What appears to be a desktop AMD Ryzen 4000-series APU has surfaced courtesy of an Ashes of the Singularity benchmark. Although unconfirmed by AMD, this may be the clearest indication yet about the company’s Renoir desktop APU plans.
The benchmark itself first popped up via an entry on UserBenchmark as an engineering sample before once again appearing on the AOTS benchmark, as explained above.
The benchmark points to a high-performance AMD Ryzen 7 4700 G with eight cores and 16 threads geared for the AM4 socket armed with Radeon graphics, although it was paired with an AMD Radeon RX 5700 XT and 15747 MB (read 16 GB) of DDR4 RAM in this instance. Unfortunately, the test is very much graphically focused, so there are no performance results for the CPU itself, but it still appears to confirm that one of the desktop APU’s is planning is indeed the Ryzen 7 4700G.
Upon discovery of the AMD Ryzen 4700G CPU, known leaker _rogame jumped in to suggest the CPU will feature 8 Compute Units with a clock speed of 1750 MHz. This would put it on par with AMD Ryzen 9 4900HS for GPU clock rates. Compared to the mobile versions of the Ryzen 4000-series, the desktop models will be able to tap into a higher TDP count to provide extra headroom and, consequently, higher performance on the integrated GPU.
The earlier engineering sample leaks pointed to a base clock speed of 3.0 GHz, and a boost clock speed of close to 4.0 GHz, although we can safely assume the final product clock speeds will be markedly higher. This is mainly due to the use of the Zen 2 architecture, which will not only offer a higher core count, but these will also be faster by default suggesting a significant performance increase over the existing Zen+ cores currently in circulation.
As for when we can expect to hear some official news from AMD, July seems like the best bet based on rumors and information from industry insiders.
