NVIDIA GeForce GTX 880 Details Surface
Okay, so this again is a speculative post, but I just noticed that some information regarding the pending GeForce GTX 880 is spreading like a hot fire on the web. Basically according to a report from Tyden.cz and Expreview the pending GeForce GTX 880 would be based on Nvidia Maxwell NVIDIA's GM204 GPU. The product would get 3200 Shader processors and almost 8 Billion transistors. Apparently this is not even the flagship GPU, but if you have a peek at the specs (which you should take with a grain of salt) then the DirectX 12 compatible GPU would be SSM enabled, streaming multiprocessor Maxwell.
That is a SIMD design we have seen on the 750, but with more Shader clusters. The Nvidia GM204 silicon would be 20nm and gets 7.9 billion transistors with a whopping 3,200 CUDA cores. The product would get 200 TMUs and 32 ROPs offering a 5.7 TFLOP/s single-precision floating-point throughput. Memory you are looking at a 256-bit wide GDDR5 memory interface with 4 GB being the standard memory amount. With a memory clock-speed of 7.4 Ghz that would get the product a 238 GB/s memory bandwidth.
The reference products would get a 900 MHz core with 950 MHz GPU Boost and a 230W board power. Spotted through PCTuning Tyden.cz and Expreview.
The specs are to be considered highly speculative.

My thoughts exactly...
7400 MHz GDDR5 to push through that narrow bus width?

I don't understand the whole 256bit, 384bit and 512mb bit thing, just a number to me that is meaningless and has no impact on anything, it doesn't seem to matter in games at all. It is like ram latency and speed, all meaningless to me, none of it impacts game performance, I've tried loads of different types of ram and the FPS is always the same. Same with bit rate, has no impact on games.

If you imagine the amount of data that your gfx card is processing as a motorway, the speed of the traffic is the memory speed and the bus size is the number of lanes.
Bandwidth = bus size x memory speed.
If you have enough bandwidth then great and they don't build gfx cards that are crippled in that aread but trust me, there is a point where if the memory bandwidth is too low, your gfx card performance will suffer and bottleneck the rest of the GPU.
Awesome that 880 rumours are starting. It looks like another 680 (not the full die) Is this a response to the leak of Volcanic Islands being expected this year?
What happened to 2015 for 20nm? Exciting times ahead! Yay for competition.

well that surely sounds far more interesting than both titan-z and 295x2.
