Il sito web Phoronix ha pubblicato una interessante recensione della scheda video NVIDIA GeForce 7800GTX utilizzata in ambiente Linux. NVIDIA, infatti, parallelamente al lancio della nuova soluzione video in data 22 Giugno, ha reso pubblici i nuovi driver 1.0 7667 per il sistema operativo del pinguino.

Le analisi sono state condotte su due sistemi, una piattaforma Intel 32-bit e una piattaforma AMD 64-bit:

Su entrambi i sistemi è stato installato il sistema operativo FedoraCore4, basato su Kernel Linux 2.6.12 e GNU Compiler 4.0.0. I driver della scheda video sono, come detto in precedenza, il set NVIDIA 1.0-7667.

I risultati, come si legge nelle conclusioni, sono tutt'altro che soddisfacenti:

"Unfortunately, once we witnessed the lackluster performance of the 7800GTX, we were extremely dissapointed. NVIDIA had released new drivers on the same day as the launch of the GeForce 7 series, but its performance was simply missing in action. After seeing our inital results, which were displayed on the previous three pages, we tried the Leadtek 7800GTX on some of our other PCI Express systems, but the Linux performance boost was still minimal compared to the GeForce 6 series. We expect that a majority of the performance downfall is attributed to the 1.0-7667 Linux drivers. After doing some additional testing, we found that the driver problem may be related to a conflict with switching between the 2D and 3D clock frequencies once an OpenGL program is initalized. Once we investigate this issue further and learn any new information relating to the Linux performance, we'll be sure to report back our findings. "
