Ti is there to confuse and allow the card with the pure-bred lineage to garner the press, then hope the unsuspecting to think it rubs off when Nvidia unloading the geldings at the auction. They need all those places so they aren’t wasting chips. Instead of binning to lowest geldings for later as SE or something they are: taking even more time sorting the very best for this Ti, then sorting mainstream yields for the middle ground of a variety of levels to OC, while are looking release the lowest chips almost straight away. Similar to the GTX460's, this 670Ti will spawn the Uber, FTW, "Over the Top clocks" in small numbers with astronomical prices, but they'll get to say we bested the 7950. GTX 660 2Gb as general OC's as the volume at a wide range of price points that cover 7870/7850, while then the remains go into an SE or 192-Bit that best the 7770, although still above $230. They can spawn 4 different GK104 variations right from almost day one. The days are gone where a bunch of chips just didn't make the grade. I think Nvidia Fermi and now Kepler architecture has more production variances. Now given that TSMC price increase for 28Nm wafers killing the old value of moving to a shrink, Nvidia has no choice but spend more time sorting and binning to get the most from each wafer. Back in the old days the time (investment) it took looking at each chip verse making three sorts probably wasn’t worth the trouble, or wouldn’t generate a large enough number to bring to market. So, today more predicable variants from a wafer, cost prohibitive to just toss say 20%, and probably improve detection and speed of looking at and sorting chips has got us here. From a business standpoint it makes sense. It leads to the divide and conquer strategy straight from the get go, in the hope buyers are so confounded that they just submit and pay more as they don't want to be seen as the Fri'er. As now it will be even more befuddling for reviewers to cross check 4 different variations along with the menagerie of AIB models. Because like today, it's getting harder to find specific reviews for a particular AIB offerings. For instance Zotac has six GTX 560 models and there's only one published review I've found W!zzard’s on a AMP edition. The problem is there a couple SKU that now show weekly as “deals”, but as we all know one AIB’s version may not always the cream or value when it gets down to testing like in a "round up" of say five different AIB’s versions. It's harder to spot the lame horse(s) in the herd. Come on really they aren't about to blow this, the strategy is to confounded and befuddle with the hope that it will keep a big bunch of folks to fence sit and it's working.
