In terms of overall gaming performance, the AMD APU A6-9550 4-Core 3.8GHz is massively better than the Intel Atom S1220 1.6GHz 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 A6-9550 4-Core was released over three years more recently than the Atom S1220 1.6GHz, and so the APU A6-9550 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Atom S1220 1.6GHz when running the latest games.

The APU A6-9550 4-Core and the Atom S1220 1.6GHz 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 A6-9550 4-Core and the Atom S1220 1.6GHz 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 A6-9550 4-Core and Atom S1220 1.6GHz 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 A6-9550 4-Core has a 2.2 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 A6-9550 4-Core and the Atom S1220 1.6GHz have the same L2 cache size, and neither CPU appears to have an L3 cache. In this case, the APU A6-9550 4-Core has a 48 KB bigger L1 cache, so would probably provide better performance than the Atom S1220 1.6GHz, 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 Atom S1220 1.6GHz has a 57 Watt lower Maximum TDP than the APU A6-9550 4-Core. However, the APU A6-9550 4-Core was created with a 4 nm smaller manufacturing technology. Overall, by taking both into account, the Atom S1220 1.6GHz is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewThe AMD APU A6-9550 4-Core 3.8GHz is a budget APU based on AMD's 28nm Excavator microarchitecture. It offers 4 physical cores (4 logical) initially clocked at 3.8GHz, rising to 4.0GHz in boost mode. It has an unlocked multiplier and therefore can overclocked using traditional methods. It has 1MB of L2 Cache. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 65W, making it an averagely power efficient CPU. Among its many features are Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. The APU A6-9550 4-Core 3.8GHz features integrated Radeon R5 3rd Gen GCN graphics with 384 Shaders and a base clock speed of 1,029MHz. This is a low-end graphics chip that will struggle to run any modern game at 720p.Atom S1220 is a budget Server CPU based on the Centerton Core of the 32nm Saltwell micro-architecture.
Manufactured with a 32nm technology, it features 2 Cores (4 Threads) clocked at 1.6GHz and no Integrated Graphics. The Memory controller supports up to DDR3-1333 memory type. The Max power drawn should be of around 8W.
Its performance is overall average but there are no benchmarks available and so this CPU's rank is subject to change.
