Hi all

Before I change my CPU (and possibly MOBO) I am going to wait to see what Haswell is going to offer.

Apologies for the basic questions...

So with the new CPUs, would you be expecting a new range of motherboards to come out from all the major manufacturers before or at the CPU launch date?

I take it anybody going for Haswell will have to buy an LGA 1150 socket board, or will Haswell fit into the 1155 boards?

Finally, while I am typing I may as well ask if anybody is expecting anything incredible to happen with Haswell (gaming and/or rendering -- performance wise)?

Thank you in advance.

Best
 
Haswell is really boring for higher end desktop, the heavily improved GT3 gpu is only going to be available on mobile parts, and the ones with edram and "real" performance are going to cost a freaking bomb, like £300+ for a low clocked mobile chip.. largely as the edram/bigger gpu on die will save power so they want it for the stupid high end ultrabook stuff. High end, basically similar/same clocks as Ivy, 5-10% clock for clock performance improvement, same quad cores, pretty dull really.

Unfortunately they've aimed Haswell mostly at fitting into ultrabooks better, they could EASILY do a hex or octo core part without the IGPU in mainstream pricing... but won't :(
 
Nice one -- Thanks

I appreciate that - Many thanks.
 
Does that imply yet another significant decrease in power consumption for slightly better performance? Something below 77W for a hyperthreaded quad core?

The TDP is higher (Because of the IGP)

You'll have to wait and see power consumption, but CPU it should use less.

That's the bit that has me sticking to my i5 750 @ 3.8GHz until Broadwell...or *sigh* even Skylake, as I really want to step up to at least a hexacore + HT at reasonable price.

You should be able to disable it though, correct?

I've been sitting on my i7 920 waiting for Haswell, but if its really that dull then I'm thinking I may as well stop waiting and go straight for something on LGA2011. Which tbh is 1366's successor anyway. A bit overkill for a games system, but so was 1366 at the time, and that proved to be a good investment in the long run.
 
Agreed, but for anyone that's been following it I don't see that many assumptions to be made. Unless there's a last minute surprise or they OC really well its looking pretty clear what they're going to be like IPC wise. Haswell is about efficiency, IGP gains, and ultimately Intel's ambitions in the mobile market.

Going to come down to how well it overclocks I suspect for most already on SB/IB.

Absolutely this! Intel's biggest problem seems to be that the previous gen of chips was really rather good :)

I think if Haswell reliably hit 5ghz, then with the IPC improvements over SB it'd work out a 20-25% boost for me. Anything less than that, won't feel the difference.

As for efficiency, the Tom's Hardware charts say 84 watts for a desktop i7 with 3.5 base speed. Might be wrong, but isn't that lower than SB and higher than IB?
 
Will wait for the full review with OC results but at the moment, don't see much of a reason to upgrade from my i7 2600K @ 4.5Ghz :(
 
I'm still tempted to get it for the usb3/sata3, though my cpu isn't showing any signs of age.

I'm playing Tomb Raider @2560x1440... all settings completely maxed out

Gtx 680 Load: 99%
Gtx 680 vRAM usage: 1971MB

i7 920 usage: 21% at 2.75ghz (even though I have a 3.2ghz overclock)

Looking at your sig, I wouldnt be looking at a cpu upgrade but a GPU one.

I'm running a [email protected] and a 5870@stock and honestly I'll probably upgrade my CPU before the GPU (likely with a 4770K if they hit 5ghz reliably), the reason being that I game at 1680x1050 and the 5870 still handles everything I need it to at that resolution with ease.

I'll likely not upgrade my GPU until I upgrade my monitor, and I'll not upgrade my monitor until 4K displays hit the mainstream (fed up of my desktop having a lower resolution than my freaking iPad).

Interesting. What games do you play with this?
