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. That includes native support for DDR4-3200 RAM sticks. 

German publication Igor's Lab said it received confidential documents that reportedly detail specifications for the upcoming chips. The leaked specifications don't clarify whether or not there is PCIe 4.0 support. It does, however, point to 12 potential Ryzen 4000-series APUs. 

Six of the chips are likely G-series, adhering to a 65W TDP (thermal design power), while the remaining six are probably the GE-series, which sticks to a more conservative 35W envelope. AMD 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 desktop Renoir will come in three tiers with chips rocking quad-core, hexa-core and octa-core designs. This suggests that AMD would, for the first time in the its history, probably introduce the Ryzen 7 branding in an APU lineup. There's already some evidence supporting that theory. An AMD Ryzen 7 4700G was recently spotted in a benchmark submission. 

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 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 backward 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. On the graphics end, the Ryzen 3 relies on six CUs at 1,700 MHz.

100-0000001544 / 83.50 / 4.102461,70035

*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 on 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, all we need is a launch date.

    I am actually looking forward to AMD reducing the price of the current Ryzen 5 3400G with the release of desktop versions of Renoir. While the CPU is slower using the Zen+ chips, the Vega 11 is still quite formidable vs the 4c/8t Renoir Vega 6. Even with the significant increase in clockspeed, I doubt it can keep up with the difference of 5 CUs.

    One thing I expect is prices to come down a notch. Like 16C/32T costing near to $500 if not reaching sub $500 mark. 12C/13T be sub $400 offering and 8C/16T be price below $300 mark. Now asking for 24C/48T or 32C/64T on mainstream lineup is meaningless. I don't think AMD will going up the core count at-least for this generation.

    Perhaps the lower TDP are to be used by OEM, while the 65W ones are to be sell to the general public?

    I can't help but be curious as to how well these overclock, and also how they perform at the same clock vs chiplet Ryzen.

    If GPU performance is remotely important, I can't help but think you'd be vastly better served spending a little more on a cheap dGPU and a cheap CPU combo. Unless you're set on a form factor that's really tiny and doesn't even support one turned 90 degrees... at which point you might want to consider a GE model.

    That being said, the GPU in 4000 is faster clock for clock, so the final difference in performance probably isn't quite as large as you think. I'd bet the hexacore models with 7CU clocked at 1900 would match it - price obviously will be a deciding factor.

    Rumored that clockspeed for GPU is up to 2.1Ghz.

    As for the reason for going for a fast iGPU is because the ITX (InWin Chopin) case I use does not allow for a dedicated graphic card. I actually have a spare GTX 950M, which unfortunately can't be used in this case. I would like to keep it that way since the rig is going to be for home entertainment, and perhaps some light games.

    Personally, I feel the 8 core Renoir on a desktop is kind of an odd product to me. My impression is that people buy an APU if they don't need a powerful rig/ or on a budget (without having to buy a graphic card). Now if the price of the 8 core part is close to that of the existing 3700X, I don't think it will fit any of the 2 deciding factors mentioned. If I am on a budget, I end up with a 4 core chip with a Vega 6 doesn't sound that attractive. Granted that the CPU is more powerful, and the GPU is pretty much going to be on par or slower since its lost 20% and 80% of CUs, as compared to the Vega 8 and Vega 11 respectively, on the older Ryzen APU.

    It does still feel odd, but remember, budget CPUs now have 4 cores and performance on par with i7s from just a few years ago. 6-8 cores is rapidly becoming mainstream, and now if you want an IGP and 6+ cores you have options from AMD. Anyway, if you can swing it, I think you might want to get the hexacore and pair it with a B550 for future upgrades (unless you already have a board).

    Anyway yeah, that's a fairly snug case: CPU die surface to side panel height: 43mm Maximum

    Yeah not a lot of space there. Maybe wait and see how the GE models perform. :P
