Apple iMac 27-inch (July 2010) review: Apple iMac 27-inch (July 2010)

While others have tried and failed, the iMac is still king of the hill when it comes to all-in-ones. All that's left to ask for is faster external storage and better SSDs, but for now it still comes highly recommended.

Craig was sucked into the endless vortex of tech at an early age, only to be spat back out babbling things like "phase-locked-loop crystal oscillators!". Mostly this receives a pat on the head from the listener, followed closely by a question about what laptop they should buy.

While the iMac got a big upgrade last year to Core i, and the 24-inch expanded to 27, this year's upgrade is a lot more modest. Processors have been given a boost in speed in Core i3, i5 and i7 flavours, and there's now a Radeon HD 5000 series inside and a second drive bay for a solid-state drive (SSD) should you choose to upgrade.

9.0

Apple iMac 27-inch (July 2010)

The Good

Huge, quality screen and high resolution. SDXC card support. Grunty new GPU. Still the best value all-in-one.

The Bad

No eSATA port. Gloss screen may irritate some.

The Bottom Line

While others have tried and failed, the iMac is still king of the hill when it comes to all-in-ones. All that's left to ask for is faster external storage and better SSDs, but for now it still comes highly recommended.

Don't think the option is there for later upgrading though — if you don't select the SSD option, you won't get the extra mounting bracket. While Apple wouldn't tell us exactly what brand of SSD would be supplied, we suspect it's still using Samsung, an inferior option for performance compared to the likes of the SandForce controllers out there today.

I'll have more of the same, thanks, waiter

The 27-inch iMac is otherwise the same dominating presence it was last year, with its gorgeous LED backlit, IPS-based 2560x1440 screen, aluminium styling and the included wireless keyboard and magic mouse (although Apple is, of course, pushing the Magic Trackpad as the perfect accessory — whether it is or not we'll leave up to you). Almost everything we said in the last review still holds true, from the gloss screen being a potential annoyance, to the bi-directional mini-DisplayPort connection and SD card reader being big positives. A nice addition this year is the ability to read large capacity SDXC cards, allowing up to 64GB of storage.

All your favourite ports are here. Well, except eSATA, but we imagine a certain devil would be skating to work on the day that happens. The SDXC card reader is on the side of the iMac, under the DVD drive. (Credit: Apple)

Benchmarks

While Core i7 versions of the last generation 27-inch iMac were available, we only saw the Core 2 Duo version for review, meaning our benchmarking this time will show quite the increase in performance, with the quad-core Core i5 processor pushing it higher.

Our review sample included a quad-core Core i5 2.8GHz processor, 4GB RAM, 1TB hard drive and a Radeon HD 5750 GPU, and sells for AU$2599. The base level iMac starts at AU$1599; however, this comes with a dual-core Core i3 3.2GHz processor, a 500GB hard drive and a Radeon HD 4670 GPU.

While iTunes shows a marginal benefit of seven seconds, in every other category the quad-core processor delivers huge increases in performance, particularly in the multimedia and the highly multithreaded Cinebench tests.

Conclusion

While others have tried and failed, the iMac is still king of the hill when it comes to all-in-ones. With Core i processors inside and Radeon 5000 series graphics, it makes a more than halfway competent production machine, the resolution alone making it nigh on perfect for high-resolution video work on a budget. All that's left to ask for is faster external storage and better SSDs, but for now it still comes highly recommended.
