In terms of overall gaming performance, the AMD Sempron 150 is noticeably better than the Intel Pentium 4 HT 531 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.

The Sempron 150 was released less than a year after the Pentium 4 HT, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Pentium 4 HT 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, the Pentium 4 HT 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 4 HT 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 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 Pentium 4 HT and the Sempron 150 have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the Sempron 150 has a 48 KB bigger L1 cache, so would probably provide better performance than the Pentium 4 HT, 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.

The Sempron 150 has a 39 Watt lower Maximum TDP than the Pentium 4 HT, and was created with a 45 nm smaller manufacturing technology. What this means is the Sempron 150 will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewPentium 4 HT 531 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.
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.
Sempron 150 is a single core desktop CPU based on the K10 architecture.
Its only core is clocked at 2.9GHz and the memory controller supports DDR3 up to 1333MHz.
Benchmarks indicate the performance is very limited and not recommended for today's modern demanding and very demanding games.
