In terms of overall gaming performance, the AMD Opteron 6276 is massively better than the AMD APU A8-6500B Quad-Core 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 APU A8-6500B Quad-Core 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 APU A8-6500B Quad-Core. 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 APU A8-6500B Quad-Core 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 APU A8-6500B Quad-Core and Opteron 6276 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 APU A8-6500B Quad-Core has a 1.2 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 APU A8-6500B Quad-Core has a 3096 KB bigger L2 cache than the Opteron 6276, and although the APU A8-6500B Quad-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 APU A8-6500B Quad-Core has a 50 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 APU A8-6500B Quad-Core will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The APU A8-6500B Quad-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Opteron 6276, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewAPU A8-6500B Quad-Core is a performance CPU based on the 32nm, Piledriver architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.5GHz, which may go up to 4.1GHz and 4MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates mildly powerful Graphics called Radeon HD 7560D, with 256 Shader Processing Units, clocked at 760MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 65W.

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