Benchmarks Surface for AMD Ryzen 4700G, 4400G and 4200G Renoir APUs
This increase in CPU cores, of course, has implied a reduction in the area of the chip that’s dedicated to the integrated Vega graphics GPU – compute units have been reduced from the 3400G’s 11 down to 8 compute units on the Ryzen 7 4700G and 7 compute units on the 4400G – while the 4200G now makes do with just 6 Vega compute units. Clocks have been severely increased across the board to compensate the CU reduction, though – the aim is to achieve similar GPU performance using a smaller amount of semiconductor real-estate.
The 4700G’s 8 Vega CUs clocked at 2.1 GHz, as reported by the benchmark suite, achieve 4,301 points in the graphics and 23,392 points in the CPU score, which are respectively 6.65% and 22.3% higher than the 4400G’s 4,033 and 19,113 points (achieved with the same 8 Vega CUs clocked at a slower 1.9 GHz and with two fewer cores. The 4700G scores 20% and a whopping 70.6% higher than the 4200G’s in the graphics and physics tests respectively – which makes sense, considering the slower-clocked 6 Vega CUs (1.7 GHz) and 4 core / 8 thread configuration of the former. AMD’s 4000G series keeps the same 65 W TDp despite higher number of CPU cores and higher-clocked Vega cores, but the company will also have Ryzen 400=GE series which achieve a 35 W TDP, albeit at the cost of reduced CPU clocks (and likely GPU clocks as well).
_rogame, another well-known leaker, found two comparable system configurations running the Ryzen 4200G and 3200G, where the 4200G delivered 57% higher CPU performance, but 7% less GPU performance.
