The GeForce GT 640 Graphics Card from ASUS is a computer graphics card with Windows drivers for desktop computers that have PCI Express expansion slots. The card can be used to provide additional processing power to video games, or for other applications that require or benefit from having a dedicated graphics card.
The card features a 1046 MHz GPU, and has 384 CUDA cores (stream processors) that allow applications that support parallel processing to perform dozens of calculations simultaneously. To help move data to and from the GPU as quickly as possible, the card features 1GB of GDDR5 RAM with an effective (QDR) clock speed of 5010 MHz and a 64-bit memory interface.
The GT 640 can be connected to a variety of display types, including computer monitors, HDTVs, and projectors. It features an HDMI port that supports HDCP encryption for viewing Blu-ray DVDs and other copy-protected media, a DVD-D (digital only) port, and a VGA port for analog devices.
Popular API Support
Supports DirectX 11.2 and other APIs to allow GPU-aware applications to benefit from the acceleration provided by a dedicated graphics card, taking much of the workload off your computer's CPU
Nvidia PhysX Ready
Provides faster switching between graphics rendering and physics processing when playing compatible video games
Dynamically adjusts vertical sync during game play, designed to render smoother-looking graphics
ASUS GPU Tweak
Utility software that provides real-time monitoring of GPU performance and can be used to download and install driver and firmware updates
Super Alloy Power
Alloy components and flattened copper heatpipes help to reduce power loss, enhance durability, and achieve cooler operating temperatures to help minimize fan noise and extend the lifespan of the card
Quad Data Rate (QDR) GDDR5 RAM
Because GDDR5 RAM can transfer up to four words per cycle, as opposed to one word per cycle with traditional RAM, the effective data rate is quadrupled, allowing this card to process data transactions as quickly as if it had a 5010 MHz memory clock speed
