The 10400F might be better for your money but. What people don't see because of all sources only caring about benchmarking games but what about editing, streaming, and gaming. The 10400 is better for pretty much everything but cost a couple bucks more because the 10400F is only decent for gaming and if you wanna get something only for gaming get a newer and better CPU.

Both are good because you will use a GPU for graphic design.

mike, 10400f and 10400 are the same processor. Its just that the 10400f does not have intergrated graphics. I'd recommend 10400f for same performance for less money.

So if both can be had for the same price do you go with the 10400 over the 10400f? Is there a disadvantage to gaming with the 10400?

For only gaming targets i5 10400F is good choice but if you are going to stream, edit videos and such on i5 10400 would do better

Billy Riz i5-1400 is better for multi core operations (streaming plus gaming) but if you only care about gaming and some side stuff then the i5-10400f is the better choice.

If you are gonna buy a graphics card, then i5 10400F should be your choice cause you are not gonna need integrated graphics. there is almost no difference in performance. if you dont wanna buy a gpu right now (considering the high prices or maybe you just don't need one) you can take the 10400 with integrated graphics. thats it as easy as that. no need to check out all these comparisons. Both are the same but one needs a gpu.

Is the i5 10400f overclockable, and does it only support two memory Chanels or can I use all four

Hi! 1. 10400f is overclockable 2. You can use 4 memory slots (if your motherboard has all 4 slots) but it will works only in dual channels mode.

Root, 10400f is NOT OVERCLOCKABLE! I own this CPU and certainly wouldn't allow me to overclock.
