Gaming Performance Comparison
In terms of overall gaming performance, the AMD APU A10-5757M Quad-Core is significantly better than the AMD APU A8-5545M 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.
Both the APU A10-5757M Quad-Core and the APU A8-5545M Quad-Core were released at the same time, so are likely to be quite similar.
The APU A10-5757M Quad-Core and the APU A8-5545M Quad-Core both have 4 cores, which is not likely to be a limiting factor for gaming.
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 APU A10-5757M Quad-Core and the APU A8-5545M Quad-Core are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 0.8 GHz faster base clock rate, the APU A10-5757M Quad-Core manages to provide significantly better performance than the APU A8-5545M 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 A10-5757M Quad-Core and the APU A8-5545M Quad-Core have the same L2 cache size, and neither CPU appears to have an L3 cache. They even have the same L1 cache size, so are identical in terms of cache size.
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 APU A8-5545M Quad-Core has a 16 Watt lower Maximum TDP than the APU A10-5757M Quad-Core (though they were created with the same size 32 nm manufacturing technology). What this means is the APU A8-5545M Quad-Core 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 APU A10-5757M Quad-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 APU A8-5545M 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||AMD A10-5757M is a mobile Quad Core processor, part of AMD's APU processors based on Richland, and thus fabricated using a 32nm technology. It sports four cores, clocked at 2.5GHz, and reaching 3.5GHz in Turbo Mode. This APU features the Radeon HD 8650G, clocked at 600MHz, which goes up to 720Mhz when Turbo is enabled. It supports DDR3-1600MHz RAM, and its thermal design power is only 35 watts. Compared to A10-5750M, this processor's onboard GPU is clocked at a higher base frequency, however the maximum memmory supported drops from 1866Mhz to 1600MHz.||APU A8-5545M Quad-Core is an ULV processor based on the 32nm, Richland micro-architecture. |
It offers 4 Cores, initially clocked at 1.7GHz that go up to 2.7GHz, in Turbo Mode and 4MB of L2 Cache. It features integrated Graphics called Radeon HD 8510G offers 256 Shader Processing Units and are substantially faster than previous Radeon HD 7520G. The max memory speed supported by the CPU is DDR3-1333. It consumes up to 195 Watt.
This CPU should only be paired with middle-class Graphics Cards such as Radeon HD 7670M/GT 630M.
