Pentium E5xxx vs E6xxx

Hi guys I have a few question about Intel Pentium E5xxx (800 mhz FSB ) and E6xxx (1066 Mhz FSB ) series.

First, I have heard that the E5200 @ 2.5 ghz can reach 3.8 ghz on air easily with stock fan, and the boundary is somewhat 4.0 ghz. The question is, if I get an E5800 @ 3.20ghz, does the E5800 more stable at 4.0 ghz and also cooler than the E5200 at 4.0 ghz?

Second, what is the E5800 boundary ? , also the E6800 ? Are they just have the same overclocking boundary as E5200 or they better ?

Third, how better does an E6xxx compare to an E5xxx with the same clock speed ( like E5700 @ 3.0 ghz compare to E6600 @ 3.06 ghz), 10 % ?

Finally, why Intel give their CPUs such stupid and duplicate number like Intel Pentium E6600 @ 3.06 ghz and Intel Core 2 Duo E6600 @ 2.4 ghz ) ?

Not necessarily. I have an E5200 (M) and 5700 (R), and they do seem to produce almost the same thermals at a specific voltage. My 5700 has a higher stock voltage and VID than my E5200, so it's understandable that the 5700 would be hotter. I'm not sure if they just increase the VID to get higher speeds on these things.

But your mileage may vary depending on the chip you got.

Not sure with this one.

I couldn't quite remember, but I think Tom's did an article comparing the less cached Core series to the more cache ones. The difference is really really marginal, I think it was less than 5%. As with the bigger FSB, I think other sites did articles on these and the difference is also marginal.

There is a difference, but you'd probably barely notice it.

Don't know about that stupid name, but the first E6600 is a 45nm and the next one is a 65nm. (A really dumb-ass move)

why bother overclocking either? both are low end dual-core chips - end of the day your still stuck with TWO CORES

stupid naming scheme? ONES A CORE 2 SERIES ONES A PENTIUM DUAL CORE - its clearly a different series

Maybe because the guy is quite content with a Pentium Dual Core, or wouldn't have the budget to upgrade to something bigger.

Don't know why the guy needs 4.0GHz, just trying to help.

You're right

I'm thinking of buying a top intel LGA 775 dual-core for Starcraft 2. I'm was trying to get 50-60 fps with 4v4 Comp. Currently, my E2180 @ 2.0 Ghz O.C to 2.7 Ghz and still not enough. So I wonder a 4.0 Ghz intel dual-core could do the job ? ( Quad core CPUs are not optimized with SC2, that's the main reason )

Also, does this board :ASUS P5G41C-M LX http://www.newegg.com/Product/Product.aspx?Item=N82E168... , good for overclocking to 4.0 Ghz ?

My current spec :

ASUS P5KPL-AM SE
Intel Pentium E2180 @ 2.0 Ghz O.C to 2.7Ghz
2x1 GB DDR2 PC6400 Kingston
ASUS ENGT430

Hello

I am from Pakistan like you. You have a few options:

pentium dual core e6500 new Rs. 7,100
c2d e8400 used Rs. 8,000
c2q Q9300 used Rs. 11,000

Check out http://www.cpubenchmark.net/cpu_list.php for benchmarks of all the above.

I don't know whether you will see any difference upgrading to a faster dual core chip. Maybe starcraft will work faster with an e6500 or an e8400 compared to your current cpu. But the best upgrade would be to a quad core chip.

Also that mobo isn't overclocking friendly. I think you can only change the fsb not the cpu voltage. Its not much different from your current mobo. You can install any of the chips mentioned above on your current mobo.

Thank a lot buddy. That list help me a lot. However, I will buy an E5700, since it got a good range of multiplier (6-15), but a lower FSB compared to E6500, but still win in default performance, price and overclocking. According to http://www.cpubenchmark.net/cpu_list.php

And about that mobo, i think you're right. If I got a chance to upgrade to a better mobo, which one is the best mobo for the money ?
