The Celeron 440 2.0GHz and Pentium 4 3.0GHz are not from the same family of CPUs, so their clock speeds are by no Problematically, unless the two CPUsĪre from the same family, this can only serve as a general guide and nothing like an exact comparison,īecause the clock cycles per instruction (CPI) will vary so much. More important for gaming than the number of cores and threads is the clock rate. Run slightly older games fairly effectively. With a decent accompanying GPU, the Celeron 440 2.0GHz and the Pentium 4 3.0GHz may still be able to The Celeron 440 2.0GHz and the Pentium 4 3.0GHz both have 1 cores, and soĪre quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running In 2004, the initial 32-bit x86 instruction set of the Pentium 4 microprocessors was extended by the 64-bit x86-64 set. NetBurst differed from the preceding P6 (Pentium III, II, etc.) by featuring a very deep instruction pipeline to achieve very high clock speeds (up to 3.8 GHz) limited only by TDPs reaching up to 115 W in 3.4 GHz ?3.8 GHz Prescott and Prescotts 2M cores.

They had the 7th-generation x86 microarchitecture, called NetBurst, which was the company's first all-new design since introduction of P6 microarchitecture of the Pentium Pro CPUs in 1995. The Pentium 4 brand refers to Intel's line of single-core desktop and laptop central processing units (CPUs) introduced on Novemand shipped through August 8, 2008. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range. Many of the Celeron designs have achieved a very high bang for the buck, while at other times, the performance difference has been noticeable. In some cases, the effect was significant and in other cases the differences were relatively minor. These missing features have had a variable impact on performance. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. Celeron processors can run all IA-32 computer programs, but their performance is somewhat lower when compared to similar CPUs with higher-priced Intel CPU brands. The Celeron brand has been used by Intel for several distinct ranges of x86 CPUs targeted at budget personal computers.
