Overview
GeForce GTX 285 is a High-End Graphics Card based on the Second Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G200-350-B3 which has 10 Stream Multiprocessors activated and thus offers 240 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 648MHz.

Memory
The GPU accesses a 1GB frame buffer of GDDR3, through a 512-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1242MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 204W, it requires at least a 550W PSU and it requires at least two 6-pin available connectors.

Performance
Gaming benchmarks put its performance considerably above the lower positioned GeForce GTX 280.
It is therefore even faster than the Fermi based GeForce GTX 460 1GB.
