In terms of overall gaming performance, the AMD Athlon X2 7850 Black Edition is marginally better than the AMD Athlon X2 7750 Black Edition 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 X2 7850 was released less than a year after the Athlon X2 7750, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Athlon X2 7750 and the Athlon X2 7850 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 X2 7750 and the Athlon X2 7850 may still be able to run slightly older games fairly effectively.

Both the AMD Athlon X2 7750 Black Edition and the AMD Athlon X2 7850 Black Edition have the same number of threads. Both CPUs have one thread per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

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 X2 7750 and the Athlon X2 7850 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 0.1 GHz faster base clock rate, the Athlon X2 7850 manages to provide marginally better performance than the Athlon X2 7750.

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 X2 7750 and the Athlon X2 7850 have the same L2 cache size, and the same L3 cache size, so in terms of cache-related gaming performance, we have to look back to the clock rate, where the Athlon X2 7850 wins out.

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.

Both the Athlon X2 7750 and the Athlon X2 7850 have the same TDP of 95 Watts, and were created with the same manufacturing size of 65 nm, which means they will affect your yearly electricity bill about equally.

CPU Mini Review

Mini ReviewAthlon X2 7750 Black Edition is a middle-class processor based on the 65nm, K10 architecture.

It offers 2 Physical Cores (2 Logical), clocked at 2.7GHz and 2MB 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 95W.

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