Noko is right. The VE is a "Value" series chip, with some of the features removed. It's like comparing an OEM GeForce GTS to a retail GeForce MX-the GTS is a better performer even in OEM trim. The LE is the full version of the Radeon chip, but with a lower clock speed and Hyper Z disabled in software. Since Hyper Z is disabled in software, activating it is simple. And raising the clock is also simple. The VE has it's T&L engine disabled in Hardware, it can't be fixed.
