As we read over at AMDZone, NVIDIA announced to the press at E3 show that they would not produce nForce 620/615 chipsets launched and showcased at CeBIT 2002 (see this news story).

As you remember, nForce 620/615 were supposed to support dual-channel DDR333 (PC2700) memory and AMD Athlon/Duron CPUs. Some time ago one of NVIDIA high-ranking officials noted carelessly that the company could introduce the support for DDr400 (PC3200) into its nForce 620/615 chipsets, although that memory type hadn’t been approved by JEDEC then. As we see, there will be neither DDR400, nor DDR33 now…

According to the company representatives from Santa-Clara, the R&D department is focusing mainly on nForce2 chips with the integrated GeForce4 graphics core supporting AGP 8x, DDR333 and other up-to-date features of the kind.

Bearing in mind that Athlon XP processors do not get any extra performance from the dual-channel DDR266 (PC2100) it would be quite logical to suppose that the use of more expensive memory will hardly have a more positive effect on the performance. Here I would also like to point out that the growing bandwidth of the bus will let GeForce2 MX show much better results and will even allow it to outperform the fellow solutions on add-on cards.

Anyway, nForce 615/620 will never arrive into the market for some technical (too complex PCB layout) or marketing (NVIDIA partners have to sell their graphics cards somehow) reasons.
