Zotac unveils superclocked GTX 460

Now that Nvidia finally has a Fermi GPU that doesn't spew out ridiculous amounts of heat, Zotac has taken the opportunity to launch an overclocked GeForce GTX 460 with a sensibly-sized cooler.

Unlike the company's GTX 480 AMP! Edition, which required a mammoth triple-slot cooler to quell the heat from the overclocked GPU, Zotac's GeForce GTX 460 AMP! Edition features a simple, dual-slot cooler custom-designed by Zotac. With a single, central fan, Zotac claims the new cooler not only reduces the temperature compared with the reference cooler, but also the noise levels.

Zotac's marketing director Carsten Berger explained that the company's engineers "spent extra time tweaking the Zotac GeForce GTX 460 AMP! Edition design to achieve the performance we desired. The result is a graphics card that pushes the limit of the GPU and memory performance capabilities without making any sacrifices to noise, temperature or packaging."

Despite only having a case-friendly dual-slot cooler, Zotac hasn't been conservative with the overclock. The GTX 460 AMP! Edition takes the GPU clock speed all the way up to 810MHz, with 1,620MHz stream processors. That's a 20 per cent increase over the GPU's stock 675MHz clock speed.

As well as this, Zotac has also overclocked the card's 1GB of GDDR5 memory to 4GHz (effective), compared with the reference clock speed of 3,600MHz (effective).

According to Zotac, its clock tweaks have transformed the GTX 460 "into a completely new animal with blistering fast performance that is unmatched by rivals." It looks as though no one's told the guys who worked on it about Point of View's GTX 460 Ultra Charged, which has a slightly higher 820MHz GPU clock speed.

Even so, a guaranteed 810MHz clock speed is going to make this a decent-performing card out of the box.

There's no word on UK pricing or availability yet, but we'd expect the card to come in at around £190, based on the price of comparable products.
