This chip is presented by Matrox Parhelia 128MB DDR, 220/550 MHz (Retail), AGP card.

Features:

• Matrox Parhelia-512 chip, 220 MHz clock rate, 512-bit bus;
• 128MB DDR SDRAM in 8 Infineon 3.3ns chips, 275 (550) MHz clock rate;
• Peak fill rate in the multitexturing mode is 880 megapixels/sec and 3520 megatexels/sec.
• Vertex Shader 2.0.

Overclocking is currently impossible.

By the end of the month the product belongs to the $334-354 range; supports DirectX 8.0 (partially 9.0); closest rivals: RADEON 9700 Pro (in price, not 3D performance; see the review).

Antialiasing is one of the most important 3D features.

I recommend you to read our Matrox Parhelia analysis again about the new Matrox AA technique. It's actualy up to 16 counts/dot supersampling. But it's performed ONLY (!) for polygon BORDER=1 dots (3-5% of a typical scene).
