CPU Mini Review

Mini Review The Celeron brand has been used by Intel for several distinct ranges of x86 CPUs targeted at budget personal computers. 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. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. These missing features have had a variable impact on performance. In some cases, the effect was significant and in other cases the differences were relatively minor. Many of the Celeron designs have achieved a very high bang for the buck, while at other times, the performance difference has been noticeable. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range. In January 2002 Intel released Pentium 4s with a new core code named "Northwood" at speeds of 1.6 GHz, 1.8 GHz, 2 GHz and 2.2 GHz. Northwood (product code 80532) combined an increase in the L2 cache size from 256 KB to 512 KB (increasing the transistor count from 42 million to 55 million) with a transition to a new 130 nm fabrication process. Making the processor out of smaller transistors means that it can run at higher clock speeds and produce less heat. In the same month boards utilizing the 845 chipset were released with enabled support for DDR SDRAM which provided double the bandwidth of PC133 SDRAM, and alleviated the associated high costs of using Rambus RDRAM for maximal performance with Pentium 4.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Pentium 4 2.26GHz is marginally better than the Intel Celeron 600MHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

Both the Celeron 600MHz and the Pentium 4 2.26GHz were released at the same time, so are likely to be quite similar.

Both CPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful CPUs. Neither of these will be able to run the latest games in any playable way.

{ The Celeron 600MHz and the Pentium 4 2.26GHz both have 1 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, theCeleron 600MHz and the Pentium 4 2.26GHz may still be able to run slightly older games fairly effectively.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Celeron 600MHz and Pentium 4 2.26GHz are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Pentium 4 2.26GHz has a 1.66 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is probably a good indicator that the is superior.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The <span class='gpu2Mention'>Pentium 4 2.26GHz</span> has a 384 KB bigger L2 cache than the <span class='gpu1Mention'>Celeron 600MHz</span>, but neither of the CPUs have L3 caches, so the <span class='gpu2Mention'>Pentium 4 2.26GHz</span> wins out in this area with its larger L2 cache.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.
