CPU Tests: Synthetic

Most of the people in our industry have a love/hate relationship when it comes to synthetic tests. On the one hand, they’re often good for quick summaries of performance and are easy to use, but most of the time the tests aren’t related to any real software. Synthetic tests are often very good at burrowing down to a specific set of instructions and maximizing the performance out of those. Due to requests from a number of our readers, we have the following synthetic tests.

Linux OpenSSL Speed: SHA256

One of our readers reached out in early 2020 and stated that he was interested in looking at OpenSSL hashing rates in Linux. Luckily OpenSSL in Linux has a function called ‘speed’ that allows the user to determine how fast the system is for any given hashing algorithm, as well as signing and verifying messages.

OpenSSL offers a lot of algorithms to choose from, and based on a quick Twitter poll, we narrowed it down to the following:

  1. rsa2048 sign and rsa2048 verify
  2. sha256 at 8K block size
  3. md5 at 8K block size

For each of these tests, we run them in single thread and multithreaded mode. All the graphs are in our benchmark database, Bench, and we use the sha256 and md5 results in published reviews.

(8-3d) Linux OpenSSL Speed md5 8K Block (1T)(8-4d) Linux OpenSSL Speed md5 8K Block (nT)

GeekBench 5: Link

As a common tool for cross-platform testing between mobile, PC, and Mac, GeekBench is an ultimate exercise in synthetic testing across a range of algorithms looking for peak throughput. Tests include encryption, compression, fast Fourier transform, memory operations, n-body physics, matrix operations, histogram manipulation, and HTML parsing.

I’m including this test due to popular demand, although the results do come across as overly synthetic, and a lot of users often put a lot of weight behind the test due to the fact that it is compiled across different platforms (although with different compilers).

We have both GB5 and GB4 results in our benchmark database. GB5 was introduced to our test suite after already having tested ~25 CPUs, and so the results are a little sporadic by comparison. These spots will be filled in when we retest any of the CPUs.

    whut?! They were late buying the EUV equipment to save money, too much focus on profitability which will kill Intel slowly overtime. Reply

    Yup, TSMC bought about 50% of all ASML output for the next couple years while Intel only bought 5%. RIP Intel, you got what you deserve and you are going to be the next Motorola. Reply

    Like it says in the article AMD almost folded in 2015, and people were writing articles about it's demise. Seems no one has learned anything about predicting the future from that experience. The world needs competition. It doesn't need an AMD monopoly, nor an Intel one, and with good fortune RISC-V and maybe other competitors will come on the scene so we don't keep repeating the history of "Oh they're dying, and I'm rooting for it".

    Hardly likely, TSMC is the bigger fish, has almost twice the capita as Intel. Reply

    Luckily there are anti-monopoly laws ;) Reply

    Let's see how the whole ARM acquisition by Nvidia shakes out before we all start quoting monopoly laws. Reply

    RIP Anandtech, these reviews makes it hard to come in without error 504 or the site c crashing Reply
