AMD has not been exactly shy about the new Ryzen series of CPUs, and neither has HardOCP. We have had five articles and reviews outlining the Ryzen 7 if you are not up to date.
Back on March 15th, AMD gave us a big "sneak peak" into what exactly the upcoming Ryzen 5 would have in store. You can check out AMD's full slide deck here.
However, it is not hard to outline all the differences between the entire product line fairly quickly.
As you can see above the biggest differentiating factor is the difference in the number of cores. Where the Ryzen 7 family is identical in terms of architecture, and cores and threads, the Ryzen 5 has changes through the models. First and foremost are the number of cores and threads. The 1600X and 1600 have 6-Cores/12-Threads, and the 1500X and 1400 have 4-Cores/8-Threads. There are also differences in the L2 and L3 cache, with the one that should probably be highlighted the most is with the Ryzen 1400 having half the L3 cache (8MB) of the rest of all its bigger brothers (16MB).
Worth mentioning also is that the Ryzen 5 1600X PIB (Processor-in-a-Box) does not come with an included CPU cooler. The 1500X and 1600 CPUs come with an included Wraith Spire cooler, and the 1400 with the Wraith Stealth cooler as shown in this slide. I am not sure on the logic behind this, but that is not our call.
The Ryzen 5 CPUs we are testing today were purchased online a couple weeks ago. The AMD review kit came with a model 1600X and 1500X. We purchased two 1600 and two 1400 processors, so our review will be a bit different than most. We did spend all last week testing our four CPUs for maximum stable overclocks under load. Today we will be sharing benchmarks and analysis with you.
We are going to be showing you our Ryzen 5 and Ryzen 7 CPUs clocked at 4GHz. This should give us a good apples-to-apples testing scenario. With our Intel CPUs we are going to be showing those at 5GHz. All these clocks reflect upper-end overclocking on retail AMD and Intel CPUs. That said, we have found 5GHz on our Intel CPUs to be much easier if those are delidded/relidded.
Below is a quick picture of both our systems as tested. The chart below outlines our hardware configurations used for all our benchmark numbers here today. Given that AMD had released AGESA microcode here recently, we have re-run all benchmark numbers with the newest UEFI and AMD chipset drivers. We also chose to use new data for Intel as well so that way we are sure we have the most up-to-date software for both AMD and Intel.
