The mighty-impressive NVIDIA GeForce GTX TITAN was released in mid-February as a graphics card with 6GB of video RAM and boasts 4.5 TeraFLOPS of single-precision compute power and 1.3 TeraFLOPS of double-precision compute power. The NVIDIA 313.26 driver was released to support this ultra-powerful NVIDIA GeForce graphics card under Linux.
Sadly, with an uncooperative NVIDIA PR/marketing department, there's unlikely to be any GTX TITAN benchmarks at Phoronix. The NVIDIA hardware reviews at Phoronix tend to just be whatever the NVIDIA Linux employees buy themselves and send over to Phoronix or most of the time in recent years it's been hardware that I personally buy to review (you can help out via subscribing to Phoronix Premium or making a PayPal tip).
Fortunately, Phoronix Forums moderator "Deanjo" bought the $999 NVIDIA graphics card for himself and has been running some tests. You can find his NVIDIA GeForce GTX TITAN benchmark results with the NVIDIA binary blob doing OpenGL on openSUSE 12.3.
His main GTX TITAN results can be found on OpenBenchmarking.org within 1303113-FO-GEFORCETI80. Click that link for GTX TITAN Linux results from the KDE 4.10 desktop with the Unigine benchmarks, Xonotic, and others. Through the Phoronix Test Suite you can see how your system compares by simply running phoronix-test-suite benchmark 1303113-FO-GEFORCETI80. Discussion and other information can be found within this forum thread where readers should be able to ask him any other Linux TITAN information or other test requests. Too bad though we aren't able to run any GTX TITAN results in-house for an extensive Linux product review.
