The latest rumor from Tyden.cz has allegedly detailed the Nvidia GeForce GTX 880, which is set to be the company's flagship Maxwell-based graphics card when it launches later this year. Of course, it's always worth taking rumors with a grain of salt, but the following specifications could well be accurate.
The GTX 880 will reportedly utilize a GM204 GPU based on Nvidia's 'Maxwell' architecture that we first saw in the GTX 750 Ti, but as the naming scheme suggests, it won't be a fully enabled part. Manufactured on a 20nm process, we should be expecting 7.9 billion transistors with more graphics processing clusters (GPCs) than the 750 Ti's GM107 GPU.
Rumored specifications include a huge 3,200 CUDA cores, plus 200 TMUs and 32 ROPs which fits with Maxwell's use of relatively fewer TMUs and ROPs compared to 'Kepler' cards. The core will run at a clock speed of 900 MHz, boosting to 950 MHz where necessary, delivering 5.7 TFLOPs of single-precision power.
As for memory, we can reportedly look forward to 4 GB of GDDR5 at 7400 MHz on a 256-bit bus for 238 GB/s of bandwidth. This is less memory bandwidth than the GeForce GTX 780, but differences in the Maxwell architecture should still mean the GTX 880 is faster, assuming the rumored information is correct.
Maxwell's inherent power efficiency sees the TDP for this flagship card sit at 230W, the same as the GTX 770 and less than the GTX 780, despite being allegedly faster. Time will only tell if these specifications are, in fact, true, with the card set to launch mid-year.
