The Ryzen 5000 series has achieved a huge leap in performance with the new Zen3 architecture alone, and even single-core performance and gaming performance have finally overtaken Intel, which has little advantage. So, 7nm process unchanged, Rye Dragon 5000 series of power performance? Here’s a look at AnandTech’s special tests.
AnandTech’s testing is very detailed, including the overall and each core scenario.
As shown in the figure above, the red and orange systems represent the active core, the green system represents the idle core, the horizontal axis represents the active core opening gradually increased, the number axis represents the power consumption of each core, and the bottom is marked with the core power consumption (Cores), the overall power consumption (Package), and the corresponding frequency.
Among them, the core power consumption only contains different core, one, two or three levels of cache power consumption, the overall power consumption also includes IO Die, small chip communication, CPU and small chip communication, PCIe controller, memory controller.
Combined with this diagram, it is more obvious that the Rye 9 5950X is changing with the increased power consumption of the active core, with two particularly noteworthy points.
First of all, the power opening 8-10 cores is to reach the maximum value of 135-136W, at this time the core power consumption of about 115W, and then slowly decline, 16 cores when fully open the overall power consumption of 119W, the full core frequency of 3775MHz.
Second, when the active core changes from 4 to 5, the overall power consumption is reduced by 4W, at which point the frequency is reduced from 4725MHz to 4675MHz, which is not much, but the voltage is significantly reduced from 1.38V to 1.31V, while the non-core power consumption is increased from 16W to 21W.
The exact cause is unknown, but none of the other three Rye Terrion 5000s were tested for this phenomenon, and it is not known whether it was a test problem or a motherboard or BIOS relationship.
The maximum power consumption of the Rye 9 5950X in the Agisoft Photoscan image editing test and the y-Cruncher calculation test is around 130W, roughly in the 120-140W range.
The maximum power consumption of the Rye 9 5900X is 142W when the 8 cores are turned on, at which point the core power consumption is 106W, the overall power consumption at the 12 cores is 129W and the full core frequency is 4150MHz.
The Rye Dragon 7 5800X with a single CCD is simple, with a maximum power consumption of 131W and a frequency of 4450MHz when the 8 core is fully open.
The Rye 5 5600X 6 core consumes up to 76W when fully open and has a frequency of 4450MHz.
Finally, peak power consumption.
The AMD Ryron processor has a setting called Package Power Tracking/PPT, and the 105W thermal design power model is set at 142W, i.e. the actual power consumption of the roaster will not exceed this value, while for the 65W thermal design power model, the PPT limit is 88W.
Both generations of the Rye Dragon x900X/x800X series of high-end models have peak power consumption in the early 140W, the Rye Dragon 9 5950X/5900X are standard 142W, very dead card, but the Ryron 5 5600X only ran out 76W.
Intel, for its part, can completely free itself without similar restrictions, with the i9-10900K exceeding 250W and the i7-10850K reaching 265W.
