If you thought that MSI N580GTX Lightning was the best GTX 580 out there, there is a competitor coming in time for Computex Taipei 2011.

Zotac is readying a GeForce GTX 580 that should be able to reach the "magical" 1GHz clock for the GPU and 2GHz for the 512 cores, and theoretically beat the clocks N580GTX Lightning is capable of running at.

18-Phase VRM with best components money can buy - 2-Phases feed the 1.5GB of GDDR5 memory and massive 16 are reserved for the power-hungry GF110 GPU chip

In order to claim the best single-GPU crown, Zotac resorted to building a custom PCB (Printed Circuit Board) with no less than a complex 18-phase VRM (Voltage Regulator Module). Each of 18 phases uses top-of-the-line MOSFETs, industrial-grade capacitors and proadlizers for further conditioning of the power current. Based on PCIe 2.0 spec, the board can handle 450 Watts; 150W from PCIe x16 2.0 slot, and 300W from two 8-pin PEG power connectors.

Second part to enable extremely high clockspeeds is the multi-part heatsink. First and foremost, the cooling solution is actually consisted out of two heatsinks: a thin heatsink for GDDR5 memory and all the VRM’s and a massive dual-120mm fan, six fat-heatpipe, triple slot cooler for the GPU. If we’re not mistaking, this is the first time a 120mm fan has been used to cool down a graphics card (excluding after market passive solutions from companies such as Zalman or ThermalRight).

A Monster without disguise: Dual 120mm, Triple-slot fan promises a lot of overclocking headroomDefault clocks on the board are 850MHz for the GPU, 1.7GHz for 512 cores (+78MHz GPU / +156MHz Core, 11% beyond stock GTX580), and 1.1 GHz QDR for the memory i.e. only 98MHz faster, resulting in 206.3GB/s of video memory bandwidth.

The card is set to debut at the beginning of June on Computex Taipei 2011 for a yet unnamed price. Given Zotac’s preference to launching special editions for limited Asian markets (China, Hong Kong, Japan, South Korea, Singapore and Taiwan), we’re not exactly certain that MSI’s N580GTX Lighting is getting a competitor on a global scale.

Still, all of these air cooled cards have to battle the liquid cooled stock cards, which can easily outreach the liquid cooled parts such as ones coming from Point of View (under TGT Brand), as Asetek’s recent GPU liquid cooling testing demo proved, reaching fantastic 995MHz for the GPU and 1.99GHz 512-core clock.
