AMD Ryzen 7 4700G Flagship Renoir APU Overclocked To 4.75 GHz Across All 8 Zen 2 Cores on Standard Cooling
AMD's Ryzen 7 4700G has leaked out once again but this time we are not going to talk about benchmarks of the flagship 8 core Renoir APU but rather its overclock potential which has once again been showcased by ITCooker (via HiFiHedgehog) over at his Facebook page.
AMD Ryzen 7 4700G Flagship Renoir APU Gets Overclocked To 4.75 GHz Across All 8 Zen 2 Cores, Uses Standard Cooling Setup
The AMD Ryzen 7 4700G is looking to be an impressive APU with the performance caliber of the Ryzen 7 3800X in a 65W package. The APU will make use of the 7nm Zen 2 CPU cores & the 7nm Vega GPU cores in a monolithic design compared to the chiplet design we've seen on standard Ryzen 3000 'Matisse' CPUs. The monolithic design does come with slightly better efficiency than chiplet offerings and also offers a marked improvement in latency & bandwidth numbers. We'll definitely wait for final tests to verify this but let's check out today's important feat for the AMD Ryzen 7 4700G.
AMD Ryzen 7 4700G Flagship Renoir APU Specs
The CPU-Z screenshot he provided shows that the Ryzen 7 4700G is based on the 7nm Zen 2 core architecture. It features 8 cores, 16 threads, 4 MB of L2 and 8 MB of L3 cache for a total of 12 MB cache. This is definitely lower than the 32 MB of L3 cache which the 8 core Ryzen 7 3800X features but this is due to the monolithic nature of the chip which relies on a single package rather than the chiplet based design on the Ryzen 3000 'Matisse' series desktop processors.
The CPU features a base clock of 3.60 GHz and a boost clock of 4.45 GHz which matches the earlier specifications leak. The CPU operates with a 65W TDP and is compatible with the AM4 socket. The graphics side features the enhanced 7nm Vega GPU which comes with 8 CUs to form 512 cores. Its clocked at 2100 MHz on the GPU side which makes it one of the fastest clocked integrated graphics chip.

|AMD Ryzen 3 4300G||7nm Zen 2||4/8||3.8 GHz||4.00 GHz||DDR4-3200||Vega 6 / 384 SPs||1700 MHz||65W||$139 US?|
|AMD Ryzen 7 PRO 4750G||7nm Zen 2||8/16||3.6 GHz||4.45 GHz||DDR4-3200||Vega 8 / 512 SPs||2100 MHz||65W||$309 US|
|AMD Ryzen 5 PRO 4650G||7nm Zen 2||6/12||3.7 GHz||4.30 GHz||DDR4-3200||Vega 7 / 448 SPs||1900 MHz||65W||$209 US|
|AMD Ryzen 3 PRO 4350G||7nm Zen 2||4/8||3.8 GHz||4.10 GHz||DDR4-3200||Vega 6 / 384 SPs||1700 MHz||65W||$149 US|
|AMD Ryzen 7 PRO 4750GE||7nm Zen 2||8/16||3.1 GHz||4.35 GHz||DDR4-3200||Vega 8 / 512 SPs||2000 MHz||35W||$309 US|
|AMD Ryzen 5 PRO 4650GE||7nm Zen 2||6/12||3.3 GHz||4.25 GHz||DDR4-3200||Vega 7 / 448 SPs||1900 MHz||35W||$209 US|
|AMD Ryzen 3 PRO 4350GE||7nm Zen 2||4/8||3.5 GHz||4.00 GHz||DDR4-3200||Vega 6 / 384 SPs||1700 MHz||35W||$149 US|
The CPU was once again tested on the ASRock B550 Taichi motherboard with DDR4-3800 MHz CL16 memory. The CPU was overclocked manually with a multiplier of 47.75 and a bus speed of 100 MHz at 1.425V. The result was 4.75 GHz frequency across all 8 cores which is rather impressive when we compare it to AMD's standard Matisse 8 core offerings. The Ryzen 7 3800X or the Ryzen 7 3700X, as far as I can tell, can't break past the 4.3 GHz barrier but here we see the 65W Ryzen 7 4700G going for those higher clocks like a champ.
It's also important to tell that this overclock wasn't done on LN2 cooling but rather a standard air or liquid-cooled setup as is evident by the temperature reported by CPU-z at 41C. Sure the CPU wasn't being tasked to do something and we haven't seen any performance numbers with the said over-clock but we may very well see how the chip performs under such high overclocks. The leaker also reports up to 4.9 GHz clock speeds on a single core and an infinity core clock of 2200 MHz. You can see the listing at the CPU-z validation page here.
Leaked prices for the Ryzen 7 4700G show that it might cost somewhere around the $300 US mark and at that price point, it would make a much better deal than the Ryzen 7 3700X & Ryzen 7 3800X since it will offer the same amount of cores and threads but with higher overclocking capabilities, a built-in iGPU and much better support for higher frequency DDR4 memory. We will be detailing on the launch and segmentation of the AMD Ryzen 4000 Renoir desktop family soon.
