Is Prescott 64-bit?
unassimilatible writes "According to The Inquirer, Intel's new Prescott has 64 bit instructions lurking inside. Could really rain on the parade of those who thought the new Athlon 64's would be supreme - especially when you look at Intel's price roadmap. Don't run out and buy an Athlon 64 just yet..."
Or there will be virtuly no software for it when it comes out and for months to come. AMD has had books on the x86-64 instruction set for years now. Not to mention emulators have been available for almost as long.
The "Prescott" has 2 32 bit cores, but the "secondary" core is missing an AGU, among other things, and this is pointing to the fact that most Prescotts have some sort of 64 bit functionality in them, but their keeping their lips shut about it?
So it seems to me that possibly Intel are waiting to see how AMD's 64 bit chip goes, and if its going better as a 32/64 bit chip then Intel's Itanium, release their Prescott with "fully" added 64 bit functionality?
Am i correct in my logic? I can't really follow why they're keeping tight about it.
Think nothing is impossible? Try slamming a revolving door.
Since 1997, all my machines have been AMD's. The K6-2 is still alive, actually. One of them (a Duron 600) has been running 24x7 for the last 3 years. My gaming rig's a dual Athlon MP2000+. My current workstation's an Athlon XP2400+. I've NEVER had any problems with them, either hardward or software (Linux).
... I know. I've administered Intel-based servers).
My biggest problem is what to do with the old mobos and processors that I put aside due to upgrading.
No, I've never had a reason to spend more for so little (it's even arguable whether you get more for spending more
For one thing, I wonder what its physical external address bus looks like. Can it address more than 4GB of physical memory without paging? The Athlon64 and Opteron can. In addition, they are discounting the benefits of an on-board memory controller. This feature alone is a huge performance boost. To top it off, AMD gear comes with HyperTransport and a host of other goodies associated with AMD, like nForce chipsets with the best on-board sound of any integrated solution (and I don't suspect this will be different with nForce3 chipsets). In short, it seems like Intel is starting a concerted marketing blitz against AMD but with little avail. With the Prescott and this new extreme edition P4 with 2.5MB cache (I shudder at the yield hit that much cache has per wafer for them), we have a lot of sudden refocus towards Intel just prior to the launch. Product quality counts, but so does marketing.
I don't know if this "dual 32-bit" thing is very plausible. Being able to do 64-bit operations is perhaps the most useless feature of the upcoming 64-bit processors. The big things about AMD64 is the larger compiler-visible register file and the ability to address > 4GB of memory.
A deep unwavering belief is a sure sign you're missing something...
This is no flame bait, it is Intel's business practice. They have done it over and over and over, if any of you were alive during the 80's you'd know about intel's 32bit move with the 386 which took forever to come out, meanwhile... other people released 32bit solutions, mostly NS and Motorola. Intel's FUD machine went into high gear and told customers to hold on since the 386 was going to be out any day then and was going to be the best processor ever. So better processors that were years ahead of the 386 got killed that way.
In the 90s Intel did the same with the Pentium and the R4000s that were going to be the basis for the ARC platform. Intel said that the Pentium was going to be out any day then and it was going to run circles around the RISC machines. The pentium was at least 4 years late and was well behind RISC offerings in performance. But Intel managed to kill the ARC consortium.
This is the latest in Intels FUD campaign, maybe it is time to break the circle... buy intel and have 64bits TODAY... screw them, with their "ooooh we may have a surprise for you" and all that nonsense.
