One of the parts that is not being talked about within what the Ryzen 7000 is being is its iGPU. It is true that it is merely testimonial to provide video and little else, which is AMD’s first attempt to have a CPU as complete as Intel’s, but… What happens if we overclock this GPU under RDNA 2? Well, what we can get is really surprising, since the overclocker Skatterbencher has managed nothing less than to increase its performance by 42%, taking it up to 3.1 GHz. Is it enough for gaming?
With only two CUs it is really complex to play, if not impossible, even very undemanding titles. AMD’s goal was to include a display controller that would lay the hardware foundation for new architectures to kick off the competition for iGPUs with their biggest rival. Does overclocking show us the path we will see in that future? Partly yes.
The overclock to the iGPU of a Ryzen 7000 surprises and for the better
Based on the fact that this iGPU at 1080p and at medium or low settings barely manages to push the games above 20 FPS, it was to be expected that it would go practically unnoticed after its corresponding analyzes. Their two CUs at 2,200 MHz they are insufficient for the required minimum, but… And if we raise 900 MHz? Well, everything changes a little for the better. For this reason, Skaterbencher with the help of Precision Boost Overdrive and GFX Curve Optimizer got down to work to raise the voltage of this iGPU of his Ryzen 7000 and test its overclock.
The voltage barely reaches 1 volt standardthe frequency exceeds 2 GHz and memory runs at 2.4 GHz stock. For this reason and with manual overclock to this iGPU of the Ryzen 7000 it achieved a quite important figure of 2.949 MHz on your first tryfor which he had to raise the voltage a twenty% until the 1.2V.
The consumption of this and the SoC went from 38.5 watts to 63.5 wattsi.e. almost a 65% increase which was also driven by a clock of 3.2 GHz in VRAM.
Frequency and voltage curve fitting did the rest
And that was how he was able to scale the remaining 150 MHz until he got the 3.1GHz finals, yes, with 1,395 voltswhich is almost a 40% increase in this section. What in principle does not make sense is that by increasing the voltage 20% more with respect to the previous overclock the consumption drops, to be precious, 2.8 watts until touching the 60.7W in total.
Given this, what has been achieved in terms of performance? Well, taking into account that the increase in frequencies for CUs has been of a 41% and 33.3% for VRAM, the performance improvement is uneven, as expected, but there have been improvements of up to a 41.67%specifically in Tomb Raider.
In the rest of the tests, the improvements are around an average increase of approximately 30% with some specific scores that have barely taken off. Likewise, in games and saving CS:GO, the iGPU is still unable to move titles like FFXV or the named Tomb Raider, it simply lacks muscle. What has been shown, however, shows that there is room for improvement in frequencies and that this iGPU is very capacious looking for the minimum and fair performance so as not to be a problem in temperatures and consumption in relation to the CPU cores.
As this will improve for the next processors, it is possible that we will see more CUs in their variants, especially laptops, which will have to do without so much power in Cores to bet a little more on integrated graphics, such as APUs. Dragon Range.
