Clock speeds will vary from laptop to laptop. If you have a laptop with this chipset in it, please drop me an e-mail letting me know what your clock speeds are.

Got me a Dell E1505 with this in it. Here's what Catalyst is telling me now though obviously things are down-clocked at the moment:

Graphics Card Manufacturer Powered by ATI
Graphics Chipset ATI Mobility Radeon X1400
Device ID 7145
Vendor 1002

Subsystem ID 2003
Subsystem Vendor ID 1028

Bus Type PCI Express
Current Bus Setting PCI Express

BIOS Version 009.012.001.009
BIOS Part Number BK-ATI VER009.012.001.009.018652
BIOS Date 2006/03/29

Memory Size 256 MB
Memory Type HyperMemory

Core Clock in MHz 209 MHz
Memory Clock in MHz 135 MHz

Primary Display Yes

In the T60, The X1400 has 128MB dedicated (I'm guessing on a 128bit bus, due to performance being higher than my old Radeon 9600 Pro) and then extends to 512MB through Hypermemory. The CCC is reporting clockspeeds as 392/342(700 DDR).

Its a decent chip for older DX9 games. The newest ones don't run well at all, but games like Far Cry will run at 1400x1050 with medium settings well.

My friend's laptop says that it's X1400 has 512 MB VRAM.

dell inspiron e1705 clocks are 432 mhz core 396 mhz memory and it has 64 bit memory bus not 128 bit memory bus. using optimal battery life settings of powerplay in catalyst control center downclocks the x1400 to 324 mhz core and 131 mhz memory.
