Radeon HD 6490M 

Released January, 2011
  • 800 MHz
  • 512 MB GDDR5
These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

It will work at 823MHz+ GPU clock and feasture 4GB of GDDR5 memory clocked at 5GHz and paired up with a 256-bit memory interface that add up to 160GB/s of memory bandwidth.

NVIDIA Quadro M6000 Announced

by Scott Michaud |
I wonder what this means for the Tesla line, and whether we will see a variant of Maxwell with a large boost in 64-bit performance, or if that line will be in an awkward place until Pascal.
The memory, but not the cache, is capable of ECC (error-correction) for enterprises who do not want a stray photon to mess up their computation.

NVIDIA Announces Quadro M6000 & Quadro VCA (2015)

However the company is also pushing the use of Physically Based Rendering (PBR), a compute-intensive rendering solution that uses far more accurate rendering algorithms to accurately model the physical characteristic of a material, in essence properly capturing how light will interact with that material and reflect off of it rather than using a rough approximation.
However as FP64 compute is not widely used in graphics, this is not something NVIDIA believes will be an issue.

NVIDIA Quadro M6000 Leaks via Deadmau5

by Ryan Shrout |
A quick hunt on Google for the NVIDIA M6000 reveals rumors of it being a GM200-based 12GB graphics card.
Although not inexpensive, it will allow customers to get some extra mileage out of their laptop, especially with the major improvements in performance we have seen with the Maxwell 2 based GTX 980M and GTX 970M.
If you are not afraid to open up your laptop, and you are looking for a graphics boost, you may want to check out the kits which can be found at Eurocom’s site.
