Here are the pictures of the Radeon HD 4850 and 4870, both powered by the RV770 GPU.
Voici les images des Radeon HD 4850 et 4870, toutes les deux équipées du GPU RV770.
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.
The new version of GPU-Z is out. GPU-Z is a lightweight utility designed to give you all information about your video card and 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.
This month’s edition of “The Digital Eye”, Peter Plantec chats with Paul Debevec about his latest research projects involving realtime 3-D display and capturing and rendering human faces, including a new skin rendering technique.
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.
The guys at Bjorn3D have reviewed Asus’s Radeon HD 3870 X2.
Read the review HERE.
The performance of this card places it in the middle of the pack just under the 8800GT and above the HD 3870 and 9600GT. You can run many of today’s games with pretty good performance levels. Once you enable AA, the situation changes and this card suffers a pretty big hit.
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.
