1.4 billion transistors and 240 cores
We managed to get the final Geforce GTX 280 details, and most of the stuff that we've reported over the last few months turned to be true.
Codenamed GT200, the GTX 280 GPU developed in 65nm process and has 1.4 billion transistors clocked at 602MHz. The processor clock, something that we use to call Shaders, works at 1296MHz and Nvidia's new chip has impressive 240 cores.
The GTX 280 card uses GDDR3 memory with 512-bit memory interface clocked to 1107MHz (2214MHz). The card has 141.7GB/s bandwidth and it comes with a total of 1GB memory.
The GT200 chip has 32 ROPs, 80 texture filtering units, 48.2 Gigatexels/sec texture filtering rate. The card supports HDCP, and HDVI via DVI to HDMI adapter and comes with two dual link DVI-I and a single HDTV out.
Ramdac is set to 400MHz, and the card itself is dual-slot with PCIe 2.0 interface and has one 8-pin and one 6-pin power connector. So, now you know.
Nvidia’s second GT200-based card will also be available for sale in about six days and here are the final details and clocks. Geforce GTX 260 is, as well, based on 65nm GT200 core that has 1.4 billion transistors, but this time clocked to 576MHz. Some of these transistors will sit disabled, as GTX 260 has two of ten clusters disabled.
The Shaders are clocked to 1242MHz and the card has a total of 192 Shaders (what used to be called Shader units are now called processor cores).
The card has an odd number of 896MB GDDR3 memory clocked at 999MHz (1998MHz effectively) and this is enough for 111.9GB/s bandwidth. The slower of the chips has 28 ROPs, 64 Texture filtering units and 36.9GigaTexels/second of texture filtering rate.
If you look at these specs closely, you will see that GTX 260 is the same as GTX 280, but with two clusters disabled. If GTX 280 has ten clusters, GTX 260 ends up at eight.
The card has HDCP, HDMI via DVI, but this time two 6-pin power connectors; and launches next Tuesday.
