why is Iris 6100 slow on performance between 4000 HD graphic?

I had an older 2013 pro and compared it with this new 2015 pro both "13 inch"

they have the same performance how come 6100 not faster?

MacBook Pro with Retina display, Windows 10

While performance can be linked to a single application and how it was optimized to use the card a more common explanation might be because they both share system RAM which offers far slower performance vs a dedicated GPU from the same generation.

Apple only offered a single 2015 MacBook Pro with a dedicated GPU, and no MacBook or MacAirs come equipped with anything but an integrated card, by throttling the graphics processor options Apple was able to claim longer batter life, better cooling and better cost, but if you are looking for GPU performance out of a Mac portable you may consider other platforms as a far more viable and often better performing lineup at less cost.

Thanks for answering JimmyCMPIT.

I understand what you mean but even so I realized Apple has not update driver for the GPU as The Intel inc said.

I also looked at the performance in RAM on the 2015 pro and it dose not share RAM between Mac and Windows.

as we all know compare Windows 10 to Mac OS X EL Captian Windows takes the lead of performance.

but even so it's very slow as the 2013 pro.

so any reason to upgrade something for giving performance on 2015 Bootcamp? or the CPU/GPU

I'm not sure of there is differences using Windows on Mac and they both share the same "update" driver.

or Windows can easily update from Intel website and Mac can't cause of Apple them self have to deliver.
