AMD's Ryzen 8000 CPU with Navi 3.5 graphics could kill low-end GPUs
A new roadmap from AMD confirms both its next-gen Ryzen 8000 CPUs with Zen 5 technology and an updated «Navi 3.5» graphics architecture will arrive next year. Some rumours suggest Navi 3.5 could enable integrated graphics with performance on par with an Nvidia RTX 3070.
AMD has mentioned Zen 5 previously, but this is the first mention of Ryzen 8000 (via Videocardz). It's also the first official listing of a new Navi 3.5 graphics architecture.
The official roadmap doesn't go into any details regards Navi 3.5. But a recent Twitter post from serial leaker Kepler_L2 suggests that it's largely the RDNA 3 architecture with a few bits from RDNA 4.
More specifically, it's said to have revised shader ALUs with support for new FP32 instructions and improvements to the geometry engine, but not new RDNA 4 scheduler and improved RT cores. What does all that mean for actual performance? Frankly, who knows.
Arguably the bigger news associated with this new Navi 3.5 graphics is that it's rumoured by several sources including RedGamingTech to feature in a new mega APU variously referred to as Strix Halo or Sarlak that we've touched on previously. What everyone agrees on is that the integrated graphics in this new chip will top out at 40 Compute Units.
That's the same as a current AMD Radeon RX 6700 XT and translates into 2,560 shaders or stream processors. The rumours indicate that graphics performance will be on par with an Nvidia RTX 3070. If true, that would be stellar for an integrated graphics solution, far faster than anything previously seen.
Of course, one area where integrated graphics have always struggled is memory bandwidth, what with both the CPU cores and the graphics sharing a memory controller and that controller
