tomshardware今天报道，他们意外评测到了AMD尚未发表的Radeon HD 7830显卡。

tomshardware表示，AMD的AIB厂商之一AFOX，向他们送测了一张“Radeon HD 7850”显卡，但是，评测者发现这张显卡性能无论怎么测试，都要比其它参加评测的Radeon HD 7850性能更低，其性能介于Radeon HD 7770和Radeon HD 7850之间。

通过GPU-Z 0.6.0软件测试发现，这款显卡尽管也是Pitcairn核心，但是流处理器数量只有768个，正常Radeon HD 7850显卡流处理器数量应该是1024个。Tomshardware将其它Radeon HD 7850显卡BIOS刷入这张显卡也无济于事，流处理器数量还是768个，显示AMD从芯片内部已经屏蔽掉2组CU。

查看GPU芯片发现，表面印有1152 ENG字样，而非正常的1151字样，AFOX工程师告诉tomshardware，AMD从3月份开始向部分OEM厂商发送Radeon HD 7830芯片工程样品，供相关显卡开发使用。

tomshardware联系AFOX之后得知，AFOX送错了测试样品，AFOX Radeon HD 7850显卡的确有1024个流处理器，AFOX将重新发送正常的Radeon HD 7850显卡。
