MojoKid writes: Apple's late 2013 edition iMacs are largely unchanged in external form, though they're upgraded in function with a revamped foundation that now pairs Intel's Haswell 4th Generation Core processors with NVIDIA's GeForce 700 Series graphics. The Cupertino company also outfitted these latest models with faster flash storage options, including support for PCI-E based storage, and 802.11ac Wi-Fi technology, all wrapped in a 21.5-inch (1920x1080) or 27-inch IPS displays with a 2560x1440 resolution. As configured, the 27-inch iMac reviewed here bolted through benchmarks with relative ease and posted especially solid figures in gaming tests, including a 3DMark 11 score of 3,068 in Windows 7 (via Boot Camp). Running Cinebench 11.5 in Mac OS X 10.9 Mavericks also helped showcase the CPU and GPU combination. Storage benchmarks weren't nearly as impressive though, for iMacs based on standard spinning media. For real IO throughput, it's advisable to go with Apple's Flash storage options.
