i5 6400 worth it?

post #1 of 35
Thread Starter 
Building a budget mid-tier build for my bro (UK based) - wondering if the i5 6400 will be good enough for games like fallout 4, DayZ SA, Arma III and similar?

Here's a link to the build:

Yep certainly will do! Really any modern Intel with 4 cores or more is fine for the majority of gaming.

You're going to need DDR4 RAM in there btw. Skylake supports only DDR3L on some motherboards, that's the low voltage laptop type up to 1.35 volts.

I'll look into it. some said DDR3L / DDR3. I guess you pay extra for the DDR4 which my brother doesn't care about so i'll look for a cheap and reliable ATX mobo without all the bells and whistles.

I like ASUS and this one will be available soon for £55 - https://www.asus.com/uk/Motherboards/TROOPER-H110-D3/specifications/

It's either the i5 4460 / 4440 or the i5 6400 depending on which is cheaper. currently the 6400 is, but i haven't found any worthwhile benchmarks. Thanks for the heads up guys.

If you hadnt noticed the product page for that mobo states it needs DDR3 with voltage lower then 1.5 at 1600 or 1333 mhz You can always undervolt the higher volt kit I guess, or just go with the 4460, I know initial gaming benchmarks showed Skylake suffers slightly in gaming compared to Haswell when using the slowest DDR 4 kits, I dont know if that holds true if you use DDR3 or if its purely due to the worse latency on DDR 4 at comparable MHZ to DDR 3.

Yeah i noticed it needed the lower voltages so yeah i was thinking of under-volting, but it depends whether the 4460 goes cheaper or not. I've seen b85 mobos go for £55 so i could update the bios and go for that option. will hold off for now though until i see how well the 6400 performs in gaming. Reckon it'll be fairly similar. Anyway thanks for the help man smile.gif

^^ HardOCP did some gaming benchies vs Haswell, Ivy and Sandy, there's not much difference between them but if you use the faster DDR4 kits it helps. I'd probably just go with Haswell for a bit cheaper. Its not going to be a noticeable difference IMO

I dunno about in UK but in Canada i5 44xx CPUs seem to be mainly used in OEM systems and I would stay away from those if possible as their turbo sucks with 4 cores in use--there is no turbo boost there! They have 0/1/2/2 turbo which even on 2 cores isn't much. You typically don't see them in retail stores--well I mean I'm sure they are there but they don't sell nearly as many as the i5 45xx and 46xx which have 2/3/4/4 turbo, which is better. And the price difference between them is very small, so the 44xx are a pointless buy. In the UK this may be different though.

For the Skylake i5s Intel really seem to have thrown us a loop because the turbo numbers are all over the place--6400 has 4/4/5/6 while a 6500 has 1/2/3/4 though granted it starts out at 5 higher than the 6400 at base. A 6600 then has 3/4/5/6 making it even more screwy.

Another thing is, it seems like Skylakes can be BCLK OC'd again--like you could do with Core and Nehalem, meaning the turbo on Skylakes doesn't even matter because you can just turn that off and OC manually like you could in the good ol' days! smile.gif

Did the BCLK thing make it to retail locked chips? I remember some rumours a while ago, but I've had a good look just now and I can only find this Guru 3d article saying that the non K series I7 6700 and I5 6500 dont have an unlocked bclk.

Good point on the 4590 its only about a tenner more then a 4460 on Scan thumb.gif

That article actually says the processors don't have an unlocked BCLK multiplier, which is correct wink.gif However BCLK overclocking is done by the motherboard and isn't a function of the CPU. Theoretically it's possible for the microcode to set the board in such a way to lock the BCLK adjustments on the board without a K CPU installed but I don't think they have done this--I think it is just like it was with Nehalem. The reason this can be done again is BCLK is no longer tied directly to PCIe so OCing the BCLK doesn't put other things out of spec. This is the way it was on Sandy Bridge-->Broadwell, making BCLK OCing unstable, unreliable, and effectively unusable. Locked multiplier CPUs were in effect locked completely. Now that BCLK has been "freed" again, you should be able to OC with that just as you could on first gen Core iX processors.

The board will have to have BCLK adjustments though I imagine most of the good makes/models will. I haven't done this personally of course so I can't be 100% sure, but from all the stuff I've read you are now again free to adjust the BLCK so OCing can be done on "locked" processors in that way.
