In terms of overall gaming performance, the Intel Core i7-2630QM 4-Core 2.0GHz is massively better than the Intel Celeron N2840 2.16GHz 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 three years more recently than the Core i7-2630QM 4-Core, and so the Celeron N2840 2.16GHz is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i7-2630QM 4-Core when running the latest games.

The Core i7-2630QM 4-Core has 2 more cores than the Celeron N2840 2.16GHz. With 4 cores, the Core i7-2630QM 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core i7-2630QM 4-Core has 6 more threads than the Celeron N2840 2.16GHz. The Celeron N2840 2.16GHz has one thread per physical core, whereas the Core i7-2630QM 4-Core uses hyperthreading and has 2 logical threads 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 N2840 2.16GHz and Core i7-2630QM 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 Celeron N2840 2.16GHz has a 0.16 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. As such, we need to look elsewhere for more reliable comparisons.

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 and the Core i7-2630QM 4-Core have the same L2 cache size, but the Celeron N2840 2.16GHz does not appear to have an L3 cache, so the Core i7-2630QM 4-Core definitely 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 37 Watt lower Maximum TDP than the Core i7-2630QM 4-Core, and was created with a 10 nm smaller manufacturing technology. What this means is the Celeron N2840 2.16GHz 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 N2840 2.16GHz and the Core i7-2630QM 4-Core both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.

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.
Core i7-2630QM 4-Core 2.0GHz is a high-end mobile CPU based on the 32nm, Sandy Bridge architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 2.0GHz, which may go up to 2.9GHz and 6MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor integrates relatively weak Graphics called Intel HD i7 2630QM, with 12 Execution Units, initially clocked at 650MHz and that go up to 1100MHz, 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 45W.

Its performance is very good and sufficient for any of today's games.
