If there were any doubts that the AMD Ryzen 7 4700 (opens in new tab)G is really in the works, VideoCardz (opens in new tab) just shook things up. The site claims to have posted a retail sample of the chip with an anonymous source saying it shouldn't be long until AMD's Ryzen 4000-series (codename Renoir) desktop APUs (opens in new tab) hit the shelves.
Much like AMD's other processors, Renoir is expected show a move to TSMC's 7nm FinFET process node. The new APUs should retain the Vega microarchitecture on the graphics end, but also leverage AMD's most recent Zen 2 microarchitecture. Other anticipated improvements include higher core (opens in new tab) counts, faster clock speeds (opens in new tab), improved iGPU frequencies and native support for DDR4-3200 RAM (opens in new tab).
We haven't heard about PCIe (opens in new tab) 4.0 support yet. On the other hand, Renoir is slated to dwell on the AM4 CPU socket, However, a motherboard firmware (opens in new tab) update will likely be required.
The Ryzen 7 4700G in the photograph pridefully carries the 100-000000146 OPN (ordering part number), which coincides with one of the previously leaked Ryzen APUs (opens in new tab).
We wouldn't be surprised to see the Ryzen 7 4700G arrive with eight cores and 16 threads (opens in new tab) in order to double the counts on the AMD Ryzen 5 3400G (opens in new tab), the flagship of the previous generation of APUs.

*Specifications are not confirmed.
Assuming that AMD didn't tweak the specifications too much, we could see the Ryzen 7 4700G with a 3.6 GHz base clock and 4.45 GHz boost clock. It's probable that the octa-core APU might end up with 4MB and 8MB of L2 and L3 cache (opens in new tab), respectively.
The Ryzen 7 4700G is rumored to come with eight Vega Compute Units (CUs), which would amount to a total of 512 Stream Processors (SPs). That's three fewer CUs than the Ryzen 5 3500G. However, Ryzen 5 3400G's iGPU maxes out at 1,400 MHz, and the Ryzen 7 4700G's iGPU reportedly scales up to 2,100 MHz. It will be interesting to see if a 50% uplift in iGPU frequency can balance out losing three CUs.
AMD has been offering its APUs at a 65W TDP (thermal design power) for a while now, so we don't see that changing with Renoir. AMD tends to later roll out GE-series variants adhering to a 35W TDP for consumers that prioritize energy-efficiency over performance.
If we look at the competition, the Intel Core i7-10700 (opens in new tab) shares a similar core count and TDP as what the Ryzen 7 4700G is rumored to have. Intel's contender features a 2.9 GHz base clock and 4.8 GHz boost clock and comes with 16MB of L3 cache. The Core i7-10700 carries the Intel UHD Graphics 630 (opens in new tab) iGPU with 24 Execution Units (EUs) with a boost frequency of 1,200 MHz.
The Core i7-10700 has a $323 MSRP and currently competes with the $329 AMD Ryzen 7 3700X (opens in new tab). We expect the Ryzen 7 4700G to cheaper at $200-$250.
