Nach dem High-End kommt die Mittelklasse - AMD dreht die Regeln der Markteinführung bei Grafikkarten diesmal um. Radeon HD 7770 und 7750 sind stark abgespeckt, aber durchaus attraktiv. Einen kleinen Rekord schafft das größere Modell schon in der Standardeinstellung.

Hardware Luxx: AMD Radeon HD 7770 und 7750
Die Radeon-HD-7900-Serie ist mit den beiden Modellen Radeon HD 7970 und 7950 vorerst abgeschlossen und auch zur Radeon-HD-7800-Serie erwarten wir in naher Zukunft erste Meldungen, doch zunächst konzentriert sich AMD auf den Massenmarkt und präsentiert am heutigen Tage die AMD Radeon HD 7770 und 7750. Lange wurde darüber gerätselt, ob AMD die GCN-Architektur in alle Marktsegmente einführen oder ein weiteres Rebranding vornehmen wird. Nun ist klar, von der kleinsten Einsteiger-Karte bis hin zum High-End-Modell setzt AMD alles auf die GCN-Architektur und die 28-nm-Fertigung. Wir haben uns die beiden Referenzmodelle und auch ein erstes Retail-Modell von XFX etwas genauer angeschaut.

PC Games Hardware: Radeon HD 7770 und HD 7750: AMDs neue Effizienzwunder in der Mittelklasse?
Die Juniper-basierten Radeon-HD-5700-Karten waren so erfolgreich, dass AMD ihnen als HD-6700-Reihe gleich eine zweite Amtszeit verschafft hat und sie erst jetzt zur Ablösung bereitstehen. AMD setzt für alle Karten ab der 7700-Reihe auf die neue GCN-Architektur, über die besonders regelmäßige Leser des Hefts, aber auch der Webseite bereits ausgezeichnet informiert sind. AMD geht damit den überfälligen Schritt in Richtung Compute, kann die zusätzlichen Transistoren, welche der neue Fertigungsprozess ermöglicht, daher aber nicht einsetzen, um ausnahmslos die Spieleleistung zu steigern. Daher fallen die Anzahl der Shadereinheiten mit 640 (HD 7770) beziehungsweise 512 (HD 7750) geringer aus als noch in den Juniper-Chips der HD-5700-Karten (800/720 Shader-Einheiten auf VLIW5-Basis). Trotz gesteigerter Taktraten und des werbewirksamen Durchbrechens der Gigahertz-Schallmauer liegt die pure Rechenleistung wie auch die Bandbreite unterhalb der Vorgänger - an die potenten Barts-Chips der HD-6800-Reihe ist ein Herankommen undenkbar.

ComputerBase: AMD Radeon HD 7770 und HD 7750
Der offizielle Startschuss für das erste Southern-Island-Produkt fiel am 22. Dezember: Ab diesem Datum durfte die Presse von der Radeon HD 7970 (ComputerBase-Test) berichten, die als erste Grafikkarte mit der neuen Graphics-Core-Next-Architektur („GCN“) an den Start gegangen war. Am 31. Januar folgte dann mit etwas Verspätung die Radeon HD 7950 (ComputerBase-Test), womit das High-End-Segment erst einmal mit den nötigen Probanden besetzt ist.
Am heutigen Tag folgen nun zwei weitere Radeon-HD-7000-Produkte, wobei es sich dabei allerdings nicht auf die mit Spannung erwartete „Radeon-HD-7800“-Serie handelt. Stattdessen schickt AMD zwei Mid-Range-Modelle in Form der Radeon HD 7770 und der Radeon HD 7750 in die Händlerregale, die die Radeon HD 5770 sowie die Radeon HD 5750 beziehungsweise die baugleichen (und nur neu benannten) Radeon HD 6770 und Radeon HD 6750 ablösen werden.

HT4U: AMD Radeon HD 7770 und Radeon HD 7750 im Test
Aktuell hüpfen wir recht schnell über die "südlichen Inseln" hinweg. Southern Island ist der Codename der neuen Radeon HD-7000-Serie und die einzelnen Untergruppen dieser Grafikkartenchips sind nach Insel-Bereichen benannt. Den Start machte Tahiti in Form der Radeon-HD-7900-Serie, unterteilt in Radeon HD 7970 und Radeon HD 7950. Und in beiden Fällen landete AMD Volltreffer
Mit beiden High-End-Grafikkarten zeigte AMD eine beeindruckende Performance in Verbindung mit sehr guter Energieeffizienz. Eigentlich hätte man beim "Island-Hopping" nun die darunter gelegene, nächste Leistungstufe erwartet: Pitcairn – somit die Radeon-HD-7800-Familie – doch AMD lässt uns noch ein wenig warten und springt erst einmal beim Insel-Rundgang zu Cape Verde.

Toms Hardware: AMDs Radeon HD 7770 und 7750 im Test: Sehr effizienter Performance-Stillstand
Seit kurzem geben wir in unserer Serie Die besten Grafikkarten fürs Geld einen Überblick, welche Karten wir in den verschiedenen Performance- und Preisklassen für besonders empfehlenswert halten. Aufgrund der Marktpreise schwanken die Empfehlungen natürlich, doch hat sich gerade in der Klasse bis 150 Euro gezeigt, dass AMD mit der Radeon HD 6870, 6850 und darunter mit der HD 6670, sowie der HD 5570 recht starke Karten im Angebot hat, was das Preis-Leistungs-Verhältnis anbelangt. Die Konkurrenz ist allerdings ebenso stark in diesem heiß umkämpften Segment. Verständlich, dass AMD in diesem Bereich, der aufgrund des Preises auch für viele Käufer mit etwas geringerem Gaming-Anspruch interessant ist, auch weiterhin gut aufgestellt bleiben möchte.
Nachdem man mit der kurz vor Jahresende 2011 vorgestellten Radeon HD 7970 alias Tahiti XT und der im Januar erschienenen Radeon HD 7950 (Tahiti Pro) bereits das High-End abgedeckt hat, schaltet AMD nun zwei Gänge zurück und versucht, das Portfolio im Einsteiger- und Mittelklassebereich mit neuen Karten auszubauen. Diese Familie trägt die Bezeichnung HD 7700 und wird wie die Tahiti-Chips der Flaggschiff-Karten in 28 nm gefertigt. Außerdem nutzen die Neuvorstellungen die gleiche GCN-Architektur (Graphics Core Next), die auf GPU-Berechnungen hin optimiert worden ist, und bringen andere Boni wie eine anständige Multi-Monitor-Unterstützung und eine dedizierte Video-Encoding-Einheit mit – zumindest auf dem Papier, doch dazu später mehr.

TweakPC: AMD Radeon HD 7770 im Test
erade erst hat AMD mit der Radeon HD 7970 sein neues und teures 3D-Flagschiff und kurz danach auch die ebenso im High-End-Bereich angesiedelte Radeon HD 7950 vorgestellt, da geht es auch schon wieder weiter im für die meisten viel interessanteren und preiswerteren Mainstream-Segment.
Die Radeon HD 7770 geht an den Start und soll nun das Preisgefüge bis 200 Euro kräftig aufmischen mit neuster GCN-Architektur und natürlich all den Features, die man von den "großen" Modellen schon kennt. Natürlich mit etwas weniger Performance, dafür aber eben zu einem sehr attraktiven Preis. AMD präsentiert die Radeon HD 7700 als 1 GHz Edition, denn diese Karte ist die erste von AMD direkt für 1 GHz spezifizierte Radeon Karte. Natürlich gab es auch zuvor schon Karten mit 1 GHz, dabei handelte es sich aber um Karten, die von den AMD Partnern übertaktet wurden.
Vorgänger der Radeon HD 7770 sind die Radeon HD 5770 und 6770, die technisch weitgehend identisch waren laut AMD und Steam-Statistik zu den erfolgreichsten und meist genutzten Karten ihrer Klasse gehören. Radeon HD 5770/6770 boten Bereits eine ausgewogene Performance zu einem recht guten Preis und die HD 7770 soll es nun noch einmal deutlich besser machen.

The AMD's new Radeon HD 7770 and HD 7750 are leaner and nowhere near as mean as their HD 7970 and HD 7950 older siblings, but they do retail at a much lower price. The new cards are intended to tackle the market sweet spot previously occupied by the HD 6770 and HD 6750, meaning $100-150 USD price points.

OCC: XFX & Sapphire HD 7770 1GB Review
To summarize, both the XFX and Sapphire HD 7770 perform well under stock and overclocked conditions. I was hoping for a little more performance to be shown off under the HD 7000 series lineup, but we can't have everything. It is a jump up from the HD 6770 cards in performance, but they also cost a little bit more too. Hopefully as the 12.x Catalyst drivers progress, we will see a little more performance from the 28nm cards. Soon, we should be seeing the HD 7800 cards which should be an interesting balance between the big dog HD 7900s and these more budget-oriented HD 7000 cards.

Techspot: AMD Radeon HD 7770 & Radeon HD 7750 Review
Having covered the $549 and $449 territories in January with the Tahiti-based Radeon HD 7970 and HD 7950, AMD is bringing its latest generation GPU to mainstream brackets today. The new Radeon HD 7770 and 7750 use the same 28nm design process and Graphics Core Next (GCN) architecture as the 7000 series flagship, albeit in more affordable configurations.
The move to 28nm lets AMD squeeze 1500 million transistors into a 123mm2 die. In addition, the HD 7700 series die is 26% smaller than the HD 6770, while containing 44% more transistors. As impressive as those figures are,
gamers will be more excited to see AMD's prices: the HD 7770 is $159 -- in line with the GeForce GTX 560 -- and the HD 7750 is even cheaper at $109, combating the GTX 550 Ti.

PC Perspective: AMD Radeon HD 7770 and 7750 Cape Verde GPU Review
Cape Verde is the smallest of the Southern Islands dies and falls into the sub-$175 graphics market depending on card vendors' pricing and overclocking settings. The real question we all wanted to know is what performance levels these new cards were going to offer and if they could be the TRUE successor to popular Radeon HD 5770. While the answer will take pages and pages of details to cement into place, I can say that while an impressive card, I wasn't as excited as I had wanted to be.

Anandtech: AMD Radeon HD 7750 & Radeon HD 7770 GHz Edition Review: Evading The Price/Performance Curve
With the launch of Tahiti behind them, AMD is now firing on all cylinders to get the rest of their Southern Islands lineup out the door. Typically we'd see AMD launch their GPUs in descending order of performance, but this time AMD is taking a slight detour. Rather than following up the Tahiti based 7900 series with the Pitcairn based 7800 series, AMD is instead going straight to the bottom and launching the Cape Verde based 7700 series first.
Today AMD will be launching two cards based on the Cape Verde GPU: the Radeon HD 7750, and the Radeon HD 7770 GHz Edition. As the Juniper based 5700 series never got a proper Northern Islands successor, this is the first real update for the x700 series since the launch of the 5700 series in October of 2009. Given the success of the 5700 expectations are going to be high, and to fulfill those expectations AMD will be bringing to bear their new GCN architecture along with a full node jump with TSMC's 28nm process. But will this be enough to enable the 7700 series to replicate the success of the 5700 series? Lets find out.

Techradar: AMD Radeon HD 7750
If AMD's HD 7970 debut Southern Islands card arrived in a fancy tux heralding a bunch of world firsts (first PCIe 3.0 card, first DirectX 11.1-compatible), this HD 7750 turns up to little fanfare in a Burton polo shirt and trainers. The new Graphics Core Next's architecture has already been shown off by the HD 7970 and those 4.3 billion transistors pack quite a punch, as it turns out, trouncing the very best of last generations' GPUs by around 20-30% at mega-high res. The HD 7970 is also excruciatingly pricey though. At £440 its staggering performance and overclocking capability are out of reach to most gamers. The HD 7750 should arrive hitting the right side of £80, making it an altogether friendlier proposal, and these new-gen AMD cards boast some excellent power efficiency by shutting off all but one core when your system enters power save mode. But what's this HD 7750 missing out on to hit that price point? Does it still make high-res screens sing?

Techradar: AMD Radeon HD 7770
AMD showed its hand first in this year's GPU arms race with Nvidia... by turning it into last year's arms race. While Nvidia has kept shtum about its upcoming new 'Kepler' architecture and looks to do so until Spring, AMD stole the march and released the first of its new 7-series cards, the AMD HD 7970, a few days before Christmas 2011. That sure was odd timing, but it taught us a lot about AMD's new Southern Islands architecture, specifically the 'Tahiti' chip. It's fully PCIe 3.0-supported, uses a 28nm manufacturing process to pack more transistors onto a PCB than ever before, and apart from offering very quick DX11 game frame rates, it's a highly energy efficient beast. When your system drifts off into standby, the Tahiti card switches itself all but off too, minimising power draw.The HD 7970's whopping £440 price made all those neat features all but irrelevant to the gaming masses though, so we're putting our hopes on this HD 7770 to deliver the best bits of the new AMD architecture for a more palatable price. The 'Cape Verde' chip that this HD 7770 is built around makes full use of the new Graphics Core Next architecture like its big bro, with ZeroCore power efficiency in tow and a solid 1,000 MHz core clock. If it can offer a slice of the HD 7970's performance for this price, it's on to a winner.Architecture, technology and specificationsThe Graphics Core Next architecture is a bold move from AMD in that it represents a move away from the VLIW instruction used in 6-series cards towards a GPU-processing-friendly SIMD vector processor.
