Intel Haswell i5-4670K vs. i7-4770K Comparison

[FreedomEclipse]

The sound card is Creative SB Live! 24 bit.

Bingo. the SB Live is a real old card and it probably struggles with proper HD audio

Ive managed to run 1080 on a laptop thats older and much slower then your PC and It still managed watching full 1080p blu-ray rips just fine with 2GB DDR2, Intel T2300 & X1600MR but the drivers for the X1600 were broken so windows wouldnt use it for hardware acceleration anymore and all the processing was dumped onto the CPU. It didnt 5.1 surround sound or a dedicated soundcard but it did all right.

I purchased a Broadcom Crystal HD decoder card from ebay to offload some of the HD encoding off my CPU and it worked a treat till i eventually decided it was time to sell the laptop.

the Broadcom Crystal HD is a decoder card which helps decode HD video streams meaning you can watch full 1080p on even the weakest intel Atom powered netbook out of the bargain bucket.

It dropped my CPU usage down from constant 70-80% usage on both cores to about 25-30% while watching blu-ray rips.

Probably. Could be the bottlenecked gpu as well. But the thing is, 720p works just great.

Still don't understand my delidded 4670K (with MX-4) with Asrock Z87 Extreme 4 cannot OC pass 4.9Ghz regardless of how many voltage. (can boot to windows but not stable).

4.5Ghz 1.17V
4.6Ghz 1.23V
4.7Ghz 1.29V
4.8Ghz 1.36V
4.9Ghz ???V

It's bulk finfet. You're lucky that you can get 4.8. Voltages and power consumption show you how crappy it is. CPU speed per core is done for the most part. And you have an excellent chip. There's a lot that can't even make it to 4.5 let alone use your voltages.

You've got one of those better chips out there, mate! Most can't even get to 4.6. No matter the temp! I think most folks would be happy to run it at 4.6GHz/1.23V for everyday use.

From what I hear though, you may try lowering the "cpu cache ratio" and the memory divider, and try using only one DIMM. Then there's the "strap". Also, try using "per core" multipliers in baby steps. Try a single core in 4.9 and all others in 4.8.

But be warned, "temps don't kill - voltage does".

 

[dj-electric]

Even 4.8Ghz is very very respectable, defo in margin of about 10-15% of total CPUs capability.

If his is the better chip, then what is mine with HT 4770k at same volts, uber? ^^


4.4GHz 1.150v
4.5GHz 1.182v
4.6GHz 1.228v
4.7Ghz 1.279v
4.8GHz 1.31v (i didnt test much)

In all cases cache at 4.3GHz 1.143v


Wish I had a 4770k that could do 4.8-5.0GHz at 1.26v, that would be golden

I envy you guys. I haven't been able to get the chassis and coolers yet, so still don't know what cr@p I got in the lottery. Fingers crossed...

is that manual voltage or with offset mode/passive mode?

 

[TheHunter]

That's what I need at fixed voltage to pass all,

Yes now I have it at adaptive for both cache and cpu - same voltages.
But it can go berserk in IBT, Linx, Prime, etc (1.28 >> 1.367v), so I dont run those. Well I know its already stable at those volts mentioned before

and?

 

[l337g0g0]

and?

"When it comes to games, one of the latest and most popular is Battlefield 3 by Electronic Arts. The Core i7-4770K's Hyper-Threading Technology allowed it to perform better than the Core i5-4670K without it."

Hyper threading doesn't effect games, all games use 2 to 4 threads.
How is the I7 outperforming the I5's?

 

[dj-electric]

I thought that by now BF3\4 performance gain of an i7 over an i5 would be something widely known.

And the claim that "all games use 2 to 4 threads" isn't correct at all.

 

[FreedomEclipse]

certain games handle hyper threading differently. some games it works perfectly, for others it creates microstutter issues

Doesnt mean that HT is 100% useless for gaming. Please.... they only used GRID 2 for testing HT in gaming, rest are 3D benchmarks.

While HT may net only a few extra fps at best - thats still something, but like i said it depends on the game itself. every game engine will handle HT differently.

At the end of the day it wont really make much difference for average usage. I could pull out a 2500k and clock it to the moon and it wont feel any 'slower' or 'less responsive' than an extreme series intel chip.

It was 1-3 frame if i remember, and wouldn't that be in a margin of error?
and to that point it's definitely not worth the price differences of both equal MHZ CPU's for 1-3 frames...

Depends, Not everyone uses their PC for just gaming and nothing else which is the bigger picture here but i agree for a gaming machine HT makes very little difference, the Internet has never denied that.

And to the one video about even an I3 is good, I don't know if he remembers that the I5 has Intel turbo boost and the I3 don't which is useful.
So i wouldn't go as far as to say an I3 will suffice...

 

[FreedomEclipse]

Well, the i3 4130 does a lot better than some of AMDs quad & hexa core CPUs even when it comes to multitasking and single threaded tasks, the architecture is just so much more efficient, I have no quams about recommending an i3 (with HT) for gaming and everyday use if the persons on a budget or doesnt need the raw power of a quad. hexa or octa core CPUs.

Dont get me wrong, an i3 might not be a great idea to drive multi-GPu set ups but for a low/mid range set up with only one GPU they can still perform amazing well.

Heres BF4 on an i3 setup:

system specs:

i3 4130 @ 3.4GHz
Gigabyte GTX 660Ti 2GB
8GB Mixed Brand Ram @ 1333MHz CL9
Kingston V300 120GB SSD
Corsair CX 500


IMO ram could be boosted to 1600Mhz or higher but it still reflects a decent budget minded mid range system.

::EDIT::

Its all about perspectives.

l337g0g0 and your point is, seriously?

All I see is you registered today to troll that i7, more precisely Hyper Threading, is apparently useless for what ever reason..

Ps it was in old games, but this isn't 2008-2010 anymore and it will only get more multi threaded from now on, mark my words.

If someone is on a tight budget he/she will definitely go for 4 threaded variant and hope for the best, if "money isn't a limit then 8 threaded cpu is a no brainer now.

Now go troll somewhere else

I can't make an account to add my 2 cent or i'm trolling?
Please.

I was talking about most people that just don't like throwing money to the wind for 2 FPS bonus.
Most of the information i read is current beyond those videos, those are examples.


Multi-threading will be utilized more in games as time goes on, but for now it's not and that's my point.
And you don't have to be on a budget to not waste money on current tech that offers nothing for more money.
