A Closer Look
The GeForce GTX 580 is one of the few graphics cards that uses a vapor-chamber technology heatplate to maximize heat transfer between the GPU and the rest of the heatsink. You can also see above that the heatsink cools secondary components like voltage regulation circuitry and memory chips. Overall this seems to be a very capable thermal solution but that also increases its price.
NVIDIA's 6+8 power input configuration is sufficient for the GTX 580 design and provides up to 300 W.
The GDDR5 memory chips are made by Samsung, and carry the model number K4G10325FE-HC04. They are specified to run at 1250 MHz (5000 MHz GDDR5 effective).
Just like on the GeForce GTX 480, NVIDIA uses a CHiL CHL 8266 voltage regulator on their card. This controller offers extensive monitoring and voltage control options via I2C, so it's a great choice for overclockers.
NVIDIA's GeForce 110 graphics processor is made on a 40 nm process at TSMC Taiwan. It uses approximately 3.0 billion transistors which is 200 million less than the GF100. Please note that the silvery metal surface you see is the heatspreader of the GPU. The actual GPU die is sitting under the heatspreader, its dimensions are not known. According to NVIDIA, the die size of the GF110 graphics processor is 520 mm².
