GB10 Boxes Compared: Similar gpt-oss-120b Speed, Prices $4,759 to $7,967

Six NVIDIA GB10 boxes sold in the US land close together on gpt-oss-120b in StorageReview's vLLM serving tests: four boxes from one March series sit within 9.8% at batch 64, and two later runs fall in the same range. Their listed US prices, for different configurations and dates, run from $4,759 to $7,967. Speed does not separate them. Price, stock, storage and cooling do.

The boxes are NVIDIA's DGX Spark, the ASUS Ascent GX10, the Acer Veriton GN100, the Gigabyte AI TOP ATOM, the Dell Pro Precision with GB10 and the HP ZGX Nano. This piece builds on our reviews of the Dell Pro Precision with GB10, the Gigabyte AI TOP ATOM, the HP ZGX Nano and the DGX Spark. Since Oct. 30, Dell.com has listed its 128 GB model at three different prices, ASUS's US store showed the GX10 out of stock on Nov. 2, and CDW lists the Gigabyte ATOM at $7,312, below its $7,999.99 list price.

Why GB10 Boxes Perform Alike

Every box here is built on the same GB10 Grace Blackwell Superchip with 128 GB of LPDDR5X memory on a 256-bit bus. NVIDIA specifies 273 GB/s of bandwidth, and the CPU and GPU share that one pool. When a model writes text, each new token requires reading the model's active weights from that memory, so bandwidth sets the ceiling on speed. All six makers share that ceiling. What they change is the case, the fan curve, the SSD and the price tag. NVIDIA says one 128 GB unit runs models of up to 200 billion parameters. A 120B model such as gpt-oss-120b therefore fits on any of them.

gpt-oss-120b Speed: One Lab, One Test, Three Dates

StorageReview ran the same vLLM online serving benchmark on each box. It used gpt-oss-120b with equal input and output lengths (Equal ISL/OSL) and swept the batch from 1 to 64 concurrent requests. The batch-64 figure is total throughput across all requests, not the speed one user sees.

Four of the boxes were tested in one series, published Mar. 3, 2026. At batch 64, the Gigabyte ATOM reached 649.62 tok/s, the Dell 670.83, the ASUS 680 and the Acer 713.18. At batch 1, a single user's case, they ran 60.71, 68.57, 70 and 69.65 tok/s. The Acer finished 9.8% ahead of the Gigabyte. In the text of those reviews, StorageReview named the Founders Edition Spark as a reference but did not state its numbers.

The HP ZGX Nano came later, in a review published Apr. 24. It ran the same three workloads and climbed from 69.6 tok/s at batch 1 to 722.9 tok/s at batch 64. That is the top figure in the set, 11.3% above the Gigabyte. Because it comes from a separate run a month and a half later, part of that lead may reflect software rather than hardware. StorageReview did not say.

The DGX Spark's figure is from a third date. In its July 6 review of AMD's Ryzen AI Halo, StorageReview measured the Spark at 701 tok/s at batch 64, with 256 input and 256 output tokens stated, against 222 tok/s for the Halo. We covered that gap in our Halo review. The model and tool match the March series, but the software stack was four months newer. Treat it as the same ballpark, not a ranked result.

On the March figures alone, the spread is under 10%. Adding HP's April run and the Spark's July run widens it to 11.3%, and nothing in the data shows any box pulling away. A single user should also expect less than these totals. Notebookcheck, using its own test rather than StorageReview's, saw gpt-oss 120B on the HP drop below 5 tok/s as the context filled.

GB10 Price Spread: $3,208 for the Same Chip

Dell.com listed the Dell Pro Precision with GB10, with 128 GB and its default 2 TB Gen4 QLC drive, at $7,967 at 16:40 UTC on Nov. 2. It read $8,103 earlier that day and $6,593 on Oct. 30. That makes it the most expensive box here and the one whose price has moved most.

CDW advertised the Gigabyte AI TOP ATOM with 128 GB and 4 TB at $7,312 on Nov. 2, against a $7,999.99 list price. NVIDIA's enterprise marketplace showed the DGX Spark with 128 GB and 4 TB at $6,950 in a copy cached on Oct. 31. Its stock is unverified, and the same listing read out of stock on Oct. 21. The Spark launched at $3,999 in October 2025.

The ASUS eShop in the US lists the Ascent GX10 with 128 GB and 1 TB at $5,999. On Oct. 30 and again on Nov. 2, it showed the unit as out of stock, with a notify-me button only.

HP's own product page shows no price for the ZGX Nano. Notebookcheck, in a review updated Oct. 5, reported $7,399 at the HP Store for the 4 TB model and $4,759 on Amazon. That Amazon price is the low end of the range, and it is a month old. Acer announced the Veriton GN100 from $3,999 in North America in September 2025. We found no current US listing to confirm that it still applies.

Since Oct. 23, NVIDIA's partners have also sold a 64 GB GB10 configuration from $4,999, as Voltgrid reported. NVIDIA rates it for models of up to 100 billion parameters, so gpt-oss-120b is out of reach on one unit. No independent lab has published tests of it yet.

Cooling, Storage and Power Compared

The boxes differ more on thermals than on speed. In StorageReview's one-hour, three-stage load ramp, the Acer peaked at 74.7°C on the CPU and 69°C on the GPU, the coolest of the group. The HP peaked at 77.3°C and 69°C in its April run. The ASUS reached 87.3°C and 82°C, and the Dell about 87.7°C and 80°C. The Gigabyte ran hottest at 90°C and 81°C, with GPU power peaking at 75.54 W, the top of the group. StorageReview found that all of them settled once the burst phase passed.

Storage is where the configurations split. StorageReview put the ASUS's 1 TB Gen4 SSD near the bottom of its storage tests. The Dell ships a QLC drive on its 2 TB model, offers no Gen5 option, and logged the warmest NVMe drive in the group. The Gigabyte supports up to a 4 TB Gen5 SSD and posted some of the best GPU Direct Storage results. Dell is also the only one with a 280 W adapter. NVIDIA, ASUS, Gigabyte and HP ship 240 W supplies.

Which GB10 Box to Buy

For the lowest outlay on a 128 GB box with a full independent review, buy the HP ZGX Nano if the $4,759 Amazon price Notebookcheck reported is still available. It ran cool, and it posted the top batch-64 figure in StorageReview's tests. At HP's own $7,399, the case for it is weaker.

For a quiet desk or a warm office, the Acer Veriton GN100 ran coolest and matched the field on speed. Confirm a current price first, because Acer's $3,999 is from September 2025.

For a team that wants NVIDIA's own software image and support, the DGX Spark at $6,950 sits mid-range for 4 TB. Its stock was unconfirmed when we checked.

For large local datasets, the Gigabyte AI TOP ATOM's 4 TB Gen5 option and its GPU Direct Storage results justify its $7,312 CDW price. It runs hottest under bursts, so give it room to breathe.

The ASUS Ascent GX10 is the value pick at $5,999 once it is back in stock. Its 1 TB drive is the trade-off.

The Dell Pro Precision with GB10 at $7,967 measured no faster than the $5,999 ASUS in the same StorageReview series. Buy it for Dell procurement and support, and wait for its price to settle.

Skip the 64 GB GB10 systems at $4,999 if gpt-oss-120b is the target, and wait for the first independent tests. If vLLM serving is the job, AMD's $3,999 Ryzen AI Halo is not a substitute: it reached 222 tok/s against the Spark's 701 on the same test.
