T-bred kaldere enn Pally?


Anbefalte innlegg

Veit dette høres ut som et dustete spørsmål, men det er seriøst, veit at t-bred produserer mindre varme, men coren er jo mye mindre, mao mye mindre flate å trekke varme vekk fra, hva har dette å si i praksis? Hvor er det lettest å holde coren kald? T-bred eller Pally? Fint om noen har noen tester som tar opp dette, har ikke funnet noen enda.

Tja, ser ikke ut til å være den store forskjellen i praksis. Mindre core, og kun litt mindre effektforbruk utgjør visstnok ikke så veldig mye iflg. Toms Hardware. Mindre core og større trøbbel med å feste kjøler? Nye krav til kjølere fra AMD iflg. testen også...

By switching to 0.13-µm technology, the power consumption and core voltage of the Athlon XP with the Thoroughbred core will sink drastically. However, this only applies to the "smaller" models with lower clock frequencies. The table below shows that only the Athlon XP 1700+, 1800+ and 1900+ work with a significantly lower core voltage of 1.5 Volt. The heat dissipation is clearly lower with only three of the processors, if you compare them to the same Athlon XP models with the Palomino core.

 

The new top-of-the-line Athlon XP 2200+, however, works which a voltage of 1.65 Volt - which is a difference of only 0.1 Volt compared to its predecessor.

 

Viewed with a critical eye, you can determine that decrease in die size has not made much of a difference in heat dissipation, because at a maximum heat dissipation of 67.0 Watt, the Athlon XP 2200+ with Thoroughbred core emits only 4.1 Watt less than the Athlon XP 2100+ with the Palomino core. In total, the heat dissipation of the top Thoroughbred model has an advantage of 5.7% over the Palomino. Therefore, the Athlon XP 2200+ remains in a hot spot, despite the 0.13-µm technology.

 

When switching from the Athlon XP with the Palomino core to the Athlon XP with the Thoroughbred core, the topic of sufficiently cooling the processor becomes increasingly important. Even though the new Athlon XP has only a marginal performance increase (5.7% less with the top 2200+ model than the previous model with the Palomino), a higher quality CPU cooler is necessary.

 

To explain this - since the CPU surface has been reduced by 40%, this means that there's automatically less surface area to dissipate the heat. Here, we wonder why AMD doesn't use a heat spreader à la Intel Pentium 4 or AMD "Hammer". For OEM manufacturers and buyers of the new Athlon XP processors, there are new guidelines from AMD, valid starting June 10, 2002:

 

Only a few select CPU coolers can be used - they must have a copper contact plate for the surface of the CPU die, or use some other kind of contact plating with adequate heat transfer capability. To put it clearly: if you want to equip your PC with a Thoroughbred Athlon XP, you can get rid of your aluminum cooler. As it is, if the new Athlon XP dies a thermal death when used together with a cheap cooler, you will get no guarantee from AMD

Dere må være de eneste gjenlevende som tror at Toms Hardware er en upartisk kilde. De er klart på parti med Intel. Bare se litt på forskjellige reviews de har hatt.


 

Klar over at tom har litt intel-bias, men det betyr ikke at alt de sier er ufornuftig.

 

Noen som har en vifte å anbefale som er noenlunde kald og ikke minst stille da? (og helst ikke jævlig dyr).
