All'inizio di quest'anno ASUS ha presentato una NVIDIA GTX 670 davvero molto interessante dedicata principalmente ai sistemi HTPC e Small Form Factor. La scheda video in questione, denominata GTX 670 DirectCU Mini, è caratterizzata da un PCB di ridottissime dimensioni e da un dissipatore altrettanto miniaturizzato, ma comunque in grado di tenere perfettamente a bada la potenza della GPU GTX 670. Vedremo meglio nel corso della recensione cosa sarà in grado di regalarci questo concentrato di tecnologia.
Its that time of year again where NVIDIA have a new series of cards in the pipelines and as we have seen running up to today, the number of rumours and leaks that have been flying about are as profound as ever. For some this leads to pure confusion as to what is to be seen and what is complete rubbish, and for people like myself it leads to pure frustration as I know all the true facts and figures, meaning that when I see the rumours and false facts floating around I can do nothing but sit and wait until the NDA lifts to put a number of these claims to rest with the real specifications and performance figures behind the new cards.
So here we have it, the GTX 780 - the first in the new line of Kepler based 700 series cards and before we get too far into the nitty gritty of what's new in the 700 series, I want to make the following fact clear and true - the GTX 780 CANNOT be flashed in any way to effectively turn it into Titan. There are a number of reasons for this; first off, whilst both cards share the same GK110 core, the 780 has far less CUDA cores, is a different revision of the core chip and has less texture units on-board. On top of this, there is also half the amount of video memory and a number of components in the power region of the PCB are missing as the 780 does not require these as opposed to Titan.
Point out of the way, NVIDIA's new 700 series cards are here to replace the ever popular 600 series, although they are not a re-hash and re-brand of 6xx cards as some may presume. Whilst the GK110 cores may be featured on both 600 and 700 series cards, they will have subtle variances to them, mainly on the front of CUDA core count and texture filters and so forth.
So what is the 780 in relation to the 600 series cards. Whilst it may look like Titan, it is a slightly lower performing card. Titan is more geared towards users with multiple high resolution displays and thus the higher 6GB of GDDR5 memory that it encompasses. The 780 whilst still home to 3GB of GDDR5 is more aimed at users who are going to be gaming on a single screen at high resolutions with all the settings turned to 11. Over its predecessor, the GTX 680, the 780 has 50% more CUDA cores with a count of 2034, 50% more memory, up to 3GB from 2GB and overall a 34% increase in performance. Interestingly enough, GTX 580 users who upgrade to a 780 will see a whopping 70% gain in performance between the two cards and a 25-30% gain can also be found over AMD's 7970.
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.

The EVGA GTX 770 Superclocked 2GB video card is equipped with EVGA’s revolutionary new ACX cooler designed to provide quieter and superior performance. The EVGA GTX 770 SC’s ACX cooler maintains a dual-slot design for efficient thermal properties in SLI mode. The EVGA ACX cooler is equipped with 40% higher fin volume and separated cooling subsystems so the double ball bearing fans can efficiently dissipate heat emitted by the GTX 770’s GK104 core and components while under load. The EVGA GTX 770 with ACX cooler is super clocked with a base of 1111MHz and boost of 1163MHz compared to the reference 1046 MHz base clock and the 1085 MHz boost clock. As with all EVGA video cards, the GeForce GTX 770 2GB Superclocked with ACX cooler video card comes packed with EVGA Precision X and OC Scanner software for further overclocking convenience. The EVGA GTX 770 Superclocked video card is covered under EVGA’s standard 3-year warranty and further warranty extensions are available for users who register their purchase within 30 days.
The Sapphire Dual-X OC also comes with a faster than average GPU core that is overclocked to 1075MHz, and the card also features a 1GB GDDR5 frame buffer that is factory overclocked to 1600MHz
The Nvidia GeForce GTX 760 offers performance that is a notch above the previous generation GTX 670, but with a MSRP that is $100 more affordable.
Mit der GeForce GTX 760 Phantom von Gainward konnten wir noch eine dritte Version der GTX 760 testen. Wie schon bei der GTX 770 Phantom kommt auch das kleinere Modell mit entnehmbaren Lüftern daher. Alles weitere im Test.
Mehr Bilder pro Sekunde = Mehr Spielspaß. Eine einfache Formel, der so genannte „Mikroruckler“ einen Strich durch die Rechnung machen. Wir testen den Status quo bei AMD und Nvidia.
The XFX R7790 Black Edition graphics card is great product for gamers that are running 1080p displays and want a graphics card that won't break the bank. At just $139 (after discounts) the XFX R7790 BE can easily run the majority current generation games above 30FPS at 1920x1080 and even demanding titles such as Battlefield 3 run smoothly with this card. The low memory bandwidth can be an issue for next-gen games though, as titles such as Crysis 3 and Metro 2033 stutter along in the low 20FPS range.
Die Geforce GTX 770 wurde von Nvidia vor wenigen Wochen veröffentlicht und verdrängt nun langsam aber sicher die GTX 680 vom Markt. Entsprechende Varianten der Boardpartner sollen diesen Vorgang mitunter beschleunigen. So bietet beispielsweise Gigabyte mit der GV-N770OC-2GD eine potente Lösung an. Dieses Modell kann mit einer der höchsten GPU-Taktraten unter den GTX-770-Ablegern aufwarten und ist zudem mit Gigabytes performanten Windforce-3X-Kühler ausgestattet. Neben der Leistung will der Hersteller mit einem guten Preis-Leistungs-Verhältnis punkten. Ob Gigabyte am Ende ein empfehlenswertes Produkt abliefert, erfahrt ihr in diesem Test.
