In terms of overall gaming performance, the Intel Core i5-4200U 1.6GHz is significantly better than the AMD APU A8-5550M Quad-Core 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 i5-4200U 1.6GHz was released over a year more recently than the APU A8-5550M Quad-Core, and so the Core i5-4200U 1.6GHz is likely to have better levels of support, and will be more optimized for running the latest games.
The APU A8-5550M Quad-Core has 2 more cores than the Core i5-4200U 1.6GHz. With 4 cores, the APU A8-5550M Quad-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.
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 i5-4200U 1.6GHz and APU A8-5550M Quad-Core 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 APU A8-5550M Quad-Core has a 0.5 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 enough that it possibly indicates the superiority of the APU A8-5550M Quad-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 APU A8-5550M Quad-Core has a 3584 KB bigger L2 cache than the Core i5-4200U 1.6GHz, and although the APU A8-5550M Quad-Core does not appear to have an L3 cache, its larger L2 cache means that it wins out 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 i5-4200U 1.6GHz has a 20 Watt lower Maximum TDP than the APU A8-5550M Quad-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Core i5-4200U 1.6GHz 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).
The Core i5-4200U 1.6GHz 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 APU A8-5550M Quad-Core, 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.

|Mini Review||Core i5-4200U 1.6GHz is a super energy efficient mobile processor based on the 22nm, Haswell architecture. |
It offers 2 Physical Cores (4 Logical), initially clocked at 1.6GHz, which may go up to 2.6GHz and 3MB of L3 Cache.
Among its many features, Turbo Boost and Virtualization are activated.
The processor integrates mildly powerful Graphics called Intel HD i5 4200U (variant of Intel HD Graphics 4400), with 20 Execution Units, initially clocked at 200MHz and that go up to 1000MHz, 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 15W.
It offers average performance. This means it will become a bottleneck in some demanding applications.
|APU A8-5550M Quad-Core is a fast-middle-class mobile processor based on the 32nm, Richland micro-architecture. |
It offers 4 Cores, initially clocked at 2.1GHz that go up to 3.1GHz, in Turbo Mode and 4MB of L2 Cache. It features integrated Graphics called Radeon HD 8550G which offer 256 Shader Processing Units and are substantially faster than previous Radeon HD 7640G. The max memory speed supported by the CPU is DDR3-1600. It consumes up to 35 Watt.
This CPU should only be paired with performance GPUs such as Radeon HD 7850M/GeForce GTX 660M.
