It seems that AMD may be preparing a new and more extreme version of one of its Ryzen 4000 mobile APUs. Hardware detective @TUM_APISAK 3DMark benchmark results unearthed today for a “Ryzen 7 Extreme Edition” CPU allegedly Renoir,
It is strange to see the words “Extreme Edition” in the name of an AMD processor. That appointment is more of an Intel practice that dates back to the Bloomfield days.
In terms of design, the dark Ryzen 7 APU registers with eight CPU cores and 16 threads. It appears to work with a 1,800 MHz base clock and 4,291 MHz boost clock. The low base clock is a clue that the APU is likely based on one of AMD’s Ryzen 4000 U-series parts that work with a TDP of 15W.
There are two Ryzen 7 SKUs in the Renoir mobile line, but only the Ryzen 7 4800U has an eight-core, 16-wire configuration. Therefore, we suspect that the leaked APU is based on the Ryzen 7 4800U. The Vanzen Ryzen 7 4800U has a 1,800 MHz base clock and a 4,200 MHz boost clock. The Extreme Edition appears to come with a higher 100 MHz boost clock.
The Twitter user also found a Ryzen 9 4900U a few hours before tweeting about Ryzen 7 Extreme Edition. Oddly enough, the Ryzen 9 4900U apparently has identical specs to the Ryzen 7 Extreme Edition.
There’s a good chance that one, or perhaps both, of the mysterious APUs were designed exclusively for Microsoft. AMD has produced bespoke APUs for Microsoft Surface devices in the past. The custom APUs were almost identical to the original SKUs, but the Microsoft variant had an additional Vega Computing Unit (CU). Ryzen 3000 U-series chips (codename Picasso) originally peaked at 10 CU and Microsoft’s custom-made APUs increased the count to 11.
Howerver, AMD labeled the Microsoft APUs as “Surface Edition”, not Extreme. By removing the Surface nickname from APUs, AMD could offer them to other customers, too.
