EVGA GeForce 7900GTX 512MB graphics card

This EVGA graphics card uses the NVIDIA GeForce 7900GTX GPU with 512MB of GDDR3 memory on a 256-bit interface. It connects through a PCI Express x16 slot and is built for systems that need a DirectX 9 and OpenGL 2.0 compatible video adapter. The core runs at 650 MHz with 24 pixel pipelines.

Dual DVI outputs and SLI support

Two DVI ports allow direct connection to digital displays up to 2048 x 1536 at 85Hz. An HDTV and S-Video output is also provided for analogue screens. The board is SLI ready so a second identical card can be added for multi-GPU rendering in supported applications.

650 MHz core clock with 24 pixel pipelines

The GPU operates at 650 MHz and provides 24 pixel pipelines for fragment processing. Memory runs at an effective 1600 MHz across the 256-bit bus. This clock speed and pipeline count define the card's vertex and pixel throughput for period-correct 3D workloads.

Questions about this item

Will the 512MB GDDR3 memory on the 256-bit interface need replacement as games demand more VRAM?

The 512MB GDDR3 frame buffer is soldered to the board and cannot be upgraded; later titles that exceed this capacity will force lower texture settings or prevent launch.

Which limit appears first when the 650 MHz core and 1600 MHz effective memory clocks run continuously?

Thermal throttling from the GPU die typically arrives before the 400 MHz RAMDAC or 24 pixel pipelines saturate, causing core clocks to drop until temperatures stabilise.

How loud and hot does the dual-DVI GeForce 7900 become under all-day load?

The reference single-slot cooler exhausts heat through the rear bracket; expect noticeable fan whine and case temperatures rising as the 650 MHz GPU sustains full load.
