No it's not.
Since skylake comes in both DDR4 and DDR3 motherboard versions, various benchmarks have come out to test the difference for the state-of-the-art 14nm cpu with the "improved" memory vs the "old" memory.
And the difference is often only 1-2%
Unless maybe the goal should be to put 32gb of memory right on the cpu die
- vardump 11y agoDifferent software needs different resources. Unsurprisingly, if the software in question is not bandwidth limited, providing more bandwidth is not going to speed it up. Most software is like that. It also truly depends on how it was optimized. The software being tested was likely optimized for previous gen configurations. It might very well favor a bit more computation over higher memory bandwidth usage. Wait until developers optimize against DDR4 Skylake systems, you might start to see 5-10% difference at that point. Truly bandwidth limited code can run up to about 40% faster on a DDR4 system, assuming typical 1600 MHz DDR3 and 2400 MHz DDR4.
