CPU Mini Review

Mini Review Sempron has been the marketing name used by AMD for several different budget desktop CPUs, using several different technologies and CPU socket formats. The Sempron replaced the AMD Duron processor and competes against Intel's Celeron series of processors. AMD coined the name from the Latin semper, which means always, to suggest the Sempron is suitable for daily use, practical, and part of everyday life. 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.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Celeron 450 2.2GHz is marginally better than the AMD Sempron 64 LE-1250 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 Sempron 64 LE-1250 and the Celeron 450 2.2GHz were released at the same time, so are likely to be quite similar.

{ The Sempron 64 LE-1250 and the Celeron 450 2.2GHz 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, theSempron 64 LE-1250 and the Celeron 450 2.2GHz 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 Sempron 64 LE-1250 and Celeron 450 2.2GHz 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 Sempron 64 LE-1250 and the Celeron 450 2.2GHz both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. As such, we need to look elsewhere for more reliable comparisons.

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 Sempron 64 LE-1250 and the Celeron 450 2.2GHz have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the <span class='gpu1Mention'>Sempron 64 LE-1250</span> has a 64 KB bigger L1 cache, so would probably provide better performance than the <span class='gpu2Mention'>Celeron 450 2.2GHz</span>, at least in this area.

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.
