Can someone explain to me why i7 loses to Phenom II 965?

Not looking for an argument/fight etc.

I been browsing the net and I would pass by benchmarks where the Phenom II 965 would best the i7 920 in gaming?

I understand that in applications etc i7 920 is much better but why is it in gaming it lags behind?

from the benches I have seen.

if im wrong if someone has links to accurate more up to date benches that would be nice.

Thanks In Advance.

Well were they running the same clocks? or stock clocks? Cause at stock clocks i think the 965 might pull ahead, but if OC'd to the same speeds(4.0 for example) the 920 would win probably.
Simply because in games not optimized for multiple-core processors, the AMD chip has a higher clock speed and is therefore faster...stock. What 99% of those reviews don't take into account is that the 920 can reach much higher overclocks than the 965, in which case the 920 would destroy it. If they were to compare the chips at the exact same clock speeds the 920 would win hands down.
Ah ok.

but during game during those benches itsnt turbo boost kicked in on the 920?

I dont think those benches represent it being locked at 2.67?
Yes, but still, 2.8GHz vs 3.4GHz?

Turbo could also be off, resulting in .73Ghz difference.
First of all AMD as alway build there cpus for gaming and Intel is alway to data processing like video editing, office use, and etc.

Yes, but turbo is a joke. Every 920 D0 I've come across can hit 4ghz with ease.

Clock for clock. Meaning same speed. Amd PhenomII 955 or 965 will beat i7 920 in about 80% of games out there. And also depending on what video card you using too.
AMD 955 will game just as good at a Intel i7 920. just AMD is $160 i7 is $280. haha nuff said AMD ftw.

I've seen that as well, although I have one question.

I am going for biggest bang for my buck, but when you go with the AMD 955 you lose out on the triple channel memory.

I was first looking at building a system around the i7 920 and then get 3x2gb triple channel memory.

If I get a AMD 955 I would have to get dual channel at either 2x4gb or 4x2gb or what ever memory set up would be best, cause I really don't know.

I've had a hard time trying to find out the performance difference between those three options.

And here I was hopeful that the fanboys would stay away til page 2. Sigh.

No, clock for clock the 920 destroys the PHII. The only measure in which the PHII beats the 920 is at stock clocks, as has been mentioned here already.

If you brought the 920 up to the PHII stock speeds, the 920 would run circles around it.

But in so far as gaming alone? Until games become truly able to take advantage of all four cores - you'll only see a mild (<10%) difference in overall FPS if the video card is the same when both CPUs are at stock.

That being said, if you use multiple video cards, you will begin to see where the i7 starts to shine. Multiple GPUs are handled better on the i7 (not to say that it is handled poorly on the PHII - just better on the i7) especially when you get into Tri or Quad SLI/CF.

Tri Channel memory's advantages are really only seen in intensive video editing. Bang for your buck AMD has always had the crown there. A good set of fast dual channel memory is plenty good for gaming and other general use.

Hmmm, Thanks for the info, I'm just trying to build a system that will last me for a long time and be the best bang for my buck so I was trying to compare the performance of a i7 920 and the AMD 955.

The point about more intensive CPU games in the future is also something I should take into consideration as well... Blah, I can be too indecisive at times.

You must work for AMD.

As it stands, and I don't care what kind of a fanboy you are, buying an i7 system just for gaming is a waste of money.
I'll try to keep this as non-biased as possible. Look at my sig rig. If you notice, up at the top is a name that says "i7 ordered". This is due to the fact that in games that I like to play, Dragon Age, Farcry 2, Mass Effect, The Last Remnant, (and probably other games most people find terrible), the OC'd i7 gets better performance. This is not to mention, with the i7 I shave some time off large macros running in Office 2007 (which is a good reason to have a decent processor), and is mainly why I went i7. Will you see real performance differences in the two processors? No, at least at stock speeds. If gaming is your one and only priority, go with the cheaper 955/965. AMD is great about not changing the socket every year as well.

i7 is gaming + mutlimedia/large processing/etc. That's where the price difference comes into play. That's not to say your AMD can't run multimedia and editing software well, it just means the i7 can do it faster. You pay a premium for that.

Spot on. Also, I assume most of you use v-sync. If you have a 60hz monitor and your AMD gets you 65fps in your favorite title and the i7 gets you 70fps. If you're using v-sync, it doesn't matter. I use it. (Removed exaggeration)

I know that's the most obvious statement on OC, but seriously.

AMD and Intel prices are getting closer and closer together. AMD is still cheaper, but like previously said when overclocked the 920 can own.

i7 920 $200
AMD 955 $160

Wow a big $40 dollar difference.

DDR2 and DDR3 are coming really close together in price so you might as well get the better technology.

Only thing you have to worry about now is getting a good motherboard.

I'm assuming those numbers are just for example because there is no way in hell an i7 is that much better than a PHII in gaming. More like 2957FPS and 3000FPS.

What are you talking about?

There is a $120 difference

+1 The price difference is so small I don't understand why you would even consider a PhII unless you were strapped for cash.

Microcenter has them for $200, plus you can get a good used chip for around $200 if you don't have an MC near you. Why are you paying retail anyway?
