data." Think of something like a gaussian blur, or compression/encoding/decompression, where every part of a file has an identical operation performed on it. Conventional CPUs, by contrast, generally load one set of data and perform several operations (instructions) on it.
Since SIMD is a different way of treating data with a different purpose than CPUs are conventionally used for, SIMD processors were (and still are) separate, dedicated units (in fact, IBM prefers it this way, which is why they didn't get on the AltiVec bandwagon). The Quadra 840av had a separate SIMD unit on the motherboard.
Motorola, AMD, Intel and even IBM all ship CPUs with SIMD capabilities now: Motorola has AltiVec, AMD has 3dNow!, Intel has SSE2, and I don't know what IBM calls the one they make for Nintendo(?), or the one they're planning for the next generation G3s.

I would be shocked and amazed if it didn't. Frankly, if RISC purists like IBM are moving over to integrated SIMD, I don't know if it will soon be possible to find a desktop or high-end embedded processor that doesn't have something like AltiVec in it. The sorts of things that computers are asked to do now demand onboard SIMD.
<strong>1. G5 or the faster 1.2/1.6 Ghz G4 will be debuted before Aug.

I tend to agree with #3. At my university, the computer store is selling the G4/733 (educational model) and 15" flat panel as a bundle for $1550, for a savings of $277. This deal only applies to the 733 model, but it means one can get the 15" flat panel for less than $300.
It sounds to me like they're trying to get rid of their stock before Tokyo.
<strong>How can you end of file a monitor? wtf ?</strong><hr></blockquote>
sorry, EOL....typo......
I think this rumor makes sense since the 15" LCD monitors are dirt cheap now and the price of the 17" LCD monitor is almost 25% off comparing to the price that when it was in the market. it is plausible for Apple to reduce the price of the current Apple 17" LCD monitor.
It was announced today that there is a shortage of motherglass expected until 2003, this may affect price drops. I don't know how much this will affect Apple since they tend to sign some good long term price deals.

I wish I had the money to use a 15" Apple LCD monitor every time I wanted to signify the end of a file.

I'll bet you an iPod (a 10GB one) that the G5 will have a SIMD that can accept AltiVec-optimized code.

I don't keep up on processor terminology. Whould you mind spelling out SIMD please.

ok?

yeah...because spelling out an acroynm is adequate explanation?
Please, go fantasize about wireless mice.
