Anandtech Review of Ivy Bridge is Up now! Other sites added

I guess I'm the only one who thinks that 3.9GHz at a mere 0.9v is impressive.

That's 300MHz faster at way less voltage than my current proc.

 

[blckgrffn]

Personally, I am excited to see what IB can do with 8-10C ~4.2-4.4ghz. If the volts can stay low, you could get some AWESOME performance with a much smaller die vs. SB-E.

Not to be argumentative, but couldn't you just look at a SB @ ~4.5-4.7 ghz, subtract ~10% power and be pretty confident in the numbers?

It doesn't seem like it really changes the SB-E vs SB/IVB equation much, does it?

If there was a six core IVB, then we'd be talking about some excitement (on my part)

Yes, that does seem to be a rather intriguing finding... I'd be good with that for 24/7 clocks and I'd take the big power savings over the 2600k as well. I think I'll leave the 2600k in its box until I see the MC deal on the 3770k deal.

People expected Ivy to do 5.3Ghz daily on air without issue and if it was an exact die shrink of sandy it would have but IPC and 3D Transistors changed all that

 

[jacktesterson]

No thanks.

I've got a 2500k that will hit 5.0 GHz with more juice.

Will keep it.

 

[MPiland]

So again, should I go with IB? I mean it still sounds pretty solid and I think I could be happy with 4.5/4.6 ghz. I'm not going to be doing any benchmarking, just a lot of 3D modeling.

Its going to be the same price as sandy bridge so ofcourse you should.

 

[Lonbjerg]

No offense but even review editors are noting how much more difficult IB is to overclock compared to sandy bridge. The plot graph at this very site shows a 90C temperature at 1.25V and 4.5ghz....I guarantee that SB would have better results than that. Heck, my 2600k does not exceed 60C at 4.8ghz. That is heavily overvolted as well.

Overclocking isn't guaranteed for any chip, obviously. IB is better if you dont' care about overclocking.

Nice way of ignoring his inclusion of "performance"...if he hadn't included that in his post...you might have had a point....but alas...

I guess the is fallout from Dulldozer...it's not about the IPC and performance...it's about the Mhz!!!! :sneaky:

 

[blckgrffn]

Interesting in Anand's article - why didn't they just face it off against the 2700k? Then they could have done their typical review and, arguably, an IPC piece in one go. The 3770k and 2700k are both 3.5 Ghz CPUs, right?

Based on the CPU lineup chart in their article, it also appears that the 2600k SKU is the one going away? Doesn't that make the 3770k vs 2700k lineup make even more sense?

I know that the 2600k is more prolific IRL, but it is trivial for most to increase the frequencies that trivial amount if they want...

Maybe the most interesting take away from Anand's review is that if Trinity is as much of improvement to Llano w/regards to graphics as IVB was to SB, Trinity is going to blow IVB out of the water in that regard.

 

[Olikan]

It's a 'tick'. What else did you expect?

a lot more overclock?

 

[BD231]

lol if I can hit 5.3GHz on Ivy I'll be the one laughing.

Considering how close dons 4.5Ghz comes to my 5.2GHz scores it would be pretty nice.

For the sake of advancement I do hope you get 5ghz. Don's Ivy gets outperformed by identical clocked Sandie's in some benches on this board, I'll take those results over a questionable 5.2ghz overclock. Lord only knows how many errors you're spitting out at those speeds.

A 4.5ghz Ivy is *NOT* equal to a 4.8ghz Sandy in multi-threaded tasks. Its 30% slower video encoding. Clearly in apps that count it's no faster.

 

[BallaTheFeared]

I seem to remember that most people had a hard time reaching anything past 4.5GHz on most of the 2nd generation Intel® Core™ processors. So if I can get 4.5GHz at a lower voltage on these 3rd generation Intel Core processors and still get the better performance from the IPC improvement then I would say that it is most likely a good thing for most people (Ok not the few that can find one of those golden CPUs that you can work your magic on and get amazing results on).

This is the way I remember it too, 4.4-4.5Ghz was what people were getting around 1.35v

There very few that do 5Ghz with less than 1.4v, just because people like me dump 1.5+ into their chips for 5.3GHz doesn't take anything away from Ivy imo.

 

[MPiland]

In this article, they say it has really nice OCing potential: http://www.hardwarecanucks.com/foru...-intel-i7-3770k-ivy-bridge-cpu-review-23.html

And even in this one at the end when they list the pro's it says "nicely overclockable":
http://hothardware.com/Reviews/Intel-Core-i73770K-Ivy-Bridge-Processor-Review/?page=14

This is a smaller die, so of course the heat is going to rise since it has less area to dissipate in. And, I don't think Intel ever said that the OCing on this would blow SB out of the water, did they? I think people hyped it up too much on their own...

A 4.5ghz Ivy is *NOT* equal to a 4.8ghz Sandy in multi-threaded tasks. Its 30% slower video encoding. Clearly in apps that count it's no faster.

One of the reviews listed (not sure which it was) said IB ran better with 3DS Max and Maya which are multi-threaded

What the hell does crapdozer have to do with anything? Yeah I get your stupid passive aggressive comment pal maybe you should go to some other website that is about conspiracy theories, anyway, I expected a better overclock considering its a smaller node and an improved process, this has been consistently happening for the past 5 years and has come to an end.

The IPC increase is miniscule and there is no reason for me to upgrade my 2600k.

 

[LagunaX]

Bottom line it is not easy to find a low voltage 4.8ghz 2500k, 2600k, or 2700k.
They are the 10% of the Sandy Bridge pool, most fall in the 4.4-4.6ghz range.

However it seems like there is no problem at all getting to 4.5-4.6ghz on Ivy.

An Ivy will perform as a Sandy clocked 200-300mhz higher.

So unless you already have a 4.8ghz+ Sandy, the obvious choice is Ivy .

 

[DarkRogue]

This just seems to me like everyone running wild with unrealistic expectations.

Everyone seems to ignore the fact that physics is involved.
It's been stated several times that the die is smaller than SB while packing in more transistors. Of course it's going to get hotter, there's no way it can dissipate heat fast enough.

I for one am excited for IVB.
The power savings are very nice, and with a desktop CPU operating at 3.9 at 0.9v, this bodes very well for laptops and such with lower voltage CPU's.

I will OC my CPU of course, but it's not the only facet that matters.

 

[pelov]

This is probably the best IPC gains from any die-shrink 'tick'. Definitely solid. If anything was over-stated, it was the OC ceiling. This didn't come from Intel though, the official information released regarding IB appears to be pretty accurate.

Absolutely. The gains are great considering the HD4000 gains are fantastic and it performs incredibly well in the mobile segment under TDP constraints. But if you consider that enthusiasts are overclocking their chips anyway the IPC gains look like they're not enough to overcome that overstated OC ceiling. As an upgrade from an SB it makes little sense but for someone with an older CPU, or any AMD CPU, it makes far more sense if you couple it with the added Z77 features. Those who care about CPU performance also tend to be the same people who OC. For them the difference between SB and IB is negligible (outside of PCIE 3.0).

This thing is going to make a far bigger splash on laptops. The i7 IB chips that were reviewed are far too expensive for me to care as I don't need a quad core 8-threaded CPU on a laptop but I'm definitely looking forward to the i3 counterparts. HD4000 on an i3 looks like it may be very very good

seems to me If you have a Solid 4.4-4.6ghz setup that the Ivy doesnt provide enough of a "tick" to actually make the upgrade. Unless you want to say you have the latest and greatest...

 

[BallaTheFeared]

Dons IB i5 is right there with my 5.2GHz SB i5 and he isn't even pushing his chip.

BUT IT HAVE 3D TRANSISTORS !!!!!!!!!!!!!!

/sarcasm

 

[CPUarchitect]

Kyle at [H] was clever and did an IPC // OC review. Worth a read. The IPC is a bit lower than I was expecting...

How could you possibly have expected more? It has been known for quite a while that Ivy Bridge has the exact same micro-architecture as Sandy Bridge, except for handling some register moves at the register renaming stage (which is more likely to reduce power than increase IPC since it's very rare not to have one free execution port out of three).

Other than that the divider went from 128-bit to 256-bit, but that's only for AVX so it's not going to affect IPC in typical benchmarks. They also improved the prefetcher but again it only affects rare cases.

Heck, it's surprising that this 'tick' offers an improvement in IPC at all.

That said, I'm glad to see quad-core really becoming mainstream for the laptop market. This sets them apart from ultrabooks which will only have two cores.

 

[kjackson09]

How good is the graphics capability of this chip? I'm not a huge gamer, but I do have a 30" LCD running at high resolution and would like to play the occasional current PC game.

Many thanks.

 

[CPUarchitect]

One of the reviews listed (not sure which it was) said IB ran better with 3DS Max and Maya which are multi-threaded

That's probably because of the 256-bit divider.

But that's nothing compared to what Haswell will bring us. Twice the throughput for every SIMD instruction, and 8x parallel memory access!

 

[jacktesterson]

I'm not going against Ivy. I just already own SB (and have since launch) and see no reason to upgrade. I went from a 1045T @ 4.0 GHz (I had an unlocked 1045T, fluke somehow) to a 2500k for the crazy overclocks. That thrill just isn't here for me this time and $250 for a 10% bump isn't worth it to me this time around.

That being said, I've had 4 different 2500k systems, and only 1 of them failed to hit 4.5 without big voltage bumps. (I like to stay under 1.35). 3 of 4 have been able to get 4.5 or higher with less than 1.35v.

 

[dma0991]

Should be pretty funny watching all those water cooling lunatics get stuck at the same clock speeds air cooling provides.

I am happy with 4.5GHz as I didn't want a chip that would practically be dead in a matter of months and having high temps for the sake of higher speed is not my concern as the heat has to go somewhere and that somewhere is my room which will be a furnace and I am not comfortable with that. Unless you're willing to supply me with a dozen or so spare IB processors and an air conditioner, I'll just be happy with what I can get with it.

seems to me If you have a Solid 4.4-4.6ghz setup that the Ivy doesnt provide enough of a "tick" to actually make the upgrade. Unless you want to say you have the latest and greatest...

I don't think I ever tried to convince someone with SB to upgrade to IB before. I've always said to upgrade every other generation, not every generation.

 

[darkxshade]

The reviews are for 3770k. I'm curious though as far as price to performance, how the 3570k stacks up against the 2600k and 2500k.
