Refreshing the GTX 480
Refreshing the GTX 480
Lately, NVIDIA’s fortunes have taken a turn for the better. Although AMD’s latest Northern Islands card - Radeon HD 6870 and HD 6850 - have received largely positive reviews, yield issues mean that there’s not enough cards to go around. Moreover, this has also caused AMD to delay the release of their eagerly anticipated high-end Cayman parts (Radeon HD 6900 series).
In the meantime, NVIDIA capitalized on AMD’s misfortune by releasing their uber-quick 512-core GeForce GTX 580, thereby cementing their grip on the title of world’s fastest GPU. To build on its momentum and to take full advantage of the holiday spending spree, NVIDIA has hastily followed up with the GeForce GTX 570, a card which they say was built with GTX 580 DNA.
But first things first, despite the name, the GeForce GTX 570 is actually more similar to the older GTX 480 than the GTX 470. Based on the GF110 chip that powers the GeForce GTX 580, the GeForce GTX 570 possesses less cores, 480 to be exact, which is exactly the same as the old GeForce GTX 480. Apart from that, the GeForce GTX 570 also has the same number of texture mapping units as the GTX 480, which totals 60.
Where the GeForce GTX 570 is different, however, is that since it is based on the GF110 chip, it has been reworked slightly at the transistor level to make it more efficient. It also boasts the same performance enhancements such as full-speed FP16 texture filtering and support for new tile formats to improve Z-cull efficiency like the GeForce GTX 580. However, the GeForce GTX 570 has eight less raster operating units compared to the GTX 480 and also a narrower 320-bit memory bus width and smaller 1280MB GDDR5 framebuffer.
So to compensate, the GeForce GTX 570 gets higher clock speeds. Compared to the GeForce GTX 480’s 701MHz at the core, 1401MHz at the shaders and 3696MHz DDR at the memory; the new GeForce GTX 570 is running at 732MHz at the core, 1464MHz at the shaders and 3800MHz DDR at the memory.
And although the GeForce GTX 570 was just launched, Palit already have their own customized design for sale and we've got one for evaluation. Factory overclocked and boasting a dual-fan custom cooler, it will be interesting to see how their version improves on NVIDIA’s reference one.
Read on to find out how the two cards will perform, but first, a quick look at how the reference GeForce GTX 570 stacks up against competitive SKUs.
