Key features in more detail include:
-
nfiniteFX II engine: The NVIDIA nfiniteFX II Engine incorporates dual programmable Vertex Shaders, faster Pixel Shaders and 3D textures. The nfiniteFX II Engine gives developers the freedom to program a virtually infinite number of custom special effects to create true-to-life characters and environments.
-
Accuview Antialiasing (AA): The Accuview Antialiasing subsystem with advanced multisampling hardware delivers full-scene antialiased quality at performance levels never before seen.
-
nView Display Technology: The nView hardware and software technology combination delivers maximum flexibility for multi-display options, and provides unprecedented end-user control of the desktop experience. nView allows end-users to select any combination of multiple displays, including digital flat panels, analog CRTs, and TVs, and to modify the display properties using an intuitive software interface.
The basic specifications show that the revised Ti 4800-SE is just the standard GeForce4 Ti 4400 with the added 8x AGP feature. The Ti 4800, however, is the standard king-of-the-hill GeForce4 Ti 4600 with 8x AGP support. To complicate matters even further, it may yet be called the Ti 4600 8x. There's no news on nVidia's own website. The naming convention is anything but clear. So we have the standard Ti 4400 clocks of 275/275 (core/memory) with added 8x AGP support.
We saw the GeForce4 Ti 4200s get an 8x AGP makeover. More than just a naming change with 8x AGP support, they all shared common attributes of having 128MB of memory and standard memory speeds of 513MHz (up from 444MHz). Nothing other than a faster AGP speed, a feature that won't show its worth for a while yet, has changed from the incumbent Ti 4400 to the present Ti 4800-SE.
Just to summarise in quick fashion:
Card | GPU Clock | Memory clock | AGP speed |
GeForce4 Ti 4800 /4600- 8x | 300 | 650 | 8x |
GeForce4 Ti 4800-SE | 275 | 550 | 8x |
GeForce4 Ti 4600 | 300 | 650 | 4x |
GeForce4 Ti 4400 | 275 | 550 | 4x |
GeForce4 Ti 4200 (8x) | 250 | 513 | 8x |
GeForce4 Ti 4200 | 250 | 444/500 | 4x |
