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.
The GTX 560 Ti is a killer card and at launch we saw some companies do some fantastic things with the model when it came to overclocks. This is great for you the consumer, but for AMD and its partners, not so great. The HD 6950 offers great performance, but with 2GB of GDDR5 the price of the card is higher than the GTX 560 Ti which carries with it only 1GB of GDDR5. Personally, I thought it was a mistake for AMD to push 2GB models of the card, as it means prices are higher and if the past has told us anything, it brings little gains when compared to its 1GB counterparts.
Today Sapphire becomes the first GPU manufacturer to attach 2 GB of DDR5 to a Radeon 4870 making it one of the most impressive models available in terms of paper specifications. They haven’t stopped there however as the card also features their own PCB design and a cooler based on the Vapor-X technology which we have seen on a few of their previous cards.
The NVIDIA GeForce GTX 470 might not be the coolest running graphics accelerator around, but that doesn't stop overclockers from attempting voltage modifications on it. Guide inside.
S'il est une carte qui est bien sortie du lot parmi tous les modèles DX11 de première génération du caméléon, c'est bien la GTX 460. En effet, là où ses grandes soeurs pêchaient par excès de tarification, consommation, températures et nuisances sonores face à la concurrence, cette dernière s'avérait au contraire parfaitement calibrée dans ces domaines tout en devançant nettement sa rivale directe ! Il a fallu attendre l'avènement de la seconde génération DX11 d'AMD via Barts pour lui trouver une rivale digne de ce nom (HD 6850). Le caméléon a depuis répliqué en débridant totalement sa puce miracle moyen de gamme (GF104) via une nouvell e révision (GF114), étrennée par la GTX 560 Ti dont le suffixe laissait supposer un modèle moins performant à venir. C'est le cas avec la GTX 560 qui reprend la dernière révision du GPU avec une amputation similaire à la GTX 460, mais des fréquences en nette hausse, verdict ?
In this review, we will be looking at a new gpu from nvidia which is targeted directly at the mainstream gamer. When we define "mainstream gamer," we are talking about the type of gamer who isn't sitting on a pile of money, the type of gamer who embraces overclocking to extend the life of their system, the type of gamer that might be you.
Nei giorni scorsi con grande sorpresa AMD ha presentato una nuova scheda grafica discreta dedicata alla fascia mainstream del mercato ludico. Questa scheda a dispetto di quello che ci si poteva aspettare non è un refresh o una versione più ridotta delle sorelle maggiori, ma equipaggia un chip grafico tutto nuovo. Bonaire è il chip che dà il nome alla Radeon HD 7790, una scheda nata per colmare prezzo e prestazioni della fascia che va dai 100$ ai 150$.
HTPCs and HD content are growing more and more around the GPU industry. ATI and NVIDIA have been working on technologies to playback and enhance this video content for many years. NVIDIA started working on their Purevideo technology and added the Purevideo HD some time ago. ATI on the other hand, has their own AVIVO technology and as it was obvious, they name their latest technology AVIVO HD.
KitGuru is old in the tooth and likes naming conventions which don't change. With the launch of the Radeon HD 6000 series, AMD has altered its naming strategy. The high end cards will now be the 6900 series (due November) and the 6800 cards that we're looking at today, will actually be sold for less than £200 each, including VAT (we're guessing that's under $250 for our American readers). How much can any gamer get from a graphic card that costs so little?
The PowerColor Radeon HD 7850 SCS3 1GB video card is without a doubt an impressive looking card. You don't run across passive cards every day, let alone a mid-range AMD Radeon HD 7850 1GB card with the reference clock speeds left intact! PowerColor was very ambitious with this cards design, but did they hit a home run or a foul ball?
