DDR3 vs. DDR4: Which Ram is Best for Games
Topics Covered in the Article
Anyone who would like to build or upgrade a PC with an Intel CPU confronts a critical question: DDR3 or DDR4? The present Skylake generation with all the Socket LGA1151 supports both types of memory. What fits, comes on the motherboard. We tested two identical boards against one another and analyzed benchmarks.
Differences between ddr3 to ddr4
DDR4 memory isn’t entirely new. Some motherboards (Socket 2011-3) are supporting the RAM for decades, and current entry-level boards are available from just over 50 euros.
DDR4 memory differs from DDR3 in storage density, clocking, and voltage: in principle, DDR4 can handle more GB and achieve faster clock prices. The crux: The important for players latency is calculated from timings and clock frequency. The smaller the latency, the faster the machine transfers data from memory. Here is the higher clocking of DDR4 when compared with the greater timing of DDR3. For this reason, DDR3 can be faster in practice than DDR4.

DDR3 vs. DDR4: Testing
In theory, our DDR3 latch with its short timings ought to be a fraction faster than the DDR4 equal despite the reduced clock frequency. As it happens, however, the memory has little impact on matches in this case: Both the artificial benchmarks (3DMark) and the refresh rates are almost identical. There are slight differences in the system tests (PCMark). Cinebench 15 places with just under 15 fps in DDR4 mode currently properly. That didn’t surprise us the most.
What’s going on here?
Together with the DirectX feature test, the DDR4 memory increases the amount of draw calls significantly – with DX12 by 6.5 percent, together with DX11 even by 29.21 percent.
The specific test is supposed to demonstrate how efficient a graphics API like DirectX is. To do this, he defines the number of instructions a chip can send into the graphics unit within a particular length of time.
We can not honestly explain the origin of the gaps at this point. Since we analyzed only one combination, we guess that the memory controller of the processor works more efficiently with DDR4. We’ll shortly investigate the phenomenon with more DDR3 and DDR4 Chips.
