I'm looking to buy a new GPU with CUDA technology because right now i have a 9800GT and the new cards are coming into my price range.
I'm definitely set on either the 250 or the 450 but there are a few questions I have.
GTS250:
CUDA Cores: 128
Graphics Clock: 738 MHz
Processor Clock: 1836 MHz
Texture Fill Rate: 47.2 billion/sec
Memory Clock: 1100Mhz
Standard Memory: 512MB or 1 GB GDDR3
Memory Interface Width: 256-bit
Memory Bandwidth: 70.4 GB/sec
GTS450:
CUDA Cores: 192
Graphics Clock: 783 MHz
Processor Clock: 1566 MHz
Texture Fill Rate: 25.1 billion/sec
Memory Clock: 1804Mhz
Standard Memory: 1 GB GDDR5
Memory Interface Width: 128-bit
Memory Bandwidth: 57.7 GB/sec
As you can see, the 250 has a substantially higher texture fill rate and memory bandwidth, but the 450 rises above it with its 192 CUDA cores as well as better memory technology with the GDDR5. Also the 250 uses 256 bit memory interface while the 450 only uses 128 bit.
Before i make a decision in buying anything i want to know which of these factors out weigh the others.
Thanks
