NP8660 Processor Conundrum

I'm currently considering the 2.8 GHz and 2.53 GHz (25w). I'm weighing the pros and cons, and wanted to know what people thought

2.8
PRO: More powerful, useful for gaming
Morw Futureproof

CON: More expensive
higher power consumption

2.53 (25w)
PRO: Lower power consumption
cheaper

CON: Less powerful


Really what I'm asking is whether or not I'm going to regret not getting a 2.8 processor.

 

Probably, If you are anything like most people on this site you always want something faster and more powerful after a little while.
You could also upgrade in the future if you want,but I say why wait.

 

You can get 2.53 now.it's not very different compared to 2.8 and change it later when some thing better comes out.

 

But isn't changing processors really difficult?

 

Look at the benchmarks and decide for yourself-

Is there a temp for the 2.8 CPU to compare with the 2.53?

 

From people's benchmarks it looks like 5-10 deg difference in idle and 15-25 deg difference at load

 

It can be if you're never done it before but it isn't too hard on modern laptops. Now if you go back 5 years or so, it was a real pain in the butt just figuring out how to take it apart to even get to the processor, much easier these days.

 

That's kind of a lot, I'm glad I went with the P9500.

 

Still, it's just from two units

 

P8400 ftw.

 

While the cooling system on the NP8660 is yet to be widely tested, I'd rather place a 25W CPU in there just to be sure that I'm not pushing the cooling system too far and giving those extra heating resources to the GPU.

With a P9500 you get most of the pros of the powerful T-series for less of the cons. Besides why not be that little more environmentally friendly by having to wait a few more milliseconds...

 

its pretty much just disconnecting a few cables, unscrewing the heat synk, unlatch the.... securer? and voila!

 

In addition for the comparison, My P8600 2.4ghz scored 9030 on my out of the box 3dmark.

 

250 points for 0.13 ghz difference, and 200 points for 0.27 ghz difference.
Oh, I guess the 6mb cach thing plays a part..
Now we need to check how it runs crysis.

 

What?????????

 

whatever you do, dont go for anything lower than the 2.5 though r you will be left with only 3mb cache

 

I went for the 3mb 8600 2.4Ghz one. The price difference it too much for 0.13 Ghz. The benchmark difference is too small too. Besides if there is a new quad ever released that would work on this, i save money and get that when/if it is released.

 

clock speed is one of the last things you should look at. cache is more important. 3mb-->6mb imo is like the jump from single core to dual core.

 

That's a little bit of a stretch.

 

Yeah right :laugh:

 

I added a poll. above ^^^^

 

2.53 fo shizzle

 

P8400 300mhz is not going to do you much good for anything and its not worth the money.

Plus im sure there will be a way to overclock it to 2.8 at some point if you want.

The G50V that I just got has the P8400 and with 2 mouse clicks it auto overclocks the cpu to 2.8ghz, with setfsb I was able to get it over 3ghz.

 

Do you really want to overclock this notebook?

Gophn's going to have to sell you a huge cooler.

 

Not for this machine. Any Quad-core with a 25W-35W core is a generation or two away still for now. Face it, you're stuck with your duo, which isn't a bad thing as most software wouldn't fully utilize the quad at the moment.

 

Nah I am ok. I hope to keep this for about 3 years so if I need more power I will just get another c2d supported if there is no quad available.

 

Won't getting the 2.8 Ghz proccessor mean high overclocking as well? I am definitly getting the 2.8 Ghz proccessor. It's kind of in exchange of not getting a 17 inch screen.

 

yes right, since any cpu with a descent cache (6mb or more) will have a descently acceptible gaming clock speed.
if you only cared about clock speed and whent for the 2.2ghz because you thought it was not worth the extra money for the 0.3ghz more, you could be quite surprised.

 

My comment wasn't about that cache is more important than .3ghz increase, I agree with that. My comment was about between the two cpus (P8600 - P9500) that the difference in speed/performance (not Ghz) will be like the jump from single to dual core, as you said.
Unless of course I misunderstood you.

 

I'm confused; your first sentence seem to be against the P8400, but the rest of it seems to be recommending it.

 

Kevin, Vicious forgot a coma after P8400.

 

Oh, I see; with a semicolon after the P8400, it makes perfect sense. In all honesty, the only reason I got the P8600 was so I could sleep at night.

3dmark CPU scores from the results posted in this topic:

P8600: 2161
P9500: 2333
T9600: 2553

The doubled L2 cache doesn't seem to give the 9500 a huge advantage over the 8600.

 

Lower power consumption + slower clock = less heat.

Get the slower proc, wait til you get annoyed with it, see if you can overclock it.

That way you get both... eventually =]

 

OK, you guts convinced me, I'll get the 2.53.

 

That should say T9600 right?

P8400 @ 2.2ghz 3mb l2
P9500 @ 2.53ghz 6mb L2
T9600@ 2.8ghz 6mb L2

Is that correct?

I would've expected a bigger difference between P8400 and P9500 (clockspeed slightly larger, plus cache difference) and a smaller difference between P9500 and T9600 (smaller clockspeed difference, same cache), it's kind of weird how it falls just in the middle of the two.

Probably just illustrates the lack of effect cache has on 3DM.

But 3DM isn't everything! It's true.

Oh and while it's true that with a faster CPU you get a higher end clockspeed, the change in clockspeed (amount you overclock by) tends to be smaller. This is for a few reasons, such as:
1. Diminishing returns, the faster CPU has less head-room
2. Faster CPU has a higher multiplier so overclocking has to be done in larger increments
3. Faster CPU runs hotter and requires more power, so you're already pushing the thermal and power requirements, whereas with slower, cooler CPU you have more headroom.

Among other things.

Hey Vicious tell us the PLL you're using! Someone test it with the M860TU and see if it works!

 

Safe to say it was a typo, the only other P series heading out is the P8700. Too bad, a P9600 would solve this thread issue very quickly.
