so assuming i have "perfect" gpu and ram(which i know i dont), is my processor going to be able to run super mario galexy 1 full speed?
yea i know it depends on settings, but should i get a 6 core amd phenom
I already answered this, see below:
Quote:As for your questions about performance. Your new cpu should do fine but you will need a better video card. I recommend you pick up a 5750 or higher if you want to with ati or a 450 or higher if you want to go with nvidia.

No since nothing will be able to run that game at fullspeed ALL THE TIME with proper settings. You should still get excellent speed most of the time though.

No....we just told you that dolphin can only use 2 cores. Why would you spend extra money on a 6 core cpu after we told you that?
oh...
so im still a bit confuzed on one thing
since dolphin uses 2 core i can only use 1.7 of my 3.4 ghz?
You Just Misunderstand .. :S .. a Quad-Core CPU @3.4Ghz is 4-Cores fit onto one chip. EACH CORE is Clocked at 3.4Ghz . So Dolphin Will Use 2 Cores and each one will run at the Processor Speed . Dolphin Won't Use Extra Cores Like NaturalViolence Said , But also the usage of the two cores might not reach 100% depending on the game.
no. that's your processor's operating frequency. When you stress it (use dolphin) it will obv. work at 3.4ghz
a 6 core phenom processor wont be any 'faster' than a 2 core phenom because they both use identical k-10 cores and dolphin can only utilize 2 cores
(at most, there will be some minimal difference from varied l2/l3 size)
but a 4-core i7 will be faster even at lower clock rates because the nehalem architecture is much more efficient than k-10
ok so a 4 core 3.0 ghz cpu has a max total speed of 3.0
but each individual core can run at that speed.
But when there added it must equall 3.0 or lower
so a 3.0 ghz 2 core will preform at the same speed as a 4 core 3.0 ghz if its a 2 core program and the both have the same l2 and l3
Their are other factors that can effect application performance but you're mostly on the right track.
3.0 GHz is the clock rate of each core. If an application uses 2 cores it uses 2 cores regardless of whether your cpu has 2, 3, 4, or even 6 cores availible to be used.

What? You're making this to complicated. Let me try and explain it this was let's say your quad core 3GHz cpu is 4 cars that can go 30 miles per hour. You have two people you need to move from point A to point B (two threads in the application). But since cpu cores can only process one instruction at a time lets pretend each car can only carry one person. It doesn't matter if you have more than 2 cars since you only have 2 people it won't help you get them there any faster. If you only had 1 car (core) it would take you longer since you would have to transport the first person then come back to transport the second person. Does that make sense to you?
yea i get that part
but a 4 core 3.0 ghz cpu can run
(per core)
1 core at 3.0 ghz
2 cores at 1.5 ghz
3 cores at 1 ghz
4 cores at .75 ghz
4 cores total at 3.0 ghz(1 at 1.0 / 2 at .75 / 1 at .50 ghz)
etc.
it cannot run
4 cores at 1.5 (each) because it would go to 6.0 ghz which is over the max 3.0
Or are you trying to tell me that a 3.0 ghz 4 core can run each individual core at 3.0, witch adds up to 12.0 ghhz?
do you understand what im asking?

no. It doesn't add up to 12.0 ghz. That's just the operating frequency of all cores simultaneously.
How to explain it in laymans terms if you didn't understand naturalviolence's analogy.
You can't speed up the 9-month birth of a baby to 1 month with 9 different mothers. They all grow a baby at the same rate in their stomach.
All processor cores operate at the same clock frequency. It's not possible for one core to be slower than another on the same cpu silicon. They are the one and same thing.
If each core is operating at 3.0ghz, that's the clock frequency of the processor regardless of there being 4 or 48 cores, or even if just 2 cores are used and 4 are sitting idle (the idle cores are not running at 0ghz).
It doesn't add up but hopefully you understood.
CPU cores don't have individual clock rates just like 8 RAM cells on a stick don't operate at different frequencies (regardless of usage)
oh ok i get it, that baby thing explained it. i was also confused because one of my computer teachers told me that a 3.0 quad core had each core at .75 max. I was miss-lead.
wow that just completely changed my perspective. thanks
