| Length | 163 mm | 267 mm |
| Width | 1-slot | 2-slot |
| Supplementary power connectors | None | 1x 8-pin |
VRAM capacity and type
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
| Memory type | GDDR6 | GDDR6 |
| Maximum RAM amount | 4 GB | 32 GB |
| Memory bus width | 64 Bit | 256 Bit |
| Memory clock speed | 1500 MHz | 2375 MHz |
| Memory bandwidth | 96 GB/s | 608.0 GB/s |
| Resizable BAR | + | + |
Connectivity and outputs
This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.
| Display Connectors | 4x mini-DisplayPort 1.4a | 1x HDMI 2.1a, 3x DisplayPort 2.1 |
| HDMI | - | + |
API and SDK support

Synthetic benchmarks
Non-gaming benchmark results comparison. The combined score is measured on a 0-100 point scale.
Passmark
This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
Pros & cons summary
| Recency | 16 April 2024 | 26 March 2026 |
