In terms of overall gaming performance, the Intel Core i3-2365M 1.4GHz is very slightly better than the AMD APU A4 Micro-6400T 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 APU A4 Micro-6400T was released over a year more recently than the Core i3-2365M 1.4GHz, and so the APU A4 Micro-6400T is likely to have better levels of support, and will be more optimized for running the latest games.

The APU A4 Micro-6400T has 2 more cores than the Core i3-2365M 1.4GHz. With 4 cores, the APU A4 Micro-6400T 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 Micro-6400T and Core i3-2365M 1.4GHz 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 i3-2365M 1.4GHz has a 0.4 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 A4 Micro-6400T.

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 Micro-6400T has a 1536 KB bigger L2 cache than the Core i3-2365M 1.4GHz, and although the APU A4 Micro-6400T 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 Micro-6400T has a 13 Watt lower Maximum TDP than the Core i3-2365M 1.4GHz, and was created with a 4 nm smaller manufacturing technology. What this means is the APU A4 Micro-6400T 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 A4 Micro-6400T and the Core i3-2365M 1.4GHz 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 ReviewAPU ‚ÄčA4 Micro-6400T Quad-Core is a micro mobile processor based on the 28nm, Puma+ microarchitecture, exclusively for tablets.
It offers 4 cores clocked at 1.0GHz that go up to 1.6GHz, in Turbo Mode and 2MB of Level 2 Cache. It also offers weak integrated Graphics called Radeon R3 6400T which come clocked at 350MHz and offer 128 Shader Processing Units.
Its performance is ridiculously low and thus only suited for home browsing.
Core i3-2365M 1.4GHz is an ULV mobile processor based on the 32nm Sandy Bridge architecture with most of the Sandy Bridge features activated - not Turbo Boost, for example, that's optimized for low power consumption.
It features 2 Cores (4 Threads), clocked at 1.4GHz and integrated graphics called Intel HD 3000 which run at 350MHz (1000 MHz in Turbo mode). The CPU supports DDR3-1066 and DDR3-133 memory types. Expect a TDP of up to 17 Watt.
Its gaming performance is below the average, considering today's standards and so it should only be paired with middle to fast-middle-class GPUs such as GeForce GT 540M/GeForce GT 630M & Radeon HD 6650M/7650M. Its graphics performance is also substancialy lower.
