and well that's all followed by power consumptions, heat levels and performance measurements of course.Īnyway, let's talk about architecture and then focus on the HIS Radeon HD 6990 graphics card. As such the Radeon HD 6990 comes with a flabbergasting 4 GB of graphics memory, that's two GB per GPU.Īll in all, we'll have a lot to talk about today, we'll have a quick chat about verbs like Barts, Cayman and Antilles, then we'll describe the architecture a bit better, we'll have a close look at the products with the help of a photo-gallery. In such setup it's wise to have a little more memory per GPU, especially with stuff like high anti-aliasing levels in mind. Memory wise, AMD decided not to skimp here either, the Radeon HD 6990 is a card that will be perfectly suited for Eyefinity solutions, say 3 to 5 monitors PER Radeon HD 6990. AMD Crossfire setups, including the 7990, were doing little if anything to mete out frames in an even manner, resulting in a range of outcomes from badly paced frames to dropping frames altogether. Now I've stated it, Cayman XT GPUs, that means the full shader processor count inside that GPU is available, that sums up towards 3072 shader processors! AMD stuck two Cayman XT GPUs (R6970) onto the PCB and allows them to be clock at R6970 speeds as well, in fact you'll get options in clock-frequencies and TDP with the help of a small micro-switch seated on the card, which leads to 2 vBIOS, one with more acceptable TDPs and the other enabling a higher clock frequency mode. Nobody really could confirm what GPUs would be used, how much graphics memory it would get and so on. The performance numbers you will see are anything short from astonishing, breathtaking stuff for a wicked product.įor many weeks now the Radeon HD 6990 has been a product of much discussion. And for now it will be the fastest "single" graphics card available on the planet. Radeon HD 6990 ladies and gentlemen is AMD's latest ATI Radeon HD dual-GPU based graphics card. we can also look into CrossfireX performance, that's right. Brand new install of 7990, never previously used this card on any pc. This is the first die shrink since the release of the GTX 680 at which time the manufacturing process shrunk from 40 nm down to 28 nm. It features the new 16 nm (down from 28 nm) Pascal architecture. Windows 10 fully updated DXDIAG reports no problems Radeon software version 19.4.1. The GTX 1080 is Nvidia’s new flagship graphics card. With one distinct difference, since we have two cards. Gigabyte mobo w/ crossfire support one AMD HD 7990 card, monitor plugged in to one of the miniDP ports on it, not the dvi port. The card itself is 100% reference with a HIS sticker on it, as such many segments of this review will be similar to the reference review. In this round we'll be looking at an actual retail sample flown in with the speed of light by HIS technology. It's time for the second review based on that beast of a graphics card called Radeon HD 6990.
