i5-7500 slower than i5-8500 ?

[jsicd]

Hi guys,

i've tested some machines with ident config and software (windows 10).
version PassMark 9 1025 used

CPU	RAM			CPU	2D	Memory	Disk	3D	result
i5-7500T	8 GB	2400 MHz		7070	720	2013	9151	1026	3274
i5-7500	8 GB	2400 MHz		7465	813	2129	8159	968	3391
i5-8500T	8 GB	2666 MHz		9812	658	2211	23331	620	3018
i5-8500	8 GB	2666 MHz		11391	661	2285	20854	597	3053

why have newer CPU types a lower score?

thx for your help

The PassMark score is a combination of the other individual marks. If these are truly the same configuration (e.g. same parts, besides the CPU), then from the results you provided, you should investigate the hard drives installed on the systems. The CPU Marks themselves show that the i5-7500T < i5-7500 < i5-8500T < i5-8500.

hi, thx for your info.

well, both SSDs are NVMe

i5-7xxxx -> 2400 MHz Toshiba SSD (half speed, dunno exactly why - i get in ASS benchmark 1/5 of write speed as well)
i5-8xxxx -> 2600 MHz Samsung SSD

2D and 3D Tests are different (newer CPUs have lower score).


well, i've found some benchmarks results of older version - tested with i5-7500T -> only PassmarkRating
PerformanceTest 9.0 1020 64-bit: 2984
PerformanceTest 9.0 1024 64-bit: 2920
PerformanceTest 9.0 1025 64-bit: 3274

hmm, why are there such differences shouldn't it be nearly the same?

thx and BR

You would need to look at the individual results to see which score changed. Something obviously changed a bit. e.g. new updated device drivers, maybe the disk is now full and it wasn't before. etc..

have sent u an email with log files.
seems like the DX10 tests are not been done; maybe this could cause low performance
