In terms of overall gaming performance, the AMD APU E1-2100 Dual Core is very slightly better than the Intel Celeron M 390 1.7GHz 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 E1-2100 Dual was released over three years more recently than the Celeron M 390, and so the APU E1-2100 Dual is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Celeron M 390 when running the latest games.

The APU E1-2100 Dual has 1 more core than the Celeron M 390. However, while the APU E1-2100 Dual will probably perform better than the Celeron M 390, both CPUs are likely to struggle with the latest games, and will almost certainly bottleneck high-end graphics cards. Both CPUs also have quite low clock frequencies, which means recent games will have to be played at low settings, assuming you own an equivalently powerful GPU.

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 E1-2100 Dual and Celeron M 390 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 Celeron M 390 has a 0.7 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 APU E1-2100 Dual.

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 E1-2100 Dual has a 1023 KB bigger L2 cache than the Celeron M 390, but neither of the CPUs have L3 caches, so the APU E1-2100 Dual wins out in this area with its larger L2 cache.

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 E1-2100 Dual has a 12 Watt lower Maximum TDP than the Celeron M 390, and was created with a 62 nm smaller manufacturing technology. What this means is the APU E1-2100 Dual 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).

CPU Mini Review

Mini ReviewAPU E1-2100 is low-entry mobile processor based on the Jaguar microarchitecture.
It offers 2 cores clocked at 1.0GHz and 1MB of Level 2 Cache. It also offers weak integrated Graphics called Radeon HD 8210G which come clocked at 300MHz and offer 128 Shader Processing Units.
Its performance is ridiculously low and so even modest games will have trouble running smoothly.
The Celeron is a family of microprocessors from Intel targeted at the low-end consumer market. CPUs in the Celeron brand have used designs from sixth- to eighth-generation CPU microarchitectures. [Please be aware that GD data is constantly refined as more information and reports are made available.]
