how can this be a attempt to up the price for AMD
this deal is already signed...
it may be a attempt to up ATI's stock price
anyone with even a basic knowledge of ANTI-TRUST .. knows INTEL could never buy ATI.... it wouldnt be allowed
The deal still need to be approved by shareholders of both companies (AMD and ATI). If Intel offers more money for ATI shares, then ATI shareholders could decide to sell their shares to Intel regardless of any executive management signed agreement. If ATI were not a public company, then there would be no need to worry about what the shareholders will do. It is also possible that the shareholders can shoot down both offers and keep ATI as it's own company.
Therefore, as I stated above, AMD would need to offer more money and/or more shares of AMD stock to sway ATI shareholders to sell thier shares to AMD. Shareholders have rights and they make their own decisions.
This is assuming the rumor is true.
Regarding anti-trust never allowing Intel to purchase ATI... That is no definitive if a hypethetical acquisition of ATI by Intel would be denied. Yes, Intel will strengthen it's hold on in the chipset market, but there are still chipset makers out there like nVidia, VIA, and SiS.
Regarding graphics, technically there are currently three major players in the graphics chip industry; ATI, Intel, and nVidia. However, only ATI and nVidia are in the "performance graphics chip" sector of the industry. Intel is merely a low level player in the value segement. If Intel were to acquire ATI, then there will still be two major players in the "performance graphics chip" sector.
