We got word late yesterday by a friend at NVIDIA that Best Buy had slipped up and released NVIDIA branded graphics cards on Sunday night. This is the first time that we have seen NVIDIA branded video cards being sold direct and we went to a few Best Buy stores in St. Louis and sure enough, we spotted the cards sitting on store shelves. We couldn't leave the store empty handed, so we bought the card for $299.99 and headed back to see what it was all about.
NVIDIAs neue High-End Grafikkarte GeForce GTX 480 liegt von den ersten NVIDIA Partnern im Handel. Allerdings Stückweise und fast schon an einer Hand abzählbar. Wir stellen das aktuelle Flaggschiff im Referenzdesign von Zotac in diversen Benchmarks der Konkurrenz gegenüber und werfen ein besonderes Augenmerk auf die reale Leistungsaufnahme und der gebotenen Lautstärke. Wer von dieser Grafikkarte profitiert und wer sich das Geld lieber sparen sollte, steht im nachfolgenden Testbericht.
Today we take a look at how to set up a 3D Vision Surround system and then run it through a selection of real world gaming tests to find out the performance level we can achieve on the latest driver.<br /><br />We will include a full selection of 5760x1080 screenshots, 5760x1080 gameplay videos and all of this running on three Asus VG236H screens with Zotac's GTX 480 AMP! Edition in SLI.
Back in May (2012) NVIDIA released their $400 GeForce GTX 670 video card, securing the number two position in their single-GPU product stack. Just three short months later, the GeForce GTX 660 Ti graphics card arrived to market and filled store shelves at the $300 price point. With a substantial $100 price difference between these two product, consumers might (incorrectly) presume there's a significant difference in hardware or performance. To the surprise of many, the GeForce GTX 670 and GTX 660 Ti are nearly the same card. Both feature identical 28nm NVIDIA 'Kepler' GK104 graphics processors, complete with 1344 CUDA cores all clocked to identical 915 MHz core and 980 Boost speeds. Additionally, the GTX 670 and GTX 660 Ti also feature the exact same 2GB GDDR5 video memory buffer, clocked to 1502 MHz on both cards. The only physical difference between these two products resides in the memory subsystem: GeForce GTX 670 receives four 64-bit contro! llers (256-bit total bandwidth) while GeForce GTX 660 Ti is designed with three memory controllers (192-bit bandwidth). So does this amount to any real differences in video game performance?
Unlike most performance motherboards that by default carry only an x8 / x8 setup when SLI or CrossFire X is used, the ASUS Maximus IV Extreme offers us the NF200 chip to add more PCI-E lanes to the board. Over the last few years we've seen companies implement the chip to boards to help move the default SLI or CrossFire X setup from x8 / x8 which is offered via the Intel chipset, to x16 / x16 via the NF200 chip.
NVIDIA vient de lever le NDA sur sa GeForce GTX 680, qui exploite sa nouvelle architecture Kepler. Pensée pour reprendre la couronne du meilleur GPU, celle-ci est disponible dès aujourd'hui chez les revendeurs, aux alentours de 500 €.
Wie wir in Erfahrung bringen konnten, setzt nVidia bei der Kepler-Architektur anscheinend nicht mehr auf das mit dem G80-Chip eingeführte Prinzip der Hotclocks, wo also die Shader-Einheiten mit dem doppelten Chiptakt laufen. Dies macht es wahrscheinlich, daß nVidia bei der Kepler-Architektur mit deutlich mehr Shader-Einheiten ankommt als bisher erwartet worden war.
Speziell für den GK104 Performance-Chip gilt, daß es damit drei vorliegende seriöse Informationen zu diesem gibt:
- keine Hotclocks mehr
- Taktziel klar über 1 GHz
- Rechenleistung weit über 2 TFlops
Davon ausgehend kann man gut und gerne darüber spekulieren, daß der GK104 demzufolge rund 1000 Shader-Einheiten tragen müsste - damit wären die genannten 2 TFlops Rechenleistung jedenfalls erreichbar. Der HighEnd-Chip GK100 sollte basierend auf dieser Prognose dann sogar rund 1500 Shader-Einheiten besitzen. Sicher ist dies natürlich zum derzeitigen Stand noch lange nicht.
AMD have been taking all the headlines in the last month, releasing a slew of graphics cards – including the class leading (but noisy) R9 290 and R9 290X. The R9 290X managed to take the performance crown from Nvidia’s GTX 780 and GTX Titan in the ultra high end at both 1600p and Ultra HD 4K resolutions. Nvidia have been hard at work behind the scenes however and today they release their new GTX780 Ti. The big question we need to answer … is it enough to push the formidable R9 290X into second place?
As you know, KitGuru has big love for the inventor of the original 3D card and all they have done for the world. However, nVidia is about to engage in a real ‘take your balls in your hands’ exercise as it phases out the GTX460 in favour of the brand new GTX560. KitGuru look at the nature of the risk and reveals some more details in the process.
Pricing a graphics card is a fine art. Too low and you lose profit. Too high and you wind up with a warehouse full of kit no guru wants. So what price has nVidia chosen for the GTX465? KitGuru investigates.
