Ivy Bridge Preview on Anandtech.

Edit!!

Different load tests.

End edit.



Power consumption is no better than a standard Core i5!! :(

BTW,it looks like Anandtech has got a really crap Core i7 2600K example:

http://www.anandtech.com/show/4083/...core-i7-2600k-i5-2500k-core-i3-2100-tested/21

In their previous reviews the Core i5 2500K and Core i7 2600K had the same power consumption. Why no Core i7 2700K too??

I am an SFF PC fan,so this is why these sorts of things interest me(should be of no concern to full sized PC fans). I had a chance to pick up an SB Core i5 or Core i7 cheap and did not do so since IB had a massive TDP reduction,ie, from 95W to 77W(and a hopefully a decent power consumption reduction too). Seems SB is around the same anyway.

I was expecting the 22NM finfets to be massively better.

The HD4000 IGP is no doubt better,but is it any better than the HD6530D found in the budget A6-3500 though? Since most Intel IB CPUs will have an HD2500 IGP,it does not bode well. Maybe for laptops it will be more important though.

I thought this was meant to be a tick+ but it just looks like another tick.

Calm down it's only preview, you should be grateful for what you get as were not meant to know anything about Ivy Bridge until it's launched.

Actually,I had another thought - it is possible the power consumption figures in the Anandtech Core i7 2600K launch article might have been off. Disaster(for me) possibly averted.

I don't know what you were really expecting??

At idle it's a tad lower than SB, which is expected.

At load it's ~16W lower, as is expected (18W difference in TDP)

The TDP for the 2600K and the 2700K are the same, hence basically they draw the same power at idle and load, give or take.

All seems ok to me.

Look at the articles. The Anandtech launch article and the preview. Look at the relative positions of the Core i5 2500K and Core i7 2600K. Both the Core i5 2500K and Core i7 2600K are 95W TDP CPUs.

One of those figures is way off and I am hoping it is the SB launch article.

I am going to wait until the reviews are out to make a final judgement, as there will be more data available from other review websites too.

The article describes this as System power not just the CPU. I'm reading this as the power the whole PC is pulling not just the CPU
I know my 2600K only pulls about 110w at 4.8GHz and by comparison about 90w at stock - thats without using the IGP though.
 
Bring on Haswell... This is nothing more than a SB with 5-10% more CPU performance and a slightly lower power use. We are enthusiasts here so 5-10% and lower power use is not what we want to hear or really care about generally. We want performance.. It's a great CPU just as the SB chips and really aimed at people that have not gone SB yet and this may make them make the jump or again may make them think time to wait for Haswell.

Everything said in that article has been known since they mentioned Ivy really and non of it comes as a surprise to anyone intouch with CPU development and Intel's tick - tock approach. Great CPU and nice to see the 22nm process works at keeping power down, we also have to remember the new GPU in Ivy is more power hungry and larger than the SB GPU so overall a good die shrink and the added benefit of a better intergrated GPU for people who use that. Nice update for laptops and general purpose desktops that use the intergrated GPU but nothing special for enthusiasts and enthusiasts have better performance with their overclocked SB chips and who knows how well Ivy clocks yet the die shrink may make the CPU very delicate and hard to overclock in a safe manner. Can't wait for some reviews and ones showing how well the new process can overclock.

Thanks for the link :). Was a nice lunch time read but it should have been compared to 2700k not a 2600k as the top 1155 socket CPU. The 2700k uses a little more power than a 2600k and is a bit faster at stock than a 2600k too. The real gains for performance for Ivy vs a 2700k would be a touch smaller on performance but ivy will be better on power use and will show better power gains than a 2600k. Does not really matter too much a 2700k (3.5GHz) is a 2600k(3.4GHz) with a 100MHz speed advantage.

Cant wait to see the results of 3.0 with an Ivybridge processor just to see if there will actually be any performance boost?
 
I just checked the FX8150 review and the new "updated" Core i7 power draw numbers seem to be there. However,Anandtech bench(which loads of people use) has not been updated:

http://www.anandtech.com/bench/Product/288?vs=287

Regarding the power consumption differences I think I have cracked it. I just checked the bench results and it says first pass video encoding results which are lightly threaded ,which Anandtech did not state at the time of the launch review. The same benchmark is used according to bench.

The newer reviews use exactly the same benchmark but with second pass results which are highly multi threaded.

Balance restored to the force!!:p

That looks suspiciously like HT on/off there to me.

My Mac Pro draws an additional 15-20W when HT is enabled, compared to when it is off.

Hence the difference.

Just because the 2500K is a 95W TDP CPU does not mean it draws it ;)


Looks right to me tbh, when the 2500K replacement is reviewed (i.e. one without HT) you'll see it fit in below the 2500K.


Ivy Bridge *is* an improvement over SB in terms of Performance-Per-Watt, which if your running a SFF is exactly what you need. :)
