Performance in Semi-Synthetic Benchmarks
The Sapphire HD 4850 X2 has a higher overall score, over 19,000 points, whereas the Leadtek WinFast GTX 280 only scores 17,000 points. These numbers have little practical value because 3DMark06 is a technically outdated benchmark, but let’s see what we have in the individual tests.
The Leadtek has no advantage even under favourable conditions. We mean the SM2.0 tests that have high-resolution textures and multiple light sources but little mathematics. The difference between the two opponents is only 761 points, though. That’s about 10%.
The mathematics-heavy SM3.0/HDR tests are easier for the Sapphire HD 4850 X2 which boasts 320 shader processors with 1600 ALUs. The card’s advantage grows up 1189 points as the consequence. The individual groups of tests agree with the overall picture. But 3DMark06 is an old benchmark already and we won’t publish the results of its individual tests in our future reviews.
