In terms of overall gaming performance, the Intel Celeron G1630 2.8GHz is very slightly better than the AMD APU A4-4020 Dual-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 A4-4020 Dual-Core was released less than a year after the Celeron G1630 2.8GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The APU A4-4020 Dual-Core and the Celeron G1630 2.8GHz 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 A4-4020 Dual-Core and the Celeron G1630 2.8GHz may still be able to run slightly older games fairly effectively.

Both the AMD APU A4-4020 Dual-Core and the Intel Celeron G1630 2.8GHz 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 APU A4-4020 Dual-Core and Celeron G1630 2.8GHz 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 A4-4020 Dual-Core 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 .

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 A4-4020 Dual-Core has a 512 KB bigger L2 cache than the Celeron G1630 2.8GHz, and although the APU A4-4020 Dual-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 G1630 2.8GHz has a 10 Watt lower Maximum TDP than the APU A4-4020 Dual-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Celeron G1630 2.8GHz 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 A4-4020 Dual-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 Celeron G1630 2.8GHz, 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 ReviewAPU A4-4020 Dual-Core is an entry-level CPU based on the 32nm, Piledriver architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 3.2GHz, which may go up to 3.4GHz and 1MB of L2 Cache.
Among its many features, Turbo Core and Virtualization are activated.

The processor integrates very weak Graphics called Radeon HD 7480D, with 128 Shader Processing Units, clocked at 720MHz, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 65W.

Its performance is below the average and so most demanding games will not run optimally.
Celeron G1630 2.8GHz is a budget CPU based on the 22nm Ivy Bridge micro-architecture with many of its features disabled, including Turbo Boost and Hyper Threading.
It offers 2 Cores, clocked at 2.8GHz and integrated graphics clocked at 650MHz (1.05GHz in Turbo Mode) and the memory controller supports DDR3-1333. It's expected to consume up to 55 Watt and offers 2MB of L3 Cache.
Its gaming performance is relatively average and on level with previous Sandy Bridge based dual-core CPUs (Core i3).
