Back when RISC CPUs didn't exist. Prior to the Power Macintosh debut in 1994 that used PowerPC RISC CPUs, Apple used varients of the Motorola 68000, 68020, 68030 and 68040 CISC CPUs in Macs and Powerbooks.
Wow. And not so long ago people were complaining about how unstormy it was prior to WWDC. The only way I see Apple moving to Intel is if CEOs of Intel, Dell, HP, Gateway and Acer are standing up there with Steve at the WWDC keynote and promising that they will be shipping Mac OS X for Intel by the time Xbox 360 comes out this fall, or at least a converged home device to compete with Xbox and PS3.
There aint no such thing as a free lunch. Cell is a 200+ million transistor, 200+ sq mm microprocessor running at 3.2 GHz. The idea that it can perform to the theoretical numbers yet run cool enough to be used in a laptop sounds very much like a free lunch. I think that laptop CPU power budgets will grow to the 40 Watt range in the next couple of years. CPU power budgets have grown, commensurate with increased performance, very consistently since laptops were first...
TANSTAAFL. It hasn't been ascertained that Cell is in fact more appropriate for laptop uses (let alone desktop uses). If Cell (1 PPE + 8 SPE) at 3.2 GHz is 80 Watts, and the Realworldtech SPE schmoo plot is correct, then 1 PPE + 512 kByte L2 burns 30 to 40 Watts. It's possible though for IBM to produce a low power PowerPC chip for laptop uses though. If Intel can produce a 2.13 GHz Pentium M 770 at 27 Watts TDP, IBM should be able to produce a 2 GHz 970fx within 5 Watts of...
I've been a Powerbook G5 advocate for so long, ever since the 1st gen Power Mac G5s came out, that I'm beginning to wonder if its becoming a complex for me. Apple and IBM were planning to have a Powerbook G5 and 970fx chips to go into them at least in early 2004. I bet Apple wanted to release a Powerbook G5 in Summer of 2004, but alas things didn't go right at the 90nm fab. IBM had an application note, Thermal Considerations: PPC970FX, in early 2004 which stated...
They should legalize it so Ricky Williams can play football again!
The two FPU units in the 970 execute single and double precision with the same latencies and are fully pipelined for both. It's 11 GFLOPS DP for a 2.7 GHz 970fx. The 22 GFLOPS Henriok quoted was an AltiVec number, and we all know AltiVec only does single precision.
This doesn't make sense. Single and double precision are terms indicating the accuracy, the number of digits of precision, typically for floating point math. 32 or 64 bit chips are terms indicating the width of the integer unit and how much memory it can support. A single precision value is represented in the chip in binary by a "word" 32 bits long (or wide). A double precision value is represented by a 64 bit long binary. Yes, it's confusing. Every single PowerPC chip...
How many digits of accuracy does the SPE have compared to other CPUs? It doesn't support denormalized numbers and Realworldtech says it rounds to zero. Those could be some pretty big exceptions for a lot of people.I can agree with you here. It's a big win for media and graphics. How big of a win it is compared to some other design utilizing 200+ million transistors, I think is up for debate. I'll be a skeptic about this until Apple comes out with the hardware, or perhaps...
I plan on switching to Cingular in the very near future and need some help choosing a "smartphone". Which is better? The MS powered SMT 5600 or the Palm powered Treo 650? Plan on synching with Outlook, viewing email, viewing Office files, typing notes, keeping contacts and schedules. I really like the thumb-board and high resolution display, but the Treo 650 runs a 3 year old operating system, is supported by a "troubled" company, and costs ~450$. The SMT 5600 is...
