HI guys,

I am getting new system and hardly into gaming. I planning a reasonable fast system with 32GB RAM, PCIe SSD as boot etc...

Most of the time, I do not need much processing power.

I aware that Intel show different power for 3 type of i7 processor. And the 6700k that rated 91watt seems easily exceed 100+ watt in many review.

I am very concern on temperature... I know 6700T is what I needed. But I did not see it in any store.

So my questions is... should I buy;

6700 - Just run as it is...
6700K - underclock and undervoltage it... wonder can get similar power consumption as 6700T?

if dont do overclocking and just for working.just take the 6700. 6700k and 6700T doesnt have same power consumptions.because the 6700k its build for overclocking and need power to reach higher clock. 6700T is underclock and locked multiplier. better go for 6700.

If budget is not a limit, I would suggest you to go with 6700K, it can be undervolted like 6700 or 6700T.
It also allows you to overclock to an average of 4.4GHZ on all cores = close to a 3820K 6 core performance in multi-threading when you really need the speed.
If you do not need the hyper threading performance, then might go for 6600K.

6700 is indeed whats in my mind.

I think budget is of course no issue for anything that can afford 6700.

Current C-Zone price;
CORE I7 6700 (4C/8T) RM1272
CORE I7 6700K (4C/8T) RM1431

The price is just less than RM200 differences. The concern is on the power consumption. Many website revealed that 6700k actually consume more than 100 watt.

I actually had the idea to underclock and undervoltage. But I wonder how power effecieint I can get down to. Similar to 6700T performance and power efficient? I failed to find any web review doing that. If you found one, hope can share... notworthy.gif

You don't need to be worry about power consumption with either CPU.
The reason why 6700K uses more power is because out-of-the-box, it's based clock speed is set at higher speed.
6700 (3.4GHZ base / 4GHz Turbo)
6700K (4 GHz base / 4.2 GHz Turbo)
Use the motherboard UEFI/Bios to tune the 6700K to 3.4GHz base and 4GHz turbo - or you can even set it till 2.1 GHz = did that on my 3770K , very low power consumption).
Since you are able to afford a PCI-e SSD (Samsung 256/512GB), RM200 difference is not that much - it gives you the flexibility to get higher speed when you really need it.

I have the 6700k for months at stock speed and haven't start overclocking it yet, running it on the famous Hyper 212x cooler with no heat issue at all (temperature at 45~5x c degree in non aircond room).

I went with the I7 6700K because I don't upgrade often and I am reserving that extra OC power for future, if I ever wanted to OC for some reason.

However, if you decided to go with 6700k, you will also need to pair it with the more expensive z170 motherboards so it all comes back to your budget.

But if you're absolutely have no interests in OC then go with the 6700, then again you also do not need a high-end cooler for it and something like my 212x should do, replying to your other thread about heat sinks. smile.gif

On side note, since you're not into gaming, mind if I ask what are you using this "reasonable fast system" for?

According to Intel - the TDP (note that TDP is not an accurate power consumption - it can be higher, or lower, depending on the load condition) is 65W.

Power consumption is irrelevant since most reviews often use very unrealistic loads (aka worst case scenario) which are generally not reflected in real world use - note Anandtech uses OCCT for stress testing.

Even the power consumption of the whole system (i.e. a GTX970 with a 6700K) at Prime95 (again it's not a real world test since Prime95 is a highly synthetic test intended to stress the CPU to the max) is just 121W.

Don't bother with underclocking and undervolting - you'll be losing performance and stability (lowering Vcore can render your system unstable) icon_idea.gif
Even if you managed to do so - the trade offs is just not worth it. The CPU itself already has a lot of power saving measures. icon_idea.gif

6700T is not sold in retail markets - they are intended for OEMs only. icon_idea.gif

wait, you mentioned you dont need processing power, yet you opting for i7 unlocked hmm.gif

why would you need an i7 or a K processor in the first place if you dont need processing power?

just chuck in PCIe SSD and lots of RAM, even with i5 i3 etc you get an exceptionally fast system

From his previous PCIe SSD debacle thread, he wanted to run 'simulations for 1 hour to a week and to see result faster' is what he wanted. Don't know what kind of 'simulation' he mentioned.

Good question on why i7. If you looks at retail prices, there are not much differences... around RM200 if remember. I think with Intel pricing, it more like want people to buy i3 or i7 only...

And about RAM... Thanks to today that RAM is really cheap... laugh.gif icon_rolleyes.gif
