SB750 vs 700 vs 600

i know my answer is probably somewhere in this forum but,
could somewhere list out the difference between the 3?

Also, which is preferable for overclocking?

concerning the chipset i would also like to see easily and quickly
what are the differences between 740G, 770, 780G/M/V, 790FX/GX/G/V/X

Thx.
 
Phenoms have had a hell of a time getting decent OC's until AMD released the SB750, which gives overclockers the ability to enable use of Advanced Clock Calibration.

Upon using a Foxconn mobo with the SB750 southbridge, Anandtech.com noted easier and higher overclocks, to the point of Gary Key saying "In all seriousness, ACC works...extremely well" (Link 1, Pg. 6 "Final Words", Par. 4, Sent. 2). Read the articles for numbers/charts and a better understanding, but the bottom line is that it is entirely worth it to get an SB750 mobo and I believe there is a very small price premium to get one.

Maybe so for phenoms, but what about X2 dual core?
From the prices i see, 790FX/750SB boards are limited to 3 choices (asus, DFI, foxconn) and are the most expensive ones.
Worth it over say a 770/700sb ? (ex: asus M37A8)

now what a 790fx offer in plus value over the 790gx or 770 or 790x etc? (besides better OC for phenoms)

My understanding, besides ACC that allows phenoms to OC better, the 750sb corrects a single flaw from the 700sb which is raid 5 (who cares?).
 
SB600 also has issues with AHCI support of sata drives under Vista. Same thing may or may not affect the SB700 too.

And sorry to hijack the thread, but anyone know of comparisons of the above with some of the cheaper Nvidia chipsets (eg SB700 (w 770 or 780G) vs Geforce 8200?). I'm interested in anything *but* graphics performance (like the above mentioned overclocking pottential and any random bugs).

I have a Biostar TF8200 A2+ mobo. It ran an X2 4000+ 2.1 Ghz oc'd to 3 Ghz, would go higher but too much voltage for my taste...

Right now I have a Phenom 9850 non-BE (2.5 Ghz) running in it, oc'd a straight 10% across the board (CPU, RAM, HTT, etc). I have a pretty weak HSF on it, so haven't tried to go higher - it would get too noisy.

The Admin over at Rebels Haven has a 9950 (2.6 Ghz) running at 3.4 Ghz on a Biostar TF8200 A2+.

 
Thanks, I'm deffinately considering a TF8200 if my 770 / SB700 ASRock A770CrossFire doesn't turn up (seems to be 0 stock in the UK 🙁 ).
 
Newegg has 790GX boards for $100 which have the SB750. There are boards for as low as $50 with the SB700, but I assumed you were using a Phenom when you posted this thread and I responded as such. You mentioned a wiki article, so I did some quick research on Wikipedia and found that the 790GX chipsets are made on a 55nm fab process (less heat), the 780G (also a 55nm fab) and up support Crossfire (worth a mention), and the 770 and up support a max FSB speed of 2600MHz (def. important - 740G and back have a max of 1GHz or less).

SB600s are known for having funky ACHI issues with Vista, SATA support is limited to four ports, and they have issues with Phenoms. I know you're talking X2's, but if Rage3D had to underclock a Phenom to be stable, that can't bode well for X2 OCs. SB700 fixed most of the issues with SB600, but had some vague "internal clock generator malfunction" issue which was solved with the release of SB750.

The price premium is there but at worst it's $40 when comparing the 780G+SB700 mobos to the 790GX+SB750. It's up to you whether you spend, save, or reallocate the $40, it could buy a better CPU cooler, nicer fans, etc., you could spend less on the build, or you could have a potentially more stable motherboard.

It's getting late, otherwise I'd get into the Nvidia chipsets...maybe tomorrow after work.

AMD 700 Series (gammaray linked this too)

IGP Article mentions Clock gen. fix

Rage3D briefly discusses SB600 - SB750

AMD 780GX's
 
From what I've read, ACC doesn't work with non-Phenom CPUs. So X2's won't benefit from SB750's ACC. If you don't plan on getting a Phenom anytime soon, don't bother with SB750. SB700 should work just as well. Now... if you DO plan on getting a Phenom, SB750 is no-brainer. SB750 is the key ingredient to make AMD platform even relatively competitive.
 
Something i don't get tho is, why are motherboards are evolving to be build with an IGP ??? imho, that sucks. Putting an igp on a board are ressources and cost that could have been spent elsewhere. Most of us are gonna buy a graphic card anyway, i simply don't get that move. To make things worse, retailers are invaded with 780G and 790GX boards. I wish they would simply replace the GX boards with 790FX/750sb and sell them cheaper.

(Motherboards aren't built with integrated processors, integrated hard disks or integrated memory sticks, so why the integrated graphics?)

Same reason for integrated sound, Ethernet, hard drive controllers, etc.

I prefer the integrated graphics, just because they make every computer usable even without a video card. The cost increase is minimal, so why not.
 
There are some 790FX with SB750. You just have to look a bit harder.

I think 790GX is a great chipset, despite the IGP. 790FX doesn't really offer much more features unless you're dying to blow $$ on 4-way CF. Other than that, IGP are pretty nifty at times. Especially when you're upgrading your video card and need something to output video/ watch movies to tie you over. No need to go out and spend $30-40 on spare GPU.

3 choices...
as opposed to 50+ for 790GX or 780G

I'm guessing (don't really have a clue) that the ""Flagship 790FX"" will soon be making an appearance with South Bridge 800.

Actually, I saw a post somewhere (could be XS?) that said March/April to coincide with the new, new Phenom II that some have taken to speculate as the next AMD 'FX' microprocessor (which I think is just the Phenom II 945 AM2+/AM3 @ 3.2GHz with the IMC/NB at 2.2 or 2.4GHz) with HT3.
