GDDR5 is used as dedicated memory for graphics cards, and its frequency is much higher than that of DDR3 as a technology support. On some products, if you want to reduce performance and cost, some vendors will use GDDR5 instead of DDR3.
According to Anandtech report, NVIDIA quietly updated at the end of March A batch of GT1030 graphics cards with DDR4 as memory.
Pythago, MSI and Gigabyte have all shipped, and their memory speeds are all 2100Mbps (2100MHz), which is much lower than the previous 6GHz GDDR5. This also leads to 2GB 64bit at the same time. The total bandwidth is reduced from 48Gbps to 16.8Gbps.
Since the GPU core (with two types of GP108-300 and GP108-310) has also tapped down to about 1.15 GHz, the power consumption of the entire card is further reduced to 20 W.
Taking into account the complete core GT 1030 under 720P moderate special effects, "Tomb Raider: Rising" stable 40FPS +, this new 'knife card' is also not considered?
