VRAM Analysis 2GB vs 4GB - Thief

Thief Frame 2GB vs 4GB


Above, the percentile chart of the 55 seconds gaming @ 2560x1440. Here we plot FPS and place it in relation to percentiles.

  • 960 - 50% of the time measured frames is doing roughly 32 FPS, so that is the average framerate (high = better). 

As you can see the average performance in-between the 2GB and 4GB is extremely close overall, but do you see that dip at the end in grey? That is the percentage of lower FPS at 2GB compared to 4GB. This is indicative that there is something going on.

In the lower frame-time chart we can analyze and see that perfectly:



The first 15 seconds of the Thief benchmark sequence are difficult with the rain and everything. That results in small stutters and hitches, all cards tested show this visibly on screen so this is game engine related. However, the 4GB card managed this a lot better as there is way less stuttering going on.

Thief at 2560x1440 eats away close to 3 GB of graphics memory here, and yeah it makes a relative difference. 

For those that do not understand what you are looking at, the above is a gametime scene recorded for 55 seconds. With this chart, lower = better. Spikes above 40 ms to 50 ms can be considered a problem like a stutter or indicate a low framerate.
