In terms of overall gaming performance, the AMD APU A6-5400B Dual-Core is marginally better than the Intel Celeron G1620 2.7GHz 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 Celeron G1620 2.7GHz was released less than a year after the APU A6-5400B Dual-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The APU A6-5400B Dual-Core and the Celeron G1620 2.7GHz both have 2 cores, and so are quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running them. With a decent accompanying GPU, the APU A6-5400B Dual-Core and the Celeron G1620 2.7GHz may still be able to run slightly older games fairly effectively.

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 A6-5400B Dual-Core and Celeron G1620 2.7GHz 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 A6-5400B Dual-Core has a 0.9 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 probably a good indicator that the is superior.

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 A6-5400B Dual-Core has a 512 KB bigger L2 cache than the Celeron G1620 2.7GHz, and although the APU A6-5400B Dual-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 Celeron G1620 2.7GHz has a 10 Watt lower Maximum TDP than the APU A6-5400B Dual-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Celeron G1620 2.7GHz 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 A6-5400B Dual-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 Celeron G1620 2.7GHz, 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 ReviewAPU A6-5400B Dual-Core is a performance CPU based on the 32nm, Piledriver architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 3.6GHz, which may go up to 3.8GHz and 1MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates weak Graphics called Radeon HD 7540D, with 192 Shader Processing Units, clocked at 760MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 65W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
Celeron G1620 2.7GHz is a budget CPU based on the 22nm Ivy Bridge micro-architecture with many of its features disabled, including Turbo Boost and Hyper Threading.
It offers 2 Cores, clocked at 2.7GHz and integrated graphics clocked at 650MHz (1.05GHz in Turbo Mode) and the memory controller supports DDR3-1333. It's expected to consume up to 55 Watt and offers 2MB of L3 Cache.
Its gaming performance is relatively average and on level with previous Sandy Bridge based dual-core CPUs (Core i3).
