Sapphire Radeon HD 5870 TOXIC 2GB review
We've often opined that AMD's current high-end graphics boards would benefit from 2GB of graphics memory, but is this the case? The release of overclocked 2GB sporting Radeon HD 5850 and 5870 boards from Sapphire should help to answer this question for us, and HEXUS have taken a look at the latter of these two cards.
With GeForce GTX 470/480 firmly in mind, Sapphire receives the best GPUs and runs this TOXIC model at a core speed of 925MHz and 2GBs of GDDR5 memory at 5,000MHz, compared with the regular Vapor-X's 870MHz/5,200MHz and reference's 850MHz/4,800MHz.
Slapping an extra 1GB of GDDR5 memory and guaranteeing a higher-performing core will do nothing for the value metric. We don't suppose Sapphire will sell many, or that they will come in at much under £400, yet the point here is to make the right kind of noises.
The Radeon HD 5970 GPU is already outfitted with a 2GB buffer, of course, but the difference here is that the GPU has exclusive access to the entire amount at all times.

Unigine Heaven 2.0 benchmark released
Just in time for the GeForce GTX 400 series launch comes a new iteration of the DirectX 11 Unigine Heaven benchmark, complete with additional tessellation options to put NVIDIA's latest graphics boards through their paces given their supposed advantages in this discipline.
Unigine Corporation today announced the second version of its DirectX 11 benchmark Heaven that is based on its proprietary Unigine engine. The company has already made a name among the overclockers and gaming enthusiasts for uncovering the realm of true GPU capabilities with previously released Sanctuary and Tropics demos. Their benchmarking capabilities are coupled with striking visual integrity of the refined graphic art.
Changes:
• More tessellation load.
• Optimized engine.
• Added several new art assets.
• Introduced "extreme" tessellation mode.
