If there were any doubts that the AMD Ryzen 7 4700G is really in the works, VideoCardz 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 hit the shelves.
We haven't heard about PCIe 4.0 support yet. On the other hand, Renoir is slated to dwell on the AM4 CPU socket, However, a motherboard firmware 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.
We wouldn't be surprised to see the Ryzen 7 4700G arrive with eight cores and 16 threads in order to double the counts on the AMD Ryzen 5 3400G, the flagship of the previous generation of APUs.
AMD Ryzen 4000-Series Renoir Specifications*
| OPN | Cores / Threads | Base / Boost Clock (GHz) | L2 Cache (MB) | L3 Cache (MB) | Compute Units | Graphics Frequency (MHz) | TDP (W) |
|---|---|---|---|---|---|---|---|
| 100-000000145 | 8 / 16 | 3.60 / 4.45 | 4 | 8 | 8 | 2,100 | 65 |
| 100-000000146 | 8 / 16 | 3.60 / 4.45 | 4 | 8 | 8 | 2,100 | 65 |
| 100-000000143 | 6 / 12 | 3.70 / 4.30 | 3 | 8 | 7 | 1,900 | 65 |
| 100-000000147 | 6 / 12 | 3.70 / 4.30 | 3 | 8 | 7 | 1,900 | 65 |
| 100-000000144 | 4 / 8 | 3.80 / 4.10 | 2 | 4 | 6 | 1,700 | 65 |
| 100-000000148 | 4 / 8 | 3.80 / 4.10 | 2 | 4 | 6 | 1,700 | 65 |
*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, 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 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 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. We expect the Ryzen 7 4700G to cheaper at $200-$250.
