Comparison To The Pentium D
Although using the Pentium name, the desktop Pentium Dual-Core is based on the Core microarchitecture, which can clearly be seen when comparing the specification to the Pentium D, which is based on the NetBurst microarchitecture first introduced in the Pentium 4. Below the 2 or 4 MiB of shared-L2-cache-enabled Core 2 Duo, the desktop Pentium Dual-Core has 1 or 2 MiB of shared L2 Cache. In contrast, the Pentium D processors have either 2 or 4 MiB of non-shared L2 cache. Additionally, the fastest-clocked Pentium D has a factory boundary of 3.73 GHz, while the fastest-clocked desktop Pentium Dual-Core reaches 3.2 GHz. A major difference among these processors is that the desktop Pentium Dual Core processors have a TDP of only 65 W while the Pentium D ranges between 95 to 130 W. Despite the reduced clock speed, and lower amounts of cache, Pentium dual-core outperfomed Pentium D by a fairly large margin.

“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”

“When we reflect on our past sentiments and affections, our thought is a faithful mirror, and copies its objects truly; but the colours which it employs are faint and dull, in comparison of those in which our original perceptions were clothed.”
