Asus Radeon 1950XTX

First Card To Use GDDR4
Runs Significantly Cooler
Incremental Performance Upgrade
Expensive

In terms of changes, the Asus ATI Radeon 1950 XTX takes over from the previous generation of Radeon 1900 XTX. The new flagship model is an evolution of the R580 core, which powered the 1900XTX. It adds GDDR4 support, which is a major step forward for the memory clock as it gets bumped up to an awesome 2.000 GHz up from the previous speed of 1.550 GHz. However, that is the only architectural change that has taken place. In terms of clock speed, vertex shaders and Pixel Pipelines processors, there has been no change. It however does get a decent bump in memory bandwidth going to 64.0 GB/s from the earlier figure of 49.6 GB/s and retains its Crossfire capability.

Here is the specification table as compared to its previous iteration

Specification Table

  Asus Radeon 1950XTX Radeon 1900XTX
Core Name RD580+ RD580
Transistor CT 384 Million 384 Million
Core Clock 650 MHz 650 MHz
Vertex Shaders 8 8
Pixel Shaders 48 48
Pixel Pipelines 16 16
Memory Clock 2.0 GHz 1.550 GHz
DDR Memory Bus 256-Bit 256-Bit
Memory BW 64.0 GB/s 49.6 GB/s

Another change that has taken place on the new series is on the HSF front. The HSF is now even more massive which results in this card running cooler than previous generations. This is a good development as previous iterations were beginning to heat up quite ridiculously. Idling the card runs at a core temperature of 58-59 degrees Centigrade, which is a good 3-4 degrees cooler than earlier efforts. While it may not seem much in percentage terms, one has to realize on just how hot these cards run due to their huge sizes and power requirements.
