CPU Mini Review

Mini Review The Pentium 4 HT 505 is an ageing processor based on Intel's Prescott 90nm microarchitecture. Given its age, lack of L3 cache, and single processing core, it is no longer suitable for high-end gaming, and is inferior to any recent products. It will still serve decently enough in an old computer that only has support for the LGA775 socket, but upgrading would be far more favorable than using this processor at this stage in its life. Pentium 4 CPUs introduced the SSE2 and, in the Prescott-based Pentium 4s, SSE3 instruction sets to accelerate calculations, transactions, media processing, 3D graphics, and games. Later versions featured Hyper-Threading Technology (HTT), a feature to make one physical CPU work as two logical CPUs. Intel also marketed a version of their low-end Celeron processors based on the NetBurst microarchitecture (often referred to as Celeron 4), and a high-end derivative, Xeon, intended for multiprocessor servers and workstations. In 2005, the Pentium 4 was complemented by the Pentium D and Pentium Extreme Edition dual-core CPUs

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Pentium 4 HT 524 is marginally better than the Intel Pentium 4 HT 505 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 505 and the Pentium 4 HT 524 were released at the same time, so are likely to be quite similar.

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 HT 505 and the HT 524 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, theHT 505 and the HT 524 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 HT 505 and the HT 524 are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.4 GHz faster base clock rate, the HT 524 manages to provide slightly better performance than the <span class='gpu1Mention'>HT 505</span>.

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'>HT 505</span> has a 1023 KB bigger L2 cache than the <span class='gpu2Mention'>HT 524</span>, but neither of the CPUs have L3 caches, so the <span class='gpu1Mention'>HT 505</span> wins out in this area with its larger L2 cache.

The System Bus Speed is important for providing higher bandwidth, and with higher bandwidth the system has the capacity to move more data over a certain time period than it would with lower bandwidth.

The HT 505 and the HT 524 both have System Bus Speeds of 533 MHz, and so have the same limits when it comes to the size of the data being processed at once.

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.

Both the HT 505 and the HT 524 have the same TDP of 84 Watts, and were created with the same manufacturing size of 90 nm, which means they will affect your yearly electricity bill about equally.
