This is actually the first X1900 GT to grace the HEXUS.labs, so we'll take a moment to explain the differences between it and other X1900-series SKUs.

There's not really that much difference, in reality. The Radeon X1900 XTX and XT/CrossFire Edition have the same number of pixel and vertex shaders (48 and 8 respectively), differentiated only by core and memory clocks - 650/1550MHz for XTX and 625/1450MHz for XT/CrossFire Edition. The X1900 GT has the slowest clocks of the bunch, running at 575/1200 and sporting only 36 pixel shaders. All 8 vertex shaders remain, however.

Before we give you a look at the card in the flesh, here's the important bits from HIS's product specification:

ModelHIS X1900GT IceQ3 Dual DL-DVI VIVO 256MB PCIe
Pixel shaders36
Vertex shaders8
Fill rate6.9GPixel/s
Memory256MiB GDDR3
Core clock575MHz
Memory clock1.2GHz
Memory bandwidth38.4GB/s
Display options2x dual-link DVI
2x VGA through DVI-A
YPrPb component
S-Video/composite video in/out

Fill rate is under two thirds that of the X1950 XTX with its brand-spanking-new GDDR4 RAM. It'll be interesting to see how much of a performance difference there is between the two cards.

HIS has provided us with all the display connectivity we'd expect of an X1900 series card, with dual-link DVI, along with component output for some analogue HDTV action and even VIVO. Three cheers!
