In terms of overall gaming performance, the AMD Opteron 6124 HE is very slightly better than the AMD Phenom II X4 905e 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 6124 HE was released less than a year after the Phenom II X4, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Opteron 6124 HE has 4 more cores than the Phenom II X4. 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 Phenom II X4 is more than enough for gaming purposes. However, if you intend on running a server with the Opteron 6124 HE, 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 6124 HE and Phenom II X4 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 Phenom II X4 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 enough that it possibly indicates the superiority of the Opteron 6124 HE.

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 Phenom II X4 has a 1536 KB bigger L2 cache than the Opteron 6124 HE, but on the other hand, it is the Opteron 6124 HE that has a 12282 MB bigger L3 cache than the Phenom II X4. In this case, the L2 size is probably what counts, so the Phenom II X4 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 Phenom II X4 has a 20 Watt lower Maximum TDP than the Opteron 6124 HE (though they were created with the same size 45 nm manufacturing technology). What this means is the Phenom II X4 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 is AMD's x86 server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003 with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007 featuring a new quad-core configuration. The most-recently released Opteron CPUs are the Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively.Phenom II X4 905e is an energy efficient processor based on the 45nm, K10 architecture.

It offers 4 Physical Cores (4 Logical), clocked at 2.5GHz and 6MB of L3 Cache.
Among its many features, Virtualization is 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 65W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
