If turns out this is true, it will pretty much go down in history as "the lamest branding move ever". At least years ago, the Ti denotation had some kind of meaning. Now, it will just be two letters added to a mid-range product.
Perhaps Nvidia thinks it should answer the return of AMD's FX product line?
About a decade ago when programmable shaders were new, NVIDIA identified its first graphics processors that used them under the GeForce 3 series and 4 series with the "Ti" marker (for example, GeForce 4 Ti 4800), to demarcate them from mainstream "MX" series, which lacked them (eg. GeForce 4 MX 440). Exactly a decade later, there are faint indications that NVIDIA is reintroducing the Ti marker. This was found out on close examination of a leaked 266.44 GeForce driver, which recognized an unreleased NVIDIA GPU as GeForce GTX 560 Ti. This baffles us. To begin with, this doesn't seem like a notebook GPU, second, we don't know of anything big in works at NVIDIA. One plausible explanation we can come up with is that NVIDIA is using "Ti" to simply make its GTX 560 SKU "look" presentable on paper, especially since the SKU may face competition from Radeon HD 6950 1 GB the moment it's released.
NVIDIA GeForce GTX 560 Ti is being introduced to restore competitiveness to NVIDIA in the sub-$270 "performance" segment, after it was depleted by AMD's introduction of the Radeon HD 6870 and Radeon HD 6850. With GTX 560 seeming imminent, AMD is preparing two new SKUs, Radeon HD 6950 1GB and HD 6970 1GB, which, coupled with cost-effective board designs, are expected to significantly drive down prices, restoring AMD's competitiveness in the crucial market segment. The GeForce GTX 560 Ti is based on new GF114 silicon, features 384 CUDA, a 256-bit GDDR5 memory interface, and core clock speeds of 820 MHz. The new SKU is slated for January 25th.
