Specs of GT218 Graphics Card Surfaced

According to the GT218 card drawing leaked by VR-zone and other information around, we start to have an idea of how this card would look like. GT218 shares the same core structure with G9x, instead of using the second-generation rendering structure just like GT200. But its manufactured based on 40nm processing technology, so GT218 is essentially a G96 in 40nm version.

GT218 is equipped with 32 stream processors, which is similar to 9500GT, and doubled from 9400GT. Rumor has it that GT218 has 8 texture mapping units (TMU), but it seems doubtful considering the features of G9xs structure. Actually it should be featuring 16 TMUs. The core/memory clock of GT218 (550/800MHz) is the same as 9500GT GDDR3 Edition. The shader clock is 1375MHz, a little bit lower than 9500GT&9400GT. Considering the engineering sample of 9500GT&9400GT also featured 1375MHz shader clock, so it wont be surprising if NVIDIA updates it to 1400MHz when bringing out GT218 officially.

The memory interface of GT218 is only 64bit, compared to 128bit of 95000GT/9400GT. Thanks to GDDR3, its memory bandwidth is on a par with 9400GT.

40nm processing means reduction in power consumption. Its said that the TDP of GT218 is 22W, but this should refer to power consumption of the GPU only. The maximum power consumption of the whole card is expected to be around 40W.Judging from the specification, the performance of GT218 might be between 9400GT and 9500GT. As an entry-level graphics card, users might be more focused on its low power consumption than how well it performs.
