The Core i5-8400 is Intel's most affordable option to go beyond a quad-core setup on the desktop. With a price point of $190, it is only half the price of Core i7-8700K, but delivers nearly the same performance in games and can also compete with the Ryzen 6c12t processors thanks to its good single-threaded performance and high boost clock.

I can see the other 2 cpus being recommended as they are truly good pieces of hardware, but this one not so much.
It's a locked cpu which for some time will only be available with a Z370 board. Cheapest ones go for around $130.
On the other hand you can get a R5 1600 ($215) an pair it with a B350 board which go for as low as $60, but decent ones start at $80. You can overclock the 1600 to around 3.9G and reach 8400 in gaming and easily beat it in productivity.

So to summarize, the platform price is about the same, but AMD being 20-ish bucks cheaper. Thats $20 you could invest in a better board, ram, more storage or smth...

That's messed up, and presumably an issue that could be fixed with a BIOS update

I'm afraid intel might not want us to tell people to buy 8400s and just OC them instead of buying more expensive chips, altough you would theoretically end with around 4200Mhz max. Still...

About the review itself - i do think that the 8400 deserves better credit. This is a 185$ chip doing things like the 350$ before it did, at least in many places.

For those not interested in overclocking, definitely.

It's still gonna be the best VFM in that entire lineup, even after i3's are out.
Not if the i3's start at the same price as the current ones. 2c/4t->4c/4t is less of a jump than 4c/4t->6c/6t, but still. Obviously the real hero will be the Pentiums if they're all 2c/4t, especially if they start at the same price they do now (€50), depending a bit on their clocks.

This one looks like actual good value , though I would still pick a 1600 over it. Finally something new and worth looking into from Intel.

@W1zzard From what i see, Asrock has decided to include flexible BCLK overclocking that actually works in their boards. It seems like it is actually working, at least according to that.
Does it not work for you?

I have no such feature on my Z370 Ultra gaming board.
:(

I kinda seriously want one... It would go great with 16 gigs of ddr4 and be a nice upgrade from this aging sandy bridge system. In a year or two perhaps...

Is it possible to lock a non-K multi-core turbo boost frequency on a non-Z chipset-based motherboard, e.g. on H or B chipset? Or is it a Z-chipset feature only?
No idea

i5-8400 the best peoples' CPU. Esp if you don't wanna care about OC.
Excellent move, Intel.
