Sandy Bridge E vs Ivy Bridge

[bridito]

"Ivy Bridge", will be up to 37% faster, and that their energy consumption will be up to 50% lower.

I don't know this guy, he's not my cousin, and I have no idea if he got this out of his hat, but I've seen this 37% figure quoted before and with all due respects I think that the estimates of +5% might be seriously whacked.

I've also seen a fair amount of "rumors" that IB will be LGA1155 with IB-E coming out six months later (or so they say) on LGA2011. Is another socket in our immediate future? I'm not so sure.

37% faster than what? Energy consumption will be 50% lower than what?! And are we talking about the same CPU, or is this and/or? What portion of this increase in performance is due to IPC, and what portion is due to increased perf/watt (higher clockspeeds for top bin CPU). ST or MT? What portion of this is due to the faster GPU, and has nothing to do with the CPU?


Nehalem --> SB was 10% to 20% IPC increase (disregarding new instructions, of course) as we saw here:

http://www.tomshardware.com/charts/...parison/All-time-based-values-added,2779.html

I honestly don't even think Haswell will get much more than that in legacy instructions. IMHO, Haswell's magic will be the new instructions it adds.

 

[bridito]

Here we go... I knew it was out there somewhere...

http://www.tcmagazine.com/tcm/news/...ing-six-lga1155-boards-pci-express-30-quarter

MSI's LGA1155 PCIe Gen3 motherboards are claimed to be 'future proof' which means they will receive BIOS updates that will enable them to support Intel's Ivy Bridge CPUs which are planned for a March/April 2012 release.

OK, here is how we resolve this: I'm right and you're wrong. OR I'm wrong and you're right. Do you know where the proof of the pudding is? It's always in the eating. You can keep insisting that IB is going to be a sideways step and I can keep insisting that it's going to be a massive leap forward until then. When the benchmarks come out then we can pick this up again and whoever loses owes the winner a beer. :thumbsup:

Intel was talking about transistors made with the new 22nm Tri-Gate and not about next gen CPUs Ivy Bridge.

People have to understand that Clock to Clock SB and IB will have almost the same CPU performance.
Now if Intel will release a 3.6 or 3.8GHz quad core IB, then yes that CPU will be faster than a 3.4GHz Core i7 2600K.

 

[bridito]

Again...

I'm right and you're wrong. OR I'm wrong and you're right.

Looks like I might be getting a lot of free beer when IB is finally out!

More likely you'll be the guy paying for the open bar

Exactly.

But we can safely assume that IB will be released with much higher clocks than SB simply due to the 22nm process.

 

[Edrick]

I think the same thing. I am sure they will be able to get a ~5-8% IPC improvement in Haswell. Nothing earth shattering. But the new instructions in Haswell will be a game changer in my opinion. I have spent some time going over the Intel papers on these and I really can not wait for this cpu to be released.

 

[bridito]

No prob. If I lose I pay. I have more than enough bar money given the fact that I work and earn while "many others" are peeking around corners trying to shoot monsters.

 

[inf64]

I will have to agree,

Ivy Bridge will have minor improvements in the CPU micro architecture over Sandy Bridge (AVX extensions and uArch optimizations) and clock for clock will have almost the same performance.

It is in the iGPU department that we will see the biggest differences with up to 16 EUs (12 for SB), PCI-e Gen3.0, DX-11 support and more.

Because of the 22nm process along with better power gating in iGPU and in Memory, power usage will be much lower both in idle and load than SB.

And you would be correct.
0-5% improvement. I did the analysis of the original coolaler's results here. I came to the same conclusion. IB will have higher Turbo and probably much better power draw numbers.

LOL, make sure your income will increase before you upgrade, or you might have more in common with those silly gamers, than you care to admit ?

Hey, I'm sure that all the gamers would see my addiction to certain reality tv shows as the same completely useless waste of electrons as I see their pointless and puerile playing. Everybody needs their own particular fix.

 

[Mopetar]

IB will be a die shrink of the current SB parts. IPC won't change, but the chips will be able to clock higher or draw less power at a similar clock speeds.

The main differences between the two chips is that SB-E will be targeted at the high-end market and professionals. IB will be more mainstream. SB-E will have more PCI-E lanes, more cores, etc. that are more useful for professional applications or hardcore gamers.

 

[greenhawk]

Whoever said that IVB wasn't going to come without any architecture changes is wrong:

Their will be some, but the main change from my reading for the IB release is the 3D transisters that are ment to mean lower than normal power needed for the otherwise normal step change.

What this means in end user performance changes is to be seen as it looks like some will use the lower power to get better TDP while others will have faster clocks at the same TDP.

The increase in the onboard video is expected, but as to it's worth to mid/high end users is to be seen.

 

[greenhawk]

faster than what?

if the details are not against the previous version of the chip, then the artical (and site) really are not worth reading. Heck, they could compair to a 486 and get good numbers, but anyone worth their salt will just ignore them in future.

 

[greenhawk]

won't IB end up undermining the sales for SB-E?

And sorry for my foolishness, but if Ivy Bridge draws less power, it's not going to overheat as much and in turn, overclock better?

So who would want to jump on SB-E if it ends up costing 3-4 times more?

re sb-e sales, IB will not effect them as SB-E will be priced above them. Inital costings of the inital SB-E is $300/$600/$1000. IB is proberly at the same price points as the existing SB CPUs, with proberly a short term extra for being "new".

As to IB overclocking, that is one of the reasons people are hoping it is as good as expected, but then intel will use some of that power savings to have CPUs that run at a lower total power just for better marketing reasons.

As to who wants SB-E, anyone with money and wants the best performance. Regardless if it is not cost effective.

What will receive IB sooner? Desktops or laptops?
I want to buy a laptop with Intel Ivy Bridge and Nvidia Kepler

2: SB-E for socket 2011 will be released 3 to 6 months prior of IB.

3: SB-E will have 6-core CPUs when SB and IB in Socket 1155 will top up to quad (4) core CPUs.

4: After 3 to 6 months of IB 1155 introduction, Intel will release IB-E for Socket 2011 (4-6 and perhaps even 8 Core).

It will be the same that happened with Core i7 920/30 at Socket 1366 and Socket 1156 Core i7 8xx.

#2, going from a post/information release a week ago, SB-E is ment for about a march '12 release instead of the original q4'11. IB from a month ago was set for April '12. So looking like a 1 month release between them.

But then yesterday I read that intel is trying to get something out this year but are looking to be a butchered version of what has been promised as the 1366 replacement.

#3, SB-E does have a 4 core version at the lower price end. Ment to be comparable to the 2600 IIRC. Not sure if that is the k or non-k version.

#4, it will not be in intel's interest to have sb-e out for only a few months, so ib-e will be in '13 I suspect. Espically as the IB has been pushed back a few months to allow for 12 months for SB given the motherboard issues.

Though personally, if SB-E keeps getting pushed back, they might as well skip it for IB-E instead.

 

[tweakboy]

It's 15nm after 22nm I think.

Nice.

 

[Edrick]

The 4 core is going to be locked, just like the current non-K versions. So if that holds true, then they should be able to be OCed 4-5 bins higher, just like current non-K SBs. However, there is talk that s2011 will allow BCLK overclocking, so who really knows until we see some samples.

 

[AtenRa]

Exactly.

But we can safely assume that IB will be released with much higher clocks than SB simply due to the 22nm process.

Im sure Quad core IB will mach Quad core SB-E frequencies (3.6GHz ?? = same performance ?? lower power usage, cheaper both in CPU and platform)

 

[Edrick]

I am thinking higher than that. Quad IB should push 4Ghz stock and well into the 5's (close to 6) max OC.

 

[Nemesis 1]

Exactly.

I don't think so . I think Intel would use the same clocks and take advantage of the power savings as Being GREEN. There would however be the higher clocked K models that would enjoy a 18% clock increase befor it reaches present 2600k power usage . thats actually a huge amount of clock room . SO I look for Only the the higher end Ivy bridge to be clocked higher to deal with BD if BD is competitive . We could see a based clocked IB K model at a 3.9 ghz with 4.5 ghz turbo . That = todays 2600k in power usage. Thats about the best we can hope for other than minor changes that add up in % of performance gain at same power usage.

Let's not forget that IVB's initial SKUs will have an upper bound on stock frequency/performance based on the pricing/performance tiers set up where SNB-E represents high-end/enthusiast and IVB represents a more mainstream product. And we already know where SNB-E lies based on released Intel roadmaps.
