Blackwell rental prices so far: B200, B300 and GB200

What Blackwell rents for, as listed

Blackwell cards are listed here under three names. The B200 SXM 192GB has a lowest listed on-demand rate of $3.74 across 22 sellers. The B300 SXM 288GB has a lowest of $4.00 across 13. The GB200, listed as GB200-NVL72, has a lowest of $9.99 across 2. Each is a seller's cheapest on-demand list rate per GPU-hour, from its own page.

Each has a card page: the B200, the B300 and the GB200. The B200 alone is read in more detail in the B200 post.

Why so far is the right frame

Seller counts for these cards are the first thing to read. When a count is small, the market for that card on this site is thin: the lowest and highest rates are one or a handful of pages, and one new listing can move both. That is true of whichever Blackwell row has the smallest count on the day you read this.

A thin row is not a wrong row. It is a few public quotes, each with its source and date, and it says nothing about how much capacity changes hands on contract. Read it as what sellers publish now, not as where the price will settle.

For a seller, a thin row is also an opening that closes. The first public rates on a new card are the ones buyers see while the row is short, and they frame what later sellers are compared against. Publishing an on-demand rate early, on a page that can be read, puts that seller in the frame.

Where a row has a single seller, there is no spread and no second name to report, and the card page says so rather than inventing one.

Memory across the three

The B200 carries 192 GB and the B300 carries 288 GB. In 16-bit, weights take about 2 bytes per parameter, so 288 GB holds the weights of a model of roughly 140 billion parameters, against roughly 96 billion on 192 GB, before any key-value cache. The cache grows with context length and batch size, so the usable limit is lower.

That memory step is the case a B300 seller makes for its rate. A buyer whose model fits on one B300 but not on one B200 is comparing one card against two, and the rate per card is only half of that sum.

The GB200 is listed under the name sellers use for it, GB200-NVL72. We hold its rate per GPU-hour like any other card, and this post states nothing about its configuration beyond that name.

For a seller that leaves one thing to do on the page: say how the GB200 is sold. If it is rented only as a whole system, or only by the GPU, the buyer needs to know before the hourly rate means anything to them, and a rate quoted without that context is hard to compare with the B200 and B300 rows.

How the Blackwell rows are read

One rate per seller per card goes in, the cheapest on-demand list rate on the seller's own page, per GPU per hour. A page quoting only a node or rack price with no plain card count is not divided. Reserved terms and quotes on request stay out, and a rate whose last good read is more than 21 days old is hidden.

For new cards that last rule bites. A seller that publishes a rate, then moves it behind a contact form, drops out of the row once its last good read is more than 21 days old. The method page describes the reads.

The highest listed rates sit beside the lows on each card page: $11.12 for the B200, $13.80 for the B300 and $10.50 for the GB200. Where a row has one seller the high and the low are the same quote, so a seller reading them should check the count before reading anything into the distance between them.

What a Blackwell seller should check

Name the card and the memory together, and keep the B200, B300 and GB200 apart on the page. In a thin row a rate in the wrong place is not one wrong figure among many; it may be the whole row for that card.

State the unit as per GPU per hour, and the commitment beside it. If your Blackwell capacity is sold mainly on term, say so and publish the on-demand rate if there is one, because the on-demand rate is the only one that enters the table.

A claimed listing lets a seller correct a figure held for it. On a new card, where the first rates set the range, check the card page in the week a rate is published.

What the Blackwell figures cannot tell

No benchmark data is held, so nothing here compares Blackwell with Hopper on work done per hour, and nothing compares the three Blackwell parts with each other beyond rate and memory.

The figures also hold no availability and no contract prices. For cards this new, both may matter more to a buyer than the list rate, and both are outside what this site reads.

Nor can the figures say how Blackwell rates relate to Hopper rates over time. The lowest listed H100 SXM rate is $1.68 today, and a buyer will set it beside these rows, but a single day's figures say nothing about direction. The card pages show the current read, not a trend.
