Sapphire HD7770 1GHZ Overclock Edition Review

Unigine provides an interesting way to test hardware. It can be easily adapted to various projects due to its elaborated software design and flexible toolset. A lot of their customers claim that they have never seen such extremely-effective code, which is so easy to understand.

Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced Unigine engine from Unigine Corp. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. Interactive mode provides emerging experience of exploring the intricate world of steampunk.

Efficient and well-architected framework makes Unigine highly scalable:

  • Multiple API (DirectX 9 / DirectX 10 / DirectX 11 / OpenGL) render
  • Cross-platform: MS Windows (XP, Vista, Windows 7) / Linux
  • Full support of 32bit and 64bit systems
  • Multicore CPU support
  • Little / big endian support (ready for game consoles)
  • Powerful C++ API
  • Comprehensive performance profiling system
  • Flexible XML-based data structures

We use the following settings: 1920×1080 resolution. Anti Aliasing off. Anisotrophy 4, Tessellation normal. Shaders High. Stereo 3D disabled. API: Direct X 11.

The considerable overclock helps to boost the Sapphire card scores by around 4 frames per second, when directly compared to the reference card. Due to the improved tessellation performance with the 7000 series cards, in this particular benchmark the overclocked Sapphire HD7770 outscores the HD6950.

  1. Good card, but I cant help but feel this range of cards from AMD is rather dull and lifeless. why remove alot of the shaders on the cards? makes no sense to go back a step. negates the gains from the manufacturing process and increasing the clock speeds

  2. Very dull launch day, they need to drop the prices.

  3. Sapphire always do good coolers, but id love to know who in AMD thought it was a good idea to lose 140 stream processors on the new card? the HD6770 had 800 !

  4. Crossfire performance is really good. id like to see results from two of the OC’d models.

  5. great cooler, but the card undeneath hasn’t hit the spot im afraid.

  6. I can’t see anybody in the UK listing a Sapphire SKU with 1150Mhz Core clock…
    see Scan/Dabs have a 1120 listed…

  7. Hi Muppett, you aren’t the first person to ask me about this, and ive contacted Sapphire today and they told me that SCAN have the core clock speed listed at the older speeds. It should be 1150mhz. you will hopefully see this change on SCAN Shortly.

    Thanks for letting us know.

  9. This card works best underclocked if you have a clocked version, some of the overclocked 7770’s have an odd issue that causes your screen to flicker. Performance wise its a good mid/entry range card but a complete failure from the 6000 series. One thing does stand out about the 7000 series though, their using better cooling which would be a nice addage if only the prices would drop.

    @Frank I would guess it has to do with the dye shrinkage from 40nm scale to 28nm, I would have settled for a thousand stream processors if it meant abandoning such a useless shrinkage. My guess they shrunk the dye in order to control heat and leverage power out put. Which is just piss poor marketing strategy if you ask me.
