New GPUs apparently promise fast frame rates at high resolutions, while still boasting power to spare for physics and even ray tracing
While there are plenty of dodgy-looking tables of specs wishlists for new GPUs on the Web, it’s not often you get a good rumour that looks like the real deal. However, Tom’s Hardware in Taiwan has just leaked a whole load of photos of ATI’s forthcoming Radeon HD 4850 and 4870 cards, all of which look pretty legitimate, as well as a few presentation slides concerning the details.
Unfortunately, there’s nothing about the number of stream processors, although previous rumours point towards the cards having 480 stream processors. However, the slides say that the cards will support both GDDR3 and GDDR5 memory, will have a 256-bit memory interface and will also support 24x CFAA (custom filter anti-aliasing), which the slides say will allow you to smooth out the edges of ‘everything from grass to facial features.’
As well as this, the slides also say that the cards will support HDMI and will be capable of 7.1 surround sound for copy-protected movie discs too. Although there’s no mention of clock speeds or the aforementioned stream processors, if the slides are to be believed, then AMD / ATI is extremely confident in the power of these new beasties. As well as promising a new ‘TeraScale’ graphics engine that will ‘deliver high resolutions and frame rates,’ the slides also say that the GPUs will have power to spare. This, according to the slides, will allow the GPU to process physics and AI, and even ray tracing calculations.
The power requirements are also listed, with a 450W PSU with one six-pin PCI-E connector listed for the single-slot Radeon HD 4850, and a 500W PSU with two six-pin PCI-E connectors for the dual-slot 4870. As expected, both GPUs are listed as supporting DirectX 10.1 and PCI-E 2.0, as well as Quad CrossFire. Of course, this is still all in the rumour mill at the moment, but it looks as though ATI has a lot of confidence in its next GPU architecture if this rumour is to be believed.
