Precision 7560 & 7760 Owners' Thread

I got 4848 w/ 8GB RAM on an i9-11950H. Looks like an i7-11850H w/ 32GB RAM is around as fast as an i9 with 8GB RAM. I expect a 10% performance increase with the i9 compared to the i7 11850H

 

Lack of RAM and storage slots is also another reason why I didn't want a gaming laptop. It's not a problem now, but it might be in the future. And having two slots with high capacity drives (2TB) will cost more than 4 slots with cheaper, less capacity drives (1TB). Maybe in the future that will change.

 

Glad to see it going above 115W at times.
Looks like the GPU temp never went above 80C? So, impossible to thermal throttle. It could use some more power. (Even "worse" with the A5000 which will run a bit cooler at the same power level.) But ah well. They're probably pushing the limit with the VRMs that they have on the card.

As for the fan speed ramping up, it does seem like there is a long delay before it goes to full speed. You should try running it on "Optimized" and see if the behavior is any different. Sometimes I think that the fan profiles for the alternate modes are half-baked. On my 7530, "Quiet" mode might keep the fans from ramping up to max under a high workload, but it's actually louder than "Optimized" on a light workload. Sometimes they tune these in the first few BIOS updates.

 

Why would this be the case? Larger die?

 

The die is the same (both GPUs have GA104, but the A4000 has some of the cores disabled). But with the same amount of power spread out over a larger area (more cores)... physics says that it must be cooler.

 

16GB 14Gbps GDDR6 may also use 5-10W more or so than 8GB 12Gbps GDDR6, so less TDP used by the GA104 itself. The A5000 may also be using more efficient VRM phases (or even have additional phases) but we cannot really tell until someone gives high res photos of each card.

 

Regarding the Dynamic Boost for the GPU:
I'm rendering with the GPU right now (Blender CUDA) and with the Windows battery slider all the way to the right, the GPU didn't boost above 115W that often. However when I put the slider all the way to the left (CPU takes up less power when not used), the GPU quite frequently boosts above 115W. It's average power is around 118W (mostly doesn't boost above 115W).
But because each GPU needs a CPU core to function, the CPU isn't "idle"; it has one core at 100% utilization. So maybe that's why even with a total of 8% utilization, the CPU is at 27W.
I will use XTU to limit CPU wattage and see what GPU boost power I can get.
If this is an issue, I hope it's fixed in an update, because right now, Dynamic Boost isn't that useful.
On "Balanced" mode, the GPU wattages seem to be a bit more steady, but the average wattage is lower by a few watts. Temps are roughly the same between "Balanced" and "High performance" modes.

**Also, in HWinfo64, I don't the section for EC (temps and fan speeds)

 

Nice simple way to cap the CPU:
Go to Windows advanced power settings and set the maximum processor state to 99%. Set the Windows power slider to the middle option ("Better performance").

This will prevent the CPU from entering turbo boost speeds. You can watch it in Task Manager "Performance" tab and it will never hit 3 GHz. If you want turbo speeds, just move the power slider to the right.
This is nice on laptops to control the thermals & fans when you don't need high performance (just light work & browsing) and in a case like this it might also lead to a modest boost in GPU power.

 

Modern standby prevents this... would the fix be to enable S3 in the registry?

 

I upgraded to 64GB Crucial Ballistix 3200mhz CL16 RAM an hour ago. I broke a few clips of the bottom cover in the process (don't like this clipped bottom cover design...)
I didn't notice an increase in CB20 performance which was odd.
I will run TimeSpy after soon once I'm out of a class.
