GF106: Nvidia Revisits The Mainstream
Enthusiasts have a love/hate relationship with Nvidia’s mainstream efforts. On one hand, the company’s G92 graphics processor, launched nearly three years ago (I know, can you believe it has been that long?) and served up killer performance for roughly $200. It was a true staple. On the other hand, G92 was the best Nvidia could do for nearly three years, and it lasted right up until…well, now. There really was no GT200-based solution capable of displacing G92 at its price point.
Sure, the manufacturing technology shrunk a bit (from 65 nm to 55 nm) and G92’s prices dropped over time to accommodate GeForce GTX 260. But we saw the same piece of silicon go from GeForce 8800 GT to several flavors of GeForce 9-series, to GeForce GTS 250. Hell, Nvidia even tried to convince us that G92 could pass as a mobile GeForce GTX 285M. Tsk, tsk.
At long last, Nvidia is sending G92 to the glue factory, replacing it with the GF106 on the company’s new GeForce GTS 450. The most distinguished addition, previously unavailable from Nvidia’s entry-level portfolio, is of course DirectX 11 support. High-definition Blu-ray audio can be bitstreamed over HDMI using GTS 450, and Blu-ray 3D video is supported, too.
GF106 is a 1.17 billion transistor chip manufactured on TSMC’s 40 nm process. As it sits on the GeForce GTS 450, Nvidia clocks the GPU’s fixed-function logic at 783 MHz. The CUDA cores run at 1566 MHz. And the 1 GB GDDR5 frame buffer is set to a 902 MHz clock rate, which turns into a 3608 MT/s data rate.

Meet The GeForce GTS 450
Perhaps you were expecting a graphics card smaller than the GeForce GTX 460? After all, this model’s GPU is one-half as complex with an aggregate memory bus one-half of the width. But the GeForce GTS 450 actually looks exactly like the GTX 460. The reference card, at least, is 8.5” long and it sports the same ultra-quiet 75 mm fan. No doubt, third-party vendors will be just as creative with their cooling solutions—and we already have a roundup of GeForce GTS 450 cards in the works, similar to our recent GeForce GTX 460 1 GB roundup.
As with the GeForce GTX 460 (and all of Nvidia’s other Fermi-based cards thus far), the GTS 450 sports a pair of dual-link DVI outputs and a somewhat inconvenient mini-HDMI connector. GF106 is like all of the other Fermi parts in that it only includes two independent display pipelines, and can consequently only utilize two of those outputs at a time.
A significantly less complex GPU translates to more modest power requirements. Nvidia suggests pairing the GTS 450 up to a 400 W PSU. The 1 GB card’s max board TDP is rated at 106 W, though we already know from experience that AMD and Nvidia rate their cards differently. Despite the lower power needs (and single 6-pin PCI Express auxiliary connector), we’re still dealing with a dual-slot form factor.
One SLI connector at the top of the GeForce GTS 450 makes it clear that two-way configurations are supported, but you can’t scale out to three or four cards as you might with a GTX 480 or 470.
