GM108 supports DirectX 11.2 (feature level 11.0 only) as well as DirectX 12.ĭue to their identical specifications, the Quadro K620M offers a similar 3D gaming performance as the consumer GeForce 840M. The larger size can reduce some of the memory traffic to allow for a relatively narrow memory interface without significantly hurting performance. Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90% of the performance of a Kepler SMX with 192 ALUs. GM108 features 3 SMMs and thus 384 shader cores, 24 TMUs and 8 ROPs (64-bit interface).Īnother optimization is the massively enlarged L2 cache. OpenGL performance, for example, should be significantly better than with GeForce graphics cards of similar specifications.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. Usually, the GPU comes with 2 GB DDR3 memory clocked at 1000 MHz (2000 MHz effective, 16 GB/s). The Quadro K620M is the successor to the significantly slower Quadro K610M. It is a Maxwell-based GPU built on the GM108 chip with 384 shader cores and manufactured in 28 nm by TSMC. The Nvidia Quadro K620M is a DirectX 11 and OpenGL 4.5-compatible graphics card for mobile workstations. NVIDIA Quadro K620M ► remove from comparison
