Power Consumption (Idle and Gaming)
In order to get an idea of a GPU's real world power draw, we run our Crysis 3 2,560 x 1,600 benchmark, which is currently our toughest single screen GPU test. We use a watt meter to measure the maximum total system power draw during the test, and also take an idle reading at the Windows desktop (2,560 x 1,600).

System Power Consumption in Watts
Thermal Performance (Idle and Gaming)
Thermal output is measured using Unigine's free Heaven 3.0 benchmark, as its DirectX 11 features will stress all parts of a modern GPU. We leave all GPU fan profiles and settings as they come. We use the default Unigine settings with a resolution of 2,560 x 1,600 and leave the benchmark running for ten minutes so that temperatures plateau. We record the peak GPU temperature using GPU-Z, and present the data as the delta T (the difference between the GPU temperature and the ambient temperature in our labs). We also take an idle reading at the Windows desktop (2,560 x 1,600).

*As there is no stock model of the AMD Radeon HD 7850 2GB, and we do not have stock samples of the AMD Radeon HD 7790 1GB, AMD Radeon R9 280X or AMD Radeon R9 270 they cannot be included in the thermal performance graphs

Tell me something though, at 1080 res are we starting to see 2GB of memory being maxed out by newer games? Should gamers be looking for 3GB (am I right in thinking you need a memory bandwidth of 384 to use 3GB?) and 4GB cards instead if we want our cards to live longer than the next 12 months? Also, can someone just briefly explain again about the limits factored in by the memory bandwidth as I seem to remember previous comments about a memory bandwidth of 256 not being able to use all of 4GB of memory.
Sorry if the questions are a little convoluted and interlinking.

Its crysis 3 results are pretty poor really 32fps is below what id accept. 36fps in bf4 is basically sub 30fps in 64 player multi for the record so your already not really getting playable fps. Bit has always said 30fps is enough I dont personally agree with that niether does a few others but thats how they review there cards.
Having an extra 1gb of vram or 2gb even would do little for this card.

To access all 3GB in one cycle you would need 384bit bus, as each RAM module uses a 32bit bus AFAIK. You can get cards with more ram like you say with a 256bit bus and 4GB ram, but the ram modules will split the bus between them.

Is this a massive hindrance to GPU performance or something that is virtually insignificant?
I've never really paid much attention to the inner workings of GPU RAM and it's performance attributes.
