GT300: First details about clock, memory bandwidth and shader units of the Geforce GTX 380
The GT300 specifications speak for themselves: Nvidia's new flagship is said to have 512 shaders, a memory interface of 512 Bit and GDDR5 graphics memory for the first time. These values promise a real performance monster.
The first Nvidia samples are said to provide clock rates of 700 MHz (chip), 1,600 MHz (shader) and 1,100 MHz (memory). Furthermore the chip will have 512 shader units which have a similar design as the predecessors.
Hardware-info.com estimates the processing power of the new cards to unbelievable 2,457 Gigaflops. The classical SIMD units will not be used anymore but MIMD-like units which are said to work more flexible and more efficient - the pure quantitative comparison with the G200 shows that the G300 provides a power enhancement of 163 percent.
The memory bandwidth can be estimated as well now. With a real clock of 1,100 MHz (GDDR5) and a 512 Bit connection the G300 cards should provide a bandwidth of 281.6 GiByte per second - a GTX 280 only had 140.8 GiByte. Nvidia has not revealed whether the cards will have 1 or 2 GiByte RAM - we assume there will be several versions as usual.
Exact details about the TMU and ROP units are still unknown. We look forward to Nvidia's new flagship and we will certainly keep you up to date - the new card will probably be called GTX 380.
