In terms of overall gaming performance, the AMD Opteron 6276 is massively better than the AMD Athlon X4 750K 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 Athlon X4 750K was released less than a year after the Opteron 6276, and so they are likely to have similar levels of support, and similarly optimized performance when 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 Opteron 6276 has 12 more cores than the Athlon X4 750K. 16 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 Athlon X4 750K is more than enough for gaming purposes. However, if you intend on running a server with the Opteron 6276, 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 Opteron 6276 and Athlon X4 750K 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 X4 750K has a 1.1 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 Opteron 6276 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 Athlon X4 750K has a 3096 KB bigger L2 cache than the Opteron 6276, and although the Athlon X4 750K 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 X4 750K has a 15 Watt lower Maximum TDP than the Opteron 6276 (though they were created with the same size 32 nm manufacturing technology). What this means is the Athlon X4 750K will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewOpteron Hexadeca Core 6274 is a 16-Core Server CPU part of the Opteron 6200 Series released by AMD in 2011/2012.
Each Core is clocked at 2.2 and features one thread, making a total of 16.
Obviously not designed for gaming, due to its tremendous price, it will deliver great performance for those crazy enough to use for extreme gaming performance.
Athlon X4 750K is a performance processor based on the 32nm Piledriver architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.4GHz, which may go up to 4.0GHz and 4MB of L2 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 integrate any graphics. and has a rated board TDP of 100W.

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