Without any lack of official confirmation from AMD it's hard to assume this chip indeed lacks an igpu. Because the MAJOR selling point of Zen 4 was the fact that it finally has an iGPU, as claimed by AMD, so this new SKU means AMD is changing it's policy or their roadmap ?
Also, we have zero evidence that iGPU yields were poor, and/or the ZEN 4 CPUs had a high rate of failure to begin with. Why will AMD just COPY Intel's naming scheme from their book, is beyond me ? They could face a backlash if they do.
Just because Intel uses F in the nomenclature doesn't mean AMD will follow suit. Even if it DOES, they would be directly copying INTEL's naming scheme which makes little sense to me, TBH.
But anyway, chances are high that this CPU would most likely be an ASIA-only exclusive SKU, or maybe some OEMs may use this in their pre-built systems. Though, it would be good if this SKU launches for the DIY segment as well, but it's hard to come to any conclusion as of now. I'm not fully convinced.
Although, the Korean retailer claims this chip indeed doesn't pack an iGPU so its very similar to Intel's "F" chips, but we don't have any concrete evidence. Also, the original TWEET got deleted for no reason which raises more questions than answers.
If this indeed turns out to be true, then this chip could either be a defective "Raphael" single-CCD MCM with a disabled iGPU, or maybe this is based on the recently released 4nm Phoenix-2 "monolithic" silicon/die. Because, Phoenix-2 has a die size of 137 mm² and only features max 6 "Zen 4" CPU cores, and an iGPU with only 4 RDNA 3 CUs.
