In terms of overall gaming performance, the Intel Xeon Processor X3220 is noticeably better than the AMD APU A6-5400B Dual-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 APU A6-5400B Dual-Core was released less than a year after the Xeon Processor X3220, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Xeon Processor X3220 has 2 more cores than the APU A6-5400B Dual-Core. With 4 cores, the Xeon Processor X3220 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Xeon Processor X3220 has 2 more threads than the APU A6-5400B Dual-Core. 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 Processor X3220 and APU A6-5400B 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 APU A6-5400B Dual-Core has a 1.2 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 Xeon Processor X3220 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 Xeon Processor X3220 has a 7168 KB bigger L2 cache than the APU A6-5400B Dual-Core, but neither of the CPUs have L3 caches, so the Xeon Processor X3220 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.

The APU A6-5400B Dual-Core has a 40 Watt lower Maximum TDP than the Xeon Processor X3220, and was created with a 33 nm smaller manufacturing technology. What this means is the APU A6-5400B 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 A6-5400B 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 Xeon Processor X3220, 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 ReviewThe Intel Xeon X3220 was built around the 65nm Core microarchitecture, codenamed Kentsfield. It was released in the first quarter of 2007. The Xeon 3220 has 4 physical cores clocked at 2.40 GHz, does not have a Turbo frequency and has a TDP of 105W. It has a Level 1 and Level 2 cache of 256 KB and 8192 KB respectively, and does not have a Level 3 cache. It does not integrate any Graphics Processing Units. The Xeon 3220 is a server CPU. It will run most games but it is not designed for gaming. APU A6-5400B Dual-Core is a performance CPU based on the 32nm, Piledriver architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 3.6GHz, which may go up to 3.8GHz and 1MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates weak Graphics called Radeon HD 7540D, with 192 Shader Processing Units, clocked at 760MHz, 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.
