AMD Ryzen 4000 “Renoir” desktop APUs have quite a month in the Twitterverse. First, an unidentified desktop Renoir APU was spotted by TUM_APISAK on UserBenchmark indicating 8 cores, 16 wires, and a 3GHz base clock. And now, tipster @_rogame has leaked another chip with the Ryzen 7 4700G moniker.
Spotted from an axis of the Singularity benchmark, the Ryzen 7 4700G appears to have the same 8 cores and 16 wires as the previous APU, although we urge you to take this with a grain of salt. If this processor is real, it is expected to use the same Zen 2 architecture and 7 nm process that has made the Renoir mobile chips an amazing success. More importantly, it could double the number of cores on the current Ryzen 3000 APU line and its flagship, the Ryzen 5 3400G, which has only four cores.
UserBenchmark has seen fake entries before, so this is hardly proof that an 8-core, 16-wire Renoir desktop APU is definitely on its way. However, it is worth noting that AMD’s Ryzen 7 chips typically sport 8 cores, so if this rumored APU has in fact 8 cores, the name is definitely appropriate.
If the AMD Ryzen 7 4700G is real and on the go, it would be the very first APU to carry the Ryzen 7 branding. About the Ryzen 7 4700G unfortunately not much is revealed in this leak. But that hasn’t stopped anyone from speculating yet.
As reported by Tom’s Hardware, if this chip and the previously leaked desktop Renoir APU are actually one and the same, the Ryzen 7 4700G will have a 3GHz base clock, with a 3.95GHz boost. On the other hand, _rogame has argued that two 8-core Renoir APUs are currently being tested, one with a 3GHz base, the other runs on 3.5GHz.
In any case, these are decent numbers that could potentially be higher in the final production units. Tom’s Hardware reports the processor to support DDR4-3200 memory modules from the box but may not support PCIe 4.0 because Renoir mobile processors only support PCIe 3.0. Still, the Ryzen 3000 desktop chips are on the PCIe 4.0 interface, making it also possible to chase Renoir’s desktop APUs.
Furthermore, it is speculated that the Ryzen 7 4700G could take 9 4900H after the iGPU design of the Ryzen, giving it eight Compute Units (CU’s) and up to 512 Stream Processors (SP’s). Since the current flagship Ryzen 5 3400G has up to 11 CU’s, this could be a downgrade. However, AMD can compensate for this with a higher graphics clock.
Of course, nothing is known about pricing yet. But since the Ryzen 5 3400G sells for $149 (£139, AU$240), the price tag on Ryzen 7 4700G – again, if it exists – is expected to remain competitive, especially with AMD’s ethos of offering powerful components for less than the price of the competition.
