Tiger Lake exhibits significantly greater memory latency when compared to Comet Lake.
Tiger Lake exhibits significantly greater memory latency when compared to Comet Lake.
CPU models include i7-11800h and i7-11900h. RAM capacity stands at 64 GB. GPU options are nVidia RTX 3050 and 3060, with SSD/HDD/optical drives totaling 1TB. I acquired three new ASUS TUF F15 2021 (FX566HC) units. The memory latency is double that of the previous ASUS TUF F15 (FX566LI, 10870H). Attached screenshots show Passmark results: older FX566LI recorded 26ns, newer FX566HC reached 45ns; AIDA64 reported 55ns on older and 76ns on newer. Overall performance improves significantly. The new chipset HMO570 represents an upgrade over the previous HMO470.
I believe the impact won’t cause any significant slowdowns beyond the standard tests. If we need to compare, the change is relatively small.
Thank you for your response. I've observed a fairly noticeable variation in database operations. While expecting the opposite, I see better performance in Tiger Lake compared to Comet Lake. The firmware updates haven't resolved the issue either. The latency gap remains substantial even after benchmarking.
adding that i wasn't able to find any similar benchmarks anywhere. it almost certainly isn't a chipset issue as hm570 is an upgrade over hm470. can't be a bad model as have three different ones. if it's indeed a tiger lake issue very surprising that no one noticed
