Overview
SummaryThe AMD Ryzen 9 6900HX is a laptop processor with 8 cores and 16 threads, built on the Zen 3+ architecture (6 nm process). It launched in Jan 2022. Clocks run from 3.3 GHz base to 4.9 GHz boost. A 16-MB L3 cache backs the cores (2.6 MB per core). It supports DDR5, LPDDR5 memory. The chip drops into the FP7 socket and exposes PCIe 4.0 (16 lanes). Rated TDP is 45 W. Feex currently counts 1 machine in its hardware fleet with exactly this processor.
Performance
12 metricsThe AMD Ryzen 9 6900HX scores 3,362 in single-core performance and 24,026 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,988 for overall performance, 20,324 for productivity performance, 19,266 for creator performance, 24,627 for engineering performance and 16,093 for gaming performance. Its multi-core throughput works out to 3,003 per core, 1,502 per thread and 534 per watt. Its computed efficiency index is 1,340. Its performance index is 111, so its overall performance is 11% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks

1 machineAcross 1 Feex machine with the AMD Ryzen 9 6900HX, the busiest recorded minute reached 10.0 FCU/s; in 95 percent of recorded hours the busiest minute stayed under 10.0 FCU/s (19.0% of its 52.8 FCU/s capacity), and a typical hour averaged 1.94 FCU/s.
Minute resolution
Not recorded: 0 valid machine-minutes so far, below the 60 needed to publish minute percentiles.
Hour resolution
13 valid machine-hours from 1 Feex machine, September 23, 2026 to September 27, 2026. Hourly peak is the busiest minute of each hour; 0 hours were excluded from peak statistics as over 102 percent, and 10 hours with fewer than 30 reported minutes were left out.
Average compute by hour of day
Withheld: an hour-of-day curve is shown once at least 3 Feex machines with this processor contribute, so no individual's daily schedule can be read from it.
Top programs by measured compute
Withheld: program names are shown once at least 3 Feex machines with this processor ran them, so no individual's app usage can be read from this page.
Tier 3 estimate: FCU/s = whole-machine CPU utilization x logical threads x base clock x reference IPC 1.0 (1 FCU = one billion instructions). Boost clocks and real IPC are not measured, so this describes how hard these machines were driven, not a benchmark. Data through September 27, 2026. Because fewer than 3 machines contribute, these figures cover whole days (UTC) and are updated once per day.
