They have to go through QA testing and such you know. I also wonder if the last-minute R9 290 fanspeed change had something to do with it.
You mean like how the preorders for the 290X were going to start on Oct 3 without any product specifications and then were delayed to October 15? Then proceed to delay the 290 launch? All the while stringing along the customer base and suggesting that they are launching a product that will "ridicule" the Titan only to discover that the cards are within margin of error? AMDs marketing department has oversold and under-delivered for too long. Such tactics may be worthwhile if they were the frontrunner in this industry but the truth is that Nvidia is dominating the market with nearly 2/3 the market share in discrete graphics.
Ultimately, AMD has failed to deliver products for the mainstream population for this holiday season. They failed on both the graphics and CPU fronts this year. The delayed launch of Kavari to Q1 '14 and the mainstream versions of the Hawaii chips being delayed to either within a week of Christmas or after ensures that consumers go with their competitors this holiday season. The only only competitive products that AMD has on the market are now 2 years old and are at the end of their life cycle and Nvidia has successfully countered their prices and added a better gaming bundle for the holiday season why AMD continues to hold onto the same promo with the same games that have been available for nearly a year. If this isn't intentional hemorrhaging then I am unsure what else it could possibly be... It seems that in efforts to provide ample supply for the PS4 and Xbox One, AMD has successfully forfeited the PC market.
According to that graph nVidia has lost more market share year over year than AMD has.
But the R9 290 has nothing to do with overall market share. Top end cards amount to a few percent of total GPU sales at the best of times.
That graph is for total graphics which includes portable devices. Nvidia continues to lose shares in the mobile market to AMD and Intel's integrated graphics solutions(read the
full report). Nvidia has gained .5% market share YTD (see above graph) for discrete cards. To end cards don't amount to a large share of total sales, correct. However, top end cards to have an effect in swaying a buyer to purchase a particular brand. Every review has highlighted the performance superiority of Nvidia's high end cards over the last year and this propagates the belief that Nvidia cards are superior. Furthermore, AMD has had no new products on the market for 2 years and their launch of the 7790 was dethroned within a few weeks of release. The same has occurred with the 290X. After finally releasing a successor to the 7970 after two years, the reviews all declared the product a solid performance rival to the Titan but noted that it was noisy and ran hot. A few weeks later, Nvidia releases the 780 Ti and once again takes the throne of top performer and this time around the price gap between the 290X and the Titan successor was $150 as opposed to $450 and the package that Nvidia delivered was much more polished whereas the 290X looks rushed with its inept cooler. If you end up with nothing but rebranded cards for the low and mid range cards and they are all within performance and price of each other as they are now, the average consumer will go with the more familiar of the two products. It also doesn't hurt that Nvidia now has the better gaming bundle.
