Big GPU Shootout – Revisited

PT Boats: Knights of the Sea DX10 benchmark

PT Boats: Knights of the Sea is a stand-alone DX10 benchmark utility released by Akella last year. It is actually a tech demo of their upcoming simulation-action game. This DX10 benchmark test runs reliably and apparently provides very accurate and repeatable results.

We set the only settings options available to us as follows:

DirectX Version: DirectX 10
Resolution: 1920×1600 and 1680×1050 at 60 Hz
Image Quality: High
Anti aliasing: 4x

PT Boats DX10 benchmark, first at 1920×1200:

Here is 1680×1050 resolution:

Let’s look at 1440×900 with the midrange cards:

Our HD 2900 XT gave a genuine slide show and we see that it is probably unrelated to its only having 512 MB of video RAM as our 512MB GTS 250 has no such issues. We see a repeat performance where the HD 4890 clearly beats the HD 4870. All of these cards drop into the 20s at 1920×1200 resolution except for our CrossFire and TriFire and the HD 4870-X2 is held to middle/low 20s for its minimums and trades blows with the  GTX 280.
