![]() The difference is not significant enough for the GT 650M to have a noticeably larger impact on your yearly electricity bills than the GeForce 930M 2GB.Īrchitecture The Kepler Architecture was NVIDIAs big step to power efficiency.Įach Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. The GT 650M requires 20 Watts more than the GeForce 930M 2GB to run. The GeForce GT 650M Mac 1GB Edition requires 45 Watts to run and the GeForce 930M 2GB requires 25 Watts. Knowing that the shader performance of the GeForce 930M 2GB is superior, it is not necessary to examine the GPUs respective Texture and Pixel Fill Rates. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 930M 2GB is 488 and by the GT 650M is 488. Latest For Nvidia Geforce Gt 650M Mac 1GB Editionīoth the GeForce GT 650M Mac 1GB Edition and the GeForce 930M 2GB have 384 Shader Processing Units. The GT 650M has 65.9 GBsec greater memory bandwidth than the GeForce 930M 2GB, which means that the memory performance of the GT 650M is much better than the GeForce 930M 2GB. However, overall, the GT 650M has superior memory performance. The GeForce 930M 2GB has 1024 MB more video memory than the GT 650M, so is likely to be much better at displaying game textures at higher resolutions. The GeForce 930M 2GB was released over a year more recently than the GT 650M, and so the GeForce 930M 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 650M. ![]() However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards. ![]() The GeForce 930M 2GB has a 28 MHz higher core clock speed than the GT 650M, but the GT 650M has 8 more Render Output Units than the GeForce 930M 2GB.Īs a result, the GT 650M exhibits a 7 GPixels better Pixel Fill Rate than the GeForce 930M 2GB. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10. Latest For Nvidia Geforce Gt 650M Mac 1GB Edition. ![]()
