    Recently we looked at the performance differential between DDR4 and DDR5 on Alder-Lake, Intels Gen 12th series processors. Today we review a G.Skill TridentZ5 6400 CL32 (!) DDR5 kit to see what the p...

    What's the deal with testing ddr4 3200 cl36? wow. That timing is extremely loose. 3200cl14 would be much closer to those high-frequency ddr5 kits.

    Thanks chief, great review.
    So basically if I play QHD or 4k I should not give a crap about memory, just buy the best price/perf.

    You are always gpu bound at high resolutions so memory and cpu matters little. Still you should give a crap :p

    Thank you for this test.
    This is the second test with the same outcome, 400-600€ memory kits are only worth it for overclock highscores.
    There are going to be comment like: "you need to disable E-cores and overclock ringbus" "why not 7000? this is where the magic starts to happen" the timing comment already happened.

    Just a small note, page 7 says "Memory DDR3 / DDR4 Read MB/sec".

    Great article, very interesting!

    Ok seems like ddr4 on intel 12 is still future proof.
    Since gen 13 or gen 14 will force a mother swap again you can postpone the decision

    overclocking used to be the budget way of gaining performance. Now it's the "rich guys" way of gaining 5fps.

    because of everyone ocing everything, and they just decided to do it themselves, and make some extra cash for binning stuff more.

    Well that was interesting, might be the first batch of DDR5 that trully feels above DDR4 across the board.

    wow once pricing comes down to sane levels this kit actually makes sense performance wise i would have liked to see some higher speed ddr4 thrown into the mix to actually compare 3200-3866 with cl 14-18 on the same cpu, I don't really get why 3200/cl36 is even being shown here its an unrealistic speed that i hope no one uses.

    I would really like to see how ddr4 at 4800mt/s + on alderlake performs, particularly for software that actually gains from the extra bandwidth.

    Alder lake can't run speeds that high. The absolute max you will see is around 4266MTs

    Gear 1 yes, gear 2 5600mhz+ ddr4

    Take a look on page 6, last image:
    [​IMG]

    3200CL36 is DDR5.
    The point being to show how a slow DDR5 memory kit will perform.

    Those results dont look feasible.
    Take the last 2, there is an increase of 3% in memory b/w resulting in a 13% fps increase.
    I dont think so :)

    Most likely it's just you that reading the numbers wrong ;)

    I took the figures from that graph, the graph also shows the large fps increase for the small b/w increase.
    The issue didnt stem from my post.

    DDR5 3200CL36 kits don't exist.
    The slowest DDR5 you can buy is 4800MTs

    True but Gear 2 is irrelevant for DDR4.

    There are two performance metrics in memory bound scenarios. Bandwidth limitations and latency. You can increase bandwidth infinitely but it won't matter if WoW is limited by total latency(which it is)

    That's why there is a huge gain with "fully" tuned timings because the tweaked timings reduce total latency by a significant amount
