The Radeon HD 5850 was a performance graphics card by ATI, launched in September 2009. Built on the 40 nm process, and based on the Cypress graphics processor, in its Cypress PRO variant, the card supports DirectX 11.2. The Cypress graphics processor is a large chip with a die area of 334 mm² and 2,154 million transistors. Unlike the fully unlocked Radeon HD 5870 Mac Edition, which uses the same GPU but has all 1600 shaders enabled, ATI has disabled some shading units on the Radeon HD 5850 to reach the product's target shader count.

It features 1440 shading units, 72 texture mapping units and 32 ROPs. ATI has placed 1,024 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 725 MHz, memory is running at 1000 MHz. Being a dual-slot card, the ATI Radeon HD 5850 draws power from 2x 6-pin power connectors, with power draw rated at 151 W maximum. Display outputs include: 2x DVI, 1x HDMI, 1x DisplayPort. Radeon HD 5850 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution.
Its price at launch was 299 US Dollars.
Quote: HIS Radeon HD 5850 1 GB Last week AMD released their new HD 5800 Series. While the HD 5870 was a great hit, the HD 5850 was nowhere to be seen, except in our HD 5870 review where we simulated its performance. Today we present you our review of the HIS 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. The only spec differences are a reduced shader count of 1440 (minus 10%), reduced clocks of 725 MHz core (-15%) and 1000 MHz memory (-17%). As a result the card is roughly 15% slower than the HD 5870, but costs over 40% less, making it an ideal candidate for the price/performance aware user.
'The GDDR5 memory chips are made by Samsung and carry the model number K4G10325FE-HC04. They are specified to run at 1250 MHz (5000 MHz GDDR5 effective).
Those are the same chips like on the big brother HD 5870 - get ready for some serious overclocking.' That last statement doesn't make any sense. Sure the upper limits of the 'overdrive' clocks are low, but everyone is use to this from our experience with the 4000 series. Besides, we all know ways to get around this and up the clocks further than what ATi sets in their bios. I'm saying that by the looks of things, the 5850 is going to OC to the same levels of the 5870. I.e it will be a 1440 sp 5870. If the 5870 can do 1300 on the memory so can the 5850 (seeing as it's using the same stuff).
