Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) vs Lenovo ThinkStation PX (4x RTX PRO 6000, 384 GB)
Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) · Lenovo ThinkStation PX (4x RTX PRO 6000, 384 GB)
Verdict
- throughputThe Lenovo ThinkStation PX (4x RTX PRO 6000, 384 GB) delivers approximately 14% higher aggregate decode throughput across the 8 models both machines can run (geometric mean of the per-model ratios).
- capacityBoth machines run all 8 compared models, so this is a pure speed and cost decision rather than a capability one.
- costAt 8 hours a day, the Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) has approximately 37% lower total monthly cost ($467 against $746), for a C corporation in United States (federal).
- powerThe Lenovo ThinkStation PX (4x RTX PRO 6000, 384 GB) draws 1580 W under load against 920 W for the Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) — a 1.7× difference that shows up in the electricity line and in how loud and hot the room gets.
- evidenceEvery throughput figure in this comparison is estimated. Treat the ranking as indicative and the margins as unreliable.
- recommendationThere is no single answer: the Lenovo ThinkStation PX (4x RTX PRO 6000, 384 GB) is faster, the Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) is cheaper to own, and the Dell Precision 7960 Rack (2x RTX PRO 6000, 192 GB) gives more throughput per unit of purchase currency. Pick on whichever constraint actually binds you — interactive latency, monthly budget, or capacity headroom for larger models later.
Every statement above is generated from the calculations on this page by fixed rules — no prose is written for individual comparisons. If the numbers change, the verdict changes with them.

Differences under 10% are reported as a tie: they are smaller than the spread between published benchmarks of the same configuration, so calling a winner would be false precision. Rows where a model fits on only one machine are decided by capacity, not speed.
