Shameless bump for a chap that find the thread.

What is going on with the 8400? Seems like there is zero reason to buy anything else according to some of these reviews. Something seems very odd.

Its just capable of maxxing out the 1080ti. We'll see a gap appear with faster GPU's
The 8400 does look to be a bit of a bargain tbh.

I think we're seeing the limits of the ring bus scaling.

Scougar · 8 Oct 2017 at 03:16

What confuses me here is isn't the 8700k clocked much higher than the 8400. An architectural limit would make sense, but they will kill there own chip sales. I am doubting the ring bus though as otherwise surely over clocking would not yield an improvement?

Deliberate move perhaps?

I wonder where my 4690K at 4.5 Ghz would come in on that graph...

Any comparison to the 8400 and the 8600k?

updated video review from Jay after finding out about the MCE thing.

Hardware Unboxed review - i5-8400

Hardware Unboxed review - i5-8400

Good review. Basically confirms what we've already seen - buy a 1600 if you do a lot of multi-tasking and some gaming, buy an 8400 for pure gaming. Although often it isn't quite that clear cut due to RAM speed and component cost.

Indeed, I've been waiting for this review.

Worth noting at the end, using the ASRock Z370 Taichi no BCLK overclocking, locked out at 102MHz and can not max the boost to 4GHz with enhanced cores so 3.8GHz max, they tried MSI, Gigabyte boards as well.

Even at 3.8ghz performance is good for the price. One area that the 8400 falls down in reviews is the pricing, in this review and another from a NZ reviewer, they thought the 8400's total cost was too high. Fortunately, in the UK there is only a very small difference in price.

I do wish he went into more detail about the benefits of fast RAM that would only be available on Z370; there are some good gains to be made from 2400mhz to 3200mhz.

The uploader of the video below says "As requested were facing of my intel i5 8400 and ryzen 1600, the 8400 is running with mce" and that's with an ASUS Prime Z370-A. So maybe it's board dependent, or the Asus board is wrong.

8400 doing very well in these gaming tests.

Yeah seems very reasonable in terms of pricing, just get the cheapest Z370 board seen as any form of clocking is locked, I think cache can still be done though. OcUK have a couple of boards at £109.99

I was just watching another video from earlier in the year with 'Kaby Lake DDR4 Memory Guide, Scaling Performance Tested' from January 2017, then noticed this video pop up as new.

Hopefully they do another one soon for Coffee Lake and Ryzen refresh, here's the Kabylake one anyway just for reference if anyone is interested >> https://www.youtube.com/watch?v=fhc4blOJZeA

Tech Deals also noted in the 8700K review that windows feels more snappier than his Ryzen systems, and in the comments he's already mentioned that he thinks for gaming i5-8400 is better than Ryzen 1600 for gaming anyway.

CAT-THE-FIFTH · 13 Oct 2017 at 01:59

Added the Hardware Unboxed video to the OP and once they publish it on Techspot will add that in!

The latter test is a bit unrealistic as 2133mhz is very slow RAM, 2400mhz is more common.
