Why is Sandy Bridge "not promising"?

Paying more to overclock is almost an oxymoron for me.

Pretty much sums it up for me. Price VS performance. It is very satisfying being able to spend half a much and get the same performance or close to it.

Very, very few people in the grand scheme of things are going to pay a premium just to be able to overclock if this turns out to be the case.
 
Sandy Bridge will be fine... It offers around 5-10% increase in performance at the same clock while consuming less power. Yes it sucks that they limited overclocking but the unlocked versions should overclock like crazy. We probably wont see a value chip like the i5 750 was though. Many people here though went for the more expensive 920 so i dont see it being that big of a problem really. Low end overclockers will go to AMD, high end for Intel.

On Bulldozer i ain't so sure yet. I hope it turns out good, AMD needs a competitive CPU architecture. Its been ages since they were close really. Phenom II was good, but was late, it should have launched when the original Phenom launched.
 
My i7 920 at 4.2GHz + 6GB ram, can't see the point in going Sandybridge, this set up should last a while yet. There's not many games out there challenging it now, my GPU is a GTX470 850:1700:200 eats everything l put it through, so the only thing l will update is the GPU, unless l go Sli.
 
I think half the reason some are saying sandybridge is not looking good is more to do with how some people built it up in the early days expecting way too much from it and now the reality is coming closer well it's easier to blame the chip then people admit they got it wrong. I will look at sandybridge but won't be buying anything till both it and bulldozer are out but i do have this feeling i am gonna go with amd regardless this time just fancy a change.
 
This is the issue though by the time AMDs BD releases it maybe Summer/fall 2011.... and then by that time you might as well wait for the replacement X58 and updated core i7 Sandybridges which is due fall 2011.
 
Then i will compare them as well lol bulldozer is bringing a lot to the table and if your upgrading next year then waiting for it rather then jumping on the intel boat because they are out first might not be the best thing to do.
 
Yeah no major rush your systems good to go for a long time yet...

For everyone its a different case and guess all depends what current specs you have, my Q6600/GT330 gpu combo needs a total refresh me thinks besides once BD/newer SB arrive few months afterwards is ivy bridge from intel, theres always something better/faster/cheaper 6 months down the road :)
 
havent really read the thread, but am i right in thinking the sandy bridge will be equivilent to our x58 now, and the ivy bridge will then become our new x58 so to speak, so when sandy bridge comes out it should have a 30% increase in performance across the charts respectively compared to current generation socket 1156 ?
 
Ivy Bridge is not the LGA1366 replacement. It will be a die-shrink of Sandy Bridge, probably available for both the mainstream LGA1155 and high-end LGA2011. Depending on when they plan on releasing LGA2011 and Ivy Bridge, that socket might jump straight in with Ivy Bridge rather than starting with Sandy Bridge.

so by die shrink, ivy bridge will be able to be faster? or at least a lot cooler, also it wont have the integrated graphics will it, so shouldn't it have a lot more room on die for more cores etc

Die shrink doesn't usually come with much of a clock-for-clock perfromance increase. For example going from i7 920 (45nm, 4 core) to i7 980X (32nm, six core), in single threaded applications and at the same clockspeed the two performed near identically.

As you mention, the main benefit of a die shrink is reduced power usage (which can allow for higher stock clockspeeds and more overclocking headroom), and of course some room to throw on a few more cores (like they did with Gulftown).

As for integrated graphics, I hear that ivy bridge will have integrated graphics even more powerful than sandy bridge (for the mainstream parts at least).
 
The standard Sandy Bridge chips have a locked single internal clock tying up every bus (USB, SATA, PCI, PCI-E, CPU cores, Uncore, memory etc) so a X% overclock will result in all bus's be overclocked X% and some cannot handle more than a a few % like the USB and Sata. This is apparently and according to...

http://www.bit-tech.net/news/hardware/2010/07/22/intel-to-limit-sandy-bridge-overclocking/1

Apparently to save money with motherboard manufacture, although seeing as there is no USB3 support on the chip along with a few other things these will need to be added by mobo makers, probably not resulting in cheaper mobo's.

Theres also the notation it is so split the market up and charge a premium on OC'able chips, if true I guess a similiar setup (from a marketing point of view) to the standard phenoms and the black editions.

The article above also questions what the mobo's are going to be like. With next to no OC potential for the majority of the chips (and the market) wheres the incentive for mobo makers to make the premium boards!?
 
The multiplier unlocked chips (K series) will allow for overclocking - as the bus speed can remain the same (100MHz) while the multiplier is increased to provide the overclock. Looking at this sample - overclocking on these chips is going to be nice. Also, these chips will command a premium over the non-K series chips, but looking at this price list the premium will not be particularly high ($11 for the quad core i5).

As for premium motherboards, if a chip is overclocked to this level it will need enhanced power regulation and onboard cooling. Also features like PCIe x8x8 SLI/CF (and x16x16 with a nf200) will be offered on the higher-end boards.
