<p><span style="font-size: small;"> Throughout the lifetime of the 400 series, NVIDIA launched 4 GPUs: GF100, GF104, GF106, and GF108. Launched in that respective order, they became the GTX 480, GTX 460, GTS 450, and GT 430. One of the interesting things from the resulting products was that with the exception of the GT 430, NVIDIA launched each product with a less than fully populated GPU, shipping with different configurations of disabled shaders, ROPs, and memory controllers. NVIDIA has never fully opened up on why this is &ndash; be it for technical or competitive reasons &ndash; but ultimately GF100/GF104/GF106 never had the chance to fully spread their wings as 400 series parts.</span></p> <p><span style="font-size: small;"> It&rsquo;s the 500 series that has corrected this. Starting with the GTX 580 in November of 2010, NVIDIA has been launching GPUs built on a refined transistor design with all functional units enabled. Coupled with a hearty boost in clockspeed, the performance gains have been quite notable given that this is still on the same 40nm process with a die size effectively unchanged. Thus after GTX 560 and the GF114 GPU in January, it&rsquo;s time for the 3^rd and final of the originally scaled down Fermi GPUs to be set loose: GF106. Reincarnated as GF116, it&rsquo;s the fully enabled GPU that powers NVIDIA&rsquo;s latest card, the GeForce GTX 550 Ti.</span></p> <p><span style="font-size: small;"><a target="_blank" href="http://www.anandtech.com/show/4221/nvidias-gtx-550-ti-coming-up-short-at-150">Read more...</a><br /> </span></p>
