Previously there was no GT 1030 DDR4 graphics card, so the performance test couldn't be done, but the YouTube publisher on Youtube shared what it did.videoThe comparison between the 1030 GDDR5 graphics card and the DDR4 memory version of the GT1030 graphics card is based on the following differences:

DDR4 version of GT1030 graphics card frequency dropped from 1468MHz to 1379MHz, with 2GB DDR4 memory, 64bit wide, but we previously described the frequency of only 2100MHz, compared to 6000MHz GDDR5 straight down 2/3, bandwidth from 48GB/s reduced to 16GB/s, the benefit is that TDP power consumption from 30W down to 20W, while the price is lower some, he compared the price of 80 US dollars, cut prices by 20%.

As for the performance of the GT 1030 DDR4 graphics card, he made some comparisons using the GTA 5 game.

GTA 5 quality setting, 1080p resolution, Normal quality

Performance dropped from 61fps to 36fps

This scene dropped from 65fps to 38fps

Here from 73fps to 43fps

Here is reduced from 73fps to 46fps

In general, the performance impact of the GT 1030 graphics card is even greater than previously expected after switching to DDR4 memory. The average GTA 5 frame rate is reduced from 60-70 fps to 30-40 fps, a drop of approximately 40-50%. If you look at the 0.1%low frame number, then it will drop from the previous 40+ to about 30fps, and the performance loss is still quite large.

Compared with the graphics card price drop, the performance loss rate is obviously not acceptable, the bandwidth gap is really too big, even if it is a low-end graphics card, the performance impact is still so big, do not know how other games, but on the GTA 5 The performance of the DDR4 version of the GT 1030 is clearly not worth choosing.
