I have a laptop with Intel HD 3000 graphics (i3 2370m CPU). From what I looked up the IGP has a base frequency of 650mhz and a maximum boost frequency of 1.15ghz. I was monitoring it with GPU-Z while I did some gaming and ran a benchmark in Furmark, but the clock speed never budges over 650ghz. I got the same readings with PC Wizard. What's going on here?
More about3000 graphics reaching maximum clocks
boost frequency i would think would depend on the temperature of the cpu as well. it will lower its clock when its starts to heat up, and I definitely can sense it probably heated up under furmark.
The maximum temps I monitored during everything were 47C (core 0), 52C (core 1), 52C (CPU package), and 51C (GPU). That doesn't seem high enough for thermal throttling.
you shouldnt be running furmark on a laptop. it kills the chips since the chassis most likely doesnt have adequate cooling (manufacturers cheap out this way since they know your system will never reach 100% usage)
