How a i3-N305 (with the same N-suffix used on Celerons), is cheaper, has the double of cores and can pass out the Ryzen 5 branded CPU? TL;DR: AMD should call this CPU as a Ryzen 3.

I actually don't know why a similar release date of i3 and R5 will have that similar performance , the i3 n305 is already weaker than i3 1215u. So the I3 N305 is definitely, better πŸ‘, I've tried, performs pretty good in Roblox gaming, no lag, and it costs real cheap, like 160 usd.TRY IT

I would choose the i3 n3050 because it is cheaper in my country and has superior integrated graphics. However, it's worth noting that the 7520u does perform better in terms of single-core performance.

$300 for Intel Core i3-N3050 with 8GB/128GB and $500 for AMD Ryzen 5 7250U with 16GB/512GB. Or, just go for an Intel Core i3-1215U or AMD Ryzen 5 5500U for $300-$500. :3
