AMD Ryzen 4000 Renoir Desktop APU Specifications Leaked

AMD's upcoming Ryzen 4000-series (codename Renoir) desktop APUs aren't available yet, but a recent leak claims to show specifications for engineering samples, which should still be near specs for the final product.

Similar to the mobile AMD Ryzen 4000 processors (codename Renoir), the desktop variants are expected to unify AMD's Zen 2 CPU and Vega GPU microarchitectures. The new APUs, which will come out of TSMC's 7nm FinFET stove, should arrive with the goodness of Zen 2. 

The specifications were leaked by German publication Igor's Lab the information doesn't clarify whether or not there is PCIe 4.0 support. It does, however, point to 12 potential Ryzen 4000-series APUs.

*Specifications are not confirmed.

From the leaked specification we can see that there are six chips of G series which have 65 TDP and other six are will be GE series that are sticking to low power 35 TDP with also lowered Clock cyclesAMD is accustomed to releasing Pro versions for its APUs, which would explain why there are two different OPNs (Ordering Part Numbers) with identical specifications for each model.

 According to the leaked information, the Six chips will come with 3-tier with  Quad-core, Hexa-core and Octa-core designs this suggests that AMD would, for the first time in its history, probably introduce the Ryzen 7 branding in an APU lineup.

For the sake of simplicity, let's treat the quad-core, hexa-core and octa-core parts as Ryzen 3, Ryzen 5 and Ryzen 7 SKUs.The Ryzen 7 chip seemingly features eight cores, 16 threads and 8MB of L3 cache. The Zen 2 cores were reportedly run with a 3.6 GHz base clock and 4.45 GHz boost clock. The iGPU appears to come with eight Vega Compute Units (CUs) clocked at 2,100 MHz. 

Although not confirmed yet, this configuration would be a step backwards in terms of CUs. The previous AMD Ryzen 5 3400G had up to 11 CUs, which were running at 1,400 MHz. The Ryzen 7's CUs operate at a 50% faster clock, however, so AMD might be trying to make up the CU deficit with higher clock speeds. 

The Ryzen 5 reportedly combines a six-core, 12-thread setup with 8MB of L3 cache as well. The leaked table points to a 3.7 GHz base clock and 4.3 GHz boost clock. The iGPU is down to seven CUs that top out at 1,900 MHz, only 200 MHz lower than the Ryzen 7's iGPU.

Lastly, the Ryzen 3 presumably flaunts a quad-core, eight-thread design that's complemented with 4MB of L3 cache. The processor sports a base and boost clock of 3.8 GHz and 4.1 GHz, respectively. 

AMD Ryzen 4000-Series GE APU Specifications*

OPN	Cores / Threads	Base / Boost Clock (GHz)	L2 Cache (MB)	L3 Cache (MB)	Compute Units	Graphics Frequency (MHz)	TDP (W)
100-000000149	8 / 16	3.10 / 4.35	4	8	8	2,000	35
100-000000152	8 / 16	3.10 / 4.35	4	8	8	2,000	35
100-000000150	6 / 12	3.30 / 4.25	3	8	7	1,900	35
100-000000153	6 / 12	3.30 / 4.25	3	8	7	1,900	35
100-000000151	4 / 8	3.50 / 4.10	2	4	6	1,700	35
100-000000154	4 / 8	3.50 / 4.10	2	4	6	1,700	35

*Specifications are not confirmed.

The GE-series consists of more energy-friendly versions of the regular SKUs. While they do essentially retain the core count and cache configurations, according to the leaked documents, they run at lower clock speeds to abide by the 35W target.

For the Ryzen 7, the difference in clock speeds seemingly comes down to 500 MHz on the base clock and 100 MHz on the boost clock. The iGPU on the GE model also shows a 100 MHz reduction.

The decline in the Ryzen 5 models isn't as drastic. The GE variant only seems to run with a 400 MHz and 50 MHz lower base and boost clocks, respectively. The iGPU remains untouched at 1,900 MHz.

Lastly, the Ryzen 3 SKUs received the best deal out of the lot. The GE version only shows a 300 MHz reduction on the base clock, while the boost clock stays the same. As expected, the iGPU continues to maintain the 1,700 MHz clock speed.

Now that these alleged specs are out. Stay tuned for more updates
