A 4k framebuffer is only 300MB. So even triple buffering only uses 1GB of vram. Regardless of vram density you won't run modern titles on a 860M at 4k without using either really low poly counts or significantly stunted fps.2 GB of VRAM for 4K? HA. Yeah okay.
lol, it's not like you're going to be running many newer games at 4K with a 860m. That chip is decent for a laptop, but it still only gets 20-30 frames at 1920X1080 on newer games.. up that to the 4K, and you'll be 1/4th at.. 4-6 frames per second. lol.2 GB of VRAM for 4K? HA. Yeah okay.
Might not be intended for gaming, but those specs say it can do a pretty good job anyway.It improves the the text reading from the laptop screen so this is good upgrade! This is not for gaming, this is for work usage. I have win8.1 with DPI scaling and it work well in all office applications and other important programs too!
But a Maxwell based GPU would be quite nice because it would eat less energy when in light usage!
Dunno about the Toshiba, but the Lenovo uses the Maxwell 860m. So far I've only seen the Kepler 860m in laptops where the 870m is also available as an option. The 870m is Kepler-only, and apparently using the Kepler 860m allows manufacturers to use it as a drop-in replacement part for the lower-end laptop. But freed from that constraint, manufacturers seem to be using the Maxwell 860m.Would this be the Maxwell or keplar version of the 860m? I'm guessing keplar? Which is a shame, the Maxwell 860m is such a nicer gpu, same performance fraction power consumption and less heat.
