In terms of overall gaming performance, the Intel Core i5-4590T 2.0GHz is massively better than the Intel Celeron G550T 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 i5-4590T 2.0GHz was released over a year more recently than the Celeron G550T 2.2GHz, and so the Core i5-4590T 2.0GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The Core i5-4590T 2.0GHz has 2 more cores than the Celeron G550T 2.2GHz. With 4 cores, the Core i5-4590T 2.0GHz is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core i5-4590T 2.0GHz has 2 more threads than the Celeron G550T 2.2GHz. Both CPUs have one thread 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 i5-4590T 2.0GHz and Celeron G550T 2.2GHz 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 Celeron G550T 2.2GHz has a 0.2 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. As such, we need to look elsewhere for more reliable comparisons.

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 i5-4590T 2.0GHz has a 512 KB bigger L2 cache than the Celeron G550T 2.2GHz, 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.

Both the Core i5-4590T 2.0GHz and the Celeron G550T 2.2GHz have the same TDP of 35 Watts, but the Core i5-4590T 2.0GHz has a lower lithography size, and so will affect your yearly electricity bills less adversely.

The Core i5-4590T 2.0GHz 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 Celeron G550T 2.2GHz, 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 i5-4590T 2.0GHz is a super energy efficient CPU based on the 22nm, Haswell architecture.

It offers 4 Physical Cores (4 Logical), initially clocked at 2.0GHz, which may go up to 3.0GHz and 6MB of L3 Cache.
Among its many features, Turbo Boost and Virtualization are activated.

The processor integrates powerful Graphics called Intel HD Graphics 4600, with 20 Execution Units, initially clocked at 350MHz and that go up to 1150MHz, 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 65W.

Its performance is very good and sufficient for extreme gaming.
Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.
