XFX HD 5850
The HD 5850 is based on the same Cypress GPU like the HD 5870, it has the same GDDR5 memory and supports all the features its bigger brother has. XFX's card uses reference desing, and the card comes with a coupon for the game Dirt 2.
The GPU runs at 725MHz and the 1024MB of GDDR5 runs at 1000MHz. All the memory is located on the GPU side of the PCB, and unlike the pricier HD 5870, there's no backplate. The cooling is dual-slot and does a great job without making too much noise, as temperatures rarely exceed 80 degrees Clesius. The highest temperature we measured on the HD 5850 was 85 degrees Celsius, but those were measured in the most intensive tests.
The card uses GDDR5 memory of higher quality than on the HD 5700 series, and we're talking about Samsung's K4G10325FE-HC04 memory rated at 1250MHz (5000MHz GDDR5 effectively).
The box puts an emphasis on the ATI Eyefinity technology. Appart from the option to chain up to three monitors on one card, the HD 5850 allows for using them as one monitor with a higher resolution spread across three monitors. The card comes with two dual-link DVI outs, one HDMI and one DisplayPort video out.
The card requires two 6-pin power connectors.
All our today's XFX cards came in identical packaging, but with different emphasis points of course. All the cards have XFX 5-star support and the HD 5850 puts an emphasis on the Dirt 2 gift-game.
