Sandy Bridge real benchmarks without legends

[WardC]

What about doing single-threaded tasks? (Most of your tasks are single-threaded and do not take advantage of all four cores...we Mac Pro owners know about this stuff)

So in that case, in most everyday tasks except for those taking advantage of multicore, the 2.8GHz i7 Arrandale would be faster than the Quad-Core Sandy Bridge 2630qm, which has a significantly lower clock-rate.

I am speaking about web browsing, rendering pages, doing basic things such as Photo editing or anything but video rendering, Logic, compression, or running multithreaded apps such as rendering and calculation applications that take advantage of multiple cores at once.

That's what the Turbo is for.

FFS people, quit spreading misinformation.

Errr, ok, so what is it now? Significantly faster?

And Clarksfield did not have an IGP so it would have required a discrete GPU 24/7. Battery life would take a huge hit because of that and more heat would be produced all the time too.

Also, in 2008 and 2009, we had 35W CPU and 9400M/9600M GT combo. 9400M, which is the chipset as well has TDP of 12W so without the discrete GPU, the maximum TDP is 47W (not including displays, HDs and stuff). Quad SB has TDP of 45W and then add 3.9W for chipset (HM65). The total will be 48.9W, only 1.9W more than what we have had in the past.

I think we all wish this might come true. The only problem I see with that is the 35W was still dissipated by one fan on only one side of the case. An additional 10W may be too much for the thinness of a 13/15" MBP and one fan.

The Anand article says it best, "TDP isn’t really a useful measurement of power requirements. All the TDP represents in this case is the maximum amount of power Sandy Bridge should draw. So worst-case battery life under full load might drop, but the real question is going to be what happens under typical workloads."

But they may go ahead and do it anyways and just have it downlock like in the first gen MBA. You never actually got to use the full CPU in the MBA because it would always downclock in half due to overheating quite quickly.
You can manually override this with Coolbook Controller if you don't mind the 100C heat and always have it on a cooling pad though.

This is the third time now that this link has been posted in this thread.

Are people ignoring it because it's in German? Here I'll throw the URL into google translate. Not that it needs to be translated anyway since numbers are numbers in any language.

People should probably stop talking about computer hardware if they don't even understand that the 32nm process isn't the only thing that matters in a processor's performance.

Ok and The contents in this link speak the truth beyond any doubt? So if what is being said is true, we can all trash the current arrandale mbp because sb is going to be leaps and bounds better in every way conceivable. Not only will it run significantly faster, but it will sip significantly less juice from the battery. It is nothing short of revolutionary. Actually a miracle would be a better term.

Basically yes. All current mbp are junk compared to what will come. All websites have shown incredible Reviews of sandy bridge and revolutionary is a good word to use.

.... Another day of waiting for the release of the new mbp.... What torture !!

I didn't say SB was leaps and bounds better did I? I didn't say people should trash their Arrendales. Sandy Bridge isn't making the Arrendale's any less powerful. A few uninformed people in this thread however are saying dual core SB processors offer no performance gains above Arrendale aside from IGP performance which is completely false. Is it really that hard to comprehend?

My bad. I was thinking of the desktop 2-core. I think the german article also said the mobile SB 2 core wasn't much faster in Cinebench, same as in the Ars interview. However that was only one app.

Overall, the SB 2 core is perhaps 10-20% faster than the previous generation core. I don't know about you, but for me, while it's good, that is almost undetectable in daily computing on my laptop. And yes I use VMs and Handbrake encoding. I'm more excited about longer battery life and doubled IGP graphics.

An hour extra on the battery would help me almost every day, and better IGP would mean less power used for graphics heavy apps, and better performance in games, or even being able / not able to run many Valve / Steam games. (however, games don't earn me money, work does.)

Not sure if better IGP would help with Youtube/ Flash / iPlayer from the dual viewpoints of running smoother or using less power but it might well have a better H.264 hw decoder which would make a difference in some of these areas.

Flash/youbtube etc. acceleration is only available on Nvidia graphics cards at the moment. If Apple were going to use the Intel IGP, they will need to open up the "Video decode acceleration framework" to support the Intel IGP.

HD3000 supports OpenCL and QuickSync is the hardware acceleration. Obviously that would be addressed with an OSX update since it's not on the Apple market yet.

I agree with what you are saying but better is a very vague word. What order of betterness are we talking about. If it is evolutionary like from santa rosa to penryn or penryn to arrandale, I guess that would make sense, but if it is revolutionary like the improvement in the IGP seems to be, combining the two will make it leaps and bounds better than anything that came before.
