We were not given the idle power consumption however weвЂ™ll see quickly that it hasnвЂ™t improved when looking at our own power consumption numbers.ДЄs we stated earlier, this is NVIDIAвЂ™s shot at the sub-$300 market, which is currently dominated by the Radeon HD 5850 at $289 and up, and the Radeon HD 5830 at $225 and up. NVIDIA pegs the GTX 465 at 200W TDP, 15W below the GTX 470вЂ™s official TDP. With the disabling of additional functional units, the TDP has come down compared to the GTX 470. ItвЂ™s the same PCB and cooler вЂ“ only the GPU has changed, with NVIDIAвЂ™s partners laying down one of NVIDIAвЂ™s GTX 465-binned GF100 GPUs. As a result the GTX 465 takes a straight 25% hit in rasterization abilities compared to GTX 470, slightly greater than the loss for any other part of the GTX 465.ДЄlong with similar clockspeeds as the GTX 470, the GTX 465 also shares the GTX 470вЂ™s design.

By disabling a GPC, not only does NVIDIA surrender CUDA cores, texture units, and polymorph engines, but they also surrender one of the 4 raster engines. This is the first time weвЂ™ve seen them disable a GPC on a GF100 card, making it an interesting first for Fermi. Rather than disabling additional units from each of the GF100 GPUвЂ™s 4 Graphics Processing Clusters (GPCs), NVIDIA outright disabled one of the GPCs. While NVIDIA simply disabled some additional functional units compared to the GTX 480 to get the GTX 470, disabling even more functional units required a different strategy. With all of that in mind, compared to the GTX 470 the GTX 465 may be the more interesting card. The loss of 256MB of RAM will be particularly interesting, as it means NVIDIA has surrendered its memory capacity advantage over AMDвЂ™s reference cards вЂ“ both are even at 1GB.

All told the GTX 465 has around 78% of the texture/shader power of the GTX 470, 80% the ROP power, 76% of the memory bandwidth of the GTX 470, and 80% of the memory capacity. Meanwhile the ROPs have been cut down to 32 ROPs, and another memory controller disabled, making for a 256-bit memory bus attached to 1GB of 802MHz (3208MHz effective) GDDR5. NVIDIA has shut off another 3 Streaming Multiprocessors (SMs) from GF100, leaving the GTX 465 with 11 of them, giving it a total of 352 CUDA Cores/SPs, and 44 texture units. In a nutshell, if you take a GTX 470 and disable some additional functional units, additional memory controllers, and additional ROPs, while turning down the memory speed any further, you get the GTX 465. This brings us to today, and the launch of the GeForce GTX 465. NVIDIA is to the point in the Fermi rollout where they want a piece of that market, and they have a stash of further-binned so-so GF100 chips they want to fill it with. However thereвЂ™s also room for a card below the $350 GTX 470, particularly with AMD being the sole inhabitant of the вЂњbargainвЂќ high-end $300 point.

With the launch of NVIDIAвЂ™s GTX 400 series last month NVIDIA filled in the first 2 spots in their lineup with the GTX 480 and GTX 470, with obvious room to grow out the family in the future.ДЄbove the GTX 480 is of course the вЂњfullвЂќ GF100 with all of its functional units enabled, and which is still missing in action on both the consumer and HPC markets. For the GTX 200 series we had the GTX 260, GTX 275, and GTX 285, while for the Radeon HD 5000 series we have the 5830, 5850, and 5870. In recent years itвЂ™s become customary to have 3-4 high-end cards on the market at the same time using the same GPU.
