AMD Ryzen 9 4900U APU gets past the rumor stage by making a first appearance on UserBenchmark
A couple of months ago we reported on the rumor of the existence of an AMD Ryzen 9 4900U APU, which was sparked by a datasheet for a Lenovo Yoga Slim that listed the Ryzen 9 4900U as its processor. However, since then this particular APU seems to have slipped back into the shadows, until Tum Apisak recently spotted it on UserBenchmark.
The processor is actually listed as “AMD Ryzen 9 4900U Graphics” on the UserBenchmark database, which reveals it is unsurprisingly an 8-core, 16-thread part (FP6 socket). A base clock of 1.8 GHz is mentioned that would put the Ryzen 9 4900U on the same base footing as the Ryzen 7 4800U. An average turbo rate of 2.35 GHz is recorded, but it has been speculated the turbo could reach 4.3 GHz, which would be slightly more than the Ryzen 7 4800U’s 4.2 GHz boost. AMD’s 4000U series features APUs with low TDPs of 10-25 W.
The UserBenchmark results for the Ryzen 9 4900U in the AMD Ted3-RN system aren’t all spectacular, although a 1-core score of 136 points and a 2-core score of 198 points are actually very good. No doubt there will be higher scores for the Renoir APU once any driver issues and system problems have been worked out. It seems like there is going to be a Ryzen 9 representative for the AMD 4000U series after all.
