Hello,
Please add HPL and HPCG benchmarks
for direct comparison with supercomputers ))
HPL https://www.top500.org/list/2017/11/
HPCG http://www.hpcg-benchmark.org/custom/index.html?lid=155&slid=293

AIDA64 5.97.4600 Help (F1) Benchmark guide still do not updated about using extensions AVX-512
-
Fiery
Did I understand correctly that in the reference results you publish the base frequency, but the benchmark itself is performed at the turbo frequency?
In my opinion this is an incorrect approach, which is misleading.
Some processors have a very high turbo frequency (up to +200% to Base), but it works very short time:
In my opinion, you should publish the Turbo frequency, or increase the benchmarks time to several minutes.

Hello,
Can AIDA64 measure performance of Tensor Cores?
-
1) Single-core benchmarks are very popular in reviews this year for comparing different microarchitectures (Sky lake vs. Kaby Lake vs. Coffee Lake and Ryzen vs. xxxLake). It will increase the reference benchmark results database only twice.
2) Maybe you'll write an additional benchmark specifically for "single-core mode"?
-
Hello,
1) CPU benchmarks have "Parameters" and we can select single-core mode (1 CPU). But Reference Results remain multi-core. Please add single-core Reference Results also.
2) Please add single-core mode also for Memory benchmarks.

AIDA64 v5.95 still does not support AVX-512?
-
Hello,
"FPU VP8" benchmark is very strange and do not scale on multi-core systems.
May be replace it to a more common HEVC encoding?
-
I am disappointed.
In my opinion, the benchmark should come out no later than the release of a new processor with new instructions (for this, there are engineering samples).
Very bad news - all new reviews with AIDA64 show incorrect data and do not show the real potential of the processor:

AVX-512 is not yet supported.
Thanks,
FieryOMG! But why??? CPU with AVX-512 released a year ago.

Why AIDA do not have Ryzen results anymore?

As i see in AIDA 64 Help:
"CPU Hash This integer benchmark measures CPU performance using the SHA1 hashing algorithm"
But many cryptocurrencies uses double SHA256.
Also, many cryptocurrencies uses another hash algo.
-
Hello,
Please add benchmark (Hash/sec) for some popular cryptocurrencies
-
>> We've also added a Broadwell-E i7-6850K result
Thank you. What about i7-6900K and i7-6950X ?
>> and an Apollo Lake reference
I do not see Apollo Lake results.

Hello,
Please add benchmark results for Intel Xeon Phi x200 series CPU (Socket LGA3647)

Sandra performs Stream benchmark, which is essentially a variant of a memory copy bandwidth benchmark, spiced with some simple CPU instructions performed on the copied data.
end user looks at the name of the test, he not interested how test perform it.

Thank you, but we'd like to stick with our formula -- which is used by other benchmark software (like Sandra) as well BTW.
Sandra do not have benchmark with name "Memory copy".
Sandra have bench with name "Memory bandwidth" with correct formula for this case.

From the memory interface perspective, reading 32MB and writing 32MB is considered transferring a total of 64MB data, that's why we use the formula "Score = 64MB / time_it_took_in_seconds".
It can be Ok if benchmark called "memory throughput" or "memory bandwidth". But your benchmark called "memory copy", and must show the speed of copying = 32MB/time.

We do 1/a, so we read something and then write it. It's not full duplex. And the read and write block sizes are added up together, so it's not 1/2 of read/write speed, but 1/1.
you do math calculations incorrect.
you do not must add up read and write block sizes, but you must add up read and write times.
-
>> There's no consensus in the benchmark industry about how to calculate the memory/cache copy scores
It can not be two opinions.
If you have B bytes and copying time is t sec, then copy speed = B/t bytes/sec.
-
1) Copying can be done in two ways:
a) read, then write. In this case copy speed is 1/2 of r/w speed.
b ) read and write simultaneously. In this case copy speed = r/w speed, but memory and memory controller should operate in full-duplex.
which method uses your copy bench?
2) may you can provide also single-threaded memory bench for information purposes?
-
If memory test is synthetic sum of multiple threads, how can I see more "real life" performance of single-thread speed?
-
Hello,
1) As i see, Memory Copy ≈ Memory Read ≈ Memory Write speed. How it possible? Memory and memory controller can operate in full-duplex?
2) Memory bench result is speed via one thread, or sum of multiple threads?
Please add realtime CPU frequency detection inside VM

Hello,
Please add realtime CPU frequency detection inside virtual machine (ESXi).
Currently AIDA always show base frequency.
