Interesting info appeared on the mighty intrwebzz today as apparently an engineering sample (ES) of the GeForce GTX 880 was intercepted on its way from a factory in China which was inbound for a dev center in India, we kid you not. The story gets even better as apparently the shipping manifest of the package was obtained by Chinese press.
That manifest mentions "GM204" and "8 GB GDDR5,". And yeah, that is also the most important stuff found on the manifest :) The Nvidia Maxwell based GM204 will be the followup of the GK104.
The GPU will get 3200 shader processors if we can believe the rumors that is. 8 GB on the card seems rather excessive though, perhaps an engineering sample that later on will end up as a 4GB SKU.
The leaked specs will see the DirectX 12-capable GPU feature a streaming multiprocessor Maxwell, or SMM, SIMD design that is found in the also Maxwell-based GeForce GTX 750 Ti. The GeForce GTX 880 will just feature more of those SMMs, spread across multiple graphics processing clusters (GPCs) and see some extra performance when compared against the GTX 780 Ti. We should expect something along the lines of these specs
- GM204 silicon
- 7.9 billion transistors
- 3,200 CUDA cores
- 200 TMUs
- 32 ROPs
- 5.7 TFLOP/s single-precision floating-point throughput
- 256-bit wide GDDR5 memory interface
- 4 or 8 GB standard memory amount
- 238 GB/s memory bandwidth
- Clock speeds of 900 MHz core, 950 MHz GPU Boost, 7.40 GHz memory
- 230W board power
So we have a rumored 3200 CUDA cores versus 2880 on the GTX 780 Ti. Base clocks increased from 875MHz and 928MHz for the Base Clock and Boost Clocks, respectively on the GTX 780 Ti, to 900MHz and 950MHz on the GTX 880. Interesting is that the manifest mentions 47,000 Indian Rupees which converts to a value of US $780, well .. here's that manifest, courtesy to Chiphell.
GeForce GTX 880 ES To get 8 GB Memory ?
