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.

so the 8700f would be a 7700 or 7700x in terms of performance minus the npu?

I don't think so. 16MB APU vs 32MB CCD L3 (or earlier 8MB vs 16MB) has made a consistently real difference on APU CPU gaming perf in like the past 4 generations.

8700G and 8600G weren't amazingly competitive with the chiplet Zen 4 parts in gaming perf. These are no different. They need to be priced accordingly.

Should have upped the clocks in lieu of the iGPU IMO. Why would I want a gimped 7700 sans iGPU, with half the cache, it will never be cheap enough to make it the better choice.
 
So, looks like the competition is back and business as usual with funny naming and comparisons in slides.
8700F and 14700F, 8400F and 14400F.
8700F vs 14400F, 8400F vs 13400F. I would assume these are reasoned by pricing.
 
Old news! @Vayra86 you already got the unlocked 7 8700K one!
 
Eh. AMD should leave the iGPU enabled, even if in a minimum configuration. Just like in processors with I/O die. It wouldn't hurt the sales of 8700G and 8600G chips, which will never be sold in great numbers anyway.
 
So CPUs are like fashion now. Old is new again! Ha
It's surprising to see how few aesthetically looking integers between 1 and 14900 exist.

I would wager these chips are being made from CPU dies that have defective iGPU portions, to use those dies up instead of throwing them away.

Maybe just maybe amd glued together a bunch of coffee lakes though. All those failed delids probably

Sure, chips with defects in the display engine and other common parts would be unusable. But most of iGPU silicon area consists of six dual CUs. A manufacturing defect that takes out the entire iGPU is much less probable than a defect that just reduces the number of usable CUs (and/or their maximum clock).

No, the 8700F has lower boost clock compared to the 7700 (5050Mhz vs. 5350Mhz) don't have Gen5 PCI-Express support and only got 20 PCI-Express lanes compared to 24.
The 8700F nothing more than a 8700G APU without the IGP.

Also, half the L3 Cache.
