NVIDIA Quadro K620: specs and benchmarks

NVIDIA Quadro K620


NVIDIA started Quadro K620 sales 22 July 2014 at a recommended price of $189.89. This is Maxwell architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 2 GB of 128-bit memory clocked at 1.8 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of .

Compatibility-wise, this is 1-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 160 mm. No additional power connector is required, and power consumption is at 41 Watt.

It provides poor gaming and benchmark performance at 8.59 percent of a leader's which is NVIDIA GeForce RTX 3080 Ti.

Benchmark performance

Non-gaming benchmark performance of Quadro K620. Note that overall benchmark performance is measured in points in 0-100 range.

Overall score

This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.



This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.


Octane Render OctaneBench

This is a special benchmark measuring graphics card performance in OctaneRender, which is a realistic GPU rendering engine by OTOY Inc., available either as a standalone program, or as a plugin for 3DS Max, Cinema 4D and many other apps. It renders four different static scenes, then compares render times with a reference GPU which is currently GeForce GTX 980. This benchmark has nothing to do with gaming and is aimed at professional 3D graphics artists.
