I know that some will say that "real use" performance is what matters, however I am disappointed that my Nexus 5 gets substantially lower Antutu scores than all other Snapdragon 800 powered phones, which all seem to achieve scores above 30000.

My Nexus 5 has scored less than my HTC One which has Snapdragon 600.

I rooted my Nexus and ran Trickster mod to monitor the CPU load, CPU temp and CPU clock frequency.

I found that the standard kernel starts to throttle Snapdragon 800 SOC on Nexus 5 at 63C, initially dropping to 1958 MHz (from 2265 MHz maximum) , then as temperature continued to rise up to maximum of 69C it throttled further, 1728 MHz, and eventually dropping CPU to 1036 MHz.

Trickster mod doesn't display GPU clock rate on Nexus 5 standard kernel so I don't know if GPU is also throttling, however with such aggressive CPU throttling it does impact performance including video frame rates significantly.

What are your experience with this matter ?

Just wait for the custom kernels to start rolling in.

that is no good News!

but we have to find out if that is in any way related to the quality of the cpu you got.
you know that cpu binning thingmim thinking of. maybe you gut very Bad luck and the worst Type of cpu that there is when it comes to snapdragon 800.

Feel free to check out my antutu benchmark section (after the power on test) of the video and the 3dmark section (at the end) to see what happens. 3dmark doesnt throttle it seems, but antutu definitely does.

You DO know that most manufacturers cheat on benchmarks, right?

Love the 'Maxed Out!" score on the 3D Mark Extreme test for the Nexus 5 ! xD
That's quite impressive, whatever the Antutu score may be

But, does the phone gets hot when performing benchmarks ? Is it the reason why it throttles on Antutu ? Or maybe just a software issue

The g2 got hot on the buttons at the back and the other phones all get warm to the touch but nothing that you would expect to create a thermal incident.

Right ^^' No problem with a bit of heat, that's absolutly normal. But I'd like to be able to touch my phone while playing that's it x)

They do. But point here is not cheating but thermal throttle.
However, coming from a s4, you can raise the thermal limit when custom kernel comes out. I remember thernal throtttle on s4 was like 68 or 70.. Raised the thermal throttle to 100, no problem.
