In terms of overall gaming performance, the Intel Celeron N2840 2.16GHz is marginally better than the Intel Celeron Dual-Core 867 1.3GHz 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 N2840 2.16GHz was released over a year more recently than the Celeron Dual-Core 867, and so the Celeron N2840 2.16GHz is likely to have better levels of support, and will be more optimized for running the latest games.

The Celeron N2840 2.16GHz and the Celeron Dual-Core 867 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 N2840 2.16GHz and the Celeron Dual-Core 867 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 N2840 2.16GHz and Celeron Dual-Core 867 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 N2840 2.16GHz has a 0.86 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 Celeron N2840 2.16GHz has a 512 KB bigger L2 cache than the Celeron Dual-Core 867, and although the Celeron N2840 2.16GHz 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 N2840 2.16GHz has a 9 Watt lower Maximum TDP than the Celeron Dual-Core 867, and was created with a 10 nm smaller manufacturing technology. What this means is the Celeron N2840 2.16GHz 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 Celeron N2840 2.16GHz 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 Dual-Core 867, 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 ReviewCeleron N2840 2.16GHz is a Budget Mobile Processor based on the 22nm, Silvermont Architecture.

It offers 2 Physical Cores (2 Logical), initially clocked at 2.16GHz, which may go up to 2.58GHz and 1MB of L2 Cache.
Among its many features, Burst Performance and Virtualization are activated.

The processor integrates Very Weak Graphics called Intel HD Mobile (Bay Trail), with 4 Shader Processing Units, clocked at 311MHz, which go up to 792MHz, in Turbo Mode, which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 7.5W.

Benchmarks indicate its performance is just about as good as AMD's A4-4xxx Processors.
Sandy 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.
