Matrox Millennium G450

G450 was already manufactured according to the 0.18 micron process technology, while the G400 was manufactured using 0.25 micron. But if the G400 used a 128-bit memory bus, then in the G450 its bit depth was reduced to 64 bits. In order for the reduction in bit depth not to affect performance, cards based on the G450 are supplied with DDR SDRAM, that is, the theoretical performance should have been at the level of 128-bit SDR memory in the G400.

The G450 memory had a frequency of 166MHz, like that of the G400, but considering that this is not an SDR, but a DDR memory, its effective frequency is 333MHz. This frequency provides a memory bandwidth of 2.7GB / s, like the G400. This setting will significantly reduce performance compared to the G400MAX, whose memory frequency is 200MHz.

The core clock of the new chip has been set to 125MHz, which is similar to the G400. In this case, the fill rate is 250 megatexels per second, which is a regression when compared even with the 333 megatexels of the G400MAX, not to mention the 1600 megatexels of the GeForce 2 GTS, 549 megatexels of the ATi Radeon and 700 megatexels of the GeForce 2 MX. Thanks to the many integrated components, it was possible to significantly reduce the size of the board compared to the G400 and reduce its cost by up to 5.

Specifications Matrox G450

RAMDAC component of 300 MHz gives the following: removes all flickering of the display, ultra-high resolution and color palette.

It's safe to say that the G450 was not Matrox's savior. The card was not designed for gaming and proved to be useful for professionals who need to work with two monitors.
