GPU Codename	NV10
Architecture	Celsius / NV10 fixed-function DirectX 7 GPU with hardware transform and lighting
Launch Date	1999-08-31
Launch MSRP	About $249 to $299 for early 32 MB boards, depending on partner and memory type
Market Segment Notes	High-end desktop gaming and enthusiast 3D graphics
Core Specs
GPU Die	NV10
Process Node	TSMC 220 nm
Transistor Count	About 17 million in GPU database sources; some launch-era coverage quoted nearly 23 million for the broader GeForce 256 chip description
Die Size	About 139 mm2
CUDA Cores	Not applicable
SM Count	Not applicable
Base Clock	120 MHz
Boost Clock	Not applicable
Memory
Memory Size	32 MB typical; some later board-partner variants used 64 MB
Memory Type	SDR SDRAM or SGRAM on early cards; DDR SDRAM or DDR SGRAM on later DDR cards
Memory Bus Width	128-bit
Memory Clock	166 MHz SDR on SDR boards; 150 MHz DDR clock, 300 MT/s effective, on DDR boards
Memory Bandwidth	2.656 GB/s on SDR boards; 4.8 GB/s on DDR boards
Board and Display
TDP / TBP	About 12 to 13 W class, depending on SDR or DDR board design
Power Connectors	None
Interface	AGP 2x / AGP 4x depending on board and platform
Display Outputs	15-pin VGA on typical boards. Some board-partner designs exposed or provisioned DVI, S-Video or TV-out.

Driver Branch Notes	Period Windows 9x, Windows 2000 and early Windows XP Detonator or ForceWare-era drivers are the practical target. NVIDIA driver support for this generation ended long ago.
Windows Support Notes	Best matched with Windows 98 SE for period gaming. Windows 2000 and early 32-bit Windows XP can work with legacy drivers, but later Windows versions are not a practical target for 3D use.
Linux Support Notes	Only legacy NVIDIA driver stacks or older open-source display support are relevant. There is no practical modern accelerated Linux target.

Why It Mattered

GeForce 256 is a priority historical entry because NVIDIA used it to introduce the GeForce brand and popularize the term GPU around an integrated transform, lighting, setup, and rendering processor. The page should distinguish NVIDIA's launch framing from later, broader uses of the word GPU.

Launch Context

The launch context should cover the 1999 transition from late RIVA-era accelerators to the first GeForce-branded product, with NVIDIA's own anniversary material and archived product pages used as primary references where possible.

Architecture Context

Architecture notes should focus on the hardware transform and lighting claim, integrated rendering pipeline, and the limits of that fixed-function era. Avoid projecting later programmable shader or CUDA-era ideas onto this entry.

Collector Relevance

Collector notes should separate SDR and DDR retail cards, memory type, driver media, and board partner packaging only after archive or manual sources are attached.

Used-Market Caution

Confirm SDR versus DDR before buying, because the difference is meaningful. Also check AGP keying, cooler condition, output configuration, memory size, board-partner model, and whether the card has been modified.

Known Issues

The SDR model is often memory-bandwidth limited. DDR boards are more desirable but can be harder to find. Some launch-era claims and database sources disagree on transistor count, so the entry records both the common database figure and the higher launch-era quote.

Known Failure Points

Small cooler failure, AGP compatibility, and SDR-versus-DDR confusion are common. Driver support is legacy-only, and later Windows versions are not the right target for a clean period experience.

Driver and Platform Notes

Period Windows 9x, Windows 2000 and early Windows XP Detonator or ForceWare-era drivers are the practical target. NVIDIA driver support for this generation ended long ago.

Only legacy NVIDIA driver stacks or older open-source display support are relevant. There is no practical modern accelerated Linux target.

Best matched with Windows 98 SE for period gaming. Windows 2000 and early 32-bit Windows XP can work with legacy drivers, but later Windows versions are not a practical target for 3D use.
