The GeForce GTX 465 was a performance-segment graphics card by NVIDIA, launched on May 31st, 2010. Built on the 40 nm process, and based on the GF100 graphics processor, in its GF100-030-A3 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GF100 graphics processor is a large chip with a die area of 529 mm² and 3,100 million transistors. Unlike the fully unlocked GeForce GTX 480 Core 512, which uses the same GPU but has all 512 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 465 to reach the product's target shader count. It features 352 shading units, 44 texture mapping units, and 32 ROPs. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GTX 465, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 608 MHz, memory is running at 802 MHz (3.2 Gbps effective). Being a dual-slot card, the NVIDIA GeForce GTX 465 draws power from 2x 6-pin power connectors, with power draw rated at 200 W maximum. Display outputs include: 2x DVI, 1x mini-HDMI 1.3a. GeForce GTX 465 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution. Its price at launch was 279 US Dollars.

GF100 GPU Notes
PureVideo HD: VP4
VDPAU: Feature Set C
GF100 has 4 GPCs each capable of 8 pixels per clock. This limits complete GPU to 32 pixels per clock and because of that it can't feed all 48 ROPs when they all require data at the same time.
Additional ROPs however can be used for MSAA (because it doesn't require additional data from rasterizers, while giving more work to ROPs.)
