Am heutigen Donnerstag schlägt NVIDIA erneut den Gong zu einer weiteren Runde. Der GeForce GTX 780 folgt nur eine Woche später die GeForce GTX 770. Diese soll die Nachfolge der GTX 680 antreten und stellt die zweite GPU der GTX-700-Serie des Herstellers dar. Was sich hinter der neuen Grafikkarte verbirgt und wie diese sich in der Praxis schlägt, wird unser heutiger Testartikel darlegen.
Last week we saw the release of NVIDIA's latest graphics range - namely the 700 series and its top model, the GTX 780. In many respects the GTX 780 brings a whole new level of performance to a greater audience and as I showed, there is only a small difference between the 780 and Titan on a single screen.
Working through the new 700 series line-up, NVIDIA are now lifting the lid on their next card, the GTX 770. Like the GTX 780, the GTX 770 has had many rumours surrounding its release and like the 780, these are all related to specifications, performance and most of all the GK104 core and a GTX 680. Like the GTX 780 I first of all want to put one of these rumours to rest and state the reason why. The one that I am referring to is the speculation that GTX680 owners would be able to turn their card into a GTX 770 through a BIOS update. Simply put this CANNOT be done. Whilst both cards share the same GK104 GPU core, there are a number of factors that lead to this impossibility. Like the 780 to Titan comparison, the GTX 770 has a slightly different revision of the GK104 core with varying number s of CUDA cores and texture units, however the most significant factor for the inability to 'convert' the GTX680 lies with the on-board memory.
One of NVIDIA's major shouting points with the GTX770 is the inclusion of memory that runs at a whopping 7Gbps at stock, these are no overclocked ICs either, they are entirely new, so unless you have the ability to unsolder and resolder the ICs on to a GTX 680 as well as change the PCB layout slightly, there is no possibility of changing your card from one to the other.
With the release of the GTX 770 and the recent launch of the GTX 780, NVIDIA made on fundamental change to their cards over the GTX 690 and Titan. This change is one that may seem simple, but it is one that has a major role in the graphics market and for each of NVIDIA's partners. This change is the grant to change the PCB layout and most importantly the cooling on the cards. When the GTX Titan was released, NVIDIA put a halt on any non reference designs and in effect the only alteration partners could make was to put a sticker with their name on the card.
The is not the case with the 700 series however, whilst the GTX 770 and GTX 780 used the exact same cooler as seen on Titan, manufacturers are now allowed to deviate from the reference design and put their own mark on their cards to set them apart from the competition. In Gigabyte's case, the cooler of choice is WindForce and for a number of years now this has been at the forefront of their marketing campaigns.
With the release of the 770, Gigabyte are keen to show off the latest revision of their well known cooler, which now features a metal housing rather than the older plastic design. On top of this, Gigabyte have given the GK104 core the overclock treatment to take the 770 to the next level and let it stretch its legs a bit more.
When it comes to looking at this card, there is little more than the card in a box to look at as this is a review sample, meaning that Gigabyte have omitted the usual gubbins and accessories that we would normally see as part of a graphics card bundle.
Als der US-amerikanische Grafikspezialist AMD im Dezember 2011 die Radeon HD 7970 präsentierte, hatte das Unternehmen seit der Radeon X1950 XTX endlich wieder eine echte High-End-Grafikkarte im Sortiment. Nvidia veröffentlichte den direkten Gegenspieler, namentlich Geforce GTX 680, erst im darauffolgenden März, weswegen der Tahiti-Spross drei Monate ungefährdet an der Spitze der ...
With the coming of the GTX Titan derivation named GTX 780, we have very good performances available at a lower price point. Gigabyte is one of the companies which offer a highly overclocked variant and a custom, compact cooling system which is enough silent when the card is placed in a well ventilated computer case.
We haven't been impressed by an add-in board partners card in some time, but that quickly changed after we spent some time with the EVGA GeForce GTX 780 Superclocked with ACX Cooling video card (part number 03G-P4-2784-KR). What you get for an extra $10 over the cost of the NVIDIA GeForce GTX 780 reference design is downright amazing. You get a video card that performs right around 9% faster than the NVIDIA GeForce GTX 780 with stock speeds and is faster than NVIDIA GeForce GTX Titan video card more often than not...
The Inno3D iChill GeForce GTX 660 is an excellent graphics card. Due to the high clock frequencies it's one of the fastest GeForce GTX 660s we've tested, and the three-slot cooler keeps temperatures down which leaves overclocking potential. And in addition to cooling better than the competition, it's also very silent.
Today we are looking at a new video card from ASUS – The GTX 670 Direct CU Mini. This is a compact graphics card that should be powerful enough to play the latest Direct X 11 games on a 1080p monitor. This cute little card only measures 170mm and requires a single power connector. We will find out how it handles and whether it is worth the considerable asking price.
Nach dem Referenzdesign testen wir mit der Gainward GeForce GTX 770 Phantom gleich ein weiteres Modell aus der GeForce 700 Serie. Der Lüfter dieser Karte kann mit einem besonderen Feature auftrumpfen. Verstaubte Lüfter sind hier kein Problem mehr!
The EVGA GeForce GTX 770 of course is based on the same GK-104 graphics processor and packs in 1536 CUDA cores, 32 ROPs, 128 Texture units and has a 2GB frame buffer that runs on a 256-bit bus. The EVGA model though runs both the memory and GPU engines at higher frequencies and it also utilizes, EVGA's latest thermal design; the EVGA ACX Cooler. This cooler uses a double ball bearing design that redefines traditional enthusiast coolers. Starting with a 40% increase in heatsink volume, the EVGA ACX is more efficient at dissipating heat, allowing for 15% lower GPU temperatures. A reinforcement baseplate maintains a straight PCB, and helps lower MOSFET temperatures by 7% and memory temperatures by 15%.
