AMD's Flagship Ryzen 4000 'Renoir' CPU has been spotted, the Ryzen 9 4900U, which will feature faster specifications than the Ryzen 7 4800U. While both processors feature the same core config, it's the Ryzen 9 4900U which has the highest clocks of the two offerings and will be embedded in more powerful laptop designs, even if it is a 15W chip.

AMD Ryzen 9 4900U 'Renoir' CPU With 8 Cores, Faster Vega Graphics & Up To 4.3 GHz Clocks Spotted

So far, AMD has officially announced the Ryzen 7 4800U as the fastest 15W Renoir chip but we had seen systems from various manufacturers which listed the Ryzen 9 4900U. The CPU has now been spotted in various online databases by TUM_APISAK, mainly 3DMark and UserBenchmark. It looks like AMD Ryzen 9 4900U, like the Ryzen 9 4900H, would keep the same core config as the Ryzen 7 SKU but take it up a notch by boosting the clock speeds in a higher binned package.

Coming to the specifications, we are looking at 8 Zen 2 cores, 16 threads and a total of 20 MB cache on the Ryzen 9 4900U. The stock core clock is reported at 1.8 GHz which is the same as the Ryzen 7 4800U but its the boost clock of this chip which has received a slight bump. It is speculated that the Ryzen 9 4900U would be able to clock up to 4.3 GHz, a 100 MHz bump over the Ryzen 7 4800U and the Vega 8 graphics chip on this processor may also get a slight bump in clock to 1800 MHz versus the 1750 MHz frequency on the Ryzen 7 4800U.

With that said, the early samples that have been spotted aren't final yet and the average reported boost clock at UserBenchmark is reported at 2.35 GHz while boost frequency isn't working over in 3DMark as the chip has a turbo core clock of 1.4 GHz, lower than its base frequency of 1.8 GHz. It looks like AMD will introduce the Ryzen 9 4900U in the coming months in faster laptop design that still focuses on low-power operations. The better bin would enable slightly better performance for the same power input.
