i7 4770k vs i7 4790k

[Nacherdocia]

Please I need to choose between these two processors. I'm not quite known of this devil's canyon one, so if someone could help me with this it'd be great.

Ps: I've started building a new system and it's my first time.

Also please if you could help with the decision of an asus maximus vii formula or a gigabyte ga z97x gaming 5.

[Totallycasual]

Go the 4790k

[babadoctor]

For what? FOR WHAT????? what is your system for??? gaming??? More info please

[NeverNotExhausted]

They are the same die, the 4790k has a clock speed bump and better thermal paste between the die and the IHS

[adamsjus1]

The 4790k has better temps so higher overclocks soo.....

[Luckylock]

4790k basically the same as a 4770k, except:

 

- Lower temperatures

- Higher stock frequency

 

Go with the 4790k.

[Kermit]

^^^ yeah 4790k - better specs

 

By the way, welcome to the forums @Nacherdocia !

[HEU7Hwhu7]

4790K has a better TIM, So it OC's better. Not much different. If you can get a 4790k,get that.

[ComradeHX]

Is there a significant price difference?

If not, go for 4790k.

[Frankie]

What the guys said (4790k if there's not a significant price difference). As for the MOBO if you are first time builder you probably doesn't need all of the overclocking bells and whistles that the MAXIMUS VII FORMULA has. I would go for the GIGABYTE GA-Z97X-Gaming 5 decent MOBO decent price. Probably still fits your red/black theme if there's one. Welcome to the forum dude/dudette

 

Edit: Make sure you follow your post @Nacherdocia button at the top right.

doesnt matter that much 4790k will overclock a bit better tho

[Sintezza]

4790k also has more caps and what not added to the chip, for more stable and better power, for more stable overclocks.

More transistors were not added to the chip. The architecture and construction remains identical to the 4770k's. The only physical difference is the TIM between the die and IHS, they are also binned slightly higher.

Sintezza is right, they added two extra capacitors on the chip to allow for more stable power delivery:

Full review for devils canyon, interesting read.

 

SUMMARY:

Overclocking

The overall temperatures when the CPU is overclocked with added voltage definitely is better opposed to the 4770K. I think that being in the 70 Degrees C at 1.4. Volts on a Corsair H110 LCS cooling kit really is respectable. But weirdly enough that doesn't show in the actual overclock results. In fact we can actually go 100 MHz higher with the 4770K (albeit with worse temps). No, it seems that after 4700 MHz on a proper cooler this processor will meet its threshold, and honestly I expected this CPU to pass 5 GHz with our cooling. Perhaps over time with a few BIOS updates this will change. But realistically I think your maximum OC target will be roughly 4600 ~ 4700 MHz if you search 100% stability. Our 4800 MHz tweak was stable enough, but not stable enough for hours of 100% CPU load. And at that stage we already needed 1.4 Volts. I am still running some overclock tests and right now I am at 1.45 Volts / 4800 MHz. This for now is 100% stable however temps are growing to roughly 85 Degrees C on the package sensor. Devils Canyon needs a lot of voltage to be overclocked, and as such requries hefty cooling to accomplish high overclocks.

Sintezza is right, they added two extra capacitors on the chip to allow for more stable power delivery:

Transistors are not capacitors, we were both wrong :blush:

Adding transistors would fundamentally change the CPU architecture, while capacitors would only be used to change power delivery characteristics.

wow lol, yeah i ment caps.

correct.

Go with the 4790k.

Can't add any other reason.

Go with the 4790k

in some part of the world the i7-4770K is noticeably cheaper and Z87 boards are also cheaper...so it depends...

I had to suggest a build for a dude in india last week and the links of the shops where he planned to order from man, the Z87/4770K kit was like 20% cheaper than 4790K/Z97

Nice, I also thought about getting a Z87 for my 4790k, but they were no were to be found on my country. So I ended buying the Z97 even though I'm not planning on upgrading to Broadwell

That's for the best anyway. As far as I know, some Z87 motherboards may still require a BIOS update to add i7-4790K compatibility. Z97 works out of the box.

Do you know that the Z87 would probably need a BIOS update for the 4790k to work ? That is the benefit of Z97 for Haswell Refresh, drop it in and go.

 

@typographie Damn you ninja

 

For anyone wondering I had this window opened and didn't refresh, my bad.

[Masamune]

Go with the 4790K!  Amazing CPU

[CatzRuleZWorld]

The 4790k is probably cheaper even... Only get the 4770k if it's like $50 less than the 4790k

[Ynkeeblood9]

4790k especially because I believe there close in price right now.
