The Pentium D line of processors from Intel was the direct successor of the Pentium Dual-Core processor, the first processor to be truly multi-core. Two of the lower-end models of the Pentium D processor are the 820 and the 920. While there are a couple of differences between these two devices, they are much more alike than they are different.
Codename
During development of the processor, the Pentium D 820 was known as the "Smithfield" while the Pentium D 920 carried the name "Presler."
Nanometer
The Pentium D 820 is a 90nm processor, whereas the Pentium D 920 is a 65nm processor. The smaller nanometer count helps with heating issues and power consumption.
L2 Cache
The Pentium D 820 has an L2 Memory Cache of 2MB, divided between two 1MB centers. The Pentium D 920 has an L2 Memory Cache of 4MB divided between two 2MB cores.
Frequency Speed
Both the Pentium D 820 and the Pentium D 920 operate at a frequency of 2.80 GHz.
Price
When the Pentium D 820 was released, it carried a price of $241. The Pentium D 920, which was released a year later, carried the same price.
