2 videocards for all known characteristics in the following categories: Essentials, Technical info, Video outputs and ports, Compatibility, dimensions and requirements, API support, Memory, Technologies. Comparative analysis of NVIDIA GeForce 930M and NVIDIA GeForce GT 640 Rev. Gigabyte GeForce RTX 3050 already on sale two days ahead of launch. EVGA GeForce RTX 3050 review leaks out ahead of the embargo. Intel Arc Alchemist engineering sample pictured once again. So, a video card with a memory chip running at 500 MHz would be referred to as having a 1 GHz memory. In order to make our table comparable to older chips, we still use the effective memory clock and not the real memory clock. NVIDIA GeForce 930M vs NVIDIA GeForce GT 640 Rev. NVIDIA happily confirms RTX 3050 is faster with raytracing on than GPUs without raytracing support. In the past, manufacturers referred to the memory clocks with double (or quadruple) their real clock rate, because DDR and other technologies based on it (DDR2, GDDR3, etc.) allow the memory chip to transfer two data blocks per clock cycle, while GDDR5 memories allow the memory chip to transfer four data data blocks per clock cycle. It is important to note that beginning in 2007, both AMD (ATI) and NVIDIA started referring to the memory clock of their video cards with the real clock rate used. To facilitate knowing and understanding the differences among these chips, we have compiled the table below. If you don’t follow the video card market almost daily, it is really complicated to understand the differences between the several different NVIDIA graphics chips available on the market today.
