Almost no improvement in performance after overclocking.
Almost no improvement in performance after overclocking.
I think you're being too detailed about this. Laptop GPUs are known for being tough to overclock due to thermal and power limits, and real improvements are usually under 5%. You shouldn't expect noticeable jumps beyond 4-5 frames per second from games that previously ran at 60 FPS. Nividia managed only a 3 FPS increase on their minimum settings when tested (116 stock vs 119 OC'ed) for the mobile 1080. That’s less than a 1% improvement. Will you really see a 1% change in minimums on your laptop screen? Probably not.
Finding reliable information about overclocking a laptop 1060 is tough since people rarely do it. But for a 1070, I’ve seen these links: http://forum.notebookreview.com/threads/...op.802768/ and http://voltground.com/haven/threads/169/. They show that even after trying various settings, the gains on a laptop 1070 stayed under 1% despite experimentation, including lowering voltages to boost clock speeds.
The main issue here is why you’d want more than 60 FPS on your laptop, given that most monitors are limited to 60 Hz. Unless you’re playing CSGO, that might not make sense.
What laptop model do you own?
Also, keep in mind that Unigine Heaven is an older engine, which could account for the stronger performance improvements you notice with your R9 290.
Be satisfied with the results you get, but stay very alert to monitor temperatures constantly, especially during long gaming sessions. Heat inside a laptop—even at around 70°C—can gradually harm the plastic casing and eventually cause serious damage over time (just based on my experience).
I understand, thanks Jester. What temperature ranges are labeled as "dangerous" for modern laptops? I definitely don't want my components to burn up, especially when overclocking the GPU. My laptop is an ASUS ROG GL502VM-DS74. It's a solid machine, but I prefer keeping its temperatures below 80°C. For longer gaming sessions, I’d recommend targeting around 70°C by tweaking the fan speed. If you're using MSI Afterburner for overclocking, it lets you adjust the GPU voltage and build a fan curve to help control temps.
