Gigabyte has listed an unannounced AMD Ryzen 5 5700 APU based on the "Cezanne" silicon which doesn't feature an integrated GPU.
AMD Ryzen 7 5700 APU Features 8 Zen 3 Cores But Lacks The Vega iGPU, Aiming Budget PCs?
This is the first time the APU has surfaced online. The APU appeared in the "CPU Support" section of Gigabyte's X570 AORUS XTREME.
Diving into the specifications, the AMD Ryzen 5 5700 will feature 8 cores and 16 threads, a base clock of 3.7 GHz, and a boost clock of up to 4.6 GHz. Moreover, the processor has an L2 cache of 4MB and an L3 cache of 16MB, which is comparatively lower than the Ryzen 7 5700X since APUs utilize a monolithic design which is different than the chiplet design used by the standard Ryzen CPUs.
The AMD Ryzen 5 5700 APU features a similar TDP to its counterparts with a rating of 65W. One important thing to note is that the CPU is at A0 stepping, meaning that the chip is probably an engineering sample, and there may be some changes before final production. The specific processor is yet to appear on other motherboard vendors but Gigabyte should know more since they have it fully listed on their support page.
A likely conclusion is that AMD might be working on some budget-tier chips for its AM4 platform to move some remaining Zen 3 inventory. The APU can be a nice option if priced around the $120 to $150 US range, making it a very decent option for budget PC builders who can get an AM4 board at a sub-$100 US price point. AMD's AM4 motherboards do offer great designs in the sub-$100 range versus the newer AMD A620 offerings, most of which even lack a basic VRM heatsink. There are no further details regarding the pricing and availability of the processor, & the company is yet to make any official announcement.
