Apple has refreshed the iMac line, furnishing its 21.5in and 27in models with Intel's fourth generation Haswell processors, next-generation Wi-Fi and faster flash storage options.
Apple is touting speed boosts on the new iMac models, claiming up to a 40 percent faster graphics performance than previous models according to internal tests. It also says compatibility with 802.11ac Wi-Fi means up to three times faster wireless connections than older models, while PCIe-based flash storage means Fusion Drive is up to 50 percent faster.
Inside the cheapest 21.5in model, there's now a 2.7GHz quad-core i5 processor and Intel Iris Pro graphics. There's also 8GB of DDR3 memory, which can be expanded to 16GB, plus a 1TB hard drive which can be swapped for a 1TB Fusion Drive or up to 512GB flash storage. Prices start at $1,559 from Apple's site, including VAT.
The other 21.5in model starts at $1,849 and boasts a 2.9GHz quad-core i5 chip with a 6MB L3 cache, but can be upgraded to a 3.1GHz i7 processor. There's also an Nvidia GeForce GT 770 M graphics processor with 1GB of GDDR5 memory. Storage options are the same as for the cheaper model and prices start at $2,199 including VAT.
The cheapest 27in version comes with a 3.2GHz quad-core i5 processor and a 6MB L3 cache. It also comes with 8GB of DDR3 memory, configurable to 16GB or 32GB, plus four SO-DIMM slots accessible by the user. Again, there's a 1TB hard drive, which can be expanded to a 1TB or 3TB Fusion Drive or up to 1TB in flash storage. It comes with Nvidia's GeForce GT 755M graphics processor with 1GB of GDDR5 memory. Prices start at $2,199 including VAT.
Finally, the high-end 27in version comes with a 3.4GHz quad-core i5 chip with a 6MB L3 cache, which can be swapped for a 3.5GHz i7 processor. There's an Nvidia GeForce GTX 775M graphics processor, with 4GB of GDDR5 memory, which can be upgraded to GeForce GTX 780M processor.
