In terms of overall gaming performance, the Intel Pentium 4 HT 631 is marginally better than the AMD Sempron 64 LE-1100 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 64 LE-1100 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.

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 Pentium 4 HT and the Sempron 64 LE-1100 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 64 LE-1100 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 64 LE-1100 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 1.1 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. 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 Pentium 4 HT has a 1792 KB bigger L2 cache than the Sempron 64 LE-1100, but neither of the CPUs have L3 caches, so the Pentium 4 HT 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.

The Sempron 64 LE-1100 has a 41 Watt lower Maximum TDP than the Pentium 4 HT (though they were created with the same size 65 nm manufacturing technology). What this means is the Sempron 64 LE-1100 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 631 is basically a Pentium 4 HT 530 but with 2MB of cache, instead of one.
Most probably, it's not strong 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 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.
