If you want to compare the specs of the reviewed video card to any other video card not included in the table below, just take a look at our NVIDIA Chips Comparison Table and on our AMD ATI Chips Comparison Table.

It is important to note that this table reflects the current prices for the listed video cards at Newegg.com, which are lower than the prices we published in other reviews, since prices tend to drop every day.

Some important observations regarding this table:

  • All NVIDIA chips are DirectX 10 (Shader 4.0), while all AMD/ATI chips are DirectX 10.1 (Shader 4.1).
  • The memory clocks listed are the real memory clock. Memory clocks are often advertised as double the figures presented, numbers known as “DDR clock.” Radeon HD 4870 and Radeon HD 4870 X2 use GDDR5 chips, which transfer four data per clock cycle and thus the “DDR clock” for these video cards is four times the value presented on this table (i.e., 3.6 GHz).
  • GeForce 9800 GX2, Radeon HD 3870 X2 and Radeon HD 4870 X2 have two GPU’s. The numbers on the table represent only one of the chips.
  • All video cards included on our review were running at the chip manufacturer default clock configuration (i.e., no overclocking), except Sapphire Atomic HD 3870 X2. The official core clock for Radeon HD 3870 X2 is 825 MHz, while the official memory clock is 900 MHz. So this card was a little bit overclocked. We couldn’t reduce these clocks to their reference values and since we hadn’t any other Radeon HD 3870 X2 available we included this video card anyway.
  • Prices were researched at Newegg.com on the day we published this review.
  • We couldn’t find Sapphire Atomic HD 3870 X2 for sale. This model will be more expensive than cards from other vendors based on the same GPU because it features water cooling. Just for you to have an idea, prices on the regular Radeon 3870 X2 are quoted between USD 160 and USD 275.

Before going to our tests let’s recap the main features from Sapphire Radeon HD 4830.
