In terms of overall gaming performance, the AMD APU A4-5100 Quad-Core is noticeably better than the Intel Celeron 877 1.4 GHz 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 APU A4-5100 Quad-Core was released over a year more recently than the Celeron 877 1.4, and so the APU A4-5100 Quad-Core is likely to have better levels of support, and will be more optimized for running the latest games.

The APU A4-5100 Quad-Core has 2 more cores than the Celeron 877 1.4. With 4 cores, the APU A4-5100 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 APU A4-5100 Quad-Core and Celeron 877 1.4 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 A4-5100 Quad-Core has a 0.15 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 A4-5100 Quad-Core has a 1536 KB bigger L2 cache than the Celeron 877 1.4, and although the APU A4-5100 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 APU A4-5100 Quad-Core has a 2 Watt lower Maximum TDP than the Celeron 877 1.4, and was created with a 4 nm smaller manufacturing technology. What this means is the APU A4-5100 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).

CPU Mini Review

Mini ReviewAPU A4-5100 Quad-Core is a low end mobile processor based on the 28nm, Jaguar micro-architecture.
It offers 4 Cores clocked at 1.55GHz 2MB of L2 Cache. It features integrated Graphics called Radeon HD 8330G which offer 128 Shader Processing Units and perform on level with Intel HD 4000. The max memory speed supported by the CPU is DDR3-1600. It consumes up to 15 Watt.
Its performance is relatively weak and so this CPU is still a bottleneck even for performance cards such as Radeon HD 7850M/GeForce GTX 660M.
Intel Celeron 877 1.4GHz is a cheap dual-core CPU for small laptops based on the Sandy Bridge architecture but with most of its features disabled.
It features Integrated Graphics clocked at 350MHz that go up to 1000MHz in Turbo mode and the memory controller supports DDR3-1066 and DDR3-1333.
Despite its puny structure, the performance isn't as horrible as it may sound and its power consumption is extremely low.
