Before we take a look at the card, we will compare the differences between the 6600GT, Reference 7600GT and eVGA's 7600GT CO.

We see that eVGA has clocked up this "CO" version 20MHz on the core and 100MHz on the memory.  This gives us a few more MTexels and GB per second bandwidth across the card, but not much.  We'll have to see how it adds up when it comes to the benchmarks.  Keep in mind that the 7600GT uses 256MB of memory while the 6600GT only uses 128MB.  That being said, there is a 256MB version of 6600GT as well, however our comparison card only has 128MB.

First Look:

eVGA graphics cards are typically clocked higher and are priced lower than the competition.  What makes them more affordable?  The fact that they don't included anything but the bare essentials with their graphics cards.  The eVGA 7600GT CO ships with a couple of DVI-D to D-Sub adapters, a component video out dongle, S-Video cable, a driver CD, and a small manual.  There are no games or extra software.  Honestly, I find this a little disappointing but I likely would already have the game they'd throw in anyway.

As you can see above, the 7600GT is a relatively short card that won't hog too much room in your case.  Because of its lower power requirements it doesn't require an extra power through a PCIe power connector.  The 90nm process also produces less heat and therefore a small single-slot heatsink is sufficient to keep this card cool.

When you first look at this card, you notice that the fan is a "Blower" type fan.  This fan runs fairly quiet at when running 2D applications, but when running 3D games, it speeds up and makes a fair bit of noise.  When the side of your case is closed, it will help deaden the noise, but it is the loudest component in our test system by far.

eVGA has labeled this card as being Windows Vista Ready, but I don't see any evidence of an HDCP chip on this card.  I hope I'm wrong and if you have information regarding this card's HDCP abilities, I'd love to know.

As is the trend with most GeForce 7x00 series hardware, Dual DVI-D ports come standard.  eVGA has included a pair of DVI-D to D-Sub adapters if you don't have any DVI equipment available.  This way you can still take advantage of dual displays even if you run a couple of CRT's.

eVGA has followed the nVidia reference design to the letter.  The PCB, heatisnk and card features are exactly what nVidia has lain out.  This is not a bad thing though and ensures that the design works.

Closer Look:

To see exactly what makes this card tick, we took a closer look.  We started by pulling off the heatsink to see what kind of finish and thermal compound was used.  The Heatsink appeared to have good contact with the GPU core, and thankfully the TIM could be easily removed and then Arctic Silver Ceramique has applied prior to reinstalling the HSF.

The GPU core is labeled as a GT73 core and is an A2 revision.  This is the second generation of G73 core and may offer some major overclockability.  We'll see if a few minutes.  Notice all the mounting holes around the GPU core on this card.  There should be a whole patter that will fit almost any after-market cooling solution on the market.  The memory eVGA uses on this 7600GT CO is made by Infineon and is their HYB18H512321AF-14 and is rated at 1.4ns or 700MHz (1400MHz DDR).  eVGA has already clocked this memory up to 1500MHz, so I really don't expect much out of it in the way of overclocking.

On the next page we'll take a look at our test system, some testing info then jump right in to the benchmarks.
