AMD’s GTX 560 Ti Counter-Offensive: Radeon HD 6950 1GB & XFX’s Radeon HD 6870 Black Edition
Today was originally supposed to be about the newly released GeForce GTX 560 Ti – NVIDIA’s new GF114-based $250 video card. Much as was the case with the launch of AMD’s Radeon HD 6800 series however, AMD is itching to spoil NVIDIA’s launch with their own push. Furthermore they intend to do so on two fronts: directly above the GTX 560 Ti at $259 is the Radeon HD 6950 1GB, and somewhere below it one of many factory overclocked Radeon HD 6870 cards, in our case an XFX Radeon HD 6870 Black Edition. The Radeon HD 6950 1GB is effectively the GTX 560 Ti’s direct competition, while the overclocked 6870 serves to be the price spoiler.
The day has finally come for the Radeon HD 6950 1GB, and today is that day. Truth be told it’s actually a bit anticlimactic – the reference 6950 1GB is virtually identical to the reference 6950 2GB. It’s the same PCB attached to the same vapor chamber cooler with the same power and heat characteristics. There is one and only one difference: the 1GB card uses 8 1Gb GDDR5 chips, and the 2GB card uses 8 2Gb GDDR5 chips. Everything else is equal, and indeed when the 6950 is not RAM limited even the performance is equal.
The second card we’re taking a quick look at is the XFX Radeon HD 6870 Black Edition, the obligatory factory overclocked Radeon HD 6870. Utilizing XFX’s open-air custom HSF, it’s clocked at 940MHz core and 1150MHz (4.6Gbps data rate) memory, representing a 40Mhz (4%) core overclock and a 100MHz (9%) memory overclock. Truth be told it’s not much of an overclock, and if it wasn’t for the cooler it wouldn’t be a very remarkable card as far as factory overclocking goes, and for that reason it’s almost a footnote today. But it wasn’t meant to be, and that’s where our story begins.
