NVIDIA Quadro 5000 is one of the three models of Fermi-based professional graphics cards (see this page for an overview).The Quadro 5000 is based on the same GPU than the GeForce GTX 465: it is based on the GF100 with 352 SP (shader processors). But the Quadro 5000 comes with 2.5GB of graphics memory whereas the GTX 465 exposes only 1GB. And another difference is that Quadro 5000 graphics memory has a 320-bit bus with and supports ECC (error correcting code).
NVIDIA Quadro 5000 main specs:
- GPU: GF100 @ 513MHz
- Memory: 2.5GB GDDR5 @ 750MHz real speed (or 3000MHz QDR speed) with ECC / 320-bit
- TDP: 152W
- Power connectors: 1 x 6-pin
- Price: around US $2250
Power consumption and GPU temperatures
In comparison with the GTX 465, Quadro 5000 shows a reduced power consumption: around 50W in less. According to PC Perspective, One reason is the better quality of the silicon used:
Obviously because the Quadro line is worth so much more to NVIDIA in terms of profit margin, the company has been and will be hoarding the best dies from the wafers for these cards and what we are seeing is a result of hand picking GPUs that run more power efficiently than the others.
X-bit labs gets similar results with FurMark: around 150W.
Another interesting fact:
Gaming load differs greatly from what the graphics card has to face in professional 3D applications. There is no wonder that the GeForce GTX 470 is much faster than the Quadro 5000. The GF100 chip of the gaming card has more unlocked multiprocessors and thus delivers higher performance in games where the speed of shaders is more important than the speed of drawing and texturing of triangles.
