Ryzen 7000 APUs for notebooks will feature integrated GPUs based on the RDNA2 architecture. As our regular readers will remember, AMD has already made the leap Architecture of RDNA2 in integrated graphics with APU Ryzen 6000 Mobile, which had a configuration of up to 768 shaders and could reach a speed of 2.4 GHz in turbo mode.

Despite the fact that both will share the same basic architecture, the integrated GPUs that will use the Ryzen 7000 APU for notebooks will have some important changes that will generally allow for significant performance improvements. The first thing we need to be clear about is that these GPUs they will not have infinite cachethis means they will lack a dedicated L3 cache, which is understandable given the space it would take up at the silicon level.

Second, AMD is going to double the L0 cache, used for vector data, will range from 16 KB to 32 KB per compute unit. The GL1 data cache will also be doubled, increasing from 128 KB to 256 KB, and the L2 cache, increasing from 128 KB to 256 KB on the SA (Shader Array) and 512 KB on the SE (Shader Engine).

We still don’t have details on the specific specs that AMD will use in these new integrated GPUs, but the latest information we’ve seen so far is promising as it suggests that Sunnyvale could create a top-of-the-line integrated solution that doesn’t have nothing more and nothing less than 1,536 shaders, 96 texture units and 32 raster units, plus 24 units to speed up ray tracing. This integrated GPU relies on DDR5 system memory (using it as VRAM) and communicates with it via a 128-bit bus (if configured as dual channel).

Although in terms of raw performance, the RDNA2 iGPU of the upcoming Ryzen 7000 mobile APUs will be higher than the GeForce GTX 1060 and Radeon RX 6500 XT, its gaming performance could be significantly lower, because of the impact your lower bandwidth will haveand also the absence of that L3 cache, which precisely helps to achieve peaks in bandwidth and acts as a storage system for data that changes more often and takes up less space, such as lighting.

In any case, the important thing about all of this is that AMD seems to be making such a big leap with the Ryzen 7000 APU laptop iGPUs that it could eventually become viable to play, in most cases, at 1080p. with high quality or very high for current titles without a dedicated graphics card.
