BFG GeForce 7800 GS OC AGP Review

Much like its successor, G71, G70 in its full form is made up of 24 pixel pipelines (or six pixel quads), matched up with sixteen ROPs, eight vertex shaders and utilises a 256-bit memory bus. Unlike G71, which was shrunk to the 90 nanometre process, G70 is manufactured using 110 nanometre. The only SKU which uses this full configuration of the core is the GeForce 7800 GTX, together with reference core and memory clocks of 550 and 850MHz respectively for the little-seen 512MB part, and 430 and 600MHz respectively for the 256MB variant. Below this SKU comes the GeForce 7800 GT, which loses a single quad of fragment pipelines (giving it 20 in total) and one vertex shader alongside a core clock of 400MHz and memory clocked to 500MHz on the reference part.

The part we are looking at today, the GeForce 7800 GS, is further reduced in comparison to the GeForce 7800 GT, losing a further quad of pipelines and another vertex shader. This leaves it with a grand total of sixteen fragment pipelines (or four fragment quads) and six vertex shaders. Reference clocks for this SKU weigh in at 375MHz on the core and 600MHz for memory - Of course, BFG's offering in a factory overclocked one, so let's now move on to look at what it has to offer.
