Precision 7560 & 7760 Owners' Thread

How much RAM do you have?

 

It is, yeah. Reads like a salty 10-year-old wrote it, heh.

Pity is that their site traffic is still as high as ever, because they provide the most comprehensive benchmarks for all sorts of PC configurations.

 

I don't compare percentages, the point scores are more useful to look at. Your new CPU is 2x faster in multicore than your old one.

 

Also forgot to mention this: in TimeSpy, the GPU could maintain a constant 110-115W the duration of the test.
And also the fans have a lot of blades. I would say twice as much as my XPS 15. Maybe this minimal cooling increase has allowed them to increase the GPU wattage to 115W without any negative impact to temps.
My RAM should arrive later today and I will check RAM stability and run a bunch of benchmarks.

 

Here's many 7760 Geekbench 5 scores (not from me) for different CPUs. Maybe some are from participants here !

No GB score on Linux yet.

Note: GB scores are quite affected by memory speed. Whose details (and more, such as power plan) can be seen appending .gb5 to the URL of a GB score page.

 

These high-end NVIDIA GPUs have always been able to stick the power limit without trouble. When I did tests on a Quadro P5000 (...a bit old, but the most recent high-end GPU that I have had access to...), I ran one of the Fire Strike tests in a loop so it wouldn't break for loading screens or anything. 110W power draw, 100% GPU utilization, GPU-Z reporting power throttling under "PerfCap reason", and the GPU temperature never went above the low 80's. I suspect that it would be a similar situation with these newer GPUs (feel free to try it).

Because the power use is spread out across so many cores, they power throttle well before they would have to thermal throttle in almost all workloads. So a constant frustration of mine has been why is the power limit set to 110W (now 115W) when there a good amount of thermal headroom for the GPU. It might have to do with limitations on power delivery to the GPU core, or other considerations. @Dell-Mano_G previously stated that in this generation they were allowing the GPU to boost up to 140W in some cases (NVIDIA Dynamic Boost 2.0?) so I am disappointed if you are really seeing the GPU power capped at 115W when there is not a high load on the CPU.

Any RTX A5000's out there yet? Maybe they only increased the power limit for that one...?

 

I will refrain from CPU benchmarks (to avoid confusion) until after I upgrade the RAM. However, my CB20 score looks veryyyy promising with only 8GB of RAM. It's almost exactly twice as much as my XPS.

 

It could have went up to 140W, but at the end of the test, it was at a stable 110-115W. I will test with Furmark looking at wattages.
I'm testing battery life right now. Looks like I'm getting 2.5 hours with web browsing and moderate background tasks (downloading files, music playing). I'm on "cool" thermal profiles and on "Better battery" in Windows. Not bad considering I have the screen at 120hz. Also, the response time on the screen is amazing compared to the XPS. Almost no blur when moving the cursor on a dark background. Seems like they possibly used a gaming screen.

Edit: I'm on only DGPU mode, so that's why moving around the screen (Scrolling) tanks battery life. The dGPU idles at 15W, and when scrolling, it goes up to 38W.

 

Seems like the battery life is worse when the screen moves such as scrolling.

 

Yup probably the same 4K 120Hz panel found in some high end gaming laptops.
It's not like there are zillion panel manufacturers making such panels.
Kudos to Dell for offering that option.
