The first codename, GF104, has been doing rounds in the rumour mill ever since GF100 was first announced. Simply put, it will be the GTS 400 series, or, GTX 400/GF100 roughly cut in half. It has been rumoured for 256 shaders. However, the “uncore” part, i.e. memory interface, ROPs, etc. are likely to end up closer to GTX 400, than half.

GF104 is likely to be sized at 300+ mm2, around the same as Cypress, which is a whole class higher. Performance for the top part is expected to be somewhere around the HD 5830. That brings us on to the more interesting codename – GF119.

It is possible this is a revision of the GF10x series. If you remember, the 40nm GT200 derivatives were named GT21x. The reason why they weren’t named GT20x or GT20xb is likely because they were a further shrink to 40nm, from the GT200b 55nm parts.

Similarly, GF11x is likely to be a revision – whether a base layer respin at 40nm or a 28nm, part. However, the last number – 9 – is something new. In the past, the GT21x series has ended with GT218. So, it is possible GF119 is a completely entry level part. SemiAccurate’s sources report that GF100′s yields are still below 20%. In any case, judging by the rampant delays, the extreme power consumption/thermals, missed clock/spec targets, etc., it is clear that something is not quite right with GF100. Perhaps, starting all over again with the basics – GF119 – might be a good idea at this stage. But of course, this is an early rumour and must be considered as nothing more than a rumour.

For the time being, however, GF100, i.e. Nvidia Geforce GTX 400 must hit stores. Availability patterns will give us a clear indication on how deep rooted GF100′s problems really are.
