Video Card Testing Methodology

TheTechLounge explains how video cards reviews are done: benchmarking systems, hardware and software used.

Sometimes the photos don’t tell all, so it gets a description. But we all have swanky cameras and will use any excuse to use them. Outside of disasters, like when my office was struck by lightning (seriously!) we’ll use photos that we’ve taken of the hardware we’re testing–unless they suck and the manufacturer’s are super-sexy.

Photoshop will use GPU

GPU acceleration is one of the most significant trends in today hardware industry, opening the doors to an entirely class of software running desktop. What will be possible is fascinating to see on a monitor, nut it is not tangible, if you just hear about it. It appears that the next Photoshop will be one of the first mainstream applications that will tap into the GPU for a speed up. And, at least from what we have seen during a first demonstration, the progress is simply stunning.

NVIDIA has more than 70 million GPGPUs in the market

Nvidia unveiled some interesting data about its progress on CUDA and GPGPU-enabled processors. During the Nvidia Editor’s Day Spring 2008, the company’s CTO disclosed that more than 70 million CUDA-enabled graphics chips (beginning with the GeForce 8-series) have shipped to date. According to David Kirk, Nvidia sees 350.000 CUDA-enabled driver downloads every week, while more than 60.000 CUDA SDK downloads were reported.

NVIDIA Acquires RayScale Software

NVIDIA will be announcing the acquisition of a ray tracing software company called RayScale.

This is an incredibly interesting move and clarifies more of NVIDIA’s stance on merging traditional rasterization and ray tracing techniques, as we saw in our interview with David Kirk, NVIDIA’s CTO.

RayScale was a startup based out of the University of Utah and has built a hybrid renderer that merges the two techniques – all of the reflections in the image they showed were indeed done with ray tracing alone. The engine was not up to real-time frame rates on the images but they said they have spent the last two weeks working on adding features, not performance, and that it should be “no problem” to get his running in real-time.
