Submission + - AMD Radeon HD 7870 and 7850 Pitcairn GPUs Tested

Vigile writes: AMD continues to push forward with the new 28nm process GPUs and completes the 7000-series family with the Pitcairn-based Radeon HD 7870 GHz Edition and HD 7850 cards. The HD 7870 has 1280 stream processors while the HD 7850 has 1024 SPs, both cards have 256-bit memory buses that run at 1200 MHz. As the name implies, the HD 7870 runs at 1000 MHz and is priced at $350 squaring up perfectly with the GTX 570 from NVIDIA and is able to outperform it while using 80 fewer watts of power. The HD 7850 will sell for $250 and simply blows past the GTX 560 Ti again using 50 fewer watts in the process. There are full reviews available at PC Perspective, Tech Report, HardOCP and HotHardware, but it looks like AMD might have a graphics card worth upgrading to.

Submission + - AMD Radeon HD 7950 Bests NVIDIA GTX 580 (

Vigile writes: "Last month AMD released the world's fastest single GPU in the form of the Radeon HD 7970 and now they have another product based on the same GPU technology. The new HD 7950 is based on the Tahiti GPU but has 1,792 stream processors rather than the 2,048 of its larger brother but still maintains the absolutely massive 3GB frame buffer. Performance testing done over at PC Perspective shows that the deltas between the two cards range from 15-20% depending on the game though more importantly the new HD 7950 stays ahead of NVIDIA's GeForce GTX 580 while having a $50 lower MSRP. With features like triple display outputs, lower power consumption than the competition thanks to the new 28nm process and a lot of overclocking headroom, the $449 Radeon HD 7950 could be a great option for high-end gamers if they stay in stock."

Submission + - ASUS MARS II is New Fastest Graphics Card (

Vigile writes: "It seems that every year some graphics card vendor steps up its game and produces a card that puts the others to shame. While AMD and NVIDIA pushed out the HD 6990 and GTX 590 earlier in the year, ASUS has designed another dual-GPU offering dubbed the "MARS II" that combines two true GTX 580 cores for a 25% boost in gaming performance over either previous bests. As you might expect in PC Perspective's testing of the new card the power draw is incredibly high but the temperature and noise is kept minimal thanks to a custom cooler built for the task. Oh and that price — how does $1300 sound?"
