Replacing a old CPU

[Barrybenkboom]

Hi,

Im very new to pc building and I have a few questions, I have a gaming PC with a kind of old cpu which i want to replace. It's a Intel i5-7400, now my question is how do i know if the new CPU will fit my current motherboard? My motherboard is a Asus H110-plus with a lga1151 socket, but i have read that there are certain cpu's from newer generations with the same socket type that wont fit my mother board, for example the Intel i5-9400f has a lga1151 socket but when I look up my motherboard every site says that it wont fit it. What do i need to look for so I know for sure that it wil work?

I have looked on there but i would like to know why only those cpu's fit, because when I look it up on different sites it will say that different cpu's fit.

Afaik they both use 1151 but 8th and 9th have to be on a 300 series chipset i.e z390 b360 so in short, the 9400f won't work on an h110 board

Only 6th and 7th gen chips will work with that board. 8th and 9th use the same physical socket, but are not compatible with the chipset and thus will not work. Intel has a list of the supported CPUs for H110 chipset: https://www.intel.com/content/www/us/en/products/sku/90590/intel-h110-chipset/compatible.html.

fitting and working are 2 different things. if they are the same socket it will fit, but when you turn the computer on it will do nothing. i looked up the supported cpu's for that motherboard and realistically there are only 2 realistic options for an upgrade anything else is  a waste. id either get an i7-6700 or an i7-7700. reason is its the most threads your mobo supports. honestly id go with the i7-6700 because its 75 dollars instead of 105 dollars and its 95 percent of the performance. The only other cpu's i would consider purchasing are the i7-6700k, or i7-7700k but they would have to be the same price or cheaper then an i7-6700 to purchase. 

TLDR: get the i7-6700 on ebay for 70 dollars and call it quits.

You can only use up to 7th gen Intel so best you could get is a 7700K, maybe around $80 to $100 used

But imo it's not a great upgrade, you'll still use slow outdated hardware, so you'd better off saving more (say $250+) and get a new board as well, and maybe faster DDR4 which is dirt cheap now

Even a 12100F ($110) will be massively better than any 7th gen...

As other people mentioned, Intel did an annoying thing where there were two versions of the LGA1151 socket which are physically identical (same number of pins in the same arrangement) but electrically different (they changed what some of the pins actually do), which means CPU's for the later version of the socket cannot go in the earlier version of the socket and vice versa.

 

The best CPU's for your board would be the i7-6700 or i7-7700. (The overclockable 6700k and 7700k aren't worth it because the H110 chipset can't overclock.)

Thank you all so much this helps me alot!

meh its worth spending 75 bucks on an i7-6700 if it gets him a few more years out of it. i just got done upgrading a buddy from an i5-3470 8gb ram and a 500 gb hard drive to an i7-3770, 16gb ram and a 500 gb ssd. elden ring runs smooth now. he was running that setup since 2017. hardware always goes down in price over long term so if this last them a couple of years slapping in a 6700 its worth it.

For a component such as a CPU to fit onto a motherboard and actually function, you need 3 things:

• Electrical compatibility: your CPU should be designed for the same socket its being put in, otherwise it simply won't fit. That means an LGA 1151 board, as you've already found out.
• Chipset compatibility: just because a CPU fits doesn't mean it'll run. Your motherboard's chipset needs to be appropriate for the model of CPU you're trying to run. The chipset is the piece of logic that holds all the hardware in your system together. Specifically, with the LGA 1151 socket, Intel designed the 100 and 200 series chipsets for 6 and 7th gen core processors (and any board of that family should be able to handle any LGA1151 CPU from those generations), with the 300 series chipsets being used for the 8th and 9th gen core processors (and again, any board using one of those chipsets should support any processor from that series). Do not try to run a 6/7th gen processor on a 300-series board or a 8/9th gen CPU on a 100/200 series board: it won't work.
• Finally, you need firmware compatibility. The first Intel 100 series boards came out in mid 2015, while the 7th gen CPUs came out  about 18 months later. To accommodate newer CPUs designed and released after a board was initially released (assuming official compatibility, as seen in the last two points), the board's firmware (called the BIOS) often needs to be updated to retroactively add support for those newer CPUs (a process which itself often requires a supported, working CPU from a previous generation).

 

You have an H110 chipset on your motherboard. Officially, that gives it support for Intel's 6th and 7th generations of CPUs, up to the Intel i7 7700K. Newer 8th and 9th gen parts are not supported here. You already have a 7th gen part installed, so the currently installed BIOS should already support any processor you can install into it without any hassle.

Unfortunately that does mean you're limited to quad-core CPUs like the 7700K though, and a platform upgrade to a newer socket and chipset will be needed for anything faster than that specific i7.

Yeah sure, I was still using a 4770k up to 2020, they are good chips

But I mean that the gain you got for 75$ on an 6th gen upgrade is quite poor compared to what you got for $200 with a 12100F and a $100 mobo

It's still old outdated tech that won't last long, whereas a 12100F will be good for next 5 years for "basic" gaming and programs

yea spending more on new platform will get him further, but will it get him twice as far for triple the money?  a 6700 is 75 bucks, the cheapest mobo,and 1200f is 180 dollars. in red dead 2 an i7-6700k (didnt see if it was OC'ed or not,)
but in red dead 2 with a rtx 3080 is 99 fps meanwhile a 12100f is 103 fps. they are very similar in their capabilities. it isnt worth the money IMHO unless you are going to something more like a 6 core chip

Sure having to upgrade board make the perf/price comparison quite unfavorable to the new platform !

And sure a 12400f would be a better investment, I went as cheap as possible

Regarding performance, 12100F is overall rather +50%  compared to 6700K in benchmarks, in games it's  quite variable from +5% in RDR2, not CPU intensive, to ...+50% in Hitman3 or BF42, which are CPU intensive (according to vid here), so it's not that "similar"

Something seems off about those numbers. Regardless even with that video all games were playable.
