The first thing that comes to mind was the successful launch of AMD's new DirectX 11-ready Radeon HD 5000-series. Nvidia doesn't yet have its DirectX 11 answer ready. Admittedly, though, with scant availability of AMD's high-end Radeon HD 5870 and 5850 cards, this isn't the root of Nvidia's problems. The real thorn in the company's side is the fact that AMD has proven twice now, without a doubt, the smaller, scalable GPU and GDDR5 route it took with the Radeon HD 4000- and 5000-series is a winner from a price/performance/profitability standpoint.

As a result of AMD's success selling low-cost graphic cards with modest 3D performance, Nvidia has been forced to squeeze high-end GPUs into service as sub-$100 trench fighters. Take, for example, the GeForce 9600 GSO, 9600 GT, and 9800 GT, none of which were ever originally intended for the sub-$100 market. Complex GPUs and memory buses keep costs high, power usage is usually abysmal compared to the efficient Radeon HD 4670, and performance can't quite approach the Radeon HD 4850. The newer G96 version of the GeForce 9600 GSO helped cut costs a bit with its narrower 128-bit memory interface, but the majority of sub-$100 GeForces likely remain more expensive to manufacture than their Radeon counterparts.

With Nvidia's next-generation DirectX 11 flagship 'Fermi' delayed until next year, its prospects for wowing video card buyers in the near future are looking pretty dim. We had hopes that the recently-released GeForce G 210 and GT 220 would shake things up a little. And while the combination of 40nm lithography and DirectX 10.1 support helps the GeForce GT 220 bring a fight to ATI's Radeon HD 4650, the Radeon HD 4670 remains unchallenged when it comes to price/performance and low power usage.

Unchallenged, that is, until today.

The company is now officially unveiling its GeForce GT 240, the most powerful reference card that doesn't require an auxiliary PCIe power connector. It doesn't have DirectX 11 support, but it has exactly what Nvidia needs right now in the sub-$100 category: low production costs, low power usage, and better-than-Radeon HD 4670 performance. Should it matter that ATI has a pair of entry-level DirectX 11 GPUs planned for Q1 of next year? Only if you're willing to wait. Let's see what Nvidia is offering today.
