In terms of overall gaming performance, the Intel Core i5-8400T 6-Core 1.7GHz is massively better than the Intel Xeon Processor E5607 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 i5-8400T 6-Core was released over three years more recently than the Xeon Processor E5607, and so the Core i5-8400T 6-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 Core i5-8400T 6-Core has 2 more cores than the Xeon Processor E5607. 6 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the Xeon Processor E5607 is more than enough for gaming purposes.

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 i5-8400T 6-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 Xeon Processor E5607 has a 0.57 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 enough that it possibly indicates the superiority of the Core i5-8400T 6-Core.

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 i5-8400T 6-Core has a 512 KB bigger L2 cache than the Xeon Processor E5607, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 i5-8400T 6-Core has a 45 Watt lower Maximum TDP than the Xeon Processor E5607, and was created with a 18 nm smaller manufacturing technology. What this means is the Core i5-8400T 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 i5-8400T 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 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 ReviewThe Intel Core i5-8400T 6-Core 1.7GHz is a low to mid-range power-efficient CPU based on Intel's 8th Gen 14nm Coffee Lake S microarchitecture. It offers 6 physical cores (6 logical), initially clocked at 1.7GHz across all six cores, rising to a maximum of 3.3GHz with Turbo Boost 2.0 enabled. The i5-8400T does not have an unlocked multiplier and therefore cannot be overclocked using traditional methods. It has 9MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. The Core i3-8300T has support for up to 64GB of dual-channel DDR4-2400 memory. It has a maximum Thermal Power Design of 35W, making it a very power efficient processor. Among its many features are Intel Enhanced Speedstep, Turbo Boost 2.0, Virtualization, SSE3, AVX2 and SSE 4.2. This CPU is likely to offer average computational performance and could become a bottleneck in some of the most CPU-intensive AAA games from 2020 onward.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.
