Intel Pentium 4 670 3.8 GHz - JM80547PG1122MM / HH80547PG1122MM (BX80547PG3800F)

Specifications

Pentium 4 670 was released three month after the first batch of 6xx-series CPUs. The processor was clocked at 3.8 GHz, and, up to this day (May 2010), it is still one of the highest clocked Intel x86 microprocessors along with Pentium 4 570, 571, 672 and Xeon 3.8 GHz. Between Intel Pentium 4 processors, models 670 and 672 were the fastest ones. While the L2 cache on the 670 was twice as large as on the 57x CPUs, the cache had higher latency (latency is how fast the cache can supply data, the smaller number the better). Larger cache with slower access time on the 670 could cause a few applications to run slower, while some tasks run up to 12% faster than on 570 / 571 CPUs. Typically the 670 was about 5% faster than the 57x CPUs. Price-wise, the 670 was not a good 570/571 alternative at launch time due to its $200 higher introductory price. At this time (May 2010), the price of the Pentium 4 670 dropped by more than 10 times, which, in our opinion, makes it a better upgrade option than the Pentium 4 570 or 571.

Intel Pentium 4 670 is a good CPU to upgrade to in cases when your motherboard doesn't support newer Core 2 microprocessors, and you need maximum performance in single-threaded applications. When upgrading from Pentium 5xx / 6xx line processors, you can expect the following performance increase:
