CPU Mini Review

Mini Review Turion II Neo K625 is a Dual core mobile CPU based on the 45 nm Geneva Core. <br/> It features 2 cores, clocked 1.5GHz and the fastest supported memory is DDR3-1066. <br/> Its performance is below the average but decent enough to run most games from medium to high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require very reduced settings to be played optimally. Phenom II X3 P820 is a triple core mobile CPU based on the Champlain Core and therefore related to the Athlon II X3 Desktop Series. <br/> It features 3 cores, clocked 1.8GHz and the fastest supported memory is DDR3-1066. <br/> Its performance is average and decent enough to run most games at high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require reduced settings to be played optimally.

Gaming Performance Comparison

In terms of overall gaming performance, the AMD Phenom II X3 P820 is noticeably better than the AMD Turion II Neo K625 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 Turion II Neo K625 and the Phenom II X3 P820 were released at the same time, so are likely to be quite similar.

The 3 has 1 more core than the Turion II Neo. However, while the 3 will probably perform better than the Turion II Neo, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. { Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

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 Turion II Neo and Phenom II X3 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 Phenom II X3 has a 0.3 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 enough that it possibly indicates the superiority of the 3.

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'>Turion II Neo</span> has a 512 KB bigger L2 cache than the <span class='gpu2Mention'>Phenom II X3</span>, but neither of the CPUs have L3 caches, so the <span class='gpu1Mention'>Turion II Neo</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.
