The i3 is significantly faster per-core (don't compare clock speeds here, meaning the gigahertz [ghz] number, different platforms have varying IPC - instructions per clock), though the AMD chips can catch up with skill, effort, and higher power use through overclocking.. The i3 also isn't a true dual-core. It has hyperthreading, which helps out a surprising amount in games that can use 4 threads. Overall, I'm a gamer, and the i3 has equivalent or superior performance to an overclocked "quad-core" if by "quad-core" you mean an AMD Phenom II x4 or fx-41X0, especially in games that are CPU-bound like StarCraft II and Skyrim, and which I also play. And because of the way games are programmed, per-core speed is much more important than total CPU potential. For instance, SC2 can only use two cores, so the fastest two cores possible is what you want. Skyrim can use basically two cores, but really only the first is heavily taxed, so again, the highest per-core speed is what you want. Other 'multi-threaded' games show a similar bias - because of the way games are programmed usually only a few cores are heavily taxed - and these are the ones that limit your performance.

Don't get me wrong, AMD would be great if you were both gaming and doing some other multi-threaded task. Although in that case I'd recommend an fx-6xxx. And a stronger PSU. Don't use the cheap PSU I recommended if you plan on overclocking an AMD chip. Though the fx4100 would be ok on it, I guess.

But the kicker for a gaming situation is simple: the i3 is cheaper, and allows for a better video card. Combined with not sacrificing performance, and I don't care if it's single-core, I like better performance for the same price or cheaper.

P.S. Copied from another post:

Note those games above are CPU-limited games. Most games couldn't care less which processor you put in your computer.

So would an i3 or Zambezi 3.6Ghz Quad Core be better?

EDIT: Lets make it a 3-way. Let's throw the Phenom with those 2 up there.

Definitely i3

You're falling for AMD's MOAAARRR CORES is better scheme

is this rig only going to be used for gamming?

See the charts I posted above? The fx-4100 with the green & blue bars is a stock fx-4100, also known as a "Zambezi 3.6Ghz Quad Core". Phenoms are also on the list. The blue & green bars are for stock, the red bars are for overclocked.

Oh sorry, I thought I already acknowledged your 2nd post. I appreciate the in-depth explanation. Only if the Sandy Bridges weren't so expensive.

The fx series is a very capable performer in the correct scenario. ie, 1920x1080@60mhz and single gpu config. if you want fx buy fx. Just read and listen to the varying opinions on ocn first and make an informed choice.

if you dont mind used your 600 budget can go alot further here on OCN market, at the end of the day AMD performes at the same level as intel and beats it at diffrent levels even the charts that where posted show this the 965 outperformes the I3 the chart shows this and gives you the option of over clocking the I3 you can't OC it its locked dose AMD cost a little more to overclock yes but when you want to out performe it costs more no mater if you go Intel or AMD

Yes, actually, even though I routinely tell people they don't when I talk about the i7 tongue.gif.

Basically, almost no games use more than 4 cores, so the hyperthreading of an i7 is useless for games. However, the hyperthreading on the i3 (2 cores, 4 threads) does occasionally help for quad-threaded games. Not much though. The i3 line's larger benefit over the pentium line is actually better L3 cache. But now we're getting off-topic.

Hyperthreading is somewhat relevant here (performance of an i3 vs an AMD true-quad-core) for one reason: the hyperthreading helps the i3 in the very few occasions the AMD processors have a real advantage over the true Intel dual-cores like the pentium g850: quad-threaded games that care at least a little bit about CPU. In those few occasions, the i3's hyperthreading gives it an advantage over the pentium g850 and pulls its performance to even with overclocked AMD quad-cores (and keeps its lead over non-overclocked AMD processors like the OP was considering).

So the answer to "do games use hyperthreading" is actually 'a little'. Although in some games that can theoretically use more than 4 cores (BF3), hyperthreading has actually HURT performance on some occasions. (Why? The game thinks it can use lots of cores efficiently. In practice, it is more reliant on a few fast cores, as I outlined in an above post. By engaging hyperthreading on the one or two cores being heavily used, hyperthreading actually creates more problems for the resource bottleneck - the few cores in heavy use - in an attempt to get more threads in play).

This, too, virtually never comes into play for the i3 (as indeed, it virtually never does with the i7, just really that one example I can think of).

None of which really needs to be known for a good purchase decision. It's not as important as price & overall performance for the stated task. biggrin.gif
