RSX Shrinks Next Month
PSthree, come to meeee!

November 26, 2007 - According to a report from Nikkei late last week, Toshiba is planning on switching manufacturing of the PlayStation 3's RSX graphics processor to a 65nm process next month. Currently, the chip is manufacturing using a 90nm process, the same as it's been since the system's launch.

A smaller die size for the chip can mean cheaper production costs and less heat, contributing to lower prices for the consumer, and a quieter, more reliable PS3 system.

The latest versions of the system's Cell CPU are being manufactured using a 65nm process. It is widely believed that the switch to 65nm for the Cell is one of the main reasons Sony was able to drop the PS3's price down to $399 in time for the holidays.

Nikkei also reports that Toshiba is planning on beginning manufacturing at 45nm in the latter half of the next fiscal year, and speculates that the RSX and other PlayStation 3 chips are prime candidates for the new line.

据日经新闻报道，东芝计划在下个月将PS3 RSX图形芯片的制造工艺由目前的90纳米转换成更先进的65纳米。

RSX芯片自发布之日起就一直沿用着老旧的90纳米制造工艺，采用65纳米工艺后将有效缩减芯片的制造成本及发热量，使PS3更安静，更可靠，和更廉价。

业界普遍相信索尼之所以能将40G版PS3的售价拉低至399美元，主要归功于PS3 Cell芯片应用了单位制造成本更低的65纳米工艺。现在，最后一个堡垒——RSX图形芯片，也将迁移至65纳米制程，这将赋予索尼更大的降价空间。

日经新闻还称，东芝计划在下一财政年度的后半段开始应用45纳米工艺，RSX及PS3主机中的其它芯片将是最主要的受益者。
