ATI Radeon HD 4830 Mainstream GPU

Since the RV770 GPU's initial arrival, we have seen the technology used in the GPU migrate up and down AMD's product stack. At first, the RV770 powered only the ATI Radeon HD 4850 and 4870, but soon thereafter two RV770's were linked together to form the current flagship Radeon HD 4870 X2. Then the GPU was scaled down to bring out the Radeon HD 4600, 4500, and 4300 series of products. Ultimately, AMD ended up with competitive offerings at virtually every price point, ranging from $39 on up, to over $550 for the flagship product. But there is an approximate $80 price gap between the $160-ish Radeon HD 4850 and the roughly $80 Radeon HD 4670, that AMD plans to fill today with the release of the Radeon HD 4830.

As its name suggests, this latest addition to the Radeon HD 4800 series is similar to the Radeon HD 4850. In fact, the reference designs look almost identical. The 4830 however, has had a couple of SIMD arrays disabled, and hence has fewer active stream processors and TMUs. We'll show you what other differences there are a little later. For now, check out the specs and other related information. We'll get on with the show right afterwards...
