GPU add-in-board partner Sapphire Technology has launched a new factory overclocked graphics card based on the AMD 7970 GHz Edition GPU (which we did a live video review of recently). That particular chip is built on the 28nm Graphics Core Next (GCN) architecture and brings several improvements over the initial (non GHz Edition) 7970 GPU. The main difference between the two is that the GHz variant is a higher binned part that also features a new GPU boost technology similar to NVIDIA’s dynamic overclocking function.  The new Sapphire Toxic card takes that chip and pushes it to the max with two levels of factory overclocked settings.

Packing the company’s custom dual 90mm fan and heatpipe-equipped Vapor-X cooler, the HD 7970 TOXIC Edition features 6GB of GDDR5 memory, 2,048 stream processors, and a 7970 GHz Edition GPU. Out of the box, the card has a base GPU clockspeed of 1050 MHz and a boost speed of 1100 MHz. On the memory side of things, it runs the GDDR5 at 6,000 MHz (effective). When you press a button – which the company calls the Lethal Boost Button – the base clockspeed becomes 1100 MHz and the boost speed becomes 1200 MHz. The Lethal Boost also overclocks the memory to 6400 MHz (effective).

The card also includes a 12 layer black PCB with a new eight phase power design package for the GPU and an additional power phase for the VDDCI and MVDD along with other high-end goodies to deliver the stable voltage necessary for the high factory overclocks. Rear IO on the graphics card includes two DVI ports – one dual link and one single link – one mini-DisplayPort, and one full-sized HDMI port. In all, it is a dual slot card and measures 275mm in length, and 115mm wide. You will be able to purchase the Toxic edition card for $680. It looks like a really good card, but it’s not cheap.

NVIDIA's GTX 550 Ti did not do so well when Ryan reviewed it, as it simply wasn't fast enough to justify the price is being sold at.  Now its bigger brother, the MSI GTX 560 Ti Hawk has made an appearance on the [H]ard|OCP review bench.  Sticking with their usual milieu with the Hawk series, the only original part on this MSI card is the Fermi silicon, the PCB, GDDR5 and cooler are all specifically designed and implemented for this series of card. Can the overclock match the HD6950 which costs only $20 more?

"Microstar's latest Hawk video card is here, packing a highly overclocked NVIDIA GeForce GTX 560 Ti. Can its enhanced PCB and cooler fend off the Radeon HD 6950's falling prices? Does it actually offer anything over a standard GeForce GTX 560 Ti? The end results are incredible and price drops have completely changed the landscape."
