Phoronix: Preliminary Tests Of Intel Sandy Bridge & Ivy Bridge vs. Broadwell

Chances are if you have a Haswell ultrabook/laptop, you're probably not looking at upgrading to a new Broadwell design unless your Haswell laptop had hardware issues, you really need a longer battery life via more power efficient hardware, or you just fall in love with one of the new Broadwell devices. If you're running an Ivy Bridge or Sandy Bridge laptop on the other hand, it might be time for an upgrade to get faster Intel graphics and greater power efficiency. Here's some preliminary figures I have for showing off the new Lenovo ThinkPad X1 Carbon Core i7 5600U compared to some older SNB and IVB laptops.

32 vs 22 vs 14 nm lithography compared

But what happens with this kernel compile time benchmark? i somehow expect those i7 are much faster for the task

[Staffan]

Nah

I think I'll keep my Ivy Bridge ultrabook for another year.

Same here. Broadwell is noticeably better even considering the similar specs, but I wouldn't say it is good enough to warrant an upgrade. Intel systems aren't cheap.

Could we have a comparison of HD4400/4600 vs HD5500? Just curious.

No, I don't have any mobile systems with HD 4400 or HD 4600 graphics.

Hello. I have another question. How well this laptop plays H.264 and VP9 in Full HD @ 60 frames per second? Yes, I know VP9 is not accelerated so it uses CPU, but is this possible to playback this on CPU? On mine Sandy Bridge Pentium I don't have this possibility. On the other hand H.264@60 fps plays but consumes a lot of CPU, so it is not usable for watching when power is not connected to laptop .
Example:
VP9@60fps

I watch movies in vlc, you could use another media player of course.

If you turn it into an automated test profile I can try it out. Here's a video playback one as an example: http://openbenchmarking.org/innhold/...b2c3180c51c4a6

fair enough.

[duby229]

fair enough.

Of course if you have one, it would be pretty simple to run pts using the same tests to compare. That's generally what I do. Micheals hardware preferences are different than mine, so I usually just ignore his bench results and run his benches on my hardware so I know how my hardware performs

Also it's highly likely that openbenchmarking.com already has bench results listed for that hardware. That site is a pain to navigate, but there are tons of hardware configurations already benchmarked there.
