In terms of overall gaming performance, the AMD Phenom II X2 511 is very slightly better than the AMD Opteron 1352 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 Phenom II X2 was released over a year more recently than the Opteron 1352, and so the Phenom II X2 is likely to have better levels of support, and will be more optimized for running the latest games.

The Opteron 1352 has 2 more cores than the Phenom II X2. With 4 cores, the Opteron 1352 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Phenom II X2 and Opteron 1352 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 X2 has a 1.3 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 1352 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 Phenom II X2 and the Opteron 1352 have the same L2 cache size, but the Phenom II X2 does not appear to have an L3 cache, so the Opteron 1352 definitely 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 Phenom II X2 has a 50 Watt lower Maximum TDP than the Opteron 1352, and was created with a 20 nm smaller manufacturing technology. What this means is the Phenom II X2 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).

CPU Mini Review

Mini ReviewPhenom II X2 511 is a middle-class processor based on the 45nm, K10 architecture.

It offers 2 Physical Cores (2 Logical), clocked at 3.4GHz and 2MB of L2 Cache.
Among its many features, Virtualization is activated.

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.
Opteron is AMD's x86 server and workstation processor line, and was the first processor to implement 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 8- and 12-core Socket G34 Opterons, code-named Magny-Cours.
