Which CPU is better? the 4 core sandy or the 2 core Ivy?

And what if the performance needy software isn't threaded (or well threaded) ? Still lots of software like this exists (most I would dare to say).

Sorry you just jumped to conclusion, and now you are feeling butthurt and throw insults around like:

Feel free to defend the opinion of yours, nobody is depriving you of the right to do so, but please for your own good and for the sake of decent discusion do it in civilized way like others.
 
So? That kind of software is both rare and it wouldn't make much of a difference considering the very close performance per core between the two chips.

Did you just say butthurt? Oh yeah, I forgot I was the insulting one.

Civilized is the last adjective I'd decorate the other posters with. Words like badass and butthurt can not be found in my posts, but the blissful abundance of such words in your posts make me ponder over certain things.
 
I quit posting to computer forums because of the constant back and forth bickering between all the Intel and AMD fanboys.

Intel now has the enthusiast market so now we are fighting between 4cSB an 2cIB? This is just silly. I think at the heart of the matter we all agree that it is going to come down to information we don't yet have from the OP.

Maybe Paulcheung can fill us in on exactly which platforms he is considering and exactly what the intended use is going to be?

If graphics is not an issue a 2cSB might be best for the money???
 
Just to add: lots of people are using i3 (2c+HT) and they are good for everything from productivity to gaming, even BF3 which can be seriously CPU bottlenecked is solid on it.
Of course for lots and lots of video encoding 3770k is better.. or 3930k or xeon.. you have many options to choose from and you should choose based on your needs.
Hell even SB pentium packs serious horsepower and that's just 2c. For many people even that is overkill. 🙂

We just cant say 4c>2c+HT and be done with it. Depends on price, power consumption, clockspeed, usage model and maybe something else...
We need these information, OR we can say which is better in what, and let OP decide what he needs 🙂

^This
I was lurker for many years, because I didn't want to get caught in these stupid fights...
I started to post because I thought I had something relevant to add to the discussion, be able to help other people and avoid this kinda situation. For a while it was going ok...but I guess I thought too highly of myself ... :\

I can't help to notice a lot of the new middle class laptops even some so call highend laptops are coming with CPUs have 2 cores with HT. are these 2 core i5 or i7 are better than those 4 core i5 which produce a year or so ago? or the manufactures just believe we don't need the 4 core's power until we want highend gaming laptop?

Any comparision bench mark on these 2 core i5, i7 compare to the last generation 4 core i5?

I am just curious.

Since you mention laptops I assume you are referring to mobile M labeled processors – so I will address this.

All of the i5 series mobile processors are 2C/4T (dual core + HT) HT = hyperthreading making 4T - 4 threads. Even the lower end i7 SB (Sandy Bridge) mobile processors are dual core 2C/4T. Only the models with QM in the model number like the i7-2630QM are quad core mobile processors. The same thing applies to the new Ivy Bridge mobile processors.

You can check out and compares some mobile processors benches with … PassMark.

Score …

i5-2540M … 3,785
i7-740QM … 3,626

The newer SB based dual core (2C/4T) i5-2540M is actually faster than the quad core i7-740QM in this multithreaded benchmark. So the new faster 2 core mobile processors can outrun some of the older i7 quad cores, but those old i7’s are 2 years older or more. With the newer generation mobile processors expect the quad cores to be (generally) faster than dual cores.
 
Sorry guys, don't mean to start a war here. sorry that I didn't give enough information.

As I read all the replies that come to another question, If I want a quad core Sandy with dedicated card, which card (atleast) will beat the Ivy's HD4000? I was told the hd4000 are better than some dedicated card.

I have a Dell inspiron 1420 which come with dual core t5500 and I upgrade it to a t8300 and 4gb ram. it perform better than before. but it has trouble to open 2 video player the same time, example I open VLC to play a video and windows media player to play another video the same time with an external monitor. one of the video will lag or freeze sometime. The graphic chip in the Dell is Nvidia 8400?s.

So, to prevent this happen what should I choose if money is not problem and battery is no concern? the quadcore sandy with what video card? or Ivy will provide plenty power for the purpose? and if I want to convert video from one format to another say mkv hd to regular avi files. sandy won't give too much advantage?

Thank you guys.

Yes. Problem is that's comparing to desktop cards.

Well, that leads to a difficult question: What is the bottleneck in your system?

- It could be the CPU, although that depends on the video resolution. If you play both videos with two VLCs, what does your CPU usage look like? (You should disable hardware acceleration.)
- It could be your hard drive. If you play the videos for a couple of minutes, then rewind them and play them again, are they stutter-free for those couple of minutes?
- It could be your GPU. In that case the video should work with two VLCs and no hardware acceleration, unless your CPU was at 100% above.

If I had to guess now, I would say that an SSD would be most likely to make your current laptop work for this purpose.

Well, that's a whole other issue. You're converting size as well as container format? (What's a "regular" avi file?) If they're both H.264, but you're reencoding, the true quad-core has a big advantage.
 
I converting larger files say 3 to 10gb to 1.2gb or less so it will play on less powerful computer in less quality.

I do shut down the hardware acceleration because the gpu is not a good one.

Thanks.

Temp ≠ Heat Output

AMD places their diode in a different location than Intel, they have lower temps, but a lower max operation temps. Their cpu isn't any cooler running however.
 
Intels mobile parts for sandy bridge were also 2 core, 4 thread parts, it's only the desktop parts that feature more cores, iirc. Are you mainly interested in laptop chips?
 
There are 4c8t mobile chips, just no 4c/4t mobile parts.

The naming is kind of confusing on laptops, for instance the i5's are all dual core, the i7s can be dual core and quad core.

If you are converting video regularly, and you are using program that is well threaded, I would recomend getting as much threads as you can get with your budget and other constrains.

By the way I'm typing this in 2C+HT and HD3000 sandy laptop and I have no problem playing 4 videos in VLC at once (maybe even more haven't tried).

Dedicated card only makes sense if you want to play games, or HW accelerate other stuff like Video conversion (but you have to be careful about support, different cards works with different software), but then you wouldn't need CPU with many threads.
 
If I may venture: you may be more satisfied with 2C+HT and an SSD than 4C+HT and a regular spinning hard drive. It really does all depend on your use case, but for the vast majority of people what holds them back is disk I/O, not processing power. If you're doing ordinary things and want very good responsiveness, any Sandy or Ivy hyperthreaded dual core and an SSD is what you're after.

In very, VERY brief:
- Dualcore + SSD for everyday things, add discrete GPU if you want to game, or consider an AMD A10 if it's not very very heavy gaming.
- Quadcore for lots of computation, like parallel processing (i.e., Gentoo compiles or large Matlab datasets). Quad + dGPU if you are a hardcore gamer.
 
to answer the question, ivy appears to be like 10% faster clock for clock and it has 10% faster clocks in general.

So that's like 12.1% faster, if you're looking at sandy i5 vs ivy i5.

Now, i3 vs i5 it appears to me that the i5 is more than 12.1% faster. Maybe like 40% faster. So a sandy i5 would be faster than an ivy i3.

I wish Intel would quit the name confusion with it's mobile CPU's. And to complicate things I'll mention something that I haven't seen anyone else talk about. Playing around with configurations on the manufacturer's web sites I'm seeing it's not just core count and thread count that change but clock speed too.

Example: I'm looking at an HP laptop where the options go from

3rd generation Intel(R) Core(TM) i5-3320M (2.4 GHz, 3MB L3 Cache)

to

3rd generation Intel(R) Core(TM) i7-3612QM (2.1 GHz, 6MB L3 Cache)

So with this particular laptop, when you go from the i5 up to the i7 "QM" quad core, you also get a decrease in clock speed. Lower base clock and also lower turbo clock (3.3 Ghz for the i5 and 3.1 for the i7). So for single threaded performance you may actually be WORSE off with the quad core. Of course faster clocked QM's are available but you already have to pay $150 more to get the 3612QM over the i5 and clocking it faster will make the difference in battery life even worse.

So when you factor in the additional cost of the QM and the increased power usage, I think you really have to think hard about weather or not you have any tasks that will really benefit.

lol. I had to laugh at that one.
 
So, now they have i5 2core 4thread and i7 2core 4thread, what are the different on these chips? away from their name and numbers?
Thank you.
 
But overall, I'd probably prefer an ivy bridge i3 over a sandy bridge i5.

b/c performance of the i3 would still be quite good while the thermal profile and power consumption would be much smaller. It's something like 55 watts, which is down from 65 watts of the sandy i3 and almost half that of the sandy i5 95 watts.
