In terms of overall gaming performance, the AMD Opteron 6276 is massively better than the Intel Xeon E5472 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 Opteron 6276 was released less than a year after the Xeon E5472, 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 Xeon E5472. 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 Xeon E5472 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 Xeon E5472 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 Xeon E5472 has a 0.7 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 Xeon E5472 has a 11288 KB bigger L2 cache than the Opteron 6276, and although the Xeon E5472 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 Xeon E5472 has a 35 Watt lower Maximum TDP than the Opteron 6276. However, the Opteron 6276 was created with a 13 nm smaller manufacturing technology. Overall, by taking both into account, the Xeon E5472 is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

CPU Mini Review

Mini ReviewThe Xeon E5472 is a brand of x86 microprocessors designed and manufactured by Intel Corporation, targeted at the non-consumer workstation, server, and embedded system markets. Primary advantages of the Xeon CPUs, when compared to the majority of Intel's desktop-grade consumer CPUs, are their multi-socket capabilities, higher core counts, and support for ECC memory.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.
