Closer Look at Intel Pentium 4 670 CPU
Prescott-2M core used for the today’s newcomer, Pentium 4 670 processor, has already been discussed in detail in our article called Intel Pentium 4 6XX and Intel Pentium 4 Extreme Edition 3.73GHz CPU Review. That is why this time we will only list the major characteristics of the new CPU. For details you may always see our previous article.
Pentium 4 670 | |
Frequency | 3.80 GHz |
Package | 775-pin PLGA |
Vcore | 1.25V-1.388V |
Bus frequency | 800 MHz |
Typical heat dissipation | 115W |
Core stepping | N0 |
Max. typical case temperature | 72.8°C |
L2 cache size | 2MB |
Production technology | 90 nm |
Hyper-Threading Technology support | Yes |
Intel Extended Memory 64 Technology (EM64T) support | Yes |
Execute Disable Bit Feature (NX) support | Yes |
As we see, the newcomer doesn’t strike as with anything special. This CPU is a full analog of Pentium 4 660 with that only difference that it works at higher clock frequency.
The diagnostic CPU-Z utility provides the following information about this processor:

Here I would like to note that this CPU, just like all other processors based on Prescott-2M core with the clock frequency multiplier over 14x, supports Demand Based Switching technologies set, i.e. C1E (Enhanced Halt State) Technology, TM2 (Thermal Monitor 2) Technology and EIST (Enhanced Intel SpeedStep) Technology. These technologies make the CPU reduce its working frequency to 2.8GHz in case of overheating or in the idle mode, which is actually no surprise for us, I should say.
