The performance decrease that we expected to see from Titan was present, but not nearly as bad as we expected. For example in Metro: Last Light at 5760x1080 the GeForce GTX 780 was just 9% slower than the GeForce GTX Titan. At 2560x1600 and 1920x1080 screen resolutions that performance gap narrowed to just 4-6 percent, which is on the borderline of being significant. Our testing in Battlefield 3, Bioshock Infinite, Far Cry 3, Hitman: Absolution and Tomb Raider all showed similar results. Just for fun we also benchmarked the NVIDIA GeForce GTX 580 video card that came out in November 2010 and found that the NVIDIA GeForce GTX 780 nearly doubles the performance of that card. If you happen to have one of those cards and are looking for a significant performance jump before you update, you finally have a good option and it no longer costs $999...
Die Radeon HD 7870 basiert normalerweise auf der Pitcairn-XT-GPU, ist aber seit Ende des letzten Jahres ebenso mit dem Tahiti-Grafikchip in der LE-Variante erhältlich. Letzterer bringt mehr Shader-Einheiten und den Turbo-Modus mit sich. Eine ebensolche Grafikkarte, die auf die Tahiti-LE-GPU setzt, ist die HD 7870 PCS+ Myst von Powercolor. Selbige schauen wir uns in diesem Test näher an und prüfen, wo die Leistungs-Unterschiede zur konventionellen HD 7870 liegen.
Nach der GeForce GTX 780 folgt die GeForce GTX 770, die die Pate stehende GeForce GTX 680 übertrumpfen und zugleich die Radeon HD 7970 GHz Edition schlagen soll.
Suite à la sortie des GTX Titan et des GTX 780, tout le monde attendait assez logiquement la GTX 770. C’est dorénavant fait, Nvidia nous propose la GTX 770 ; il nous tarde donc de pouvoir donner un avis sur cette nouvelle venue. En effet, cette carte sacralise presque toute l’attente des utilisateurs. Elle sera proposée à un tarif plus abordable que ses aînées et représente l’évolution directe de l’ancienne GTX 680, carte qui possédait déjà des performantes très intéressantes. Toutefois, certains décrient les caractéristiques proches de la GTX 680 et en se posant des questions sur un simple rebadgage. Vous allez voir que cette GTX 770 nous réserve de belles surprises.
Vous l’avez sans doute vu précédemment, la GTX 770 de Nvidia s’avère être une carte très intéressante, avec une belle évolution de performances par rapport à une GTX 680. On est donc en droit de penser qu’une GTX 770 modifiée, nous sous-entendons par là une carte avec un refroidissement repensé, un PCB revu et un Oc d’usine, pourrait être une idée formidable.
Quel heureux hasard, nous disposons justement d’une MSI GTX 770 Lightning, qui réunit tous les critères précédemment cités. De quoi nous donner l’occasion de nous forger notre propre opinion.
Based on the GK104 GPU used on cards such as GTX 680 we have three factory overclocked versions of the GTX 770 on our test bench and all have their own custom design. We'll be putting them through a selection of real world tests against overclocked 680 and 7970 cards (as well as GTX 780) to see how they do in titles like Crysis 3, Metro: Last Light and Grid 2.
Today we look at a customised, overclocked version of the new Nvidia GTX770 graphics card from MSI. The latest GTX770 is based around the same GK104 GPU that was used in the ever popular GTX680. The GTX770 is priced close to the HD7970 and targets the high end gaming audience who don’t want to compromise their frame rate performance at high resolutions. Should this be making your shortlist for a new system upgrade?
Graphic cards
The NVIDIA GeForce GTX 770 is based on the Kepler GK104 graphics processor. The GTX 770 can be considered a rebranded GTX 680 since it uses the same processor but there have been many upgrades. The GTX 770 now comes with higher clock speeds, 7GB/s memory modules with a peak bandwidth of 224.3 GB/s, GPU Boost 2.0 and will come in two different variations, 2 or 4 GB. The 4 GB version focuses on those who crave the gaming experience of multi-monitors or ultra HD resolutions.
Though it might seem a bit unusual to see NVIDIA let loose its GTX 770 a mere week after its 780 launch, here’s something to clear things up: $399. Built on GK104 (not GK110, like the 780), the GTX 770 is in effect a beefed-up GTX 680. It boasts 700 series features, NVIDIA’s latest cooler, and of course, a savings of about $100.
Graphic cards
The Gigabyte GTX 770 OC video card uses a custom Windforce 3X cooling solution that can effectively dissipate heat off of the supercharged GK104 GTX 770 GPU core. The Gigabyte GTX 770 Windforce OC video card has six copper heatpipes and aluminum fins organized in a triangular shape to effectively minimize the flow of turbulence between the fans that results in a low noise video card performance.
