This is an old archive page of HWZ prior to revamp. See article on R’s pixel shaders. Customize The Tech Report The X and X series fixes several flaws in the X design and adds a significant pixel shading performance boost. The other models in the X series, the Radeon X and X cards are reduced derivatives of the R core with a smaller die size and less functional units.

Basically what both Avivo and PureVideo do is to make 2D video processing MPEG2 decoding, for example to be done by the graphics chip instead of the CPU, increasing the performance of your system, since it will free your CPU to be doing something else. ATI is launching today their new series of graphic chips based on a new architecture, which we will be explaining its main features in this article.
This provides temporary storage necessary to keep the pipelines fed by having work available as much as possible.
The XT rides on the same basic board design as the XL, but with a larger dual-slot cooler. Using a Linux distribution a series of open source Radeon drivers are available.
The X Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems. Customize The Tech Report Graphics Previous page Next page. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
High quality anisotropic filtering is definitely something that we have begged of NVIDIA and ATI for a long time and we are glad to see it, but the benefits just aren’t that visible in first-person shooters and the like. While scaling-with-aa on the new X series is very good, will it be good enough to make up for the price difference with competitive NVIDIA hardware?
The primary change between R and R is that ATI changed the pixel shader processor to texture processor ratio.
ATI’s X Series: Extended Performance Testing
UVD 7  [d]. The three stalwarts of the new Radeon X family.
ATI’s Next Chapter Early this month, the long wait and intense speculations were finally put to rest. We will look at resolutions from x up to x and antialiasing tests will be included where possible. Retrieved from ” https: It also gains three extra vertex shaders, bringing the total to 5 units.
ATI Radeon X Series – Hardware Secrets
This refers to ATI’s plan to boost the efficiency of their GPU, instead of going with a brute force increase in the number of processing units.
A staggering million transistors are found on the R core, equaling and surpassing many CPUs in terms of transistor count. Unfortunately, due to the programming content of available games, the X is greatly hampered by lack of texturing power. The dual-link DVI output capabilities of the Avivo display engine will team up with a new, more powerful compositing chip on the master cards to make this happen.
So what are some of the atu features that ATI has added for its latest generation such that it got ‘bloated’ in transistor count? CrossFire support for all models. This design allows memory accesses to be far quicker though lower latency by virtue of the smaller distance the signals need to move through the GPU, and by increasing the number of banks per X100. We’ll address it in a future review. You may be wondering when these products will actually be available for purchase.
ATI Radeon X1000 Series
This new series has basically three families, each one for a distinct market segment: Before moving on to the intricacies of the new architecture, we list the technical spec list table of the three new Radeon X series graphics cards that we have evaluated to bring you this article: The test system that we employed is the one used for our initial tests of the hardware.
Three of the cards, including the X XL, should be available todayif all goes according to plan. However, the bottom line is that performance sells video cards. Ruby’s latest nemesis, Cyn, was composed ofpolygons.
ATI has been working for years on a high-performance shader compiler in their driver for their older hardware, so staying with a similar basic design that is compatible offered obvious cost and time savings. Changes necessary for SM3.
