Last week we had some hands on time with the latest AMD GHZ HD7970. At the end of the day it left us feeling distinctly uninspired. There was no doubt the card was fast, but AMD sadly adopted their ill equipped, painfully loud cooling solution with tiny, single red fan.
So far we've had some good success when it comes to overclocking which we looked at in our HIS HD 7970 and XFX HD 7970 Black Edition Double Dissipation review. Adding a second card into the mix is known for limiting overclocking ability as cards are placed together and more heat is generated. Those numbers are then amplified due to the added voltage being thrown through the core of each GPU.
Since we've already looked at the Sapphire HD 7970 in our original CrossFire review, we won't need to have a look at the card again. Instead we'll get straight into the testbed setup and quickly cover how we went with the overclock. Once we've done that we'll just get straight into the performance.
Mit der Radeon-HD-7000-Serie ist dem US-amerikanischen Grafikspezialisten AMD ein ganz großer Wurf gelungen. Als die Radeon HD 7970 Ende 2011 offiziell vorgestellt wurde, konnte das Unternehmen sowohl die eigene Radeon-HD-6000- als auch die gegnerische Geforce-GTX-500-Serie mit Leichtigkeit übertrumpfen. Einerseits arbeitete die neue Grafikkarte wesentlich schneller, andererseits verbrauchte ...
Today we are taking a look at Sapphire's 7950 FleX Edition. With this card, there is no need to use expensive DisplayPort monitors or adapters for Eyefinity. Add to that an upgraded cooler, overclocked core, and the raw power of a 7950, and we may just have a winner here.
Today we take our second look at Tahiti LE with the Sapphire 7870 XT (With Boost) and in this article will be maxing out its core and memory speed then checking how it performs in games like Far Cry 3, Assassins Creed 3 and Hitman Absolution against a max OC 660 Ti.
Today we will put two of the top models, Sapphires OC Edition and XFX's DD Black Edition head to head in order to find out what they offer mainstream gamers looking for top performance in the latest games...including Mass Effect 3, Battlefield 3 and Skyrim.
Today we take a look at the Sapphire 7870 FleX. This card can power 3 monitors at once, but does it have enough muscle to take them to the max?
TechwareLabs reviews the Sapphire HD 7850 OC showing a reasonably priced Radeon card with Eyefinity puts up benchmark numbers that challenge or surpass the NVIDIA 500 series. We benchmark the HD 7850 OC on a PCI 3.0 and PCI 2.0 motherboard to see if the HD 7850 OC has what it takes to take advantage of this new technology.
Designed to replace the 7850 1GB in the AMD 7000 series, so between 7770 and 7850 2GB, this new product is AMDs attempt to offer a mainstream GPU with exceptional price to performance ratio.
Graphic cards
The Sapphire Radeon HD 7790 OC edition is one of the latest GPUs based on AMD’s 28nm Graphics Core Next (GCN) architecture and uses the Bonaire GPU. The Sapphire 7790 features their custom dual-x cooling solution. The custom cooler is designed with two fans and multiple heat pipes to keep the card cool during intensive use. The GPU clock speed is factory overclocked to 1075 MHz from the standard 1GHz reference speeds. The 7790 also features AMD's newest version of their PowerTune technology, which is designed to be more power efficient and allow for higher clocks. The memory on the card is one GB of GDDR5 and features a 128-bit bus, with a memory clock speed of 6000 MHz.
