Motorola announced the MPC7457 and MPC7447 today:


The newest and fastest members of the Motorola, Inc. (NYSE:MOT) G4 family of PowerPC® processors, the MPC7457 and MPC7447, are now available. The devices run at speeds up to 1.3 GHz, making them the highest performing G4 host processors available for embedded applications.

The MPC7457 and MPC7447 can perform at 1 GHz while consuming less than 10 Watts, making them ideal for high-performance, power dissipation-sensitive applications such as network control plane processing.

apple...if your gonna do it, only do it to bridge the gap between now and the 970 otherwise SCREW MOTO!

wait...nevermind there not gonna be available until 4th quarter...and only in 1ghz??? what the!!...thats so sad

look: production expected to commence in Q4 2003. Suggested retail pricing for the MPC7457 at 1 GHz is expected to be $189 (USD) in quantities of 10,000.

yay first post!!
 
Weren't these supposed to be the first ones to support DDR on the FSB?

(I guess not)


(BTW: The "1st post" comments were cute the 1st 100000000 times :rolleyes: )

I would guess that Moto doesn't see a demand for that in the embedded application market. (I also have absolutely no knowledge about that market ;) )

[edit] ... It sure seems like they could care less about the desktop market. [/edit]
 
I notice this press release said these were the newest and fastest G4's yet they only go 1.3 ghz. dont we have a powermac at 1.42ghz so how could these be the fastest?the article also stated that they scaled up to 1.3. If this is so then i dont seeing this as the chip to move the powermacs into the future. Anyone say 970!
 
I didn't see any mention about the bus speeds.

They probably wanted to downplay that little tidbit of information.

At least Moto's using 130 nm and SOI.

I would hazard a guess that these particular chips will only be for imbeded applications, not for computers.

Guessing that the new XServe is using these, I guess it's an imbeded application. :)
It makes sense to use them due to the lower heat.
 
Hmmm, this is strange.

Maybe the Xserves are using these things, or maybe they're just 7455s clocked to 1.33 for heat dissipation reasons. Either way, they certainly aren't the fastest G4s, unless Apple really does overclock the chips in the PowerMac...

biscuit
 
I dont know for sure but i would even doubt these are in the xserve,hate to bring this up again but maybe apple is running the you know what out of 1 giger g4s so they can sell em as 1.42. didnt i read that some people had them as high as 1.5 but then started to have issues. This really makes me think that moto isnt going anywhere when it comes to the mac and that perhaps the 970 is coming our way. The article didnt say squat about desktops.And if these will go up to 1.3 then the 1.33 in xserve may be the 7455 still?
 
Probably 7455

I believe these are the 7455's in the Xserve. They clearly state that the L2 cache is at 256KB and not the 512KB cache that these new chips have. Darn.
 
could this be the next gen iBook chip?

or maybe for a tablet style device?

sounds similar to the Transmeta Crusoe series chips to me...

Maybe so but also notice mass production is not supposed to start untill 4th qtr?Is apple going to leave everything like it is for a year? I hope not and doubt it.

How did you continue to believe this for so long? Many people such as myself have shot down this silly idea time and time again on these very forums.

Dont Hurt Me:

To quote the press release:
AUSTIN, Texas - February 10, 2003 - The newest and fastest members of the Motorola, Inc. (NYSE:MOT) G4 family of PowerPC® processors, the MPC7457 and MPC7447, are now available.

So where did you get 4th quarter from?

Requoting the article. :D

Read much further and you'll get:
Pricing and Availability
Alpha samples of the MPC7457 and MPC7447 PowerPC processors are available today to selected customers. General market sampling is planned for March, with production expected to commence in Q4 2003. Suggested retail pricing for the MPC7457 at 1 GHz is expected to be $189 (USD) in quantities of 10,000.

Dang, I even searched for "quarter". Guess I should have looked for "Q4" too.

Anyway I don't think 10W at 1.0ghz is surprising, seems like exactly what a simple chip like a G4 should be doing. What is suprising is how much power the 7455 eats while getting to 1.42ghz. I've never seen a real number published, but people who are knowledable about these things are saying 50W-60W.
