In terms of overall gaming performance, the AMD Athlon II X2 260 is marginally better than the AMD Athlon II X2 245e 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.

Both the Athlon II X2 245e and the Athlon II X2 260 were released at the same time, so are likely to be quite similar.

The X2 245e and the X2 260 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 X2 245e and the X2 260 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 X2 245e and the X2 260 are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.3 GHz faster base clock rate, the X2 260 manages to provide slightly better performance than the X2 245e.

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 X2 245e and the X2 260 have the same L2 cache size, and neither CPU appears to have an L3 cache. They even have the same L1 cache size, so are identical in terms of cache size.

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 X2 245e has a 20 Watt lower Maximum TDP than the X2 260 (though they were created with the same size 45 nm manufacturing technology). What this means is the X2 245e 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 Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache. There are two Athlon II dies: the dual-core Regor die with 1 MB L2 Cache per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP and additional L2 to offset the removal of L3 cache. The three core Rana is derived from the Propus quad-core design, with one core disabled.The Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series.
