Photoshop also depends heavily on the GPU

Hi guys ,
Intel dc T4500 and AMD P320 which will better ?
which cooler ?? gonna use for play game or non off 24/7 .

P320 cooler, but T4500 better performance...

oh .. thx

I would rather go for cooler as my PC only rest for 30-40mins every other day.

http://www.cpubenchmark.net/cpu_list.php

better check here

may i ask why dual core processors are better than quad core processors when it comes to games?
something about the clock speed right? what's that?
oh yea, i5 is dual core 4 threads and i7 is quad core 8 threads right?
what are threads? biggrin.gif

i have breakdown ur question into 2 parts.
1. most of the games only utilise 2 cores. the problems with i7 in gaming are low clockspeed and HT(i will explain this in ur 2nd question)..
2. i shall use my explaination from another thread to answer u.

games nowadays are either dual core optimized (pure PC titles, think RTS games like Starcraft 2) or tri core optimized (console ported titles)... so quad core is basically a waste since u only use 2 or 3 of the cores when playing games... and since dual core CPU runs at a higher clock speed compared to quad core CPU for the same power consumption, generally dual core gives better performance over quad core CPU...

only in rare cases where a quad core performs better than dual core in games, eg GTA4, as the game was poorly ported for PC and thus quad core is preferred...

so for gaming, the sweet spot is actually tri core (Phenom II x3), followed by high clocked dual cores (Core i7-600M, Core i5-500M, Phenom II x2), followed by quad core (Core 2 Quad, Phenom II x4)...

Core i7 quad core is not a really good CPU for gaming, biggest reason is the low clock speed... at only 1.6GHz, it's not really that good for gaming needs... the CPU is designed more for tasks like Photoshop, video rendering, etc...

detailed analysis, thanks.
but why lower clock speed on quad core compared to dual core?

what about i3-330UM,1.2GHz vs i5-520UM,1.06GHz? Turbo Boost is really useless while gaming?

more core = more heat = more power consumed

higher clock = more heat = more power consumed

i believe u re referring to AW m11x...

personally i would pick 330UM...640UM is bloody expensive, but is still at the same clock speed as 330UM, while 520UM has lower clock speed than 330UM...

Turbo Boost is pretty pointless nowadays since most programs are multi-core optimized...

Yeah, was referring to AW m11x...so a higher clock i3 performs equally the same as a lower clock i5 with turbo boost when it comes to gaming. So for a person who only uses the M11x for surfing, word processing and casual gaming, i3-330UM is the better choice, right? thanks for the explanation

refer back to my posts, games nowadays are dual/tri core optimized...

Turbo Boost works by shutting down 1 of the 2 cores in the CPU and overclock the other one so that single threaded programs can be processed faster...

so essentially, Turbo Boost is useless in games... might as well save the money for some other stuff (a Razer Orochi how abt that??? )

Hmmmm,...razer orochi, that's not a bad idea

anyone can give me a detailed analysis of why i5 is better in performance compared to i7 when it comes to games? lets just say we have enough budget for i7, leave out the financial bit of the argument.
my friend and i were in a discussion on this, he seems to be of the impression that since i7 is better in terms of performance, it should be no problem when it comes to handling games, although the games are not suitable for quad core procs, we can compensate by better performance of the procs. he seem to think that it is just that games do not occupy all 4 cores and hence no need to get i7 (economic argument).
can anyone be kind enough to explain to us? thx.

hmm, driver installation perhaps???

honestly, i ve never seen IDA (Intel Dynamic Acceleration, the predecessor of Turbo Boost, found in Core 2) kick in for other stuff besides drivers...


refer back to my posts...

games now are dual or tri core optimized, so when u re using a quad core, u re only using 2 or 3 cores out of the CPU...

further more, a i7 quad has very low clock speed (1.6GHz/1.8GHz compared to 2.4GHz-2.66GHz on the dual cores), so imagine when u re running a game, say dual core optimized, on a i7 quad, u re running only 2 cores on 1.6GHz (factor in Turbo Boost, u ve 2GHz maybe?), but on a dual core, u re getting no less than 2GHz depending on the model... so which one is better?

yes, i7 quad does have a lot of raw power, but whether u can utilize all the power depends on the programs that u sue...

as a matter of fact, i7-620M (2.66GHz) pwns the ass of i7-720QM (1.6GHz) hard in games benchmarks...

i7-620M is a dual core rite? what's the difference between it and other quad i7 CPU?

yup, 620M is a dual core...

actually, words like "i7", "i5" are purely branding... basically, i7 = hardcore, i5 = performance, i3 = mainstream, Pentium/Celeron = enrty...

the difference lies in the numbers and the suffix... u can see the difference in the list of CPU on the very first post of this thread...

hi guys..i want to ask something...

when we are playing dual core optimize games using core i7 quad cores, only 2 cores will be used and the other 2 will just be in idle state rite?

at this moment, do turbo boost will overclock those 2 working cores, making its clock speed higher?

i dont have the core i7, but it is nice to know about this. thank you
