NVIDIA had pretty hard times with the yields of its GeForce FX family of graphics processors last year, but claims everything is going right this year with the recently introduced GeForce 6800-series of graphics processors.

The NVIDIA GeForce 6800-series of chips unveiled in mid-April are the company’s flagship products in the GeForce 6-series of graphics processors. The GeForce 6-series of graphics processors will be eventually available across entry-level, mainstream, performance-mainstream, high-end as well as so-called ultra high-end graphics cards. The new series of NVIDIA’s graphics processors is the company’s second generation lineup of DirectX 9.0-compatible offerings that greatly leverage the feature-set of NVIDIA GeForce FX graphics chips and brings important additional capabilities, such as Shader Model 3.0, as well as great performance improvements over the previous generation hardware.

While NVIDIA kept its promise to deliver the GeForce 6800-series graphics processors into the market by June, some observers noted that availability of the GeForce 6800-series graphics cards is somewhat constrained. Among possible reasons for the insufficient supplies of the new chips they noted low yields and limited production lines allocation at IBM. Neither of the assumptions was confirmed by NVIDIA’s representatives.

“The ramp up of the GeForce 6800 is complete and we now have product flooding into the partners in large numbers with no supply issues whatsoever. We are confident that you will not find an NVIDIA board partner who would say otherwise,” said Roy Taylor, VP Sales, EMEA.

At this point market tracking agencies do not comment on market shares of NVIDIA Corp. and its main competitor ATI Technologies this quarter. Both companies also remain tight-lipped over the numbers of new graphics processors shipped to the market.
