AMD working on Radeon HD 3830
AMD's Radeon HD 3830 is a spin-off chip based on the RV670 core and will feature a 128-bit memory bus, potentially providing roughly half the memory bandwidth of the HD 3850 and 3870 depending on the type and speed of memory used. All other features of the 55nm RV670 core are still included: DirectX 10.1, PCIe 2.0 and UVD. The GPU still features 320 stream processors like the HD 3850 and HD 3870 revisions.
According to recent reports, the HD 3830 will feature up to 256 MB of memory and come with 320 stream processors as well as 16 texture filtering units and 16 raster operators to match the HD 3850/3870 models. This is compared to the 32 stream processors, 16 texture filtering units and 8 raster operators of the 8600GTS's G84 core.
Pricing of the Radeon HD 3830 scheduled on roadmaps in the $120-130 range, however with Radeon HD 3850 prices quickly approaching that, 3830 street prices could easily hit the $100 price point.
AMD roadmaps peg the launch of Radeon HD 3830 at mid-April, with initial shipments likely not hitting the U.S. until several weeks later.
Looks like a nice enough card, and if it does hyrbrid crossfire with the 780G amd boards, should be real nice combo to own.
