This indicates the laptop has two separate processing units, each capable of handling tasks independently. The 2.16 GHz turbo clock means one processor runs at a higher speed when needed, boosting performance. The L2 and L1 caches store frequently used data quickly, reducing delays and speeding up operations. Overall, it suggests better multitasking and faster execution of demanding applications.
Level 2 cache refers to the bigger portion of RAM built into the CPU, which I refer to as RAM because it functions similarly but is significantly quicker yet more costly per MB. Level 1 cache is quicker but has a smaller size compared to level 2. Therefore, there will be more level 2 cache available. In essence, it provides additional memory for the CPU, though it's integrated within it. Having more cache generally improves performance (even at higher levels like level 3), as demonstrated by the 7000X3D CPUs which excel in gaming.
Based on the frequencies, I'm going to guess this is an Intel Celeron N2840: https://www.intel.com/content/www/us/en/...tions.html This is a very low end mobile CPU, meaning it's performance is crap by today's standards (to be fair, it's performance was crap when it was first released also…). Otherwise, there is no sensible performance information to be gleaned from looking at raw numbers. If you are comparing two CPUs in the same generation, the one with higher frequency will generally be faster. The one with more cache can be faster, but it is situational (depends on how much a specific program benefits from more cache). When comparing cross generations, you can't go by specs alone. You can make some educated guesses, but when it comes to nuances like higher frequency vs slightly more cache, you really need to run benchmarks.
Thanks for the feedback. Your Intel Celeron N2840 has a 1 MB L2 cache, which is quite low for its age. The 10-year-old processor is indeed struggling with tasks like YouTube, so you might want to consider a newer laptop. For a budget of £200 and needs for light video editing and web browsing, look for models with at least 4-8 GB RAM, an SSD storage, and a decent display. Prioritize good battery life and portability if possible.
