Lucid Hydra vs SLI vs CFX: 13 multi-card config tested
 

After managing to activate SLI on Crosshair IV Extreme I decided to study performance scaling of HydraLogix technology vs SLI vs CrossFireX. I wanted to be fair, so I used the SAME motherboard for all the testing.

I have 13 diferent multi-card configurations:

* HD5850 + GTX460
* HD5870 + GTX470
* GTX480 + HD5870
* GTX470 + GTX460
* GTX480 + GTX470
* GTX480 + GTX470 + GTX460
* 2 x GTX460 (Hydra)
* 3 x GTX460 (Hydra)
* 2 x GTX460 (SLI)
* HD5870 + HD5850 (Hydra)
* HD5870 + HD5850 (CFX)
* 2 x HD5870 (Hydra)
* 2 x HD5870 (CFX)

along with each card tested in single-card mode.

charts are a bit unfortunate design wise :(
but results are interesting
for most part SLI/CFX rules the roost, for games were a profile for CFX/SLI is missing/not yet optimized, Hydra can pull ahead

Using the Lucid technology is, on this board, indeed more performant than using SLI/CF

except for gaming ;)
