Earlier this month, there is much speculation that Nvidia will finally release their much-awaited GeForce GTX 800 series. Although the release date is shrouded in secrecy, it has been accidentally confirmed by a Gigabyte employee at the ChinaJoy Game Developers Conference that Nvidia will release the Nvidia GeForce GTX 880 and 870 next month, TechSpot reported.

According to the executive, which was interviewed by Expreview, he said that most of the speculated specs of the upcoming cards were correct. It was whispered in technology circles that the GTX 880 and 870 cards would be coming in with a 3,200 CUDA core, 5.7 TFLOP/s single-precision floating-point throughput, 256-bit GDDR5 memory, 4 GB standard memory, 32 ROPs, 200 TMUs, and a Maxwell architecture, as listed in Tweak Town. However, the Gigabyte employee's revelation was said to be the most interesting in graphic cards, as the new cards were said to only use 28 nm GM204 silicon instead of the rumored 20 nm GM204.

But the employee also added that Nvidia is already working on a 20 nm 204 version that will be released sometime in early 2015 and is hoping to bridge the transition of other graphics cards to 20 nm 204. This is, although good news for PC enthusiasts looking to get more power for their rigs especially with the addition of the great improvement using the Maxwell architecture, the predicted dates were a bit off as to what KitGuru has based off information in the Zauba.com database. Zauba, which monitors Indian exports and imports, indicated that the GM204 cards where shipped to the developers in early June. The shipping dates suggested that the GTX 880 and 870 cards based on GM might be released earlier instead, probably a late September or an early October rollout.

When it comes to the aesthetics and design of the GTX 880 and 870, the Gigabyte versions of the cards will most likely look like the Titan Black, said the Gigabyte employee. This is because it will be featuring a custom designed heavy duty cooler that is said to be able to go up to 650W in terms of thermal loads.

That being said, most tech-related websites and review sites have already compared the rumored specs to Nvidia's current generation of graphics cards and they are still a bit apprehensive whether the new generation can bring a lot to the table in terms of enhanced performance.

Here are the complete rumored specs of the Nvidia GeForce GTX880:

  • 28 nm 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 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
