i7-4980HQ vs i7-5950HQ

I have a single 780 Ti SC... Don't meet your requirements.

 

As long as you can force a CPU bottleneck, you succeed.

I do it with these 780Ms, so...

 

Well since the laptop is out of commission... Tell me what you want me to do, sorry, don't feel like reading a book atm...

 

Here are the results of XTU tuning/testing for longest sustained performance with the 5950HQ in the GT80 SLI-263.

35x x4 cores @ -105mV and 35x cache, holds as long as the job runs. I monitored for over an hour before grabbing a snippet of the monitoring. The average TDP was 45.2w over the hour run. The 5950HQ TDP is 47w.



Update: To try to squeeze out as much throughput as possible, I am now running at 36x cores -100mV 36x cache. The result is an sustained average multiplier of 35.7 with average TDP of 46.855w.

As a test, I did a run at highest OC / peak performance of 41x x4 +50mV 37x cache +1.9v and the sustained multiplier was down to 31x, with higher temps.

For long jobs its best to align CPU settings at MAX TDP, with lowest voltage to CPU/cache for best sustained throughput.

 

any possibility of skylake refresh in this laptop? can really have a nice dmi 3.0 with all those 4 SSDs going upwards at 2GB/s

 

unityole, not sure how the PCIe lanes will be distributed, there may only be enough for 1 or 2 PCIe M.2 slots... we don't know yet.

No Skylake news...

 

So basically the 5950HQ acts as the 4980HQ. Good to know.

Now to see how these skylake chips will work...

Don't count on it; it'd require an entirely new chipset, which would likely require an entirely new design, unlike a simple BIOS update and using the same chipset/etc for the Broadwell CPUs.

 

uh, no lol. mobile high end cpu have 16 lanes, 8 for each GPU in this laptop. all ssd thats m.2 will be sata instead of pcie and there are 4 sata 6gbps in mobile space unless H170 changes this which i highly doubt it. 4 ssd sata 6gbps raid 0 gives 2GB/s via chipset.
