How so? I thought clock for clock Haswell is about 10-15% quicker than SB, Making a 4.6 haswell OC comparable to a 4.9-5.0 SB oc..

I noticed a small bump in performance in a couple games, bf3 & crysis3, going from a 2500k 5.0 to a 4770k at 4.6

Let me put it this way:

When I play Guild Wars 2, in demanding scenes my frame rate would dip down to 30fps even with my i5 2500K overclocked to 4.70GHz. Let's say the Haswell i5 on the same clock give my 15% increase in frame rate...it would still be going from 30fps to 34-35fps. When you are looking at it this way, it IS a joke.

And there is much less chance of being able to clock a Haswell. Not like Sandy where 4.7GHz is a gimme.

It is clockspeed that bottlenecks GPUs.

Haswell is more efficient then SB and will get a few more fps out of a GPU at a given clockspeed but it is no substitute for out and out high CPU clockspeeds when dealing with several fast GPUs.

An extreme example is 8 Pack using 4 Titans and a 4960X @6.0ghz running 3dmark11, even at that CPU clockspeed he is still bottlenecking the Titans.

3 next gen cards will be a lot quicker than 4 Titans are now.

4.70GHz is about the max overclock that a Haswell would hit if using the right board, however the temp being too high is another issue, so basically 4.70GHz for Haswell is unrealistic for 24/7 use without delidding the CPU getting rid of the "heat trapping sealant" first (which can drop the load temp as much as 20C!)

So if all the leaks and hints are to be believed AMD has managed to create a chip on the same 28nm process as the 7970 that will be faster than anything Nvidia has, (690) be 25/30% faster than a titan, 23% smaller than a titans CPU, and still only cost £450.

Yeah ok I will believe it when I see it.

This can't be true. That's like saying an old quad q6600 at 4ghz will be better than a i7 920 at 3.5ghz just because it has higher clock speeds. This was no where near the case. Efficiency matters a lot as well. I do get what you are trying to say but the way you have put it is wrong.

 

[Orangey]

My god, will people stop saying 30% smaller than Titan. That's not what he said!!!

He said, using Hawaii as a base, that Titan is 30% larger.

Efficiency matters yes but gaining 10% in efficiency then losing 20% in clock speed is not the way to go when comparing Haswell and SB.

Having said that for a gaming setup with a single or two cards, Haswell is the way to go.

Ok 23% smaller ill edit the post.

Going by 3d11 physics scores, if you keep a 4770k efficient (high uncore, decent ram kit) it can be over 600mhz better off vs sandy.

Roughly a 3820 @ 5 ghz ddr2400 c10 will push around 12000 physics, while a 4770k @ 4.6 ddr2600 c10 is knocking on past 12600. For the sandy chip (remeber it also has quad channel memory) to match it would need around 5.3ghz while maintaining the memory speeds.

people clearly have percentage issues

I don't think I've seen any claims of 25% faster than a titan (well not really been looking) but its not unrealistic that it could achieve around parity. It comes down to the design cadence each company is using. The Titan is an old chip- its design finalized some time ago with all early stock going to the Titan Supercomputer. If Nvidia had decided 2 years ago (or whatever the required lead time) to revise and release an updated design on 28nm I am sure they too would be quite able to eek out extra performance from the same die space.

When will this thing be out?

It is not the physics which is the problem with Haswell, it's the low clockspeed which makes it hard to drive 4 cards to high fps.

For a single card on Haswell v SB it is a non contest in a benchmark, the Haswell wins every time. When you run 3 or 4 cards Haswell does not have the clockspeed to deal with them.

Oh I know that, I was aiming for a comparison between hw and regular sb, 3820 was only used as an example as its in the same ball park as a 2600k and i could remeber the physics scores off the top of my hesd, can't remember my old 2600k scores

3-4 cards, 3930k+ everytime

Just had a quick look at the results for a 4770k and 4 GPUs on the 3dmark benches. It seems to run better using cards like 2 GTX 690s or 4 HD 7970s than it does on 4 Titans. Having said that though there are not enough results to be sure but it does seem to be bottlenecking on 4 Titans.

These are the comparison tables from the leaked review which show 30% gains over various cards.

To add the fuel for the fun...

Next gen faster than anything NVIDIA has...

Kyle Hardocp

Faster than a GTX690?

Hmmm, now i'm interested.

You might argue dual gpu, but with 'titan price' a faster, cheaper dual gpu card will always get compared by the majority when its on a single pcb.

heh, this thread is entertaining.
