In terms of overall gaming performance, the Intel Xeon Processor E5607 is noticeably better than the AMD APU A6-7400K 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 A6-7400K Dual-Core was released over three years more recently than the Xeon Processor E5607, and so the APU A6-7400K Dual-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Xeon Processor E5607 when running the latest games.

The Xeon Processor E5607 has 2 more cores than the APU A6-7400K Dual-Core. With 4 cores, the Xeon Processor E5607 is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 A6-7400K Dual-Core and Xeon Processor E5607 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 A6-7400K Dual-Core has a 1.23 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 E5607 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 A6-7400K Dual-Core and the Xeon Processor E5607 have the same L2 cache size, but the APU A6-7400K Dual-Core does not appear to have an L3 cache, so the Xeon Processor E5607 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 A6-7400K Dual-Core has a 15 Watt lower Maximum TDP than the Xeon Processor E5607, and was created with a 4 nm smaller manufacturing technology. What this means is the APU A6-7400K Dual-Core will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The APU A6-7400K 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 E5607, 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 A8-7400K Dual-Core is a performance CPU based on the 28nm, Steamroller architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 3.5GHz, which may go up to 3.9GHz and 1MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates mildly powerful Graphics called Radeon R5 7400K, with 256 Shader Processing Units, clocked at 756MHz, 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.
Intel Xeon E5607 is a Server CPU part of the Xeon Series continuously released by Intel.
It's based on the Nehalem architecture and the memory controller supports DDR3-800 and DDR3-1066.
The performance though good, falls behind most Intel i5, i7 and since Intel Xeon E5607 wasn't built for gaming purposes it comes at a considerably high price.
