Zur Vorstellung der Grafikkarten mit AMD Tahiti-LE-GPU sah man praktisch nur drei Anbieter, welche aber alle das identische Produkt aus Tul-Produktion mit teils unterschiedlichem Lüfter präsentierten. Nun betritt AMDs großer Partner Sapphire die Bühne und stellt seine Variante als Radeon HD 7870 XT with Boost vor. Ob das Sapphire-Produkt das teils gemischte Gesamtbild von Tahiti LE besser zeichnet, verrät unser heutiger Test-Artikel.
We take a look at our second Tahiti LE based AMD Radeon HD 7870 video card and overclock it this time as well to see what's on offer.
We check out Sapphire's OC Edition variant of the new HD 7870 and see what it does for us today. Let's check it out!
We have one of the first retail 7800 cards available to us in the form of Sapphires 7850 OverClock Edition. Today we will be putting it head to head with the GTX 560 Ti Overclock in order to find out which comes out on top. Tests include Battlefield 3, Skyrim and The Old Republic along with the usual media, GPU computing and power/temperature results.
AMD’s 7000 series is made up of 3 segments. Starting with the flagship 7900 which are the high-end cards. Then we have the 7700 series which has budget gamers in mind. Finally we have the 7800 series which sits right in the middle to hit the sweet spot between cost and performance. The 7800 series has 2 cards the 7850 and the 7870, today we are taking a look at the 7850. Not just any 7850 though, the 7850 Overclocked Edition from Sapphire. This card really makes the sweet spot even sweeter with a factory overclock moving the core up to 920MHz and the memory up to 1250MHz. Sapphire has also added their popular Dual-X cooler for better cooling performance. Read on to see what this card is all about.
Graphic cards
With the 7800 series now launched, Sapphire have brought a factory overclocked edition to market, but can it keep up in this fast-paced graphics market?
We check out the pre-overclocked HD 7850 2GB from Sapphire and see how it performs today.
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...
We are looking at the brand new Radeon HD 7790 Graphics Card. It is the Sapphire Radeon HD7790 Dual-X OC with 1GB GDDR5 Memory and default overclocking. The new Radeon HD 7790 is close to the Radeon HD 7850 when it comes to performance, but let us see hot it actually perform in real life.
Nachdem wir bereits vor wenigen Tagen die XFX Radeon HD 7790 Black Edition im Test hatten, folgt mit der Sapphire Radeon HD 7790 Dual-X OC eine weitere Radeon HD 7790 basierte Grafikkarte mit Übertaktung ab Werk. Bereits vor einigen Wochen präsentierte AMD unter dem Codenamen "Bonaire" die neue Radeon HD 7790 GPU. Aufgabe des neuerlichen Grafikchips ist es, die entstandene Leistungs-Lücke zwischen Radeon HD 7770 und Radeon HD 7850 zu schließen und gleichzeitig Marktanteile in diesem Preissegment von Nvidia abzugraben. Im Bereich von etwa 100-130 Euro war bis zur Vorstellung der HD 7790 die GeForce GTX 650 Ti beinahe konkurrenzlos – dies soll sich mit Bonaire jedoch ändern! Bonaire ist dabei nicht etwa eine abgespeckte Variante von Pitcairn (Basis für Radeon HD 7800-Familie) oder ein aufgebohrter Cape Verde (Basis für Radeon HD 7700-Familie), sondern eine tatsächlich neue 28 nm GPU, basierend auf AMDs GCN-Architektur. Dadurch möchte man vor allem bei der Preisgestaltung mehr Spielraum haben und entsprechend attraktive Partner-Karten ermöglichen. Wir haben uns die Sapphire Radeon HD 7790 Dual-X OC mit 1 GB GDDR5-Speicher zum ausführlichen Test eingeladen und auf Herz und Nieren überprüft!
