XFX GeForce GTX 260 640M XXX Video Card Review

Hardware Secrets Silver Award

More Details

To make the comparison between XFX GeForce GTX 260 640M XXX and the other video cards we included in this review easier, we compiled the table below comparing the main specs from these cards. If you want to compare the specs from the reviewed 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, which are lower than the prices we published in other reviews, since prices tend to drop every day. NVIDIA is now pushing their partners to sell GeForce GTX 280 for USD 500 (from the original USD 650 MRSP), GeForce GTX 260 for USD 300 (from the original USD 400 MRSP) and GeForce 9800 GTX for USD 199.

With these new prices the main competitor to GeForce GTX 260 is Sapphire HD 4870, even though video cards based on this AMD GPU can be found costing a little less. The reviewed model from XFX costs, on average, 10% more than the standard GTX 260 since it is an overclocked model.

The only high-end video card not included in our comparison is GeForce 9800 GTX+, which is basically an overclocked GeForce 9800 GTX.

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 uses GDDR5 chips, which transfer four data per clock cycle and thus the “DDR clock” for this video card is four times the value presented on this table (i.e., 3.6 GHz).
  • GeForce 9800 GX2 and Radeon HD 3870 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 and XFX GeForce GTX 260 640M XXX. 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 260 and USD 370.

Before going to our tests let’s recap the main features from XFX GeForce GTX 260 640M XXX.
