In terms of overall gaming performance, the AMD Athlon 64 X2 Dual Core BE-2450 is noticeably better than the AMD Opteron 1222 SE 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 Athlon 64 X2 was released less than a year after the Opteron 1222 SE, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Athlon 64 X2 and the Opteron 1222 SE both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the Athlon 64 X2 and the Opteron 1222 SE may still be able to run slightly older games fairly effectively.

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 Athlon 64 X2 and Opteron 1222 SE 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 Opteron 1222 SE has a 0.5 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 .

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 Athlon 64 X2 and the Opteron 1222 SE have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the Athlon 64 X2 has a 128 KB bigger L1 cache, so would probably provide better performance than the Opteron 1222 SE, at least 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 Athlon 64 X2 has a 80 Watt lower Maximum TDP than the Opteron 1222 SE, and was created with a 25 nm smaller manufacturing technology. What this means is the Athlon 64 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 ReviewAthlon 64 X2 Dual Core BE-2450 is a middle-class Processor based on the 65nm K8 micro-architecture.

It offers 2 Physical Cores (2 Logical), clocked at 2.5GHz and 1MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrated any graphics. and has a rated board TDP of 45W.

Its performance is below the average and so most demanding games will not run optimally.
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.
