AMD AM5 Zen4 Performance Sneak Peek (Cinebench R23 + Memory Scaling)

MageTank

You clicked this thread to see the performance results of the new AM5 processors, so lets skip the boring word fluff:

•  Motherboard: ASrock X670E Steel Legend

•  Cooler: Cooler Master ML240L V2 AIO (pump 100%, fans auto)

•  Chassis: Cooler Master MasterFrame 700 Open Bench

•  Memory: G Skill Ripjaws F5-5600J3636C16GX2-RS5W (2x16GB 5600 C36) (EXPO loaded)

•  Ambient Room Temp: 74F

As for memory scaling:

• Motherboard: ASRock X670E Steel Legend
• Cooler: Cooler Master ML240L V2 AIO (pump 100%, fans auto)
• Chassis: Cooler Master MasterFrame 700 Open Bench
• Memory: Varies (component under test)
• CPU: Ryzen 9 7900X
• Ambient Room Temp: 74F

Note: Red is average, green is minimum. Benchmark was configured on 1080p Extreme preset, 3 passes enabled and averaged. Results sorted by minimum framerates.

Memory on this platform is configured in a 3:2 ratio (MEMCLK/FCLK) instead of 1:1 from previous Ryzen generations. This means if you have a memory frequency of 6000Mhz, you have a fabric frequency of 2000Mhz. On previous Zen processors, unstrapped ratios resulted in a hard 10ns latency penalty, haven't done any real latency testing or manual memory overclocking yet to confirm this. Will be spending a lot of time testing this architecture to figure this out. So far, scaling seems to be pretty poor if we are just comparing EXPO from 4800 to 6000. If anyone knows of better games to test memory frequency on, let me know and I'll run through more tests.

Thanks for sharing these benchmarks!
