Early Ivy Bridge Sample Tested

[SoF]

It's a bit like when Core 2 was shrank from 65nm to 45nm, nothing big but still a little architecture optimization.

65nm to 45nm was E6850 vs. E8600 - that was a boost in performance and raw MHZ oc...I am not sure yet if we'll see such big improvements.

As usual from die-shrink "tock" at this point u can add the typical 4 ~ 10% IPC increase (around 15% in some special cases) but what is attractive is its performance/power consumption/overclocking. I pray it'll do like 5.5GHz @ 1.35v on an average sample and consume quite a bit less power than Sandy would do at like 5GHz 1.4v. This is just speculation but one can always hope right.
I like throwing my overclock speculation pre-launch so here's mine:
Worst sample: 5.3GHz @ ~1.35v
Average sample: 5.5GHz @ ~1.35v
Best sample: 5.7GHz @ 1.36~1.37v
i5-3750K / i7-3770K on good aircooling

If there will be numbers like that and it scales with cold --> big win...but I am not sure yet if it will really be that good...

Yea 17% sounds a little optimistic (and the first test probably is using AVX) but when isn't a score produced by the manufacturer itself always a bit higher than what average joe gets in the same test? I bet we are more likely to see maybe around 10% or so in those tests. But OMG @ the internal GPU performance increase... sounds like it might be able to play a few even newer games at lower res quite fine.

There is a lot room for better bios and mem-tweaking for sure - thus initial results are not reflecting real world performance at this point imo

2600 runs at 3.4/3.8ghz while i7 3770 will be 3.4/3.8ghz, same default clocks
maybe the i7 3770 has an extra bin (+100mhz) with all cores active, but they're pretty close

i7 3770 will have a max turbo of 3.9 ghz.

More from Coolaler. Summary:

HD2500 15.26.0.2500

Vantage Total/GPU: 1487/1150 (900 Mhz)
Vantage Total/GPU: 2557/2022 (1500 Mhz)
3DM11 Total/GPU: P351/263 (??? MHz)
Angle-independent AF confirmed












How does this compare to existing SB and Llano graphics?

[Kallenator]

Looks slower :S
Maybe the drivers aren't up scratch yet?

3DMark Vantage
3DMark Vantage P GPU
IGP - Core i5 660/661 499 380
IGP - Core i5 2500K 1685 1295

EDIT!
Wait a minute, it says "HD2500", I think this is a nerfed HD3000. Which should explain the tad lower performance.

http://www.theinquirer.net/inquirer/...roadmap-leaked

All of Intel's Ivy Bridge chips will feature graphics cores, with the firm opting to stick its Intel HD 2500 in most of the chips. Intel will put its new HD 4000 graphics core in the Ivy Bridge Core i5-3570K and all of its upcoming Ivy Bridge Core i7 chips. Both of Intel's GPU cores support Microsoft's DirectX 11 and OpenCL 1.1.

[Hornet331]

Yep 2500 is the cut down version, the best version which also all mobiles chips get is the HD4000.

its has the same amount of EU as the HD2000 so its not a bad performance increase.

[STaRGaZeR]

So with early drivers it's more or less the same as the HD3000. Not bad for the cut down version.

Relatively speaking it looks like the improvement touted in the leaked Intel slides is true. I think it is also interesting to see the texture filtering quality.

Here is HD3000:

Huge improvement there (compare with the screen capture from coolare above)

This is what competitive pressure brings to the game. Intel needs to really ramp up their efforts on the graphics side or AMD will leverage that advantage to the hilt.

New Ivy ES leak surfaces: http://www.chiphell.com/thread-325516-1-1.html

This time some nice overclocking hints but no screenshot proofs for now though, but seems like he's saying if the google translated chinese is accurate he's saying 5GHz will be the norm and that he seems to have been able to boot (probably not stable) at 5GHz 1.17v on U12P + ordinary Delta 12CM fan! :o Excellent news if true, who said my predictions of 5.5GHz 1.35v was on the optimistic side?

Now I just pray that there won't be too much of a random stable CPU multi limit issue that hinders the overclocking significantly before power leakage/temp becomes the issue cuz if it does 5GHz at like 1.2v then there's obviously quite some headroom to go still.

If I'm not mistaken already Ivy Bridge will have some "dividers" which will improve the overclockability slightly or was that for the following generation?

Interesting. Even with immature drivers HD4000 scored very close to A8-3850 in 3DMark06 graphics tests. The gap between Intel and AMD IGP continues to shrink (considering that Trinity graphics will be only 30% faster then current apu).

Considering Intel iGPUs are working good in 3d marks only in previous generations......

It's not true. According to reviews I've seen, perf. gap in 3d marks pretty much reflects the overall perf. gap in real games.

Not really 3dmark06 is really CPU limited.

http://www.hardwarecanucks.com/forum...review-19.html

Notice that the 2600K scores 300 more points in the HDR-SM3.0 test even through they both have exactly the same IGP.

Not the same. 2600K has 22% higher IGP clock (1.35GHz vs 1.1GHz in 2500K).
But here is a good summery:
http://www.hardwarecanucks.com/forum...esktop-24.html
The gap in real games sometimes larger, sometimes less. But on average it is in line with 3DMark06 score.

[mrcmtl]

Ivy Bridge's IGP is really going head to head with Trinity's IGP. The GPU performance gap might still be the same. Let's hope AMD can close in with the CPU performance gap.

IB@22nm, not SBe.

IBe is SBe@22nm

The thing rumor is that there is no cold bug with IB.

how did they get rid of that with just die shrink?

EDIT: oh.. it's not entirely just a die shrink lol

[FlanK3r]

where are others leaks?

Prices of Ivy Bridge desktop CPUs - CPUWorld

[STaRGaZeR]

One 3570K please

[RPGWiZaRD]

One 3570K please

Yea I'd definitely get 3570K if upgrading to Ivy, I've barely had much use of hyperthreading on i7-860 and kept it disabled most of the time, might as well save $100. 2MB cache difference shouldn't have that much difference. Good to see the pricing will probably stay the same as last round (not too unexpected) as I think they are very good at those pricing levels. As long as mobo prices also stays roughly similar, a couple $10 might be slapped on in form of USB3 support though.

[repman]

Anyone knows if IB's IGP will support 10-bit displays? SB doesn't support it and all laptops that have 10-bit IPS screens can't take advantage of NVIDIA Optimus...

Ivy Bridge brings even better overclocking - Fudzilla

Initial reports from the Far East indicate that Ivy Bridge parts will offer even better overclocking performance than their predecessors.

Ivy Bridge brings even better overclocking - Fudzilla

I trust a random person on chiphell's forums more than what this guy has to write. haha Unfortunately that forums went private (needs a referer to even be able to join, believe me I tried!) shortly after the Ivy Bridge thread popped up, I wonder why haha, maybe they are all drooling over some OC results. :s It was said to boot at 5GHz at 1.17v but would be nice with some proof!

[kiwi]

Will it still be the case that only K cpus will be overclockable with unlocked multis?

[Mech0z]

Any news on when mobile chips should pop up? Might want to upgrade if I can do it cheap :o
