GTX 280 & GTX 260 Final Specs & Performance Page: 1
Release spec for the GTX 280 & GTX 260
The guys over at Fudzilla have reported the final specs for the Geforce GTX 280 & GTX 260, and as it turns out quite a lot of the recent rumours have been proved true.
The GTX 280 which has been developed on a 65nm process, has 1.4 billion transistors and is clocked at 602MHz on the core with the shaders (240 of them) weighing in at 1296MHz. It will use 1GB of GDDR3 memory with 512-bit memory interface clocked to 1107MHz (2214MHz). The card has 141.7GB/s bandwidth.
The GT200 chip has 32 ROPs, 80 texture filtering units and a 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 and should be available to buy within a week.
As for the GTX 260, Nvidia’s second GT200-based card, here are the final details and clocks. Geforce GTX 260 is also based on a 65nm process GT200 core that has 1.4 billion transistors, but this time the core is clocked slightly lower at 576MHz. Some of these transistors will sit disabled, as GTX 260 has two of ten clusters disabled. The Shaders (only 192 this time) are clocked to 1242MHz. This model has a rather odd number of GDDR3 memory.. 896MB clocked at 999MHz (1998MHz effectively) and this is enough for 111.9GB/s bandwidth. The GTX 260 has 4 less ROPs at 28, 64 Texture filtering units and 36.9GigaTexels/second of texture filtering rate. The card has HDCP, HDMI via DVI, but this time two 6-pin power connectors; and should also hit the shelves within the week..
The power requirements for both cards has also been released.
The G200 GTX 280 will need a lot of power. Its maximum board power is set to 236W, which is roughly what has previously been reported. As above it will require one 8-pin power connector and one 6-pin. One 8-pin connector can provide up to 150W of power while a 6-pin can provide 75W as can the PCIe 2.0 slot. If you use one 8-pin and one 6-pin together with PCIe 2.0 you can end up with up to 300W which should easily cover the power hungry GTX 280.
Meanwhile the GTX 260 requires nearly a quarter less power than its bigger brother, thus the need for only two 6-pin power connectors. That coupled with the PCIe 2.0 slot gives it 225W of power while in reality it will only draw a maximum of 182W.
The GT200 chip has a thermal threshold at 105 degrees Celsius, and once the GPU reaches this temperature the clock speeds will automatically start to decrease.
Performance in Crysis
Over at Fud they also reported that they've had a chance to play with a single GTX 280 to gauge how it performs in Crysis.
While Nvidia have claimed that one GTX 280 will be enough for Crysis at 1920x1200, it seems that a single GTX 280 powering a 24" monitor (1920x1200) with FSAA 4X with the beta drivers left the card gasping. Perhaps without the AA filter, 1920x1200 with very high detail might produce decent FPS but we'll have to wait and see.
If you happen to play at a monster resolution of something like 2560x1600, then you will need to SLI-up and get two of these babies. Even then it looks highly unlikely that you will be able to run the game with all the goodies (FSAA) turned up.
With less than a week to go, what do you think? Planning on treating yourself straight away or were you hoping for a little more?
