AnandTech Ivy Bridge Performance Preview - Including iGPU Performance

Hi guys;

We've been working on a little something over the weekend that you might be interested in. On the CPU side Ivy Bridge is largely a tick - a die shrink for a reduction in power consumption and manufacturing costs - but on the GPU side things are far more interesting as I'm sure many of you are aware.

Cliff notes: It won't beat Llano, but it is upwards of 40% faster than HD3000 (SNB)
 
boo 😛, only confirms what we were all expecting, ie 5-15% faster with improvements to the GPU being the emphasis

right now I guess I really only care about how well Ivy can overclock and the rates we'll be able to hit, guess we'll just have to wait a little longer
 
That's a shame... I was expecting more from IVB. Perhaps drivers will improve by launch. Pleasantly surprised on the CPU side of things however.
 
I went to check out the OC section, but it didn't exist...

Edit: Also Quick Sync just got super stupid...

Pretty nice numbers for just a die shrink. Good to see buyers can get more performance for "free."
 
If a transcoding type app could make use of cpu/ and the internal igp at once, I'd imagine 400 fps type performance. The key is software. Might the AMD part not be performing well because of non-optimization ?

A gpu is still a general purpose processor, just optimized for parallel processing. Intel's QuickSync is dedicated video encoding hardware so it can be much faster and use less space and power. That said, it at best has limited reconfigurability, while a gpu could be programmed to do almost anything. (although most people's needs are much less than "almost anything")
 
Looks like the i7 3820 with its 3.6ghz stock speed is absolutely no match period for the i7 3770k at 3.5ghz.

Feel sorry for anyone who bought a uber expensive x79 motherboard and i7 3820 cause the lower tdp 3770k outperforms it in every way making it a bad purchase.

Not earth shattering performance but the fact it pulls less power then a i5 2400 makes it appealing.

From the chipset comparison charts,the z77 and the z68 look basically identical,besides different a different usb 3.0 config.
 
On the CPU side, amazing value. On the IGP side, it's an improvement but the overall situation is kinda funny-

3870k, for presumably about half the price, is superior for gaming if you are going to rely on IGP

And if you are going to buy a graphics card, you will likely spend more for an AMD GPU than you spent on the 3770, though admittedly a much larger portion of that money goes to the OEM rather than AMD.

Still, I find it a funny situation.

(Or you could pair the 3770 with an nvidia card, but until nvidia actually produces something that would just be silly)
 
Nice, right in line with what most were expecting. Nice drop in TDP along with a modest increase in power and a great jump in video power. The quicksync performance is really nice.
 
Quite disappointed in the GPU. Sometimes 50% faster, but often not even that. On the CPU I didn't expect more, but I did expect still lower power consumption. So all in all, I'm not impressed.
 
Awesome review as always and nice to get it this early. As others have said though, the most wanted information is overclock potential, at stock the chip is slower than a 4ghz Nehalem most likely. Need OC potential 😎
 
Intel is closing the gap on iGPU performance, but only on Llano. Trinity will reestablish AMDs lead on igpu performance. Then it will be the same argument again --- CPU performance or GPU performance.

Image quality is still very questionable. I am sure Intel has optimized for the Ansio bench to make it seem like they have improved their algorithms. Have they really? What is Intel doing on LOD bias?

In game quality is what I would be interested in seeing --- side by side.

Even current SNB quicksync performance is nice, but rendered mostly useless for the simple fact that I've not yet found any software that allows for 2-pass encoding using it? In fact, out of all the ones that I tried only Mediacoder had acceptable video/audio options, though it only uses quicksync for the encode portion. So yeah, I'm hoping that the 2-pass thing might just be a restriction of SNB that'll go away with IVB, otherwise it's pretty useless for high quality 1080p transcodes where size reduction is the main objective.
 
I will be in the market for a new laptop this year, and I will wait to see what Trinity can do before buying. However, I very much doubt that AMD is going to bring out something more compelling than Ivy.
 
Not sure why anybody cares about the IGP for a $330 performance desktop part. I think I will continue to use the high end socket variants of Intel chips out of principle -- don't want IGP junk sitting in my box.
