I'm just curious because nowhere else could I find detailed info about these two CPUs http://cpuboss.com/cpus/Intel-Pentium-B950-vs-Intel-Celeron-N2940 but I found it on CPUBOSS. I'm not talking about benchmarks, I don't look at them anyways, but stuff like memory bandwidth (which I didn't find for older ones on ark.intel), GPU turbo clock speed etc.
Is info on CPUBOSS correct?

The information there is mostly accurate, the GPU turbo clock speed and similar are still obtained from Intel's own specifications, pretty sure they don't make up numbers.

Intel still has that info, especially on the Core2s I remember reading a whole lot more back when I was buying mine. No idea where all that went, however.

this is the best site for mobile CPU/GPUs. It even has the info on the CPU you require:

For older models I'm pretty sure memory speed was as fast as the front side bus speed, meaning for example my q9400 at 1333mhz fsb could use 1333mhz ram at best (but it could use 1600 with some mobos no idea how well however). This one, pretty sure max is ddr2 667mhz.
For example, a computer with dual-channel memory and one DDR2-800 module per channel running at 400 MHz would have a theoretical maximum memory bandwidth of:
400,000,000 clocks per second × 2 lines per clock × 64 bits per line × 2 interfaces =
102,400,000,000 (102.4 billion) bits per second (in bytes, 12,800 MB/s or 12.8 GB/s)
So do the math on the 667mhz / 2 = around 333 and replace 400 with 333 andd you will get your bandwidth.

Thanks that's nice to know. 12.8GB/s seems small for me. I found a completely passively cooled Acer laptop that doesn't even have a hole to let the hot air out with a low TDP N2940 for an ultra cheap price. Now that I think about it I'm gonna go with an Asus one that I found. (that's why I asked about B950 and N2940 comparison)
Thanks again, you've been most helpful.

Memory bandwidth comes from the memory, not the cpu. Lowest end i3 with 1600mhz memory has the same memory bandwidth as the best i7 with 1600mhz. So if memory bandwidth is important for you, compare the memory speed.
No mem. speed isn't important for me that much. I thought that memory bandwidth is of same importance as when you compare GPUs. Like a 2GB DDR3 GPU will be worse than 1GB DDR5 one because it has less mem. bandwidth. I was just looking at the processing power when I was looking for a laptop.
