AMD is indeed bringing the Ryzen 7 8700F and Ryzen 5 8400F desktop processors to the retail PIB channel. Both these processors are based on the 4 nm "Hawk Point" or "Phoenix 2" silicon, but with their iGPU disabled, hence the "F" in the model name. Company slides related to the two were leaked to the web. The processors feature CPU cores based on the "Zen 4" microarchitecture, and are built in the Socket AM5 package.

The Ryzen 7 8700F features the 8-core/16-thread "Zen 4" CPU that the 8700G, but with lower CPU clock speeds of up to 5.00 GHz boost (compared to up to 5.10 GHz for the 8700G). Although its iGPU is disabled, its NPU isn't. The Ryzen AI NPU offers 16 AI TOPS performance. The processor retains the 65 W TDP of the 8700G. Moving on to the 8400G, and here we see the processor being based on the "Phoenix 2" silicon, with 6 CPU cores. Two of these are "Zen 4," and can reach the processor's 4.70 GHz maximum boost frequency; while the other four are "Zen 4c," and operate at lower clock speeds. The chip physically lacks an NPU, and its iGPU is disabled. It still has 65 W TDP to feed its CPU cores. In their retail packages, both processors include a Wraith Stealth cooling solution that's meant for 65 W TDP processors.
 
In terms of performance, AMD claims that the Ryzen 7 8700F offers gaming performance that's anywhere between 10% to 24% higher than the Intel Core i5-14400F in the six game tests and six productivity tests it used. The 8400F, on the other hand, offers anywhere between 1% to 14% higher gaming performance than the Core i5-13400F, AMD claims.

AMD hasn't officially launched these chips, but a launch could be imminent. We expect the two to be priced significantly cheaper than the 8700G and 8500G, respectively.
 
Should be good chips at a good price.
