Yeah, I just realized that. For a second I thought it’s a pure CPU benchmark but that wouldn’t make any sense at all looking at the scores and CPUs.

If those MBAs were plugged in, then they were probably turboing at an operating frequency much closer to the i7 in the MBP on the right. Also, the 2.67 GHz first-gen Core i7 mobile CPU has lower performance per clock and is a dual-core chip with a less-awesome Turbo Boost function and lower performance per clock.

16, 8 per side of the SoDIMM.

What are the MacOS memory management policies, anyway? Windows does a lot of ahead-of-need allocation and caching from disk, which means that more RAM is always a benefit even if marginally. Does MacOS do anything similar?

Hmm. So what'd be a good alternative to a Mac Pro, if we're never gonna see another? Building a Hackintosh seems like more than I want to do, but I'd like to have a robust machine for my own development work.

If Apple drops the Pro, it looks like the options might be fairly bare:

1) Just get an iMac. If the workload demands and allows, use a render farm for heavy lifting. Definitely doesn't work for everyone.

2) Hackintosh, but compatibility might be spotty or even lovely if there's no official Patsburg/SNB-E support. Obviously subpar.

3) Transition to Windows or Linux workstations from Dell, Lenovo, some other vendor, or even whitebox workstations. Obviously kinda sucks if you've got a platform investment in OSX of any kind.

But I think the writing has been on the wall for a while that Apple has been focusing on consumer hardware/software/services and finding a lot of money in it. The Apple ecosystem really works best as a consumer money siphon. A workstation doesn't print cash the way an iOS device does. Even if the workstations are profitable, it may just be more profitable to focus on other things.

What about high end iMacs? They might not match what a super duper new Mac Pro would do, but I'm pretty sure the 8-core ones etc would be competitive, and I don't think the high end ones are still mobile chipsets.

As someone who owns a (few years old, but was upper-mid range model at the time) Mac Pro, they've never aggressively had the TOP END video cards really. I even upgraded to one of the later ones -w hich was lagging behind Windows equivalents (price:performance).

I'm not a video professional though!

The high end iMacs aren't 8-core, they're 4-core with hyperthreading. Mac Pros are 12-core with hyperthreading, a full 24 logical processors. A top-end SNB-E update would be 16-core with hyperthreading, 32 logical processors. That's four times the CPU of an iMac. Hell of a difference.

I just wish Apple would go back to discrete-only GPUs. And maybe giving us nVidia or ATI chips again? Can't understand why they jigger the entire system into offloading all graphics work including the GUI to the GPU (brilliant) and then start using GPUs from a company that hasn't figured how to make good ones yet (retarded).

You'd prefer ATI over AMD? AMD bought ATI in 2006.

As for why Apple would use both the Intel IGP and a discrete chip, the answer is really, really simple: better battery life without sacrificing the option of more horsepower.

What refresh rate are you working with, 60 Hz? If it's much higher than that, you might be up against the adapter's signal limits; in that case, dropping the refresh rate should open up higher resolutions.

Er... I just Googled around a bit, and this seems to be a moderately common issue. Some folks have reported that Apple support told them it's not something they were going to fix, either, given the outdatedness of VGA.

One more question - I have a 2 Ghz Intel Core 2 Duo iMac that I bought new five years ago now I think. Is it possible to replace this thing's 250 GB hard drive with something larger? If so, what do you recommend, brand-wise and model?

It is, it just takes a standard 2.5" laptop drive. A Western Digital Scorpio Black would be a good choice, and you can get a 320GB, 500GB, or 750GB drive. If you want to go balls-to-the-wall on speed, get a Seagate Momentus XT 750GB drive - it includes some SSD caching on the drive that works automatically.

Wow, ok, big difference. So why haven't other manufacturers of displays and laptops moved en mass to MDP, especially when Apple made the spec widely available? It's been out for years at this point.

There's more consumer call for HDMI and DVI, and mDP has only been a part of the official DP spec since DP 1.2, which is only supported by the Radeon 6000 and 7000 series and GeForce 600 series (most of which use mDP liberally). Additionally, for the few models with full-size DP ports, why not wait for Thunderbolt to re-engineer them? DP models are fairly high-end anyway, so they're good candidates for TB, so why spend engineering resources to sell something only for a few months between mDP becoming official and TB replacing it?

It was patched for LAA/PAE at 1.3.10 and so can use 4GB all by itself, actually. 2GB is the maximum for 32-bit software without LAA/PAE (almost all games and 32-bit software), and 4GB is the limit for 32-bit software with LAA/PAE support (Skyrim, 32-bit Adobe software, maybe a few other things).

Get a GeForce 670 instead. A 580 would have to pretty much be the one and only expansion card in order not to overtax the power supply. A 670 is faster and quieter and priced similarly anyway.

The system is rendering 9.2 megapixels at 60 frames per second and then scaling that to 2880x1800. That's an incredible amount of work, more single-screen work than any current-gen GPU is designed for (never mind the fact that it has to run on Intel HD 4000), and far more than a piddling 3 megapixel, non-scaled iPad. And without machines like the MBPR, there never would be a GPU designed for resolutions like that until 4K cinema started hitting consumer price points in, oh, 2021.

For a bit more detail, you don't even have to drain it all at once. 100% worth of draining per month is fine, even if it's 10% per day across ten days.

Actually, not draining the battery fully each charge cycle is a bit less wear than spreading it out is, even.

Rumors have it that Apple will be launching a 13in Retina Macbook Pro sometime in the Fall. They say it will have integrated graphics. Can someone who understands these things a little better than I do shed some light on how well an integrated graphics chip will be able to push so many pixels? Tech blogs seem to indicate the HD4000 is a big jump over the HD3000, so maybe games would be possible? I really only play Civ5. I just think the 15in is too big for me.

I had a Mac Mini running an HD3000 integrated graphics chip and was able to do two 1900x1200 monitors (4.56m pixels) under normal conditions easily, though games were a no-go. A retina 13in screen, if they use the Air's 13in resolution of 1440x900 but make it retina, would have 5.18m pixels. Without any technical knowledge of how these integrated GPUs work, it seems like the difference of .5m pixels shouldn't be too big of a deal. Someone with some technical knowledge please shed some light~

GPU performance scaling doesn't directly line up with the number of pixels rendered for all workloads. For just rendering a desktop, you'd have to go way over 5 megapixels to have any performance issues. People (even ITT, I think) have run an MBPR with two Thunderbolt displays (~12.5 megapixels) with no change in user experience.

Where the MBPR is somewhat infamously cocking up is that the scaling options for non-native resolution involve an Apple-custom scaling algorithm that runs on the CPU. Native GPU-based scaling wasn't high enough quality for them, and for whatever reason they didn't implement the custom scaling as a GPGPU program.

Gaming is another story. Game scenes are much more difficult to render than a desktop, because you have a lot more going on that requires processing. Long story short, with modern games, HD 4000 is indeed a huge upgrade from HD 3000, but it's still a low-end, low-resolution, low-detail gaming GPU. It's just too limited in execution resources and memory bandwidth to shuffle around a modern video game's large amounts of textures and geometry. Even the GeForce 650M is decidedly midrange. On a 1920x screen, Thunderbolt display, or Retina screen, you will always have to pick a smaller-than-native resolution and/or lower details to rock bottom in order to play with acceptable framerates.

According to anandtech's review, Apple's custom scalers run on the GPU (http://www.anandtech.com/show/6023/...isplay-review/7). Typically, resolution scaling happens in fixed-function hardware, so even a custom GPU implementation is slower than the default scaling.

The MBPr also has an IPS panel, which is nice if you're dealing with stuff that needs decent color-correctness and contrast ratios (which is assumed for designers) and you don't have an external monitor.

Quick correction: the 1680x1050 high-res 15" display has a better color gamut (full sRGB plus a bit, vs. a bit under sRGB) and slightly better calibrated delta-E (though MBPR is still better-than-the-eye-can-see good). The MBPR's contrast is indeed better, though.

Why did some older Mac video cards come with the ADC connector? Was it for USB data and video only? Surely they didn't actually pipe power through the video card to power the display did they?

They sure did, 100W of it. The cards had an extra batch of pins near the slot hole for additional power. The only reason Apple stopped was that the 30" Cinema Display needed more than 100W.
