In terms of overall gaming performance, the Intel Core i5-5300U 2.3GHz is massively better than the AMD APU A8-5557M 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 i5-5300U 2.3GHz was released over a year more recently than the APU A8-5557M Quad-Core, and so the Core i5-5300U 2.3GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The APU A8-5557M Quad-Core has 2 more cores than the Core i5-5300U 2.3GHz. With 4 cores, the APU A8-5557M 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 i5-5300U 2.3GHz and APU A8-5557M 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 Core i5-5300U 2.3GHz 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 APU A8-5557M Quad-Core has a 3584 KB bigger L2 cache than the Core i5-5300U 2.3GHz, and although the APU A8-5557M 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 i5-5300U 2.3GHz has a 20 Watt lower Maximum TDP than the APU A8-5557M Quad-Core, and was created with a 18 nm smaller manufacturing technology. What this means is the Core i5-5300U 2.3GHz 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 i5-5300U 2.3GHz and the APU A8-5557M Quad-Core both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.

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 i7-5300U 2-Core 2.3GHz is a super energy efficient mobile processor based on the 14nm, Broadwell Microarchitecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 2.3GHz, which may go up to 2.9GHz and 3MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates powerful Graphics called Intel HD Graphics 5500, with ?? Execution Units, initially clocked at 300MHz and that go up to 950MHz, 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 is a powerful processor whose performance is good. It's thus capable of running most applications smoothly without any problem.
The AMD Accelerated Processing Unit, formerly known as Fusion, is a microprocessor from AMD designed to act as a CPU and GPU solution on a single chip. Its heterogeneous system architecture has been designed to make it easier to write, optimize, and load balance software, while providing higher performance and lower power consumption.
