Czech technology website PCTuning confirmed a few details about NVIDIA's upcoming performance graphics accelerator, the GeForce GTX 470. It was found out that a beta driver by NVIDIA, GeForce 196.78 supports GeForce 400 series accelerators, and was able run a qualification sample of GeForce GTX 470.

The card was using A3 revision GF100 silicon. The driver's System Information dialog revealed that the card indeed has 448 CUDA cores (SIMD units). Further, it has 1280 MB of memory, and a 320-bit wide memory interface. NVIDIA also changed the way it represents memory clock speeds. Since it is using GDDR5 memory, while the memory has an actual clock speed of 1000 MHz, the data rate (DDR speed) is represented first, as 2000 MHz, and "effective speed" next, which is 4000 MHz.
