Prescott - real world temps

[halcyon]

We already knew TDP for Prescott was going to be high. Intel said heat was not going to be an issue.

I'm not sure Intel was telling us the truth:

From Xbit Labs Prescott review:

CPU idle temp / load temp (Celcius)
P4 3.2Ghz Prescott 45 C / 61 C
P4 3.2Ghz Norhwood 30 C / 48 C
P4 3.2Ghz Extreme E. 32 C / 51 C

All CPUs measured under same conditions (mobo, cooler, etc) using on-die thermal diode.

Hello:

The review over at Ace's Hardware has a temperture rise of ~19C over Northwood at the same speed doing the same thing...

Despite using the most advanced 90 nm process technology, it is clear that Prescott could use the freezing cold night-time temperatures of Mars to cool down. With 103W TDP it is the current record holder. Intel told us that we could cool the CPU with the same heatsink that we used for the Pentium 4 3.2 GHz.


"Brave" is clearly surprised that Prescott is such Hot dog!

The temperature difference was big, though. After running a 3DSMax rendering and restarting the PC, the BIOS reported that the 3.2 GHz Northwood was at about 45-47°C, while Prescott was flirting with 64-66°C. Mind you, this is measured on a motherboard completely exposed to the cool air (18°C) of our lab.

woot, i see stock watercooling in the future!

Prescott will have to scale incredibly quickly to outperform the Athlon 64, because the latter scales excellently with clockspeed, and we definitely prefer Cool'n'Quiet over Hot'n Prescott!
