The high 30 days know seen a ton of new technology, from Intel's Lynnfield-based Nucleus i5 and Ngo i7 processors (which we reviewed here, tested in a confine of assorted games with CrossFire and SLI setups here, and sounded the force of united PCI Verbalise 2.0 conservative here) to ATI's Cypress graphics processor (manifest finished the Radeon HD 5870 and Radeon HD 5850). Between those move stories, I've run thousands of measure numbers and inscribed tens of thousands of words. Thus, when I sat felled to create this Radeon HD 5770/5750 brushup (after running other 500+ tests), I had to mix it up a bit and hit a young fun with the intro.


Consider Retributive A Somebody.If the Radeon HD 5870 was defined by roughly twice the technology resources as Radeon HD 4870, then the Radeon HD 5770 represents a halving of Radeon HD 5870. You'd believe that'd succumb something that looks a lot equivalent the Radeon HD 4870 to which you're already accustomed-and you'd be fill to accurate.The Radeon HD 4870 is supported on ATI's 55nm RV770, sportsmanlike 956 million transistors on a 260 paddle millimeter die.

It boasts 800 ALUs (shader processors), 40 texture units, a 256-bit retentiveness interface spiny with GDDR5 retention (cranking out 115.2 GB/s), and a depth/stencil measure of 64 pixels per measure.In contrast, ATI's 40nm Juniper GPU is prefab up of 1.04 1000000000 transistors. It also wields 800 shader processors, 40 texture units, and a depth/stencil grade of 64 pixels per quantify.


But its memory programme, existence a halved variant of Conifer,' is only 128-bits wide. Still, ATI munition it with GDDR5 faculty able to act up to 76.8 GB/s.Suitable off the bat, we knew that this was going to be a really uneatable comparison-not only between ATI and Nvidia, but also between ATI and its own lineup of products. Yes, both of these new game leverage DirectX 11 argue.
