Apple releases new aluminum iMacs

As everyone already knows, Apple nixed the 17" iMac but introduced new 20" and 24" models with a thin aluminum frame, and at the same time, they dropped the prices significantly. Some specific points:

- It can support up to 4 GB. The previous model could only utilize up to 3 GB, because of limitations with Intel's chipset.
- The screen is now glossy. If you plan on getting a new iMac, hopefully your light setup isn't glare prone.
- The graphics has been updated to the Radeon HD 2400 XT on the low end model, and the HD 2600 Pro on the two higher end models. While the 2600 Pro is an improvement over the previous Radeon X1600 and the GeForce 7300 GT, it may be inferior to the previous 7600 GT option in some real world usage, although we have yet to see Mac benchmarks with these two models. There is no option to configure a higher end GPU in the current iMacs.
- All models now have Firewire 800.
- The CPU is up to 2.8 GHz, utilizing Core 2 Extreme. This is a pleasant surprise.
- As expected the bus speed has been increased to 800 MHz. However, memory remains at 667 MHz, since SO-DIMMs are used.
- The wireless keyboard has no numeric keypad, and uses a keyboard design similar to the MacBooks.

Overall the new iMacs represent an incremental upgrade, with some curious changes such as the less than impressive top-of-the-line GPU, and loss of the numeric keypad in the wireless keyboard. The loss of the matte screen is also going to be annoying for some users, but I'd expect most people won't care, or will actually prefer the new glossy screen.

However, I'd recommend that most Core 2 Duo iMac owners stick with their current machines. Also, this may represent an excellent opportunity to pick up the previous white iMacs for cheap.

I'd like to go a little off topic & ask about a post from 2006... & not sure if the response to the old post would come up as a recent entry...

but its about Intel GMA 950 Accelerator & Core 2 Duos - so that should at least get me in the ballpark.

The post under discussion referenced the Mac minis & OpenGL performance.

One of your responders said they had used SolidWorks on a 2.0GHz Core 2 Duo. I take this to mean thatit was one of the plastic Powerbooks - basically the same innards as the new higher end Mac minis.

I was wondering if there's any new input with respect to machine performance using SolidWorks...
