Hi Guys,

I had an Ivy Bridge rMBP up until the 2013 MBA came out and then I sold it and got the Air with the intention of getting the Haswell rMBP. I have sold my Air now and ordered a new 2.3GHz, 16Gb, Iris Pro, 256Gb rMBP.

I am not a gamer and glad that Apple has given the choice to buy the rMBP without the dGPU. With the Ivy Bridge rMBP it did stutter under OSX every now and again.

Anyone with the Iris Pro only rMBP having any issues or is it nice and smooth now?

Cheers.

100% buttery smooth, from what I can tell so far.

The same cannot be said for the 13'' with iris 5100, there is noticeable stutter still... sad.

How is UI performance in scaled resolutions? (Scrolling, resizing, Mission Control, etc.)

on highest resolution - i don't notice any lag at all, for any of those functions. but it is noticeable on the 13'' at highest resolution (mainly mission control operations and desktop switching).

sorry your wrong.

not only does the hd4000 i have work great , so does the 5100....stop spreading misinformation.

No, you are wrong. The 13'' works great at default resolution (which is way too big). Try changing the resolution to its highest (so, most screen real-estate), then try swiping motions such as switching desktops.

You stop spreading false information. And the hd4000 works great? LOL, you must be blind or something.

Mavericks seems to be doing the serious improvements. I noticed in the new Mail app when you click "Show All", the column expands smoothly. Before it lagged and just felt cheap. It wasn't Apple.

The Iris Pro is nice but it performs similar to the high-end pro because it's pushing all those pixels on the retina display.

I believe this current 13-inch pro model is just a temporary unit until they can install that retina display on the Air, probably with the next gen CPUs with integrated high-graphic performance.
 
From my 2 hour test in store, the Iris Pro will give you buttery smooth experience in Mavericks. It's all about the 128MB embedded cache.

no they both work fine, i run both at 1920x1080


again....stop spreading misinformation, there is no lag.

until you own both....do not comment.
 
All of you are wrong. The stuttering was proven to be the CPU being maxed out. For whatever reason Apple has chosen not to offload certain UI aspects to the GPU yet. Whether its bc they are not powerful enough, or would use too much power is anyone's guess.
 
Oh joy.

"It lags for me."

"Nope, no lag"

"Yep, it lags for me"

I remember we were having this discussion about a year ago when the first Retina MBP came out and people were saying that the computers were lagging on the HD4000. Then some people disagreed. Then those people admitted that it became "smoother with X patch", which seems to say that it did lag.

I mean, yes, it sucks. But get over it, lag exists.
 
As said before, it was proven the lag wasn't due to the GPU but the CPU. The conversation is like asking if an electric car's engine burns fuel faster than a combustion one...

Ya, don't think thats true.

When I had my early 2013 15'' rMBP. There was terrible UI lag (i.e. - mission control, switching desktop, etc.) when I had HD4000 graphics enabled (via gfxcardstatus), and the lag immediately went away when I enabled the GT 650M.

What say you?

I second this.

Iris Pro is pretty much as fast as a 650M so OP will have no worries.

Mavericks also has bought some lovely improvements.

TDP can probably explain that behavior.

I'll also leave you a quote from Anand's article, although you're obviously still entitled to ignore what a reviewer lie him has to say.

There's not much you can do here other than wait for faster hardware or buy the fastest CPU available on whatever system you're considering. Single threaded performance will scale linearly with CPU clock speed, so higher clocked CPUs should deliver smoother scrolling performance. Ultimately just scaling CPU clock is an inefficient way to solve the current UI frame rate issues. Future revisions of OS X will likely shift even more UI workload to the GPU, plus we'll see new microprocessor architectures that will perform better with these types of workloads as well. The only issue is I don't know when either of these things will happen. Haswell should bring a good increase in IPC and maybe even a slight increase in frequency, which will definitely help.
