Last month, Nvidia introduced its GeForce GT 640 graphics card, one of the cheaper models based on the new 28nm 'Kepler' chip. The GT 640 is based on the GK107 core, a small chich with 384 shader units (two clusters of 192 each), and a 128-bit memory interface. Nvidia partner Point of View initially launched a single card based on the GT 640, which featured an alternative single-slot cooler.
The manufacturer has now announced a version of the card with increased clock frequencies, the GT 640 'Ultra Charged'. The hardware of this new card is identical to the one that launched a month ago, but the core is clocked at 1006 MHz, roughly 10% faster than the 901 MHz of a reference model. The GDDR3 memory has an effective clock frequency of 2020 MHz, also quite a bit faster than the standard 1782 MHz.
It remains questionable whether the 10% difference in performance will make a big drifference, as with 384 shader units, the GeForce GT 640 simply isn't meant to run the latest games in high resolutions. Point of View has specified a recommended price of €115 (£90) for its new graphics card.
