CPU Mini Review

Mini Review The Pentium Extreme Edition based on the dual-core Pentium D branded Presler was introduced as the 955 model, at 3.46 GHz, and used a 1066 MT/s FSB compared to the 800 MT/s in the non-Extreme edition. A second version, the 965 at 3.73 GHz followed in March 2006. Both CPU's also feature Hyper-Threading Technology. Many overclockers, however, had been able to overclock the core to 4.26 GHz using air cooling simply by raising the unlocked CPU multiplier. The 'Presler Extreme Edition' would run only combined with the Intel 975X chipset (it could also work with the 955X chipset, though this combination was not supported by Intel). The i975X featured the ICH7R southbridge and supported all LGA 775 (Socket T) Pentium 4, Pentium D, and Pentium Extreme Edition branded processors. Sempron 150 is a single core desktop CPU based on the K10 architecture. <br/> Its only core is clocked at 2.9GHz and the memory controller supports DDR3 up to 1333MHz. <br/> Benchmarks indicate the performance is very limited and not recommended for today's modern demanding and very demanding games.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Pentium D Extreme Edition 3.73GHz is marginally better than the AMD Sempron 150 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 Pentium D Extreme Edition 3.73GHz and the Sempron 150 were released at the same time, so are likely to be quite similar.

{ The Pentium D Extreme and the Sempron 150 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, thePentium D Extreme and the Sempron 150 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 Pentium D Extreme and Sempron 150 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 D Extreme has a 0.83 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'>Sempron 150</span> has a 1022 KB bigger L2 cache than the <span class='gpu1Mention'>Pentium D Extreme</span>, but neither of the CPUs have L3 caches, so the <span class='gpu2Mention'>Sempron 150</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.
