Motorola's MPC7457 Soon?

New chips for everyone. Keeps on getting better. The 7457 and then the 970. Can't be bad for Apple.

Better late than never Moto. I guess.... :rolleyes:

hmm, this is interesting news, any news of progress in the processor realm is good news to me. I'd be interested to see how quickly, if at all, these get introduced into systems

Just rumors

And so little!:rolleyes:

I like hearing rumors of possible upcoming procs. Makes me feel like there is a light at the end of the tunnel. Maybe we'll see a new xServe with that proc in it. That would make sense with the large lever 3 cache. But what the hell do I know, I wouldn't know if it would help a server or not. Anyone!?! :)

It's doubtful the chip is a complete rumor, since Motorola is going to be talking about the chip at SNDF 2003 Dallas. This is in March..

SNDF 2003 Dallas Host Processor Topics

edited for length

Session: Understanding and Utilizing Caches on the MPC7457 PowerPC Host Processor, Including Backside L3 and Private Memory
Session ID: H1103
Level: Basic
Presenter: Ted Peters, Applications Engineer, Motorola Networking & Computing Systems Group
Abstract: This session will cover several topics on how to manage the three levels of caches available on the MPC7457 PowerPC Host Processor. The topics will include cache locking, utilizing L3 as private memory, data movement and replacement algorithms between the three cache levels, initializing and testing the caches, and cache-related performance monitor counters. This talk will also help system designers understand the benefits and trade-offs of implementing an L3 backside cache.

Session: Specifying Power Consumption and Heat Sink Requirements for the MPC7447/7457 PowerPC Microprocessor
Session ID: H1106
Level: Intermediate
Presenter: Malcolm Ward, PowerPC Applications Engineer, Motorola Networking & Computing Systems Group
Abstract: This session will evaluate the power consumption on our newest host processors, MPC7447 and MPC7457, when performing the workloads described in the benchmarking session. This evaluation will examine the core and I/O power consumption when using an L2 cache, an L3 cache, a floating point unit and an AltiVec™ unit. We will also look at heat dissipation and how to determine if you need a heat sink for your processor.

Session: Motorola PowerPC Processor Benchmark Update, Including the Latest Performance Data for the New Motorola MPC744/57 PowerPC Host Processors
Session ID: H1112
Presenter: Chuck Corley
Abstract: How does the performance of the MPC7447/7457 compare to competition? To other PowerPC parts? This subject has been very popular at previous Smart Networks Developer Forums. It will include updated EEMBC performance figures for the MPC7447/7457 and other benchmarks as available.

Quite intresting...

If it turns out to be true... this is just very intresting.

Edit: Bus interconnects?!?!?!?
desussion on the processor itself with new features and more L3. cool.

what the world needs now, is cubes, great cubes.


i want one!

Hmm.

Just wondering why Apple hasn't put them into new PM. May afterall be that they re moving away from Motorola for their pro line. 970 comes to my mind.

This could actually be a great stop on the way to the 970. A G4 at 1.5GHz or so (heck, overclocked PowerMacs have already hit 1.5) with the huge cache and full-DDR usage would provide a significant speed boost over the current batch of PowerMacs.

Not that it would necessarily clock this high, but imagine this:

- dual-1.6GHz G4s
- 1MB L2 Cache (in total)
- 8MB L3 Cache (in total)
- 200MHz System Bus (400 effective)
- Hella fast DDR-RAM

7,000$ base price (for that model)
