Ivy Bridge-E Benchmarks

[ShintaiDK]

Well, if it costs them nothing, then I guess the cost/benefit equation plays out.

But really who is the target group here, it is not those who allready have SB-E, it must be those who is in the market for this segment but havent allready gotten the product yet(sb-e).
Maybe 'naive/not feeling the market', but I imagine that is a rather small segment.

I would bet you >95% of LGA2011 (desktop) buyers would be just as good of with LGA1155. But that never stopped anyone from spending money.

 

[ShintaiDK]

Yea, but we are only talking the E part here, right? .. 6 cores. For a second there I thought i missed something.

Its 6 and 10 cores. Same as the current SB ones so to say. You got a 4 and 8 variant. The 4 core SB-E is actually only 4 cores. And the 6 cores got 2 cores disabled due to TDP limits with the desired clockspeed.

So there is an option that you might see 8 cores within the desired speed with IB-E.

While sad, that makes sense, it is more about the marketing dept. than anything else: Look, new shiny numbers.. been with us ever since the GHz race.


edit : "So there is an option that you might see 8 cores within the desired speed with IB-E. "
- Well that IS good news then.. given an 8 core IB-E down the road, some SB-E owners might just have an upgrade path.

Oh, please. 8 core Xeon at 3.1GHz which is a 150W tdp part consumes less juice then 3960X with its TDP rated at 130W. With good binning they could release 8 core Xeon at 3.3GHz with 150W TDP, they just don't want to sell those chips that cheap. Maybe if they upped the extreme price tag to 2000$ we would see that. NV doubled the price of flagship products why won't Intel?

Because Intel doesn't get a Halo effect from doing so like NV does.

Wishful thinking. The 3970X is already 150W TDP.

And thats 400Mhz difference down to the 3.1Ghz 8 core. I doubt people want 8 cores on the expense that LGA1155 users would run in circles around them in 99% of what they do.

I just showed that 150W TDP part can consume less then 130W TDP part, they have 28W power headroom for that additional 200MHz.

They just won't sell their best dies for 1000$, period. The price would have to at least double.

ps. 3970X is 3.5GHz, 3.5GHz 8 core at 150W would be only possible on maybe one CPU out of the whole wafer if that.

No, you showed the average power consumption doing the complete toms hardware bench suite. Not to mention it was platform power.

So your graph is completely useless in this discussion and serves no purpose.

 

[nanaki333]

if it can give me even the same performance and come in ~100W (better yet, under 100), i'll be upgrading! or if they have an 8 core at the same TDP.

You're not refuting his point.

Gaps in average platform power underestimate direct gaps in power usage of the CPUs themselves.

Edit: to be more clear, tests within the bench suite that would mostly stress other components would underestimate the numerical gap between CPUs. Testing platform power as a whole underestimates the percentage gap between CPU wattage.

 

[Ajay]

Meh, going to pick up an i7-970 and wait to see what Haswell-E brings
We'll see how much of a difference 12-16 High performance FMA3 pipelines brings to the software I use.

He'll never admit he could be wrong, don't waste energy. Thanks for supporting me though.
Remember, there will never be an apu in PS4.(he said that with utmost confidence) Most of his posts are useless in every discussion and serve no purpose.

Next time let's please skip the commentary on other members, okay?

The i7-980 is priced the same as the 970, so you might as will go for the 980 instead if you can find one.

 

[Ajay]

Yes, but I'll get the 970 for a great price once a friend upgrades to Haswell this summer.
