AMD "Cezanne" APU Spotted: Retains Renoir's iGPU, Updates CPU to "Zen 3"
AMD's 5th Generation Ryzen "Cezanne" APU sprung up on SiSoft SANDRA database, with big hints as to the areas where the company could innovate next. Apparently, "Cezanne" is a very similar silicon to "Renoir." It appears to feature the same iGPU solution, based on the "Vega" architecture. We're now learning that the iGPU even has the same core configuration, with up to 512 stream processors, and a likely bump in iGPU engine clocks over the Ryzen 4000 "Renoir" chips.
Much of the innovation is with the CPU component. Although the CPU core count is not yet known, the company is deploying its "Zen 3" microarchitecture, which sees all cores on the silicon sharing a large common slab of L3 cache. The "Vega" based iGPU should still perform better than the solution on "Renoir," as it's assisted by higher engine clocks, and possibly a higher IPC CPU component. In the SANDRA screenshot, the iGPU was shown bearing 1.85 GHz engine clocks, which amounts to a 100 MHz speed-bump compared to the engine clocks of the Ryzen 4000H and 4000U.

Vega iGPU forever lol.
For most people, they just want their APU to be low power, that their video decode without using too much cpu and that's it. Gaming on APU is a thing, but it's not big enough of a thing to justify investing heavily into APU performance.
I would still like to be able to buy an APU running 1080p games high details at 60 fps with a 35 watt tdp but that is not going to happen soon.
Oh well, you win some you lose some. Tune in to pretty much any media in 26 hours to know more.
AMD, same generation-to-generation as far as I can tell (I straight up don't follow Intel at all) musters literally half the performance.

k :rolleyes:
Anyway, that screenshot shows DDR3 and a very low memory bandwidth that does not make sense.
On lower clocks, CU's and all that its a very efficient GPU. Only bottleneck is its memory bandwidth.
Or maybe it's just "if it ain't broke don't fix it" mantra applied to save on some R&D?
