CPUX.net | CPU-Expert - Benchmark Online

Does anyone know of this benchmark tool CPU Benchmark Online | CPU Expert (cpux.net)? 

Thing is, I've had some free time at work so I got the idea to benchmark our older laptops that are laying around but we cannot install programs that are not approved so I have to use benchmarks via web browser, that is why I used the above. But the results I'm getting is rather weird: 

 

Laptop                                           CPU                                               RAM                           Rank                          Score        Hashrate
(Intel) Lenovo ThinkPad T490s     i5-8365U (4C/8T)                          16GB DC 2400MHz    50.836 (243.433)       91.944       271 H/s
(Intel) Lenovo ThinkPad T480s     i7-8650U (4C/8T)                          16GB DC 2400MHz    61.043 (243.437)       82.920       247 H/s
(Intel) Lenovo ThinkPad T480s     i5-8350U (4C/8T)                          16GB DC 2400MHz    61.504 (243.421)       82.541       246 H/s
(Intel) Lenovo ThinkPad T14s       i5-10310U (4C/8T)                        16GB DC 2667MHz    75.211 (243.425)       72.751       219 H/s
(AMD) Lenovo ThinkPad T14s      Ryzen 5 PRO 4650U (6C/12T)     16GB DC 3200MHz    85.450 (243.445)       67.004      198 H/s
(AMD) Lenovo ThinkPad T495s    Ryzen 5 PRO 3500U (4C/8T)       16GB DC 2400MHz    135.449 (243.434)     45.833      137 H/s

 

All laptops have the newest drivers, firmwares and BIOS', and all had the High Performance power plan selected. 

But how can a 8th gen i5 beat a 10th i5 laptop with faster RAM also? I did re-run the tests multiple times. The T490s always tops the board. 

Anyhow, non of this is important, I just had some free time, so I needed something "fun" to do hehe but the results had me wondering. 

Any thoughts?

Cooling, as well with U variants the 0’s are more limited tdp variants while the 5’s are higher tdp.

Thats a sentence nobody outside of this sphere of nerd stuff would ever understand but my best guess is the 8365U is sustaining it’s boost clocks for longer than the 10310U is

I've just done a test on my Envy X360 15"  2021 with a Ryzen 7 5700U cTDP up to 25W.

 

I did the test on battery power and I have to say I'm surprised at the result. It says 247H/s even tho it is an 8C/16T chip and during the test it showed 16 threads doing 280H/s. Tbh looking at my score and the results table for their top CPUs makes me skeptical of the benchmark's ability to accurately portray performance.

 

If it's trying to show single core perf then that could explain results with the exception of the 10310U. If you need to run a browser based test (which are generally less reliable than desktop based ones) then I'd look for an alternative if one exists.

Not in this case. The ones ending in 5 for Intel in 8th gen are part of Whiskey Lake versus the normal 8th gen U series being Kaby Lake Refresh.

These older ones tended to be more aggressive with the boosting especially the i5 8300u's. Since the i5 and i7 are basically identical these results aren't too surprising.

 

The 14s is weird tho. That laptop doesn't have any issue cooling a ryzen 4750u and others so the score being so low as well as for the i3 is kinda weird.

 

Probably the benchmark isn't really reliable

There's no IPC difference between them, the Skylake underpinnings are still there. It's mostly a matter of operating clock speeds and core count at that point because not all benchmarks strain the memory.

Thanks guys, for your inputs
