AMD is announcing several new updates for its desktop products, including the official introduction of 105W mode for mid-range Ryzen 9000 series processors, as well as support for faster DDR5 modules on supported motherboards.
New 105W Mode For Ryzen 7 9700X & Ryzen 5 9600X
The initial reviews of the Ryzen 7 9700X and Ryzen 5 9600X has proved that the decreased power limit of these chips has hindered its multi-core capabilities, and it’s evident that increasing the power limit is the best way to gain more performance. Various motherboard makers has already released their own 105W mode in earlier BIOSes, but AMD today has made that official with all BIOSes featuring AGESA PI 1.2.0.2 and above to gain this feature.
AMD says the 105W power limit for these chips has already been validated since their release, and they will continue to honor the warranty as usual. These chips will still run at 65W TDP by default, so users will have to do a quick visit to their respective systems’ BIOS menu to enable the higher power limits.
Improved Core-to-Core Latency
Besides the mid-range Ryzen 9000 chips, the dual-CCD Ryzen 9 models also gets improved core-to-core latency that was lost from its predecessors. “This was mainly due to some corner cases where it
takes two transactions to both read, and write, when information is shared across cores
on different parts of a Ryzen 9 9000 processor,” the chipmaker statement reads.
The same AGESA update will “cut the number of transactions in half” – according to AMD, the update should best benefit “heavily threaded games that don’t trigger core parking.” These include games like Starfield, Borderlands 3, as well as the 3DMark Time Spy benchmark.
DDR5-8000 EXPO Support
Additionally, AMD also announced that its motherboards will now support DDR5-8000 EXPO profile (though it didn’t specify if this applies to both 600 and 800 series motherboards). When paired with these modules, the latency should reduce 1-2ns (DDR5-6000 usually has ~69ns latency) that can benefit in games reliant on memory latency. Of course, these modules won’t come cheap – though there are even faster modules on the horizon that may benefit Intel processors in the near future.
Pokdepinion: Good updates – looking forward to see how DDR5-8000 fares on Ryzen platforms.
