Future Intel chips: is this possible?

[DotheDamnTHing]

a dothan-based dual core x86-64 hyperthreaded cpu with a fsb of 1066+? i realize it may sound like something out of my ass but is it possible?

 

[So]

What? Why do you ask?

Anyway, I guess I'll take the question one part at a time.

Yes, I suppose (not personally knowing too much about hyper threading) that you could make a hyperthreaded CPU that handled x86-64 instructions, and I don't see any reason why FSB's couldn't break the 1Ghz mark down the road.

just wondering if its technically and commercially possible since intels latest offerings are quite unsavory

You find Dothan unsavory?

I find the chips from both AMD and Intel to be great, and I can't wait to see what the heated competition brings out next from both of them.

I don't believe Intel will ever make a Hyper-Threading enabled Banais or Dothan core. The reason Hyper-Threading helps the P4 is because of it's HUGE pipeline. Hyper-Threading helps to keep the pipeline full which is why it increases performance. The Banias and Dothan pipelines are short enough that using Hyper-Threading wouldn't provide much performance gain because the pipeline isn't so long that it's difficult to keep it full. Same reason AMD doesn't have any "Hyper-Threading" plans in their future... I believe the Athlon-64's pipeline is even shorter than the Banias and Dothan. (even though Intel has never publicly stated exactly how many stages are in the Banias or Dothan pipelines)

maybe i should be more clear as i meant their desktop offerings...prescott, i91/25 chipsets etc

There can't be a Dothan based Prescott... they're two entirely different cores. If a desktop chip was based off the Dothan, it wouldn't be a Prescott... they're mutually exclusive.

Take out Hyper-Threading from your original post and yes, it's entirely possible, and I'd say you'll definately see something like that in the next year or two.

i was referring to LTC8K6a post as he said if i find dothan unsavory which i do not but find their latest desktop offerings as a bit short .....by the way, i understand dothan and prescott cores are different...

Dothan and Prescott cores are the difference between apples and oranges.

Prescott has a HUGE pipeline (32stages IIRC), consumes a lot of power and puts out quite a bit of heat. Use clock speed to its advantage as low # of processes per clock cycle. IE it does less work per clock cycle.

Dothan , relatively small pipeline fromwehat we know. Consumes VERY VERY little power, and puts out VERY little heat, uses clockspeed but does more work per clock therefore lessening the need for more MHZ.

Dothan is the way that intel is moving, they realize that they cannot keep ramping up power and cooling requirements to obtain, more speed.

Also IIRC Dothan uses 2mb of cache, and runs at 533fsb whereass prescott is 1mb of cache and 800mhz FSB.

Dothan and Prescott are two different cores, and for that matter architecture as the DOthan is still based on PIII architecture whereas Prescott based on NetBurst architecture.

That's why it helps to quote when you respond to someone in particular
