Engineering samples of the AMD Ryzen 3 5300G and the Ryzen 7 5700G have been listed on eBay even though AMD hasn't hinted about the arrival of Cezanne desktop APUs yet. There are some shortcomings with these samples, but early benchmarks show decent leads over their corresponding Renoir parts and also the Intel Core i7-10700K.

So far, we have only come across a couple of AMD Cezanne desktop APU engineering sample (ES) leaks, but now they seem to have made their way to eBay for purchase. For now, the Ryzen 3 5300G and the Ryzen 7 5700G desktop APUs seem to be available. These are still ES, but we do get to know some specifications alongside a few early benchmarks.

The Cezanne APUs are listed on eBay by a seller named hugohk (Hugo on YouTube), who has also created videos showing the APUs in action (embedded below). 

AMD Ryzen 3 5300G

The AMD Ryzen 3 5300G ES is a Cezanne desktop APU that succeeds the Renoir Ryzen 3 4300G. This engineering sample, which carries an OPN code 100-000000262-30_Y, seems to have a base clock of 3.5 GHz and may probably boost up to 4.2 GHz. The seller also indicates that the Ryzen 3 5300G sports a Vega 8 iGPU, which is a welcome improvement over the Vega 6 found in the Ryzen 3 4300G. 

The Ryzen 3 5300G ES can be had from eBay for US$176.99, but there are a few shortcomings to be aware of. The Ryzen 3 5300G sample does not have any official graphics drivers as of now, and it may also have compatibility issues with most socket AM4 motherboards. However, X570 and B550 boards with the latest BIOS should be able to recognize this APU. The seller also mentions that he could source a working beta graphics driver, which would be provided to the buyer. PCIe Gen4, however, does not seem to work yet.

Hugo could do some benchmark testing after updating to the working graphics driver and compared the performance to a Ryzen 3 Pro 4350G. Overall, he observed a 10.4% and 7.9% improvement in CPU-Z single-core and multi-core, respectively. Cinebench R15 single was not run but multi-core showed a 16.6% uplift compared to the Ryzen 3 Pro 4350G.

Coming to gaming, the beta working driver did not enable sound but resulted in playable frame rates in Battlefield 4 and Battlefield 5 at 1080p low settings. The APU seems to perform well in stress testing as well with the temperatures hitting just 49 °C under load (ambient 23 °C) with a standard Wraith Prism cooler.

AMD Ryzen 7 5700G

We had already reported about the Ryzen 7 5700G (could even be a Ryzen 7 5750G) with OPN code 100-000000263-30_Y getting listed on eBay for US$499.99. This is the same ES that first surfaced on Chinese site QQ back in January. Much of the caveats detailed for the Ryzen 3 5300G apply for the Ryzen 7 5700G as well. The specifications are still not clear, but we do see up to a 4.6 GHz boost under 1.3 V and up to a 4.7 GHz boost when the voltage is increased to 1.425 V.

The Ryzen 7 5700G ES shows a 10.8% lead over the Ryzen 7 Pro 4750G Renoir part and a 11% lead over the Intel Core i7-10700K in CPU-Z multi-core. Similar results were also seen in Cinebench R15 multi-core with the Ryzen 7 5700G ES showing a 9.4% and 10.3% advantage over the Core i9-9900K and the Core i7-10700K, respectively and a 11% benefit over the Ryzen 7 Pro 4750G. 

The Ryzen 7 5700G offered playable frame rates in Battlefield 4 in 2K low and Battlefield 5 in 1080p low provided playable frame rates on the beta working driver for the integrated Vega 8 iGPU. Stress testing with a Wraith Prism cooler showed the processor hitting 65 °C in an ambient room temperature of 22 °C.

It must be reiterated that these are just engineering samples and the specifications are still likely not finalized, so there's still a lot of scope for performance improvement. AMD hasn't even hinted about Cezanne desktop APUs yet, so we do not have any information on a likely launch date. But if these very early benchmarks are anything to go by, we might see Cezanne desktop APUs take on Intel Comet Lake-S offerings in a highly competitive manner.
