In terms of overall gaming performance, the Intel Core i5-4690K 3.5GHz is massively better than the Intel Xeon Processor E5620 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 Core i5-4690K 3.5GHz was released over three years more recently than the Xeon Processor E5620, and so the Core i5-4690K 3.5GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Xeon Processor E5620 when running the latest games.

The Core i5-4690K 3.5GHz and the Xeon Processor E5620 both have 4 cores, which is not likely to be a limiting factor for gaming.

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 Core i5-4690K 3.5GHz and Xeon Processor E5620 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 i5-4690K 3.5GHz has a 1.1 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 Core i5-4690K 3.5GHz and the Xeon Processor E5620 have the same L2 cache size, but the Xeon Processor E5620 has a 6 MB bigger L3 cache, so in this area, it wins out over the Core i5-4690K 3.5GHz.

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 Xeon Processor E5620 has a 8 Watt lower Maximum TDP than the Core i5-4690K 3.5GHz. However, the Core i5-4690K 3.5GHz was created with a 10 nm smaller manufacturing technology. Overall, by taking both into account, the Core i5-4690K 3.5GHz is likely the CPU with the lower heat production and power requirements, by a small amount.

The Core i5-4690K 3.5GHz 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 E5620, 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 ReviewCore i5-4690K 3.5GHz is a performance CPU based on the 22nm, Haswell architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 3.5GHz, which may go up to 3.9GHz and 6MB of L3 Cache.
Among its many features, Turbo Boost and Virtualization are activated and the processor has multiplier unlocked.

The processor integrates powerful Graphics called Intel HD Graphics 4600, with 20 Execution Units, initially clocked at 350MHz and that go up to 1200MHz, 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 88W.

Compared to Core i5-4670K there's an overall 3% performance boost. Its performance is exceptionally good and enough for even the most demanding applications.
Intel Xeon E5620 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 E5620 wasn't built for gaming purposes it comes at a considerably high price.
