EVGA GeForce GTX 780 Ti SC SuperClocked ACX Review




In this review, we test the EVGA GeForce GTX 780 Ti SC SuperClocked ACX review, armed with that 450W cooler and our FLIR camera we'll see if it really is good cooling. Oh and hey, SC means a factory overclock - this thing is fast! NVIDIA unlocked the GPU completely meaning all 2880 Shader processors are available. That combined with increased core and memory clock frequencies and nice overclock potential will make this the flagship product to purchase for the Christmas holiday season.

Very impressive, but is still over priced.
This should be priced at around $600.
plus only 3GB of VRAM?
I am getting close to the 4GB on my 290s in BF4 @ 1600p with the resolution slider at 160%.
I never understood why you can buy the 760s and 770s with 4 GB but their higher end models only have 3GB VRAM, it doesn't make sense to me. Unless there is a tech limitation or something preventing 4GB on the 780s. There is no limitation in ripping people off. They know that as soon as gamers get a 4k monitor, they will want to get a new gpu.

It is a technical limitation. The memory bus on 760/770 is 256bit and the memory chips have to be divisible by that: 256mb x 8 chips for 2gb (2048mb) or 128mb x 8 for 1gb or 512mb x 8 for 4gb. If asymmetrical, it loses efficiency/performance. The 780/ti/Titan have 384bit busses which in the same way can only be 3/6gb. There are ways around it and exceptions to the rule (ie, 660ti with 192bit bus/2gb), but I dont think Nvidia is keen to do this on their upper end cards.
Same applies to AMDs cards: 290/x = 512bit bus, 4gb. 7950/7970 = 384bit, 3gb cards.

I figured it must be something like that (tech limitation), it would not have made sense otherwise. Thanks for sharing.
