AMD Ryzen 7 8700F & Ryzen 5 8400F Desktop APUs Tested: China-Exclusive, Lower Boost Clocks, Similar Performance

AMD's China-Exclusive Ryzen 7 8700F & Ryzen 5 8400F Desktop APUs for the AM5 socket have now been tested by motherboard vendor, JGINYUE.

A few weeks back, AMD announced that it was preparing two new SKUs for the Chinese market, the Ryzen 7 8700F & the Ryzen 5 8400F. Details regarding these SKUs were limited but now we know the full specifications of both chips which are essentially more cost-effective solutions to attract a mainstream and budget gaming market.

Starting with the specifications, the AMD Ryzen 7 8700F APU features 8 cores and 16 threads based on the Zen 4 core architecture. It has a base clock of 4.1 GHz and a boost clock of 5.05 GHz which is both slower in base and boost versus the Ryzen 7 8700G (-0.05 GHz Boost / -0.10 GHz Base). It has a total of 16 MB of L3 cache and lacks the RDNA 3 iGPU.

Similarly, the AMD Ryzen 5 8400F features 6 cores and 12 threads based on the Zen 4 architecture. It features a base clock of 4.2 GHz and a boost clock of 4.75 GHz (-0.25 GHz Boost / +0.1 GHz Base). The chip also features 16 MB of L3 cache with 6 MB L2 cache and doesn't feature any RDNA 3 iGPU. As for the TDP, both chips are configured at 65W.

In terms of performance, the AMD Ryzen 7 8700F and Ryzen 5 8400F offer very similar numbers versus the Ryzen 7 8700G and Ryzen 5 7500F. The Ryzen 7 8700F is around 2% slower at max and differences are only seen in multi-threaded tests. The Ryzen 5 8400F also keeps up with the Ryzen 5 7500F in single-threaded tests but comes down to 11% slower in multi-threading tests since the Ryzen 7000 series offers better performance through their chiplet architecture versus the SoC lay-out on the APUs. The Ryzen 7000 CPUs also have twice the L3 cache.

Prices for either chip aren't mentioned but we expect them to be slightly lower than the Ryzen 7 8700G and Ryzen 5 8500G which will make them a good deal for users upgrading to the new AM5 platforms.
