First # on the left is the place indicator; the second # from left is bandwidth in GB/sec; the third # from left is DDR RAM speed; fourth # is the most important RAM timing, CAS latency; fifth # is total or true latency.
DDR3:
10. PC3-14,900: 1,866 DDR @ CL 9= 09.64 ns
DDR4:
04. PC4-17,000: 2,133 DDR @ CL 16= 15.00 ns
09. PC4-21,300: 2,666 DDR @ CL 13= 09.75 ns
lmfao, so now you're willing to admit, 6 or 7 pages later, that what I pointed out in my first post was correct, that DDR3 1,866 CL 9 and DDR4 2,133 CL 16 are equivalents, making what I said to begin with, that some site using DDR4 2,666 was giving an advantage to the CPU that used DDR4.
According to the table you provided:
DDR3 1866 @ CL9: 09.64 ns
DDR4 2133 @ CL16: 15.00 ns
I fail to see how these are equivalents, since their supposed true latency, according to you, is massively in favor of the DDR3.
Furthermore:
DDR4 2666 @ CL13: 09.75
The fastest DDR4 2666 in your table gives a true latency that is worse than the DDR3 used, though the advantage is minor here.
It seems to me that the test that used DDR3 1866 CL9 vs DDR4 2666 CL13 is the one that compared equivalent RAM, while the one that used DDR3 1866 CL9 vs DDR4 2133 CL 16 gave a massive advantage to DDR3 in terms of RAM latency.
