Matrox Millennium G450

The G450 was manufactured using a 0.18 micron process technology, while the G400 was manufactured using a 0.25 micron process. But if the G400 used a 128-bit memory bus, then the G450 had its bit capacity reduced to 64 bits. To prevent the reduction in bit capacity from affecting performance, cards based on the G450 come with DDR SDRAM, that is, 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 the G400, but given that this is not SDR, but DDR memory, its effective frequency is 333MHz. This frequency provides a memory bandwidth of 2,7GB/s, the same as the G400. This parameter will significantly reduce performance compared to the G400MAX, whose memory frequency is 200MHz.

The core frequency of the new chip was set to 125MHz, which is similar to the G400. In this case, the fill rate is 250 megatexels per second, and this 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 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.

Characteristics of Matrox G450

It's clear to say that the G450 was not the Matrox's savior. The card was not intended for games and turned out to be useful for professionals who need to work with two monitors.
