CPU Mini Review

Mini Review Pentium N3520 2.16GHz is an energy efficient quad core mobile processor, based on the 22nm Silvermont architecture. <br/> The Pentium N3520 2.16GHz offers 4-Cores, clocked at 2.16GHz and weak integrated graphics. <br/> The Pentium N3520 2.16GHz does not offer the the multi-threading technology but it offers the Turbo Boost technology which raises its clock speed to up to 2.42 GHz. <br/> Still, its TDP is of only around 8 Watts and its performance is quite far from Intel's Core i3 Series. Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.

Gaming Performance Comparison

In terms of overall gaming performance, the Intel Pentium N3520 2.16GHz is noticeably better than the Intel Celeron Dual-Core 867 1.3GHz 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 N3520 2.16GHz and the Celeron Dual-Core 867 1.3GHz were released at the same time, so are likely to be quite similar.

The 4 has 2 more cores than the Celeron Dual-Core 867. { With 4 cores, the 4 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 N3520 2.16GHz and Celeron Dual-Core 867 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 N3520 2.16GHz has a 0.86 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 4 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 <span class='gpu1Mention'>Pentium N3520 2.16GHz</span> has a 1536 KB bigger L2 cache than the <span class='gpu2Mention'>Celeron Dual-Core 867</span>, and although the Pentium N3520 2.16GHz does not appear to have an L3 cache, its larger L2 cache means that it wins out 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.
