Rumor: Specifications of NVIDIA GeForce GTX 880 GPU Leaked

The alleged specifications of the NVIDIA GeForce GTX 880 GPU have been leaked. The Maxwell-based GPU boasts of a new GM204 graphics core, with a whopping 3,200 CUDA cores!

The new graphics card is touted to deliver up to 5.7 TFLOPS for single precision floating-point operations. It is manufactured on a 20nm process, and is packed with 7.9 billion transistors. According to, the GeForce GTX 880 will operate with a base clock of 900MHz, and a turbo boosted speed of 950MHz.

It will come with 4GB of DDR5 of video memory, rated to operate at a clock speed of 7400MHz; however, its video memory bus interface is 256-bit wide. Please refer to the table below to see how the alleged NVIDIA GeForce GTX 880 stacks up against its closest NVIDIA GeForce counterparts.
