In a revelation that could reshape how gamers build their PCs, AMD has shared new data indicating its upcoming Ryzen 7 9850X3D processor is remarkably insensitive to memory speed. According to a presentation slide obtained for the chip’s launch, the average gaming performance difference between using DDR5-4800 and DDR5-6000 memory is less than 1%.
This finding is particularly significant given the current state of the memory market, where prices for fast DDR5 kits have skyrocketed. It suggests builders could opt for more affordable, slower memory without sacrificing meaningful gaming performance when using AMD’s cache-rich X3D processors.
The Data: Minimal Gains Across a Wide Game Suite
AMD’s testing compared a 2x16GB configuration of DDR5-4800 against DDR5-6000. Across a suite of over 30 games, the average frame-per-second (FPS) difference was under 1%. Specific title results shown in the chart were equally minor:
- Cyberpunk 2077: +0.2%
- Far Cry 6: +0.5%
- Red Dead Redemption 2: +0.6%
- Warhammer 40,000: Space Marine 2: +1.6%
This minimal delta is a stark contrast to standard CPUs, which often show gains of 5-15% from similar memory speed increases. The reason lies in the 96MB of L3 cache on the 9850X3D, including 64MB of stacked 3D V-Cache. This massive, ultra-fast cache pool serves data to the CPU cores so efficiently that it drastically reduces the system’s dependency on fetching information from the slower system RAM.
A Cost-Saving Insight During a Memory Crisis
AMD directly tied this performance insight to the current market reality. The company cited PCPartPicker data from January 9 showing a $70 price difference between a DDR5-4800 kit (~$400) and a DDR5-6000 kit (~$470). With memory prices continuing to climb, that savings gap may widen, making the slower kit an increasingly intelligent value choice for a gaming rig built around an X3D CPU.
The company also claims a 3% to 7% generational performance uplift for the 9850X3D over the previous 9800X3D, attributable to its higher 5.6 GHz boost clock. This positions the new chip as a straightforward performance upgrade for AM5 platform owners.

Practical Advice for PC Builders
For anyone planning a system with the Ryzen 7 9850X3D, launching next week, this data provides clear guidance:
- Prioritize Capacity Over Speed: Focus on getting enough RAM (e.g., 32GB) rather than paying a premium for extreme speeds.
- Re-allocate Your Budget: The money saved on memory can be directed toward a better GPU, more storage, or a higher-quality power supply—components that will have a more direct impact on performance.
- Ensure Compatibility: Even a DDR5-4800 kit must be on your motherboard’s qualified vendor list (QVL) for stability.
