In terms of overall gaming performance, the AMD FX-8120 is massively better than the Intel Pentium Dual Core E2220 2.40GHz 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 FX-8120 was released less than a year after the Pentium Dual Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The FX-8120 has 6 more cores than the Pentium Dual Core. With 8 cores, the FX-8120 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 Dual Core and FX-8120 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 FX-8120 has a 0.7 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 FX-8120 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 FX-8120 has a 7168 KB bigger L2 cache than the Pentium Dual Core, and although the Pentium Dual Core 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.

The Pentium Dual Core has a 60 Watt lower Maximum TDP than the FX-8120. However, the FX-8120 was created with a 33 nm smaller manufacturing technology. Overall, by taking both into account, the FX-8120 is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

CPU Mini Review

Mini ReviewThe Intel Pentium Dual-Core brand refers to mainstream x86-architecture microprocessors from Intel. With the exception of a few early Yonah based mobile models, they are now all based on the 64-bit Core microarchitecture. Pentium Dual-Core lacks the SSE4.1 instruction found in the 45 nm Core 2 processors.FX-8120 is a high-end CPU based on the 32nm Bulldozer architecture.

It offers 8 Physical Cores (8 Logical), initially clocked at 3.1GHz, which may go up to 3.4GHz and 8MB of L3 Cache.
Among its many features, Turbo Core and Virtualization are activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrated any graphics. and has a rated board TDP of 125W.

It is a powerful Octa Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
