<p>Announced and launched on May 31, the GeForce GTX 465 is NVIDIA's third Fermi-based graphics card, after the GeForce GTX 480 and GTX 470. And with a launch price of US$279, the new GeForce GTX 465 was clearly introduced to address the lack of a more affordable Fermi graphics card.</p>
<p>An affordable Fermi solution is critical, because ATI already has the advantage, considering that almost their entire line up of Evergreen cards (save for the Radeon HD 5830) have been available since the start of 2010. And with both the GeForce GTX 480 and GTX 470 costing upwards of US$350, it is clear  that the aforementioned SKUs are geared towards hardcore gamers and that NVIDIA cannot possibly rely on them to gain ground in the DirectX 11 graphics market.</p>
<p class="rtecenter"><img height="266" width="500" src="/files/images/intro_16.jpg" title="NVIDIA's GeForce GTX 465 arrives en mass into our labs. We put it to the test." alt="" /></p>
<p>In terms of specifications, think of the GeForce&nbsp;GTX 465 as a weaker version of the&nbsp;GTX 470. One of the more important things to note is that it gets 96 lesser CUDA cores, bringing its total count to 352 CUDA cores. That also means it has lesser texture mapping and raster operating units - 44 and 32 respectively compared to a GTX 470 card with 56 and 40 units respectively. Memory bus width has also been cut down from 384-bit to a narrower 256-bit. Consequently, framebuffer size has been reduced as well, from 1280MB to a 1GB.</p>
<p>However, the GeForce GTX 465 keeps up by sharing the GTX 470's core and shader clock speeds: 607MHz at the core and 1215MHz at the shaders. Additionally, the GeForce GTX 465 continues to employ GDDR5 memory, but that is running at a slightly slower 3306MHz DDR, as opposed to the GeForce GTX 470's 3348MHz DDR. All in all, the GeForce GTX 465 takes a pretty big hit in terms of paper specifications, so it'll be interesting to see how it'll perform.</p>
