Will a i5 6400U bottleneck a gtx 1060 6GB?

[tjw2811]

Hey guys,

I am going to build my first pc and I am on a tight budget. I am planning on using my old laptops CPU because I am no longer going to need this laptop and will dismantle it. In my laptop, I have an
i5-6400U (yes there is a U this is not a typo) and I am planning on using this in my desktop with a gtx 1060 that my friend is giving me for a very cheap price. I was wondering whether my CPU will bottleneck a gtx 1060 or not. In conclusion, do you guys think it will bottleneck and if so should I just buy a new CPU

Thanks, guys

I have found an i5-6400 and an i5-6400t. I haven't found an i5-6400u.

Regardless....I ran a 1060 with an i7-920 which is in the ballpark with the 6400s and it ran great.

I think it will be fine.

There's an I7 6500u, or an I5 6300u.

The short answer is yes! It will bottleneck, and depending on the game may do to quite an extent.

I suspect it's a 2c/4t CPU. The base clocks will be in and around 2.5 with a lowly 3.1 - 3.4 turbo. There's your bottleneck right there. For some games it will be just fine. For anything relatively new, and any AAA games your CPU will certainly hold back that GPU. What resolution will you be gaming at? 1080p@ 60hz? The GTX1060 is a great card for that res.

The I5 'u' CPU's are older and use DDR3 ram which maxes out at 1866mhz.

By putting the GTX1060 with an average base system like that is really just holding the GPU back.

If you have a budget in mind, and a place to purchase from I can recommend something. But unless you're willing to shell out about 450 bucks as a min, you won't do that GTX1060 any justice.

You won't be able to. None of the U series chips are removable from the laptop motherboard, and if you could desolder them they would not be compatible with any desktop socket. The U us a low power chip specifically designed for laptop use.

Intel Ark clearly lists the i5 6300U (there isn't a 6400U) as a FCBGA1356, which means Ball Grid Array. Ball Grid Array devices are always soldered down to the motherboard. If you want to make use of that GTX 1060 you are going to have to build a desktop system... OR there is always "The Beast" https://www.amazon.com/XCSOURCE-External-Independent-Expresscard-AC773/dp/B0725B6L99/ref=sr_1_4?ie=UTF8&qid=1527016003&sr=8-4&keywords=external+graphics+card+for+laptops (power supply not included, results may vary, consult more websites for proper use). Unless you have a Thunderbolt 3 connection, then it gets a lot easier and you just need to buy an external graphics card enclosure... which costs a lot more than "The Beast".

There are 62xxU and 63xxU which are all 2C4T CPUs equivalent to desktop i3. The quad-core mobile i5 have the HQ suffix, not U.

Mobile chips have a different pin count (FCBGA1356) from desktop parts and are usually soldered to the motherboard, so reusing your laptop's chip is a no-go.
