Our testing procedure entails a 30 minute period of idle testing from cold, followed by a 30 minute period of Furmark's Stability Test. Temperatures are noted with the fan set to Automatic and at a fixed speed of 50% for the sake of a fair test.

Our first observation was that the 1GB version of the card runs slightly warmer with all of its ROPs and Memory Interface enabled. Another reason for the higher temperatures is the graphics card's higher core frequencies but more importantly, its higher default voltage of 1.01V vs the 0.97V recorded on our 768MB Reference card.

With the fan set to Auto, we reached a maximum Load temperature of 64*c with a maximum duty speed of 54%. Reducing the fan speed to a fixed 50% lowered the motor noise of the fan quite noticeably, however the load temperature had risen to a more toasty 71*c. These results were a little higher than we expected, however on the basis of the card's higher operating voltage and its fully enabled specification, it is certainly reasonable.

This is where things get a little interesting. Without manipulating Core Voltages, we reached a maximum stable frequency of 852MHz. We weren't entirely happy with this so after a 0.05V voltage increase, we finally found ourselves with a speedy 881MHz Core and a consequent Shader Frequency of 1762MHz. The memory on the Asus DirectCu was also impressive as we obtained a maximum frequency of 4160MHz. Great results all round!

So without further ado, lets whack out the benchmarks!

Still not impressed by the all new GTX 460? Perhaps Asus' rendition might be able to persuade you...

There's no doubting the performance of this card, the extra memory and bandwidth definitely help with increasing minimum frame rate considerably and giving a boost overall. My issue is, why did ASUS change from a clean black and red for ATi and black and green for Nvidia, to the rather curious blue tone? I'm not a massive fan personally, but I know there'll be people who like the new scheme. Still, I doubt it would stop me from buying it if I wanted a well-made 460!Quote

Excellent review specially the part where you compare the cars to the cards only I noticed two things first CRYSIS is not playable at 17 fps minimum I know that (1920X1080 4XAA 8XAF Enthusiast) are a bit extreme but you should have tested on high settings instead of enthusiast with 2XAA, second CCL don’t have this model from ASUS they only have the 768mb model for 188£ so I don’t know where you got the 195£ from on top of the page anyway great stuff Mr Chidrawar and of course tom.Quote
