GeForce RTX 5090 is a card, not a computer: every price shown for it is the cheapest listing we found plus $1,000 for the minimum host machine.
memory = 1600B × 0.604 B/param (4.83 bits) + 0.009 GB/1K × 8K K/V + 1.2 GB runtime
speed = bandwidth × 0.5 ÷ (49B active × 0.604 B/param) = 29.6 GB read per token
usable = memory − operating system reserve (8% on a Mac, 6% on a DGX Spark, 4% on a card)
Bandwidth is the vendor’s published figure. Every speed is an estimate and says so. Methodology.
