AMD Athlon XP 2100+ (1.73GHz) to be Released Next Week?

[KenAF]

Just for the hell of it, here are Intel's max numbers for old "Williamette" P4 (w/ .18um aluminum) that was recently replaced:

1.4 2.1V 55.3W
1.5 2.1V 57.9W
1.6 2.1V 60.8W
1.7 2.1V 63.5W
1.8 2.1V 66.1W
1.9 2.1V 72.8W
2.0 2.1V 75.3W

And here are Intel's max numbers for the new "Northwood" P4" (w/ .13um copper):

1.8A 1.5V 49.7W
2.0A 1.5V 52.4W
2.2A 1.5V 55.1W
2.4A 1.5V 57.8W (projected)
2.6A 1.5V 60.5W (projected)
2.8A 1.5V 63.2W (projected)
3.0A 1.5V 66.0W (projected)
3.4A 1.5V 71.5W (projected)

From these numbers, it's quite obvious how the P4 is able to overclock so well. Even at 3.4GHz, the new P4 still produces less heat than the old "Williamette" P4 at 2.0GHz. Clearly, Intel experienced some benefit from the improved processor layout, the copper interconnects (used by AMD after 900MHz), and, of course, the .13um interconnects. The new P4 core also has the advantage of a 116mm^2 surface area plus a heat spreader, compared to 80mm^2 and no heat spreader for the Thoroughbred.

<< I am just guessing, but I would think that a .13 micron 2100+ could reach 2158 MHz (13*166). Right now I have an unlocked TBird running at 175 MHz FSB and wouldn't be willing to ugrade until the AthlonXP could reach a 166 MHz FSB w/ a locked multiplier. >>



Think you mean 2166MHz (.66...)

These are typical, not max. figures for the P4. Max numbers (from Ace's Hardware):

Willamette Pentium 4 2000 MHz
Max: 92W
Typical: 72W

Northwood Pentium 4 2000 MHz
Max: 66W
Typical: 52.4W

Northwood Pentium 4 2200 MHz
Max: 70W
Typical: 55.1W

And just to show that Athlon XPs do dissipate significantly less heat than their Willy counterparts 🙂

Athlon XP 2000+
Max: 72W
Typical: 62.5W

<< There are changes besides the die shrink, it's supposed to feature 512K L2 cache as well. >>



It's rumored it may, but AMD hasn't reported anything about 512K L2 cache increase.

That would be nice...

Nice job on the OC too 🙂 I can't get mine to boot into windows at 150 FSB :\

My MB sucks.

Thanks. The Iwill XP333 is a really nice board. OT a bit, I just ordered the HHC-001 Coolermaster w/ heat pipes so I should reach alot higher soon. 🙂 Unlocking the multiplier on the XP sucks so I was hoping AMD would release a 333 MHz FSB version. That would be the smart thing to do.

I hope the TBred will run on current motherboards like the Iwill XP333. Intel's .13 micron for the PIII required a new chipset.

BTW, 166*13 = 2158 MHz. Maybe the mobo would show 2166 MHz though. 🙂

That's not true; straight from Intel's site, "processor power dissipation simulations indicate a maximum application power in the range of 75% of the maximum power for a given frequency."

It's not really possible to directly compare heat dissipation for both processors with those figures, as AMD lists results for "typical" thermal power at 15% load, maximum power at some undefined percentage, while Intel only lists processor power dissipation at 75% load. People are comparing the Athlon's heat dissipation at 15% to a P4 at 75% load, and that doesn't make sense. Some sites have decided to just divide Intel's figure by 0.75 or some other number to get the true 100% load figure, but you can't do that. It's not sound physics. I don't know where Aceshardware got their figures; they didn't get them from Intel's site.

Either way...what is clear...is that a P4 overclocked to 2700+MHz still runs cooler than an Athlon 2000+ at stock.

Really, all the evidence from AMD has shown that T-Bred is just a die shrink, nothing new.

Where's the evidence? Links please...

Thats a little closed minded man

Assumption is the mother of all screw ups. I haven't seen anything that doesn't indicate 512K L2 cache (most websites are all pointing at that number) and I prefer to have the facts straight from the horses mouth. I guess because I prefer facts over rumor means I'm closed minded? Sure.

Yep, it looks like they're coming soon:

AMD is shrinking the overall die size which means that they are packing about the same heat as an XP per its volume. Don't expect much of an overclock unless they increase the die size back to 100mm2.

The 80mm2 is so tiny that its just pushing the envelope too much. They will need a heat spreader to prevent that small of core from fracturing too easy. By the time you use a heatspreader it defeats the cost advantage of the die shrink.

it seems as if they've been coming soon for a while now
