AIDA64 CPU and Memory

Memory Read

AMD Ryzen 7 5800x versus Ryzen 7 3700X AIDA64 Memory Read

The memory is running at DDR4-3600 CL16 on both CPUs, and we see identical performance between the CPUs on memory read performance at around 50GB/s.

Memory Write

The same is also true on memory write performance, both CPUs are pulling 28GB/s of memory write speeds.

CPU Queen

AMD Ryzen 7 5800x versus Ryzen 7 3700X AIDA64 CPU Queen

The CPU Queen test is an integer benchmark that focuses on branch prediction and misprediction penalties.  It is multi-threading aware. The AMD Ryzen 7 5800X is 12% faster than the Ryzen 7 3700X in this simple integer benchmark test. PBO adds just 1% more performance.

AES

Here is the definition from AIDA64 of what this test does exactly, scroll down to AES.

In very complex AES encryption, the Ryzen 7 5800X has a huge advantage over the Ryzen 7 3700X, it’s a whopping 100% faster! PBO adds about 1% more performance.

SHA3

Here is the definition from AIDA64 of what this test does exactly.

AMD Ryzen 7 5800x versus Ryzen 7 3700X AIDA64 CPU SHA3

The AMD Ryzen 7 5800X sees a 51% performance improvement in SHA3 versus the Ryzen 7 3700X. PBO advantage is negligible. It seems AES and SHA3 are vastly faster on Zen 3 versus Zen 2.

Cache and Memory Benchmark

If you would like to compare the L1, L2, and L3 cache performance and latencies, we will show the screenshots from AIDA64’s Cache and Memory Benchmark below. You can see how the cache performance changes between the Ryzen 7 3700X and Ryzen 7 5800X.

  1. I built 4 systems for people using the 3700X. I was really hoping there would be a 5700X. Or they could drop the price on the 5800X, that would work too. 3700X and 5800X are both good CPUs, but the superiority of Zen 3 really shines through. I wasn’t expecting an article like this, nice surprise, thanks Brent.
  2. I’m on a 5800x for my gaming PC. Very happy. I came from a 3800x. Which seems silly, but who cares. HAHA
  3. Cool to see a side by side between the two. I had considered upgrading to a 5800X, but think I’ll hold on to my 3700X for a couple more years. At 1440P the gaming difference is probably 2-5%, so it really doesn’t make sense.

    Curious, why was PBO not enabled for the 3700X?

  4. So basically for gaming at ultra / 4K it is worthless to upgrade, thanks for that, now my itch to replace my 3700x is completely gone.
  5. It was a very nice incremental upgrade. The biggest benefits IMO were better RAM compatibility / higher RAM clocks, but the higher power envelope and clock speeds were nice.

    I wouldn’t see it as a necessary upgrading coming from Zen2+ either, but if you were on anything older (Haswell, for me), it was a very nice boost.

  6. I made the change from the 3700X to the 5800X and have enjoyed every single bit of improvements so far.
  7. So basically for gaming at ultra / 4K it is worthless to upgrade, thanks for that, now my itch to replace my 3700x is completely gone.

    Yeah.. That’s why I left my 3700X at home, and went with the upgrade for the work machine. I am noticing a good performance boost for my work applications for sure.
