I'll be waiting for joe average data and all the rest to support all of your wild, broad sweeping statements.

As long as they come from broad, sweeping experiences, don't let them stop you from extrapolating an extremely narrow set of circumstances into general requirement.

We'll be standing aside, talking amongst ourselves.

Also, since you haven't answered my question, let me reiterate:

Or the ones that prove that graphics cards have little to no effect on everyday tasks? Those are more a question of technological background, and that has been amply explained.

Which data are you still missing?

You're the one making wild, broad sweeping statements and accusing others of trolling. You ignore the proof we offer you. You're getting obnoxious here, freudling.

I think we are going to have to admit that further debating is futile. Some people just don't know how to admit defeat. Or perhaps this thread now belongs in the PWL.
I have plenty of more important things to do, if only I could bring myself to do them....

Let's just consider this issue closed and continue with the thread. I don't think there is a point to discuss it any further.
I don't suffer from insanity, I enjoy every minute of it.

The result: either faster at the same power consumption or the same speed but much less power draw and heat production. It's not just a tick, it's a tock.

I know about the manufacturing process, but all that means for Ivy Bridge is slightly higher clocks and/or lower voltages. The CPU core is not especially changed, and the rumors make it look like a Penryn thing for the CPU. Intel calls it a "tick +". Since the Intel Switch, there have been a few big boosts: Nehalem for the MP, Lynnfield for the iMac, and Sandy Bridge for the laptops. I don't see Ivy Bridge being anything near that large.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

Hi. In regards to the spec bump, I was curious if the new MBP was able to take advantage of higher spec RAM in any meaningful way. I know the advertised spec, but I'm looking on Amazon and can get either spec matched memory (Samsung MV-3T4G4 4GB DDR3 Laptop SDRAM (1333MHz PC3-10600)) or actually a higher spec (30nm SODIMM 8 Dual Channel Kit DDR3 1600 (PC3 12800) 204-Pin DDR3 SO-DIMM MV-3T4G3D/US) for about the same price.

So... I was wondering is there any conceivable benefit to the higher spec, such as lower operating temperature due to 30nm instead of 40nm or perhaps longer battery life because of lower power consumption (1.75W vs 1.89W)? I know the memory can't perform faster, but are there any other benefits to consider?

No idea.

The default shared VRAM is 384MB in the 2011 13" MBP; if you upgrade the RAM to 8GB VRAM is automatically increased to 512MB. I don't know if the VRAM increases if you upgrade to 6GB.

You will not see any battery life improvement. Sandy Bridge will supply all RAM with the base 1.5V, which means that power consumption is the same. Ivy Bridge supposedly adds a low-voltage mode for RAM, at 1.35V, which would save some power with supporting RAM.

Quadcore mobile Sandy Bridges support DDR3-1600, but the practical benefit is zero. You'd need all four cores work flat out (with streaming data so the L3 cache gives no benefit) for that to even have an effect.

My comment was in reference to the entry 15" MacBook Pro. It's discrete GPU went from 256 MB to 512 MB.
