In navolging van Creative en Guillemot springt ook Leadtek op het Double Data Rate treintje. Net zoals bij de kaarten Annihilator en 3D Prophet is de DDR versie fors duurder: 100 dollar extra, maar dan heb je wel een verdubbelde fillrate. Hier de press release van FPS3D.com:
LEADTEK Research Inc. today announced its new version of the WinFast GeForce256 graphics accelerator with additional DDR technology. While keeping the same set of advanced features the WinFast GeForce256 offers, the WinFast GeForce256 DDR has significantly widened the memory bandwidth to reach workstation-class graphics performance. In addition to delivering superior 3D performance for high-end OpenGL based authoring and CAD applications for Windows NT users, the WinFast GeForce256 DDR also further enhances performance for demanding multimedia applications in the consumer market such as gaming, DVD playback and game authoring under Windows 95, 98 and 2000.
DDR (Double Data Rate), the latest memory technology, is capable of doubling the frequency of data fetching to dramatically increase data transfer throughput. Traditionally, each memory cycle is triggered by either the positive or negative edge in the clock cycle. DDR technology enables both positive and negative edges to initiate the memory cycle, effectively doubling the memory data bandwidth.
By utilizing DDR memory on the already powerful WinFast GeForce256, the speed of buffering and texturing will be greatly increased, thus releasing the bottleneck between the graphics processor and the memory. In an advanced graphics subsystem, instead of using the PC's central processor, massive graphics computation takes place at the on-board GeForce256 processor and its memory buffer; freeing this bottleneck gets particularly important in order to achieve higher graphics performance.
The WinFast GeForce256 DDR will be available at the end of November through Leadtek's distribution channels, and the estimated price will be $100 higher than the non-DDR version.
