NVIDIA GRID K520: specs and benchmarks

VS

Summary

NVIDIA started GRID K520 sales 23 July 2013 at a recommended price of $3,599 . This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 4 GB of GDDR5 memory clocked at 5 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 160.0 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 267 mm. 1x 8-pin power connector is required, and power consumption is at 225 Watt.

It provides poor gaming and benchmark performance at 9.07% of a leader's which is NVIDIA GeForce RTX 4090.

Synthetic benchmark performance of GRID K520. The combined score is measured on a 0-100 point scale.


Combined synthetic benchmark score

This is our combined benchmark performance score. 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.

Passmark

This is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various types of 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.
