Thread: Ati radeon hd 5750 and hd5770

Looks like AMD has been hitting all the right notes of late. First it was with the 5800's and now with two simultaneous launches of the 5700's. They couldn't have hit the sweet spot anytime sooner with the Radeon HD 5750 and Radeon HD 5770 especially with the recent launch of Windows 7. With support for DirectX 11 and low power consumption these cards are the current kings for mainstream gaming.

Coming back to the cards, both the Radeon HD 5750 and Radeon HD 5770 are built on a 40 nm manufacturing process and hold the same number of transistor counts which add up to 1.2 billion each. That said, they even have the same memory bandwidth of 128-bit. Almost similar to what the two 5800's shared. The HD 5770 is a tad smaller than the HD 5870 but share the same cooler. In fact both the Radeon's HD 5770 and the HD 5870 are so similar that they share the same 850 MHz for clock speed and 1.2 GHz for memory speed. What sets them apart are the number of stream processing units which boils down to a total of 800 for the HD 5770.

Alternatively the Radeon HD 5750 is fit with an open air cooler that resembles the shape of an egg. The core and memory are clocked at 700 MHz and 1.15 GHz respectively with a total of 720 stream processing units under its hood. Both these cards include a Dual DVI port, an HDMI port and display port thereby allowing you to connect a total of three display devices.

Both cards handled games rather well with Crysis (1680 x 1050, 2xAA) and Left 4 Dead (1680 x 1050, 8xAA) returning a score of 26 fps / 51 fps for the HD 5750 and 31 fps / 55 fps for the HD 5770 respectively. Even with so much power under its hood the HD 5770 topped out at just 170 W when on load. That's 45 W lower than the previous HD 4770.
