From: Rob on 16 May 2010 08:15 I've just ripped some DVDs to disk using Handbrake. Using an i5 2.66 iMac it encodes at about 90fps; using a C2D 2.4 iMac about 30fps. Same disk and encoding settings (normal default). I hadn't expected the performance difference to be that great - does it look about right? Rob

As well as the quad core advantage, the Core iX generation are a decent jump ahead of the Core2 chips. I'd have expected a little higher, to be honest.

Of three i5s which I bought one scratches DVD/CDs badly. This isn't cackhandedness but something inside isn't right. It's twatted the install discs for Final Cut Studio and Logic Studio which is a lot of DVDs :-( Googling suggests a problem exists but it's clouded by the possibility of pulling/pushing discs against the aluminium slot.

Mine doesn't, though it's only had about five disks in it since I got it. Three were 4+gig DVDs being burnt, so had full traversal of the platter. It may to be easy to tell the difference between drive internals and externals (that alu slot) being scratchy - internals will cause curved tracks following a circle centred on the hole as the disk is spinning, while externals will be straight lines. The rollers that bring the disk in count as externals for this, mind... I remember a lot of Xbox360's had disk scratching problems, of the curved variety - the read head was ploughing into the spinning disk. Cheers - Jaimie -- aibohphobia, n., The fear of palindromes |
