In terms of overall gaming performance, the AMD APU A8-3870K Quad-Core is massively better than the Intel Pentium G3220 3.0GHz 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 Pentium G3220 3.0GHz was released over a year more recently than the APU A8-3870K Quad-Core, and so the Pentium G3220 3.0GHz is likely to have better levels of support, and will be more optimized for running the latest games.
The APU A8-3870K Quad-Core has 2 more cores than the Pentium G3220 3.0GHz. With 4 cores, the APU A8-3870K Quad-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.
The APU A8-3870K Quad-Core has 2 more threads than the Pentium G3220 3.0GHz. 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 Pentium G3220 3.0GHz and APU A8-3870K Quad-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 Pentium G3220 3.0GHz and the APU A8-3870K Quad-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 APU A8-3870K Quad-Core has a 3584 KB bigger L2 cache than the Pentium G3220 3.0GHz, and although the APU A8-3870K Quad-Core does not appear to have an L3 cache, its larger L2 cache means that it 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 Pentium G3220 3.0GHz has a 46 Watt lower Maximum TDP than the APU A8-3870K Quad-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Pentium G3220 3.0GHz 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 Pentium G3220 3.0GHz and the APU A8-3870K Quad-Core both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.
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.

|Mini Review||Pentium G3220 3.0GHz is a budget processor based on the 22nm, Haswell architecture. |
It offers 2 Physical Cores (2 Logical), clocked at 3.0GHz and 3MB of L3 Cache.
Among its many features, Virtualization is activated.
The processor integrates very weak Graphics called Intel HD Graphics Desktop (Haswell), with 10 Execution Units, initially clocked at 350MHz and that go up to 1100MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 54W.
It offers average performance. This means it will become a bottleneck in some demanding applications.
|APU A8-3870K Quad-Core is a performance CPU based on the 32nm, Lynx architecture. |
It offers 4 Physical Cores (4 Logical), clocked at 3.0GHz and 4MB of L2 Cache.
Among its many features, Virtualization is activated and the processor has the clock multiplier unlocked, meaning it can be overclocked easily.
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 100W.
It is a powerful Quad Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
