ChickenHead writes "AnandTech has put together a review of the Hercules 3D Prophet 4500 based on the new Kyro II chip from STMicro. What's unique about this particular chip is that it uses a Tile-based Rendering Architecture which results in a much greater rendering efficiency than conventional 3D rendering techniques. It is so efficient in fact, that the $149 Kyro II card clocked at 175MHz is able to outperform a GeForce2 Ultra with considerably more power and around 3X the cost of the Kyro II card. With games not able to take advantage of the recently announced GeForce3's feature set, the Kyro II may be a cheap solution to tide you over until the programmable GeForce3 GPU becomes a necessity." A very readable and interesting summary and an interesting technology and a potentially extremely cool video card.
