Radeon HD 8590M 

Released March, 2013
  • 750 MHz
  • 2 GB GDDR5

These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

Intel is so much focused on the power output of the Core M die that they even designed a new PCH known as Broadwell PCH-LP which is focused on power.

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.
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.

Nvidia Maxwell goes mobile with GTX 980M and GTX 970M

by Slobodan Simic |
www.fudzilla.com
Despite their same name, mobile GPUs are always way below their desktop counterparts for obvious reasons, and while that might happened before, the new Maxwell 2.0 changes everything and closes the relative performance gap placing the performance of the mobile GTX 980M at around 80 percent of the GTX 980.
Efficiency is quite impressive considering the GPU is still based on the 28nm manufacturing process.
Another key enabler of the Core M processor is the use of 2nd generation FIVR and 3DL for power efficiency delivery.
There’s a small section dedicated to the memory and I/O controllers at the bottom of the die while along the right side, we can note the system agent, display engine and memory controller.
