Specifications in brief
We've already dropped the massive bombshell that the X1300 XT shares the same GPU as the X1600 Pro range of cards, so just what is there in the RV530Pro?
Inside RV530Pro there are 12 pixel shaders and 5 vertex shader units. The reference core clocks for X1600 Pro and X1300 XT are both 500MHz. DDR2 memory clocks are 400MHz (800MHz effective). However, while ATI's reference specs for X1600 Pro and X1300 XT are the same, the two cards we have on review today exceed that spec, upping the core clock and implementing GDDR3 RAM. Here's the important info on the two cards, side by side.
| Sapphire X1300 XT Overclock Edition 256MB GDDR3 | GeCube RADEON X1300XT, 256MB GDDR3, Dual DVI, Platinum Edition | |
|---|---|---|
| GPU | RV530Pro | RV530Pro |
| Memory | 256MiB GDDR3 | 256MB GDDR3 |
| Core/Mem clocks | 574/1386 | 560/1386 |
GeCube has managed to create a longer name than Sapphire, but Sapphire's card has a core clock some 14MHz higher. Both use GDDR3, clocked up at 1386MHz; much quicker than the 800MHz DDR2 RAM you'd find on a reference X1300 XT.
The increased RV530Pro core clocks put both of these cards on the fringes of X1600 XT territory, whilst their RAM clocks are X1600 XT reference clocks. How about that? So we have two X1300 XTs, that in a past life could have been X1600 Pros, but could well perform like X1600 XTs. Perhaps we should examine the cards before we get confused?
