AMD Radeon HD 4770 512MB Review - World's First 40nm GPU
AMD RV740 is all its cracked up to be
The Budget Market Keeps Moving
2008 and 2009 have been very interesting in the world of the GPU - not because we have seen huge increases in available performance (though the GeForce GTX 295 and Radeon HD 4890 are good cards) but because of the dramatic shift to incredibly low priced parts. It wasn't long ago that top-end GPUs were going to run you $599 or more; now you can find AMD's best single-GPU configuration for $230 or so and the computing power encompassed in it is impressive.
Of course as the various new GPU releases came out at lower and lower prices, the remainder of the market has been compressing down into even lower prices and smaller margins. We have seen the HD 4870 and HD 4850 drop to $150 or less and now with today's release, there is a new contender in the sub-$100 market.
AMD Introduces the Radeon HD 4770 GPU
The new AMD Radeon HD 4770 GPU, previously known as the RV740 product, is AMD's updated offering for the $99-109 product segment. This GPU is significant not only because of its pricing and position, but because it is the first GPU to be manufactured on the 40nm process from either GPU vendor. That allows AMD to make the part cheap and power efficient.
Obviously AMD is hoping the new Radeon HD 4770 will take over as the dominant product in the $99 segment.
AMD including GDDR5 memory on such a low cost product is also an interesting move - obviously GDDR3 would save them even more money but they feel that the extra memory bandwidth is required to keep the 640 shader cores fed efficiently.
