Performance in Synthetic Benchmarks

Futuremark 3DMark06

We did not set any records by overclocking the card from HIS. It didn’t reach an overall score of 14,000 points even. There is nothing particularly interesting in the groups of tests, either. Let’s see how the increased GPU frequencies of the Radeon HD 4870 X2 affect the results of the individual 3DMark06 tests.

The HIS card wins both tests. Compare the results of the Radeon HD 4870 X2 and Radeon HD 4850 CrossFire: they are identical notwithstanding the difference in frequencies and memory type.

There is a bigger effect from overclocking in the two SM3.0 tests: 15% and 10%, respectively. Like in the SM2.0 tests, the HIS HD 4870 X2 at the default frequencies is inferior to the Radeon HD 4850 CrossFire configuration. We can’t explain this behavior, especially as it doesn’t agree with the results of our gaming tests.
