A B200 costs 10% less than a B300 per unit of peak compute. Real work reaches a fraction of peak, and the fraction differs by job.

2Method

The Racks B300 index follows what an NVIDIA B300 rents for by the hour. It counts two published rates: Compute Desk’s US 1-year desk rate and Silicon Data’s rental index for neo-clouds. Each is compared with where it stood when the period opened.

The index moves by the geometric mean of the two changes: multiply them and take the square root. Each change counts in full, and the index needs two live sources, or it holds its level.

Index = 100 \times \prod_{i = 1}^{2} {(\frac{p_{i}}{p_{i, 0}})}^{w_{i}}

(1)

Equation 1. The index. Here p_i is a source’s counted price now, p_i,0 its counted price when the period opened, and w_i its weight. The weights add up to 1, and each is one half while both count. The Racks B300 index follows the geometric mean of two published B300 rental rates: Compute Desk and Silicon Data.

**Table 3.** The 2 changes this week and the index they make.
Source	Ratio to the open	Change
Compute Desk	0.9933	−0.67%
Silicon Data	0.9987	−0.13%
$100 \times {(0.9933 \times 0.9987)}^{\frac{1}{2}}$
Index		99.60

The price in $/hour is the geometric mean of the two prices when the period opened, moved by the index: while both count, the geometric mean of the two prices now.

The rules are in the docs.

3Questions

What does a B300 cost to rent per hour?

The B300 rental price index stands at $7.56 per GPU-hour as of Nov 10, 2026, 10:45 UTC. It is an index of two published rental rates, so what one provider charges can differ.

What is the B300 rental price index?

Racks’ index of what an NVIDIA B300 rents for by the hour. It counts two published rates: Compute Desk’s US 1-year desk rate and Silicon Data’s rental index for neo-clouds. Every period starts at 100, and the index shows how far prices have moved since, in percent. The price in $/hour is the geometric mean of the two prices when the period opened, moved by the index: while both count, the geometric mean of the two prices now.

Can I check the number?

Yes. The Method section of this page shows how the index is built from the two published rates, and the docs give the method in full.

Before Oct 12 the history is back-calculated: the index’s rule applied afterwards to stored prices, not the levels posted at the time. Before October 2026 it follows Compute Desk alone. The figures marked with this note include it.
The Racks B300 Index chains each week’s index into one long series, from 100 at the open of the week of Nov 3, 2025. The docs give the rule.
