Official Specifications: 5363 stream processors, 352 texture units, 128 ROP units, which is two full R9 290X Hawaii core; core frequency up to an amazing 1018MHz, single-precision floating point performance 11.5TFlops (first time in history to break 10TFlops), but note that this is only accelerating limit frequency, and never open the fundamental frequency by convention, is not expected to tall; Memory is a dual 512-bit, the total capacity of 8GB GDDR5, the equivalent frequency of 5GHz, no crazy 16GB.
The strangest thing is power consumption: Typical power consumption of the entire card is 500W, before speculation nightmare come true, but only two of eight auxiliary power connector pin – we know, PCI-E slot, six-pin and eight-pin maximum supply capabilities are 75W, 75W, 150W, ie R9 295X2 this design should only provide 375W, 500W then is how to ensure it? What use special techniques? That motherboard and power supply and how to support?
Card Size: Graphics body length 305-307 mm, for dual-core graphics cards can also be controlled thickness did not say it in a standard double slot.
Through two 38 cm long rubber tube closed external water cooling radiator, radiator itself and the length and thickness of 152.5 × 38 mm, can plug one or two 120 mm diameter fan (comes with one) , plus the thickness of the fan increased to 64 mm.
The external water cooler from Asetek, integrated pump and use a higher thermal efficiency of micro-channels. ASUS ARES II is also used on his home.
Full coverage of basic metal auxiliary back, fixed and cooling effect.
Performance, the official claimed 3DMark Fire Strike can run close to 16,000 points, compared with the single R9 290X can improve by up to 60%.
Performance, appearance and characteristics. Fans are satisfied with it?
