From my untrained eye, it looks as though there are performance differences. From the user perspective, as I noted in the previous email, rotating the molecule in the aqua version using the laptop feels jerky. However, I also did benchmarks on my imac, fairly new one with intel dual 2.8 GHz processors, and they are much closer to each other. These were also forwarded through Help.</div><div> I did not have the Model Panel open.</div><div>Hope this helps.</div><div>all the best,</div><div>g</div><div><br></div><div><br></div><div><br></div><div><div>macbook dual intel gma950 graphics</div><div><br></div><div>aqua</div><div>Molecule 1f4h (33805 atoms):</div><div>Null<span class="Apple-tab-span" style="white-space:pre"> </span>Wire<span class="Apple-tab-span" style="white-space:pre"> </span>Stick<span class="Apple-tab-span" style="white-space:pre"> </span>BStick<span class="Apple-tab-span" style="white-space:pre"> </span>Ribbon<span class="Apple-tab-span" style="white-space:pre"> </span>Sphere<span class="Apple-tab-span" style="white-space:pre"> </span>Ops</div><div>32.5<span class="Apple-tab-span" style="white-space:pre"> </span>14.0<span class="Apple-tab-span" style="white-space:pre"> </span>3.0<span class="Apple-tab-span" style="white-space:pre"> </span>2.8<span class="Apple-tab-span" style="white-space:pre"> </span>9.8<span class="Apple-tab-span" style="white-space:pre"> </span>1.5<span class="Apple-tab-span" style="white-space:pre"> </span>27.8</div><div><br></div><div>X11</div><div>1F4H<span class="Apple-tab-span" style="white-space:pre"> </span>(33805):<span class="Apple-tab-span" style="white-space:pre"> </span></div><div>141.0<span class="Apple-tab-span" style="white-space:pre"> </span>56.0<span class="Apple-tab-span" style="white-space:pre"> </span>5.0<span class="Apple-tab-span" style="white-space:pre"> </span>5.0<span class="Apple-tab-span" style="white-space:pre"> </span>73.0<span class="Apple-tab-span" style="white-space:pre"> </span>3.0<span class="Apple-tab-span" style="white-space:pre"> </span>31.0</div><div><br></div><div><br></div><div><br></div><div>iMac dual intel ATI,RadeonHD2600 graphics</div><div><br></div><div>aqua</div><div>Molecule 1f4h (33805 atoms):</div><div>Null<span class="Apple-tab-span" style="white-space:pre"> </span>Wire<span class="Apple-tab-span" style="white-space:pre"> </span>Stick<span class="Apple-tab-span" style="white-space:pre"> </span>BStick<span class="Apple-tab-span" style="white-space:pre"> </span>Ribbon<span class="Apple-tab-span" style="white-space:pre"> </span>Sphere<span class="Apple-tab-span" style="white-space:pre"> </span>Ops</div><div>60.5<span class="Apple-tab-span" style="white-space:pre"> </span>60.2<span class="Apple-tab-span" style="white-space:pre"> </span>5.5<span class="Apple-tab-span" style="white-space:pre"> </span>5.5<span class="Apple-tab-span" style="white-space:pre"> </span>15.4<span class="Apple-tab-span" style="white-space:pre"> </span>8.6<span class="Apple-tab-span" style="white-space:pre"> </span>36.3</div><div><br></div><div>X11</div><div>1F4H<span class="Apple-tab-span" style="white-space:pre"> </span>(33805):<span class="Apple-tab-span" style="white-space:pre"> </span></div><div>8.0<span class="Apple-tab-span" style="white-space:pre"> </span>102.0<span class="Apple-tab-span" style="white-space:pre"> </span>3.0<span class="Apple-tab-span" style="white-space:pre"> </span>3.0<span class="Apple-tab-span" style="white-space:pre"> </span>8.0<span class="Apple-tab-span" style="white-space:pre"> </span>4.0<span class="Apple-tab-span" style="white-space:pre"> </span>39.0</div></div><div><br></div><div><br></div><br><div><div>On Jun 2, 2008, at 11:29 AM, Thomas Goddard wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Hi Glenn,<br><br> I compared the molecule rendering speed with Mac X11 and Mac Aqua Chimera snapshots (version 1.2524) and found them to be the same on an Intel Mac PowerBook with Radeon X1600 graphics and on a Power Mac G5 with Radeon ATI 9800 pro graphics.
