In terms of overall gaming performance, the Intel Xeon E3-1230 v2 is massively better than the Intel Xeon Processor E5520 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 E3-1230 v2 was released less than a year after the Xeon Processor E5520, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Xeon Processor E5520 and the Xeon E3-1230 v2 both have 4 cores, which is not likely to be a limiting factor for gaming.

The Xeon E3-1230 v2 has 4 more threads than the Xeon Processor E5520. The Xeon Processor E5520 has one thread per physical core, whereas the Xeon E3-1230 v2 uses hyperthreading and has 2 logical threads 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 E5520 and Xeon E3-1230 v2 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 E3-1230 v2 has a 1.04 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 Xeon Processor E5520 and the Xeon E3-1230 v2 have the same L2 cache size, but the Xeon E3-1230 v2 has a 4 MB bigger L3 cache, so in this area, it wins out over the Xeon Processor E5520.

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 E3-1230 v2 has a 11 Watt lower Maximum TDP than the Xeon Processor E5520, and was created with a 23 nm smaller manufacturing technology. What this means is the Xeon E3-1230 v2 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).

CPU Mini Review

Mini ReviewXeon Processor E5520 is a Server CPU based on the 45nm, Nehalem architecture.
With most of its features activated, it offers 4 Cores (4 Logical as well), clocked at 2.26GHz, 4MB of L3 Cache and the memory controller supports DDR3-800.
Obviously not meant for gaming purposes, though its introduction price was not very high, its performance is only average, considering today's standards.
Xeon E3-1230 v2 is a Server Processor based on the 22nm, Ivy Bridge architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 3.3GHz, which may go up to 3.7GHz and 8MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor DOES NOT integrate any graphics and has a rated board TDP of 69W.

Though not created for gaming purposes, its performance is exceptionally good and enough for even the most demanding applications.
