GT200b

Citiraj:
  • The successor for the GT200 chip has already taped out, and it too will be nothing special. Documents seen by the INQ indicate that this one is called, wait for it, the GT200b, it is nothing more than a 55nm shrink of the GT200. Don't expect miracles, but do expect the name to change.

  • Basically, these boards are going to cost a lot of money to make, not just to buy. So, you end up with an expensive chip on an expensive board that makes few if any people money. Fair enough, bleeding-edge parts mean bleeding-edge prices. The problem is that ATi is going to make a chip that competes with GT200, and lines up with it point for point. NV wins big Z Fill, ATI crushes them on Shader Flops. What this translates to in the real world is still up in the air, but it looks like the 770 and the 260 will be about equal for most things.

  • The GT200 is about six months late, blew out their die size estimates and missed clock targets by a lot. ATi didn't. This means that buying a GT260 board will cost about 50 per cent more than an R770 for equivalent performance. The GT280 will be about 25 per cent faster but cost more than twice as much. A month or so after the 770 comes the 700, basically two 770s on a slab. This will crush the GT280 in just about every conceivable benchmark and likely cost less.

  • Any decrease in defectivity due to smaller area is almost assuredly going to be balanced out by the learning curve on the new process. Being overly generous, it is still hard to see how the GT200b will cost less than $100 per chip. Don't look for much cost savings there. The new shrink will be a much better chip though, mainly because they might fix the crippling clock rate problems of the older part.

  • The GT200b will be out in late summer or early fall, instantly obsoleting the GT200. Anyone buying the 65nm version will end up with a lemon, a slow, hot and expensive lemon. In the end, NV is facing a tough summer in the GPU business. nVidia has no effective countermeasure to the R770, the GT200 was quite simply botched, and now they are going to pay for it.

Bez obzira kaj je sve to (ko i većina vijesti s tog portala) jako upitno, ali štivo je i više nego zanimljivo. Ako ništ drugo, malo za razonodu.
