CPU Mini Review

Mini Review 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. Pentium 4 HT 530 is basically a Pentium 4 3.0GHZ but with Hyper-Threading technology support. It still has only one core but the Hyper-Threading allows it to perform multiple tasks as if there's more than one core doing the work. This obviously doesn't affect today's games as a single 3.0GHZ core even with HT isn't, most probably, enough to handle today's games at high settings. <br> Compared to the original Pentium 4 3.0GHZ the performance is significantly better but the Prescott architecture is one of intel's worst and the performance may hinder due to overheating issues.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Sempron 150 is noticeably better than the Intel Pentium 4 HT 530 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 150 and the Pentium 4 HT 530 were released at the same time, so are likely to be quite similar.

{ The Sempron 150 and the Pentium 4 HT 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 150 and the Pentium 4 HT 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 150 and Pentium 4 HT 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 HT has a 0.1 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. 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 150 and the Pentium 4 HT have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the <span class='gpu1Mention'>Sempron 150</span> has a 48 KB bigger L1 cache, so would probably provide better performance than the <span class='gpu2Mention'>Pentium 4 HT</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.
