Name of processor for newest iMac?

Recently ordered my first new iMac in 15 years; a 21.5" with the 2.7 GHz Quad-core Intel Core i5 with the 256 GB SSD upgrade. Is this the 'Haswell' processor? My previous iMac DV SE (2000) served me well up through early 2008 when I gave it to my daughter and her family. Looking forward to the new technology. The vid card in my current Macbook Pro crashed a few days back and I needed a device to back my data up to so it was a no brainer.
