The initial batch of cards is practically all the same, save for a slight clock-bump here or there.
ASUS is going for something different with its Radeon HD 4890, it seems. Ostensibly the same card as everyone else's, the graphics' giant is adding a 'Voltage Tweak' feature, seen before, which lets you increase VCore from the standard ~1.3V to around 1.45V, for better overclocking, the company claims.
The Voltage Tweak Edition will ship with both XT and OC speeds of 850MHz/3,900MHz and 900MHz/4,000MHz, respectively, but should go farther when over-volted via the supplied ASUS SmartDoctor software. Here's hoping for a 1GHz+ core.
Pricing, too, seems competitive, with the regular card available now for £211, including VAT and delivery. It's our favourite Radeon HD 4890 thus far, but we wait for the MATRIX edition with bated breath.
