CPU Mini Review

Mini Review The Intel Pentium 4 HT 650 is an ageing, single-core processor. It supports Hyperthreading, but that does not yield a distinctive performance boost. Because this processor is a single-core, with no L3 cache, and is low efficiency, it is not capable of running most modern games, although games that are older or are very non-demanding should run decently. Athlon 64 FX-53 is an entry-level Processor based on the 130nm K8 micro-architecture. It offers 1 Physical Core (1 Logical), clocked at 2.4GHz and 1MB of L2 Cache. No relevant technologies are activated in a way the processor doesn't even support Virtualization. The processor DOES NOT integrate any graphics. and has a rated board TDP of 89W. Its performance is below the average and so most demanding games will not run optimally.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Athlon 64 FX-53 is noticeably better than the Intel Pentium 4 HT 650 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 4 HT 650 and the Athlon 64 FX-53 were released at the same time, so are likely to be quite similar.

{ The Pentium 4 HT and the Athlon 64 FX-53 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 4 HT and the Athlon 64 FX-53 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 Athlon 64 FX-53 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 0.2 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 <span class='gpu1Mention'>Pentium 4 HT</span> has a 1024 KB bigger L2 cache than the <span class='gpu2Mention'>Athlon 64 FX-53</span>, but neither of the CPUs have L3 caches, so the <span class='gpu1Mention'>Pentium 4 HT</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.
