Baisse pour les Radeon 7850, 7870 et 7950


AMD vient d'annoncer une nouvelle baisse des prix pour une partie de ses cartes graphiques Radeon HD 7000.

Lancée à 449$ fin janvier, la Radeon HD 7950 était passée à 399$ en avril et 349$ en juillet. La carte perd encore 30$ pour atteindre les 319$.

La Radeon HD 7870 avait fait son apparition en mars au tarif de 349$ avant de passer à 299$ en juillet. Elle baisse de nouveau de 50$ pour atteindre 249$.

Enfin la Radeon HD 7850, lancée à 249$, passe à 209$ en version 2 Go et 189$ en version 1 Go.

Compte tenu du taux de change et de la TVA, ces nouveaux tarifs correspondent à environ 310, 240, 205 et 185 € pour les Radeon HD 7950, 7870, 7850 2 Go et 7850 1 Go. Les modèles Sapphire sont même déjà trouvables pour un peu moins cher : 299 € pour la 7950, 229 € pour la 7870 et 189 € pour la 7850.

Nvidia GeForce GTX 650 Ti, Asus DirectCU II TOP et MSI Power Edition en test

Avec la GeForce GTX 650 Ti, Nvidia finalise la famille GeForce 600 Kepler et a pour ambition claire de s'attaquer, enfin, à la Radeon HD 7770. Cette nouvelle référence milieu de gamme va cependant avoir fort à faire, AMD ayant progressivement repositionné la Radeon HD 7850 1 Go dans les parages…

La Radeon HD 7770 dans le viseur…
Si la famille Kepler a permis à Nvidia de rattraper AMD au niveau du rendement énergétique et d'opposer une concurrence féroce dans le haut de gamme, sa déclinaison vers le bas se fait avec plus de difficultés. En cause ? Une architecture au coût supérieur qui, à taille de puce équivalente, ne permet pas à Kepler de lutter à armes égales avec l'architecture GCN d'AMD.

Les GPU Pitcairn et Cape Verde d'AMD ont ainsi l'avantage en termes de performances sur les GPU GK106 et GK107 de Nvidia. Certes, l'aspect physique des GPU ne dicte pas directement leur positionnement commercial, mais compte tenu des coûts de production en hausse sur le 28nm, un tel avantage donne à AMD plus de marge de manœuvre pour pouvoir proposer un rapport performances / prix plus élevé.

Nous l'avons vu récemment avec la GeForce GTX 650, équipée du GK107, qui se contente de proposer les performances d'une Radeon HD 7750, mais pour le prix d'une Radeon HD 7770. Pour attaquer cette dernière avec la GeForce GTX 650 Ti, Nvidia doit avoir recours au GPU supérieur, le GK106, dans une version bridée. Son bus mémoire passe de 192 à 128 bits et un des 5 blocs d'unités de calcul (SMX) est désactivé. Vous pourrez retrouver plus de détails sur ce GPU dans le dossier que nous avons consacré à la GeForce GTX 660.

Une configuration qui laisse facilement penser que la Radeon HD 7770 sera effectivement battue… mais à quel prix ? Comptez 150€ voire 140€ pour la GeForce GTX 650 Ti, contre 120€ pour la Radeon HD 7770. Un positionnement qui s'annonçait relativement efficace : AMD a laissé un trou énorme dans sa gamme entre cette dernière et la Radeon HD 7850, et Nvidia profite d'un avantage en terme d'image qui ne l'oblige pas à faire la course au rapport performances/prix. 


… mais la Radeon HD 7850 est en embuscade !
Malheureusement pour Nvidia, qui va finir par s'arracher les cheveux, AMD manie plutôt bien le levier tarifaire pour ne relâcher la pression sur aucun segment. Depuis quelques temps, une Radeon HD 7850 1 Go est en train de s'approcher de ce segment et AMD a bien entendu profité de l'arrivée de la GeForce GTX 650 Ti pour finaliser ce nouveau positionnement. 

Introduite il y a 6 mois à 210€ en version 2 Go, la Radeon HD 7850 est aujourd'hui disponible en version 1 Go pour 150€ chez les plus gros revendeurs, avec qui plus est un bundle sympathique qui reprend Sleeping Dogs ou DiRT Showdown, voire les deux ! Laissera-t-elle une chance à la GeForce GTX 650 Ti ?

Al Gore has thrived as green-tech investor


Before a rapt audience, Al Gore flashed slides on a giant screen bearing the logos of 11 clean energy companies he predicted could help slow climate change.
“We can’t wait. . . . We have a planetary emergency,” the former vice president told industry leaders and scientists at the 2008 conference. “Here are just a few of the investments that I personally think make sense.
Today, several of those clean tech firms are thriving, including a solar energy start-up and a Spanish utility company that has dotted rural America with hundreds of wind turbines.
Al Gore is thriving, too.
The man who was within sight of the presidency 12 years ago has transformed himself, becoming perhaps the world’s most renowned crusader on climate change and a highly successful green-tech investor.
Just before leaving public office in 2001, Gore reported assets of less than $2 million; today, his wealth is estimated at $100 million.
Gore charted this path by returning to his longtime passion — clean energy. He benefited from a powerful resume and a constellation of friends in the investment world and in Washington. And four years ago, his portfolio aligned smoothly with the agenda of an incoming administration and its plan to spend billions in stimulus funds on alternative energy.
The recovering politician was pushing the right cause at the perfect time.
Fourteen green-tech firms in which Gore invested received or directly benefited from more than $2.5 billion in loans, grants and tax breaks, part of President Obama’s historic push to seed a U.S. renewable-energy industry with public money.
Over the course of his metamorphosis, Gore became an environmentalist hero with release of his award-winning film and book warning of carbon emissions dangerously overheating the planet. He founded an investment firm devoted in part to backing green-minded companies and later partnered with a leading venture capital firm to invest in clean energy start-ups.
“We have work to do!” Gore recently exhorted an audience while showing his trademark slide show about melting polar ice caps and the urgent need to stop burning so much oil and gas.
That declaration, his friends say, captures his obsession — he’s unable to rest in his self-appointed mission to save the planet.
“Maybe there’s someone as knowledgeable and passionate about climate change. I just haven’t met that person,” said Orin Kramer, a leading New York hedge fund manager, friend of Gore and top Democratic campaign bundler. “His schedule is intensely busy, and my sense is he lives a life that profoundly reflects his values and passions.”
In building his new career, Gore’s name has become ensnared in a broader criticism from Republicans, who put him among political allies they say the Obama administration has unjustly enriched with stimulus and clean-energy funding.
In last week’s presidential debate, Romney criticized the $90 billion that went to promote green technology, saying a number of businesses owned by Obama campaign contributors were winners.
