Spec ViewPERF 7.0

Theoretical benchmarks are one thing, we mentioned this already earlier, however, there are also some professional OpenGL applications like for example SPEC.org ViewPERF suite. Since we have posted results for the nVidia Quadro already in about a dozen different reviews, we reason that it is only in the interest of the reader to show the data here as well, otherwise, we could just refer to all the earlier reviews and boost our page views but who cares about those anyway?

The nVidia Quadro4 GXL980 (red columns) leaves very little doubt about who is the top dog here. Even though the card in question is based on the GeForce4 Ti4600 and as such almost a museum piece, it beats the Wildcat in every single discipline except for ProE-01. Keep in mind here that this type of CAD application is not necessarily the targeted market for the Wildcat VP990, the models used are not large enough to even stress the frame buffer of the Quadro4 with its 128 MB DDR SDRAM which is why, by definition, there is no incentive to use 512 MB of onboard memory, and no benefit either.

The burning question on everybody's mind of course is, how much performance is clipped and culled by the slow memory interface?

Increasing the memory speed from 150 MHz to 160 MHz (6.6%) boosts the performance by 3.5%, increasing the memory and core clock further turns the wildcat into a cheetah. Unfortunately, this is as far as we were able to push the memory beyond its specs. It would be very interesting to see how fast the card would be at the projected 20 GB/sec or 312 MHz instead of the 150 MHz caused by the parts we were stuck with.
