AMD Radeon HD 7790 Duel - ASUS vs Sapphire

Test Setup

Test Setup

For those who've been following our reviews, take note that we've replaced our old test rig with a brand new one for 2013. Here are the new specs we'll be running with:

  • Intel Core i7-3960X (3.3GHz)
  • ASUS P9X79 Pro (Intel X79 chipset) Motherboard
  • 4 x 2GB DDR3-1600 G.Skill Ripjaws Memory
  • Seagate 7200.10 200GB SATA hard drive (OS)
  • Western Digital Caviar Black 7200 RPM 1TB SATA hard drive (Benchmarks + Games)
  • Windows 7 Ultimate 64-bit

Here's the list of cards we'll be testing and the drivers used.

  • ASUS Radeon HD 7790 DirectCU2 1GB GDDR5 (AMD Catalyst 13.3 Beta)
  • Sapphire Radeon HD 7790 1GB GDDR5 (AMD Catalyst 13.3 Beta)
  • AMD Radeon HD 7770 1GB GDDR5 (AMD Catalyst 13.2 Beta)
  • AMD Radeon HD 7850 2GB GDDR5 (AMD Catalyst 13.2 Beta) 
  • NVIDIA GeForce GTX 650 Ti 1GB GDDR5 (NVIDIA ForceWare 310.90)
  • NVIDIA GeForce GTX 660 2GB GDDR5 (NVIDIA ForceWare 314.14)

Note 1: We were unable to acquire a reference version of the Radeon HD 7790 in time for this review to accurately pinpoint the reference card's performance, but our experience tells us that the mildly overclocked ASUS and Sapphire cards are more than adequate for this purpose as they shouldn't be much faster than the reference card. In any case, we expect that most consumers will opt for a custom cooler version of the card anyway, due to better cooler design and slightly improved performance.

Note 2: As both the tested cards utilize the same specifications, the ASUS and Sapphire cards posted almost identical benchmark scores. As such, we have grouped them together into one bar for easier viewing on our charts. Overclocking performance, temperature and power consumption are still shown individually.
