We all know that AMD is very professional to make quality APUs, being the first company to start this feature. Its Ryzen APUs are quite famous among budget gamers who get decent frame rates in games by using these inbuilt Vega graphics.
When AMD launched the Ryzen 3000 CPUs, it also launched the second generation of Ryzen CPUs with integrated Vega graphics. These APUs were built on Zen+ architecture, possessing some minor improvements over the last-gen, what we were looking for was the 7nm Renoir APUs with Vega graphics.
So, according to prolific tech leaker Komachi, AMD’s upcoming Renoir Zen2 APUs could feature a Vega 12 iGPU and it is also being speculated that a Vega 15 iGPU is also highly probable. Though previously it was speculated that these APUs would be launching in November, now it seems that we have to wait until CES 2020.
Komachi on Twitter did identify several Renoir listings with B12 in the nomenclature indicating a 12 Compute Units iGPU. As the architecture is based on 7nm process, it does make sense more space is available in the APU to stack some more Compute units of Vega graphics, but number of cores remains unclear.
When Vega 12 is mostly expected to make its debut in the iGPU segment, hardware enthusiast Locuza even feels that Vega 13 or even a Vega 15 configuration can also be spotted.
Comparing the Vega CUs and their caches, Locuza speculates that the Vega 13 might have a 3+3+3+3+1 CU configuration with each CU cluster featuring 32 KB L1 instruction cache and 16 KB constant cache. Or there could be a more probable 3+3+3+2+2 config, on the other hand, the Vega 15 could be seen with a 3+3+3+3+3 configuration.
Clinging on to the Vega graphics with 7nm Renoir APUs, AMD might be reserving the Navi iGPU for Zen 2+ instead. This could be possible as AMD might not have enough time to figure out 7nm Navi for the Zen 2 based Ryzen 4000 Renoir APUs.
Also, if everything goes as expected, then the Renoir APUs can possibly beat the Intel Ice Lake Iris Plus G7 graphics and also eclipse the newer NVIDIA GeForce MX250 graphics, which eventually depends more on both the memory implementation and available bandwidth.
