According to wccftech.com, the first AMD Ryzen 4000 'Renoir' desktop CPUs are obviously already in circulation and one of these copies has now been discovered by the hardware supplier _Rogame. The Ryzen 4000 'Renoir' CPUs (essentially an APU) are based on the 7 nm architecture and are equipped with the new Zen 2 CPU and improved Vega cores to achieve significantly better performance than the existing 12nm Ryzen 3000 'Picasso' chips.
However, the AMD Ryzen 4000 'Renoir' product line should not be confused with the Zen 3-based Ryzen 4000 CPUs that we will see later this year. The "real" Ryzen 4000 CPUs based on the Zen 3 architecture are known as Vermeer, while the Zen 2-based Ryzen 4000 series of APUs is known as Renoir. The Ryzen 4000 family will soon be using the 3rd-form chips. generation introduced the mobile division, but it almost looks as if the Ryzen 4000 "Renoir" desktop APUs are already on the way for entry-level and budget PCs.
An AMD Ryzen 4000 'Renoir' desktop CPU has now been discovered by _Rogame running on an AORUS (gigabyte) B550 PRO AC motherboard. The motherboards based on the AMD B550 and A520 chipset are expected to be launched in the coming months. The CPU, which is an early sample, has a base clock of 3.5 GHz and has a GPU clock speed of 1750 MHz. This is the same clock rate as the Ryzen 7 4800H and Ryzen 9 4900H, which could indicate that the chip uses their 8-CU design with 512 cores. The improved Vega graphics chip on the APU will certainly also provide a good performance improvement over the 12 nm components of the Ryzen 3000G series.
The core and thread configuration for this chip is unfortunately not mentioned, but the total score for this APU in the 3DMark11 is given as 5659 points. This is followed by a comparison with the other products of the AMD Ryzen 4000 U-Series in the same benchmark.
3DMark 11 Total Performance Benchmark:
AMD Ryzen 4000G Series Desktop CPU – 5659 points
AMD Ryzen 7 4800U 'Renoir' Mobile CPU – 6309 points
AMD Ryzen 7 4700U 'Renoir' mobile CPU – 5713 points
The score is definitely lower than that of the mobile 15W parts, while the Ryzen 4000G series CPUs are likely to work with 45-65W TDPs. An important circumstance mentioned in the leak is that the chip was only tested with DDR4-2133 MHz, which probably explains the much lower result. AMD's CPUs with Vega graphics scale very well with a higher memory clock, and these 2133 MHz aren't what you might call fast memory at all.
So it's a standard-only RAM that meets the specifications of JEDEC, so you can expect the final performance of the Ryzen 4000G series to be much higher. In addition, it is not known which specific core/thread configuration this chip offered, so this is also a factor to consider when classifying the results. Regardless, you can expect the Ryzen 4000 series 'Renoir' desktop CPUs to be launched in the second half of this year for budget platforms such as the B550 and A520 motherboards. They will certainly aim for prices similar to their predecessors, but that is also to be expected.
