ASUS Radeon HD 7770 DirectCU 1GB GDDR5 Video Card Review

Hi Tech Legion
16 February 2012
  • Summary: The ASUS Radeon HD 7770 Video Card ran cool and quiet, even under load, thanks in part to the 28nm process and the ASUS DirectCU custom cooling solution.  With the use of ASUS' GPU Tweak utility, the performance was further increased by adjusting the core clock to 1220MHz, 200MHz more than the reference AMD design. Moving on to the GCN architecture and on a 28nm process, AMD's mainstream Cape Verde line up are slightly different from the cards we have previously seen.
  • Pros: Extremely quiet, AMD Eyefinity 2.0, Low power consumption, GPU Tweak Utility, 1020MHz stock clock with headroom for more performance tuning, Low temperature, Metal spine for preventing PCB warping, Full sized HDMI port, Support for multiple independent audio streams, PCI-E 3.0, DirectX 11.1
  • Cons: Price

ASUS Radeon HD 7770 DirectCU 1 GB

  • Summary: AMD's new Radeon HD 7770 delivers a substantial improvement over the previous generation HD 5770. The HD 6770 was just a HD 5770 with a "6770" sticker slapped on it, so the upgrade has been overdue. Averaged over all our testing we see more than 20% higher performance from the reference clocked HD 7770 vs. the HD 5770. This puts the HD 7770 on the same performance level as NVIDIA's GeForce GTX 460, or a bit below the HD 6850.
  • Pros: 20% performance increase over last generation, Excellent energy efficiency, Overclocked out of the box, Extremely quiet, No power consumption increase despite overclock, Excellent GPU overclocking potential, Native full-size HDMI & DisplayPort output, Adds support for PCI-Express 3.0 and DirectX 11.1, Support for multiple independent audio streams
  • Cons: Price too high to be competitive, Lower memory OC potential than other cards, Memory overclock is small, CCC Overdrive limits too low, Voltage controller not very overclocker-friendly

  • Summary: Hачнем с анализа Рейтинга ускорителей iXBT.com , который демонстрирует нам функциональность видеокарт друг относительно друга и нормирован по самому слабому ускорителю — GeForce GT 430 (то есть сочетание скорости и функций GT 430 приняты за 100%). Приведем выборку из этого рейтинга. Мы видим, что 7770 в обоих вариантах идет строго за 6850, хотя пока еще цена высоковата, и получается, что 6850 купить будет выгоднее.
