i5-4460 vs i5-6400 Skylake

[advancedmixedgaming]

I did some research and the 6400 has some perks, but I'm worried about the clock speed. Is it going to be an issue for gaming? I looked at the CPU hierarchy and it's not on there, so I would like some input. Thanks in advance.

Gaming performance will be the same on those paired with the same GPU.

Generally speaking you're not going to see more than 1-5 FPS difference between the two. I would personally recommend the i5-6400, as building on a Skylake platform will give you the most flexibility for future upgrades.

Which would you get? I want to get the Skylake just to say I have one, but I'm not too sure about clock speed. If its fine for gaming, is it fine for other processes?

Both are solid for gaming however, should you choose to go Skylake, you will also have to buy DDR4 RAMs considering you are on a DDR3 setup although there are a few mobos that support DDR3+DDR4 like the old 775 socket combo series.

 

[rolli59]

The Skylake is around 5% more efficient clock for clock so yes it is fine for all the same things.

Would it be fine if I use my DDR3 16gb (2x 8gb) 1600 RAM? It says DDR3L, so could I use my old sticks?

If you are on a tight budget go with the haswell CPU, if you have enough cash to switch to skylake go with that. you will get that satisfaction of being on the current gen platform with added room for future proofing a bit.

both will perform the same in gaming.

That would depend upon your motherboard, but probably not. Can't say for sure unless we know exactly what motherboard and RAM is being compared.

Would you be able to recommend a mobo? My ram is a Corsair XMS DDR3-1600 or 1333, not too sure. It's 16gb worth (2x 8gb sticks)

DDR3 for Skylake has to be low voltage (the L) has to be 1.35volts or less.

If it is 1.35 V DDR3, yes. Otherwise, no - it'll burn out the memory controller in the CPU.

 

[Luminary]

This would be a very good motherboard to pair with the i5-6400:

Motherboard: Asus H170-PRO ATX LGA1151 Motherboard ($110.00 @ B&H)
Total: $110.00

It's 1.5v. FML. So the only option now is to buy new RAM or go for the Haswell?

Not has to be, could be, but you could also use normal DDR3.

I'm currenly using my old DDR3 at 1.65v on a Asus z170-p D3 without any problem, the Asus have DDR3/DDR3L support, i suppose that more MBs will also have the same.

Correct will not work with Skylake.

Here's a complete listing of both motherboard and 16GB of RAM for upgrading to the i5-6400. If that's too expensive you might have to consider Haswell:


Motherboard: Asus H170-PRO ATX LGA1151 Motherboard ($110.00 @ B&H)
Memory: G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4-2400 Memory ($89.99 @ Newegg)
Total: $199.99

[Correct will not work with Skylake.

False, im using 1.65v DDR on a Asus z170-p D3

You're going to burn out your CPU.

http://www.tomshardware.com/news/skylake-memory-support,30185.html

From the article above:

"If this is the case, though, then why do OEMs such as Gigabyte support DDR3 at 1.5 V on some of their motherboards? And why do others such as Asus and ASRock support DDR3 at 1.65 V? RAM running at these voltages might be capable of operating on the motherboard without causing damage to the board itself, but again, over time it will likely damage the CPU. So if you don't have DDR3L on hand, you are probably better off to go ahead and spring for the more expensive DDR4."

 

[advancedmixedgaming]

So I saw an Asus article about their motherboards being able to handle 1.5-1.65v DDR3 with Skylake. Can I trust it? Also Juandrp is backing it up with his experience.

 

[Luminary]

I just linked the article explaining why that is a bad idea. Will work, yes, but over time your CPU be damaged as a result.

[Correct will not work with Skylake.

I will ref rephrase that Correct will not work for LONG with Skylake.

I'm a semi budget builder, I already have most of these parts (including the RAM, PSU, Monitor, and HDD)
Would I be better off going Haswell?

 

[rolli59]

I selected a Skylake build when upgrading myself with DDR4 ram. If I had planned on reusing my DDR3 I would have selected Haswell.
