Quadro P4000 Review
Recently we have been able to do some more graphics card testing for the Pascal cards from NVIDIA. With more software on the market taking advantage of the GPU for compute purposes the graphics card is taking on an even more critical role depending on the users workflow and needs.
Externally the P4000 is almost identical to previous generation M4000. The P4000 remains a single slot card with four display port connections that are now 1.4 spec versus the 1.2 with the M4000. The specifications have increased with the new Pascal architecture to give a significant boost in performance while keeping the same form factor and power consumption.
With the change to the P series the 4000 series card now has 1792 CUDA cores compared to the M4000’s 1664. The P4000 still has 8GB of memory just like the M4000 but with an increased bandwidth of 243 GB/S from 192GB/S in the M4000. The increased performance and updated display port connections allow th
e P4000 to support up to four 5K monitors @ 60Hz or four 4k monitors @ 120Hz.
The tests for this card were all ran on our standard benchmarking machine using an Intel Xeon E3-1270 v5 CPU, 32 GB of ECC RAM and a Samsung SSD to allow straight across comparisons to the previous test results. In addition to the standard tests a new benchmark using SolidWorks Visualize has been added to highlight the GPU rendering capabilities. This is possibly the last generation of cards that will be tested on this machine since we have a new testing machine in the works to take advantage of the latest hardware. More information on that in the next few weeks as the P-series testing is completed.
This card proved to be an interesting benchmark. Test scores from SPECView and the TMC scripted test showed remarkable improvement but the Cinebench score only improved by 7%. In actual usage in a CAD workflow (SolidWorks/AutoCAD) the M4000 and P4000 perform about the same when it came to user experience. Once part of the workflow reaches a heavy GPU load though there is a major difference in performance. Since currently (if buying new) the P4000 and M4000 are very similar in price the P4000 would be the best choice. The next test will be on a P2000 which could be interesting if the gains from M series to P series are similar on the lower range cards.
Unfortunately, there was not a chance to test the 5k capabilities of the card since we do not have any 5k monitors or a real reason to purchase one yet. Many customers are still working on adjusting to the availability of 4k monitors so I doubt 5k will be common in CAD anytime soon. If or when the opportunity comes up though we will test and update with the results here.
