GIGABYTE Rolls Out Radeon HD 7790 with Triangle Cooling

[btarunr]

GIGABYTE rolled out a pair of Radeon HD 7790 graphics cards, the GV-R779-1GI, which sticks to AMD reference clock speeds of 1000 MHz core and 6000 MHz memory, and the factory-overclocked GV-R779OC-1GI, featuring 1075 MHz core, and 6400 MHz memory. The two offer GIGABYTE's UltraDurable VGA PCB, and its Triangle Cool fan-heatsink that pairs a large 100 mm fan to a copper-embedded aluminum heatsink. Based on the 28 nm "Bonaire" silicon, the Radeon HD 7790 packs 896 stream processors, dual tessellation units, 56 TMUs, 16 ROPs, and a 128-bit GDDR5 memory interface holding 1 GB of memory; and a brand new dynamic-clock technology. The base model is priced at US $149.99, and the OC model at $159.99.

Then bucks ain't much but it's always a guessing game if the OC'd unit has the same reserve or is just a ruse and the two units are identical in performance capability...

*Ten, I would think the OC'd version would be tested for stability at higher freq's and so would probably clock even higher with decent cooling.

i dont think this is the case, its just a mild oc that every card can do.

No, the chips has to fall within an acceptable error limits UCL(upper control limit) and LCL(lower control limit) for that batch. No company is dumb enough(except OCZ apparently) to continue with productions if they are not at least 99% confidence. Ever heard of six sigma? operations management use that especially in the electronics industry.
That being said, the higher the OC then the more chips will not fall within the UCL and LCL. You can conclude that the higher the OC then the higher the board quality to maintain the same confidence. Unless the company wants a high rate of returns...

Gigabyte's HD7790 has worse cooler than AMD's reference design
