In terms of overall gaming performance, the AMD FX-8320E is massively better than the AMD Athlon II X2 280 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-8320E was released over a year more recently than the Athlon II X2, and so the FX-8320E is likely to have better levels of support, and will be more optimized for running the latest games.

The FX-8320E has 6 more cores than the Athlon II X2. With 8 cores, the FX-8320E 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 FX-8320E and Athlon II X2 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 Athlon II X2 has a 0.4 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 FX-8320E.

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-8320E has a 6144 KB bigger L2 cache than the Athlon II X2, and although the Athlon II X2 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 Athlon II X2 has a 30 Watt lower Maximum TDP than the FX-8320E. However, the FX-8320E was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Athlon II X2 is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

CPU Mini Review

Mini ReviewFX-8320E is an energy efficient CPU based on the 32nm Piledriver architecture.

It offers 8 Physical Cores (8 Logical), initially clocked at 3.5GHz, which may go up to 4.0GHz 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 95W.

Its rank and specifications are still predicted.
Athlon II X2 280 is a recent addition to AMD's Athlon II series of microprocessors, built using a 45 nm technology fabrication, using a Regor core. It is as of now, the fastest Athlon Dual Core CPU, and the only one released in 2013. It packs two cores clocked at 3.6GHz each, and 2MB of L2 Cache memory. The thermal design power should not exceed 65 watts.
