Intel's Haswell architecture is up, selling and running for quite some time and since Broadwell is incoming, it does not come as a surprise that Intel has decided to retire no less than seventeen different CPUs based on Ivy Bridge architecture.
The EOL ready lineup include seventeen different models from Intel's Ivy Bridge Core i5 and Core i7 lineup including the Core i5-3330, i5-3330S, i5-3340, i5-3340S, i5-3470, i5-3475S, i5-3470S, i5-3470T, i5-3550, i5-3570, i5-3570S, i5-3570T, i5-3570K, i7-3770, i7-3770K, i7-3770S and the Core i7-3770T.
Although EOLed, the listed CPUs will be available for orders until December 24th and last shipments are expected on June 5th next year.
