"The new GeForce GTX 570 delivers the world's fastest DX11 performance in its class, and is up to 128 percent faster in today's newest DX11 tessellated games." ---NVIDIA

may be unpredictable sometimes. Following the release of GF110-based GeForce GTX 580 1.5GB last month, flexes their muscles with the abrupt release of the cheaper follow-up, in the name of GeForce 1.3GB.

What’s new?

At a glance, there’s a very little difference between the GTX 580 1.5GB and the new GTX 570 1.3GB. Bothuses 10.5in-long PCB and glossy plastic shroud. The only obvious difference is the lesser power phase circuitry on the end of the card; more on that latter.

While the GTX 570 1.3GB look very much like a GTX 580 1.5GB on the outside, the inside is where the changes are found. The most notable of which is that the GTX 570 1.3GB uses 480 stream processors. Does it rings a bell? The GTX 480 1.5GB used the same, with the last SM (Streaming Multiprocessor, or block of 32 stream processors) of the GPU’s design disabled.

The newest model also lopped off a memory controller unit reducing the memory interface to 320-bit rather than the 384-bit interface of the GTX 480 1.5GB and the GTX 580 1.5GB. It reduces the GPU’s ROP count to 60 and its Level 2 cache from 768KB to 640KB. With one less memory controller in the GPU, the amount of physical memory drops to 1,280MB.

Here’s the Official Press Release for the GTX 570.
