In terms of overall gaming performance, the AMD APU A4-3400 Dual-Core 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 APU A4-3400 Dual-Core 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 APU A4-3400 Dual-Core 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 APU A4-3400 Dual-Core may still be able to run slightly older games fairly effectively.

Both the AMD Athlon X2 7750 Black Edition and the AMD APU A4-3400 Dual-Core 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 APU A4-3400 Dual-Core 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 and the APU A4-3400 Dual-Core both have the same clock frequency, this is by no means an indicator that the two CPUs will provide the same level of performance. 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 Athlon X2 7750 and the APU A4-3400 Dual-Core have the same L2 cache size, but the APU A4-3400 Dual-Core does not appear to have an L3 cache, so the Athlon X2 7750 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 APU A4-3400 Dual-Core has a 30 Watt lower Maximum TDP than the Athlon X2 7750, and was created with a 33 nm smaller manufacturing technology. What this means is the APU A4-3400 Dual-Core 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).

The APU A4-3400 Dual-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Athlon X2 7750, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

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.
APU A4-3400 Dual-Core is an entry-level CPU based on the 32nm, Lynx architecture.

It offers 2 Physical Cores (2 Logical), clocked at 2.7GHz and 1MB of L2 Cache.

The processor integrates weak Graphics called Radeon HD 6410D, with 160 Shader Processing Units, clocked at 600MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 65W.

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