AMD’s Rumored 4700G APU Packs 8 Cores, Boosted Clock Speeds


AMD’s Ryzen Mobile CPUs hit the market to some fanfare earlier this year, delivering substantially improved overall performance over previous generation chips and very strong competition for Intel on the whole.

It’s been obvious that AMD would bring this APU family to desktop as well, but it looks like the CPU in question may be fairly aggressive. Rumors suggest that the Ryzen 4700G is an 8C/16T CPU with a base clock of 3.6GHz, a boost clock of 4.45GHz, 4MB of L2, 8MB of L3, and a 2.1GHz maximum GPU clock, all packed into a 65W TDP.

Could it be true? It could be. Grain of salt, etc. But a move like this isn’t crazy, relative to how AMD has been evolving the overall Ryzen product family.

Ever since Intel and AMD introduced on-die graphics, they’ve pursued very different strategies. Intel put on-die graphics on just about every CPU, outside of servers and the desktop HEDT family. The “KF” CPUs it now sells without graphics were only launched to improve yields during a critical CPU shortage. AMD, on the other hand, always reserved its on-die GPU for a limited number of CPUs. Ever since it launched Llano, AMD has pursued a two-tier strategy with a CPU-only desktop platform with a higher total number of cores as well as an APU strategy with fewer CPU cores but respectable on-die GPUs.

This rumor suggests that AMD could make graphics standard on all parts below the 16-core level. It’s not clear how much of a value-add this represents to modern users. APU graphics are unquestionably valuable for two reasons: You cannot lose access to a system simply because your GPU dies, and you can run multi-monitor configurations more readily if you have a built-in GPU. Relatively few people, however, find themselves in dire need of either capability on the regular.

Supposedly, the GPU onboard the Ryzen 7 4700G would be an 8-CU Vega chip with 512 cores in total, clocked at a blazing 2.1GHz. That’s incredibly fast for an onboard APU, even if clocking up that high can only make a limited amount of sense due to memory bandwidth limitations. The Ryzen 7 4700G will undoubtedly shine with high-speed memory — APUs always do — but the relatively high price of RAM as you move up the clock charts always makes this investment an uncertain proposition.

Depending on how AMD distributes and prices for the new Vega graphics core, these new APUs could be a noteworthy performance improvement on the old, especially for people who are primarily CPU-focused. AMD could also be planning a preemptive response to any changes Intel might make to its own desktop graphics with future CPU launches.
