In terms of overall gaming performance, the Intel Xeon E3-1220 v3 is massively better than the AMD APU A8-3800 Quad-Core 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 Xeon E3-1220 v3 was released over a year more recently than the APU A8-3800 Quad-Core, and so the Xeon E3-1220 v3 is likely to have better levels of support, and will be more optimized for running the latest games.

The Xeon E3-1220 v3 and the APU A8-3800 Quad-Core both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Xeon E3-1220 v3 and the AMD APU A8-3800 Quad-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 Xeon E3-1220 v3 and APU A8-3800 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 Xeon E3-1220 v3 has a 0.7 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 probably a good indicator that the is superior.

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 A8-3800 Quad-Core has a 3072 KB bigger L2 cache than the Xeon E3-1220 v3, and although the APU A8-3800 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 APU A8-3800 Quad-Core has a 15 Watt lower Maximum TDP than the Xeon E3-1220 v3. However, the Xeon E3-1220 v3 was created with a 10 nm smaller manufacturing technology. Overall, by taking both into account, the Xeon E3-1220 v3 is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

The APU A8-3800 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 Xeon E3-1220 v3, 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 ReviewXeon E3-1220 v3 is a Server Processor based on the 22nm, Haswell architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.1GHz, which may go up to 3.5GHz and 8MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor DOES NOT Integrate any Graphics and shares the L2 Cache and system RAM with the processor.

Though not created for gaming purposes, its performance is exceptionally good and enough for even the most demanding applications.
APU A8-3820 Quad-Core is a performance CPU based on the 32nm, Lynx architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 2.4GHz, which may go up to 2.7GHz 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 offers average performance. This means it will become a bottleneck in some demanding applications.
