AMD is preparing to bring it to the desktop market at the end of the month Ryzen 8000G APU with integrated graphics RDNA3 for socket AM5. The four announced solutions, of which only three are intended for the consumer sector, provide for the two smaller models: Ryzen 5 8500G and Ryzen 3 8300Ga mixture of kernels Zen 4 e Zen 4c.
In the first case we have a total of 6 cores and 12 threads, a result of the union of 2 Zen 4 cores and 4 Zen 4c cores, while the 8300G model, aimed only at the OEM segment, has 4 cores and 8 threads offers, including 1 Zen core and 3 Zen 4c cores.
If from the perspective of the ISA, i.e. the supported instruction set, these cores are identical and therefore represent a difference to Intel's P-Core/E-Core project, there is one thing in common: Zen 4c cores operate at lower frequencies than Zen 4 cores.
AMD has published the pages of the various models with the full specifications on its website and from this it can be seen that the two cores of the 8500G and 8300G APUs work at different clocks.
In the case of8500G let's observe The Zen 4c cores have a base clock of 3.2 GHz and a boost clock of up to 3.7 GHzcompared to a base clock of 4.1GHz and a boost clock of up to 5GHz for the Zen 4 cores.
On the point related to Boost clock of Zen 4c coresAMD has placed an “i” – which stands for information – indicating: “The maximum frequency of Zen 4c cores. This frequency is only observed in certain processes which give priority to a single thread on the Zen 4c core. In normal operating mode, the Zen 4c's core frequency is lower and depends on several factors, including the number of threads running.
However, it is also stated on the page further generic basic clock datain the case of the Ryzen 5 8500G equals 3.5 GHz: that is the “Average effective base frequency of all cores“. You can see the same thing, with different clocks on the 8300G sidea quad-core with 8 threads, which is – at least currently – not intended for the consumer market.
In anticipation of the debut, we therefore know one more detail about the new proposals. In recent days we have learned more about the composition of the PCI Express lines, useful information for those who want to combine these APUs with a dedicated GPU (however small their importance), as well as the right memory to support the new ones Making APUs perform at their best.
