In terms of overall gaming performance, the Intel Celeron Dual-Core 867 1.3GHz is noticeably better than the Intel Atom N2800 1.86GHz 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 Celeron Dual-Core 867 was released less than a year after the Atom N2800 1.86GHz, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Celeron Dual-Core 867 and the Atom N2800 1.86GHz 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 Dual-Core 867 and the Atom N2800 1.86GHz 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 Celeron Dual-Core 867 and Atom N2800 1.86GHz 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 Atom N2800 1.86GHz has a 0.56 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 Atom N2800 1.86GHz has a 512 KB bigger L2 cache than the Celeron Dual-Core 867, and although the Atom N2800 1.86GHz 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 N2800 1.86GHz has a 10 Watt lower Maximum TDP than the Celeron Dual-Core 867 (though they were created with the same size 32 nm manufacturing technology). What this means is the Atom N2800 1.86GHz 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 ReviewSandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.Atom N2800 is an entry-level dual-core CPU part of the Atom Series continually released by Intel.
It's based on the Saltwell architecture and has 2 threads per core, making a total of 4. Each core is clocked at 1.86GHz and the memory controller only supports DDR3-1066 memory.
Despite its 4 threads Atom N2800's performance is surprisingly bad. However, Atom N2800's is only for tablets and netbooks. Atom N2800 also features integrated graphics clocked 640MHz. The power consumption is very low and only up to 6.5W according to Intel.
