This week we have for you one excitingly interesting test about performance scaling of HD 4890 against 2x HD 4890 in CrossFire mode, with two of the most popular processors in the gaming class of Intel and AMD - Core i7 920 and Phenom II 955 BE. Expect not much talking though, we'll get straight to the tests and their results.

The release of HD 4890 was quite acclaimed in hardware websites. Reviews were mostly positive - swell performance and good price. Respectively 2x HD 4890 became one of the fastest options for AMD/ATI graphic cards fans. so we decided to determine how much of performance boost you get with two instead of one, but with two different platforms. While Core i7 has more rough power - triple channel memory, 8 threads, its processor frequency is 2.66GHz, an the price of the system i s higher (how much you will find in the conclusion), AMD Phenom II 955 BE pulls its load at frequency of 3.2GHz. Right, lets find out what exactly matters for getting more frames in your games.

The common components in both configurations:

  • Sapphire HD 4890 1GB GDDR5 or 2x HD 4890 1GB GDDR5 in CrossFire mode
  • hard drive 1: Western Digital Raptor 10 000RPM 36GB
  • Hard drive 2: Seagate Barracuda 7200.9 300GB
  • PSU: Raptoxx RT-EBAD1200 1200W
  • Cooler: Noctua NH-C12P

Intel Core i7 configuration:


  • Motherboard: MSI X58 Pro
  • Processor: Intel Core i7 920 @ 2.66GHz (133x20)
  • Memory: Patriot Viper Series 3x2GB 1600MHz 8-8-8-24

AMD AM3 configuration:


  • Motherboard: ASUS M4A79T Deluxe
  • Processor: AMD Phenom II 955 BE AM3 @ 3.2GHz (200x16)
  • Memory: Corsair XMS Series 2x2GB 1600MHz 7-7-7-20

The tests were concluded under Windows Vista Ultimate x64. The drivers for the AMD HD 4890 cards were the most recent by the time of the review - ATI Catalyst 9.6 WHQL. the drivers of the motherboards were respectively the most recent ones from the websites of the according manufacturer. Here is the list of the tests we ran:

  • 3DMark Vantage (DirectX 10.1)
  • Stormrise (DirectX 10.1)
  • Crysis: Warhead (DirectX 10)
  • S.T.A.L.K.E.R.: Clear Sky (DirectX 10.1)
  • World in Conflict (DirectX 10)
  • Devil May Cry 4 (DirectX 10)

Without further ado, on to the tests!
