VP de NVidia : les graphismes sur console ne peuvent plus ĂȘtre meilleurs que sur PC
NVIDIAâs Senior Vice President of Content and Technology, Tony Tamasi, believes that it has become impossible for consoles to offer better graphics quality than PC; not even at launch.
âItâs no longer possible for a console to be a better or more capable graphics platform than the PC,â he told Australiaâs PC Power Play. âIâll tell you why. In the past, certainly with the first PlayStation and PS2, in that era there werenât really good graphics on the PC. Around the time of the PS2 is when 3D really started coming to the PC, but before that time 3D was the domain of Silicon Graphics and other 3D workstations. Sony, Sega or Nintendo could invest in bringing 3D graphics to a consumer platform. In fact, the PS2 was faster than a PC.â
âBy the time of the Xbox 360 and PS3, the consoles were on par with the PC. If you look inside those boxes, theyâre both powered by graphics technology by AMD or NVIDIA, because by that time all the graphics innovation was being done by PC graphics companies. NVIDIA spends 1.5 billion US dollars per year on research and development in graphics, every year, and in the course of a consoleâs lifecycle weâll spend over 10 billion dollars into graphics research. Sony and Microsoft simply canât afford to spend that kind of money. They just donât have the investment capacity to match the PC guys; we can do it thanks to economy of scale, as we sell hundreds of millions of chips, year after year.â
âThe second factor is that everything is limited by power these days. If you want to go faster, you need a more efficient design or a bigger power supply. The laws of physics dictate that the amount of performance youâre going to get from graphics is a function of the efficiency of the architecture, and how much power budget youâre willing to give it. The most efficient architectures are from NVIDIA and AMD, and youâre not going to get anything that is significantly more power efficient in a console, as itâs using the same core technology. Yet the consoles have power budgets of only 200 or 300 Watts, so they can put them in the living room, using small fans for cooling, yet run quietly and cool. And thatâs always going to be less capable than a PC, where we spend 250W just on the GPU. Thereâs no way a 200W Xbox is going to be beat a 1000W PC.â
