Op Tresh's site staat een review van Tim Hsu over de Matrox G450. De prestaties van het kaartje zijn niet echt goed te noemen, de GeForce2MX die was meegenomen in de test ter vergelijking blijkt een hoger aantal fps te halen in alle benchmarks. De uiteindelijke conclusie kan je hier vinden.
Besides the die-shrink to 0.18 micron and the 64-bit memory bus change, there are several additional changes that differentiate the G450 from its older brother, the G400. Most of these changes involve the integration of components onto the card.
One of Matrox's big points for the G400, and now for the G450, is the quality of the RAMDAC that is used. What the heck is a RAMDAC? A RAMDAC converts digital signals into analog ones, which are then used by an analog. The G450 has a 360 MHz primary RAMDAC, and a 230 MHz secondary RAMDAC. One of the prime advantages of having a faster RAMDAC is getting very sharp and very fast 2D, with high resolutions and color depths.
Directly related to this are the two integrated CRTCs on the G450. CRTC stands for CRT (Cathode Ray Tube) Controller. Each of the CRTCs can retrieve data from the G450's frame buffer (basically onboard memory) or from system memory via AGP from different locations. Having two integrated CRTCs allows Matrox to offer what is probably the primary selling feature for the G450, their "DualHead" technology.
A lot of people have been wondering what the differences are between Matrox's DualHead technology and NVIDIA's TwinView technology that is going to be offered on some GeForce2 MX cards. The GeForce2 MX does not have an integrated second RAMDAC or TV encoder, so this does require some external hardware. Matrox is building quite a case up of other instances where TwinView can't do everything that DualHead can do, but without TwinView-capable GeForce2 MX cards available, we haven't been able to see or verify too much.
It's hard to drop a new product much lower, as $149 is not an obscene price for a new video card, but for consumers who want 2D and 3D performance rolled into one, a GeForce2 MX presents itself as a better choice. However, this analysis on price really only takes consumers into account. Matrox's concern is going to be how $149 factors into IT/procurement spending by corporations.
Zoals we al in eerdere reviews hebben kunnen lezen zijn de 3D prestaties niet echt goed. Als je echt een die-hard Matrox fanaat bent kun je misschien beter wachten tot de G450MAX of de G800... Anders is de GeForce2Mx misschien een leuke kandidaat, hoewel de beeldkwaliteit misschien wat minder goed is.
