While AMD have been working hard behind the scenes on their next generation of graphics cards Nvidia have been running amok in the mid to high performance gaming sector. Today we look at three custom cooled solutions from Palit – their GTX760, GTX770 and GTX780 Jetstream Editions.
We have been hard at work for the last week reviewing many new 7000 series cards from AMD’s leading partners. In this review today we are looking at the new Sapphire HD7850 Overclock Edition which features a custom cooling solution and out of the box clock speed enhancements.
When we moved away from the single GPU performance via the XFX HD 7770 Black Edition S Super Overclocked 1GB and checked out the CrossFire performance via Sapphire we saw a bit of light at the end of the tunnel thanks to some awesome CrossFire scaling. The issue continued to be the price of the setup, though.
With some strong overclocks out of the box, we wonder what kind of overclocking potential we have with the model. Today we'll be finding that out exactly via the help of the MSI Radeon HD 7770 1GB OC Edition video card. There are of course a few things we need to do before we cover the overclocking side of things.
AMD’s HD 7790 graphics emerged on the scene roughly at the same time as Nvidia’s GTX 650 Ti Boost graphics card. The AMD HD 7790 was released to fill that rather large performance void left between the HD 7850 and HD 7770 using a specially designed GPU called Bonaire. The Gigabyte graphics card that we have here today represents the HD 7790 pushed to the best it can offer. We have Gigabyte’s 2GB variant of the HD 7790 with the WindForce cooling solution and a factory overclock, more specifically we have the GV-R7790OC-2GB Revision 1.1 graphics card.
We say its the “best that the HD 7790 can offer” because Gigabyte have maxed out supported GDDR5 memory by adding 2GB and they have put a rather beefy dual 100mm fan WindForce cooling solution on it. Furthermore, Gigabyte have taken the stock clock of 1GHz and raised that by 7.5% to 1075MHz. The 2GB of GDDR5 over the 128bit interface runs at the default 6GHz effective memory speed, so no overclocking there. Despite the overclock Gigabyte have recommended just a 450W power supply as a minimum for this unit while AMD recommends 500W.
In terms of features this card packs most of AMD’s high end features such as Direct X 11.1 support, GCN architecture, AMD Eyefinity support (up to six displays supported), AMD App Acceleration, AMD HD3D technology, AMD CrossFire (max 2 way), AMD PowerPlay, AMD PowerTune and AMD ZeroCore. The main stand-out features are Eyefinity and HD3D support on such a budget GPU.
We have a look at the latest HAWK video card from MSI which is driven by the NVIDIA GEFORCE GTX 660 GPU.
Since Nvidia's GTX 780 hit the market we've only had the opportunity to take a look at the reference design card which we reviewed over 5 months ago, be sure to check that review out here, but today we've kindly been provided with a custom cooled partner design of the GTX 780 that we've been greatly looking forward to. What we have is the best Gigabyte has to offer in the form of the GTX 780 WindForce OC graphics card.
This enthusiast graphics card uses Gigabyte's premium WindForce 450 cooling solution that has a trio of 80mm fans, five copper heat pipes and a hefty chunk of aluminium heatsink fins to offer cooling capabilities up to 450 watts which more than exceeds the 250W TDP of the GTX 780 GPU. That said Gigabyte have fully exploited the cooling capabilities and cranked the GPU up to 954MHz/1006MHz from the stock 863MHz/900MHz while leaving the memory untouched at the stock 6GHz effective throughput speed.
Darf's auch die Hälfte sein? Jeder, der sich den eigenen PC selbst zusammenstellt, steht bei der Auswahl des Mainboards vor der Frage: Soll ich zum teureren Mainboard greifen, das zwei vollwertige (mechanisch wie elektrisch) PCI-E 2.0 x16 Slots bietet oder ist der Vorteil gegenüber dem x8/x8-Modus des günstigeren zu gering? Dieser Frage wollen wir exemplarisch auf den Grund gehen und haben dazu zwei MSI Radeon HD 5770 HAWK im CrossFireX-Verbund auf einem ASUS Maximus IV Extreme durch unseren Benchmarkparcour getrieben und zum Vergleich auch eine einzelne zum einen mit der vollen Anbindung und das andere Mal mit nur der Hälfte der Lanes getestet.
Video cards are a bit few and far between these days and I'm not 100% sure it's going to pick up anytime soon. I suppose it's going to come down to AMD. If they release part of the HD 7000 series before XMAS, no doubt December will be busy, but if they don't, it's going to be a busy 2012 as we should see new cards from both NVIDIA and AMD.
Sapphire are readying their 7870 cards and first out of the gate is their custom design OverClock Edition. We have one on our test bench today and here is a gallery which shows what Sapphire are offering.
Eine weitere Grafikkarte aus der HD5000 Serie, die wir euch vorstellen wollen, ist die XFX Radeon HD5850 Black Edition. Diese ist mit einem höheren Takt ausgestattet und basiert auf dem AMD Referenz Design. Was uns der höhere Takt bringt, zeigen wir in unserem Bericht…
