AMD Ryzen 7000’s Tiny RDNA2 GPU Overclocked to 3.1 GHz

AMD’s newest Ryzen 7000 collection processors for desktop computer systems based mostly on the Zen 4 microarchitecture comprise a small RDNA-based graphics processing unit inside their I/O die (IOD). This GPU just isn’t designed for gaming, however SkatterBencher Within the case of AMD’s Ryzen 7900 processor, which improves its efficiency by about 42% (by way of VideoCardz). This does not imply that GPU all of the sudden turns into a viable gaming answer, however a minimum of efficiency will acquire.

AMD’s Ryzen 7000 collection ‘Raphael’ desktop CPUs combine an RDNA 2-based GPU with 128 stream processors and a pair of CUs of their IOD. This graphics answer operates at as much as 2.20 GHz and offers roughly 0.563 FP32 TFLOPS of computing throughput; that is akin to a high-end graphics card from 2007 (for instance, the ATI Radeon HD 2900 XT). That is by far not sufficient to get first rate framerates in a contemporary sport. Nonetheless, this GPU can show graphics and play some movies. It may also be overclocked.

Overclocking the built-in GPU just isn’t a trivial activity. On the one hand, AMD’s Agesa helps overclocking the iGPU, however to squeeze all of the potential efficiency of this graphics processor, you want to enhance the voltages and energy limits, in addition to play with AMD’s Precision Increase Overdrive settings.

In the meantime, even a considerably elevated Precision Increase Overdrive energy price range by itself will not be a big enchancment for the onboard GPU as a result of it is a small, low-end graphics answer that is not meant to carry out. Subsequently, it makes extra sense to manually enhance the VDDCR_SOC voltage and VDDCR_GFX voltage to supply extra energy to the built-in GPU.

By default, the GPU runs at 2.20 GHz at 0.997V, however when the voltage is elevated to 1.2V, the GPU can attain 2949 MHz. Adjusting the voltage/frequency curvature to 1.395V helps enhance the GPU frequency to three.10 GHz. In the meantime, this will increase SoC energy from about 38.5 W by default to 60.7 W, which suggests elevated cooling necessities.

Efficiency-wise, this offers as much as 42.5% extra efficiency in video games like Tomb Raider, however at 17 frames per second, the title stays unplayable. It additionally permits to run a ray tracing benchmark on the onboard GPU which doesn’t run by default. Nonetheless, even such excessive overclocking would not present a big efficiency enhance in plenty of artificial benchmarks, probably as a consequence of different limitations.

Overclocking the built-in RDNA 2-based GPU is a doable factor, though it would not appear to deliver any real-world fruition. Additionally, it appears that evidently overclocking its built-in GPUs is simpler than overclocking discrete GPUs, as AMD doesn’t enable adjustment of the voltage/frequency curve on discrete RDNA 3 graphics playing cards.
