Just Cause 2 and GPU Boost investigation
 |
Just Cause 2 is one of the older titles in our suite and uses DX10 visuals. It's no longer cutting edge, but it's still a lot of fun and can be used to cross-reference older reviews.
Wrapping up the benchmark section, the Palit card returns framerates that are very similar to a Radeon HD 7850's and significantly better than a HD 7790 OC's.
GPU Boost?
You may be wondering why the Palit card narrowly beats a reference-clocked Ti Boost in some games and, as reported on the previous pages, sometimes loses out. The explanation has to do with the way in which each GPU Boost-capable card actually increases frequency.
We used GPU-Z to log the per-second frequency of both the review card and the reference board supplied by NVIDIA. GPU Boost takes a number of parameters into account before setting upon a certain frequency in a game, and the table, below, indicates the highest core frequency attained in each real-world title.
Title/card |
Palit OC |
Reference card |
|---|---|---|
| Call of Duty | 1,110.5 |
1,097.4 |
| Crysis 3 | 1,110.5 |
1,110.5 |
| DiRT | 1,097.4 |
1,110.5 |
| Far Cry 3 | 1,110.5 |
1,110.5 |
| Just Cause 2 | 1,110.5 |
1,097.4 |
Keeping it fair, we tested the cards directly after each other. So even though the two cards have different default and GPU Boost ratings, the reference card actually boosts to practically the same levels as the Palit OC. You, the consumer, won't know just how far a particular GeForce card will boost in your system and all you have to go on is the minimum GPU Boost frequency prescribed by the manufacturer, which is 1,072MHz in Palit's case and 1,033MHz for a reference card.
