performancewise they are very close in sc2. sc2 doesnt benefit from more than 2 cores, so u have 2 cores at 2.4 ghz with the i7 (turboboost feature!) vs 2 cores at 2.53 ghz with the p8700, but the i7 has more cache. they should pretty much give the same results in sc2. and plz dont quote some silly desktop benchmarks as they have no relevance for laptop hardware. 
the i7 is the more modern, future-proof and effective cpu though, so if the price isnt an issue, id go for the i7. in particular as the chance is high that blizz will improve the sc2 support for more than 2 cores in the future, and if this happens the i7 will destroy the p8700.

I have never seen some many people spewing ignorance all over a thread.
There is absolutely no way, that a core2duo is faster than a core i processor. No way.
The cores is not the only thing to take into account. The core i3/5/7 processors have a HIGHER bandwidth, are of a newer architecture and therefore are faster.
Comparing clock speeds is not an intelligent way of making a comparison.
a 2.0ghz corei7 will rape a 3.0ghz core2duo hands down in every game and task.
Remember when core2duo came out?
people with pentium 4 and pentium D processors clocked at 3.0ghz couldnt believe a 1.8ghz processor was a lot faster.
Its the same thing all over again.
Op, buy corei7 and future proof your pc.

G72GX-RBBX05 is clearly older, it will run sc2 better becuase it sports a lower resolution 1600x900 vs G73JH-RBBX05 1920x1080, that being said the G73JH-RBBX05 is a much better laptop overall
But the G72GX runs a 260m which is like a 8800GT the G73JH runs a 5870m which is like a 5770, which will run about the same in SC2 just due to the game bias that likes nvidia drivers quite a bit more (ati isn't showing the optimized love)
I'd go with the G73JH frankly larger resolution on screen better gpu and cpu it's a better laptop, if you need to run sc2 just have turbo mode enabled, which should auto change up the cpu and self correct.

I would say amused. i7 will probably be rendered obsolete in weeks.

oops
my bad~

I'm playing SC2 on a laptop with the i7-720QM and it runs perfectly, so if you are concerned the speed of the cores you shouldn't be.
Now if the game runs better with the other cpu, i guess it'll depend on the build but with the i7-720QM the CPU atleast wont give any problems.
|
Seeing as ill be playing starcraft 2 ALOT will it be safe to have the turbo mode on for long periods of time?
|
Turbo boost is a feature enabled by default. Haven't you seen Intel's commercials where they're like "omg it self-optimizes?" The processor just automatically adjusts its clock speeds to a certain point until it reaches some thermal limits, in which case it'll automatically dial back slightly as needed.
|
the core speed is really not everything. think of a car with 1000HP, its still gotta put that power on the road.
the i7 is def not the better choice.
P.S. If when you read HP you thought "hitpoints", yes, I'm afraid you're a nerd.
P.P.S. I did, lol.

Be sad, he's talking about laptops not desktop where i7 is definitely not future proof. For a laptop it is.

There's not a single feature other than 25wtpd that is better on that dual core.

..lol There are very few games that use more than 2-cores. So if we're talking strictly for gaming, you're comparing the p8700 to the two cores on the i7. In that case, the c2d is at least comparable, if not better than the i7 if the i7 is at 1.6ghz and the c2d at 2.53ghz. Not to mention I bet the c2d will be a LOT cheaper.

Did you see any of the posts that mentioned that when using 2 cores, the i7-720QM can go up to 2.4 GHz, or that the i7 has 4X256 KB L2 + 6 MB L3 cache compared to 3 MB L2 cache on the P8700, or that the i7 has a more advanced architecture that's faster clock-for-clock?
Granted, the difference isn't going to be huge in games that aren't threaded well, but it's crazy to think the P8700 could be better in performance.

You probably have an old ass pc and are trying to feel self-assured you don't own dated crap.

Yeah, because a core2duo is more future proof than core i7. Your comment says that you don't know much about hardware, and have absolutely no idea what intel's roadmap is.
I'm pretty sure corei7 will remain a competitive processor at least a couple of years from now. Core2duo is already obsolote.

There is a reason why core2duo is cheaper..
I'm getting the impression you guys don't know what a benchmark is. I challenge you guys to go to a technology forum and post that core2duo is faster than corei7. It doesn't even matter if it is a multithreaded app or a single threaded app, corei7 is faster, thats the way things are. The wolfdale architecture (core2duo) is dated, there is absolutely no way op will be better off buying dated hardware.
"few games use quadcore processors" is an opinion either from 2 years ago, or from someone who only knows starcraft.
Here is a small list of relatively new (2008-2010) mainstream games that make use of 4 processors
Dragon age origins and its sequels (up to 60% faster on a quad core) Alien vs Predator Grand theft auto 4 (unplayable on a dual core) Battlefield bad company 2 Prototype Metro 2033 Crysis Warhead The last remnant Supreme Commander and its sequels Spore Lost planet and its sequels World in conflict and its sequels Alan Wake
and the list goes on and on...
Again, there is absolutely no way OP will be better off buying a dated dual core than a new quad core...
Even if Sc2 was poorly optimized the corei7 would have the advantage.
Please understand that you cannot use clock speeds as a reference when comparing diferent architectures...
Here is a benchmark chart comparing a core2duo processor e8400 (3.0ghz) and the corei7 920 (2.66ghz), core2duo loses everytime eventhough it has a higher clockspeed...
Benchmarks
Here is another chart comparing the weaker corei5 650 vs core2duo e8400, both dual core processors, core2duo loses again...
benchmarks 2
Ceteris paribus the mobile versions of these processors should behave similarly.
Op will be better off buying the corei7.
|
Processor isn't that big of a deal for SC2. i7 would be better, however I'm at 2.4 ghz quad core and I'm running CPU wise fine. As long as you have 3 gb of ram, and a good graphics card (and considering your CPU isnt 2004 1.6 duo core style), you should be fine. I'm 3 gb ram, 2.4 Quad, GeForce 8600 and I'm enjoying the graphcis quite fine. Your i7 probably can't run at max settings though.

You sure i cant run it at max settings? even though it has a i7, 6gb ram, and the best part ATI Mobility Radeon HD 5870 (which is apparently one of the top graphics card on the laptop?)
