Core i7-3770K "Ivy Bridge" Offers Solid Performance and Efficiency
Earlier today, Anandtech posted its preview of the Core i7-3770K "Ivy Bridge" processor. The i7-3770K will be the fastest Ivy Bridge LGA1155 processor, when launched. Anandtech put the chip through a battery of tests, starting from overall system performance synthetic test suites, such as SysMark 2012, content-creation, video transcoding, gaming, and system power consumption. The one conclusion you can draw out of these tests is that the Ivy Bridge kicks butt. It has higher performance per core, and single-threaded performance than even the Sandy Bridge-E (LGA2011) chips, it aces content-creation, shines with gaming, and has power-draw lower than even the Core i5-2400 from the previous generation. If you've been holding out over a platform upgrade for a while, the Core i7-3770K is rewarding. But then there's no big incentive, if you're coming from Sandy Bridge LGA1155 chips such as the Core i7-2600K. Read the full review at the source.

This is an Intel thread! Ivy bridge is so much faster and has so much more performance per core than Nodozer that it looks to like it is going to take an entire remake of the architecture and another generation just for AMD to actually catch up!
I am a fanboy of innovation and I think you fail to take that into account when you FLAME on me for pointing some thing out that I see! What now, I am not entitled to an opinion because of you?
I swear You must have some kind of program that goes off any time I say some thing about Bulldozer or AMD or you just like to troll every post I make. You really need to get off my back.
It's clear calling Bulldozer Nodozer will piss people off, so expect to be flamed for it.
And it's clear talking about Bulldozer negatively in EVERY SINGLE thread without adding anything constructive to the debate will piss people off, so again expect to be flamed.
As far as performance improvement, the amount of improvement is fairly minor, it's power consumption that got a large boost for loaded workloads. Idle power consumption hasn't improved a whole lot.
As far as improvement over the 3820 and the 2600k, it's pretty minor in most cases with an average of what? 5%? It's a revision of the same architecture so you're not going to see a lot of performance benefits on IVB over SB as far as IPC in concerned. Now we will have to wait to see how it over-clocks, because lower loaded consumption will benefit over-clocks if voltage vs temperature scales equally as well.
Then again it might not, because smaller circuitry will increase resistance, even more so as temperature increases.
Edit: For those who haven't learned how resistance and circuit heating works, I recommend reading a little bit about Ohm's law and Ohmic Heating... but for those who are too lazy to learn some Physics, basically as resistance stays the same (which it doesn't resistance goes up with temperature,) voltage increases will exponentially increase the amount of heat generated. With that said a 32nm wire has less resistance than a 22nm wire. So the same voltage on different sized wires will result in a higher temperature on the 22nm chip. This is only true if the 22nm aren't as long as the 32nm counter-part, so we won't really know until we can test it but theoretically with a similarly size die, temperature at the same voltage will increase. :)
All in all, IVB 3770k looks like it is going to be a nice chip, but it's not worth an upgrade over a 2600k and a couple bins up on turbo will close that gap very quickly. Keep in mind clock-for-clock, IVB will be almost the same as SB.
What every single post? I have NOT! Bulldozer is a fine CPU, I was talking about the CHART and the numbers do not LIE! Ivy bridge and many other Intel chips are going to be higher in price, YOU GET WHAT YOU PAY FOR! Want lightning fast performance? Then you will have to pay for the better product.
Thing that makes me angry about it is that AMD has taken a step backwards! They have caused a mess for every one! Look if Intel keeps on this path AMD is out! And that is NOT going to be good at all! Right now the price of Intel's offering is way too high as it is, If AMD could match this it would lower prices across the field! With Ivy bridge it looks like it is going to take more than AMD is willing to do! :shadedshu
Do you ever see me referring to Intel negatively? No!
Do you ever see me calling Intel an unassigned and unofficial name? No.
So, apparently me being respectful towards Intel and their very high quality product makes me a fan boy? - You are not very smart, one would presume. What has this got to do with anything? Did you even comprehend my original post?
I never said the chart lied. I never said you didn't get what you paid for. I never brought up number or prices at all or performance comparisons.
All I said, paraphrasing. "trickson why do you always talk about AMD negatively in every thread". Where did you get performance and prices from????
It's amazing, how can you respond when you don't even understand or comprehend the topic matter of what you are responding to lol
Edit: That includes you too Dent1, I'm not singling trickson out. We don't need a flame war, but I appreciate both of you not pushing this further. :)
Edit: IVB will benefit low-power platforms more than anything else.
Dent1 stop derailing and fanboying please. :wtf: :roll: :toast:
Anyways, can the internal GPU be totally disabled?? I mean completely shut down when running with a dedicated PCI-EX video card??

en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity which explains why resistance goes up as wires get smaller (current density increases because the wires are smaller.)
and en.wikipedia.org/wiki/Joule_heating which explains why it gets hotter with higher resistances.
Also as temperature increases, so does resistance, so generally speaking a 22nm has more heat issues at higher power levels. Tri-gate transistors are a good idea but it doesn't make the wires any less resistant to an EMF, actually it is the exact opposite.
Edit: I feel like I've explained this 4 times in the last week. :mad:
Now back to ivy bridge. I am hoping ot get one of these 3770k and a Z77 motherboard, because I heard that IB may not work on P67.
Trickson, brought up performance of Phenom II based on Anandtech, so perhaps your post should have been directed at him? Yes/No
Sanadanosa, was agreeing with Tricksons analysis of Anandtech's Phenom II performance, so perhaps your "Read more then one review" jibe should have been directed at him? Yes/No.
You either will ignore my response or pretend you didnt read it as a lame excuse not to apologise. Sigh.
