800Mhz A1G3XE the best choice than the 800Mhz A1G4XE?

[Helgis75]

Thought this thread would be the most interesting...It may seem that the A1G3XE is the only one having a faster CPU than originally planned...

Would this mean that the 800Mhz A1G3XE would be the best choice, as opposed to the 800Mhz A1G4XE?

If this speed-similarity is the case, then i feel i should really consider the 800Mhz A1G3XE, because of the full 512KB L2-cache, and the CPU is from IBM. The 750FX G3 CPU is just 1 year old, being produced last year!

Anyone is free to send feedback to this thread, but it has to be related excatly to the A1G3XE vs A1G4XE..Do NOT write other things that don't have anything to do with this thread! Very important, as i want clear answers to all my questions...

Hmmm, what shall I have for lunch? Suggestions anyone? :-)

Get the G4.  It's very very rare for a newer generation processor to be slower than the previous one, and only Intel has a habit of it :-)

@mikeymike
Exactly!
I miss the Tulatins!!!  :boohoo:  :boohoo:  :boohoo:

I have ordered an XE-G4 too. I'm not too troubled about
performance. At the time when we get apps that really push
to the limit of the processor, we will either have new
hardware already or the whole platform has gone down the
drain (again) and we are left to depend on third-party
software to keep us afloat, in which case the question is
mostly academic (but at which point that Altivec unit might
be nice to have).
 
I'm presently more worried on availability of the G4 - i.e
later deliveries of the G4 than the G3. If that's the case I'll
switch over to an G3. But as long as I can get hold of a G4
I'll go for that.

I think the speed difference is small overall.

Bandwidth hungry apps like specmark and 68k emulator would benefit from the larger cache of the 750FX.  But I would expect that G4 would do things like DVD playing on lower CPU overhead with the help of altivec instructions. I'm sure Moovid vill be updated pretty soon affter AOS4 release to  take advantage of Altivec.

(I buy the G4 model after AOS4 is released ... unless I get tired of waiting and go for the MorphOS instead)

A1XE/G4 here too !
as I said to Helgis on the thread below the Eyetech news item I couldnt resist Extra features ! (Altivec - has a certain ring to it dunnit ?)
I only have a 4K cache at the mo (68030 !) so I couldn't really give a rats arse between 256 or 512K caches - besides it probably only makes a difference on Macs and Linux, who dont have the luxury of compact code blocks. (not mentioning their Bloat !)
I was considering the 750FX (G3 to you) as it is about 50 quid cheaper than the 7451 (G4) solution, and using that saving to pay for the extra sized RAM (512 as opposed to the 128 i originally plumped for) but I told myself "sod it" and went for the extra RAM anyway.
Besides, I gather that Eyetech (or their manufacturer) have a freshly delivered consignment of G4s, and are in the process of manufacture as we speak.
I wonder if me brother in law will lend me his didgie camera so I can post pictures when I get to build me machine  ? :-D

Question - does the new revision of the XE have the AMR riser ? is the AC97 sound enabled on board, and are there breakouts for the audio output ?
OK so thats three, but hey ! I've had 2 :pint:'s !

[Helgis75]

Well, i really think of going for the 800Mhz A1G3XE, and it's easier available than the G4. Anyway, as long as it's an XE, i should be able to upgrade to a powerful G4 at a later date...As a start, i don' t think it will be so much Altivec-support, really...

It's also more interesting to try out the new 750FX G3 CPU running at 800Mhz! I have now asked Datakompaniet in Norway to send back the extra 729 NOK i paid for the A1G4XE-model, so when available, they will send me the 800Mhz A1G3XE, which actually was my original order...

[Agafaster]

Whatever floats yer boat, mate, its your choice !
besides, you can put that extra (how much ? 729 Krona? 50 quid in my book, eh !) cash towards a spanky dual G4 @ 1.25GHz when they come, and be one of the first.

[Helgis75]

The XE has got the AMR-slot ditched...

[Agafaster]

doncha just love it when posts cross ?! :-P

According to benchmarks by Motorola, the 7451 is substantially faster than the 750FX at the same clockspeed.

Check:

[Helgis75]

Quite funny..hehe...But i'm glad you also think of the 800Mhz A1G3XE as very good, too..:-)

Of course, if there was an option to go for a 1.2Ghz A1G4XE, then i would have gone for that, but when both the A1G3XE and A1G4XE are 800Mhz, then the A1G3XE simply is a better choice...and someone mentioned that the G4 seems harder to deliver than the G3....Tougher shipment for the G4 than the G3...

@HyperionMP

I think one can not trust in those benchmarks.

According to Mot the FX model would not be any faster than CXe. I bet Mot has taken the values from thin air.

Even G4 values are twisted. I bet the backside cache of some G4's improve the results, etc...

In short: Motorolla is bluffing there, but hey, it's marketing material after all.

[Helgis75]

That's not quite true about the G3. The 750FX G3 at 800Mhz is clearly up to 60-70% faster than the 600Mhz 750CXe G3. The 750CXe only has a 256KB L2-cache and other limitations than the 512KB L2-Cache in the new 750FX G3. The new 750FX also has many other improvements to perfomance and overall technology...

I wrote something to that effect, but you must really learn
 not to take every little comment and make it into a fact.
You do that a lot you know.
 
 To take this case as an example, I am no employee of
Eyetech, nor do I have any inside info as to what kind of
agreements they have with chip producers. Most comments
in here is like that. I hoped that was clear in my post (I
apologize if it was not) but yet you take it as some sort of
usable fact on which to base your opinion.
 Not very serious now, when seeing the thread in context,
but if repeated in some other place as FACT, it becomes
misinformation. Such behaviour is called "jumping to
conclusions" and is one of the major ways to start a nasty
rumour. I want no part of it.
 
 Please consider this, when reading comments. Most of
what is written is just assumptions/fears/hopes/dreams,
without any factual backing at all. Learn to be a little more
discriminating.
