NVIDIA Fermi GeForce GTX 470/480 cards scarce at launch?

NVIDIA Fermi GeForce GTX 470/480 cards scarce at launch?

AMD are hammering away with their DirectX 11 graphics cards - the ATI Radeon HD 5830 made official this morning is a good example - but things may not be quite so ship-shape over at NVIDIA.  According to DigiTimes' sources, despite NVIDIA's intent to announce their Fermi-based GeForce GTX 470/780 GPUs on March 26th, there'll be a limited number of actual shipping cards at the time.  That, they reckon, is down to NVIDIA's reluctance to part with reference board designs.

AMD have announced their latest graphics card, the ATI Radeon HD 5830, just as they were predicted to last week.  The HD 5830 slots into the sub-$250 bracket and supports DirectX 11, ATI's Eyefinity multi-display technology and ATI Stream; however it also confirms yesterday's leaked specifications, which revealed that the card would not be as powerful - in comparison to its HD 5850 sibling - as some users had anticipated.

Specifications for the much-anticipated ATI Radeon HD 5830 have leaked, courtesy of Chinese site IT168.com, and there's a little disappointment in store for anyone expecting a bargain HD5850 alternative.  The slide - which is tipped to have come from an internal presentation deck - confirms the rumored $250 pricing window, but also that the new card is down a significant 320 stream processors, 16 texture units and 16 ROPs on the HD 5850.

ASUS Republic of Gamers overclocked Radeon HD 5870 leaks

ASUS Republic of Gamers overclocked Radeon HD 5870 leaks

Details of an upcoming ASUS Republic of Gamers (ROG) graphics card have emerged, complete with some early photos, and it seems the company have taken an ATI Radeon HD 5870 and overclocked it.  The fettled card cranks the GPU from 850MHz to 900MHz and doubles RAM to 2GB of 4.9Gbps GDDR5 memory.  Meanwhile ASUS are apparently making it straightforward to overclock the ROG card a little more again, with up to 1080MHz possible from the GPU and 5.2Gbps from the memory.

NVIDIA Fermi GF100 detailed: ATI-besting GPU

NVIDIA Fermi GF100 detailed: ATI-besting GPU

NVIDIA have been spilling the beans on the Fermi GF100, the company's 40nm GPU with a full 512 CUDA cores, which they reckon will deliver not only exceptional gaming performance but film-like geometric graphics.  To do so, they've thrown out much of the traditional graphics pipeline structure and introduced far more parallel geometry processing; in fact the GF100's GigaThread engine can flip between contexts - DirectX 11 for rendering, CUDA for selective ray tracing, Direct Compute for post-processing and PhysX for simulations - in around 20 microseconds.
