In terms of overall gaming performance, the AMD Phenom II X3 710 is significantly 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 Phenom II X3 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 Phenom II X3 has 1 more core than the Athlon X2 7750. However, while the Phenom II X3 will probably perform better than the Athlon X2 7750, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. This should not affect games that are a few years old, and even the latest games should at least be playable on very low settings, as only recently have game developers begun to harness the power of multiple cores.

The Phenom II X3 has 1 more threads than the Athlon X2 7750. 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 Phenom II X3 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 Athlon X2 7750 has a 0.1 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. As such, we need to look elsewhere for more reliable comparisons.

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 X3 has a 512 KB bigger L2 cache than the Athlon X2 7750, but on the other hand, it is the Athlon X2 7750 that has a 2042 MB bigger L3 cache than the Phenom II X3. In this case, the L2 size is probably what counts, so the Phenom II X3 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.

Both the Athlon X2 7750 and the Phenom II X3 have the same TDP of 95 Watts, but the Phenom II X3 has a lower lithography size, and so will affect your yearly electricity bills less adversely.
