SB vs. IB

the_director · 18 Apr 2012 at 22:05

So am I. I have bought a board designed to push chips to the limit, which is pointless if they simply melt. I may as well pick up a Sandy and aim for the magic 5ghz if Ivy is as bad as some are suggesting.

The estimated price between the 2 chips is £10-15 its not like its going to be a deal breaker....

£10-15? Have you even been looking at the Ivybridge price thread? The lowest the Ivybridge equivalent to the i5 2500k comes in at is £220 and that is rumoured to be without VAT as well. No way will it be sub £200.

I am talking about the price of the 3770k estimated price is £280...

If it is above £200 and clocks like some reviewers suggest - not great - then I will pick up a cheaper Sandy without doubt.

the_director · 18 Apr 2012 at 22:22

I'm talking about the 3570k obviously.

psychas · 18 Apr 2012 at 22:35

meh i will just get sandy form benching friends bined 2600k that can do 5.5 under water should do 5 ghz simpler cooling if something will buy new case and do only cpu cooling with 360 rad , for price of 3750k or there abouts.

Not tempted by a cheap 8150?

Ha! The near release of Ivy and the reviews about bad clocking and heat problems sending people into spirals of denial in the same way that people did when benchmarks showed 8150 was slow as hell unless multi-threaded...

I cant get my head round why Intel were comfortable with releasing mobo's for SB that where crippled in certain places.

Why cripple the PCIE bandwidth when I'm sure they could have just put PCIE3 on the mobo to start with?

Why does it matter? No card at the moment or for a couple of years will make use of bandwidth greater than what PCI-E 2 can offer.

Spenty They will be for 180-190f Otherwise you can buy one from Holland for ¬180 + 10f shipment and have it cheaper !!!
190 is with VAT

rossiboy001 · 19 Apr 2012 at 12:58

I notice the 1 day special offers havent included any 2500k or 2700k"s for a while , I suspect overclockers know something we dont perhaps . My theory , once IB reviews are released they will be unfavourable , a lot of people like me holding off will bite the bullet and put in sandys in our new z77 boards , and plan to sell those chips in a year when if IB have better stepping later revisions .
If they put offers up now for £150 i5"s or £250 2700k"s then ill just press the order button and have done with today
Its getting on my nerves sitting looking at boxes waiting a CPU .

I think you are uninformed, PCI 3 has been shown to be hugely beneficial for multi-monitor multi-GPU setups.

In fact, for people building a PC now who are intending on using multi-monitor and multi-GPU setups, it's quite stupid to not get Z77 because the benefit of PCI3 for that kind of setup is SO significant.

OrionTC · 19 Apr 2012 at 13:03

2500k is still a hell of a CPU even when IB comes out. from what i read the IB wont be leaps and bounds ahead in gaming performance anyway but will prob come with a premium price tag for a while.

imho...

The two graphs in this thread show how important it is to stay away from PCI 2 if you're planning on a multi-monitor, multi GPU setup, like I am.

The first graph, although poorly presented, shows that the user had a 50% increase in FPS just from going from PCI 2 to PCI 3 with 3 1920x1080 monitors and GTX 680 SLI on BF3 Ultra.

The second graph (from Vega), shows that he usually experienced at least a ~50% in FPS from going from PCI 3 to PCI 2.

Hopefully there will be more experimenting on this but it definately looks like you're be pretty stupid or iggnorant to not buy PCI 3 if you're intending on a multi-monitor multi-GPU setup.

EDIT: Question solved. I found SB does not support PCI 3 and I would be stupid to deny myself PCI 3 if the above charts from Dega and another forum member are true.

Those graphs show very unusual setps though - 3-way and 4-way SLI using the most powerful graphic cards around. It's not surprising 3-4 680's or 7970s could saturate the PCIe 2 bus.

But most users who crossfire and use infinity (like me) aren't going to have systems as extreme as that. Tests done in more conventional setups (2 cards) using the top cards of the previous generation (6970/580 GTX) should marginal differences. So people going for single or dual 7970s or less shouldn't see much difference.

SD2k · 19 Apr 2012 at 15:11

The first graph is 2-way SLI x16/x16 in both cases.

Sliver · 19 Apr 2012 at 15:50

This talk of PCI bandwidth saturation has got me thinking. Is there any way to monitor how much bandwidth you are using ?

Zeed · 19 Apr 2012 at 16:26

After everything i Read around forums and seen tons of tests of ivy. I decided to go sandy after all. I need as much mhz as i can get for 3D gaming. And i dont think my WC setup can cope with [email protected] .... Besides that they are not out on sale in ocuk yet. Saved 45f on my 10% voucher. And most likely i will wait for second revision of Ivy.
I dont need no PCIe3.0 for my GPU anyway
