In terms of overall gaming performance, the AMD APU A8-3820 Quad-Core is massively better than the Intel Core 2 Duo E7500 2.93GHz 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 A8-3820 Quad-Core was released over a year more recently than the Core 2 Duo, and so the APU A8-3820 Quad-Core is likely to have better levels of support, and will be more optimized for running the latest games.

The APU A8-3820 Quad-Core has 2 more cores than the Core 2 Duo. With 4 cores, the APU A8-3820 Quad-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The APU A8-3820 Quad-Core has 2 more threads than the Core 2 Duo. 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 APU A8-3820 Quad-Core and Core 2 Duo 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 Core 2 Duo has a 0.43 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 APU A8-3820 Quad-Core.

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 APU A8-3820 Quad-Core has a 1024 KB bigger L2 cache than the Core 2 Duo, but neither of the CPUs have L3 caches, so the APU A8-3820 Quad-Core wins out in this area with its larger L2 cache.

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 APU A8-3820 Quad-Core and the Core 2 Duo have the same TDP of 65 Watts, but the APU A8-3820 Quad-Core has a lower lithography size, and so will affect your yearly electricity bills less adversely.

The APU A8-3820 Quad-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 Core 2 Duo, 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 ReviewAPU A8-3820 Quad-Core is a performance CPU based on the 32nm, Lynx architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 2.5GHz, which may go up to 2.8GHz and 4MB of L2 Cache.

The processor integrates mildly powerful Graphics called Radeon HD 6550D, with 400 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 is a powerful Quad Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
Core 2 Duo E7500 2.93GHz is a middle-class Processor based on the 45nm Core micro-architecture.

It offers 2 Physical Cores (2 Logical), clocked at 2.93GHz and 3MB of L2 Cache.
Among its many features, Virtualization is activated.

The processor DOES NOT integrated any graphics. and has a rated board TDP of 65W.

It offers average performance. It will therefore become a bottleneck in today's demanding games.
