Intel has increased bonuses for employees refereeing women, minority and veterans in a bid to improve its workforce diversity.

The technology major will offer referral bonuses of up to $4,000 to encourage employees to bring in new hires who would help the company improve its workforce demography.

Previously, the chipmaker announced that it will spend $300m over the next five years to address the diversity gap, and has set a goal to have "full representation" of women and under-represented minorities in its US workforce by 2020.

In March, Apple committed to provide $50m to non-profit organisations who work to bring more women, minorities and veterans to the tech industry.

Google announced its workplace demographics data in June, which highlighted that 21% of its tech hires last year were female.

The Wall Street Journal cited Intel as saying: "Intel is committed to increase the diversity of our workforce.

"We are currently offering our employees an additional incentive to help us attract diverse qualified candidates in a competitive environment for talent."

In its diversity statistics released last year, the company said that only 24% of its employees were female and most employees were White and Asian.
