Sapphire has announced what it claims is the world's fastest single-GPU graphics card, the Radeon HD 7970 TOXIC Edition 6GB.

As the name suggests, the board is based on AMD's Radeon HD 7970 GPU and packs a whopping 6GB of GDDR5 graphics memory - the first consumer-oriented single-GPU board to include such a large framebuffer. By default, the board runs at 1050MHz standard or 1100MHz in dynamic boost mode; press the Lethal Boost Button, however, and the board overclocks to 1100MHz standard and 1200MHz in dynamic boost mode, with the memory jumping from 6GHz effective to 6.4GHz effective.

Sapphire claims that the board is rock-solid stable at these speeds, thanks largely to a new power control system exclusively developed by the company. Dubbed the Lethal Power Suite, the package includes a new eight-phase power design for the GPU VDDC, with an additional phase each for the VDDCI and MVDD, along with double-sided Black Diamond Choke and DirectFET technology on a 12-layer PCB. The Black Diamond Choke, in particular, is key the card's overclocking potential: in testing, Sapphire claims to have reduced the power design circuitry temperature by 40 degrees Celsius compared to AMD's reference design.

To help keep things even cooler, Sapphire has redesigned its Vapor-X cooling system, modifying the vapour chamber specifically for the Radeon HD 7970 TOXIC Edition 6GB. Heat is carried away from the board through two 8mm and two 6mm heatpipes and dispersed through a large heatsink thanks to two 90mm fans with aerofoil blades and dust-repelling bearings. For even more peace of mind during overclocking beyond the 1200MHz level, the board also includes an LED which warns of high temperature levels.

If you've after an ultra-fast single-GPU board, the Sapphire Radeon HD 7970 TOXIC EDition 6GB is certainly that - but with US pricing set at $680 (around £434 excluding taxes) and UK pricing yet to be confirmed, you can expect to pay for the privilege.

Seems kinda cool, but I can't see too many people needing that amount of GDDR.
Personally, if I were in the market for a 7970, I'd save a few quid and get the 3GB.

GIGABYTE GeForce GTX 680 SOC is in same class but has 5 fans and weights 1.6 kilo

Obviously weight is the new "thing" when it comes to final decisions in comparisons of GPUs.

Nice spec's but I will stick to my GTX 680 2Gb card, as it does everything I need it to and can overclock to a high speed anyway if required.

I doubt this card will be the fastest gpu for long if it is considering what nvidia are like :D

Nice specs, but a triple slot card? No thanks.

Just what I was thinking - this is pointlessly overkill. It reminds me of back around 2005 when 1GB cards were released and nothing could take advantage of it, although back then 1GB was pretty decent for workstation graphics.

I would much rather get 2 7970 3GBs than this.

From the reviews i've seen on the reviews from kitguru, hexus and overclockersclub, it's still pretty much swings and roundabouts when up against a factory overclocked 680.

Hahahaha "lethal power suite".

Where do they get these names from?

For those of us with three 30 inchers this is a must buy, and at such a cheap price I am thinking about getting two.

Wondering what the power plugs needed are, 8+8 id guess.

Do NOT run these on a BT system with an anemic PSU!
