To start, AMD is commencing a pair of low-power processors for the laptop market the Ryzen 7 2700U and the Ryzen 5 2500U. Both of these processors correlate four of AMD’s latest Zen cores, with some trivial differences, with AMD’s latest Vega graphics, into a single piece of silicon. These are both 15W processors, using the U-suffixed vocabulary that Intel has analyzed for its 15W parts. By receiving throughout a 15W TDP, AMD is proposing for the same range of thin and light records that are currently almost completely Intel-powered, while also using the Vega graphics architecture as an important selling point in gaming and collector workload acceleration. AMD has also gone into the part about a number of power-saving technologies that is has promoted and implemented to accommodate better battery life.
Both APUs will have four CPU cores and concurrent multi-threading, giving eight threads total. The rated base clock for the processors will be in the 2.0 GHz range, although AMD says that the typical all-core turbo will be extremely higher than this. CPU boost numbers are 3.8 GHz for the Ryzen 7 2700U and 3.6 GHz for the Ryzen 5 2500U, which sound very high for 15W processors but AMD has declared that this frequency sequence is more in the performance sweet spot for the processor design. Like its opponent, OEMs can use these processors in configurable TDP modes, which AMD countries are from 9W to 25W. We are under the supposition that these power modes do not change the numbers, but merely affect the turbo profile which we’ll discuss later.
The single silicon device has 11 Vega compute units onboard, of which the Ryzen 7 2700U will be able to use 10 of them, and the Ryzen 5 2500U will be able to use 8. These will be named ‘Vega 10’ and ‘Vega 8’ graphics individually. AMD does not provide the base rates for the graphics but does state that the greatest frequencies for the parts will be 1300 MHz and 1100 MHz respectively. One of AMD’s key argument points in our briefings was about the ability to shift power within the CPU and the GPU to keep the maximum production at all times.
