Nvidia initial batch of GeForce GTX 400 series to have fewer cores than expected
Latest news Monica Chen, Taipei; Joseph Tsai, DIGITIMES [Monday 22 March 2010]
Nvidia's initial batch of GeForce GTX 480/470-based graphics cards will have fewer cores than the originally expected 512 due to low 40nm yield at Taiwan Semiconductor Manufacturing Company (TSMC), according to sources from graphics card makers.
Since TSMC's 40nm yield currently is still lower than 50%, Nvidia will block some of the graphics cores with problems on the card. As a result, the GeForce GTX 480 will only have 480 cores and GTX 470 only 448, the sources noted.
The sources pointed out that Nvidia will start selling its GeForce GTX 400 series on March 26, but volume shipments will not start until April 6. The sources also noted that GeForce GTX 480 will be priced at US$499 and GeForce GTX 470 at US$349.
Nvidia has declined to comment on unannounced products
I feel like Ben Stein in Ferris Bueller's Day Off:
Economics Teacher(Ben Stein): In 1930, the Republican-controlled House of Representatives, in an effort to alleviate the effects of the... Anyone? Anyone?... the Great Depression, passed the... Anyone? Anyone? The tariff bill? The Hawley-Smoot Tariff Act? Which, anyone? Raised or lowered?... raised tariffs, in an effort to collect more revenue for the federal government. Did it work? Anyone? Anyone know the effects? It did not work, and the United States sank deeper into the Great Depression. Today we have a similar debate over this. Anyone know what this is? Class? Anyone? Anyone? Anyone seen this before? The Laffer Curve. Anyone know what this says? It says that at this point on the revenue curve, you will get exactly the same amount of revenue as at this point. This is very controversial. Does anyone know what Vice President Bush called this in 1980? Anyone? Something-d-o-o economics. "Voodoo" economics.
