Hi, I have recently bought an i5 12400F. I can refund it and add 40$ to get the i5 13400F. I play games like Fortnite and Valorant on low graphics. Is this all worth it? I have an RTX 3060 as GPU. Thanks for the replies.

Not worth it, a single core is just 5% different, and 12400f is more energy efficient. Fortnite or valorant cant use many cores, I'm using 12400f and 6700xt now very satisfied with the performance.

From what I read, the major differences in 13400f are: 1) 13400f has 4 Efficiency Cores (EC) which makes a total of 10 cores, meanwhile, the 12400f doesn't have EC. More cores usually build more heat and draw more power. 2) 13400f max turbo frequency reached up to 4.6 GHz, meanwhile 12400f can only reach 4.4 GHz. 3) The L2 cache in 13400f is also 2 MB bigger than 12400f. On paper, the 13400f is more powerful than the 12400f but the real testing results can be different. I think we have to wait until the 13400f gets the full review because it's still very new. If the price-to-performance ratio is not that good and is not much better than the 12400f, probably you don't have to upgrade to 13400f yet.
