Although we've only just received official information about Ryzen 3, we seem to already know everything about AMD's new R3 1200 and 1300X after running simulated benchmarks last week. Today we can see how accurate these preliminary results were and compare these impressions with the final prices.
The Ryzen 3 1300X continues to operate with a base frequency of 3.5 GHz and a boost frequency of 3.7 GHz, while the slightly lower 1200 drops to 3.1 GHz with a boost frequency of 3.4 GHz. Both parts are unlocked, making the more expensive 1300X less attractive to us at $ 130, which is only $ 40 away from the SMT-enabled R5 1400. At $ 110, the R3 1200 offers savings of $ 60 over the R5 1400 and seems to be a better buy for budget builders.
We're excited to see how much slower the Ryzen 3 processors are without SMT, especially when compared to Intel CPUs with similar prices. This is a bit difficult because Intel's CPUs, as already explained, make little sense here and the $ 80 Pentium G4560 up to the $ 190 Core i5-7400 eliminates everything. In other words, anything less than $ 180 in Intel's current offering is pointless, including the company's entire Kaby Lake Core i3 range.
We also wonder how much overclocking affects the overall picture (teaser: with the Wraith Stealth Box, the Ryzen 3 1200 reached 3.9 GHz, while the 1300X offered 4.0 GHz). Assuming they can outperform the locked 7400 and 7500, AMD's entry-level chips should sit comfortably at their $ 110 and $ 130 MSRP.
Synthetic & application benchmarks
First, the memory performance and a few brief notes. When compiling the simulated Ryzen 3 article, I used DDR4-2933 with the Ryzen 5 1400 (SMT disabled) because I found that Ryzen 3 CPUs would likely have trouble running with faster memory. So far this has actually been the case since neither the 1300X nor the 1200 would boot with the XMP setting DDR4-3200.
So I had to run DDR4-2933, which was the case with my Ryzen 5 1500X and 1400 CPUs. Still, the performance was decent and we saw over 34 GB / s memory bandwidth. This number was increased to around 35.5 GB / s after overclocking the CPUs.
We have the first CPU-related benchmark here, where Ryzen 3 1200 shows rather weak single-thread performance paired with reasonably decent multi-thread performance. The higher clocked 1300X was slightly better and adjusted the Core i5-7600's single-thread performance with a slightly weaker multithreaded performance.
After overclocking, both Ryzen 3 CPUs achieve similar results because they were operated at a similar frequency. Both were faster than the i5-7500 for both the single and multithread test.
For those interested in compression and decompression work, the 1200 in 7-Zip was a good deal faster than the Pentium G4560, but slower than the Core i3-7350K. The 1300X was much more impressive when it hit the i3-7350K and displaced the i5-7500. After overclocking, both Ryzen 3 CPUs were comfortably in front of the i5-7500.
In our Microsoft Excel 2016 test, the 1300X compared well to the lower clocked 1400, while the 1200 followed the i3-7350K, but much faster than the G4560. We overpressed the Ryzen 3 CPUs a bit more, but the 1300X still left the i5-7500 a bit behind.
We have the first of four PCMark 10 test suits that we'll look at. The data here is organized by video conferencing results, and here are the Ryzen 3 CPUs between the Pentium G4560 and the Core i3-7350K. After overclocking, they preceded the Core i5-7500.
The productivity test was arranged based on the results of the spreadsheet. Here the Ryzen 3 CPUs were at the bottom of our diagram behind the G4560. With overclocking, however, they make considerable progress in this test and can now keep up with the Ryzen 5 1600X and the Core i5-7500.
This diagram was arranged according to the result of the photo processing, and here the Ryzen 3 CPUs are well suited for the 1300X, which almost corresponds to the Core i5-7500. After overclocking, both the 1200 and 1300X achieved the 1500X-like performance.
The Ryzen 3 1200 was slightly faster than the G4560 in our video editing test, while the 1300X was between the i5-7500 and the i3-7350K – the higher clocked Core i3 CPU was the faster of the two. Overclocking has increased the performance of Ryzen 3 significantly, and we are now seeing Core i7-7700K-like performance in this review.
