Installation
Installing the 3D Prophet 4500 64 MB card was very easy and I didn’t encounter any problems: I simply unplugged (before I have removed its specific drivers) the 3D Prophet II MX and replaced it by the latest 3D Prophet 4500 64 MB from Hercules. Then I plugged on it a Sony Trinitron 17” monitor and start the computer. After Windows 2000 SP1 started, I was prompted to insert the CD containing the drivers for the card. The latest drivers 7.89 were installed easily and one reboot later I was able to discover the new possibilities offered by the 3D Prophet 4500 64 MB and above all benchmark it. 2D Features If most of the 3D Prophet 4500 64MB buyers attend high performance in 3D mode that doesn’t mean standard 2D features don’t count. Indeed playing game is one thing but surfing the web, touching up pictures, mounting movies require good 2D quality. In this area the card is a bit weak. In fact its onboard Ramdac looks like a dinosaur since its only a 270 MHz one. To compare the Matrox Millennium G450 offers a 350MHz Ramdac! With such a Ramdac the 3D Prophet 4500 64 MB card isn’t able to let customers use high refresh rates in high resolution modes. Anyway the 120Hz resolution in 1024*768 32 bit sounds sufficient to me (even if it’s not much when you know that the 3D Prophet III maximum resolution reaches 240Hz in 1024x768 32 bit mode). For the record, the minimum acceptable resolution is set at 75 Hz: under this rate the screen will kind of hurt your eyes.
During our tests the visual quality in 2D mode didn’t reach high levels. Compared Matrox (the outstanding 2D graphic cards maker) or even to any nVidia based card (from GeForce 2 MX to GeForce 3) the colors shown on our screen by the 3D Prophet 4500 64 MB were slightly altered and didn’t respect the original color (for example a defined picture with different levels of blue, red, and yellow colors is much more clearer when displayed by the 3D Prophet 4500 64 MB than with any other graphic card I had the chance to test). If you can obviously correct color tones through the drivers it’s a pity that the default mode isn’t set properly. Another boring thing with this card is that when I plug the Sony Trinitron screen the image displayed in the default resolution of 640*480 was totally misplaced on the screen (half of it was cut). If with any graphic card you definitely have to adjust the image output to fit the specificity of your screen through the screen electronic controls it’s unusual you have to do so much. Indeed generally when showing a 640*480 mode you have nothing to adjust nor in 800x600. You have to adjust the image on your screen (enlarging, centering, etc.) only starting with resolutions like 1024*768 or higher. Support One good point goes to Hercules for its top-notch technical support. The card is warranted for 3 years and you can reach the technical support by phone or email. But another good point goes to Hercules for the drivers. Unlike Creative, Hercules provides their customers with latest Bios or Drivers updates regularly. Best of all the bios or drivers updates are really easy to install since a setup wizard under Windows will guide users doing critical tasks almost automatically. Concerning drivers, Hercules used to diffuse latest drivers based on the ST reference ones but the Hercules drivers differ from the ST ones since they show nice (really!) Hercules & 3D Prophet 4500 64 MB logos. Kyro II Presentation Let’s say directly that this new Kyro II GPU (graphic processor unit) is fully able to compete with GeForce 2 GTS and obviously widely outperforms GeForce 2 MX graphic cards. If the name of the GPU sounds new, the product has already a long history. This GPU is manufactured by a French semi-conductor corporate called ST MicroElectronics. ST MicroElectronics (a corporation issued from the fusion of Thomson Semi-Conductor division & Microelettronica) has teamed up with PowerVR Technologies (a subsidiary of Imagination Technologies, previously known as Videologic) to bring leading edge semiconductor processes. The Kyro II is the result of this association and represents in fact the third generation of the PowerVR processor. First Power VR GPU equipped Matrox M3D graphic cards in 1997 and later on Sega DreamCast consoles. When Sega chose to include PowerVR processors in the DreamCast instead of the 3DFX ones, they didn’t make a mistake when you consider the unprecedented level of 3D graphics quality the DreamCast brought. Thus Imagination Technologies has a long known how in the 3D graphic market. Their first GPU, the PowerVR, came with a revolutionary technology (when it was released a few years ago) called Tile Rendering. The Tile Rendering engine, we’ll review later, made all the interest of the PowerVR GPU and is still present and obviously enhanced in the Kyro II. Now let’s take a look to the 2D features of the card.
