Curious if any guru is familiar with laptop Nvidia GT 550M, in Dell XPS laptops (mine is XPS L702x) being released with 144 active cores (rather than 96). When I open up my driver it states 144 cores; while Nvidia's site states there's only 96. It wouldn't surprise me if this were a driver issue, or that the 550M was just a BIOS cut down 555M. Anyone know anything about this. Thanks
The word you're looking for is shaders. What do you mean when you "open up your drivers"? You mean GPU-Z?
nvidia drivers have system information and it displays how many cuda cores the card has. @ the OP. what is your core clock speed?
The GeForce GT 550M has 96 sp (740/1480/900 MHz core/shader/mem default), the GeForce GT 555M has 144 sp (590/1180/900 MHz default). The Dell XPS L702x can have either. How much memory does the video card have? The 550M for that Dell laptop should have 1024 MB while the 555M should have 3072 MB.
It has 1GB of dedicated memory. The clock speeds and number of cores are confusing. Because if I do have the 96sp then the core clocks are way to slow. If I have the 144sp then it doesn't match the 550M description of the drivers....
GPU-Z can show wrong shader count. It wouldn't be the first time. If the nvidia control panel can show the amount of shaders then I'd go with that number instead. Clock speed can be shown as low if you are measuring it while in idle, launch a game or benchmark and read the meters again.
Yeah they're still the 475 / 950Mhz Funny thing about searching for more information on this, is now that I've made this post the number one googled page is this one.
Laptop manufacturers almost always play with the clock speeds to meet thermal/power requirements so not surprised they don't match up.
