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.
AMD just introduced the Radeon HD 7790 desktop graphics card that is powered by the new Bonaire GPU. This card uses the latest GCN (Graphics Core Next) architecture from AMD along with 896 Stream processor units to bring better performance to gamers at the $149 price point. Read on to see how cards from Gigabyte and Sapphire do when put to the test!
Today we are taking a look at a brand new video card from Sapphire. We have been hearing about the Radeon 7790 over the past few weeks and earlier this year AMD said we would see an HD 8000 series towards the end of the year and they would be refreshing their HD 7000 lineup with new chips. The HD 7790 is the first card that is part of this refresh, based on the brand new “Bonaire” 28nm graphics processor. The Bonaire graphics processor is based off of AMD’s graphics core next (GCN) architecture and features 896 stream processors. We are looking at Sapphire’s version, which is the HD 7790 OC with Dual-X. The Dual-X is for Sapphire’s own unique cooling system on the card. This card features a 1075MHz core clock, 1GB of GDDR5 memory and has dual DVI, HDMI and DisplayPort connections. This card is setup to compete directly with Nvidia’s GTX 650 Ti. Read on as we take a look...
Mit dem heutigen Tag startet AMD den Verkauf der AMD Radeon HD 7790 - einer neuen Grafikkarte, welche dieses Mal jedoch nicht auf einer Abwandlung eines bereits existierenden Grafikchips aufsetzt. Stattdessen verfügt die Radeon HD 7790 über eine neue GPU mit dem Codenamen Bonaire. Damit will der Hersteller die Leistungslücke zwischen Radeon HD 7770 und HD 7850 schließen und nimmt sich gleichzeitig die GeForce GTX 650 Ti zur Brust. Im heutigen Test vertritt Sapphires HD 7790 Dual-X OC den jüngsten AMD-Spross.
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.
Sapphire has created a very nice card based on the Radeon HD 7790. The higher clock frequencies (1075 MHz GPU, 1600 MHz memory) make the Sapphire Radeon HD 7790 Dual-X OC faster than a standard 7790. The cooler is both efficient and quiet.
AMD has released a new model and we see just what the Radeon HD 7790 is about with the Dual-X OC model from Sapphire.
Radeon HD 7790 im Test: AMDs brandneuer Grafikchip "Bonaire" schickt sich an, die Führung im Preissegment zwischen 100 und 150 Euro zu übernehmen - die Radeon HD 7850 mit 1 GiByte Speicher läuft aus. Ist Nvidias Geforce GTX 650 Ti geschlagen? PC Games Hardware hat sich den kompakten GCN-Refresh angesehen.
Not too long ago we heard the announcement that AMD were to bring out a new 7000 series card that would fill in a gap in their product line-up to take on NVIDIA's 650Ti GPU. This card is of course the 7790 and goes by the code name "Bonaire". Like we saw way back when the 6790 was released, the 7790 fills the void between the entry level 7770 and the midrange 7850 which is a slightly larger gap than some may think in terms of performance.
