Dell Precision 7680 and 7780 SOLIDWORKS Performance
How much engineering time could you save using the most powerful Dell Precision Workstations? We will compare the Dell Precision 7680 16 inch and Precision 7780 17.3 Inch mobile workstations against the Precision 7750 from 2020. The testing is done with real world engineering datasets, rather than generic benchmark tools using SOLIDWORKS solutions. Find out how Intel’s 13th Generation CPUs and the latest NVIDIA Ada generation professional graphics, stack up for CAD, FEA, CFD Simulation and GPU visualisation

While we recommend a replacement cycle of 3 to 5 years for workstations, we're not suggesting that the system is done with at that point. Just that CAD and CAE users are typically amongst the most demanding users who will benefit most from an upgrade. After all, we've been talking a lot about sustainability. The great thing is these systems have a level of performance and durability that means that they will often perform well for many years for another user in the business with less performance demands. Or alternatively, you can take advantage of Dell's asset recovery services where devices from any manufacturer can be returned, where they will be securely wiped before then, ideally being repurposed, or if of no value, the device will be recycled. So, what about performance this time? What we are comparing should be a very close match between the top of the range precision 7750 laptop from three years ago versus the precision 7686 16 inch and the 7780 17 inch laptop from 2023. whereas a new precision 7680 16 inch laptop with its comparable i7 CPU, it takes just one minute and 25 seconds on average to open around 30% faster going up to the I9 CPU in the precision 7780 improves performance further to one minute 20 seconds, ultimately around a 5% difference between the I7 and the I9 equating to the difference in maximum turbo boost speeds. The I9 extra cores won't help much for this type of operation. The performance difference also held true for the lightly threaded CAD tasks such as rebuild for more multithreaded computer aided engineering tasks such as simulation and flow simulation. The 7000 series laptops can offer up to an I9 24 core CPU, and while the number of calls utilized will vary depending on the solver, study complexity and some other factors, the great news is that these CPUs also offer the highest single threaded speeds available so you can have the best of both worlds for CAD and other workflows. For a static simulation, the three year old Precision 7750 and its six core i7 takes nearly 7 minutes to complete our example static simulation while the precision 7680 features a 13th generation i7 CPU with 20 cores it takes just 3 minutes and 25 seconds, a 50% improvement from the i7 three years ago. The latest I9 shaves another 10 seconds off of that time. moving on to the most heavily multi-threaded workflows. Next, we'll look at a CFD study of a mask using SolidWorks Flow simulation. Will the 3 to 4 times the number of calls in the latest laptops make a big difference here. This test scales to over 750,000 cells and takes over 110 minutes on the three year old i7 six core CPU of the 7750 2023 precision 7680 16 inch laptop with its i7 and 20 core CPU takes just 42 minutes While the precision 7780 and its I9 24 core CPU takes 39 minutes and 10 seconds a 60 to 65% improvement in just a few years. And again for context, last year's six core laptops took 48 minutes to do the same flow simulation to test the graphical power. We run an automated rotation test using the Nemo data set at full HD with real view graphics and shaded with edges Mode enabled. And with this complex assembly, the three year old 7750 with an RTX 3000 6GB gigabyte graphics card set a benchmark of 23 frames per second. here, the high end cards really shine with the RTX 3500 Ada seeing a frame rate of around 65 frames per second with the RTX 5000 Ada delivering more than 70 FPS. Given these cards have just been released, we may well see this improve further going forward with future software and driver updates. SolidWorks Visualize is optimized for and video graphics cards and for 2023 with the launch of Nvidia's Ada generation graphics. It's the perfect time to upgrade. With NVIDIA typically releasing a new generation of graphics every two years. The precision 7750 with the high end Quadro RTX 3000 6 gigabyte graphics card took 4 minutes and 36 seconds to render a complex underwater scene featuring the Nemo sub at 4K with 500 passes. Incredibly, the equivalent end video RTX 3500 Ada in the precision 7680 renders the same scene in just one minute and 45 seconds. To give some context, last year's equivalent Nvidia A3000 took 3 minutes and 8 seconds. So almost half the time and the new top of the range RTX 5000 Ada generation can take that time all the way down to one minute and 22 seconds. The Precision 7000 series are truly desktop replacement laptops. And while we did also test the precision 3660 desktop and it still has some advantages typically of about 10 to 20% for CPU based workloads due to the higher power limits and cooling capacity versus the top of the range laptops. However, many will trade that performance difference for the flexibility a laptop offers.
