With the introduction of the GF100 core (Fermi) we've been seeing cut down variants appearing slowly. First we saw the mighty GTX-480 and were a little set back when instead of 512 Shaders (Cuda Cores) we were told it had 512 Shaders but only 480 were exposed. Then we saw the GTX-470 Variant and it has 448 Shaders. The drop from 480 Shaders to 448 Shaders made it an attractive, more moderately priced variant that offers most of the power of the GTX-480 at a substantially reduced price. Figure GTX-480 runs right at $500 and GTX-470 runs $350 you lose 32 Shader unit's but save $150 at little cost to performance.Now GTX-465 makes an appearance and it's priced at $280 and has 352 Shaders. So GTX-480 to GTX-470 we lose 32 Shaders and save $150, but GTX-470 to GTX-465 we lose 96 Shaders and save $70. Something is wrong with that price point picture.Going from GTX-480 to GTX-470 we lost 32 Shaders and that's a minor performance drop for the $150 dollar savings, then we lose three times the Shaders from GTX-470 to GTX-465 (32 to GTX-470, 96 to GTX-465) yet the price dropped only $75. So either GTX-465 is a little overpriced for the power it offers, or GTX-470 is under priced for the power.Extending that to the price point GTX-480 would be 100%, GTX-470 would be 70% and GTX-465 would be 56%. Now in our simple minds GTX-470 for $350 at 70% the cost of GTX-480 and having 93.33% of the Shaders of GTX-480 makes more sense than GTX-465 at 56% of the price of GTX-480 with 73% of the Shaders.Let's Take a look at the Asus GTX-465 Voltage Tweak then get into a more in depth look at it's design.
