VR-Zone独家获悉：AMD已经确定了新款高端显卡Radeon HD 4890的发布时间：4月6日。

Radeon HD 4890基于RV790核心，依然采用55nm工艺生产，相比于现在的RV740 Radeon HD 4870只是一个优化超频版，同为800个流处理器、256-bit显存位宽，其中核心频率从750MHz提高到850MHz，1GB GDDR5显存的频率则从3600MHz提高到3900MHz。

按照AMD的说法，Radeon HD 4890的性能会比Radeon HD 4870高出大约20％，竞争对手直指NVIDIA最强单卡GeForce GTX 285，价格则是199-249美元。

首款采用40nm工艺的核心RV740则会在5月份推出，有Radeon HD 4770和Radeon HD 4750两款型号，从对工程样品的测试看性能会介乎Radeon HD 4830和Radeon HD 4850之间。
