In terms of overall gaming performance, the Intel Celeron G4900T 2-Core 2.9GHz is massively better than the AMD APU A6-9550 4-Core 3.8GHz 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 less than a year after the Celeron G4900T 2-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Celeron G4900T 2-Core and the APU A6-9550 4-Core 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 Celeron G4900T 2-Core and the APU A6-9550 4-Core may still be able to run slightly older games fairly effectively.

Both the Intel Celeron G4900T 2-Core 2.9GHz and the AMD APU A6-9550 4-Core 3.8GHz 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 Celeron G4900T 2-Core and APU A6-9550 4-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 APU A6-9550 4-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 A6-9550 4-Core has a 512 KB bigger L2 cache than the Celeron G4900T 2-Core, and although the APU A6-9550 4-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 G4900T 2-Core has a 30 Watt lower Maximum TDP than the APU A6-9550 4-Core, and was created with a 14 nm smaller manufacturing technology. What this means is the Celeron G4900T 2-Core 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).

The Celeron G4900T 2-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 APU A6-9550 4-Core, 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 ReviewThe Intel Celeron G4900T 2-Core 2.9GHz is a budget CPU based on the 14nm Coffee Lake S micro-architecture with many of its features disabled, including Turbo Boost and Hyper-Threading. It offers 2 Cores, clocked at 2.9GHz and Intel UHD 610 integrated graphics clocked at 350MHz (1000MHz in Turbo Mode) and the memory controller supports DDR4-2400. It's expected to consume up to 35 Watts and offers 2MB of L3 Cache. The gaming performance of Celeron G4900T 2-Core 2.9GHz is low-end will run games slower than a typical 7th-gen Kaby Lake-based Core i3 processor. This is not an ideal processor for modern AAA titles.The 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.
