Fermi and Specifications

Though the GTX 580 and GTX 570 share the same GF110 architecture, there are several differences. The 570’s specifications look like a neutered version of the 580. This is achieved in a couple of ways. First, one Polymorph Engine has been disabled, resulting in a reduction of 32 CUDA cores and also 4 Texture Units. Second, a 320-bit memory interface is used here rather than the full 384-bit, and there’s 1.28GB of GDDR5 rather than the 1.536MB of the GTX 580. Lastly, the clock speeds have been slightly lowered from the 580, down to 732MHz core and 950MHz memory.

The diagram below shows the architecture of the GTX 580.

Now compare this to the GTX 570:

Perhaps the best way to further show the difference between the two cards is to lay out the specifications. Below is a chart that shows the specifications in the current GeForce premium GTX lineup as things stand from Nvidia:

As you can see, the GTX 580 is a powerhouse, while the 570 is just a bit lower on the performance ladder. The 560 Ti is even further down, treading more into the performance mainstream market.

Below are GPU-Z screenshots that show the particulars of each card. As you can see, the notable differences are in the memory amount (1.2GB vs 1.53GB), bus (320 bit vs 384 bit), ROPs, and shaders as mentioned. Core and memory clock speeds are also different as well. However, as we’ll soon see, the cards physically look nearly identical.

Here is the ASUS GTX 570 Direct CU II:

Let’s move onto the package and accessories.

    What did you end up pushing the voltage to? 1.1V?

      I believe so. It’s been awhile since we did that testing/review, but typically we push the voltage to the maximum in order to see what’s possible/allowed by the various card manufacturers. Keep in mind though, this will have an effect on higher temperatures and increased fan noise.
