ATI and Nvidia Announce New Chips
Yesterday both Nvidia and AMD ATI announced new high-end mobile graphics solutions. ATI launched what is the world's first 40nm GPUs: the ATI Mobility Radeon HD 4860 and ATI Mobility Radeon HD 4830. Both GPUs support DirectX 10.1 games and HD content as well as being energy efficient for increased battery life. The HD 4860 mobile GPU supports GDDR5 RAM with almost twice the performance of GDDR3 RAM. AMD says that by utilizing the 40nm technology it can build the GPU in a smaller ASIC die size, which in turn allows the discrete GPU to be used in smaller notebooks. NVIDIA also announced a set of new mobile GPUs: the GTX 280M, GTX 260M, GTS 160M and GTS 150M GPUs. NVIDIA claims that the GTX 280M is the world's fastest mobile GPU and offers 50% more performance than the previous generation of mobile enthusiast level GPUs. One important thing to mention; the mobile GTX series does not use the same chip as its desktop counterpart but instead uses the G92 chip used in the 9800 GTX+ desktop cards.
