The battle of the HTPC cards, Galaxy’s GT 520 vs. HD 6450 (GDDR5 vs. GDDR3)
Heaven 2.5 Unigine
Finally we come to our last benchmark, Heaven 2.5, on the Unigine engine. It uses DX11 and heavy tessellation which will strain any graphics card. At least two DX11 games based on Unigine are expected to be released this year. We use the setting for “normal tessellation” and “medium shaders” and we also set AF to 16x. We will tell you right now that this test chokes the GTX 590 at the highest settings and resolution so we do not run it even at 1920×1200 for lesser cards. Here are our results at 1680×1050.
It is a slideshow Now let’s still look at 1280×720 but drop our shaders to “low” and our tessellation from normal to “moderate”:
The GT 520 is significantly faster than the HIS HD 6450 although the GDDR5 version trades blows with the overclocked Galaxy card. However, this is a synthetic benchmark and we will withhold judgment until we play PC games using the Unigine engine.
