Default Core 2 Duo, which is better?

I have 2 CPUs Core 2 Duo E7500 and a C2D E6850 which is better??? hmmmm

1.) E7500 has less L2 cache 3 MB and runs slightly slower 2.93 GHz/1066 FSB but has supplimental SSE3 and SSE 4.1, newer 45nm Wolfdale technology.

2.) E6850 Older Conroe chip @3.0Ghz but has 4 MB L2 cache/1333 FSB but no SSE 4.1?.

the E7500 is better , Lithography is 45 while other is 65 ... : so it will be colder
Bus/Core Ratio is 11 compared to 9 : so cpu makes more "works" with the datas and instructions before it send or received some datas to the others elements

of course SSE3 and SSE 4.1 will make big difference with video and game softwares

his pc already have a E6850 : http://forums.hardwaresecrets.com/in...5942#post25942
may be he saw cpu at his " Lee's Bottle Depot" or "Free Geek Vancouver"
by the way he shoulld see if he has latest bios before replacing cpu :

off topic : intel mobo are not good but support and updates are .

In general, the E7500 will be a better pick. @jcjenny: Just a reminder. The SSE4 instruction set will make a difference only if the program is capable of using these instructions; if the program doesn't make use of them, you will have no performance increase.

Thanks for the replies

mainly I use my PC for older 3D games,web browsing burning CD's to my music library, listening to internet Radio

I'm gonna try both of them for a while see which is better I have the E6850 installed right now and I have the E7500 as an extra processor that I will try later.

I found the Intel white paper on ISA it was really dry reading but still interesting it makes mention that SSE4 accelerates media processing, 2D applications, 3D gaming, more efficiently processes DWORDS ,QWORDS which are related to 64 bit processing and gives specific examples of improving or accelerating enterprise class network storage capabilities actually eliminating network accelerator cards as well as data mining search improvements.

I posted the white paper in PDF if you like a nice dry read.

tomahawk,

As explained, these instructions only increase performance IF the program uses them. The increase in processing is not automatic.

of course , but 4 or 5 years later these instructions are nearly always used in games , video tools or vga drivers .
newer cpu have also some optimisations to handle old instructions better than previous cpu .
by the way , even the E6850 is not fully used , so the argument : "Lithography is 45 while other is 65 ... : so it will be colder " should make you swap cpus
moreover because your pc will eat less electricity and waste less energy

Ahh yes I see Ok points well taken thanks
yea I like the energy efficiency idea ,the 45nm Wolfedale has the new Hi K metal gate technology which was a big breakthrough for Intel.

Default E6850 vs E7500 Core2Duo

The verdict is in as far as I'm concerned after running the Core2Duo E6850 3.00Ghz /1333 FSB/ 4Mb L2 cache for a month or so to get a good feel for it in everthing that I do on a PC.A few days ago I just switched to the Core2Duo E7500 2.93Ghz /1066 FSB / 3Mb L2 cache and there is a noticable difference in performance at least for me with Vista x64

My system runs much smoother now with the E7500 even though it is slightly lower clock speed and slower FSB it still feels much quicker than the E6850 and runs much cooler.

Just in case anyone was following this thread and was wondering what the outcome was
