Nvidia Tegra 2 - Graphics Performance Update
So I have a confession to make. Before we posted our Tegra 2 performance preview, I ran the Quake 3 demo on the Viewsonic G Tablet and the Samsung Galaxy Tab three times each, ran the averages, and ended up with 49.1 fps for the Viewsonic and 32.1 fps for the Galaxy. Based on some input from Imagination and other Galaxy Tab users, we decided to retest the Galaxy Tab, since our results were a good bit lower than what they were reporting.
And on re-running the Quake 3 benchmark, I got results in the 44.9 - 46.0 range. I ran it over 50 times trying to replicate the previous scores, but under no conditions (settings, background applications, etc) could I get anywhere near my previous result. I know for a fact that the settings were all correct and that there were no previously running applications, so I really have no idea why I got a framerate that low, much less why it was repeatable.
In addition to retesting Quake 3 on the Galaxy Tab, I also ran both slates through GLBenchmark 2.0, which we recently added to our benchmark suite. The combination of the two gave me enough reason to write up an update to our Tegra 2 performance preview from two weeks ago.
