Gaming Performance Comparison

Recommended System Requirements
Game Xeon E5-2440 v2 FX-4300

In terms of overall gaming performance, the Intel Xeon E5-2440 v2 is massively better than the AMD FX-4300 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 Xeon E5-2440 v2 was released over a year more recently than the FX-4300, and so the Xeon E5-2440 v2 is likely to have better levels of support, and will be more optimized for running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Xeon E5-2440 v2 has 4 more cores than the FX-4300. 8 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the FX-4300 is more than enough for gaming purposes. However, if you intend on running a server with the Xeon E5-2440 v2, it would seem to be a decent choice.

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 Xeon E5-2440 v2 and FX-4300 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-4300 has a 1.9 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 Xeon E5-2440 v2 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 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 Xeon E5-2440 v2 and the FX-4300 have the same TDP of 95 Watts, but the Xeon E5-2440 v2 has a lower lithography size, and so will affect your yearly electricity bills less adversely.

CPU Mini Review

Mini ReviewIntel Xeon E5-2440 v2 is a Server CPU part of the Xeon E5 v2 Series released by Intel in early 2014.
It's based on the Sandy Bridge architecture and the memory controller supports DDR3-800, DDR3-1066, DDR3-1333 and DDR3-1600.
It has 8 cores and each core has 2 threads, making a total of 16. Intel Xeon E5-2440 v2 Turbo Boost is also available at 2.4GHz
The performance of this server processor is excellent.
FX-4300 is a middle-class CPU based on the 32nm Piledriver architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.8GHz, which may go up to 4.0GHz and 4MB 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.

It offers average performance. It will therefore become a bottleneck in today's demanding games.
