The GeForce 4 series is a series of desktop - graphics chip company Nvidia and successor of the GeForce 3 series . It is considered to be one of the most commercially successful graphics card series ever. A direct competing product was the Radeon 8000 series from ATI Technologies . The successor is the GeForce FX series .

Technical

The GeForce4 Ti is a direct further development of the GeForce3 Ti and was intended for the demanding player. In contrast, the GeForce4 MX intended for beginners is based on a revised NV11 of the GeForce 2 series , which among other things contained the improved memory controller of the GeForce 4 Ti model. As a result, the GeForce4 MX have no pixel and vertex shaders , but only a hardware T&L unit . Therefore, the MX models of the 4 series are DirectX 7 cards, whereas the Ti models are DirectX 8 cards.

Graphics processors

Various graphics processors are used within the GeForce 4 series, which differ mainly in terms of their 3D capabilities and their graphics pipeline configuration. All graphics processors of the GeForce 4 series have a native AGP interface. NV19 was a marketing name for an NV18 sold with a PCIe bridge chip.

NV28		63 million	k. A.	4 × 2 × 2					AGP 8x

Naming

Within the two segments MX (mainstream models) and Ti (high-end models) the order of performance is identified with a three (MX) or four-digit (Ti) number. A higher number means a more powerful graphics chip. The SE designates reduced-power versions of the graphics chip with the same number. PCX refers to a graphics card with a bridge chip for use in PCI Express systems .

Note

• The specified clock rates are those recommended or specified by Nvidia. However, the final determination of the clock rates is in the hands of the respective graphics card manufacturer. It is therefore entirely possible that there are or will be graphics card models that have different clock rates.
