Hello, and thanks for reading this message. I want to know what CPU is more worth it. Here's the case: I got to these CPUs because of their power efficiency. I got shocked when I saw the i3-4340 CPU because it's 3.6GHz with only 54 TDP!!! That is an excelent energy-efficent CPU comparing to the one in the living room that is 2.8GHz (made in 2009) and it's 65 TDP. Apart from that, the built-in GPU Intel® HD Graphics 4600 is much more better than the 2 computers of my house, so i'm sticking with the built-in GPU, no dedicated GPU. Then later I got more shocked when I saw the i3-4330T, 3.0GHz for 35 TDP!!! So it's almost half as the TDP of the computer in the living room (by the way, it's AMD Athlon(tm) II X2 240). The reason they compite each other is because they have the same GPU (some minimal differences in starting MHz, which don't bother me), and one TDP is less than another. They are with the same socket, etc. The only (as far as I know) difference between them is the CPU GHz and TDP (there is in starting MHz in GPU but their max is same with Graphics Max Dynamic Frequency).

The questions are: Does the .6 GHz difference of the i3-4340 is a lot or noticeable better over the i3-4330T? Does the 19 TDP difference in the i3-4330T is noticeable in electric bill? Yes, the time using the computer counts, so I am saying how much I use. To be honest, I haven't got note of the hours a day I use the computer, because it's random. Let me tell you that it could be like 3-6 hours in monday to friday days, depending if I have things in school or not. Sometimes I talk with a friend so it might be different depending on what happens, that's why it's random and I'm not in a fixed schedule. In the weekdays or holidays it's like about 10-13 hours when I don't have anything to do, also it depends if I have school things or what happens, like talk to friend. Average lets say it's 2-4 hours in monday to friday, and 5-13 (yep, undecided lol) hours in weekdays or holidays.

Now, here is another question: Does the .6 GHz is worth it by 19 more TDP? What I usually do is search the web, play flash games, use recording software (not so much lately), play some games (but not latest), so don't need more than dual-core CPU (and I will not because Quad-core and above are not so good for power consumption efficiency, as far as I know), as also this GPU is enough for now.

I want to get energy efficent CPU but I don't know if 19 more TDP will be a lot for .6 GHz difference. Thanks in advance!

Lastly, and optional to the topic: When is the 4330T and 4340 going to Box version (and to amazon)? There is OEM version but I am not experimented with getting other parts so I want box version.
 
Even if you used both cpus 24/7 all year long, it would only come out to a few $$$ by the end of the year.

And for the record, you can almost get a i5 4430(84w) for the price of the 4340. The 4340 is not a good value at all.
 
Thanks for your response, I now wonder if the heat will be a problem. I plan to build and use the fans that come with the CPU or whatever other thing but no extra fans. Now, will the heat be a problem on i3-4330?

Thanks for the recommendation, but I just won't going past 60+ watts.
 
You don't want to use ANY extra fans? Any stock cpu cooler is going to suck, and the cpu cooler is almost always the loudest fan in the case except for video card fans. There may be a noticeable heat difference between the 4330 and the 4330t, but it won't be very much.

What are you building? A micro HTPC?
 
I just want a normal computer. Here are the parts that may be used:
Case - Haven't decided yet, but it will be i3-3***
CPU - Haven't decided either, will decide soon
RAM - I think 4 GB will be enough, this may change
Motherboard - MSI H87M-G43 -LGA1150 Intel H87 Chipset HDMI SATA 6Gb/s USB 3.0 Micro ATX High Performance CF Motherboard, accepting suggestions
Power Supply - Haven't decided yet
GPU - Built-in with the Intel CPUs

As you can see I haven't decided on most of them.

If the case have more extra fans, then yes, but this is my first build and I just know the basics, maybe if I learn somewhere how to put extra fans I could.

Thanks for your response. I won't use a dedicated card.

Okay, can you suggest me by reading above what I want to build?
 
I really recommend at least two case fans. One for intake, and one for exhaust.

That would be a fine motherboard for any Haswell i3, and any Haswell i3 would be a great all around cpu. Even the i3 4130t @ 2.9ghz would be a huge upgrade from what you're using now. I think I would rather spend $10-20 less though and get the regular 4130 @ 3.4ghz or spend $10 more and get the regular 4330. That's up to your budget. The 4330 is 100mhz faster, has better graphics, and more l3 cache over the 4130.

4GB of RAM is enough for most people. It could easily be upgraded later.
 


I just want a good case which support what you said, the 2 fans, one for intake and one for exhaust. More fans is of course accepted. No LED light or anything, just what I need. Which case do you recommend me? Also, I want power-efficient (no need extreme power-efficient, just what I want without energy wasted) power supply and mobo and kind of stuff.

 
Hi all!

If you don't mind I'd like to ask you some questions.

I'm building a new PC, and I'm thinking about buying a i3-4330T mostly because its TDP. This is going to be a 24x7 machine, desktop use, no games at all, some movies. Almost an HTPC. I really don't care about the processing power because my current 7-year-old E6320 @1.8Ghz is still enough for me. What's important to me is a low power consumption at idle state and a noiseless device, possibly with Intel's boxed heat sink and fan.

So... my questions, related to this topic:

At (mostly) idle state, there is a different power consumption between i3-4330T and i3-4340?
Do you think I can get almost silent pc with i3-4340 and it's standard fan? If not, I can get it silent underclocking to 3.0Ghz like the i3-4330T?

Synthetizing question: given my requirements, and apart the fact i3-4330T isn't sold boxed with fan (... right?) what you suggest I should buy?

thank you in advance for your time.

Ciao!

 


You will see absolutely 0 difference on your power bill going with such a low wattage CPU. Just a simple change in the weather causing to you to use heat or AC more would have a larger impact. I went from a fire breathing monster of an overclocked Kentsfield Xeon X3210 to a much cooler Core 2 duo E8190 to save on power bill. It didn't affect my power bill at all. By the way, an ivy based Xeon 1245 v2 is only 77 watts. It is an i7 that still has IGP and quick sync. 😉
 
Thank you for you answer.

It isn't only matter of power bill, I know it makes very little difference by the end of the year. I'm wondering if a 54W TDP processor lets me to completely stop the Intel's boxed fan while idle, so making no noise. My current E6320 lets me do to so, but it is cooled by non-Intel big heat sink. As far as I can tell, Intel standard cooling system aren't so good and a little bit noisy. I'm not so sure, but I think the 35W i3-4330T could stay fan-less while idle, so I'm wondering if I can do the same thing with a i3-4340.

ok... maybe I'm worring too much about this thing 🙂
 
thank you, I'll keep in mind.

I'm thinking about this thing, that could answer all my questions:
an i3-4340 downclocked to 3.0GHz can be equivalent to an i3-4330T, talking about cooling needs and overall performances?
 


You cannot downclock an i3. They are locked chips. I really think you are overthinking this.
 
What exactly are you trying to accomplish? There will be little to no noticeable difference in power draw from a regular 4330 to the 4330t. You can undervolt and/or underclock just about any cpu. You can lower the ratio on most locked cpus like the i3 if you really want.

I think you are overthinking things as well.
 
All 2nd gen and up i3's are fully locked. Messing with the base clock, (similar to FSB) will cause stability issues. Honestly, you are putting in a lot of thought into something that will give you 0 benefit. I still think the 1245 v3 is the best combo of performance per watt, though. I used to passively cool my E8190 @ 3.8ghz too. :lol: Did it with an old Thermaltake tower cooler I had bought cheap years ago.
