The title says it all – this article explores the potential of CrossfireX setup using a mid / low range graphic card like the R7 260X.
To make the comparison more complete, I not only pit the R7 260X CFX setup against a HD 7970 (which is essentially an R9 280X, also part of the comparison) but also I threw the HD 7790 1GB CFX into the arena for good measure.

*I didn’t manage to test the R9 on this benchmark.
At the time of this article, the approximate price of the the products used are as follows
– Sapphire HD 7790 1GB OC Dual-X = RM 460
– Sapphire R7 260X 2GB OC = RM 540
– Sapphire HD 7970 3GB Vapor-X = RM 1300
– Sapphire R9 280X Vapor-X = RM 1250
FYI – I’m using the models under the same brand for ease of analysis.
The CrossfireX setup of the R7 260X costs almost 90% of the R9 280X (RM 1080 vs 1250) and it was able to deliver around 80% – 90% on most tests while consuming approximately 90% of power of the R9 280X (2x ~115w vs ~250w).
Suffice to say, the R7 260X CrossfireX is just not worth considering. A more feasible setup would be the HD 7790 CrossfireX setup.
The HD 7790 CFX setup performed very closely to the R7 260X CFX setup despite having only half the VRAM. The HD 7790 CFX setup is 75% the cost of an R9 280X but it was also able to deliver about 80% – 90% of the R9 280X’s performance while consuming ~33% less power (2x ~85w vs ~250w).
One thing that I must also highlight was that in the benchmark above, the R7 260X were clocked a little higher than the HD 7790 so if they were to run at the same clock then the performance would’ve been identical.
If you already have an AMD HD 7790 card, I think adding another HD 7790 card for performance boost is a great move. It’s even more cost-effective if you are able to source for a used unit. Just bear in mind that ideally your board should be able to run x8 / x8 Crossfire mode and your power supply is able to support an additional HD 7790.
In the end, nothing beats a single card setup. If you don’t mind the hassle, just sell off the HD 7790 and get a card like R9 270X and spare the hassle of setting up Crossfire and deal with scaling issues. 🙂
