In terms of overall gaming performance, the Intel Xeon E5-1660 v2 is massively better than the Intel Core i5-9500T 6-Core 2.2GHz 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 i5-9500T 6-Core was released over three years more recently than the Xeon E5-1660 v2, and so the Core i5-9500T 6-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Xeon E5-1660 v2 when running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Core i5-9500T 6-Core and the Xeon E5-1660 v2 both have 6 cores, which is not likely to be a limiting factor for gaming.

The Xeon E5-1660 v2 has 6 more threads than the Core i5-9500T 6-Core. The Core i5-9500T 6-Core has one thread per physical core, whereas the Xeon E5-1660 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 Core i5-9500T 6-Core and Xeon E5-1660 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 E5-1660 v2 has a 1.5 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 i5-9500T 6-Core has a 1280 KB bigger L2 cache than the Xeon E5-1660 v2, but on the other hand, it is the Xeon E5-1660 v2 that has a 3 MB bigger L3 cache than the Core i5-9500T 6-Core. In this case, the L2 size is probably what counts, so the Core i5-9500T 6-Core is likely superior 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 Core i5-9500T 6-Core has a 95 Watt lower Maximum TDP than the Xeon E5-1660 v2, and was created with a 8 nm smaller manufacturing technology. What this means is the Core i5-9500T 6-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 Core i5-9500T 6-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 E5-1660 v2, 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 Core i5-9500T 6-Core 2.2GHz is a mid-range CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. The 'T' suffix determines this CPU is a low-power variant. It offers 6 physical cores (6 logical), initially clocked at 2.2GHz, which may go up to 3.7GHz using 6 cores with Turbo Boost. The i5-9500T has 9MB of L3 Cache. This chip supports up to 128GB DDR-2666 MHz memory and features Intel UHD 630 integrated graphics. Among its many features, Turbo Boost 2.0, Optane Memory Support, and Virtualization are activated, and its multiplier is not unlocked. This Core i5-9500T CPU offers above average gaming performance and should not be the bottleneck in any modern gaming PC in 2019. It will be able to play all modern games at 60fps comfortably on ultra graphics performance at any supported resolution without being a hindrance to the accompanying GPU. However, performance may become bottlenecked if playing at 144Hz.The Intel Xeon E5-1660 v2 is a 64-bit Server CPU: part of the Xeon E5 v2 Series. It was released by Intel in late 2013.
It's based on the Ivy Bridge architecture and the memory controller supports DDR3-800, DDR3-1066, DDR3-1333, DDR3-1600 and DDR3-1866.
It has 6 cores and each core has 2 threads, make a total of 12. Turbo Boost is also available.
