From this famous twitter user@TUM_APISAKAccording to the screenshot, there should be a product with 8 Cu units in the next generation of Renoir APU, and its core frequency of GPU will be as high as 1.75ghz, which is much higher than the 1200 / 1250mhz used by ryzen 33200, which also has 8 Cu units, and this should make its final performance much better. In terms of memory support, it is still dual channel DDR4, but it can not be concluded that Renoir will not support lpddr4x memory with higher bandwidth.
On the existing radeon RX 5700 series, the GPU operates at a very high frequency, and 1.75ghz is not too hard for it. This part is brought by architecture optimization, but the process bonus should be more obvious, so it's hard to say how the frequency performance of the Vega core that could not run up the original frequency would be after changing a process. After all, the Vega 20 core on the same 7Nm based radeon VII can run up to 1.75ghz at the highest.
According to the previousnewsThe new Renoir APU can be up to the Vega core of the 15-group CU unit, and at least one APU using the 12-group CU can be said to have been identified. The next generation of APU is the most likely to have 8 Zen 2 cores, a complete Zen 2 CCD, and it looks like its performance will be strong, at least as much as now on the Zen/ Vega-based APU.
