In terms of overall gaming performance, the Intel Atom Z3740 1.33GHz is marginally 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 less than a year after the Atom Z3740 1.33GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Atom Z3740 1.33GHz and the APU A4 Micro-6400T both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Atom Z3740 1.33GHz and the AMD APU A4 Micro-6400T Quad-Core have the same number of threads. Both CPUs have one thread per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

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 Atom Z3740 1.33GHz and APU A4 Micro-6400T 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 Atom Z3740 1.33GHz has a 0.33 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 .

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 Atom Z3740 1.33GHz and the APU A4 Micro-6400T have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the Atom Z3740 1.33GHz has a 96 KB bigger L1 cache, so would probably provide better performance than the APU A4 Micro-6400T, at least 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 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 Atom Z3740 1.33GHz, 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 ReviewAtom is a system on chip (SoC) platform designed for smartphones and tablet computers, launched by Intel in 2012. It is a continuation of the partnership announced by Intel and Google on 13 September 2011 to provide support for the Android operating system on Intel x86 processors. This range competes with existing SoCs developed for the smartphone and tablet market from companies like Texas Instruments, Nvidia, Qualcomm and Samsung. Unlike these companies, which use ARM-based CPUs designed from the beginning to consume very low power, Intel has adapted the x86 based Atom line CPU developed for low power usage in netbooks, to even lower power usage.APU ‚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.
