AMD Updates Radeon HD 7950 to Thwart GeForce GTX 660 Ti
AMD is preparing to update the specifications of its Radeon HD 7950 graphics processor to make it more competitive in the sub-$400 market segment, particularly against NVIDIA's upcoming GeForce GTX 660 Ti graphics processor. The update is much like that of the Radeon HD 7750, which got its core frequency increased from 800 to 900 MHz in a specifications update. The company released a new BIOS ROM image file which works on all AMD reference design Radeon HD 7950 graphics cards, which implements the new specifications.
The new specifications sees the GPU core frequency increased to 850 MHz (from 800 MHz), and introduces PowerTune with Boost, which sends the GPU clock speed up to 925 MHz, when applications demand it. The memory frequency stays unchanged, at 1250 MHz, and so do the physical specifications of the GPU, such as stream processor, TMU, and ROP counts. All Radeon HD 7950 graphics cards manufactured from mid-August will feature the new specifications, prices will remain unchanged. If you're familiar with manually updating the BIOS, you can check it out (at your own risk) from our VGA BIOS Database. Set your card's BIOS selector switch to "1" (if available), and update the BIOS. It works only with AMD reference-design HD 7950 cards.

简单翻译一下:
新BIOS先是将原先默认的800MHz频率提升到了850MHz,然后再增加了PowerTune功能,可以实现睿频到925MHz,这样一来新的HD7950性能应该和HD7970相差无几,瞬间把GTX 660 Ti的优势给打没了...农企虽然反应慢但怎么说产品本身应该拥有更高的潜力可挖,做成"网卡"模样的GTX 660 Ti要不再加下压"深度"挖掘下超频潜力?作者: MIKU版刀锋 时间: 2012-8-14 20:17
众媒体对GT640的评测逐渐出炉,而个别已经拥有GTX680M的玩家也曝光了她的性能。然而,大家对GT640 vs HD6670以及GTX680M vs HD7970M充斥着种种争论,认为Kepler产品仅仅是跑分好看而已。看到大家热烈的争论,在下发表一点自己的粗略见解,如有错误,还请大家多多指教与原谅。
说些题外话,GK107 DDR3桌面版本的表现显然让大家失望了,以HD7750标准版约91%的功耗(实测50W vs 55W)仅实现80%的游戏性能,偏高的定价更是使她毫无性价比。之后nVIDIA会开始允许下游厂商为GK107搭配GDDR5显存,不过大家也无须作过多期待。那是真正的“灰烬版”,3DMark11 P3000左右,游戏性能最多接近HD7750高频版,价格一样坑人。公版仍不会有6pin,或许能成为相对于大部分HD7750高频版的一个卖点。
