Intel Pentium D 940 system consumes 253W of power with both processing CPU cores stressed, and an AMD Athlon64 FX-62 power system consumes upwards of 235WIntel Core 2 Duo processors could overclock to 3.2 GHz+ on air cooling
AMD's 90nm Athlon64 X2/FX processors have difficulty overclocking much past 3 G Hz.
If I were to take off the heat-sink from an Intel CPU, it would not lock up completely, although you might get some serious problems when taking off the heat-sink, it would simply overload and run high temps. The CPU would slow down drastically. When replacing the heat-sink, (after cooling), it would still be similar to the previous (before taking off heat-sink).
If I were to take the heat-sink from a comparable AMD CPU, the cpu would lock up, and severe damage would be done to the chip. (I.e Core Meltdown). And within seconds the chip would be up in smoke. (Literately)
Bad bad
Now
The amount of load an AMD processor can take compared to that of an Intel CPU is much better, and I mean much.
The codenamed "Dragon" from AMD (comparing to Intel i7) is similar in almost every way. Except, it consumes less energy, has more internal power, can have much greater CPU load.
One thing that is really different between Intel i7 and the "Dragon" is the hyper-threading. (Yes that is it.)
AMD can proccess faster, and more.
Intel can
look like it is better. But you have to look deep down.
