Hallo penggemar PowerVR, gimana nih?
Tentang PowerVR Neon250 (harga 106pounsterling), ternyata tidak seimpresive
TNT2 atau G400.
Personal Computer World - Recommended Award - 5/5 (July 1999)
----------------------------------------------------------------------------
-----------------------
PowerVR graphics card with an impressive pedigree: it powers Sega's
Dreamcast console. Personal Computer World Recommended Award.
The PowerVR chipset... uses an unconventional method for rendering images.
Traditional accelerators like Voodoo render a 3D image in it's entirety:
i.e. the 3D image that is immediately visible and other elements which
remain hidden. This results in wasted clock cycles and consumes more
memory. PowerVR uses a series of clever algorithms to analyse the scene
before rendering the image, which is a far more efficient method.
There were drawbacks, though. The original PowerVR chipset depended on the
host CPU to analyse most of the 3D scene and the chipset had compatibility
problems with Microsoft's DirectX5 API.
This second-generation PowerVR Neon 250 has no such problems: this is the
technology that power's Sega's Dreamcast console. An AGP 2X card, it has
16Mb of SDRAM. The 3D image sorting, once handled by the CPU, is now
performed by the graphics chipset.
Advanced features include 32-bit rendering, trilinear and ansiotropic
filtering, and motion compensation for DVD playback. PowerVR doesn't use a
Z-buffer, so memory usage is better than its rivals...
In our 3D Mark 99 Max tests, the Neon 250's score put it well ahead of
ATi's Rage Fury and it was only slightly slower than 3Dfx's Voodoo3 3000.
Its advanced features, high performance and superb image quality make it a
winner.
5 out of 5
Good Points: High performance. Excellent image quality. Advanced 3D
features. Hardware support for DVD playback.
Bad points: No AGP 4x support, but this isn't a major problem.
Conclusion: A powerful, fully featured graphics card that deserves to be a
success.
