    Radeon HD 5000 Anisotropic Filtering examined 16x AF

    When AMD launched the HD5000 series, also known by their collective codename Evergreen, they were proudly directing attention to the improved anisotropic filtering, more specifically two things:
    Texture attribute interpolation was moved from the TMUs into the shader core and the angle dependency had almost vanished. The approriate screenshot from a little application known as AF-Tester was shown and repeated through most of the reviews in the internet world. Even though AMDs offerings of late exhibit a more pronounced tendency towards shimmering in fine grainded texture detail, some reviews and reputable magazines declared them ruling kings of image quality - something the fanboys from the red camp really liked and re-trumpeted around the forae of the internet.

    Today, Nvidia launched it's hitherto smallest member of the GF10x architecture and also the Fermi family dubbed Geforce GTS 450.

    It is based upon a 15x15 mm ASIC called GF106, which boasts 4 Shader Multiprocessors (SM) in one GPC and features the same characteristics as the successful Geforce GTX 460 chip GF104. 48 ALUs - called Cuda-Cores by Nvidia - and eight texture units reside in each SM resulting in 192 ALUs and 32 TMUs across the chip. Also, GF106 has a GDDR5-interface comprised of 3 64 bit channels, each hardwired to an octo-ROP, albeit only two of those are active in currently announced GTS 450 products. ...
