The clarification I'm looking for has to do with the core clock and memory clock speeds for the HIS Radeon HD2600 XT 512MB/256MB GDDR3 AGP. According to the gentleman I'd be getting this card from the core clock speed is 400MHz and the memory clock speed is 800MHz. He provided the model number of the card H26XF512AN and the following link to the HIS website to confirm that information:
The core clock and memory clock speed he indicated and supported by the link to HIS surprised me as I thought this video card had a much faster core clock/memory clock speed. As I did some investigating myself, I found this same card listed at newegg and tigerdirect with different specs for the core clock/memory clock speed. Here are the links:
Both newegg and tigerdirect show the specs for the core clock speed to be 800MHz and memory clock speed to be 1400MHz. However, both also show the model number to be H26XF512ANP, which includes a 'P' at the end of the model number that is not shown by the model number found on the video card he has. That model number again is H26XF512AN. Also, the picture he provided of the card looks exactly like what is seen on the newegg and tigerdirect websites.
So, with all that said, my question is this...why the discrepancy in core clock and memory clock speed between the manufacturer's website (HIS) and the two websites selling the product (newegg and tigerdirect)? Could it be that the model number with the 'P' designates a unit with a higher core clock and memory clock speed, or does that 'P' not make any difference at all?
If there is anyone knowledgeable about this, please reply. I only have a short window of opportunity to make my decision.
