All you have is the sum of the shares. It might be common becasue it is quick but alone is somewhat meaningless it needs greater context. It's market cap is simply based on speculation, the very act of purchasing shares alters its price as market responds to the demand.
Someone interested in buying the company, or an forming objective estimation of a companies worth for example would use alternate methods to value it.
There are a few ways of valuing a company
Market price. In an efficient market the share price should reflect the value of the company. The markets could be deemed efficient in the long term, but mid to short is debatable.
Equity, therefore net assets less net liabilities. This is pretty basic as it only values tangible assets and ignores intangibles such as internally generated IP, staff etc....
Discounting future cash flows. Look at the cash that is expected to be generated over a period of time discounted to reflect that money in one year is more certain than money in ten years. Sum this and get and you get a valuation.
None of these are wrong and for AMD purchasing ATI I imagine that there were synergies through restructuring that would have seemed mutually beneficial at the time. These need to be factoring in at the time of acquisition to determine the offer. I haven't looked in detail but it seems that owning ATI has kept AMD afloat, although feel free to correct me.
