CPUs in the Celeron brand have used designs from sixth- to eighth-generation CPU microarchitectures.
![]() 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 and the Core i5-540UM 1.2GHz 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 Core i5-540UM 1.2GHz may still be able to run slightly older games fairly effectively. The Core i5-540UM 1.2GHz has 2 more threads than the Celeron N2840 2.16GHz. The Celeron N2840 2.16GHz has one thread per physical core, whereas the Core i5-540UM 1.2GHz 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. ![]() Bear in mind, then, that while the Celeron N2840 2.16GHz has a 0.96 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 Core i5-540UM 1.2GHz, 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 10 Watt lower Maximum TDP than the Core i5-540UM 1.2GHz, 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.
