根据欧盟委员会发布的《2018年欧盟工业研发投资排名》显示，索尼集团在2018年的研发投入在34亿欧元（255.1亿人民币），排名全球第39位。三星电子位列榜首，前五十中唯一上榜的中国企业是华为，排在第五位。 索尼之前表示，PS5的开成成本超过311亿日元（约合人民币18.8亿元），这样计算，PS5的开发成本仅占了索尼去年总研发成本的7.4%。SIE作为索尼多年以来的王牌部门，无论是营业额还是利润都是集团内部的NO.1，仅投入7.4%的研发成本，可以称的上低投入、高回报了。
Sony Group ranked 39th in the world with R&D investment of 3.4 billion euros (25.51 billion yuan) in 2018, according to the European Commission's "EU Industrial R&D Investment Rank 2018". Samsung Electronics ranked first, and Huawei was the only Chinese company in the top 50, ranking fifth. Sony had previously said that the PS5 would cost more than 31.1 billion yen ($1.88 billion) to start up, so the development cost of the PS5 accounted for only 7.4% of Sony's total R&D cost last year. As Sony's trump card department for many years, SIE's turnover and profit are all NO.1 within the group. It only invests 7.4% of R&D cost, which can be called low investment and high return.
