In terms of overall gaming performance, the AMD Ryzen 5 2600X 6-Core 3.6GHz is massively better than the AMD Opteron 6278 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 Ryzen 5 2600X was released over three years more recently than the Opteron 6278, and so the Ryzen 5 2600X is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Opteron 6278 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 6278 has 10 more cores than the Ryzen 5 2600X. 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 Ryzen 5 2600X is more than enough for gaming purposes. However, if you intend on running a server with the Opteron 6278, 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 Ryzen 5 2600X and Opteron 6278 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 Ryzen 5 2600X 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 6278 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 Ryzen 5 2600X has a 2072 KB bigger L2 cache than the Opteron 6278, but on the other hand, it is the Opteron 6278 that has a 15984 MB bigger L3 cache than the Ryzen 5 2600X. In this case, the L2 size is probably what counts, so the Ryzen 5 2600X is likely superior 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 Ryzen 5 2600X has a 20 Watt lower Maximum TDP than the Opteron 6278, and was created with a 20 nm smaller manufacturing technology. What this means is the Ryzen 5 2600X 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 ReviewThe Ryzen 5 2600X 6-Core 3.6GHz is a mid to high-range CPU based on AMD's 12nm Zen+ microarchitecture. It offers 6 physical cores (12 logical), initially clocked at 3.6GHz, which may go up to 4.2GHz using Turbo Boost. It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. It has 16MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. It has 3MB of L2 cache, 512KB per core. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 95W. It is on par with competitor processors. Among its many features, Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. This CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC.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.
