GeForce GTX 680 regain performance King on the throne, AMD nature cannot be taken lightly here, next-generation dual-core flagship New Zealand-Radeon HD 7,990 is working overtime to catch, TechPowerUp, it was reported that it would be officially released April 17, announced and is not paper, and immediately listed, prices are as high as $ 849 , about RMB $ 5,350 (dare to sell 6999-_-! domestic estimation).
Start by looking at the first real official publicity photo:
Black tone inherited has-a card recent of has always style, but has two points and past of double core video distinct: first is in thermal design Shang abandoned has high-end card usage of turbine fan, but modified into has a center of 70 mm general fan, plus two large thermal tablets against two star GPU core , looks and GeForce GTX 590 almost, also is a bit Radeon HD seven thousand eight hundred-seven thousand seven hundredths series mainstream model of style. It was explained that, although the reason for doing this is because the turbine fan heat better, but noise is too loud, Radeon HD 6,990 loud voices of the dead is any user who does not forget.
Second, see fan “GHz Edition“? That’s right,Radeon HD 7,990 default core frequency and Radeon HD seven thousand eight hundred and seventy-seven thousand seven hundred and seventieths met 1GHz! Radeon HD 7,970 but 925MHz Ah! You know, in order to control the power consumption, heat and temperature, ancient double-core frequency is considerably lower than single-core card card, AMD this time even on the upstream, was in pursuit of the ultimate performance and a bit crazy.
So the heat sink, such a high frequency, do not know how are temperature control?
Look at screenshot GPU-Z 0.6.0. Because the tool itself is developed by TechPowerUp, should also be high on the credibility, recognition is also very comprehensive, is the wrong code a bit.
Shown here are the core frequency is 1GHz, and the memory frequency is 1.25GHz, equivalent to 5GHz, but not very high. Others would have nothing to say, basically doubling is Radeon HD 7,970, stream processor total of 4,096, memory KB 6GB in total.
In addition, Radeon HD 7,990 using fire is a PLX Bridge chip PEX8747 and supports PCI-e 3.0, provides 48 channels, 27x27mm 676-pin FCBGA package, 0.8W typical power consumption, supports the so-called “broadcast” (broadcast), the function is a good fit for two GPU’s parallel.
Auxiliary power supply interface are two eight-pin , output interface will provide a dual-link DVI, four mini DisplayPort.
