3/18/2001: KYRO II of STM, the last barrier opposite to NVIDIA and ATI
"If there is sufficient cake, we can eat all"; this one seems to be the maxim of STMicroelectronics, the manufacturers of the graphic chip of the Dreamcast. After the announcement that the Sega games console will be left of producing, a good market for the exit of his chips might be the world of compatible, to that there is destined the announcement of the PowerVR KYRO II, the successor of the KYRO.
The new graphic chip has really interesting characteristics as for image quality: Anti-Aliasing to finished screen, render to 32 color bits, Environmental bump mapping and Dot2 bump mapping, multitexture of up to 8 layers... Also, he supports up to 64 MB of memory and has support for earnings and exits of video.
But the most important of this design is the incredible reduction in the traffic of graphic memory (real ballast of some of the most expensive cards of the moment), up to only one third of the habitual thing. This is obtained calculating to the most minimal detail the polygons, renderizando only the necessary information.
STM already has a powerful ally: Hercules (Guillemot) will make cards based on the new chip PowerVR KYRO II. In particular it is a question of 3D Prophet 4500, a card with 64 MB of memory of excellent value for money, since for approximately 150 $ it is capable (in some occasions) of beating the most expensive GeForce2 Ultra (of "only" more than 300 $), being located frequently over the ATI Radeon 64 MB DDR (that is not also cheap, that we say), according to tests realized by AnandTech.
This marvelous yield is due to the fact that Hercules's card has an efficiency almost of 100 % in what with textures (texture fillrate) it refers to painting ratio, while others, like the GeForce2 Ultra, they have an efficiency I half-close 35 %, with what the yield is much minor than it would be necessary to wait. His only one "but" the fact is that it is not provided with engine of transformation and lighting (T&L), with what his yield goes down in those applications that yes support it.
