The 64 GB version has been officially announced
On October 2, 2026, NVIDIA announced a DGX Spark configuration with 64 GB of unified memory. It is scheduled to be available through Acer, ASUS, Dell, Gigabyte, HP and MSI starting Friday, October 23, 2026, at a starting price of $4,999. As of October 3, 2026, that date is still in the future. The announcement does not confirm stock at every seller or availability in every country.
The 64 GB version retains the GB10 Grace Blackwell, DGX OS and NVIDIA software found in the 128 GB version. Those announced shared features do not replace independent performance testing. Memory capacity alone cannot establish which models can run under particular conditions or how quickly the system will perform.
The $4,999 starting price and October 23, 2026 date are now confirmed by NVIDIA’s announcement. The price is a US-dollar starting price, not necessarily the final price in every region; taxes and configurations may differ. Availability should also be checked with the named sellers for the relevant country and date.
Price and availability: announced, with regional details still to check
NVIDIA has announced a $4,999 starting price and availability through Acer, ASUS, Dell, Gigabyte, HP and MSI starting October 23, 2026. Since October 3, 2026, precedes that date, the announcement does not mean the system is already on sale or in stock at every seller.
The announced date and sellers are confirmed. What remains unknown is the precise sales situation in each country, including whether units will actually be available there from launch day. Prospective buyers should check local pricing and stock with NVIDIA or the relevant sellers.
The $4,999 figure is the announced starting price. It should not automatically be treated as the final price in every region or compared with the 128 GB configuration without qualification. A meaningful comparison needs prices for the same market, applicable taxes and comparable configurations; a complete economic comparison is not yet available.
The announcement confirms the configuration, starting price, launch date and named sellers. It does not confirm stock in every country, local final prices or independent system performance. Those points need to be assessed separately.

What actually changes when moving from 128 GB to 64 GB
The announced 64 GB configuration has half the unified memory capacity of the 128 GB version. That is a capacity comparison, not a measure of performance: it does not, by itself, establish which models can run under particular conditions or how long a task will take.
Total memory is not necessarily the same as memory available to a model. Some capacity may be needed by the operating system, runtime environment, input data and other processes. Requirements also depend on how model weights are stored, the precision and context length used, and the optimizations applied. The announcement does not provide independent tests quantifying these factors for specific workloads.
It is also important to distinguish among three types of workload. Inference generates responses with a prepared model; fine-tuning requires additional resources that depend on the method; and developing agents may involve several components working together. A system’s ability to run a workload does not establish how quickly it can do so or what context length it can support. Independent test results for the 64 GB version are not available.
NVIDIA confirms that the 64 GB version retains the GB10 Grace Blackwell, DGX OS and NVIDIA software found in the 128 GB version. These shared features do not establish performance for particular models or workloads. That requires information about test conditions and independent, reproducible results.
The comparison with the previous model is still incomplete
NVIDIA has announced a $4,999 starting price for the 64 GB version. The available information does not provide a complete price comparison with the 128 GB version. Without comparable prices for the same market and time, including taxes and configuration differences, potential savings and value for money cannot be established.
A technical comparison should account for NVIDIA’s confirmation that both configurations share the GB10 Grace Blackwell, DGX OS and NVIDIA software. The information available is not enough for a complete comparison of all technical features, usable memory or software compatibility. Other similarities should not be assumed from the product name alone.
Before judging value for money, check whether prices refer to the same market and date and account for taxes and configuration differences. The announced $4,999 starting price is not necessarily the final price in every region. Without comparable local prices and independent performance testing, a value judgment about the two versions would be premature.
Checks needed before making a comparison
- 01Review the official details for both configurations and their shared features; consult additional specifications for a complete technical comparison.
- 02Check the announced October 23, 2026 start date and local prices and availability with NVIDIA or the relevant sellers for the country in question.
- 03Compare equivalent configurations and clarify whether prices include taxes.
- 04Test the same workloads using identical models, software versions, context and operating conditions.
- 05Publish results with methodology, power consumption and limitations, not just a single performance figure.
What independent tests would help assess its usefulness
To assess whether the 64 GB configuration suits a particular use case, an independent test should specify the model, format and quantization, context size and memory remaining available. It should also record whether one task or several are running in parallel. Without those details, a claim such as “runs large models” has limited comparative value.
For inference, useful measurements would include time to first response, generation speed and stability across different context lengths. A fine-tuning evaluation should state the method, dataset and how much of the work was performed on the system. For agents, it should describe the tools or components involved and whether the system remains stable over an extended session. Independent test results for the 64 GB version are not available.
An economic comparison should consider actual costs in the relevant market as well as the announced starting price: taxes, any required accessories or storage, and relevant software costs. Independent power-consumption measurements would also help evaluate workloads. A complete cost comparison and independent performance tests are not yet available.
Bottom line: the announcement and starting price are confirmed; performance and local availability remain to be checked
On October 2, 2026, NVIDIA announced a DGX Spark with 64 GB of unified memory. It retains the GB10 Grace Blackwell, DGX OS and NVIDIA software found in the 128 GB version. The announced starting price is $4,999, with availability through Acer, ASUS, Dell, Gigabyte, HP and MSI scheduled for October 23, 2026. As of October 3, that date is still in the future.
The announcement confirms the price and date, but not stock in every country or the local final price. Taxes and regional configurations may affect what buyers pay. There are also no independent tests showing which workloads the 64 GB version can run or how quickly. Memory capacity alone cannot provide a reliable performance prediction.
For a purchase decision, check local prices and actual availability with sellers after the announced launch date. An economic comparison with the 128 GB version requires prices for the same market and comparable configurations. Independent, reproducible tests can then show how the systems perform on specific workloads.
