VideoCardz reports NVIDIA's upcoming GeForce GTX 880M will not use a new architecture, it will basically be an updated GeForce GTX 780M. Rather than being a mere rebrand, this new GK104 variant will feature higher clockspeeds and double the memory of its predecessor. The GTX 880M will reportedly have a 954MHz core, 993MHz Boost and 8GB GDDR5 memory clocked at 5000MHz.
According to leaked 3DMark benchmark scores, the GTX 880M is around 12 percent faster than the GTX 780M. This new laptop graphics card is expected to be available in February.
All of them have GK104 with 1536 CUDA cores. Of course there was 680M, but still it was the Gk104, only from desktop 670. So what does it mean exactly. It means that NVIDIA might still be holding a faster GeForce GTX 880MX for later, possibly equipped with GK110 GPU. If not, then I find this quite unfortunate to reuse the same GPU for three flagship models (seriously NVIDIA?).
The biggest improvement over previous flagships is obviously the memory size. NVIDIA has been doubling the frame buffer ever since and decided to go for 8GB with the latest GTX 880M. I’m not sure who really needs it, especially with 256-bit interface, but it’s surely a good marketing stunt.
