The graphics cards are listed in the diagrams in the order of ascending price. The results of Radeon cards are marked with red while the results of GeForce cards are marked with teal. Thus, the graphics cards are listed like follows in the tests:
- Radeon HD 4870 512MB 750/3600MHz → 845/3920MHz
- Radeon HD 4870 1024MB 750/3600MHz → 820/4152MHz
- GeForce GTX 260 896MB 575/1242/1998MHz → 702/1459/2484MHz
- GeForce GTX 266 896MB 575/1242/1998MHz → 663/1404/2484MHz
- GeForce GTX 280 1024MB 602/1296/2214MHz → 696/1514/2640MHz
First go the two synthetic benchmarks.
There are no surprises in 3DMark06. There is no difference between the two Radeon HD 4870 when no image-enhancing methods are used. But when full-screen antialiasing and anisotropic filtering are turned on, the card with the double amount of memory goes ahead. It doesn’t overtake the GeForce GTX 260/216SP, though. The latter is also 3-4% faster than the ordinary GeForce GTX 260. So, there is nothing particularly interesting about these results.
The newer version of 3DMark agrees with the previous one. The Radeon HD 4870 1024MB is but slightly faster than the reference Radeon HD 4870 512MB. Both cards are somewhat slower than their opponents from Nvidia. The diagram indicates that Nvidia’s solutions show better scalability with the growth of the frequencies than AMD’s cards.
Unigine Tropics Demo
This technical demo suggests that the Radeon HD 4870 are faster than their opponents. The top-end GeForce GTX 280 is somewhat competitive to the leaders at 1280x1024 without FSAA and AF, but loses in the higher-quality mode. Both versions of GeForce GTX 260 are on the losing side here. Note that there is no difference between the two versions of Radeon HD 4870 with different amount of graphics memory. The new GeForce 260 (with 216 streamed processors) enjoys a solid advantage (up to 20%) over the older GeForce GTX 260 (with 192 streamed processors).
