In terms of overall gaming performance, the Intel Pentium Dual Core 3550M 2.3GHz is significantly better than the Intel Atom x5-Z8300 1.44GHz 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 Pentium Dual Core was released less than a year after the Atom x5-Z8300 1.44GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Atom x5-Z8300 1.44GHz has 2 more cores than the Pentium Dual Core. With 4 cores, the Atom x5-Z8300 1.44GHz 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 Atom x5-Z8300 1.44GHz and Pentium Dual Core 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 Pentium Dual Core has a 2.3 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 Atom x5-Z8300 1.44GHz 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 Atom x5-Z8300 1.44GHz has a 1024 KB bigger L2 cache than the Pentium Dual Core, and although the Atom x5-Z8300 1.44GHz 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 Atom x5-Z8300 1.44GHz has a 35 Watt lower Maximum TDP than the Pentium Dual Core, and was created with a 8 nm smaller manufacturing technology. What this means is the Atom x5-Z8300 1.44GHz will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewAtom x5-Z8300 4-Core 1.44GHz is a power efficient mobile/tablets CPU based on the 14nm, Cherry Trail architecture. It offers 4 Physical Cores (4 Logical), initially clocked at 1.44GHz, which may go up to 1.84GHz and 2MB of L2 Cache. Among its features, Virtualization and Secure Boot are activated. The processor integrates Graphics called Intel HD Graphics (Cherry Trail), initially clocked at 200MHz and that go up to 500MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor. Both the processor and integrated graphics have a rated board TDP of just 2W. Its performance is below average and sufficient for office or school work or non-demanding games and even those with significantly reduced settings. Pentium Dual Core 3550M 2.3GHz is a budget processor, part of the Haswell Refresh CPUs released in April of 2014.
Based on 22nm architecture, the Pentium Dual Core 3550M 2.3GHz has many of the Haswell features disabled, including Hyper and Multi Treading. The Processor should not consume more than 37 Watts.
This CPU is clocked at 2.3GHz and comes with a weak Intel HD (Haswell) mobile chip which raises to 1100MHz in Turbo Mode and will only be seen in smaller cheaper notebooks.
Its performance is average and will only provide modest gaming though most modern demanding games will run fluently.
